Preparation method of anti-adhesion fibrous membrane with hemostatic function

Abstract

The invention relates to a preparation method of an anti-adhesion fibrous membrane with a hemostatic function. Two or three organic polymer solutions are mixed, composite fiber materials in a multi-nozzle electrostatic spinning mode are prepared, and the anti-adhesion fibrous membrane is prepared by treating the composite fiber materials in a crosslinking mode. According to the composite fiber materials prepared by the preparation method, two or three organic polymer solutions are mixed and then processed in a multi-nozzle electrostatic spinning mode by using the electrostatic spinning technology, due to the fact that organic polymer materials is adjusted, the mechanical strength of the organic polymer materials is improved, and meanwhile through crossing treatment, an anti-adhesion material which forms gels on the surface after contacting with blood is prepared, a physical hemostasis effect is achieved, and meanwhile the anti-adhesion fibrous effect is achieved. The preparation method of the anti-adhesion fibrous membrane preparation method with the hemostatic function is simple in technic, easy to operate and low in cost, enables the functions of hemostasis and postoperative adhesion prevention to be achieved, and has wide application prospect in surgical field.

Description

Technical field: [0001] The invention relates to a preparation method of an anti-adhesion fibrous film, in particular to a preparation method of an anti-adhesion fibrous film with a hemostatic function. Background technique: [0002] Most abdominal operations will have different degrees of abdominal adhesions. Studies have reported that the incidence of adhesions after traditional laparotomy is as high as 60-90%, and about 5% of them have adhesive ileus, which not only increases the pain of patients, but also brings great harm to surgical clinicians. Workers put forward a severe challenge, postoperative adhesions have become the main cause of adhesive intestinal obstruction. Therefore, preventing and reducing the occurrence of postoperative adhesions has always been highly valued by clinical surgeons. Most of the products currently on the market only have a simple anti-adhesion function, but scientific research has found that bleeding during surgery is the root cause of adh...
