Other structures such as the cushion layer of the skin protection patch are the same as those of the embodiment shown in fig. 1A to 1D, and will not be described here again.

As shown in fig. 3, which is a schematic diagram illustrating the use of a skin protection patch 300 according to one embodiment, the protective layer below the base layer is torn off to expose the adhesive on the lower surface of the base layer 310, and then the skin protection patch is attached to the skin site where injection is required, which is equivalent to positioning the injection site, and the skin protection patch is stably fixed on the skin under the action of the adhesive, so that the pharmaceutical composition in the cushion layer 330 can permeate the skin surface to anesthetize or relieve pain; then, the cover layer 320 is peeled off from the base layer 310 from one edge or opening portion of the cover layer 320, at this time, the cover layer 320 and the cushion layer 330 are partially separated from the base layer 310, but not completely separated from the base layer 310, so that all or at least a part of the hollowed-out area of the base layer 310 is exposed, then, the skin is sterilized, injected or the like according to the normal requirements, after the injection is completed, the cover layer 320 and the cushion layer 330 are restored to be connected with the base layer 310, and the pharmaceutical composition in the cushion layer 330 can continuously permeate to the skin surface to continuously perform anesthesia or pain relief on the skin. When the thickness of the cushion layer 330 is greater than the overall thickness of the base layer 310, the cushion layer 330 applies a certain pressure to the skin, so that the skin is more tightly contacted with the cushion layer, which is beneficial to better stopping bleeding or pain. When the wound no longer needs protection, the skin protection patch can be torn off from the skin as a whole.

In one embodiment, the skin protection patch may be used to protect the skin in a manner that covers skin wounds and to enable inspection and repeated application of wounds by repeated opening and closing of the cover layer.
