Abstract
The invention discloses a carboxymethyl chitosan band-aid and a preparation method thereof, belonging to the technical field of medical dressings. The carboxymethyl chitosan band-aid comprises a matrix layer, a wound protection layer which is combined with one side surface of the matrix layer and a peeling layer which covers one side of the matrix layer and shields and protects the wound protection layer, wherein a wavy non-woven medical air-permeable adhesive tape of which one side surface is provided with an adhesive-carrying layer is used as the matrix layer; a carboxymethyl chitosan fiber non-woven fabric is used as the wound protection layer, one side surface of the wound protection layer is combined with an anti-adhesion membrane, and the other side surface of the wound protection layer is combined with the adhesive-carrying layer; and glassine paper is used as the peeling layer. The carboxymethyl chitosan fiber non-woven fabric is used as the wound protection layer, so that ideal effects of stopping bleeding, resisting bacteria, promoting healing and relieving pain can be embodied, and the air permeability and the solution absorption performance of the carboxymethyl chitosan band-aid are excellent.
Description
Technical field
The invention belongs to the medical dressing technical field, be specifically related to a kind of carboxymethyl chitosan adhesive bandage, and relate to the preparation method of this carboxymethyl chitosan adhesive bandage.
Background technology
Adhesive bandage is that the medical application of wound is stopped blooding, protected to a kind of common easy to use and relatively cheap being suitable for that have to little wound surface, it is to using a long narrow adhesive plaster as carrier, in the middle position of the length direction of this adhesive plaster and be positioned at a side and adhere to one piece of tampon of the non-woven fabrics with Antiadhesive film and form.This adhesive bandage is owing to being subject to its structural limitations, thereby the emergence therapeutic that can only tackle small-sized wound, to play the effect of temporary transient hemostasis protection wound surface.Yet, in recent years along with the continuous release of functional living being material, and extend to medical dressing field, thereby enriched medical dressing, make functional adhesive bandage become reality.
The aforementioned functional adhesive bandage mainly contains two classes: a class is medicine-feeding type, add the functional type medicine on the tampon of adhesive bandage, as Yunnan BAIYAO, iodophor solution, Benza, antibiotic medicine etc., antiphlogistic antibacterial by these medicines makes adhesive bandage embody the short function more of antiphlogistic antibacterial, but because be the functional type medicine, so the people knows from experience its generation drug resistance; Another kind of is biological material-type, use functional or title functional fiber material, as chitin fiber, active carbon of silver fiber, alginic acid fibre etc., by non-woven fabrics craft, these functional fibers are made to tampon, then finally make adhesive bandage, this class adhesive bandage utilizes the characteristic of fibrous material self to play the antibacterial heal-promoting function, and human body does not produce drug resistance.Therefore this type of functional adhesive bandage has good market prospect.
In functional fiber material, the application of chitin fiber is comparatively extensive, the medical dressing field chitin is applied ointment or plaster at home, the chitin adhesive bandage continues to bring out like the mushrooms after rain, but most of product has only utilized this concept of chitin brand-new material, the non-constant of its absorbent, so-called hemostasis, antibiotic, short more and pain relieving often can not find rational explanation foundation from medical pathology angle.
After by highly basic and high-temperature process; the part N-acetyl group of chitin comes off; so chitin becomes the chitosan of different deacetylations; deacetylation is higher simultaneously, and chitosan occurs that the effect of blood coagulation and solidifying protein is better, so chitosan can play hemostasis, antibacterial action from the pathology angle; but because chitosan is processed through highly basic; so highly basic can produce certain injury to wound, simultaneously because chitosan (chitosan) and water are immiscible, thereby absorbent is unsatisfactory.Chitin and monoxone have water solublity through mediating technique (etherificate) formation carboxylate, so far obtain carboxymethyl chitosan.
Because carboxymethyl chitosan has good water solublity and has the effects such as film forming, thickening, moisturizing, gel, thereby these characteristics can play good effect to the healing of wound, really reach hemostasis, antibiotic, short more, the effect of pain relieving.So the carboxymethyl chitosan fiber is the elite clone of producing adhesive bandage.
Disclose the technical information of utilizing the adhesive bandage that carboxymethyl chitosan makes in disclosed Chinese patent literature; as Granted publication CN202458908U recommends to have " adhesive bandages "; its by matrix, be combined in a side surface of matrix medical adhesive, be combined in the medicine film that the local location (middle position) of medical adhesive locates and cover medicine film surface and prolong and, to the stickup protective layer (release paper) of all sites of medical adhesive, the medicine film of this patent is to be mixed by carboxymethyl chitosan and YUNNAN BAIYAO.Hence one can see that, and the medicine film of this patent is not to be served as by the carboxymethyl chitosan fiber non-woven.
The patent application publication No. CN101927027A provide " chitosan/carboxymethyl chitosan rapid hemostatic sponge and preparation method thereof ", and it is by forming for the carboxymethyl chitosan of the chitosan of 48-62%, 13-14% and the glycerol of 24-39% by mass percentage.This patent scheme is not to be served as by the carboxymethyl chitosan fiber non-woven equally, especially by known to the explanation on description the 0004th and 0005 hurdle, because needs are cast in mould mixed liquor through lyophilization (15-35h), thereby not only preparation time is long, complex technical process, and preparation efficiency is low.
In view of above-mentioned prior art, the applicant has carried out for a long time and good try, and technical scheme described below produces under this background.
