The invention discloses a hydrothermal
blanket comprising a
cushion body, a heating device, a liquid inlet
pipe and a liquid outlet
pipe. One end of the liquid inlet
pipe and one end of the liquid outlet pipe are both communicated with the heating device, and the other end of the liquid inlet pipe and the other end of the liquid outlet pipe are both communicated with the
cushion body. The hydrothermal
blanket further comprises a driving device driving liquid to flow in a circulating mode. The
cushion body comprises a first layer body and a second layer body which are both made of insulation and waterproof materials, wherein the periphery of the first layer body and the periphery of the second layer body are mutually sealed and pressed, the
two layer bodies are mutually pressed to form a plurality of pressing points and a first pressing line, gaps are formed among the pressing points to form flow channels for fluids to flow, and the pressing line divides the flow channels into a liquid inlet unit and a liquid outlet unit. No pipe bodies are distributed in the whole cushion body, discomfort cannot be caused, and the hydrothermal
blanket can be folded at will, and is convenient to carry and long in service life; and the flow channels are multi-directional, liquid can flow at will in the flow channels, blocking phenomena of
heat transfer cannot occur, and uniform temperature distribution of the whole blanket body is guaranteed.
