[problem] outer surface heat exchange target is not a flat, for example in contact with the body type and physique is recessed different body sites to transfer heat, providing a heat exchange means can be maintained so as not to miss was allowed to transfer heat it was an object of the present invention to be. A placed on the heat exchanged in the heat exchange object and the heat exchange means 10 for heat exchange, in which the outer bag body 20 forms a housing, is interchangeably enclosed within said outer bag a bag body 30, and a contact promoting means for enlarging the contact area between said heat exchange means and the heat exchanger object, the inner bag 30 is deformable wherein the heat transfer medium 33 made of a fluid, contact promoting means includes a gas 31, made of a bag containing a gas flow control unit 27, the gas contained between the the inner bag and the heat exchanged, gas flow control means 27, the heat exchange means 10 There at least a portion of the gas 31 pressurized by being placed was extruded from the bag, the gas was extruded be controlled not to flow back. .FIELD 3【課題】 外面が平坦でない熱交換対象、例えば体型や体格が異なる遺体の窪んだ部位に接触して熱を伝達させ、伝達させた熱を逃さないように維持できる熱交換手段を提供することを課題とした。【解決手段】 熱交換対象に載置されて、熱交換対象と熱交換させる熱交換手段10において、外殻をなす外袋体20と、前記外袋体の中に交換可能に内包される内袋体30と、前記熱交換対象と前記熱交換手段との接触面積を拡大させる接触促進手段とを含み、前記内袋体30は、流動体からなる伝熱媒体33を含み変形可能とされ、接触促進手段は、気体31と、気体流制御手段27とを含んだ袋体からなり、気体が内袋体と熱交換対象との間に含まれ、気体流制御手段27が、熱交換手段10が載置されることにより加圧された気体31の少なくとも一部を袋体から押し出させ、押し出させた気体が逆流しないように制御させる。【選択図】図3
