Abstract
The utility model relates to a carboxymethyl chitosan band aid and belongs to the technical field of medical dressings. The carboxymethyl chitosan band aid comprises a substrate layer, a wound protecting layer combined on one side surface of the substrate layer and a stripping layer which is covered at one side of the substrate layer and also shields the wound protecting layer, the substrate layer is a corrugated non-woven medical ventilate rubberized fabric with a glue carrying layer on one side surface, the wound protecting layer is a carboxymethyl chitosan fiber non-woven fabric, an anti-adhesion film is combined on one side surface of the wound protecting layer, the other side surface of the wound protecting layer is combined with the glue carrying layer, and the stripping layer is glassine. The wound protecting layer adopts the carboxymethyl chitosan fiber non-woven fabric, so that ideal hemostasis, antibacterial, healing promoting and pain stopping effects can be reflected, and air permeability and solution absorption performances are excellent.
Description
Technical field
This utility model belongs to the medical dressing technical field, is specifically related to a kind of 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 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 non-woven fabrics tampon that has Antiadhesive film and constitute with a long narrow adhesive plaster.This adhesive bandage is owing to be subjected to its structural limitations, thereby the emergence therapeutic that can only tackle small-sized wound, to play the effect of temporary transient hemostasis and protection wound surface.Yet, in recent years along with the continuous release of functional living being material, and extend, thereby enriched medical dressing to medical dressing field, make functional adhesive bandage become reality.
The aforementioned functional adhesive bandage mainly contains two classes: a class is to add Types of Medicine, on the tampon of adhesive bandage, add the functional type medicine, 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, function of use or title functional type fibrous material, as chitin fiber, active carbon of silver fiber, alginic acid fibre etc., by non-woven fabrics craft these functional fibers are made tampon, finally make adhesive bandage then, this class adhesive bandage utilizes the fibrous material self characteristics 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 the functional type fibrous 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 notion of chitin brand-new material, the non-constant of its absorbent, so-called hemostasis, antibiotic, short more and pain relieving often can not find the proper explanations 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 high more simultaneously, and the effect that blood coagulation and solidifying protein appear in chitosan is good more, so chitosan can play hemostasis, antibacterial action from the pathology angle; but because of chitosan is handled through highly basic; so highly basic can produce certain injury to wound, simultaneously because chitosan (chitosan) is immiscible with water, thereby absorbent is unsatisfactory.Chitin and monoxone have water solublity through mediating technology (etherificate) formation carboxylate, so far obtain carboxymethyl chitosan.
Since carboxymethyl chitosan have good water solublity and have film forming, thickening, preserve moisture, effect such as gel, thereby these characteristics can play good effect to the healing of wound, really reach hemostasis, antibiotic, shortly heal, the analgesic effect.So the carboxymethyl chitosan fiber is an elite clone of producing adhesive bandage.
In disclosed Chinese patent literature, disclose the technical information of utilizing the adhesive bandage that carboxymethyl chitosan makes; recommend to have " novel adhesive bandage " as Granted publication CN202458908U; its by matrix, be combined in a side surface of matrix medical glue, be combined in the medicine film that the local location (middle position) of medical glue locates and cover medicine film surface and prolong and to the stickup protective layer (release paper) of all sites of medical glue, 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.
Patent application publication No. CN101927027A provides " chitosan/carboxymethyl chitosan rapid hemostatic sponge and preparation method thereof ", and it is by constituting 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 as can be known to the explanation on description the 0004th and 0005 hurdle, owing to mixed liquor need be cast in the mould 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 long-term and good try, and technical scheme described below produces under this background.
Summary of the invention
Task of the present utility model is to provide a kind of carboxymethyl chitosan adhesive bandage that helps to embody ideal hemostasis, antibiotic, short and analgesic effect and help embodying high ventilation, absorbent.
Task of the present utility model is finished like this, a kind of carboxymethyl chitosan adhesive bandage, comprise base layer, be incorporated into the protecting wound layer and cover a side of base layer and cover the peel ply that protects to protecting the wound layer simultaneously an of side surface of base layer, described base layer is that a side surface has the ripple type on-woven medical air-permeable adhesive plaster that carries glue-line, the described wound layer that protects is the carboxymethyl chitosan fabric nonwoven cloth, be combined with Antiadhesive film at this side surface that protects the wound layer, and the opposite side surface of protecting the wound layer combines with described year glue-line, and described peel ply is Ge Laxin.
In a specific embodiment of the present utility model, the thickness of described year glue-line is 0.1-0.5 ㎜; Described grammes per square metre of protecting the wound layer is 70-120g/ ㎡; The grammes per square metre of described peel ply is 60-100g/ ㎡; The grammes per square metre of described Antiadhesive film is 15-20g/ ㎡.
In another specific embodiment of the present utility model, described Antiadhesive film is the mesh structure of hollow out.
The technical scheme that this utility model provides has adopted the carboxymethyl chitosan fabric nonwoven cloth owing to will protect the wound layer, thereby can embody ideal hemostasis, antibiotic, short and analgesic effect, and permeability and absorbent excellence.
