PROBLEM TO BE SOLVED: To easily recognize the state of sterilizing process for medical parts by providing an indicator for showing to a user whether the parts or components complete heat cycle after use or not in addition to the frequency of use/heat cycle. SOLUTION: An indicating element shaped like a plate 12 having two indicating areas 14, 16 such as a red area and a green area is provided for recording a heat cycle, and the plate 12 can be moved by a memory metal spring 20 changing in its shape according to a temperature. In the state before the heat sterilization for medical parts, the spring 20 is contracted so that the plate 12 is put in a first indicating position, so the red area 14 can be seen through a window 18. Heat sterilization is applied to the medical parts, and when a temperature passes a prescribed threshold so that the spring 20 is elongated, the plate 12 is put in a second indicating position so that the green area 16 can be seen through the window 18. At this time, the movement of the plate 12 is transmitted to a monitor unit 19, and the frequency of the sterilization cycle is stored in a memory 23. |
