[0002] In the related art, functional kinesiology patch, also known as dressing, is a patch that acts on the surface of the human body. It acts on the skin or muscles of the human body through the drugs or chemical components added inside the dressing to relieve the discomfort of the human muscles.

[0003] For the cooling patch applied to the muscle on the skin surface, the principle of action on the human body is cold compress. Cold compress can cause the local capillaries of the human body to contract, reduce local congestion, reduce the sensitivity of nerve endings and relieve pain, reduce temperature and fever, reduce local blood flow, prevent the spread of inflammation and suppuration, and also dissipate heat conduction in the body, increase heat dissipation and lower body temperature.

[0004] The main problems with existing cold compress products are that the patch products have a simple structure, the medicine or coldness inside is released too quickly, and the patch products need to be replaced frequently. Frequent replacement of the patch will cause repeated adhesion to the skin surface, which can easily cause skin allergies. Utility Model Content

[0030] It is understandable that a hydrophilic gel layer 50 is disposed on the inner side of the elastic fabric 10 , and the hydrophilic gel layer 50 can lock the coldness in the patch, prolong the use time of the patch, and achieve a sustained release effect.

[0031] It can be understood that a cooling layer 30 is disposed inside the hydrophilic gel layer 50 , and a refrigerant is disposed inside the cooling layer 30 .

[0032] In some embodiments, Figure 1 As shown, the cooling patch 100 for the skin surface further includes a pressure-sensitive adhesive isolation film 60 , which is disposed between the cooling layer 30 and the drug layer 40 .

[0033] It is understandable that a pressure-sensitive adhesive isolation film 60 is provided between the refrigeration layer 30 and the drug layer 40. The pressure-sensitive adhesive isolation film 60 can prevent the refrigerant and the drug in the drug layer 40 from contacting prematurely, and can also prevent allergies from occurring in the affected area.

[0034] In some embodiments, Figure 1 As shown, the cooling patch 100 for the skin surface further includes a transdermal enhancer 70 . The transdermal enhancer 70 is disposed on the inner side of the drug layer 40 , and the outer circle of the transdermal enhancer 70 abuts against the inner circle of the adhesive 20 .

[0035] It can be understood that the skin penetration enhancer 70 can facilitate drug absorption and reduce damage to the skin.

[0036] In some embodiments, Figure 1 As shown, the cooling patch 100 for the skin surface further includes a release paper 80 , which is disposed on the inner side of the adhesive 20 .

[0037] It can be understood that the release paper 80 is used to maintain the stickiness of the adhesive 20 before use and to extend the storage time of the patch.

[0038] In some embodiments, Figure 1 As shown, the cooling patch 100 for the skin surface also includes an isolation ring 90, which includes an inner layer 91 and an outer layer 92. The inner layer 91 and the outer layer 92 are both arranged on the inner side of the elastic fabric 10, and the inner layer 91 and the outer layer 92 are arranged along the edge of the elastic fabric 10, and an adhesive 20 is arranged between the inner layer 91 and the outer layer 92.

[0039] In some embodiments, the component inside the drug layer 40 is diclofenac sodium, and the purity of diclofenac sodium is not less than 99%.

[0040] In some embodiments, a refrigerant is disposed inside the refrigeration layer 30 , and the refrigerant includes but is not limited to ice flakes and dry ice.

[0041] In some embodiments, the stretch fabric 10 is a camouflage stretch fabric 10 , and the color of the camouflage stretch fabric 10 is a starry sky camouflage color plus a snowflake pattern.

[0042] In some embodiments, the adhesive is a medical grade adhesive 20 .

[0043] Understandably, medical grade adhesives reduce damage to the skin.

[0044] When the cooling patch 100 for skin surface of the utility model is used, the release paper 80 is peeled off and the patch is attached to the human body surface through the adhesive 20. The cooling patch 10 for skin surface of the utility model achieves the effects of anti-inflammatory, antipyretic and analgesic by combining the refrigerant and the diclofenac sodium of the drug layer 40; the effective use time of the patch is extended by providing the hydrophilic gel layer 50; and the damage to human skin can be reduced by providing the pressure-sensitive adhesive isolation film 60 and the skin penetration enhancer 70.
