Problems solved by technology

[0004] The purpose of the present invention is to provide an easy-to-extract anti-residual tissue effusion drainage system, which solves the problem that in the prior art, it is easy to tear the healed tissue during the extraction process after the drainage, which causes the wound to re-expand, and in the drainage cavity Leaving some residual substances that cannot be absorbed by human tissues, resulting in slow postoperative recovery and affecting the treatment effect

Embodiment 1

[0034] like figure 1 , figure 2 , image 3 and Figure 8 An easy-to-pull-out anti-residual tissue effusion drainage system shown includes a drainage tube 1, a drainage head 2 and a foamed sponge 3 wrapped and arranged outside the drainage head 2, and the foamed sponge 3 is expanded by a porous foamed polymer material. The material and parameters of the foamed sponge 3 are determined according to histocompatibility and physical properties. Taking the PVA foam sponge as an example, the apparent density can be adjusted to about 0.06g / cm3, the pore size can be adjusted to <1200μm, the surface of the foam sponge 3 is covered with a shaping net 4, and the end of the shaping net 4 is fixed on the Insert a section of drainage tube 2 in the foam sponge 3, insert the drainage head 2 into the foam sponge 3, and fix the drainage tube 1 and the foam sponge 3. The fixing method can be selected but not limited to adhesive bonding, Sutures, etc., the foam sponge 3 is connected with the d...

Abstract

The invention relates to a drainage system easy to pull out and capable of preventing residual tissue effusion, the drainage system comprises a drainage tube, a drainage head and foaming sponge wrapping the drainage head, the foaming sponge is prepared by expanding and foaming a high polymer material, and the surface of the foaming sponge is covered with a shaping net. The end of the shaping net is fixed to the section, not inserted into the foaming sponge, of the drainage tube, a macromolecule sliding film is arranged at the position, connected with the drainage tube, of the foaming sponge, the macromolecule sliding film is in an arc shape and wraps the outer side of the shaping net, the drainage tube is connected with a negative pressure balloon and a drainage bag, and the negative pressure balloon is connected with the foaming sponge. And one-way valves are arranged in the drainage tube at the two ends of the negative pressure balloon. The drainage head can be conveniently taken out after drainage is finished, meanwhile, damage to drainage cavity tissue is avoided, the resistance for pulling out the drainage tube is reduced, it is avoided that residual matter which cannot be absorbed by human tissue is left in the drainage cavity, and the postoperative recovery speed is increased.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to an easy-to-pull-out anti-residual tissue effusion drainage system. Background technique: [0002] Drainage after body cavity surgery is an important part of surgery. After surgery, local tissue exudate, digestive tract fluid, lymph fluid and other fluids need to be drained to the outside of the body. Postoperative fluid accumulation, especially corrosive digestive fluid and fluid containing pathogens, if it cannot be accurately drained to the body, local accumulation may cause serious clinical problems such as poor local tissue healing, infection, local tissue corrosion and bleeding, etc. , these problems can even cause serious surgical complications, lead to secondary operations and even death of patients. Dealing with these problems increases the suffering of patients and takes up a lot of medical resources. However, the problem is more serious in the presence of bili...
