Abstract
The utility model belongs to the technical field of medical instrument, specifically an adhesive bandage used to embed the wound in order to relieve the pain and absorb the exudate. The adhesive bandage has the conformation of multilayer, wherein a bottom layer is covered by waterproof and breathable polymer films, whose surface is besmeared with a layer of medical adhesive (for example, pressure sensitive adhesive). The surface is pasted with a spongy layer containing chitosan or other adsorbed layers, wherein the surface of the spongy layer is further besmeared with an aquagel layer containing chitosan and release paper or membrane is arranged on the aquagel layer. The novel adhesive bandage is characterized in that a layer of aquagel material contains more than sixty percents of water in order to relieve the pain of the wound and the wound could not be conglutinated simultaneously; the exudate on the wound could be absorbed by the spongy layer under the aquagel layer and does not pollute clothes when the wound has some exudates. Moreover, the chitosan is contained in the aquagel layer, which has the effect of crude sterilization, thereby preventing the wound from being infected.
Description
Technical field
This utility model belongs to the medical devices technical field, is specifically related to a kind ofly can absorb the wound sepage, alleviates wound pain, does not contain the medicine composition and has the adhesive bandage (if say so, hydrogel layer must contain chitosan) of anti-microbial property.
Background technology
Adhesive bandage has obtained using widely in daily life, it mainly is made up of gauze or cotton fiber, but certain position when health, as finger, when being scalded, in wound healing process, can produce a large amount of sepages, at this moment used adhesive bandage generally can not absorb sepage usually, and is easy to be bonded on the wound, takes off and causes wound secondary wound when getting.The pain that alleviates wound in addition also is very important aspect of when treatment, but common adhesive bandage can't satisfy such requirement.
Summary of the invention
The purpose of this utility model be to provide a kind of be used to coat wound, and can absorption liquid, the adhesive bandage that eases the pain.
A kind of adhesive bandage that is used to coat wound that the utility model proposes is multiple structure, is made up of waterproof, gas-pervious bottom, medical adhesive layer, sepage adsorption layer and/or moisture protective layer and release layer successively.
In the above-mentioned adhesive bandage, described bottom adopts polymeric film, and adhesive layer adopts pressure sensitive adhesive.
In the above-mentioned adhesive bandage, described sepage adsorption layer adopts sponge, and moisture protective layer adopts hydrogel.
In the above-mentioned adhesive bandage, have at least one deck to contain chitosan in described spongy layer and the hydrogel layer.
In the above-mentioned adhesive bandage, described spongy layer sticks at the centre of polymeric film, and its size is less than the size of polymeric film, and the size of hydrogel layer is less than the size of spongy layer simultaneously.
In the above-mentioned adhesive bandage, the thickness of described hydrogel layer is 0.02-0.05mm.
This utility model adhesive bandage has one deck sepage adsorption layer (as spongy) and the moisture protective layer of one deck (as hydrogel structure); when wound produces sepage; the adsorption layer of adhesive bandage can absorb the sepage that wound produces; sepage can not flowed out; and when wound does not produce sepage, contain a certain amount of moisture content with the protective layer that skin directly contacts, it can provide a kind of growing environment of moistening to wound; the healing of accelerated in wounds alleviates the pain of wound simultaneously.Adhesive bandage can not be bonded on the wound yet in the wound recuperation, can prevent from effectively to take off that wound is subjected to secondary damage when getting.Contain the chitosan composition in sponge and the hydrogel layer in addition, chitosan has antibacterial action, can prevent wound infection.
Description of drawings
Fig. 1 is the vertical view of adhesive bandage.
Fig. 2 is the cross-sectional view of adhesive bandage.
Number in the figure: 1 is bottom, and 2 is medical adhesive layer, and 3 are the sepage adsorption layer, and 4 is moisture protective layer, and 5 is release layer.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described further
Be coated on medical pressure-sensitive adhesive on the urethane film uniformly, the spongy layer that will contain chitosan is bonded on the medical pressure-sensitive adhesive, and it is positioned at the center of polyurethane film, on sponge, apply the hydrogel layer that one deck contains chitosan then, hydrogel is positioned at the center of spongy layer, cover one deck mould release membrance or release paper at hydrogel layer then, cover its four limit, back just and and the justified margin of polyurethane film.When using, at first with mould release membrance or release low taking off, then hydrogel layer is covered the wound, because hydrogel layer contains himself moisture content more than 60%, when wound contacts with it, can alleviate the pain of wound, simultaneously with the ratio spongy layer of the size design of hydrogel little mainly be because when the wound generation sepage time, spongy layer can better absorb sepage, with the Thickness Design of hydrogel layer is 0.02-005mm, mainly be for when sepage produces, sepage permeate water gel layer is faster absorbed by spongy layer.
Claims (6)
