Wound anti-inflammation and hemostatic composite material strap

Abstract

The invention relates to a wound anti-inflammation and hemostatic composite material strap. The composite material strap is of a layered structure comprising a functional layer, and the functional layer is composited by a chitosan healing promoting layer and a chitosan hemostatic layer. A composite dressing directly makes contact with red blood cells and blood platelets so as to exert the effect without relying on an internal hemostatic mechanism; and irritability is not caused, heat is not released, and the effect can be exerted under the condition of hypothermia. The chitosan composite dressing is suitable for wound fixing, nursing and dressing change of gynecological and obstetric surgery, endoscopic minimally invasive surgery, general surgery, orthopaedic open wounds, cosmetic plasticsurgery, outpatient emergency trauma, superficial skin ulcers and the like as well as various punctures, catheters and cathetering, and nursing and dressing change of wounds and wound surfaces such aspersonal bruises, contusions, knife wounds and small-area burns. The wound anti-inflammation and hemostatic composite material strap has the effects of hemostasis, healing promoting, analgesia, antibiosis and scar generation inhibition.

Description

Technical field: [0001] The invention belongs to the technical field of hemostatic materials, and more specifically, the invention relates to a composite tape for promoting wound healing. Background technique: [0002] The skin is an important organ of the human body, which plays a role in controlling body temperature, preventing infection, immunity and sensing. Extensive damage to the skin can result from trauma, abrasions, skin ulcers, and burns. Bacterial infection, fluid loss, and complications can occur after skin damage. In the prior art, wound dressings are generally used to protect the wound, absorb exudate, prevent wound infection, maintain a moist environment of the wound, and promote wound healing. There are the following requirements for wound dressings: 1) It has soft properties similar to human skin, and can maintain a certain shape and strength when wet; 2) It can maintain the moist environment of the wound and has a better ability to absorb wound secretions...

AI Technical Summary

Problems solved by technology

Although blending can improve the mechanical and chemical properties of chitosan, it also limits the type and location of the wound; U.S. Patent No. 5,597,581 discloses that chitosan and alginate are blended by wet spinning, which is worthy of hemostatic and anti-aging properties. A dressing that has mildew and antibacterial properties and can promote healing. The fluid absorption capacity of the blended dressing is 28 times its own weight

But only for chronic wounds with a lot of exudate
