The utility model discloses a moist dressing of aquogel for by the water -soluble nevertheless water insoluble cross linked polymer that has three -dimensional net structure that expands, can absorb wound exudate, and have waterproofly breathe freely, hinder that the fungus is preserved moisture, the not adhesion surface of a wound, travelling comfort are strong, convenient to use's advantage, can extensively be applicable to the moist nursing of human each position operation incision and the various surface of a wound such as burn and scald or baby's navel cord.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of hydrogel moist dressing.
Background technology
Wound care mainly comprises two parts: use traditional dressing in dry environments and use high-end dressing in moistening healing environment.Wet wound healing is the theory of scientists through 30 or 40 years Researching and practicing formation, and namely epithelial cell could must grow fast under moistening environment, and wound healing rate when moistening is accelerated.
The dressing such as glue, polymeric membrane and artificial skin, all belong to the dressing of wet wound healing type, there is the interaction of multiple pattern between dressing and wound, as absorbed sepage and noxious substance, permission gas exchange, and are the desirable environment of healing creation one.Moistening healing is the main trend of following trauma care and Wound care, therefore creates moistening healing environment, promotes wound healing, reduces to infect probability, the generation of minimizing cicatrix and reduce and look after the primary condition that cost etc. is an advanced dressing.And the volume production technology of the inner face material of dynamical absorbing material, high bio-compatibility, water-proof antibiotic coating surfacing and advanced person determines the successful key of advanced dressing commercialization.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and can absorb wound fluid, waterproof and breathable, the moisturizing of resistance bacterium, adhesion wound surface, comfortableness hydrogel moist dressing strong, easy to use fast.
For solving the problems of the technologies described above, the technical solution of the utility model is:
This utility model provides a kind of hydrogel moist dressing, comprising: hydrogel applies core, and be arranged on described hydrogel apply core upper surface protective layer and be arranged on the release paper that described hydrogel applies core lower surface; Described hydrogel applies core and comprises the breathable films connected successively from top to bottom and carry material and hydrogel layer; Described protective layer comprises substrate, PU thin film and medical pressure-sensing glue-line, and described substrate, described PU thin film are connected successively from top to bottom with described medical pressure-sensing glue-line.
Wherein, in above-mentioned hydrogel moist dressing, described release paper is provided with the tearing notch that is conveniently opened use.
Wherein, in above-mentioned hydrogel moist dressing, described substrate is any one in mould release membrance, Ge Laxin and silicone oil paper.
Wherein, in above-mentioned hydrogel moist dressing, the consistent size of described substrate and described release paper, the consistent size of described medical pressure-sensing glue-line and PU thin film, described hydrogel layer and described breathable films carry the consistent size of material.
Have employed technique scheme, the beneficial effects of the utility model are:
Compared with prior art, hydrogel moist dressing of the present utility model, for being water-swellable but the water-fast cross linked polymer with three-dimensional net structure, the hydrophilic group in dressing structure can be utilized in use procedure to absorb wound exudate and evacuation of pus, form the semi-solid material of similar gels, be attached to wound base portion, prevent wound dehydrates, provide and maintain the moist environment of wound healing; Utilize its viscosity to form the healing environment of wound surface enclosed, prevent bacterial micro-organism from invading, prevention infection; And waterproof and breathable, the moisturizing of resistance bacterium.The moist nursing of partes corporis humani position operative incision and the various wound surface such as burn and scald or infant umbilical cord can be widely used in.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hydrogel moist dressing of this utility model embodiment;
Wherein, 1 is substrate; 2 is PU thin film; 3 is medical pressure-sensing glue-line; 4 carry material for breathable films; 5 is hydrogel layer; 6 is release paper; 7 is tearing notch.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of this utility model, but can not be used for limiting scope of the present utility model.
As shown in Figure 1, the hydrogel moist dressing of this utility model embodiment comprises: hydrogel applies core, and be arranged on hydrogel apply core upper surface protective layer and be arranged on the release paper 6 that hydrogel applies core lower surface.Wherein, hydrogel applies core and comprises the hydrogel layer 5 that the breathable films connected successively carries material 4 and formed by the cross linked polymer of glycerol, Polyethylene Glycol, polyvinylpyrrolidone and water from top to bottom, hydrogel layer 5 and breathable films carry the consistent size of material 4, and are combined by crosslinked.Protective layer comprises substrate 1, PU thin film 2 and medical pressure-sensing glue-line 3; substrate 1, PU thin film 2 are connected successively from top to bottom with medical pressure-sensing glue-line 3; namely be pasted together successively from top to bottom, substrate 1 can be any one in mould release membrance (base material is PE/PET composite), Ge Laxin (base stock is Ge Laxin) and silicone oil paper (abbreviation release paper).Release paper 6 is provided with the tearing notch 7 that is conveniently opened use.Namely in this enforcement, hydrogel moist dressing comprises the substrate 1, PU thin film 2, medical pressure-sensing glue-line 3, the breathable films that connect successively and carries material 4, hydrogel layer 5 and release paper 6, the consistent size of substrate 1 and release paper 6, the consistent size of medical pressure-sensing glue-line 3 and PU thin film 2, hydrogel layer 5 and breathable films carry the consistent size of material 4.Hydrogel layer 5 and breathable films are carried material 4 and are combined by crosslinked, release paper 6 is provided with the tearing notch 7 that is conveniently opened use, cover the outer surface of hydrogel layer 5, its bonding partially do not contacted with hydrogel layer 5 is on the PU thin film 2 scribbling medical pressure-sensitive adhesive 3, and substrate 1 and PU thin film 2 are pasted together.
In one embodiment, the size of substrate 1 and release paper 6 is all greater than the size of hydrogel layer 5, and be arranged to be with square, the trapezoidal or arc of fillet with one end, between substrate 1 and release paper 6 with the square, trapezoidal of fillet or arch section without the need to precoating pressure sensitive adhesive.Rectangle, the square or circular of hydrogel moist dressing entirety in band fillet, different according to the true form of wound surface, the rectangle of different specification size, square or circular can be designed to, such shape processing is more convenient, and band fillet design is also to prevent dressing alice or crimping in packaging or use procedure.
