Description

      The present invention relates to a thermal treatment apparatus for treating a disease which heats an affected area to 38 to 46 ° C.

      Conventionally, a thermal treatment apparatus (see, for example, Patent Document 1) uses a pump to circulate and transfer a latent heat storage medium to a rubber hollow radiator, but has a small spherically expanded contact area due to the rubber hollow radiator. Therefore, in order to heat the affected area, it is necessary to enlarge the hollow rubber heat dissipating section. In addition, in order to insert the hollow rubber heat dissipating unit into the body, a large surgical operation of a surgical wound is required, and the pain after the operation is large and the administration of an analgesic is required. Furthermore, in thermotherapy, when heat-resistant protein is produced, cancer cells also become heat-resistant, so treatment will be interrupted for several days until heat-resistant protein decreases, but surgery is necessary to remove the device. As a result, there is a problem that the device remains attached even during a period when no treatment is given, and the patient can not act freely. In addition, there is a problem that after the treatment is completed, surgery is required to take out the hollow rubber heat dissipating part, which places a heavy burden on the patient.
