た。2. Description of the Related Art Generally, an endoscope is cleaned and disinfected after use. Recent endoscopes are used to clean and disinfect the entire endoscope.
The entire endoscope has a waterproof structure. By the way, the flexible tube of the insertion portion and the outer skin of the bending tube are portions that can be moved violently, and damage is likely to proceed. In addition, since the channel tube and the like inserted into the endoscope are made of rubber, they are relatively weak waterproof parts.
Moreover, there is a possibility that the needle may be accidentally punctured by an endoscopic injection needle or forceps during the inspection, and the needle may be damaged.

れを防ぐ必要がある。If the endoscope is used as it is in such a state, water will enter the inside of the endoscope main body, causing a failure and incurring a great repair cost. For this reason, it is necessary to detect holes, cracks, and the like formed in the outer skin of the endoscope, for example, the outer skin of the curved portion, the channel tube, and the like at an early stage to prevent a large amount of water leakage.

を行う減圧量測定式漏水検知が知られている。Leakage detection in a conventional endoscope cleaning / disinfecting apparatus is performed during a cleaning process or as an independent process. One method is to inject gas into an endoscope set in a cleaning tank. There is known a decompression amount measurement type water leakage detection in which water leakage is detected by pressurizing and measuring a decompression amount from a pressurization set value.

A bubble detection type leak detection method is known in which the endoscope is submerged there, and gas is injected into the endoscope to pressurize and visually detect bubbles leaking from the inside of the endoscope to detect water leakage. Has been. Then, in the conventional endoscope cleaning / disinfecting apparatus, any one of the methods has been selected to detect water leakage.

れやすいものであった。By the way, the detection accuracy of the former decompression amount measurement type water leakage detection method depends on the pressure measuring means (pressure sensor or the like). However, the accuracy is greatly affected by external factors (temperature of cleaning tank, temperature of cleaning liquid, etc.). Therefore, it is possible to detect water leakage with a new endoscope or an endoscope with a large hole relatively accurately, but in a detection situation that requires fine accuracy such as when a small hole is opened. It was easily affected by the condition of the cleaning tank.

た。On the other hand, in the latter bubble detection type water leakage detection method, water leakage can be accurately detected regardless of the size of the hole. However, each time the bubble detection type water leak detection is performed, the user has to directly visually observe, and there is a restriction that the user cannot leave the device during the water leak detection.

The present invention has been made in view of the above-mentioned problems, and an object thereof is an endoscope capable of surely performing leak detection regardless of the size of a leak hole and efficiently performing leak detection. It is to provide a cleaning and disinfecting device.

を行うことができる。In the water leak detection by the endoscope cleaning / disinfecting apparatus, first, the water leak detection of the reduced pressure amount measurement type is performed. When the amount of pressure reduction from the set pressure exceeds the criterion value, a warning is issued to the user and a bubble detection type leak detection is performed. This is a method of detecting water leakage by storing water in a cleaning tank while the endoscope is being pressurized, and bubbles are generated when the endoscope has minute holes. Therefore, by confirming the generation of bubbles, reliable water leak detection can be performed. In addition, the user does not have to be always near the device every time water leak is detected, and it is sufficient to be near the device only when an abnormality is suspected and when bubble detection water leak detection is performed, so work efficiently.

Press to start the operation of the cleaning process. On the other hand, FIG.
In the flow performed in the independent process shown in (a), when A or less (A ≧ x), the endoscope 2 ends as normal, and when the decompression amount x exceeds a predetermined value B (B For ≦ x), it is processed as a scope abnormality. Further, when the reduced pressure amount x is within the range of a predetermined value (A <x <B), the warning means 11 starts to warn of the abnormality of the endoscope 2, but the process is not temporarily stopped.
