Abstract

The utility model discloses a hydrogel patch, which comprises a patch body, wherein the patch body is divided into a sodium carboxymethylcellulose hydrogel layer and an adhesive layer, the adhesive layer is fixed at the bottom of the sodium carboxymethylcellulose hydrogel layer through glue, the adhesive layer is in an annular structure and is arranged on the outer side of the sodium carboxymethylcellulose hydrogel layer, and a waterproof layer is fixed on the outer wall of the patch body through glue, so that the problems that the patch does not have cohesiveness, the patch can be adhered to a wound and the patch cannot be directly and manually manufactured into different sizes are solved.

Description

Hydrogel plaster

Technical Field

The utility model relates to a patch, in particular to a hydrogel patch.

Background

The dressing refers to auxiliary materials used for articles besides main materials, and mainly refers to hemostatic gauze (usually medical absorbent gauze). Traditional dressing often adopts the gauze to wound treatment, will condense together with the wound after the in-process gauze that uses has absorbed the sepage of wound, will stimulate the wound when later stage is torn gauze open and is changed dressings for the wound resumes slowly, and gauze etc. are applied ointment or plaster itself and do not have the cohesiveness, so still need to adopt the bondings such as sticky tape to fix the sticky tape very inconvenient when fixed gauze, and current application still need cut out into suitable size according to the difference needs manual work of wound when using and just can use, if do not have the scissors outdoors, will become very inconvenient to the tailorring of applying ointment or plaster.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a hydrogel patch, which solves the problems that the patch does not have cohesiveness, the patch can be adhered with a wound and the patch cannot be directly and manually made into different sizes.

The technical purpose of the utility model is realized by the following technical scheme:

the hydrogel patch comprises a patch body, wherein the patch body is divided into a sodium carboxymethylcellulose hydrogel layer and a pasting layer, the pasting layer is fixed at the bottom of the sodium carboxymethylcellulose hydrogel layer through glue, the pasting layer is of an annular structure and is arranged on the outer side of the sodium carboxymethylcellulose hydrogel layer, and a waterproof layer is fixed on the outer wall of the patch body through glue.

Adopt above-mentioned technical scheme, when needs use the application to handle the wound, aim at sodium carboxymethylcellulose hydrogel layer with the wound earlier, fix sodium carboxymethylcellulose hydrogel layer in the wound through the subsides layer of fixing in the sodium carboxymethylcellulose hydrogel layer outside, can supply moisture for the surface of a wound through sodium carboxymethylcellulose hydrogel layer, through maintaining the moist healing environment a little, accelerate the surface of a wound healing, improve the healing quality, prevent that sodium carboxymethylcellulose hydrogel layer from absorbing the moisture that the external world contains the bacterium and can cause the infection to the wound through fixing the waterproof layer outside sodium carboxymethylcellulose hydrogel layer.

Preferably, the specification of the application body is 6cm by 7cm, the application body comprises a first application, a second application, a third application and a fourth application, and each joint of the application body is provided with a serrated cut convenient for tearing.

Adopt above-mentioned technical scheme, can select different applications according to the size of wound, select good application accessible cockscomb structure incision will apply ointment or plaster the tear for need not cutting out the convenience that has improved the use adopting the scissors.

Preferably, the bottom of the sticking layer is provided with a plurality of medical pressure-sensitive adhesives, and plastic stickers are stuck on the medical pressure-sensitive adhesives.

Adopt above-mentioned technical scheme, medical pressure-sensitive adhesive has that the adhesion is strong, heat-resisting, cold-resistant, colorless transparent, little advantage such as to environmental pollution, through medical pressure-sensitive adhesive, is convenient for paste the body of applying ointment or plaster and paste in wound department, when applying ointment or plaster the body and take off from the human body, does not have residual viscous substance on the skin, has guaranteed the viscidity of pasting the layer through the plastics sticker, prevents that medical pressure-sensitive adhesive from exposing for a long time and makes viscidity reduce in the space.

Preferably, the waterproof layer is a polyurethane film.

Adopt above-mentioned technical scheme, the waterproof layer main part is a transparent medical film, and the waterproof layer is pasted on applying ointment or plaster the body through transparent glue, has guaranteed the waterproof nature of applying ointment or plaster the body.

Preferably, the glue is a polypropylene adhesive.

By adopting the technical scheme, the polypropylene adhesive is a material which is completely transparent, has no pungent smell, is nontoxic and waterproof, and all layers of the application body are connected through the polypropylene adhesive.

Detailed Description

The following description is only a preferred embodiment of the present invention, and the protection scope is not limited to the embodiment, and any technical solution that falls under the idea of the present invention should fall within the protection scope of the present invention. It should also be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model.

See fig. 1 to 3, a aquogel is applied ointment or plaster, including applying ointment or plaster body 1, apply ointment or plaster body 1 and divide into sodium carboxymethylcellulose hydrogel layer 2 and paste layer 3, paste layer 3 and fix in sodium carboxymethylcellulose hydrogel layer 2 bottom through glue, glue adopts the polypropylene adhesive, the polypropylene adhesive is a full transparent, no pungent smell, nontoxic and waterproof material, thereby will apply ointment or plaster body 1's each layer through the polypropylene adhesive and connect.

Paste layer 3 and paste layer 3 setting in the 2 outsides of sodium carboxymethylcellulose hydrogel layer for annular column structure and, it is provided with a plurality of medical pressure-sensitive adhesive to paste layer 3 bottom, medical pressure-sensitive adhesive has that the adhesion is strong, it is heat-resisting, cold-resistant, colorless transparent, advantage such as little to environmental pollution, through medical pressure-sensitive adhesive, be convenient for paste body 1 of applying ointment or plaster in wound department, when applying ointment or plaster body 1 and take off from the human body, no residual viscous substance on the skin, it has plastics sticker 10 to paste on medical pressure-sensitive adhesive, the viscidity of pasting layer 3 has been guaranteed through plastics sticker 10, prevent that medical pressure-sensitive adhesive from exposing for a long time in the space and making viscidity reduce

When needs use the application to handle the wound, aim at sodium carboxymethylcellulose hydrogel layer 2 with the wound earlier, tear plastics sticker 10 away, fix sodium carboxymethylcellulose hydrogel layer 2 in the wound through medical pressure sensitive adhesive, can replenish moisture for the surface of a wound through sodium carboxymethylcellulose hydrogel layer 2, through maintaining the little wet healing environment of surface of a wound, accelerate the surface of a wound healing, improve healing quality.
