Therefore, if compressed air is supplied while the entire endoscope is immersed in water in the cleaning tank 2, air bubbles leaking from holes in the outer skin of the endoscope will be removed. It is set so that it can be detected. Also, if compressed air is supplied when cleaning or disinfecting the endoscope, even if there is a hole in the outer skin of the endoscope, it will prevent the chemicals in the cleaning water from entering the inside through the hole. It's coming. Note that this leakage inspection is normally performed only on endoscopes whose entirety can be cleaned and sterilized.

On the other hand, as shown in FIG. 7, the first to third contact portions 4ya, 4yb, and 4yea of the first water level detection device 4G are connected to a CPU F g K as a control portion. And, even before starting the cleaning equipment, it's io! 1 point part 47
If m is on, it means that a sufficient amount of cleaning water is supplied from the water supply tank 4011C, and therefore, the switching valve 4 is closed by the signal from bCPUF-. When the cleaning equipment is started and the cleaning process begins, the water supply tank 4
0 water level decreases. Then, when the contact portion 41b of @2 is turned off, the first switching valve 44 is opened by the CPU r # in response to the signal, and cleaning water is supplied to the water supply tank 40. That is, the water level of the water supply tank 40 is controlled between the contact portion 4Fa of @1 and the contact portion 41b of IK2. In addition, when the IIE20 contact section 41k is off before starting the cleaning device, the cleaning water necessary for cleaning 111 is not stored in the water tank 4tjK in advance, so at that time, the cleaning device is activated by the signal from KtiCPUF#. It is now impossible to start it. Further, when the third contact portion 47c is turned off during the cleaning process, etc., there is no cleaning water in the cleaning water tank 40 f62, the first air tank 6M stops, and the second motor 6011C is turned off. The fifth switching valve G1 connects the cleaning 41 to the circular shape 11, and the first and second switching valve SO
, the third switching valve j2 and the fourth switching valve 5# are switched to the closed state 11. In other words, the cleaning equipment is stopped. In addition, the abnormality light 11 provided in the main/f channel section CK lights up, and the alarm (not shown) lights up! The date will sound to indicate this.

Further, the first to third contact portions jM*#1jabml8@ of the second water level detection device 51 are connected to the cptr y- which is the control section, as shown in FIG. There is. This first contact part j1& detects an abnormal rise in the water level in the chemical tank 42 (due to the inflow of cleaning water, etc.). When on, CPU F
K is set so that the disinfection process cannot be started by a signal from #. Also, in the middle of the cleaning process, the 4th motor 1-1 drain fil, and the 1st air 4th engine f6# stop, and the 304-ta gDIC
Therefore, the fifth switching valve 61 shuts off the cleaning tank 1 and makes it round 11, and the lI! 0 switching OFF switching The second switching valve is switched to the closed state 11. That is, the cleaning device is stopped. Furthermore, at this time, the abnormality run f21 provided in the main channel 9 channel section iK lights up and a de day (not shown in the figure) sounds to indicate this fact. In addition, the second contact portion i
It is normal when ab is on before transferring the chemical solution from the chemical tank 42 to the cleaning tank IK and starting the immersion sterilization process, but after starting the immersion sterilization process and after the circular plate, except during the recovery knee of the chemical solution. When it is turned on, K is in the cleaning tank 2 in the chemical tank 42.
This is because the chemical solution leaks from the tank and the water level rises.
The first contact portion 58a is turned on midway, and various devices are controlled in the same way as at 9:00, the cleaning device is stopped, the abnormal run f21 is lit, and a pud beep sounds. However, at this time, the drain 4 fill stops, and the fifth switching valve #I connects the cleaning tank 2 and the chemical tank 42 to a good state, that is, a state in which the disinfection process is interrupted and the chemical solution is recovered. In addition, the second
If the jab contact part is off from the beginning, it means that there is not enough chemical solution in the chemical solution tank 42 to immerse and disinfect the endoscope, so the disinfection process is started by a signal from CPU 7 #. I can't do it. Furthermore, the third contact portion Sat is connected to the chemical solution tank 4 during the disinfection process.
When the water level in the cleaning tank 2 is above a predetermined level and the switch is turned on, that is, when the chemical solution leaks from the cleaning tank 2 into the chemical tank 42 after a predetermined amount of chemical solution has been supplied to the cleaning tank 2 and the switch is turned off once. 1 Various devices are controlled by signals from CPU F 6 in the same way as when the first contact part jl1m is turned on midway,
The operation of the cleaning device is stopped.

