Fever cooling patch attached to skin at zero distance

A fever cooling patch attached to the skin at a zero distance sequentially comprises a fever cooling patch body, a heat insulating layer and a temperature display patch from bottom to top. The temperature display patch comprises a lower surface, an upper surface, a color developing material and a plastic film layer. The portion between the upper surface and the lower surface is coated or filled with the color developing material, and meanwhile the edges of the upper surface and the lower surface are sealed. The outer side of the lower surface is coated with non-setting adhesive and then covered with a plastic film. The fever cooling patch body comprises a backing layer, a gel layer and a plastic film layer. The backing layer is of an elastic structure and located on the uppermost layer, the backing layer is evenly coated with the gel layer, the gel layer is completely covered with the plastic film layer, and the edges of the backing layer, the gel layer and the plastic film layer are not sealed. The display process of the fever cooling patch is reversible, and the fever cooling patch can be attached to the skin of the human body at the zero distance.
