Abstract
The present invention belongs to a sanitary material. The cellulose acetate is used for clinical application instead of natural cotton, can replace absorbent cotton, absorbent gauze and bandages, has the characteristics of no adhesion to wound surface, easy tearing and no pain, promotes wound surface healing, and utilizes the effect of tissue regeneration. The regenerated artificial fiber-acetate fiber is used to replace pure cotton or composite dressing mainly made of pure cotton, so that the resource is saved, and the procedures of degreasing the pure cotton and compounding the dressing are eliminated.
Description
The present invention relates to a kind of new hygienic material, the medical dressing materials without adhesion of particularly making with diacetate fiber.
The dressing that traditional wrapping trauma is used is mostly textile goods.This not only will consume a large amount of high-quality cottons, and for making these dressing absorb wound moisture content and secretions, all needs to do ungrease treatment.The common practice be by cotton to Cotton Gossypii or other dressing processed through alkali liquor high temperature steaming, rinsing, be dried and slough cotton fat and obtain the dressing such as absorbent cotton or absorbent carbasus and binder.In clinical middle these used cotton dressing processed, in the time giving wounded's wound surface dressing, the blood plasma of wound surface or secretions transudate are absorbed by dressing, and can solidly harden at short notice, and dressing and newborn granulation are sticked together, and become stiff plate object.These plate objects are not only oppressed wound surface affects tissue growth, especially in the time of change dressings more, more will destroy the wound of fully recovering and produce for the second time wound, increased new misery to the wounded.
For fear of wound and dressing adhesion, a kind of combine dressing came out already.The dressing that the trade mark of producing as TJSmith and Nephew company of Britain is Airstrip.This is a kind of dressing made from compound certain the semi-permeable plastic sheeting of absorbent cotton.Semipermeable membrane is directly covered to wound, and skin is absorbent cotton, and wound fluid is absorbed by absorbent cotton through semipermeable membrane, and semipermeable membrane plays the effect that prevents dressing and wound surface adhesion.
In sum, no matter be traditional textile dressing or combine dressing, all to consume a large amount of Cotton Gossypiis, and make combine dressing processing technique complexity, cost is higher.
The object of the invention is to overcome the shortcoming that above-mentioned existing dressing exists, make a kind of neither use textile again not with the medical dressing of wound surface adhesion.
Dressing is to be made up through processing of fiber, the object of the invention is by selecting suitable fiber to realize.Fiber is divided into natural fiber and chemical fibre, and chemical fibre is divided into synthetic fibers and artificial regenerated fiber.In general synthetic fibers hydroscopicity is lower, can not meet the needs that absorb secretions and transudate as dressing.Regenerated fiber is to make take the timber of including natural fibers element, phragmites communis, cotton linter, bagasse, cotton stalk, wheat-straw etc. as raw material the staple fibre that pulp obtains through suitable chemical treatment, and its principal item has viscose rayon, acetate fiber and CUP.These fibers are compared with cotton, and hydroscopicity is equally matched, even higher than cotton, can meet moisture absorption requirement as dressing, and through experiment sieving, acetate fiber has the characteristic of not gluing with wound surface.
Acetate fiber of the present invention is by pulp and acetic acid, acetic anhydride, the cellulose diacetate that obtains after esterification under a small amount of sulphuric acid exists, is soft, the fluffy filament of white, tasteless nontoxic, chafe not.Its hydroscopicity or regain, at 20 ℃, are 6-7% under 65% relative humidity, approach (cotton is 7%) with cotton.This fiber can directly replace absorbent cotton also its spinning processing can be become to the gauze of required specification.For example: the plain weave gauze of 21,32,42 or 80 yarn specifications, this gauze can replace absorbent carbasus wrapping wound surface, and acetate fiber is not added to binding agent through mechanical complexation or is copied or alternate manner makes the non-woven fabrics of various suitable specifications.If specification is 50 grams～80 grams/m
2these all can replace absorbent carbasus for Wound dressing as paper mold gauze, also can be made into elastic bandage by certain requirement.If width is 5cm～50cm.
The dressing made from acetate fiber is above called medical dressing materials without adhesion, and quality inspection should meet hygienic material related standards, and using method is identical with textile dressing.Anti-adhesive gauze and paper mold gauze (being non-woven fabrics) through hydrops pool, Beijing hospital burn department to the clinical practice of 102 Li Ci burn woundes, wherein burn surface area the maximum is 95%, clinical observation thinks, this gauze to the depth burn fresh wound surface with easily taking off not bitterly afterwards, granulation wound does not glue, easily take off, not bitterly.BJ Union Hospital's department of dermatologry is to 114 wound surface clinical practices, wherein 95 of suppurative wound surface, and 19 of serosity wound surface, result of the test is:
1,49 wound surface of paper mold anti-adhesive gauze have 46 not glue, easily take off with gauze, and 3 have slight adhesion, wherein still have 3 examples under gauze, to leave some recessive secretions.
2,65 suppurative wound surface of anti-adhesive gauze change dressings with anti-adhesive gauze all do not glue, easily take off, granulation well-grown, without sense of discomfort.
Medical dressing materials without adhesion of the present invention, is applicable to burn, the wound of ulcer, abscess and any wound.Compared with existing textile dressing or combine dressing, replace natural cotton with regenerated fiber, not only can make full use of resource, and textile defat and the compound loaded down with trivial details technique of dressing are avoided, have again simultaneously to wound easily take off, not sticky, painless advantage, favourable wound healing, effect of promotion tissue regeneration.
Anti-adhesive gauze and elastic bandage adopt conventional method, traditional handicraft, spin, weave cotton cloth and make product.
Paper mold anti-adhesive gauze (non-woven fabrics) adopts existing mechanical heat seal or is copied (not adding binding agent) technique and makes finished product.
In order to strengthen the tensile strength of anti-adhesive gauze of the present invention, reduce the end breakage rate occurring during weaving cotton cloth, also can, by acetate fiber material and commercially available Buddhist nun's measuring fiber, be spun into according to a conventional method the fiber of core-skin type composite construction.
Embodiment 1
Take cellulose diacetate as raw material, technique is spinned, is weaved cotton cloth routinely.Can be made into as required the medical non-stick gauze of following specification.
Embodiment 2
Take cellulose diacetate as raw material, technique spinning routinely, weaves cotton cloth, and makes as required the elastic bandage of following specification.
Embodiment 3
Take diacetate fiber as raw material, adopt existing mechanical heat seal or be copied (not adding binding agent) technique and make paper mold anti-adhesive gauze (non-woven fabrics).Its density is 50-80 gram/cm
2.