Further, as shown in FIG. 9, the contact section 121 of the third water level detection device 110@1 and the second contact section fllk#'i are connected to the CPU F#K which is a control section.

The tenth contact point Fja detects that the water level in the cleaning tank 2 has risen too high. When this first contact point rja is turned on during the disinfection process, the second motor 60 activates the fifth contact point Fja. The switching valve 1 is switched to the state 11 which communicates the cleaning tank 2 and the drain tank 2, and the drain pump c1 is operated to discharge the liquid in the cleaning tank 2. Also, at this time, among the other equipment, IIEI's liquid fi1 stopped, and the fourth
The switching valve ip is closed. Furthermore, @2t) contact part rz
b is for detecting the appropriate water level in the cleaning tank 1. When the disinfection process neutralization is turned on, the chemical solution is supplied to the cleaning tank 2 at the appropriate water level. 1's fix stops. During the disinfection process, when a predetermined amount of chemical solution is supplied to the cleaning tank 2, turned on, and then turned off later, the chemical solution may have leaked from the cleaning tank 2 to the chemical tank 42 or to the drain tank 21Im. Therefore, this IK is designed to control various devices and stop the cleaning device in the same way as when the first contact portion 51a of the second water level detection device 51 is turned on during the disinfection process. , 1. Next, the endoscope is cleaned/liS using the cleaning device described above.
Explain the process of poisoning. First, the endoscope Jjie is installed in the cleaning tank 2. If the endoscope can be completely cleaned and disinfected, the entire endoscope is installed in the cleaning tank 2 as shown in FIG. The second air ring r1 is connected to the connecting lower 5& provided with the leakage test connector yHc by means of the first and second air rings F4m. When such preparations are completed, the power switch 31 of the bottle TTF plaster panel 1 with the cover 1 open is turned on to make it ready for operation. Tsuki ni, main no! Immediately when the leak test switch 1j of the panel si is pressed, the display run f20 of the main panel section 6 lights up, indicating that a leak test is in progress. This display will remain lit until all leak tests are completed. At the same time, the second
The motor 60 operates to close the fifth switching valve-1 and shut off the cleaning tank 2. Note that this fifth switching valve 61
The switching operation of the switch is properly regulated by the built-in switches. Immediately after the outflow of the cleaning tank 2 is completely blocked in this way, the second air 1yfrl starts operating and supplies compressed air to the internal space of the endoscope. On the other hand, when a certain period of time TI has passed after the 20th air index 11 is activated, IIN! When the switching valve J0 is opened, the sixth switching valve #1 communicates with the cleaning tank jllK.
K is switched, and the first liquid bonder jl is activated.

After that, the cleaning water in the water supply tank 40 is provided in the cleaning tank 2 and the third detection unit Fjb of the water level detection device r1 for the pills 3 is applied.
is supplied in a trench that is turned on. When water is poured into the cleaning tank 2, the entire endoscope installed in the cleaning tank 2 is submerged in water. Since the inside of this endoscope is pressurized with compressed air as described above, if there is a leakage point such as a crack or pinhole in the outer skin of the endoscope, air bubbles will come out from there. Therefore, it is possible to discover the leakage point by observing and introducing the leakage point.

If the leak test switch 15 is pressed again within a predetermined time, the operation time will be extended; however, if the switch is not pressed, the motor #O in the rear part 2 will automatically operate after the predetermined time has elapsed, and the fifth switching valve -1 is switched to the discharge side, and after the switching is completed, the drain pump 62 is operated to discharge the water in the cleaning tank 2. Although the second air tank 13 is also stopped, the pressurized state of the internal space of the endoscope remains unchanged. Then, when all the water in the cleaning tank 2 has been drained, the end jib will notify you of this fact.

