Abstract
The invention provides a medical negative-pressure adsorption dressing and application of the medical negative-pressure adsorption dressing in wound surface healing. The medical negative-pressure adsorption dressing is made of a sheet absorbent material, the sheet absorbent material comprises an absorbent layer of a three-dimensional interworking network structure and a wound surface contact face of a three-dimensional interworking network structure, wherein the wound surface contact face is loaded on at least one side of the absorbent layer, and a plurality of negative-pressure drainage holes penetrating through the thickness portion of the sheet absorbent material and a wound observing hole are formed in the sheet absorbent material. Due to the fact that the medical negative-pressure adsorption dressing is provided with the absorbent layer of the three-dimensional interworking network structure and the negative-pressure drainage holes, thick oozed pus or blood on the wound surface is wholly and rapidly absorbed into the dressing, a wet environment of the wound surface can be kept, cellulose or protein and other solid compositions in the ooze between the wound surface and the dressing are prevented from being left, bacteria and other microorganisms are prevented from breeding on the wound surface, the opportunities of wound surface infection are greatly decreased, the wound surface can directly heal without scabbing, and the wound surface healing time is greatly shortened.
Description
Technical field
The present invention relates to and a kind ofly to wound surface thickness transudate, there is good absorption, wound surface moist environment, wound surface can be kept for a long time can to skip the negative-pressure adsorption medical dressing of incrustation phase adhesion.
Background technology
Traditional wound healing generally uses gauze, powder formulation, spray, ointment, cream, sponginum etc., and major part, through absorbing the transudate of wound face, makes wound location dry, then heals.In recent years, find that the healing of wound dryness exists following problem: 1) wound surface local dehydration, forms incrustation, hinder epithelial creeping; 2) wound bioactive substance is lost, and healing rate is slow; 3) frequent more change dressings, makes wound surface local temperature decline, causes cell division growth rate to slow down; 4) the without hindrance impenetrability barrier of wound surface and the external world, the chance of infection increases; 5) wound healing time is long; 6) dressing and the adhesion of wound new granulation tissue, causes property damage occurs again during each more change dressings, makes patient pain.
1962, Britain doctor Winter confirms in zoopery, under wet environment, speed of wound healing is 2 times under dryness environment, simultaneously, wound local is moistening, can not incrustation be formed, and maintain the hypoxia of wound surface local microcirculation, be beneficial to the dissolving of slough and the proliferation and differentiation of cell, retain the active substance in transudate and promote that active substance discharges, creating the healing environment close to physiological status.The advantage of wound wet union may be summarized to be: 1) closure dressing, and infection chance declines; 2) local temperature is close to body temperature, and cell division growth rate is fast; 3) wound healing time is shortened; 4) dressing not with the adhesion of wound new granulation tissue.
The material of the advanced dressing of above-mentioned wound wet environment is provided to have: film dressing, foam dressing, hydrogel, bearing hydrocolloid dressing, the dressing of alginic acid salt, exist between these advanced dressing and wounds and interact, as absorbed transudate, allow gas exchange, for ecotopia is created in healing; Prevent external environment microorganism from invading, prevent wound infection; Self has activity, and can promote has active substance to play a role, with accelerating wound healing.
In above-mentioned advanced dressing, Japanese Patent Laid-Open No. Sho 58-87153 publication discloses the dressing of a kind of polyurethane film wound, and it has good retractility, but do not absorb the performance of transudate completely, therefore, during for oozing out the wound surface of transudate, hydrops is caused, need the step of carrying out draining, in addition, adhesion strength is too strong, when causing changing, with pain, regeneration skin can be lost.
Bearing hydrocolloid dressing contains hydrophilic colloid particle, has the absorbability of transudate, but wound face easily residual spawn when changing, and not easily observes wound face, when changing, also can produce adhesion and with pain.
PVA aerogel dressing be containing have an appointment 80% water, therefore, owing to maintaining moist environment, good cooling results, and the transparency good, be easy to wound observation, but almost there is no adhesion strength, must the auxiliary immobilization materials such as binder be had.
Japanese Patent Laid-Open 8-187280 publication discloses the dressing of a kind of alginic acid salt, such dressing has the absorbability of good hemostatic and transudate, but because transudate there will be gelation, so easily remain spawn when changing on wound surface, and be open, therefore for remaining moistening, preventing antibacterial from invading, preventing bacterial multiplication, must cover with thin-film material.
Summary of the invention
The present invention solves the aforementioned problems in the prior proposition.
The invention provides a kind of negative-pressure adsorption medical dressing and the application in wound healing thereof, because described negative-pressure adsorption medical dressing has liquid-adsorption layer and the negative pressure drainage hole of three-dimensional interworking network structure, the sepage of wound surface thickness or oozing of blood entirety promptly suck in dressing, wound surface moist environment can be kept, and to avoid between wound surface and adjuvant the residual of the solid constituent such as cellulose or protein in transudate, eliminate the cultivation of the microorganisms such as antibacterial on wound surface, greatly reduce the chance of traumatic infection, wound surface can skip the adhesion of incrustation phase, substantially reduce wound healing time.
For achieving the above object, the present invention is by the following technical solutions:
