Description

A kind of special-shaped hydrogel wound dressing with drainage and application fixed function

Technical field

The invention belongs to medical instruments fields, and in particular to a kind of with the special-shaped hydrogel for draining and applying fixed function Wound dressing.

Background technique

Aerogel dressing is the novel wound dressing of one kind developed in recent years, compared with traditional dressing, water-setting Glue is not with wound adhesion, and will not fall off the impurity such as fiber on wound.And hydrogel has certain water content, is conducive to maintain wound The moist environment in face makes wound be not easy to form a scab, and wound can be promoted preferably to heal, mitigate the pain of patient.Certainly due to hydrogel Body contains moisture, and the ability for absorbing sepage is poor, the wound more for diffusate, will form hydrops, and dipping wound circumference is strong The skin of health.And because the submissive property of hydrogel is poor, when the surface of a wound applied to positions such as joint binding site, head, necks, nothing Method is sufficiently bonded with the surface of a wound, and medical staff is needed to carry out cutting splicing, cumbersome.

Summary of the invention

Goal of the invention: the present invention provides a kind of with drainage and applies the special-shaped hydrogel wound dressing of fixed function, One wet healing environment can be provided, and the more liquid body exudate of wound surface can be absorbed, keep periwound skin Drying property.When the surface of a wound applied to positions such as joint binding site, head, necks, can sufficiently the surface of a wound it be bonded, and operate letter It is single.

Technical solution: to realize the above-mentioned technical purpose, the invention proposes a kind of with drainage and applies fixed function Special-shaped hydrogel wound dressing, including supporting layer, hydrogel layer, water suction cushion layer, release paper, adhered layer.The wherein hydrogel Between the supporting layer and the water suction cushion layer, the lower surface of the hydrogel layer is placed in the supporting layer cavity layer, The hydrogel layer upper surface is mutually be bonded with the water suction cushion layer lower surface.The water suction cushion layer upper surface again with adhered layer following table Face is mutually bonded, and the release paper is covered on adhered layer lower surface along the water absorption pad outer rim.

Specifically, the supporting layer lower surface is mutually applied with hydrogel upper surface, hydrogel layer lower surface and water suction cushion layer Compound stickup, then it is mutually compound by water suction cushion layer and adhered layer.The water suction cushion layer central area (being not limited to central area) is engraved Sky, fretwork area are less than the surface area of hydrogel layer.Water suction cushion layer hollow out window edge and the spacing at hydrogel layer edge be not small In 1mm.

Further, water absorption pad outer ring area is greater than the surface area of hydrogel layer, water suction cushion layer outer edge and hydrogel layer side The spacing of edge is 1-30mm.

The beneficial effects of the utility model are: water suction cushion layer can absorb extra sepage, the dry of periwound skin is kept Dry property.Water suction cushion layer central area (the being not limited to central area) hollow out, utilizes the characteristic that hydrogel oneself height is transparent, shape At visual windows, conducive to the variation of the observation surface of a wound.

Further, the stickup surface layer is greater than water suction cushion layer outer ring area, water suction cushion layer outer edge and adhered layer side The spacing of edge is not less than 5mm.

Taking the beneficial effect of above-mentioned further scheme is: making with the special-shaped hydrogel wound for draining and applying fixed function Hurt dressing with tack, does not need the fixation of second level dressing.

Based on the above technical solution, the utility model can also do following improvement.

Further, the hydrogel layer shape is three lobeds or other combined shapeds, water suction cushion layer and adhered layer and water-setting The shape of glue-line matches.

Taking the beneficial effect of above-mentioned further scheme is: the wound applied to positions such as joint binding site, head, necks It when face, can be sufficiently bonded with the surface of a wound, carry out cutting splicing woth no need to medical staff, it is easy to operate simple.

Further, the hydrogel layer upper surface lobed base portion is equipped with groove, and trench depth is less than the thickness of hydrogel layer.

Taking the beneficial effect of above-mentioned further scheme is: because hydrogel layer has certain thickness, when as larger such as bending angle, Because of the effect of surface tension, bending place hydrogel layer cannot can reduce bending place surface tension equipped with groove, make with skin attachement Wound dressing preferably with skin attachement, forms closed moist environment.

Further, the support layer surface product, which is greater than, pastes surface layer, sinks with hydrogel layer contact site into cavity, Submergence depth is identical as hydrogel thickness, and shape and the water-setting layer shape at sinking position match.In hydrogel layer arc groove Position, equipped with the strip bulge to match.

Further, the supporting layer has support using any one in PET, PVC, PP with a thickness of 0 .1~2mm Ability.

Taking the beneficial effect of above-mentioned further scheme is: providing support for wound dressing, facilitates operation, and protect wound Dressing is indeformable during transportation.

Further, along the outer ring of the water absorption pad, in adhered layer lower surface, a circle barrier paper, the width of barrier paper are pasted It spends identical as the spacing of water suction cushion layer outer edge and adhered layer edge.

Taking the beneficial effect of above-mentioned further scheme is: facilitating the taking-up of wound dressing and operates with.

The utility model has the size for the special-shaped hydrogel wound dressing for draining and applying fixed function can be according to reality Border needs to be adjusted.
