Abstract

The invention discloses a bleeding-stopping pain-relieving dressing and a preparation method thereof. The bleeding-stopping pain-relieving dressing is in the shape of a powder or a composite membrane. The composite-membrane-shaped bleeding-stopping pain-relieving dressing comprises a medicine storage layer and a basic layer which are bonded together via a binder. The provided dressing is applicable to medicinal rapid bleeding stopping, bacteria resisting, inflammation diminishing, wound healing promoting and other aspects.

Description

technical field [0001] The invention relates to a medical dressing, in particular to a hemostatic and analgesic dressing and a preparation method thereof. Background technique [0002] Wound dressings are divided into traditional dressings, biological dressings and synthetic dressings according to their material composition. Among them, biological dressings have the characteristics of good biocompatibility, safety, and quick wound healing, so they are favored by people. The study found that the mechanism of chitosan to promote wound healing is mainly: (1) accelerating PMN cell exudation to the wound area; (2) accelerating exudation to form silk fibrin and activate fibroblasts to move to the wound area; (3 ) Stimulate the movement of macrophages; (4) Stimulate the proliferation of fibroblasts and the production of type III collagen fibers. [0003] At present, the hemostatic dressings put into production and clinical use in the research industry generally have problems such...
