[0020] The medical cold compress patch body 1 utilizes multiple groups of air-permeable rubber strips 6 that are spaced apart in the hydrogel dressing layer 5. Through the micropores 61 on the lower surface and the left and right side surfaces of the air-permeable rubber strip 6, air circulates between the skin surface where the medical cold compress patch body 1 is attached and the outside, facilitating the enhancement of the air permeability effect of the medical cold compress patch body 1 itself, avoiding inflammation caused by the skin at the cold compress area being in a poorly ventilated and humid environment for a long time, and improving the practicality of the medical cold compress patch body 1.

[0024] As a preferred implementation manner, the polyethylene film 2 and the dust-proof film 21 serve as the protective films of the medical cold compress patch body 1. When in use, the polyethylene film 2 and the dust-proof film 21 are removed, and then the medical cold compress patch body 1 can be pasted and used.
