When ice or heat is needed, an ice bag or a hot water bag can also be placed inside the placement bag 116; When tearing off the first medical adhesive patch 201 and the second medical adhesive patch 301, pure water is sucked into the syringe, the needle is installed, the needle is passed through the rubber stopper 404, and then water is injected into the peeling curved tube 401. The peeling curved tube 401 expands after being injected with water. When expanding, the peeling curved tube 401 gradually approaches a circle, and the bonding area between the lower surface of the peeling curved tube 401 and the skin gradually decreases. At the same time, the first medical adhesive patch 201 and the second medical adhesive patch 301 nearby are lifted, so that the bonding area between the skin and the first medical adhesive patch 201, the second medical adhesive patch 301 and the peeling curved tube 401 is reduced, thereby facilitating the tearing and replacement of the first medical adhesive patch 201 and the second medical adhesive patch 301.
