| titleOfInvention | A kind of negative pressure sealing drainage dressing and preparation method thereof |
| abstract | The invention discloses a negative pressure sealing drainage dressing and a preparation method thereof, comprising a polyurethane foam material layer, the surface of the polyurethane foam material layer is covered with a degradable polymer layer, and the side of the polyurethane foam material layer close to the wound is compounded With anticoagulant layer. In order to solve the two problems of polyurethane foam sticking new granulation tissue and blockage, the invention can effectively prevent blood clots on the wound surface by coating the polyurethane foam with an anticoagulant layer on the contact side of the wound, thereby effectively solving foam blockage and drainage. In addition, under the action of negative pressure for a long time, it will stimulate the production of granulation tissue on the wound surface and may grow into the foam. At this time, the degradable polymer on the surface of the foam will gradually degrade, and the new granulation tissue will integrate Gaps are formed between the pores, and when the foam is removed, the granulation tissue is not disrupted. |
