Field
This invention relates to a mixing vial for storing and mixing first and second components. More specifically, it relates to a mixing vial having a mixing container for holding a first component and a supplemental container for holding the second component in a sealed condition, and manually operable release mechanism for opening the supplemental container to permit mixing of the first and second components in the mixing container.
Background
In the medical field there are many solutions which are administered in liquid form, such as by needles and syringes, jet injectors, aerosol dispensers, or other devices. Many such solutions may need to be packaged and stored with a liquid first component separated from a second component. In the past this often has been done with separate containers which must be accessed individually and the components combined for mixing.
Some past attempts have been made to provide a single container which has multiple compartments therein for holding separated components with a sealing mechanism therebetween. Although such have provided separate container regions for segregated components and means for displacing a seal therebetween to allow mixing of the multiple components, such prior devices have not been as economical and convenient to use as may be desired.
An example of an area in which great need exists for improved storage and mixing of multiple-component mixtures is in the field of vaccination against diseases. For example, programs to vaccinate against measles require the storage of lyophilized virus separate from a sterile diluent until a time when such is needed for vaccination purposes. Near the time the mixture is needed, the two components (lyophilized virus and sterile diluent) in the previously-known systems often required reconstitution of the vaccine by drawing sterile diluent from a sealed vial (via needle and syringe) and injecting it into another sealed vial containing the lyophilized virus. The vial containing the two components (diluent and
lyophilatc) then is shaken to mix the components, or constituents, and achieve rcconstitution of the vaccine. Thus, even if a needle-free administration technique for the vaccine subsequently is used, the rcconstitution process requires the use of needles and syringes producing opportunity for contamination through the re-use of dirty needles, the need to dispose of used needles and syringes, the possibility of use of improper diluents, the possibility of measurement errors in obtaining the proper dilution, and the possibility of needle-stick injuries by workers.
Moreover, as commonly used in the field, the need for separate supply vials for vaccine and diluent requires multiple sterile containers to be ordered, transported, inventoried, coordinated and monitored.
What is needed is an improved mixing vial system for storage, transport and reconstitution of components, such as lyophilized vaccines, or other products.
Summary
The present invention is directed to a mixing vial, or apparatus, for storing and mixing first and second components and includes a mixing container for holding the first component, a supplemental container of liquid impermeable material received within the mixing container for holding the second component separated from the first component, and manually operable release mechanism for opening the supplemental container to permit mixing of the first and second components to form a combined mixture in the mixing container.
In one aspect of the invention, sealing mechanism releasably holds a first end of the supplemental container in sealed relationship adjacent a septum which closes a first end of the mixing container, and release mechanism is manually operable to shift the supplement container from its sealed relationship.
In another aspect, the supplemental container has an open end directed into the mixing container and a closure member releasably connected to and closing such end of the supplemental container, with release mechanism manually operable to force the closure member from its closure position to release component held in the supplemental container into the mixing container.
In another aspect of the invention, a mixing container having a septum closing one end thereof has a supplemental container mounted for shifting therein and biasing mechanism within the container yieldably urges the supplemental container toward the septum, such that the rim of an open mouth of the supplemental container sealingly engages the septum to permit the supplemental container to hold one component material separated
from another component material held in the mixing container and a manually operable release mechanism is capable of shilling the supplemental container against the yieldable biasing force of the biasing mechanism out of its sealed condition permitting mixing of the two components.
In another aspect of the invention, a mixing container is capable of holding a first component and a supplemental container is provided in the mixing container for holding a second component, with the supplemental container having a rupturable portion and release mechanism in the form of manually operable means for breaking the rupturable portion of the supplemental container to permit mixing of the components to provide a combined mixture in the mixing container.
More specific aspects relate to features of the sealing mechanism for sealing an open end of the supplemental container, and manually actuatable operator members to cause the supplemental container to be opened to release component material held therein.

Detailed Description
Referring to the drawings, and first more specifically to Figs. 1 A, 1B, 1C, at 10 is indicated generally a mixing vial, or apparatus, according to an embodiment of the invention. The mixing vial includes a generally conventional, substantially cylindrical mixing container 12 having a neck portion 12a and radially outwardly projecting annular rim, or lip, 12b adjacent its open end 12c. Container 12 also has an annular shoulder 12d adjacent neck 12a. The end of container 12 opposite open end 12c is closed by a bottom wall 12e. Container 12 is capable of holding a component to be mixed within the container such as lyophilate indicated generally at 14.
The open end 12c of container 12 is sealingly closed by a flexible elastomeric septum 18. Septum 18 has an outer rim with an under surface 18a which rests sealingly against the top of lip 12b. A substantially cylindrical sealing ring portion 18b depends from under surface 18a, extends inwardly of the container and has a substantially cylindrical inner surface 18c. The central portion of septum 18 indicated generally at 18d initially is bowed upwardly in the convex curved configuration illustrated in Fig. 1 A. Portion 18d may be pressed downwardly to assume the downwardly curved, or concave, configuration shown in Fig. 1B as will be described in greater detail below.
