CN1044405 discloses and a kind ofly can absorb wound fluid, and can be with water transport to airborne binder.This binder be by thin film such as polyester, polyethylene as the protection backing, pasting one deck on the protection backing is that the hydrogel of skeleton is made with fabric or non-woven fabrics.The base material of hydrogel comprises sodium carboxymethyl cellulose, various polypropylene amine, polyacrylonitrile and acrylate copolymer etc.The shortcoming of this hydrogel is opaque.
CN1095916 discloses a kind of wound dressing that can absorb wound fluid.It forms the sealing top layer by polyurethane film and polymer filament net, absorbed layer is composited by mixture, the polypropylene fibre second layer of polypropylene fibre ground floor, hydrocolloid and superabsorbents, is the polymer base coat made of polyvinylpyrrolidone or polyvinyl alcohol and moisturely separates colloidal adhesive phase with skin directly contacts.This invention weighing-appliance has excellent water absorption, but it is to reach multi-layer compound structure that ideal intensity and water absorption design to have sacrificed and be beneficial to the transparency of observing wound.
CN2292547 discloses a kind of water absorption medical dressing of not sticking wound, and water accepting layer that it is made by the micropore non-woven fabrics that scribbles acrylic compounds water-absorbing resins film and the basic unit made from fabric or breathability non-woven fabrics form.This dressing except that have aforesaid opaque, do not intercept the shortcoming such as antibacterial, also lack ideal performances such as pliability that wound dressing should possess and elasticity, in addition, the residual monomer of acrylic resin usually has skin to stimulate or slight toxic and side effects.
Though existing these aquogel type wound dressings have solved problems such as absorption transudate, breathability, obstruct antibacterial, waterproof, wound comfort level, but for the intensity that increases hydrogel, the cohesive that strengthens hydrogel and waterproof and breathable notacoria, majority has all adopted fabric or non-woven fabrics as enhancement Layer, and has taked the complicated technology of MULTILAYER COMPOSITE.Like this, goods are opaque structure, have influenced the observation of wound healing situation.
The purpose of this utility model is to provide a kind of can absorb transudate, can intercept antibacterial; have transparent, ventilative, waterproof, not with characteristics such as tissue adhesion, pliability be good, be applicable to the hydrogel compounded dressing for wound of burn, scald, decubital ulcer, traumatic wounds protecting wound surface and treatment.
The technical solution of the utility model is as follows:
A kind of hydrogel compounded dressing for wound is the one side covering one deck gas permeable polymers film at hydrogel layer.
Further scheme is to be provided with adhesion layer between hydrogel layer and gas permeable polymers film.
Further the another side of scheme hydrogel layer covers release paper or the stripping film that one deck scribbles silicone.
Wherein, the overall dimensions unanimity of dressing, unified square, rectangle, circle or the elliptical shape of cutting into.
Wherein, the overall dimensions of gas permeable polymers film is consistent with release paper that scribbles silicone or stripping film, greater than the composite bed that all the other each layers constituted, the gas permeable polymers film be not coated with the medical pressure-sensing glue-line by the coated clear area of composite bed, the gas permeable polymers film with scribble the release paper of silicone or stripping film, composite bed can be made square, rectangle, circle or elliptical shape respectively.
Wherein, the thickness of hydrogel layer is 0.5 to 10mm; Preferred thickness is 2 to 4mm.
Wherein, the thickness of gas permeable polymers film is 25 to 100 microns; Preferred thickness is 25 to 50 microns.
Owing to adopt above scheme, the utlity model has good transparency, high-hydroscopicity, breathability, poisture-penetrability, but waterproof, can prevent wound infection, quicken recovery from illness.Be applicable to the protecting wound surface and the treatment of burn, scald, decubital ulcer and traumatic wounds.Pass through radiation sterilization in addition, but long term store.
