SELF RETAINING DRAIN
|Abstract||A device is a self retaining drain which is used after abdominal or thoracic surgeries. This tube does not require stitches to fix it to the abdominal or chest wall and prevents peridrain leakage of fluid from abdominal or chest cavity. This device retains in place with the help of a balloon 3 which is inflated with a channel 4. This tube is fixed by a disc 6 from outside which is hold in place by a belt 7. The inflated balloon 3 prevents pulling out of the drain and leakage of fluid from peridrain area.|

SELF RETAINING DRAIN
This invention is related to improvement in the drain that is used in the patient after the abdominal or thoracic surgeries.
Simple tube drain is being used for past many years in the patients after abdominal or thoracic surgeries. This simple tube drains the fluid from the abdominal or thoracic cavity which otherwise can collect in the cavity and may be hazardous to the patient. This tube is connected to a bag outside in which the fluid is collected.
This conventional tube requires fixation with the skin with the help of a stitch which prevents pulling out of the drain from the abdomen or thorax. The problem with the stitch is that it causes pain
and discomfort to the patient in the postoperative period and some times may cut though the skin and drain comes out of the cavity and it creates many problems. Usually these drains are removed after 5-7 days when the drain output is minimal. Removal of the drain also causes pain because of the stitches.
Sometimes this drain has to be kept for longer than expected time for some reasons like high output in the drain or leak from the bowel anastomosis in which case this drain is very important in draining the contaminated fluid from the abdominal cavity. In these types of cases the stitch with which the drain is fixed cut through within 8-10 days and creates a big wound around the tube. Second fixation with the stitch can be done but it again causes the same problem. When the gap around the drain increases, it starts leaking of the abdominal or thoracic contents surrounding the tube which soils the dressing and cloths of the patient and is very uncomfortable to the patient. Leakage of the fluid around the drain causes skin irritation and pain. This may be a source of infection at the drain site.
These problems are overcome by the present invention, which provides a self retaining drain.
Brief description of the drawing:
FIG: 1 shows the self retaining drain with deflated balloon, movable disc and small belt.
FIG: 2 shows drain with balloon inflated and disc and belt in place.
FIG: 3 shows the application of such a drain in the body.
Detailed description of the drawing:
Referring to Fig. 1 can be seen that the self retaining drain according to this invention comprises a tube 1 which is made up of biologically inert material having multiple holes 2 at one end which drains fluid from the cavity. Just distal to the last hole there is an inflatable balloon 3 which is connected with a channel 4 from where air or sterile water can be injected which passes through the passage 5 and balloon can be inflated. This channel 4 has got one way valve which prevents leakage of air or water from the bulb. This balloon can be deflated when drain is to be removed by aspirating the air or water though the one way valve of channel 4. The movable disc 6 is placed distal to the balloon which can be fixed with a small belt 7 which can be adjusted according to the need. The serrations 8 in the tube help in better fixation of the belt and prevent its slippage.
Fig. 2 shows the position of the disc 6 and belt 7 on the tubes 1 which are placed distal to the balloon 3 and inflation of the balloon from channel 4.
Fig. 3 shows self retaining drain in operation. It can be seen that when the balloon 3 is inflated, it prevents the tube coming out of the abdominal or chest cavity. The inflated balloon 3 retains the tube in place near the abdominal wall 9. Disc 6 holds the tube in place from outside and prevents any in-out movement. The belt 7 fixes the disc 6 at its place. The other end of the drain is connected to a bag to collect fluid. The balloon 3 when inflated near the inner abdominal wall, it prevents any fluid leakage around the tube. As seen by the arrow, there is no space between the balloon and the inner abdominal wall which helps in prevention of fluid leakage from the abdominal or
chest cavity 10.
As seen in Fig. 3 that this device needs no stitches to fix it to the
abdominal wall or chest wall and it also prevents the peridrain leakage of the body fluid.
1. A self retaining drain comprising a tube with multiple holes at one end and an inflatable balloon which can be inflated through a channel, which prevents the tube from coming out of the body and a movable disc which fixes the drain from outside. The disc is fixed by the belt. The other end of the drain is connected to a bag to collect fluid drains from the body cavity.
2. The self retaining drain in claim 1 wherein the balloon can be inflated with saline or air.
3. The self retaining drain in claim 1 wherein the serrations may be straight or in cress-cross manner.
4. The self retaining drain in claim 1 wherein the tube is made up of PVC.
5. The self retaining drain in claim 1 wherein the channel to inflate the balloon is having one way valve mechanism.
