Full Text	This invention relates to a needle applicator particularly but not exclusively for injecting medicines to and withdrawing fluids from human or animal body. Conventionally, medical practioners make use of hand held syringe and needle systems for withdrawal of fluids from or for inejction of drugs and the like into human or animal bodies. Problems or drawbacks associated with the use of hand held needle-syringe assembly are inability to reach the desired spot, wobbling motion of the needle top and resultant puncturing of nerve endings and other vital parts of the body. The present invention relate to a needle applicator which avoids the above recited drawbacks of the hand held syringe-needle assembly. This invention is hereinafter described with reference to an applicator suitable for injecting or withdrawing fluid from the lumbar spinal column of human body. The applicator consists of a base member body provided with an outwardly extending hollow projection on one side. The other side of the base member is contoured to snuggly adapt to the lumbar area of human body. This side of the base member has an opening to facilitate entry of the needle therethrough to the human body. the hollow projection fo the base member houses a rotable knob which is graduated and is threadedly housed within the base member. This rotatable knob has a needle holder which • may be a screw type needle holder. A guide pin is provided on the needle holder for guiding the injection needle whenever necessary. This guide pin is associated with means for guiding and locking the needle held in the needle holder. It consists of a member vertically mounted on the base member. This member has a linear slot connected to the needle holder through the guide pin. The guide pin may be operated to loosen or lock the needle held by the needle holder through the linear slot.

This invention relates to a needle applicator particularly but not exclusively for injecting medicines to and withdrawing fluids from human or animal body.
Conventionally, medical practioners make use of hand held syringe and needle systems for withdrawal of fluids from or for inejction of drugs and the like into human or animal bodies. Problems or drawbacks associated with the use of hand held needle-syringe assembly are inability to reach the desired spot, wobbling motion of the needle top and resultant puncturing of nerve endings and other vital parts of the body.
The present invention relate to a needle applicator which avoids the above recited drawbacks of the hand held syringe-needle assembly. This invention is hereinafter described with reference to an applicator suitable for injecting or withdrawing fluid from the lumbar spinal column of human body. The applicator consists of a base member body provided with an outwardly extending hollow projection on one side. The other side of the base member is contoured to snuggly adapt to the lumbar area of human body. This side of the base member has an opening to facilitate entry of the needle therethrough to the human body. the hollow projection fo the base member houses a rotable knob which is graduated and is threadedly housed within the base member. This rotatable knob has a needle holder which • may be a screw type needle holder. A guide pin is provided on

the needle holder for guiding the injection needle whenever necessary. This guide pin is associated with means for guiding and locking the needle held in the needle holder. It consists of a member vertically mounted on the base member. This member has a linear slot connected to the needle holder through the guide pin. The guide pin may be operated to loosen or lock the needle held by the needle holder through the linear slot. The forward and backward movement of the needle holder and the needle housed therein are controlled by the guiding pin and the linear slot. The base member may be circular in shape. The rotatable knob is mounted to the base member by means such as circlips.
This invention relates to a needle applicator which comprises a base member, one side thereof being contoured, the side opposed thereto having an outwardly extending hollow projection terminating in an opening on the contoured side of said base member, and housing a rotable knob within, a needle holder assembly coaxially disposed within said rotatable knob, and extending vertically therefrom and a guiding and locking means for guiding and locking a needle housed with said needle holder assembly.
This invention will now be described with reference to the single figure in the accompanying drawings which is a • sectional view of the needle applicator.

The base member is indicated by reference letter (a). Rotatable knob is representated by reference letter (b). Letter c indicates the needle holder assembly which is partially housed within the rotatable knob. The grinding and locking means for grinding and locking the needle represented by (e) is shown by (d) and (f). Screw which mounts the looking means on to the base nmember is shown by letter (g) while the circlip which mounts the rotatable knob within the projection is shown by h.
The needle and part of the syringe may be inserted into the needle holder such that the free end of the needle projects out through the opening provided on the base member. By rotating the knob clockwise or anticlockwise, the needle may be advanced or retracted. After a desired positioning is reached screw (f) of the guiding and locking system is tightened to lock the needle in that position. This prevents wobbling of the needle during operation.
The linear slot provided on the looking and guiding means facilitates easy manoeuvreing of the needle as desired depending upon the operation required. The parts may be easily dismounted for sterilization and reassembly. The parts may be made of Teflon or stainless steel.

Though this invention is described hereinabove, with a specific embodiments, alterations and variations known to persons skilled in the art are within its scope and that of the appended claims.
