Body cavity negative pressure drainage system based on absorbable porous foaming material

Abstract

The invention discloses a body cavity negative pressure drainage system based on an absorbable porous foaming material. The system comprises a balloon, wherein joints are arranged at two ends of the balloon; a one-way valve structure is arranged in each joint; the joint on one side of the balloon is connected with a drainage main pipe; the tail end of the drainage main pipe is communicated with aplurality of drainage branch pipes; the separable absorbable porous foaming material is inserted into the tail ends of the drainage branch pipes; and the joint on one side of the balloon is connectedwith a drainage bag. The balloon is pressed, the porous structure of the absorbable porous foaming material generates a siphon effect, drainage liquid can be sucked into the porous foaming material tokeep a high-risk area dry, and tissue healing is promoted; the balloon is repeatedly pressed, and due to the action of the two one-way valve structures in the same direction, the drainage liquid is sucked into the drainage bag; and after tissue healing, the drainage main pipe and the drainage branch pipes which are integrated can be pulled out, and the absorbable porous foaming material in the body can be automatically absorbed.

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 absorbable porous foaming 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. This problem is even more serious in the presen...