Sealing septum 18 is secured in place on the open end of container 12 by a holding member 22. The holding member has a substantially planar upper portion 22a with a
circular opening 22b formed therein through which central portion 18d of the septum projects and is accessible. A cylindrical skirt portion 22c of holding member 22 extends downwardly about the outer edges of septum 18 and rim 12b of container 12 and is folded inwardly under rim 12b to fixedly hold septum 18 in tight engagement with rim 12b to sealingly close end 12c of container 12.
A liquid impermeable supplemental container 26 having a generally test tube shape is received in container 12. Supplemental container 26 has substantially cylindrical sidewall 26a with a closed lower end 26b and an open upper end 26c. Open end 26c is surrounded by a neck 26d having a selected configuration, in this situation cylindrical.
The inner surface 18c of sealing ring 18b has a configuration complementary to neck 26d of container 26, such that in the position illustrated in Fig. 1A the open end portion of supplemental container 26 is frictionally gripped and held in sealing relationship in sealing ring 18b. The end rim of supplemental container 26 may be held firmly against the underside of the septum.
Supplemental container 26 is adapted to hold the other component, such as liquid, or diluent, 30 separated from the first-mentioned component 14 held in container 12.
An elongate rigid rod 34 is received in supplemental container 26 and extends from the lower end 26b of container 26 to the underside of portion 18b of septum 18. In a non-operating position illustrated in Fig. 1A, rod 34 merely rests within the confines of the supplemental container and septum such that the supplemental container continues to be held sealingly in sealing ring 18b.
An actuator cap 38 having a substantially planar outer portion, or top, 38a and depending cylindrical skirt 38b is shiftable between a non-operating position as illustrated in Fig. 1A and an operating position as illustrated in Fig. 1B. An actuating protrusion 38c is formed on the underside of top 38a to engage the upwardly bowed central portion 18d of septum 18.
A safety member, or ring, 40 is interposed between the lower end of skirt portion 38b of the actuator cap and a shoulder 12d on container 12. In the safety position for member 40 illustrated in Fig. 1A, cap 38 is prevented from being shifted downwardly from its non-operating position as illustrated in Fig. 1A. However, the safety member 40 may be physically removed (also referred to herein as moved to a release position) when it is desired to mix components in the containers. Upon removal of the safety member actuator 38 may be shifted downwardly to its operating position as illustrated in Fig. 1B.
Thus, following removal of safety member 40, cap 38 may be manually shifted downwardly, with protrusion 38c engaging upwardly bowed portion 18d of the septum and
forcing it downwardly from the position in Fig. 1A toward its downwardly curved, or concave, position illustrated in Fig. 1B. As this occurs rod 34 transmits the downwardly directed forces of cap 38 and septum 18 to force supplemental container 26 from its position friclionally held in sealing ring 18b. Supplemental container 26 then is shifted downwardly to the position illustrated in Fig. 1B, such that its open end 26c is exposed to the interior of container 26 and components 14, 30 (such as a diluent and lyophilate) may be mixed together by inversion of the mixing vial and gentle shaking to produce a combined mixture 42 within container 12 as shown in Fig. 1C.
After the components have been thoroughly mixed actuator cap 38 may be removed to expose septum 18 through which a needle may be inserted to withdraw a quantity of combined mixture 42.
The mixing container 12 and supplemental container 26 may be made of glass or other material acceptable for use in such situations, with a primary requirement being that they be liquid impermeable. The septum is composed of a flexible elastomeric material, such as rubber or an acceptable plastic. Holding member 22 may be made of a metal or plastic material capable of providing sufficient holding force to maintain a sealing condition between septum 18 and lip 12b of container 12. Cap 38 and safety member 40 may be made of any appropriate material, such as plastic or metal, capable of supporting the loads which may be imposed thereon and allowing removal from the combined assembly as illustrated. Rod 34 may be glass, plastic, or metal.
In assembling the mixing vial with the components held in the containers, a first component, such as the lyophilate 14 may be produced by an appropriate process within container 12 itself, if desired. Similarly, if the lyophilate is to be held in supplemental container 24 it also could serve as the vessel in which in the lyophilate is produced. It should be recognized that either component 14 or 30 may be placed in mixing container 12 and the other of such components placed in supplemental container 24 as most appropriate for the application at hand.
After the desired component has been placed in container 12, and the second component placed in supplemental container 26, rod 34 is placed in supplemental container 26, and the open end of container 26 is inserted into sealing ring 18b and frictionally held therein. Supplemental container 26 and septum 18 then are inserted into the mouth of container 12 as illustrated in Fig. 1A and holding member 22 is secured thereon. Safety member 40 and operating cap 38 then are attached as illustrated in Fig. 1A. The assembled apparatus of Fig. 1A provides excellent separation of the components for storage or transporting, and simple release for mixing.
Referring to Figs. 2A, 2B, a second embodiment is illustrated. Here a mixing vial, or apparatus, for storing and mixing first and second components is indicated generally at 44. It includes a mixing container 12 generally similar to that described above having the same configurations and portions which arc similarly numbered herein.
Mixing container 12 is adapted to hold one of the two components to be mixed, such as the lyophilate 14 indicated.
A flexible elastomeric septum 48 overlies and closes off the open end of container 12. A holding member 22 similar to that previously described above is secured over septum 48 to sealingly hold it on the top of container 12. Again holding member 22 has a central opening 22b which exposes the central portion of septum 48.