At this point, the operations of the cleaning process using cleaning water and the disinfection process using chemical solutions will be explained. When only the cleaning process is selected, only that cleaning process is performed, but when the disinfection process is selected,
A cleaning step is performed as a pre-process. Therefore, the case where the disinfection process is selected will be explained. First, after setting the flush time setting timer j2 and the disinfection time setting timer JJ to predetermined times, turn on the start switch 14.
The display run fil will light up and the remaining time for the entire process will be displayed on the time display JFK. In addition, the second motor 60
operates to switch the fifth switching valve C1 to the discharge side. Immediately after this, the second liquid tank j1 is activated, and the first
The motor 5# operates to rotate the rotary nozzle 5j.

At the same time, the 70th switching valve 6# is switched to close and the first air 4-ring 61 is activated. Therefore, various channels rOK of the endoscope are connected to the water supply tank 4 by the 80th liquid dyfsaK.
The cleaning water sent from No. 0 and the compressed air sent from Ill's air pump #1 are mixed in the mixing header 65 and sent in good condition.

That is, since the so-called bubble flow of the channel y*5cri air tz phase is sent, the channel MO can be effectively cleaned1.In addition, the cleaning water in the water supply tank 40 is sent to the rotary nozzle 55 and the air pump 68 of the sll. The cleaning water is also sent to the nozzle 551 and sprayed onto the surface of the endoscope in the cleaning tank 2.

- On the other hand, a detergent can also be added to the washing water in this washing step ii. When adding detergent, turn on the detergent switch 10 before turning on the start switch 14. Then, l! for a predetermined time according to the washing time set by the washing time setting timer 32! The switching valve 2 of No. 3 is opened, and the detergent in the washing detergent tank 41 is added to perform what is called detergent washing. For example, if the washing time setting timer 32 is set to a 3-minute scale, detergent will be added for the first minute at the start of washing, and if it is set to a 5-minute mark, detergent will only be added for 2 minutes after 1 minute has passed since the start of washing. Detergent is added. Furthermore, when the scale is set to 6 minutes, detergent is added for 3 minutes after 1 minute has passed after the start of washing. That is, when the detergent switch 10 is turned on, the time for adding detergent is automatically set according to the washing time set by the washing time setting timer IIK, and after washing with detergent, only washing water is always supplied and the detergent is added. A so-called rinsing process is performed for a certain period of time to remove.

When this rinsing process is completed, the second liquid 47g s4 is stopped, and the supply of cleaning water is stopped.

At the same time, the first motor 16 stops (t), and the rotating nozzle 6
I stops rotating. However, the first air
Fi continues to operate for a certain period of time and channel 1 of the endoscope
Only air is supplied into the chamber, and the remaining cleaning water is discharged therein. Note that the drain tank fig operates until the cleaning water in the cleaning tank 2 is completely exhausted, and then automatically stops.

The above is the cleaning process, and when only the cleaning process is selected, K ends here. However, since the disinfection switch is pressed and the disinfection kingship is selected, the disinfection process is performed following the cleaning process.

That is, the second motor O operates and the i-th switching valve 1
2 is switched to the blocking state 111. Immediately after this, the fourth switching valve 5# opens, and the liquid of pill 1? hmm! 5 is activated, the chemical solution in the chemical solution tank 42 is supplied to the cleaning tank 2.

And the endoscope is fully immersed in the chemical solution! When IK is reached, the second contact portion Fjb of the third water level detection device 11 turns on and detects this, and a high detection signal is input to CPUF#. This K causes the sixth switching valve 6J to switch,
Supply the drug solution to the 1° channel of the endoscope. and,
When the channel 10 is filled with the chemical liquid and the contact part 58 of 111E3 of the third water level detection device j1 is turned off, the fourth switching valve 59 is closed and the first liquid is filled with 4 ml.
stops. That is, not only the outer surface of the endoscope but also the inside of the channel 10 is immersed and sterilized in the chemical solution. .

The time for this immersion disinfection is the time selected by the disinfection time setting timer IJK in the N/F channel section IK. There are multiple types of time that can be selected; in this embodiment, 10 minutes, 20 minutes, and 30 minutes can be selected using the dial of the disinfection time setting timer J3. In addition, 1 is selected when the overnight switch 12 of the main/quantity channel section C is pressed.
You can select 0 hours. When cleaning and disinfecting the entire endoscope, K should be installed as shown in FIG. 3. The detection switch 19a should be installed as shown in FIG.

