In addition, if compressed air is supplied when cleaning or disinfecting the endoscope, even if there is a hole in the outer skin of the endoscope, cleaning water or chemicals can be prevented from entering the inside through the hole. can.

On the other hand, the contact portions 47m, 4rb, and 4' IC of the water level detection device 46 of @1 through the sliding door 3 are connected to the CPU 7g as a control portion, as shown in FIG. If the contact part 41 of @l is turned on from the time when the cleaning device is started, it means that enough cleaning water is supplied to the water tank 40, so the @1 The switching valve 44 is closed.

Start the cleaning equipment and begin the cleaning process.

The water level in the water tank 40 decreases. Then, when the contact part 47b of II2 is turned off, the CPU
The 1ml switching valve 44 is opened by i, and the water supply tank 40 is opened.
Washing water is supplied to the

That is, the water level of the water supply dunk 40 is at the first contact point 47m.
and the second contact portion 41b. In addition, if the contact part 47b of @2 is off before starting the cleaning device lIv, it means that the cleaning water necessary for the cleaning process is not stored in the water supply tank 4o in advance, so at that time, the cleaning simv is started by a signal from the CPU 76. It is now impossible to do so. Furthermore, 56,
Drainage bond gz, first air bond 68 stopped +hL,
1N! The motor 60 of @2 causes the switching valve 61 of @5 to shut off the cleaning tank 2, and the switching valve 5 of @2
0. ! The thirteenth switching valve 52 and the fourth switching valve 59 are switched to the closed state.

In other words, the washing device is stopped. Further, at this time, an abnormality lamp 28 provided on the main panel section 6 lights up and a buzzer (not shown) sounds to indicate the fact.

Further, the first and third contact portions 58m, 18b, and 58c of the $2 water level detection WtWltiy are connected to the CPUFg, which is a control portion, as shown in FIG. This first contact part 581 detects an abnormal rise in the water level in the chemical tank 42 (due to inflow of cleaning water, etc.), and this @1 contact part 58 is turned on before the cleaning device is activated. At this time, the disinfection process cannot be started by a signal from cPtry'g. In addition, during the cleaning process, the air bonder 68 of ZORRO 131 is stopped, and the motor 60 of II2 causes the fifth switching valve 61 to shut off the cleaning tank 2.
The switching valve 52 of #12 and the switching valve 5# of @4 are switched to the closed state. That is, the cleaning device is stopped.

Further, at this time, the abnormality land 28 provided at the sixth main f-channel lights up, and a buzzer (not shown) sounds to indicate this fact. Also.

2nd contact part sttb-b When it is turned on except during a process, the chemical liquid leaks from the cleaning tank 2 into the chemical liquid tank 41 and the water level rises. is controlled, the cleaning device stops, the abnormality lamp 28 lights up, and the buzzer sounds. However, at this time, the drain ON f62 is stopped and the fifth switching valve 61 is placed in a state where the cleaning tank 2 and the chemical solution tank 42 are communicated with each other, that is, the disinfection process is interrupted and the chemical solution is recovered. Also, if the contact part 5#b of #42 is off from the beginning, it means that there is not enough chemical solution in the medicine tank 42 to sterilize the endoscope by immersing it in the medicine tank 42.
The disinfection process cannot be started by the signal from PU7g.

Furthermore, the third contact part SaC is turned on when the water level of the chemical solution tank 42 is above a predetermined level during the disinfection process, that is, after a predetermined amount of the chemical solution is supplied to the cleaning tank 2 and turned off once. When the chemical solution leaks from the cleaning tank 2 into the chemical solution tank 42, it! In the same way as when the contact section 681 of No. 1 is turned on midway, various devices are controlled by signals from the CPU 76,
The operation of cleaning 1iit is stopped.

Further, the II contact section 721 and the second contact section vxb of the third water level detection device 11 are connected to the control section cpuyg as shown in FIG. The first contact part 7JJl is for detecting that the water level in the cleaning tank 2 has risen abnormally. When the contact part 121 of @1 is turned on during the disinfection process, the second motor 60 ! 5 switching valve 6
1 switches to a state in which the cleaning tank 2 and the drain tank 62 are in communication with each other, and the drain tank 62 operates to discharge the liquid in the cleaning tank 2. Moreover, at this time, among other devices, the first liquid pump 61 is stopped and the fourth switching valve 59 is closed. moreover.

The contact part 72b of @2 detects the appropriate water level of the cleaning tank 2, and when it is turned on during the disinfection process, it means that the g liquid has been supplied to the cleaning 4112 at the appropriate water level, so the fourth switching valve 6
9 is closed and @1's one hand 51 is stopped. In addition, when a predetermined amount of chemical solution is supplied to the cleaning tank 2 during the disinfection process and it is turned on and then turned off, the chemical solution leaks from the cleaning tank 2 to the #A liquid tank 42 or the drain pump 62 side. Therefore, at this time, various devices are controlled and the cleaning device is stopped in the same way as when the first contact part 58- of the water level detection device @sr of the sliding door 2 is turned on in the middle of the disinfection process. ing.

Next, a process of cleaning and disinfecting an endoscope using the L-era cleaning device will be described. First, the endoscope is installed in the washing tank PP'a2, but if the entire endoscope can be cleaned and disinfected, the entire endoscope is installed in the washing tank 2.Then, the endoscope's various channels are 70 and the supply port 5 are connected with a tube (not shown).In addition, a connector 15 for leakage inspection of the endoscope is connected.
The air bonder 13 of @2 is connected to the connection port provided at 2 with a tube (not shown). After completing these preparations, turn on the power switch 31 of the sub-panel section 8 with the cover 3v open.