An actuator cap 38A generally similar to previously described cap 38 overlies the top of the container. Cap 38A has an upper, or top plate, portion 38a with a cylindrical depending skirt 38b. This cap does not have a depending protrusion on its underside as illustrated in Fig. 1 A. However, it is provided with radially inwardly protruding portions 38d which overlie the outer edges of holding member 22 to inhibit movement of cap 38A downwardly from the position illustrated in Fig. 2A.
A removable safety ring 40, as previously described above, is interposed between the lower end of cap 38A and shoulder 12d on the container to further assure that cap 38A is held in place in a raised position as illustrated in Fig. 2A.
A liquid impermeable supplemental container 52 is received in container 12 as illustrated in Fig. 2A. The supplemental container has a main body portion 52a which is substantially cylindrical in configuration with an open upper end surrounded by a radially outwardly projecting annular rim 52b. Rim 52b is sealingly captured between septum 48 and the upper rim 12b of container 12. Remainder portions of body 52a extend inwardly through neck 12a of container 12 with an open lower end portion 52c received within container 12. The open lower end 52c has a radially outwardly projecting annular rim 52d which provides a substantially continuous circular shoulder facing in the direction of rim 52b.
The supplemental, or inner, container may be made shorter than that shown in the drawings, such that it does not extend inwardly of container 12 a meaningful distance beyond the neck of container 12. Such construction would avoid the possibility that mixed materials may be trapped between the outer surface of the supplemental container and the inner wall of container 12 and not be available to be easily withdrawn.
A cap, or closure member, 56 is adapted to sealingly close the lower end 52c of container 52. Closure member 56 has a substantially planar body portion 56a and an
upwardly projecting cylindrical rim 56b. An annular shoulder 56c extends radially inwardly from the top portion of rim 56b and is positioned and configured to engage the upper shoulder on rim 52d at the lower end of container 52. The nm 56b of cap 56 may be made of elastomenc material and is sufficiently flexible, or resilient, that it may be slipped on to and releasably grip the lower end portion of container 52 to sealingly close the lower end of container 52. The gripping force of the cap, however, is yieldable such that the cap may be forced from its closure position as illustrated in Fig. 2B as will be described in greater detail below.
The lower end portion of container 52 and cap 56 have a smaller outer diameter than the inner diameter of neck 12a of container 12 so they can be inserted into container 12 during assembly.
An elongate rigid actuator rod 58 extends sealingly through an opening in septum 48 and into supplemental container 52. Rod 58 has a manually engagable head 60.
When rod 58 is in its at rest position as illustrated in Fig. 2A, it applies substantially no force against cap 56, and thus cap 56 is held in mated sealing engagement with the lower end of container 52 to hold a second component, such as diluent 30 therein. Rod 58 may be manually forced downwardly as illustrated in Fig. 2B to force cap 56 from the lower end of container 52 to release diluent 30 into container 12, such that it may be mixed with lyophilate 14 to provide a combined mixture indicated generally at 42.
To actuate rod 58 to open supplemental container 52 it is necessary to remove cap 38A and manually engage head 60 to press rod 58 downwardly. In an alternate embodiment which may lack radially inwardly directed protrusions 38d on cap 38A, safety member 40 may be removed, and cap 38A pressed downwardly toward septum 48 which would act to press rod 58 downwardly. However, regardless of which method is used, cap 38A must be removed to permit access of a needle to puncture septum 48 and withdraw a quantity of combined mixture 42 therefrom for use.
Upon assembly of the apparatus illustrated in Fig. 2A, a first of the components, be it lyophilate or diluent, is placed in container 12. If desired, previously known manufacturing processes can be used wherein liquid vaccine can be introduced into container 12 and lyophilized in place.
Next, supplemental container 52 has cap 56 attached thereto, the second component, such as diluent 30 shown herein, is placed in container 52, septum 48 is placed against rim 52b, and the combined assembly of the supplemental container 52, cap 56, septum 48, and holding member 22 are assembled onto the container 12 as illustrated, with rod 58 extending
through septum 48. Cap 38A and safety member 40 are applied and the container is ready for storage and shipment in the condition illustrated.
Another embodiment is illustrated Figs. 3A, 3B. Here a mixing vial, or apparatus, for storing and mixing first and second components is indicated generally at 66.
The apparatus includes a mixing container 12 substantially similar to that previously described above, with an overlying sealing elastomene septum 68 scalingly held at the open end of container 12 by a holding member 22 as previously described.
A liquid impermeable, substantially rigid supplemental container 72 having generally a test tube shape is held within container 12. Container 72 has a cylindrical major body portion 72a, a rounded closed lower end 72b, and a rim 72c surrounding the neck at its open mouth. A lower end portion of container 72 is somewhat necked down to provide a shoulder region 72d.
A yieldable biasing mechanism, in the form of a compression spring 76, bears at one end against the bottom, or lower end, 12e of container 12 and at its opposite end against shoulder region 72d of container 72. Spring 76 urges rim 72c of the supplemental container into sealing engagement with the inwardly facing surface of septum 68. In this position container 12 may hold one of the components to be mixed (shown here as diluent 30) and supplemental container 72 may hold the other of the components to be mixed (shown here as lyophilate 14).
