AI Technical Summary

Technical Problem

During peritoneal drainage, body fluids easily seep out between the drainage tube and the abdominal wall hole wall, causing contamination, which is difficult to effectively prevent with existing technology.

Method used

A peritoneal drainage tube device was designed, which included a collecting bag, a guide tube, a fixing plate, a sealing mechanism, and a tapered knob. The device was fixed to the skin via an adhesive layer, and the sealing mechanism and the tapered knob were used to compress the drainage tube to prevent body fluid leakage and sliding of the collecting bag.

Benefits of technology

Effectively prevent body fluids from contaminating the environment, ensure the sealing between the drainage tube and the collection bag, avoid liquid leakage, and reduce the risk of unplanned extubation.

Abstract

The utility model discloses an abdominal cavity drainage tube device, particularly relates to the technical field of medical instruments, and solves the technical problem that body fluid is easy to seep between a drainage tube and an abdominal wall hole wall to cause pollution during abdominal cavity drainage. The device comprises a collecting bag, a first through hole and a second through hole are sequentially formed in the two sides of the collecting bag in a penetrating mode, a flow guide cylinder is embedded in the first through hole, and one end of the flow guide cylinder extends into the collecting bag; a fixing disc communicated with the guide cylinder is arranged on the outer side of the first through hole, the inner side of the fixing disc is fixed to the surface of the collecting bag, and an adhesive layer is arranged on the outer side of the fixing disc; and a sealing mechanism is embedded in the second through hole. When body fluid exudes between the drainage tube and the hole wall of the abdominal wall, the body fluid enters the collecting bag through the guide cylinder to be collected, and the environment is prevented from being polluted by the body fluid.
