Abstract
The utility model discloses a kind of composite aquogel wound dressing, comprise mould release membrance, mould release membrance is arranged PU thin film, the another side of described PU thin film arranges pressure-sensitive adhesive layer; One surface attachment of hydrophilic macromolecule hydrogel is on pressure sensitive adhesive; Hydrophilic macromolecule hydrogel another adhere to chitosan film on the surface, chitosan film covers the release paper as protective layer; Release paper is provided with the tearing notch that is conveniently opened use.This utility model is rational in infrastructure, and transparency is high and ductility good, be applicable to the skin trauma that partes corporis humani position operative incision and various wound cause.
Description
Technical field
This utility model relates to a kind of wound dressing, is specifically related to a kind ofly be applicable to the nursing dressing of all kinds of wound of body surface as burn and scald, skin trauma and all kinds of post-surgical incisions.
Background technology
Hydrogel is the one of functional high molecule material, and thus inner have special adsorption to water with strong hydrophilic group, by intermolecular cross-linking, forms network structure.Water absorption gel rubber material water suction feature be different from the adsorbing material such as sponge, cotton, it can absorb the water of sole mass hundreds and thousands of times, and with water strong bonded, then expand formed hydrogel.Also be seldom extruded even if the water in this gel is subject to sizable pressure.This specific function makes absorbent polymer gel rubber material just be developed rapidly after being found.
Hydrogel medical dressing is a kind of novel wound dressing that development in recent years is got up.Compared with traditional dressing, hydrogel can promote that wound heals better, alleviate the pain of patient, not only can not bring secondary damage to wound, can also improve local wound microenvironment, bacteria growing inhibiting.Hydrogel is specially adapted to common body surface wound, as various skin injurys such as scratch, scuffing, decubital ulcers.For these wounds, doctor generally uses sterile gauze and topical antibiotic process traditionally.Gauze easily with skin wound tissue adhesion, usually destroy epithelium and the granulation tissue of new life when changing dressings, cause bleeding, this is not only unfavorable for the healing of wound, and makes Principle of Pain unbearably.Use aerogel dressing when applying ointment or plaster on wound, it not only adhesion wound, do not destroy cambium, and various bacterial reproduction can be restrained, avoid wound infection.
In addition, chitosan has the effect promoting blood coagulation, can be used as hemorrhage; It also has sterilizing, promotes wound healing, absorbs the effects such as Wound exudate, not easily syneresis.
Summary of the invention
The purpose of this utility model is intended to avoid at least one weak point in above-mentioned dressing, thus provide a kind of transparency high and ductility well, be applicable to the composite aquogel wound dressing of the skin trauma that partes corporis humani position operative incision and various wound cause.
Technical solution of the present utility model is:
A kind of composite aquogel wound dressing, is characterized in that: comprise mould release membrance, mould release membrance is arranged PU thin film, the another side of described PU thin film arranges pressure-sensitive adhesive layer; One surface attachment of hydrophilic macromolecule hydrogel is on pressure sensitive adhesive; Hydrophilic macromolecule hydrogel another adhere to chitosan film on the surface, chitosan film covers the release paper as protective layer; Release paper is provided with the tearing notch that is conveniently opened use.
Hydrophilic macromolecule hydrogel and chitosan film measure-alike; The size of PU thin film is greater than the size of hydrophilic macromolecule hydrogel and chitosan film, is fixed by pressure-sensitive adhesive layer and human body.
The size of release paper is greater than the size of hydrophilic macromolecule hydrogel and chitosan film, measure-alike with PU thin film.
Polysaccharide thin layer and hydrophilic macromolecule hydrogel layer form network structure.PU thin film is ultra-thinly be rich in ductility.
This utility model is rational in infrastructure, easy to use, comfortable, there is the interaction of multiple pattern between this utility model dressing and wound, as absorbed transudate and noxious substance, allows gas exchange, for wound healing creates a desirable environment; Barrier layer structure, prevents microorganism invasion in environment, the cross infection of prevention wound.In addition, chitosan has the effect promoting blood coagulation, can be used as hemorrhage; It also has sterilizing, promotes wound healing, absorbs the effects such as Wound exudate, not easily syneresis.
Composite aquogel wound dressing of the present utility model is transparent membranoid substance, be characterized in thin and transparent, soft flexible, be specially adapted to crooked position, when clinical practice, do not need to open the healing state that dressing can observe wound, be conducive to clinical observation and in time more change dressings to guarantee the moist environment of wound healing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
A kind of composite aquogel wound dressing, is made up of 6 layer materials, respectively is release film layer 1, PU elastic film layer 2, pressure-sensitive adhesive layer 3, hydrophilic macromolecule hydrogel layer 4, chitosan film layer 5, off-style paper layer 6.Mould release membrance is arranged PU thin film, the another side of described PU thin film arranges pressure-sensitive adhesive layer; One surface attachment of hydrophilic macromolecule hydrogel is on pressure sensitive adhesive; Hydrophilic macromolecule hydrogel another adhere to chitosan film on the surface, chitosan film covers the release paper as protective layer; Release paper is provided with the tearing notch 7 that is conveniently opened use.
Hydrophilic macromolecule hydrogel and chitosan film measure-alike; The size of PU thin film is greater than the size of hydrophilic macromolecule hydrogel and chitosan film, is fixed by pressure-sensitive adhesive layer and human body.
The size of release paper is greater than the size of hydrophilic macromolecule hydrogel and chitosan film, measure-alike with PU thin film.
Polysaccharide thin layer and hydrophilic macromolecule hydrogel layer form network structure.PU thin film is ultra-thinly be rich in ductility.