An elongate rigid hollow rod 80 extends from a region outside septum 68, slidably and sealingly through an opening in septum 68, through supplemental container 72, and engages the lower end 72d. The outer end of rod 80 is secured to a head 82 which has a port 84 which communicates with the central lumen of rod 80.
A shorter needle 88 also extends sealingly and slidably through septum 68 and is secured to head 82. A second port 90 in head 82 communicates with the lumen of needle 88.
An overlying cap similar to those indicated in Figs. 1 A, 2A at 38, and 38A and an appropriate safety member as previously illustrated at 40 may be placed about head S2 and the upper portion of container 12 to seal such in a non-operating position for storage and transportation. However such additional elements have not been shown here for simplicity.
In its normal at rest state as shown in Fig. 3A, spring 76 holds rim 72c of supplemental container 72 in sealing engagement against the underside of septum 68. This effectively provides a sealed separation between components 14, 30. When it is desired to mix components 14 and 30 a user manually presses head 82 toward septum 68 as shown in Fig. 3B. This manual force is transmitted through rod 80 to supplemental container 72
which compresses spring 76 and forces rim 72c from septum 68, thus opening the mouth of supplemental container 72 to the interior of container 12. The containers then may be inverted as illustrated in Fig. 3B to allow components 14, 30 to be mixed by gentle shaking of the apparatus. The friction forces acting between rod 80 and needle 88 and the material of septum 68 should be sufficient to hold the operator head in its collapsed position as illustrated in Fig. 3B against the biasing force of spring 76, such that the mouth of supplemental container 72 would remain open. After the components have been mixed into a combined mixture 42 appropriate auxiliary apparatus may be connected to ports 84, 90 to withdraw a quantity of the combined mixture for use.
An alternate embodiment of the apparatus shown in Figs. 3A and 3B, although not shown in the drawings, could include a solid rod 80 without a lumen, or bore, extending therethrough and port 84 would not be included. Port 90 could be a standard luer type adapter to which a syringe or other apparatus could be attached to withdraw mixed materials through needle 88. The standard luer type adapter would be capped or plugged for protection of the contents in the mixing apparatus until such time as they are to be withdrawn.
It should be recognized that a standard luer type adapter also could be used with other embodiments of the invention described herein to facilitate withdrawal of mixed materials from the apparatus.
Figs. 4A, 4B, 4C illustrate yet another embodiment. This includes a mixing vial, or apparatus, 94 for holding, storing, and mixing first and second components. The apparatus includes a mixing container 12 generally as described above. A flexible elastomeric septum 92 is held in sealing engagement over the open end of container 12 by a holding member 22 as previously described. An actuator cap 38 with substantially planar top portion 38a, depending skirt 38b, and protrusion 38c, as previously described in regard to Fig. 1A, overlies septum 92. A safety member 40 as previously described is interposed between cap 38 and shoulder 12d on container 12 to prevent shifting of cap 38 from its first non-operating position as illustrated in Fig. 4A until desired.
A liquid impermeable supplemental container 96 is received in mixing container 12. The supplemental container illustrated here has an open first end facing septum 92 with a radially outwardly extending annular rim 96a sealingly interposed between septum 92 and rim 12b of container 12. Supplemental container 96 is formed of a liquid impermeable material such as a foil-polymer composite material which has a rupturable lower end portion 96b facing into container 12 opposite its open first end. An actuator, or agitator, ball, or member, 100 rests loosely in a quantity of one of the mixture components which
substantially fills supplemental container 96. In this instance the component material held in the supplemental container is lyophilatc 14, and liquid diluent 30 is held segregated therefrom in container 12.
To produce mixing of components 14, 30 a user removes safety member 40 permitting cap 38 to be pressed downwardly, such that protrusion 38c engages the top of flexible elastomeric septum 92 and forces it downwardly as illustrated in Fig. 4B. This transmits the manual force applied to cap 38 through septum 92, to ball 100 and component material 14 held in supplemental container 96. The transmission of such force to the supplemental container causes the rupturable inwardly directed portion of container 96 to break, with a breach 96c therein allowing component material 14 and ball 100 to drop into container 12 as illustrated in Figs. 4B and 4C. Container 12 then may be shaken with ball 100 assisting in the mixing of components 14, 30 to form combined mixture 42. Following mixing a needle may be inserted through septum 92 to withdraw a quantity of the combined mixture for use.
Figs. 8A, 8B, 8C illustrate yet another embodiment. The primary components of this embodiment are substantially similar to those described above in regard to Figs. 4A-4C, and thus are given similar numbers.
In the embodiment illustrated in Figs. 8A-8C the component material to be mixed with the diluent indicated at 14A is a substantially solid disc-shaped tablet. It is held in a liquid impermeable supplemental container 97 closely adjacent the underside of septum 92. The radially outwardly extending annular rim portion 97a of container 97 is sealingly interposed between septum 92 and rim 12b of container 12. The lower portion 97b of the supplemental container supports tablet 14A. Again, the supplemental container 97 is formed of a liquid impermeable material, such as a foil-polymer composite material or other appropriate material, which has a rupturable portion facing into container 12.
To produce mixing of components 14A and 30 a user removes safety member 40, permitting cap 38 to be pressed downwardly, such that protrusion 38c engages the top of flexible septum 92 and forces it downwardly as illustrated in Fig. SB. This transmits manual force to tablet 14A which causes the rupturable inwardly directed portion of container 97 to break, with a breach 97c therein allowing component material 14A to drop into container 12 as illustrated in Fig. 8B. The container then may be shaken to mix components 14A, 30 to form combined mixture 42. Removal of cap 38 following mixing allows a needle to be inserted through septum 92 to withdraw a quantity of combined mixture therefrom.
Referring to Figs. 5A, 5B, yet another embodiment is illustrated. Here a mixing vial, or apparatus, for storing and mixing first and second eomponcnts is indicated generally at 104. It includes a mixing container 12 similar to that previously described with an overlying flexible elastomerie septum 106 sealingly held to the open mouth end of container 12 by holding member 22 as previously described. The central portion 106a of septum 106 is initially bowed upwardly in a convex configuration as illustrated in Fig. 5A and may be manually forced to a downwardly curved, or concave, configuration as illustrated in Fig. 5B.
A cap 38B somewhat similar to that previously described at 38A overlies septum 106 with inwardly directed projections 38d to inhibit movement of cap 38B toward septum 106. A safety member 40 again is interposed between cap 38B and shoulder 12d of container 12.
Alternately, a cap similar to that indicated at 38 in Fig. 1A with a protrusion 38c on its underside aligned with central portion 106a of septum 106 could be used. Such cap 38 would not have projections 38d as illustrated in Fig. 5A and could act as an actuator member to be pressed against by a user to urge central portion 106a of septum \06 between its upwardly curved positions illustrated in Fig. 5A and its downwardly curved position as illustrated in Fig. 5B.
A liquid impermeable supplemental container 110 is received in container 12. The open end of container 110 adjacent septum 106 has a radially projecting annular rim 110a sealingly captured between septum 106 and rim 12b of container 12. The opposite end 110b of container 110 extends into container 12 and has a rupturable portion which may be broken, with the breach therein opening into container 12.
The supplemental, or inner, container may be made shorter than that shown in the drawings, such that it does not extend inwardly of container 12 a meaningful distance beyond the neck of container 12. Such construction would avoid the possibility that mixed materials may be trapped between the outer surface of the supplemental container and the inner wall of container 12 and not be available to be easily withdrawn.
An elongate rigid actuator rod 112 extends between central portion 106a of the septum and lower end portion 110b of the supplemental container. In its normally at rest position the rod is held as illustrated in Fig. 5A.
Upon manual force being applied to the central portion 106a of the septum inwardly toward the container, such manual force is transmitted through rod 112 to the lower end portion 110b of the supplemental container causing the rupturable portion of the supplemental container to break to produce a breach 110c. In the illustrated embodiment lyophilate 14 is held in container 14 segregated from liquid diluent 30 in supplemental
container 110. Upon breaching of container 110 as illustrated in Fig. 5B, the diluent 30 and rod 112 drop into container 12 to permit shaking of the container with the rod 112 assisting in agitating and mixing the components to form combined mixture 42 therein.
Again, a quantity of the combined mixture may be withdrawn by a needle inserted through septum 106 following removal of cap 38B.
Another embodiment is illustrated in Figs. 6A, 6B wherein a mixing vial, or apparatus, for storing and mixing first and second components is indicated generally at 116. It includes a mixing container 12 as previously described, having an overlying flexible elastomeric septum 118 sealingly held at its open end by holding member 22 as previously described.
A supplemental container 120 extends into container 12 and has a radially projecting annular rim 120a at its open end sealingly held between septum 118 and rim 12b of container 12. The lower end portion 120b of supplemental container 120 extends into and is directed inwardly of container 12.
The supplemental, or inner, container may be made shorter than that shown in the drawings, such that it does not extend inwardly of container 12 a meaningful distance beyond the neck of container 12. Such construction would avoid the possibility that mixed materials may be trapped between the outer surface of the supplemental container and the inner wall of container 12 and not be available to be easily withdrawn.
An elongate rigid rod 122 having a head 124 extends sealingly through an opening in septum 118 with the major portion of the rod received in supplemental container 120. An overlying cap similar to that described earlier at 38A and a safety member 40 as previously described are assembled as illustrated in Fig. 6A.
Upon removal of cap 38A a user may manually engage head 124 and force rod 122 inwardly from a non-operating first position as illustrated in Fig. 6A to an operating, or breaching, position illustrated in Fig. 6B. This causes force to be transmitted to the supplemental container 120 to breach a rupturable portion therein as shown at 120c in Fig. 6B which releases a component held in the supplemental container into container 12. In this case lyophilate 14 is held in container 12 and diluent 30 is held in supplemental container 120. These are mixed by shaking the container to form a combined mixture 42 illustrated in Fig. 6B.
As with all of the embodiments described herein, it should be recognized that generally either one of the components may be held in the mixing container and the other component held in the supplemental container as desired.
Referring to Figs. 7A, 7B, 7C, a further embodiment is illustrated. In this embodiment a mixing vial, or apparatus, for storing and mixing first and second components is indicated generally at 130. It includes an elongate outer mixing container 132 and an elongate inner, or supplemental, container 134 received in container 132.
Mixing container 132 has substantially cylindrical upper and lower end portions 132a, 132b, respectively, which are connected by a flexible corrugated, or bellows shaped, intermediate portion 132c. The operation of flexible intermediate portion 132c will be described in greater detail below.
