First, when the cleaning / disinfecting apparatus is used, the used endoscope 2 is set on the holding member of the cleaning tank 1, and perforation detection of the endoscope 2 is performed according to the flowchart shown in FIG. After that, as shown in FIG. 4, along with the operation of various operation switches (not shown), cleaning, disinfection, rinsing, air supply,
Each step of drying is performed.

一定時間経過後の圧力低下を圧力センサ３２によって測
定する。First, one end of the leak detection tube 30 is connected to the air supply port 9 of the endoscope 2 and the leak detection air supply pump 31 is operated to supply air to the inside of the endoscope 2. When the pressure inside the endoscope 2 reaches a certain level, the leak detection tube 30 and the leak detection air supply pump 31 are shut off from each other,
The pressure sensor 32 measures the pressure drop after a certain period of time.

At 1, the first pressure is supplied to the endoscope 2 and the pressure drop after a lapse of a certain time is measured by the pressure sensor 32. The first measurement is performed. Determine whether or not

る。If YES in step S2, the flow moves to step S3 to supply the endoscope 2 with a pressure higher than the first set pressure, and the pressure sensor 32 measures the pressure drop after a lapse of a certain time. Take the second measurement. That is, re-measurement is performed, and it is determined in step S4 whether the difference between the first and second measurement values is within a constant value B, and Y
In the case of ES, move to step S5, judge that it is a good product,
If NO, the process proceeds to step S6 and it is determined that the product is defective.

7, it is determined whether or not the pressure drop amount is smaller than the constant range A in the first measurement, and if YES, step S5
Then, it is determined that the product is non-defective, and if NO, step S6.
Move to and determine that the product is defective.

有無を決定する。As described above, the presence / absence of perforation of the endoscope 2 is determined according to the value of the pressure reduction amount, but the perforation of the endoscope 2 is extremely small (the case where the pressure reduction amount is within the range). In that case, a measurement error due to expansion of the endoscope 2 or the like may be the cause. Therefore, re-measurement is performed at a higher pressure, the measured values are compared, and the presence or absence of perforation is determined based on the size of the difference.

る。That is, the measurement error due to the expansion of the endoscope 2 does not change significantly even if the pressure value is increased, but the amount of pressure drop due to perforation increases as the pressure increases. It is possible to judge whether it is due to perforation or perforation.

２に噴射され、洗滌効果を発揮する。Next, the cleaning process is performed. First solenoid valve 14
When the valve is turned on and the valve is opened, the washing water stored in the water supply tank 13 is gravitationally fed through the water supply system pipeline 10 to the ultrasonic transducer 15
Flows into the through hole 35 of Here, the ultrasonic transducer 15
When oscillates, the cleaning water is atomized and sprayed on the endoscope 2 in the cleaning tank 1 to exert a cleaning effect.

（図示せず）を添加するとより効果的である。At the beginning of the washing step, the third switching valve 24 is on the drain side, and the washing water is sequentially drained, but after almost removing large dirt (preliminary washing), it is switched to the circulation side. The washing water is stored in the washing tank 1 and the endoscope 2 is immersed in the washing water. When the ultrasonic vibrator 15 oscillates in this state, ultrasonic waves are transmitted through the stored cleaning water, and the ultrasonic cleaning effect is exerted. It is more effective to add a detergent (not shown) to the stored cleaning water.

よび送気送水チャンネル内に送液される。Further, since the liquid feed pump 18 also operates at the same time, the cleaning water in the water supply tank 13 is first introduced to the channel connection ports 21 and 22 through the cleaning pipe line 12 in the scope pipe line, and the endoscope pipe. Endoscope 2 through the tube 23 for cleaning the road
Liquid is fed from the forceps port 7 and the air / water feeding mouthpiece 8 into the forceps channel and the air / water feeding channel.

動作を行なう。In this way, the cleaning water in the water supply tank 13 is initially sent into the air / water supply channel, but when switching to ultrasonic cleaning, the first switching valve 16 switches from approximately the same time to store water. To circulate. At this time, the second electromagnetic valve 22a is closed and the liquid feeding into the air / water feeding channel of the endoscope 2 is stopped. At the end of the washing process, the third switching valve 24 is again on the drain side, and the same operation as at the beginning of the process is performed.

By the operation of the disinfectant pump 27, the disinfectant solution in the disinfectant solution tank 26 is stored in the cleaning tank 1 via the disinfectant solution conduit 28. At the same time, the liquid supply pump 18 circulates and supplies the disinfectant solution into the forceps channel of the endoscope 2. The second solenoid valve 22a is open and liquid is also sent to the air / water supply channel. After a certain period of time, the third switching valve 24 is switched to the side of the disinfectant solution tank 26, and the disinfectant solution is spontaneously dropped and collected in the disinfectant solution tank 26. next,
The process proceeds to the rinsing process, but the disinfectant solution is rinsed by the same operation as at the beginning of the cleaning process (the third switching valve 24 is on the drain side).

By circulating the washing water through 5, the washing water is atomized by the ultrasonic vibration and jetted to the endoscope 2 in the washing tank 1, so that an excellent washing effect is exhibited, and the jet nozzle and the pump are provided. Since such a configuration is unnecessary, a compact and inexpensive device can be provided.

もとになることが考えらる。By the way, in ultrasonic cleaning, uneven cleaning occurs in the depth direction due to standing waves generated in the cleaning tank 1. That is, a portion having a high cleaning force and a portion having a low cleaning force are generated for each half of the wavelength λ. Therefore, the endoscope 2 is heavily soiled,
Moreover, when the part that easily collects is installed in this part where the cleaning power is weak, it is considered that stains remain and disinfection is not sufficiently performed, which may cause infection.
【００３４】図５〜図１１に示す内視鏡洗滌消毒装置
