PROBLEM TO BE SOLVED: To provide, for example, a sanitary medical instrument.SOLUTION: The medical instrument such as a boring-pain relieving device (10) includes: a Peltier element (100) having an endothermic surface (1001) and a heat-radiating surface (1002) a latent heat storage agent (16) disposed on the heat-radiating surface, while retaining a thermal contact state therewith and housings (11F and 11R) that store the Peltier element and the latent heat storage agent, with a heat-conductive member (18), as a cooling part, exposed therefrom, the heat conductive member covering the endothermic surface or at least a part of the endothermic surface. A cover (DC1) for covering the cooling part is detachably configured.COPYRIGHT: (C)2015,JPO&INPIT【課題】例えば、衛生的な医療機器を提供する。【解決手段】例えば、穿刺痛緩和装置(10)等の医療機器は、吸熱面(1001)と放熱面(1002)とを有するペルチェ素子(100)と、前記放熱面に熱的接触状態を保って配置された潜熱蓄熱剤(16)と、前記吸熱面又は前記吸熱面の少なくとも一部を覆う熱伝導性部材(18)が冷却部として露出した状態で前記ペルチェ素子及び前記潜熱蓄熱剤を収納する筐体(11F,11R)とを備え、前記冷却部を覆うカバー(DC1)を取り付け可能に構成される。【選択図】図2
