- an inspection mode is selected to determine whether the endoscope 10 mounted in step S304 is leak-tested in an automatic mode or a manual mode.
- step S306 the procedure proceeds to step S306 to read the RFID tag 30 of the mounted endoscope 10 using the RFID module 192, and the RFID tag 30 in step S308.
- the endoscope information corresponding to the unique identification information read out from is automatically selected.
- step S316 select the type of endoscope for leak inspection.
- endoscope information according to the selected endoscope is automatically selected. This is suitable for the situation where the operator knows the type or serial number of the endoscope on which the operator is equipped when the type or quantity of the endoscope is provided in a small amount.
- step S320 the air is pressurized to the inner conduit of the endoscope 10 up to the pressurized pressure set in the controller 102.
- step S322 the inside of the pipeline is stabilized to reach and maintain the set pressure for a predetermined time.
- the pressure of the inner duct of the endoscope 10 is measured at unit time intervals through the pressure sensor 140.
- step S326 average pressure values of the pressures measured at unit time intervals are calculated, and in step S280, deviations from the average pressure values are calculated.
- step S330 It is determined whether the deviation calculated in step S330 is a value within a tolerance range. This is determined by comparing with the deviation set and stored in the controller 102. As a result of the determination, if the calculated deviation is a value within the tolerance range, the procedure proceeds to step S332 to display or inform the steady state or the check state through the display unit 104 and the alarm unit 108, and the calculated deviation is the tolerance. If the value is not within the range, the flow advances to step S334 to display and notify the endoscope 10 of the leak occurrence state through the display unit 104 and the alarm unit 108.
- the endoscope leakage inspection method according to the automatic mode takes about 30 to 40 seconds for pressurization, stabilization, inspection, and discrimination time, so that the state of the endoscope 10 can be quickly inspected.
- the endoscope 10 since only the leakage of the endoscope 10 is examined, the endoscope 10 is installed at the automatic endoscope leakage inspection apparatus 100 at any time before and after the procedure, so that the state of leakage can be quickly and easily identified. have.
