Description

Shape-adapted multipurpose peritoneal bag

Technical Field

The utility model belongs to the technical field of medical treatment operation seam is with device, concretely relates to shape-adapted multipurpose is for abdominal membrane bag.

Background

ACS (abdominal compartment syndrome) is a series of pathophysiological changes caused by the acute increase of intra-abdominal pressure due to various reasons, which relate to cardiovascular, lung and kidney, can affect organ blood flow, central nervous system and wound healing, endanger life, and clinically need to open abdomen and reduce pressure to treat ACS.

After decompression of the abdominal cavity, the abdominal cavity is difficult to close without tension or unable to close due to retroperitoneal hematoma, visceral edema, severe abdominal infection, or hemostatic packing with abdominal gauze, and although ACS is avoided by opening the abdominal cavity, intestinal fistula and bulging of organs in the abdominal cavity are likely to occur.

Abdominal trauma in battlefield environments is as high as 15%, with conservative estimates of abdominal wall defects of 9%. Meanwhile, the front-line hospital has a large number of emergency intra-abdominal hemostasis or injured organ resection operations to save lives of wounded persons. When the war damage of the abdominal wall occurs, the wound is irregular, and the first-stage suture closing of the abdominal wall cannot be completed under high pressure, high pollution and the like in the wound and the abdominal cavity. Traditional tamponade or compression dressings may cause loosening of the tampon or dressing during the hospital procedure after transport, causing reopening of the abdominal cavity, leading to increased risk of infection and organ damage within the abdominal cavity. And even threatens lives of wounded persons. Modern abdominal surgery requires to follow the principle of injury control for abdominal trauma, namely, the abdominal drainage is fully performed after the treatment of main injured organs, excessive treatment is not required, and forced closing of the abdomen is not required, so that the occurrence of postoperative ACS is prevented, the control of the whole body condition is facilitated, and a foundation is laid for later-stage treatment.

The Bogota bag is a device which is sewn manually according to actual requirements in clinic, usually medical polypropylene is used as a material, and the Bogota bag can be used for closing an abdominal incision to simulate a natural abdominal cavity in an abdominal cavity compartment syndrome (ACS) operation, so that continuous decompression and protection of organs in the abdominal cavity can be realized. The Bogota bag is also convenient for operation, convenient for debridement after repeated operation and adjustment of various drainage tubes in the abdominal cavity, thereby being widely applied.

However, the existing Bogota bags have the following drawbacks:

firstly, the predicted volume of the Bogota bag before operation is insufficient, which causes poor pressure reduction effect or disease deterioration, the abdominal pressure is continuously increased, the operation is required again, and the Bogota bag with larger volume is replaced.

Secondly, the Bogota bag is sewed on the incision peritoneum and subcutaneous tissue in a sewing way, and the operation is time-consuming and labor-consuming.

Third, when the Bogota bag is used for more than one week, the edges and tissues of the bag are torn off and the abdominal contents are herniated due to the tension of the incision and the chronic cutting of the suture. The Bogota bag loses the original function, sometimes needs to be replaced by another operation, increases the times of anesthesia operation and the risk of complication occurrence, and is time-consuming and labor-consuming after the operation or the operations.

And fourthly, the Bogota bags are not suitable for abdominal wall war injuries with different sizes and shapes.

Whether ACS in peace period or emergency abdominal wall damage rescue in wartime or emergency abdominal operation faces difficulty in closing abdomen, so that a temporary abdomen-replacing film bag (film) which is suitable for different shapes and sizes, convenient and quick to install, safe and reliable is urgently needed, and the purpose of temporarily closing abdomen is achieved.
