The present disclosure provides a thermal signal transmission patch electrically connected to an external controller, electronic component or signal source. The patch includes a substrate and a loop layer. The substrate is a sheet-shaped body. The loop layer is arranged on one side of the substrate. The loop layer includes a first loop layer and a second loop layer. The first loop layer includes a first contact, a second contact and a third contact. The second loop layer includes a fourth contact, a fifth contact and a sixth contact. An electrical connection mode of the first contact, the second contact, the fourth contact and the fifth contact electrically connected to the external controller or electronic component is changed, and the third contact and the sixth contact are electrically connected to the external signal source, so as to achieve a fast switching between electrotherapy and thermotherapy.

A cold/hot compress strip device with a quick replaceable compress strip and an efficient cold/hot switch includes a host machine and a flexible compress strip fixable to an affected part on a human body surface, and the host machine can pump the cooled cold water from its container into the compress strip and circulate the cold water in the compress strip for cold compress, or can quickly discharge the cold water in the compress strip, and drive a heating film on the compress strip to generate heat for hot compress, so as to achieve an efficient cold/hot switch, and the compress strip can be replaced quickly as needed. The application of the cold/hot compress strip device is very simple and practical.
