Problems solved by technology

Although blending can improve the mechanical and chemical properties of hemostasis, it also limits the type and location of the wound; U.S. Patent US5597581 discloses that hemostasis and alginate are blended by wet spinning, which is worthy of hemostasis, mildew resistance, and bacteriostasis. Performance and healing dressing, the fluid absorption capacity of the blended dressing is 28 times its own weight
But only for chronic wounds with a lot of exudate

Embodiment Construction

[0014] The structure and performance of the hemostatic bandage described in the present invention will be further described below in conjunction with specific inventions and accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention . Invention 1 The hemostatic bandage described in Invention 1 is a layered material composed of a backing layer 10 , a common hemostatic nonwoven fabric 20 , a hemostatic particle layer 30 and a cover 40 . Its functional components include a hemostatic non-woven fabric layer and a hemostatic granular layer, and does not contain other functional components. The common hemostatic non-woven fabric has a thickness of 0.3-0.4 mm and a gram weight of 40-50 g / m 2 , which cannot absorb water and exudate, and its composition is glucosamine polymer. The hemostatic granule layer is composed of rice-yellow deacetylated hemost...

Abstract

The invention relates to a rapid hemostatic bandage. The rapid hemostatic bandage is of a layered structure comprising a functional layer, and the functional layer is composited by a hemostatic healing promoting layer and a 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 rapid hemostatic bandage is suitable for wound fixing, nursing and dressing change of gynecological and obstetric surgery, endoscopic minimally invasive surgery, general surgery, orthopaedic open wounds, cosmetic plastic surgery, outpatient emergency trauma, superficialskin ulcers and the like as well as various punctures, catheters and cathetering, and nursing and dressing change of wounds and wound surfaces such as personal bruises, contusions, knife wounds and small-area burns. The rapid hemostatic bandage 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, more specifically, the invention relates to a hemostatic bandage for promoting wound healing. Background technique: [0002] The skin is an important organ of the human body. It plays a role in controlling body temperature, preventing infection, immunity and sensing. Extensive damage to the skin may result from trauma, abrasions, skin ulcers, and burns. Injured skin can easily lead to bacterial infection, loss of body fluids and complications. In the prior art, wound dressings are usually used to protect the wound, absorb exudate, prevent wound infection, maintain a moist environment of the wound and promote wound healing. The wound dressing has the following requirements: 1) It has a softness similar to that of human skin, and it can maintain a certain shape and strength when it is wet; 2) It can maintain a moist environment on the wound surface and has a good ability to absorb w...