The lower end of container 132 is closed by a bottom wall 132d, and its upper end is open, with a radially projecting lip, rim, or shoulder 132e. A flexible elastomeric septum 136 is sealingly attached to the open upper end of container 132 by a holding member 138 having a substantially planar upper portion 138a, a cylindrical depending skirt 138b, and a radially inwardly projecting rim 138c which engages rim 132e on container 132 to sealingly secure septum 136 to the top of container 132. A central opening 138d provides access to septum 136 through which a needle many be inserted into container 132 to withdraw materials therefrom.
Supplemental container 134 comprises an elongate ampoule which has sufficient length that its lower end rests on bottom wall 132 and its upper end extends into upper portion 132a of container 132. The container 134 is made of a frangible material, such as glass, having a hollow portion 134a which is connected to a solid portion 134b through a weakened intermediate section 134c.
In use, one of the components to be mixed, is held in container 132 (here diluent 30) and the other component to be mixed (here lyophilate 14) is held in the hollow portion 134a of supplemental container 134. The material of which supplemental container 134 is made is liquid impermeable, and thus the two components are segregated from each other during storing and handling in the manner illustrated in Fig. 7A.
As previously mentioned, intermediate portion 132c of container 132 is flexible. In its normally at rest position container 132 assumes a desired position with its upper and lower portions 132a, 132b disposed in a selected angular relation to each other. In the illustrated embodiment the angular relation is such that the two portions, or sections, 132a, 132b, are substantially aligned longitudinally of the container. However, other angular dispositions may be chosen as desired.
The flexible intermediate region 132c permits flexing, or bending, of the upper and lower portions of container 134 relative to each other as generally illustrated in Fig. 7B. As the upper and lower portions of container 132 are bent relative to each other as illustrated in
Fig. 7B the lower end of supplemental container, or ampoule, 134 is held against a sidewall of the lower portion of the container 132a and the upper end is forced to the side in the direction of arrow 140, with an intermediate region of the container bearing against an intermediate portion of the supplemental container which causes it to break at weakened section 134c as illustrated in Fig. 7C. When the supplemental container breaks as illustrated the component held within the supplemental container is free to mix with the component previously held segregated therefrom in container 132 such that they mix to form a combined mixture 42.
A needle then may be inserted through septum 136 to withdraw a quantity of the combined mixture therefrom.
Referring to Figs. 9, 10, 11A, 11B, and 11C, a further embodiment is illustrated. Here a mixing vial, or apparatus, for storing and mixing first and second components is indicated generally at 160. It includes an outer mixing container 12 generally similar to that described above having the same general configurations and portions, which are similarly numbered herein.
Mixing container 12 is adapted to hold one of the two components to be mixed, such as the lyophilate 14 indicated.
Referring to Fig. 10 in which the individual components are shown in exploded view, it will be seen that a liquid impermeable supplemental, or inner, container 162 having a generally test tube shape is provided. Supplemental container 162 generally has a cylindrical sidewall 162a with a closed lower end 162b, an open upper end 162c, and a neck portion 162d adjacent open end 162c.
Underlying container 162 in Fig. 10 is an inner container carrier 166 which has a substantially cup shaped lower end portion 166a into which the lower end portion 162b of container 162 may be press fit to frictionally hold container 162 in carrier 166.
Carrier 166 may be made of a plastic material having a plurality of elongate upwardly projecting holding fingers 166b which, when free of any encumbrance, are yieldably biased outwardly and assume an outwardly diverging configuration extending upwardly from lower portion 166a, as seen in Fig. 10.
The overall length of carrier 166 is somewhat shorter than the length of inner container, 162, such that when the inner container 162 is held in carrier 166 (as possibly best illustrated in Fig. 11B) the upper neck portion of container 162 extends above the upper ends of fingers 166b.
Still referring to Fig. 10, the mixing vial assembly further includes a somewhat hat shaped elastomeric cap 170. Cap 170 as seen in Figs. 10, 11A, and 11C has a central
inverted cup shaped portion 170a having a cylindrical sidewall 170b and a substantially Hat top portion 170c. A lower annular rim 170d extends circumferentially about and radially outwardly from the bottom of sidewall 170b. A cylindrical pocket 170e is formed in the under, or inner, portion of cap 170. The cap may be formed of suitable rubber or flexible plastic material.
As possibly best seen in Figs. 11A - 11C rim 170d is configured to rest on and sealingly engage the upper surface of annular rim, or lip, 12b adjacent open end 12c of mixing container 12. Cap 170 acts both as a sealing septum and a portion of the operator mechanism as will be described in detail below.
Cap 170 is held in sealing engagement against the annular rim 12b of the mixing container by a holding member, or ring, 174. The holding member, or ring, 174 may be a metallic ring which is slipped down and over rim 170d of cap 170 and annular rim 12b of mixing container 12 and then has its upper and lower rims 174a, 174b crimped inwardly about the upper surface of rim 170d and the lower surface of annular rim 12b to press rim 170d into tight sealing engagement with rim 12b.
