an alginate dressing

Abstract

The invention discloses an alginate dressing. The alginate dressing is composed of a three-layer structure, including a collagen / alginate layer, a manganese dioxide layer, and a liquid silicone rubber layer. The layers interact with each other through physical and chemical interactions. It is bonded into an alginate dressing layer similar to a single-layer structure; the preparation process is simple and the use is convenient. Among them, the collagen / alginate layer is obtained by absorbing fish scale collagen enzymatic hydrolysis solution on the alginate membrane matrix obtained by biopolymer material using 3D printing technology; the manganese dioxide layer is obtained by encapsulating manganese dioxide in a cyclodextrin solution The liquid silicone rubber layer is obtained by mixing and vulcanizing silver-loaded polyethyleneimine and liquid silicone rubber; the synergistic effect between the layers makes the dressing not only have excellent water absorption and antibacterial properties, but also provide oxygen and Nutrients provide a suitable microenvironment for wound healing, promote wound healing, shorten the healing cycle, and relieve pain for patients.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an alginate dressing. Background technique [0002] The skin provides protection for the human body. Once the skin is injured, it will have a great impact on body functions; therefore, after the skin is injured, it is necessary to use dressings to protect the wound to prevent the wound from being infected; oxygen plays an important role in the healing process of the wound. Function: On the one hand, it inhibits the growth of anaerobic bacteria; on the other hand, it promotes the regeneration of cells; and the wound will have a problem that is not conducive to wound healing due to lack of oxygen, which can be improved by external oxygen supply. The purpose of protecting the wound hinders the gas exchange between the wound and the outside world, and cannot achieve the effect of supplementing oxygen for the wound, so that the wound heals slowly. [0003] As a biopolymer material, al...

Problems solved by technology

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of alginate dressing, which has excellent hemostasis and antibacterial effect, does not adhere to the wound, can provide oxygen and nutrients for the wound at the same time, and provides suitable for wound healing. The microenvironment promotes wound healing and solves the problem that current wound dressings only have protective and antibacterial effects but cannot provide sufficient oxygen for wound healing and promote wound healing;
