Alginate dressing

Abstract

The invention discloses alginate dressing. The alginate dressing is composed of three layers of structures including a collagen / alginate layer, a manganese dioxide layer and a liquid silicone rubber layer, and the layers are bound through physical and chemical action to form an alginate dressing layer similar to a single-layer structure. A preparation technology is simple, and use is convenient. The collagen / alginate layer is obtained in the mode that a fish scale collagen protein enzymatic hydrolysate is adsorbed by an alginate film base body prepared from a biopolymer material through the 3Dprinting technology; the manganese dioxide layer is obtained by coating of a cyclodextrin solution wrapping manganese dioxide; and the liquid silicone rubber layer is obtained by mixed sulphurizationof silver-loaded polyethyleneimine and liquid silicone rubber. The layers cooperate to enable the dressing to have excellent water-absorbing antibacterial performance, the dressing can also provide oxygen and nutrient substances for wounds, a proper microenvironment is provided for wound healing, wound healing is promoted, the healing period is shortened, and pain of patients is reduced.

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;
