An apparatus, for a thermal vacuum therapy by using a suction cup on a skin of a patient, includes a heating unit disposed in the suction cup. The heating unit includes a heat core made of high heat conductive material and a heat retention sleeve made of low heat conductive material, wherein the heat core is wrapped by the heat retention sleeve and is arranged in such a manner that after the heat core rapidly stores heat energy, the heat retention sleeve is adapted for keeping the heat energy at the heat core so as to enable the heat core being gradually released heat within the suction cup during cupping treatment.本創作揭露一種用於保溫負壓治療的裝置,其中在所述保溫負壓治療中,會使用到將熱療罐置於病人的皮膚上進行治療,該裝置包括一個設置在熱療罐中的加熱單元。該加熱單元包括一個由高熱傳導性材料製成的熱蕊和一個由低熱傳導性材料製成的熱力保持套件,其中熱蕊被熱力保持套件所包圍,該熱蕊以此方式設置以在其快速儲存熱能後,該熱力保護套件適於保持該熱蕊中的熱能以使該熱蕊可在負壓罐熱療期間在負壓罐中持續釋放熱力。
