CN2549949Y - Chitin wound plaster - Google Patents

Abstract

The utility model discloses a chitin wound plaster which consists of a bottom layer, a material pavement layer fixed on the bottom layer, and an adhesive prevention layer covering the whole bottom layer and the material pavement layer, wherein, the bottom layer is a medical press adhesive; the material pavement layer takes a double layer structure, with the lower layer being non-woven cloth absorption mat and the upper layer being; the adhesive prevention layer is an adhesive prevention paper coated with silicon oil. The utility model is simple in structure and can achieve the industrial scale production, with the use convenient. The paved material adopted by the utility model is chitin which is a pure natural biopolymer extracted from the sea shell creatures and the shells of the pods and is a substance similar to the ossein albumen structure of the human body and has the advantages of good biological compatibility, small immunity antigen, no agglutination to the trauma, water absorption, good agglutination, etc. during the use. The utility model has the functions of diminish in inflammation, blood stopping, pain ease, muscle growing, cell and organization grow promotion, traumatic surface recovery speeding, scar reduction, etc.

Description

The chitin wound pastes

Technical field

This utility model relates to a kind of medical, can stop blooding, can quicken the dressing of wounded tissue wound healing again, specifically the chitin wound pastes (claiming the subsides of chitin wound, the subsides of chitin wound, the subsides of chitosan wound, chitin trauma plaster, chitin adhesive bandage again).

Background technology

Traditional wound pastes or adhesive bandage, and the dressing layer that they adopt mostly is the degreasing fabric of sterilization greatly, and its main effect is hemostasis and protection wound surface.CN1121836A discloses a kind of Wound surface protection film, and it is to be processed into fibroin protein film after treatment by silkworm silk, and this film and tissue intermiscibility are good, and is ventilative, permeable, plays the not infected effect of protection wound surface.Chinese patent 96122932 disclosed a kind of soluble wound bandages with fast-acting nemostatic and promoting muscle growth functions, it is made of bottom and the protective layer that is fixed on the dressing layer on the bottom and covers whole bottom and dressing.Wherein dressing layer is a kind of soluble fiber.

Summary of the invention

The purpose of this utility model provide a kind of not only had antiinflammatory, hemostasis, but also can analgesia, granulation promoting, the growth of promotion cell tissue, quicken the wounded tissue wound healing, the chitin wound that reduces stasis of blood trace pastes, and pastes the weak point that exists to solve existing wound.

In order to realize the foregoing invention purpose, the technical scheme that this utility model adopted is: the chitin wound pastes, constitute by bottom and the adherent layer that is fixed on the dressing layer on the bottom and covers whole bottom and dressing layer, bottom can be a medical pressure-sensitive adhesive, and its effect is to adhere to dressing and make it to be fixed on people's the skin.Dressing layer is a double-layer structure, and its lower floor is the non-woven fabrics absorption pad, and the upper strata is the chitin biological dressing.Adherent layer is the separate paper that scribbles silicone oil, covers in bottom and the dressing, prevents pressure-sensitive adhesive plaster adhesion packing material.

Open adherent layer during use, dressing is covered on wound surface or the wound, get final product with bottom is fixing.This utility model is simple in structure, can realize industrial scale production, and is easy to use.What dressing of the present utility model adopted is a kind of pure-natural biological high polymer---the chitin that extract from the carapace of marine organisms or Bombyx bombycis, makes with extra care through scientific method to form again.And the chitin ecomone is unique band cationic substance that present occurring in nature is found, its chemical name is (1,4-2-acetamide-2-deoxidation-β-D-glucose), from molecular structure, they have the structure similar to plant cellulose, on their macromolecular each repetitives, an acetamido or amino are arranged all, structure with similar human body ossein tissue, has fabulous biocompatibility with human body, after being absorbed by the body, the polysaccharide body of decomposition is that the base substance and the human tissue cell that constitute human body have good affinity, can promote the human cell tissue hypertrophy, quicken the healing of injured wound surface.

The chitin ecomone can make pH value meta-alkalescence in the body, and intravital immunocyte is active maximum when pH value 7.4 left and right sides, and it can tell normal cell and harmful cell, and kills harmful cell.The basic character of chitin ecomone has been created the environment of a suitable immunocyte kill pathogens, reinforced immunological function, the attacking ability of activated lymphocyte.

Become chitosan behind the chitin macromole deacetylate, but complete hydrolysis becomes glucosamine, has analgesic activity.

The glucosamine structural similarity that exists in chitin and the body is safe so use human body, under the effect of lysozyme biodegradation can take place in vivo, has good biological activity, absorbed by human body safety, have antiinflammatory, hemostasis, analgesia, antibacterial, granulation promoting, promote effects such as wound healing.This utility model is applicable to minor operation otch, knife injury, incised wound, scratch, decubital ulcer, furuncle and phyma, shallow epidermis skin ulcer, small size minor burn, scald etc.

The specific embodiment

The present invention will be further described below in conjunction with accompanying drawing

As shown in Figure 1, get medical pressure-sensitive adhesive and make bottom 1, be cut into serial rectangle, as 7.5 * 2.5 centimetres etc.Get non-woven fabrics absorption pad 2 and do the lower floor of dressing layer 3, chitin biological dressing 4 is done the upper strata of dressing layer 3.Dressing layer 3 is fixed on the bottom 1, also is corresponding rectangle.Cover one deck on it and scribble the separate paper of silicone oil as adherent layer 5.Here it is, and the chitin wound pastes.

Present embodiment is divided into round or two kinds of rectangles, and its specification is as follows:
