Abstract

The invention belongs to the technical field of high-molecular medical biomaterials and relates to a calcium alginate composite medical surgical dressing and a preparation method thereof. The calcium alginate composite medical surgical dressing comprises an absorption core layer, a contact surface layer and a composite gel coating. The absorption core layer is a glue layer. The contact surface layer comprises chitosan fibers and active carbon fibers by blending. The composite gel coating comprises, by weight, 2-4 parts of sodium alginate, 0.5-1 part of medical glycerin, 2-4 parts of low molecular weight chitosan, 0.5-1 part of borneol and 80-100 parts of purified water. The medical surgical dressing prepared from the natural material and the synthetic high-molecular material has good absorbency, good biocompatibility, good biological activity and good mechanical properties.

Description

technical field

[0001] The invention belongs to the technical field of polymer medical biomaterials, and in particular relates to a calcium alginate composite medical dressing and a preparation method thereof. Background technique

[0002] As a covering for wounds, medical dressings can replace damaged skin to act as a temporary barrier during wound healing, avoid or control wound infection, and provide an environment conducive to wound healing. With the aging population and the increase of chronic ulcerative wounds, the market value of medical dressings is also becoming more and more important. In 1962, the British Winter proposed the "moist wound healing theory", that is, wounds heal faster in a moist environment than in a dry environment, which made a breakthrough in people's understanding of the wound healing process.

[0003] Medical dressings can be divided into traditional dressings, biological dressings and synthetic dressings according to their materials. Among th...