A tear-off crimp ring, or member, 178 is configured to fit over upper portion 170a of cap 170 as will be described in greater detail below. Crimp ring 178 has a cylindrical sidewall 178a and a top wall 178b. Top wall 178b is cut through in an incomplete circle indicated generally at 178c leaving a center tab portion 178d attached to remainder portions thereof by a segment 178e. Sidewall 178a is vertically scored, as indicated generally by the two dotted lines 178f, such that tab portion 178d may be lifted from remainder portions of the ring, pulled to the left about segment 178e, and as it is pulled further to the left in Fig. 10 pulls apart scored portions 178f allowing the upper crimp ring to be removed from cap 170 when desired.
In the assembled configuration, as shown in Fig. 11A, upper crimp ring 178 is fit over upper section 170a of cap 170 and a radially inwardly directed circumferential crease 178g is formed fully about sidewall 178a.
In assembled configuration mixing vial 160 is generally as illustrated in Figs. 9 and 11A. Mixing container 12 has lyophilate 14 therein. The inner container 162 has liquid, or diluent, 30 placed therein, and the upper neck portion 162d of inner container 162 is inserted into the pocket 170e in the under side of cap 170, as illustrated in Fig. 11 A. Carrier 166 is press fit onto the bottom of inner container 162 with its elongate fingers 166b extending upwardly along the sidewall 162a of container 162. Multiple fingers 166b thus are arrayed circumferentially about container 162.
Upper crimp ring 178 without crease 178g therein is applied over cap 170 following insertion of inner container 162 into pocket 170e of the cap. After application of the upper crimp ring to the cap crease 178g is formed therein which provides a radially inwardly directed force to increase the frictional grip of cap 170 on the upper neck portion 162d of inner container 162. This acts as a sealing mechanism holding the supplemental container in sealing engagement. This is to assure that the inner vial will be tightly sealed to prevent leakage of moisture from the diluent to the lyophilate during transport and storage. The sidewall 178a of the crimp ring also acts as a holding portion to inhibit flexing of the cap inwardly until ring 178 is removed.
Cap 170 is seated against the upper rim 12b of container 12 with carrier 166 and container 162 extending downwardly through the neck 12a of container 12 into the interior thereof. Holding ring 174 is crimped onto the engaging rims of cap 170 and container 12 as illustrated in Fig.l 1A to sealingly hold them together. As best seen in Fig. 11A, in the initially assembled state fingers 166b are held by neck 12a closely adjacent sidewall 162a, in what is referred to herein as a non-deployed position.
To actuate the mixing vial illustrated in Figs. 9 - 11C, the user lifts tab 178d on the upper crimp ring and tears the upper crimp ring apart so that it may be removed from the assembly. Following removal of the upper crimp ring as shown in Fig. 11B, the elastomeric cap 170 may be manually depressed, or flexed, inwardly toward the mixing container, by the user, which forces inner container 162 and carrier 166 downwardly into the inner chamber of mixing container 12 in the direction of arrow 182. Since upper crimp ring 178 has been removed the frictional holding force of cap 170 on inner container 162 has been reduced permitting release of the inner container from the cap. Thus a manually operable release mechanism is provided.
As illustrated in Fig. 11B, as the fingers 166b of carrier 166 pass below neck 12a of container 12 they expand, or spring, outwardly into a deployed position against the inner walls of container 12.
To mix the liquid and lyophilate, the entire assembly is inverted as illustrated in Fig. 11C such that liquid may flow out of inner container 162 to mix with the lyophilate 14. Fingers 166b engage the inner portions of shoulder 12d of container 12 to act as restraining mechanism and prevent the inner vial from falling back in a direction opposite arrow 182 fully into the neck of the mixing container. The fingers prevent the inner container 162 from returning to sealing engagement with cap 170. As seen in Fig. 11C, a space is provided between the neck 12a of the mixing container and the neck portion 162d of inner container 162 allowing movement of fluid and lyophilate therebetween.
The mixing vial 160 is not necessarily held in its fully inverted position as illustrated in Fig.11C when shaken to mix the materials. Instead, the mixing vial may be turned on its side and shaken. Regardless of the position in which the mixing vial is oriented during shaking to mix the materials within the container, the carrier 166 and its outwardly projecting fingers 166b inhibit direct contact between the inner container 162 and mixing container 12 to reduce potential breakage or chipping during mixing.
Once the material has been fully mixed the mixing vial may be inverted as illustrated in Fig. 11C. A needle or prong may be inserted by piercing the elastomeric cap 170, which serves as a septum, to withdraw mixed material therefrom.
Referring to Figs. 12A, 12B, 12C, yet another embodiment of the invention is illustrated. At 190 is indicated generally a mixing vial, or apparatus, according to this embodiment of the invention. It includes a mixing container 12 generally similar to that described previously having similar configurations and portions which are similarly numbered herein. Mixing container 12 is adapted to hold one of the two components to be mixed, such as the lyophilate 14 indicated.
Resting sealingly atop annular rim, or lip, 12b of container 12 is a hat shaped cap 194 having somewhat the same configuration as illustrated and described previously for cap 170. This cap differs in that it has a lower portion 194a which extends a short distance downwardly into the neck 12a of the container and has a pair of vertically spaced apart annular groves, or channels, 194b, 194c, defined therein.
Cap 194 has an annular rim 194d which is sealingly held against the upper rim of container 12 by a holding member, or rim, 174 as previously described regarding Figs. 9-11C.
