A kind of hemostatic compound dressing for medical trauma

Abstract

The invention discloses a hemostatic composite dressing for medical trauma. The invention uses dandelion fluff / viscose fiber non-woven fabric as a base material, and uses a vacuuming method to fill gluten protein, oxidized sodium alginate, and chitosan composite polymer materials. A medical wound hemostatic composite dressing with high water absorption, good air permeability and antibacterial properties is obtained between the fibers and the surface of the non-woven fabric. The dressing not only has good mechanical strength, but also has anti-adhesion, fast hemostasis and wound healing effects , shorten the wound healing time.

Description

technical field [0001] The invention belongs to the field of medical supplies, in particular to a medical trauma hemostasis composite dressing. Background technique [0002] The skin provides protection for the human body. Once the skin is injured, it will have a great impact on bodily functions. Therefore, after the skin is injured, the wound needs to be protected in time to avoid infection. Medical materials, whose main function is to control the exudate of the wound, accelerate wound hemostasis, protect the wound surface to prevent bacteria and fine dust from contaminating the wound, and promote wound healing; currently commonly used wound repair products include natural fiber dressings (gauze), synthetic fiber dressings , gel dressings and sponge dressings; natural cellulose such as gauze mainly acts as a physical barrier to the wound, does not have antibacterial and wound healing effects, and has poor affinity with the wound; synthetic fiber dressings It is usually pre...

Problems solved by technology

[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 protect the wound in time to avoid infection of the wound; medical dressings are used as a temporary treatment for wounds. Medical materials, its main function is to control wound exudate, accelerate wound hemostasis, protect the wound surface from bacterial and dust contamination of the wound, and promote wound healing; currently commonly used wound repair supplies include natural fiber dressings (gauze), synthetic fiber dressings , gel dressing and sponge dressing; natural cellulose such as gauze mainly acts as a physical barrier to the wound, does not have antibacterial and wound healing effects, and has poor affinity with the wound; synthetic fiber dressing Usually prepared from biopolymer materials, it has good affinity with the wound, but its permeability is high, and it is easy to cause the dressing to adhere to the wound when it is peeled off from the wound, and it is not easy to remove from the wound surface; gel dressing , is to form a gel through the dressing to absorb the wound exudate; this kind of dressing will have a colloid layer with a network structure formed after the surface dressing first contacts the wound to absorb liquid, which hinders the inner dressing from further absorbing liquid. This prevents the "fish-eye" phenomenon of the gel dressing; limits the effective utilization of the dressing;
