Medical use complex chitosan liquor film forming glove
(1) technical field
What the present invention relates to is a kind of gloves, particularly a kind ofly is suitable for medical gloves.
(2) background technology
Gloves are a kind of hand protection articles for use, and according to different needs, people will select different gloves.In medical treatment, particularly used gloves mainly are the emgloves that adopts elastomeric material to make in operation at present.Though along with science and technology development, the performance of emgloves has had bigger improvement, possessed snappiness, elasticity and intensity etc. preferably, it also exists some shortcomings, to such an extent as to can not satisfy the medical specific demand of Denging.These deficiencies mainly show: the one, and feel is relatively poor.The doctor is being with emgloves to undergo surgery, and particularly carries out some for example during the operation of major surgery such as fiber surgery, Neurological Surgery, always has feel sensation not in place, takes the sense of reality of the tool of catching limited, even can influence the operation quality; The 2nd, can cause environmental pollution.The used material of emgloves is nondegradable, and the processing after the use is difficulty quite, and medical gloves is disposable product mostly, and the emgloves after using can not in time be handled, and can cause serious harm to environment.The report that some liquid gloves are also arranged at present, but the composition that wherein contains can not play good sterilization, can not use as medical gloves, generally can only play simple handguard, buffer action, and some one-tenth branches wherein pollute to skin generation pessimal stimulation with to environment.
(3) summary of the invention
Can direct forming when the object of the present invention is to provide a kind of use, with after can natural degradation, to non-stimulated, the free of contamination medical use complex chitosan liquor film forming glove of skin.
The object of the present invention is achieved like this: its liquid is that the ethanol of chitosan 4-8%, polyvinylpyrrolidone 20-30%, glycerol 2-5%, gelatin 4-8% and surplus is formed by weight ratio.
After getting raw material ready in proportion, each raw material mixed to constitute film forming glove liquid, in use, hand is smeared, sprays or be impregnated in to this liquid can form membranaceous gloves.
Main component among the present invention is a chitosan, chitosan can be described as chitosan, chitin, chitosan, chitin, chitin or chitosan again, it is a kind of marine organisms macromolecular material, have film-forming properties preferably, and have nontoxic, good biocompatibility, effective characteristic such as pathogenic microbe killing.The present invention mixes chitosan with compositions such as polyvinylpyrrolidones, the advantage of the medical use complex chitosan liquor film forming glove of forming is mainly reflected in: 1, directly change into membranaceous gloves by liquid, gloves closely contact with hand, user's hand can activity freely, have good hand feeling.2, the effect that has quick sterilization and kill virus can solve the problem of sterilizing and thoroughly not bringing before doctor's hand art well.3, have the physical strength that adapts with range of application, have good wear resistance, flexibility, elasticity and toughness.4, can be after the use with comparalive ease from peeling off on hand, overburden is degradable under field conditions (factors), can not pollute environment.5, shrinkage can not take place after the shaping, can guarantee has good result of use.Have no side effect,, can not produce detrimentally affect, good biocompatibility the user 6, safely.7, have high ventilation performance and moisture-keeping functions.8, rete is thin, and is little to the sensation influence of human hands.The gloves of highly difficult medical procedure such as the present invention can be used as operation, detect also can be used as common medical glovess such as nursing, treatment; The protective gloves that also can be used as work such as the processing of bio-pharmaceuticals aseptic technique, food and makeup and sale, sanitarian cleaning, domestic hygiene cleaning; Can also be used as the protective gloves of other industry, service sector.Be similar between communicable disease burst period such as atypical pneumonia, bird flu, product of the present invention can be applied on one's body the medical personnel that participate in treatment or nursing, preventing that contagium from absorbing infection by oozing skin.
(4) embodiment
For example the present invention is done in more detail below and describes:
1, by weight alcoholic acid ratio each raw material is mixed, constitute film forming glove liquid for chitosan 4-8%, polyvinylpyrrolidone 20-30%, glycerol 2-5%, gelatin 4-8% and surplus.
2, by weight alcoholic acid ratio each raw material is mixed, constitute film forming glove liquid for chitosan 5-6%, polyvinylpyrrolidone 25-30%, glycerol 3-4%, gelatin 5-6% and surplus.
3, by weight alcoholic acid ratio each raw material is mixed, constitute film forming glove liquid for chitosan 5%, polyvinylpyrrolidone 25%, glycerol 4%, gelatin 6% and surplus.
