[0002] Cold compress is a relatively economical cold compress therapy through physical cooling. Medical cold compress patch is a plaster-like product improved from the traditional cold compress method. It is usually composed of a backing layer and a gel layer. With the help of the moisture contained in the gel layer and the heat absorption and heat removal of the natural cooling ingredients during vaporization, it can effectively cool the patient's skin surface locally, thereby achieving the effects of cold compress pain relief, percutaneous absorption, and sustained-release drug delivery.

[0003] The utility model with patent application publication number CN 211271586 U discloses a medical cold compress patch. When using the patch, two tear-off sheets can be pulled to both sides to drive the release paper layer and the adhesive layer to open to both sides respectively, and the release paper layer is removed from the outside of the cold compress patch, and then the protective layer is removed from the adhesive layer, and then the cold compress patch can be attached to the affected area;

[0004] In the above scheme, the adhesive layer is used to adhere to the human skin. Using the adhesive layer to adhere the cold compress patch will not only cause pain to the patient when removing it, but the adhesive will also remain on the skin, and the patient's real-time body temperature changes cannot be known in time after the cold compress.

[0012] As a preferred solution of the utility model, the reinforcing member includes extensions arranged on both sides of the protective layer, and the cross-sections of the two extensions are semicircular.

[0013] As a preferred solution of the utility model, the opposite sides of the two extension parts are fixedly connected to the left and right sides of the protective layer respectively, the two extension parts are also polyethylene films, the tops of the two extension parts are fixedly connected with medical silicone strips, and the two ends of the two medical silicone strips are closed.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, the release paper can be easily torn off through the tear strip, and the cold compress gel can be pasted on the patient's skin through its own adhesion to avoid adhesive residue on the skin surface. At the same time, the medical silicone strips closed and connected on both sides are pressed on the surface of the skin to discharge the internal air, which can be adsorbed on the patient's skin, thereby enhancing the stability of the cold compress.

[0016] 2. In the present invention, the color of the color-developing filling changes due to the influence of temperature, so as to promptly remind the patient of the change in body temperature, provide effective feedback on the temperature, and facilitate intervention.

[0025] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0026] A backing-free, high-water-content medical color-developing cold compress patch comprises a protective layer 1, a cold compress layer 2 is arranged on the top of the protective layer 1, reinforcement pieces 5 are arranged on the left and right sides of the protective layer 1, the cold compress layer 2 comprises a cold compress gel 201 arranged above the protective layer 1, a water-absorbing layer 202 is bonded to the bottom of the cold compress gel 201, a side of the water-absorbing layer 202 away from the cold compress gel 201 is fixedly connected to the top of the protective layer 1, a color-developing filler 203 is filled in the middle of the cold compress gel 201, and the color of the color-developing filler 203 can change due to temperature changes, so as to facilitate real-time observation of the patient's body temperature.

[0027] like Figure 3As shown, the protective layer 1 is made of polyethylene film, the water-absorbing layer 202 is made of a polymer water-absorbing resin, the color-developing filler 203 is a temperature-sensitive color-changing microcapsule, and the cold compress gel 201 is made of a hydrogel mixture. The water-absorbing layer 202 can absorb sweat on the skin surface without making the skin stuffy and damp.

[0028] like Figure 1 , Figure 2 As shown, a release paper 3 is bonded to the top of the cold compress gel 201, a tear strip 4 is fixedly connected to the right side of the release paper 3, and the reinforcement member 5 includes extensions 501 arranged on both sides of the protective layer 1, the cross-section of the two extensions 501 is semicircular, and the opposite sides of the two extensions 501 are respectively fixedly connected to the left and right sides of the protective layer 1, and the two extensions 501 are also polyethylene films. The tops of the two extensions 501 are fixedly connected with medical silicone strips 502, and both ends of the two medical silicone strips 502 are closed. The strips 502 are attached to the skin, and a certain negative pressure is generated to adsorb the medical silicone strips 502 on the skin.

[0029] The working process of the utility model is as follows: when in use, the tear strip 4 can be used to quickly tear off the cold compress gel 201, and the cold compress patch is attached to the patient's skin by utilizing the stickiness of the cold compress gel 201 itself, which will not cause pain to the patient when tearing it off, and no residual glue will remain on the skin surface. Subsequently, two medical silicone strips 502 are attached to the skin, and they are gently pressed to expel the air inside, thereby generating a certain negative pressure to adsorb the medical silicone strips 502 to the skin, thereby strengthening the stability of the cold compress patch and preventing it from falling off during use. The water-absorbing layer 202 can absorb sweat on the skin surface and will not make the skin stuffy and damp. At the same time, the color-developing filling 203 can change color due to changes in temperature, thereby facilitating real-time observation of the patient's body temperature.
