PROBLEM TO BE SOLVED: To provide a heat control method and heat control device effectively utilizing a common Peltier device both for a freezing operation and for thermotherapy if the freezing operation and the thermotherapy are applied in this order to the treatment of an affected area in an organism tissue of the human body, etc.SOLUTION: When a switch mechanism 300 is switched so that the direct voltage of a stabilized DC power supply 310 is applied to left and right feet members 224 and 225 of the Peltier device 220 with the left foot member as the positive electrode and the right foot member as the negative electrode, the Peltier device exhibits the endothermic function in the left and right foot members to absorb heat from the organism tissue 100 via a piezoresistance body 230. When the switch mechanism 30 is switched so that the direct voltage is applied to the left and right foot members of the Peltier device with the right foot member as the positive electrode and the left foot member as the negative electrode, the Peltier device exhibits the heating function in the left and right foot members to heat the affected area in the organism tissue via the piezoresistance body.COPYRIGHT: (C)2008,JPO&INPIT【課題】人体等の生体組織の患部の治療に凍結手術及び温熱療法をこの順で併用するにあたり、当該凍結手術及び温熱療法の双方に共通のペルチェ素子を有効に活用してなる熱制御方法及び熱制御装置を提供する。【解決手段】直流安定化電源310の直流電圧が、ペルチェ素子220の左右両側足部材224、225に、左側足部材を正側電極とし、右側足部材を負側電極として、印加されるように、切り換えスイッチ機構300が切り換えられると、ペルチェ素子は、左右両側足部材でもって、吸熱機能を発揮して、圧抵体230を介し生体組織100の患部から吸熱する。直流安定化電源の直流電圧が、ペルチェ素子の左右両側足部材に、右側足部材を正側電極とし、左側足部材を負側電極として、印加されるように、切り換えスイッチ機構が切り換えられると、ペルチェ素子は、左右両側足部材でもって、加熱機能を発揮して、圧抵体を介し生体組織の患部を加熱する。【選択図】図1
