Body cavity negative-pressure drainage system based on non-absorbable fiber woven material

Abstract

The invention discloses a body cavity negative-pressure drainage system based on a non-absorbable fiber woven material. The system includes a balloon, two ends of the balloon are joints, and a one-wayvalve structure is arranged in each joint; one joint of one side of the balloon is connected with a drainage main pipe, the tail end of the drainage main pipe communicates with a plurality of drainage branch pipes, and the tail end of each drainage branch pipe is connected with the non-separable non-absorbable fiber woven material; and one joint of the other side of the balloon is connected witha drainage bag. According to the system, the non-absorbable fiber woven material surrounds the parts such as a surgical anastomosis, due to the capillary phenomenon, a liquid around the anastomosis can be sucked into the non-absorbable fiber woven material, the drainage main pipe can draw a drainage liquid in the non-absorbable fiber woven material out of a body through negative pressure, so thatthe dryness of the anastomosis can be guaranteed, the healing of the anastomosis can be promoted, and the risk of infection and bleeding caused by anastomotic leakage can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a body cavity negative pressure drainage system based on non-absorbable fiber braided materials. Background technique [0002] Drainage after surgery in the body cavity is an important part of surgery. After surgery, local tissue exudate, digestive tract fluid, lymph fluid and other fluids need to be drained out of the body. If the postoperative effusion, especially the corrosive digestive juice and pathogen-containing fluid, cannot be properly drained outside the body, local accumulation may cause serious clinical problems such as poor local tissue healing, infection, and local tissue corrosion and bleeding. , these problems can even cause serious surgical complications, lead to secondary surgery or even patient death, and dealing with these problems increases the suffering of patients and takes up a lot of medical resources, and this problem is even more serious in the ...
