Is done. The ID number of the endoscope 2 is confirmed, and the cleaning state of the endoscope 2 is confirmed and recorded.

  (Step 14) If it is determined that the object has not been cleaned, a prohibition measure for prohibiting the use of the object to be sterilized, that is, the endoscope 2 is executed. As a prohibition measure, for example, the monitor 6 displays a message indicating that it has not been cleaned or prohibits its use. Even when the date and time of cleaning have passed the specified time limit, it may be determined that the cleaning has not been performed in consideration of safety.

  (Step 15) When it is determined that no washing is performed, the subsequent operation command from the operation unit 5 is invalidated so that the operation of the endoscope apparatus body 1 is not performed. Alternatively, the endoscope apparatus body 1 is turned off (shut down). Thus, the monitor 6, the calculation unit 9, the power supply unit 13, and the like constitute a prohibition measure execution unit that prohibits use of the uncleaned endoscope 2.

  (Step 16) When it is confirmed that the endoscope has been cleaned, a program necessary for the operation such as the sequence program is developed, and the endoscope apparatus body 1 is started normally.

  STEP: 17 When the endoscope apparatus main body 1 is completely activated, the IC tag reader / writer 8 writes “endoscope = used” along with the date and time on the IC tag 15. The read data of the IC tag 15 and the data written in the IC tag 15 are recorded in the storage unit 12 in association with the ID number and date / time. Regarding the medical practice described later, the content and implementation state of the medical practice are recorded in the storage unit 12 in association with the ID number.

  When the endoscope 2 is connected to the endoscope apparatus main body 1 and no medical practice is performed, or the patient's medical chart information is read into the endoscope apparatus main body 1 but the actual medical practice is performed. If the medical device was not performed, the implementation state in which the medical practice was not performed is recorded in the storage unit 12, and when the endoscope apparatus main body 1 is turned on again, the ID number of the IC tag 15 and The implementation state of the medical practice may be collated, and the determination of whether the endoscope 2 is cleaned or not cleaned may be skipped. For safety reasons, once connected to the endoscope apparatus main body 1, “endoscope = uncleaned” regardless of whether the medical practice was performed or the medical practice was not performed. Also good.

  Further, after the medical practice is performed, the writing of the IC tag 15 is fixed as “endoscope = not washed” regardless of whether it is finished or not. Is also “endoscope = not washed”.

  (Step 18) Examination and treatment using the endoscope 2 are performed. The used endoscope 2 is cleaned by the endoscope cleaning device 3 and used repeatedly.

  The consistency of data can be confirmed by referring to the use history of the endoscope 2 recorded in the storage unit 12 and the cleaning record recorded in the storage unit 22 based on the ID number. Good.