Since 1911 is not operated at the same time, a control means (not shown) is activated, and immersion disinfection can be performed during any of the above-mentioned times selected. However, if the endoscope is of the type where only the insertion section is installed in the cleaning tank 2 to be cleaned and disinfected, it should be installed as shown in Figure 2).
Detection switches J#a and J#b are both operated to determine the type of endoscope. Then, the control unit for the sterilization process is operated by the detection of lin, and if the sterilization time of 1 above 30 minutes and open (10 hours) is selected, 4, it does not operate. In the case of this type of endoscope (so-called conventional type), only IIK is activated when either 10 minutes or 20 minutes is selected.

Note that once the disinfection time is set using the disinfection time setting timer 31, the main channel 9 section 6
Just by pressing the disinfection switch 11, disinfection will be performed for that time. Therefore, if one of these times is selected in advance, there is no need to perform a selection operation each time, so the selection process is not cumbersome (and easy to use).

On the other hand, when the travel time set by the disinfection time setting timer SS< has elapsed, the chemical solution recovery operation is performed. That is, when the second motor #0 operates and the MAL is switched so that the inlet of the fifth switching valve-1 communicates with the chemical liquid tank 42, the chemical liquid in the cleaning tank 2 is returned to the chemical liquid tank 42. K, first air $7f6 Ji is activated and endoscope channel MO
The chemical solution that has entered the tank is also drained and collected.

When this collection is completed, the second motor #0 is operated again, the fifth switching valve c1 is switched to the discharge 11, and the drain cylinder is
starts operating. At the same time, the first air men fix and the second liquid pump f54 are operated to perform the same rinsing operation as described in 9 above, and water washing by bubble flow is performed without adding tb detergent. Not only the outer surface of the mirror but also the inside of channel 1# is rinsed. When this rinsing is finished, the liquid 47!14 stops,
Only the first airman, ypia, continues to operate to drain water in channel 1#.

Now, the above disinfectant! When the disinfection switch 11 is turned on and the switch 12 is turned on, the endoscope is immersed in the chemical solution for a long time. The process is then carried out. Overnight disinfection, such as Ni, has excellent chemical resistance and is used to reliably disinfect round endoscopes.

On the other hand, Napuno Mannel Iku JjK is set up for nine months.

water flush switch J (or air switch,
1 can be turned on, the water can be drained during washing as described above, and when replacing the chemical solution in the tank 4z, the first liquid 1! can be turned on by turning on the discharge switch IC. :/fil.

Drainage ponnoro 2, 4th. Fifth. Sixth switching valve 5#.

61 and 63 are activated and the chemical solution is discharged.

By the way, if you want to perform so-called detergent washing with a detergent during the cleaning process using the cleaning device configured as described above, all you have to do is turn on the detergent switch 10 before turning on the start switch 14, and then turn on the detergent switch 1#. According to K, the third switching valve 52 is opened for a predetermined time according to the washing time determined by the washing time setting tie-vllK, and the detergent in the detergent tank 41 is added to the washing water.

That is, when the washing time is set to 3 minutes as described above, the detergent is added to the barrel for the first minute at the same time as the washing starts, and the remaining 2 minutes are washed only with washing water. Similarly, when the set time is 5 minutes, detergent is added for 2 minutes after 1 minute has passed from the start of washing, and the remaining 2 minutes are washed with 1 K of washing water, and the set time is 6 minutes further. When , detergent is added for 2 minutes after 1 minute has elapsed from the start of cleaning, and the remaining 2 minutes are cleaned with only cleaning water.

That is, since the detergent addition time is automatically set to a predetermined time by setting the washing time, it is inevitable that the detergent may be forgotten or the detergent washing time may be inconsistent depending on the operator. In addition, since detergent is added to the washing water and then washing is carried out using only the washing water, the detergent can be reliably washed away from the endoscope. It is only necessary to store the detergent stock solution in the detergent tank 41, so that the capacity of the detergent tank 41 can be reduced.

As explained above, in this invention, any zero time length that matches the type of endoscope is selected and disinfection can be performed during that time, so there is no need to select a disinfection time each time, and the rounding easy to use. Furthermore, when a disinfection time that is not compatible with the endoscope is selected, the disinfection process is not performed, thereby preventing the endoscope from being damaged by the chemical solution and ensuring safety.
