Description
Technical field
The present invention relates to field of medical materials, particularly relate to a kind of medical bandage and the preparation method with sterilizing and itch-relieving function.
Background technology
Binder, as the typical products of medical textile, can prevent wound from injuring again, properly regulate the temperature and humidity of wound, reduces complication and prevents the infection phenomenon in normal healing process, and make wounded body feel comfortable.The research of wound physiologist shows, wound keeps certain humidity to be conducive to the diffusion of Skin Cell, the healing of accelerated in wounds.In wound healing process, wet environment can prevent contraction from overrunning and scabbing, and a large amount of body fluid that wound oozes out at first easily make bacterial reproduction and cause infecting, and therefore effectively absorb these body fluid, keep a gnotobasis to be very necessary in wound.So the following effect of tool answered by desirable binder: (1) keeps wet environment with the healing of accelerated in wounds in wound.(2) liquid and noxious substance that wound oozes out can be removed.(3) certain elasticity must be had.(4) keep wound not infected.(5) nontoxic, inviscid, binder does not produce new wound when dismantling.(6) stand various disinfecting and never degenerate.
Application publication number CN102366640A(application number 201110311652.3) Chinese patent literature disclose a kind of Zeolite tourniquet bandage, it comprises hospital gauze, hospital gauze is adsorbed with hemostatic compositions, described hemostatic compositions comprise by weight percentage in the zeolite powder of 50%-95%, the sodium chloride of 3%-30%, potassium nitrate, ammonium salt, carbamide, sodium bicarbonate one or more, the binding agent of 2%-20%.Application publication number CN104264485A(application number 201410477406.9) Chinese patent literature disclose a kind of preparation method being coated with the medical bandage of polyurethane resin performed polymer, comprise the following steps: a, add aromatic diisocyanate, dehydrant in a kettle., polyether Glycols, polyether-tribasic alcohol, high molecular weight polyethylene glycol, defoamer, white carbon, lubricant, catalyst is added again after stirring, be warming up to 75 DEG C of insulations, then be down to room temperature, then obtain base polyurethane prepolymer for use as; B, pulverous nanometer particle, zinc oxide, far-infrared emission material are added in dehydrated alcohol and coupling agent solution, dryly after fully stirring also grind, then obtain functive powder; C, join in base polyurethane prepolymer for use as by functive powder, under nitrogen protection condition, abundant stirring reaction, then obtain polyurethane resin performed polymer; D, polyurethane resin performed polymer is evenly coated in Ji Bushang, through work feed, roll-in, rolling, shearing, sealing, packed, obtains the medical bandage being coated with polyurethane resin performed polymer.Application publication number CN103405802A(application number 201210240496.0) Chinese patent literature disclose a kind of preparation method with the medical polyurethane binder of sterilizing and itch-relieving, comprise the steps: chitosan microball or the chitosan quaternary ammonium salt first preparing base polyurethane prepolymer for use as He there is sterilizing and itch-relieving function, again base polyurethane prepolymer for use as is evenly coated in Ji Bushang, the Ji Bu being coated with base polyurethane prepolymer for use as carries out coating chitosan microball or chitosan quaternary ammonium salt again under the guiding of guide.
At present, it is undesirable to there is breathability in the binder generally used, and patient skin can have the phenomenon of pruritus redness to occur because binder breathability is good not in use, also deposits the problems such as comfort level is in use lower in addition.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of medical bandage and the preparation method with sterilizing and itch-relieving function.Products obtained therefrom of the present invention has no side effect, good permeability, hygroscopicity is strong, and to human body without pessimal stimulation, there is pesticide-germicide, antipruritic, mind calming is only throbbed with fear, antiinflammatory, the effect such as eliminating stagnation eliminating mass, there is good bio-compatibility, effectively can kill the antibacterial of skin surface, prevent red swelling of the skin pruritus, prevent wound infection, for patient provides dry comfortable rehabilitation environment, patient uses comfortable, easy to use.