A generally cylindrical pusher ring, or thimble, also referred to as an operator member, 198 made of a substantially rigid material, such as hardened plastic, is configured to fit slidably within the interior of cap 194 as illustrated. Ring 198 has a projecting annular rim 198a at its upper end which is held in annular groove 194b. The lower end of ring 198 is spaced a short distance above annular groove 194c in cap 194.
A liquid impermeable inner, or supplemental, container 200 has a cylindrical sidewall 200a, a bottom 200b, and an upper end, or neck, 200c having a radially outwardly projecting annular rim 200d which is received in annular grove 194c in cap 194. A carrier 204 similar to that previously described at 166, has a substantially cup shaped cylindrical lower portion 204a and a plurality of elongate upwardly projecting elongate fingers 204b.
Inner container 200 is press fit into the lower cup shaped portion 204a of carrier 204 such that the two move together in the mixing vial. Fingers 204b have such length that they
stop short of the underside of cap 194 when inner container 200 is held as illustrated in Fig. 12A.
Supplemental, or inner, container 200 is adapted to hold the second mixing component, such as liquid, or diluent, 30 separated from the first-mentioned component 14 held in container 12.
An actuator cap 208 having substantially planar outer portion, or top, 208a and a depending cylindrical skirt 208b is shiftable between a non-operating position as illustrated in Fig. 12A and an operating position as illustrated in Fig. 12B.
A safety member, or ring, 210 is interposed between the lower end of skirt portion 208b and shoulder 12d on container 12. In the safety position for member 210 illustrated in Fig. 12A, cap 208 is prevented from shifting downwardly from its non-operating position as illustrated. However, the safety member 210 may be removed (also referred to herein as removed to a release position) when it is desired to mix components in the containers. Upon removal of safety member 210 actuator member 208 may be shifted manually downwardly to its operating position as illustrated in 12B.
As the actuator cap 208 is pressed downwardly, the upper portion of cap 194, due to its being constructed of an elastomeric material, is flexed downwardly as shown in Fig. 12B to shift ring 198 downwardly which presses inner container 200 downwardly to release it from its position held in grove 194c so that it falls into mixing container 12 as illustrated in Fig. 12B. Elongate fingers 204b on carrier 204 are yieldably biased outwardly so that they will spring outwardly into deployed positions as shown in Fig. 12B. Upon inversion of mixing vial as illustrated in Fig. 12C to mix the liquid and the lyophilate, fingers 204b engage inner portions of shoulder 12d of the mixing container to inhibit return of container 200 to engagement with the sealing mechanism of cap 194 to permit mixing of the lyophilate and liquid. Again, a needle or probe may be inserted through the top portion of cap 194 to withdraw mixed solution from the mixing vial.
Each of the embodiments illustrated provides apparatus in which two components may be stored and transported in segregated separate compartments in one compact sterile package. Reconstitution, or mixing, of the components is easily accomplished by simple manual manipulation of the apparatus to allow mixing the components within the package itself. The reconstituted, or mixed, components can be used with aerosol devices, jet injectors that draw mixture from a vial, conventional needles and syringes which withdraw material from the containers, or other devices.
The mixing vial system of the invention allows the use of a standard outer container of glass or other appropriate material and various types of supplementary containers to
create separate liquid impermeable inner storage compartments. The separate components are segregated by impermeable barriers. When mixing, or reconstitution, is desired a guard, or safety, feature is disabled, or removed, and simple hand motion serves to produce opening of one of the containers relative to the other to permit mixing within the sterile environment of the container.
The invention as set out herein provides simplicity, in that multiple vials are not needed for multiple components which need to be mixed. No syringes or needles are required for transferring components from one container to another for mixing, as has been required in some prior systems. A simple manual motion is capable of initiating a mixing sequence.
Further, pre-measured quantities of components may be packaged in the mixing container and supplemental container whereby the components are properly matched both as to the component materials themselves and the quantities to be mixed. This prevents mistakes in both materials and proportions upon mixing. Further the system as disclosed herein provides a very rapid means for reconstituting, or mixing, components in a safe manner.
The system permits use of a mixing vial which is substantially similar in size and shape to current vials used for storing and transporting medical components and is scalable from single to multi-dose sizes.
Where the lyophilate may need to be kept cool to retain its viability, such can be accomplished more easily by being packaged in the same container with a mass of cold diluent while maintaining the two segregated until such time as mixing is desired.
In several of the embodiments illustrated, the mixing container and supplemental container may be made of glass or other liquid impermeable material commonly acceptable in medical uses. Where rupturable materials are required, such materials may include a foil-polymer composite container or other liquid impermeable materials which will provide sufficient strength to maintain separation between the component parts during storing and travel, yet which may be ruptured to provide mixing of the component parts by manual actuation as described previously. The septurns disclosed may be molded of a two-part silicon rubber, though other types of rubber or appropriate elastomeric materials may be used as appropriate for the components and conditions under which the container is to be used. The actuating rods and balls described may be made of glass, stainless steel, or other materials appropriate for the components to be mixed and to maintain sterile conditions.
While several embodiments have been disclosed herein, it should be apparent to those skilled in the art that variations and modifications are possible without departing from the spirit of the invention as set out in the claims following.
