Description
Technical field
This utility model relates to a kind of Medical wounded surface dressing with infection function.
Background technology
Because the external world causes injury the factor as surgical operation, external force, heat, electric current, chemical substance, low temperature and body intrinsic factor are as caused dissimilar skin wound under the effects such as local blood supply obstacle, cause the destruction of skin complete and the loss of a certain amount of normal structure, rebuilding or recovering skin function is the final goal of clinical treatment wound surface, reaching before this target, scientific research personnel develops dissimilar wound-surface cover, be dressing, make it temporarily play the partial action of skin barrier function, an environment that is conducive to wound healing is provided, wait for ］ wound surface epithelization or be transitioned into rebuild permanent skin barrier.Along with the physiopathologic further investigation to wound, people are also more and more deep to the understanding of wound, thereby promoted updating and developing of Wound dressing.Today, novel Wound dressing, with respect to revolutionary variation has occurred in early days, from passive-type dressing, develops into coactive pattern dressing, then develops biological active dressing now.
Desirable Wound dressing should meet following requirement: prevent the loss of moisture content and body fluid; Resist bacterial invasion, protect from infection; There is affinity with wound surface, have good bonding force; Keep, promote granulation and epithelial tissue normal growth, promote recovery from illness; Preventing from scar, do not produce distortion; Softness, has certain mechanical strength; Ventilative, moisture-inhibiting, has moisture retention; Good biocompatibility; Comfortable, convenient, preparation easily, cheap.The optimal method of flap coverage is self-skin transplant, but transplants often deficiency of skin source.Along with the development of Polymeric Industry, dressing prepared by synthetic material is also increasing, roughly has thin film class, liquid type, spray-like, foam class, Hydrogels etc.The dressing of thin film class, is mainly polyurethane film and the large class of organosilicon membrane two, has the advantage of air-and water-permeable, and can be suppressed to fibrocellular propagation, clinically scar after the operation is had to good effect.The main deficiency of this dressing is not strong to the absorbability of sepage, easily causes the accumulation of transudate, infects, therefore film type dressing is to be mainly used in cleaner wound thereby cause.Liquid dressing refers to dressing is sprayed on to wound, and formation layer protective layer, maximum feature is to be applicable to various wound surface shapes, but how the usually toxic effect of effects on surface blood vessel of high polymer that this dressing uses now need not.Spray-like dressing be by macromolecule polymer solution direct spraying in wound surface, the feature of this dressing is soft and transparent, easy to use, but its intensity is poor, when use, easily for transudate softens, the retention time is shorter, performance of keeping humidity is bad.The dressing of foam class has loose structure, loose structure is given its very strong absorbability and good gas-premeable, most typical is polyurethane and polyvinyl alcohol foam dressing, the main deficiency of such dressing is the growth that loose structure can be induced granulation tissue, thereby cause the adhesion to wound, cause the difficulty removing.The dressing of aquogel type refers in polymer precipitation and has used hydrogel material, the existence of polymer liner, stop the surperficial dehydration of wound and be dried, can effectively alleviate patient's deeply worried pain perception, but the mechanical strength of aquogel type dressing being to be improved.To sum up, between the nearly more than ten years, the research of dressing has had breakthrough progress, but still has some defects, also has a segment distance from the requirement of desirable dressing.
In fact, the natural fibrous material such as cotton, lint, gauze is still clinical the most widely used dressing materials at present.But gauze belongs to inertia dressing, to the healing of wound surface without obvious facilitation, when dressing is soaked into, the easy infected wound of pathogen; And the maintenance cost of this dressing is large, the workload of changing dressings is large, and cannot effectively stop the intrusion of antibacterial, antibiotic medicine gauze adds ingredient in the time that gauze uses, also be the common maneuver of processing wound, but cannot solve common antibiotic resistance problem, can not reach desirable infection effect.
