2. Description of the Related Art In recent years, endoscopes have been widely used in the medical field. A medical device such as an endoscope, which is particularly inserted into a living body, is in a sufficiently sterilized state so as to prevent infectious diseases. Also, after such medical equipment is used, body fluid or solid matter in the living body may adhere to the medical equipment, so after cleaning the medical equipment to remove the adhered material, store it in the autoclave device. It was kept in high temperature and high pressure steam for complete sterilization.

At the same time, since the ambient temperature condition is not sufficiently low (because the temperature around the semiconductor is not sufficiently low), the temperature of the semiconductor increases more and more and the characteristics of the semiconductor parts are deteriorated. May cause thermal damage to semiconductor parts, causing medical devices to malfunction. Further, there is a problem that characteristics of electrical components such as capacitors other than semiconductor components are deteriorated due to a rise in temperature due to heat-generating components.

The present invention has been made in view of the above points, and when used after autoclaving,

According to the first embodiment, the inside of the autoclave apparatus main body 12 is entirely monitored by the infrared camera 32, and if there is a locally high temperature, the temperature is detected as the maximum temperature detection circuit. Detect at 35. After this maximum temperature reaches the temperature below which it is judged that the door 14 may be opened, the door 14 is opened a few minutes later for safety, and it is prohibited to open it until then. Therefore, the medical device containing the electronic components such as the endoscope 13 after being taken out has dropped to a temperature at which there is no problem even if it is used.