Make it operational. Next, when the leakage measurement switch 15 on the main panel section 6 is pressed, the main panel section 6
The indicator lamp 20 lights up to indicate that leakage measurement is in progress. This display will remain lit until all leakage measurements are completed. At the same time, the second motor 60 operates and the fifth
The switching valve 61'Ik is closed and the cleaning tank 2 is shut off. Incidentally, the switching operation of the switching valve 61 of this switch 5 is correctly regulated by a limit switch incorporated therein. Immediately after the outflow of the cleaning @X is completely blocked in this way, the air bonder 23 of the funeral 2 starts operating and supplies compressed air to the internal space of the endoscope. On the other hand, after the air bonder 73 of @2 is activated, a certain period of time T has elapsed.

The +1142 switching valve 50 is opened, the sixth switching valve 63 is switched to the state where it communicates with the cleaning tank 2 side, and the first liquid bonder 51 is activated.

Therefore, the cleaning water in the water supply tank 40 reaches the second detection unit 72 of the @3 water level detection device 17J provided in the cleaning tank 2.
It is supplied until b is turned on.

In this way, when water is poured into the washing tank #-' tank 2, the entire endoscope installed in the washing tank 2 is submerged in water. So[,
As mentioned above, the inside of this endoscope is pressurized with compressed air, so 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 the endoscope. Therefore, by inspecting and confirming this, the location of the leak can be discovered.

In addition, if the leak test switch 15 is pressed again within a predetermined time, the operation time will be extended, but if the leak test switch 15 is not pressed again, the motor 60 of @2 will be automatically activated after the predetermined time has elapsed.
The switching valve 611 is switched to the discharge side, and after this switching is completed, the C2 pump 2 is operated to discharge the water in the washing tank 2. Although the 12 air bonders 13 also stop, the pressurized state of the internal space of the endoscope continues for a while. When all of the water in the cleaning tank 2 has been drained, an end buzzer sounds to notify you of this.

Next, the operations of the cleaning process using cleaning water and the disinfection process using chemical solution 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 step vli1 is selected will be explained. First, after setting the washing time setting timer 32 and the disinfection time setting timer 33 to a predetermined time, when the start switch 141 is turned on, the display 19 lights up and the remaining time of the entire process is displayed on the time display 11. be done. In addition, the second motor 60 operates to switch the switching valve 6Jv @5 to the discharge side. Immediately thereafter, the second liquid cylinder 51 is activated and the motor 5C of @l is activated to rotate the rotary nozzle 55. At the same time, the switching valve 69 of II7 is switched to close, and the air bonder 68 of Ill is activated.

Therefore, the cleaning water sent from the water supply tank 40 by the @2 liquid bonder 54 and the compressed air sent from the first air bonder 68 are mixed in the mixing header 65 and sent to the various channels 70 of the endoscope. It will be done. That is, since a so-called air flow is fed into the channel 70, the channel 70 can be effectively cleaned. Also, the cleaning water in the water tank 40 is supplied by the first air pump! The cleaning water is also sent to the rotating nozzle 55 by the cleaning tank 2 and sprayed onto the surface of the endoscope within the cleaning tank 2.

Before turning on the start switch F14V, turn on the detergent
Put it in Of. Then, the switching valve 52 of IS3 is opened for a predetermined time according to the washing time set by the washing time setting timer 32, and the detergent in the detergent tank 41 is added to the washing water, so that so-called detergent washing is performed. for example,
When the washing time setting timer 32v is set to 3 minutes, detergent is added for the first minute at the same time as washing starts, and when it is 5 minutes, detergent is added for only 2 minutes one minute after the start of washing. Furthermore, at the time of 6 minutes, the detergent is added for 3 minutes after 1 minute has passed from 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 32, 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 liquid 54 of @2 is stopped, and the supply of washing water is stopped.

At the same time, the motor 56 of @1 stops, and the rotating nozzle 6
5 stops rotating. However, @1's air bond 68
continues to operate for a certain period of time to supply only air into the channel 10 of the endoscope and discharge the cleaning water remaining therein. Incidentally, the drain bond 62 is operated 15 until the washing water in the washing water 2 is completely exhausted, and then automatically stopped.

If only the cleaning process is selected, the process ends here. However, when the disinfection switch 11f2- is pressed to select the disinfection process, the disinfection process is performed following the cleaning process.

That is, the motor 60 of @2 operates and the fifth switching valve 6
1 switches to the cut-off state. Immediately after this, the fourth switching valve 59
opens and the *1 liquid 4 inverter 51 is activated, thereby supplying the chemical liquid in the chemical liquid tank 42 to the cleaning tank 2. When the endoscope is fully immersed in the chemical solution, #! 3
The contact part rzb of @2 of the water level detection device 7 turns on and detects this, and this detection signal is c: p U 7 g
is input. As a result, the switching valve 63 of @6 is switched, and the chemical solution is supplied to the channel 70 of the endoscope. Then, when the channel 70 is filled with the chemical liquid and the third contact portion Sac of the third water level detection wswsy is turned off, the fourth switching valve 59 is closed, and the first liquid bonder 51 is closed.
stops. That is, not only the outer surface of the endoscope but also the inside of the channel 70 is immersed and sterilized in the chemical solution.

Then, when the time set by the disinfection time setting timer 33 has elapsed, the iMP& is collected. That is, the second motor 60 is operated and the inlet of the switching valve 6 of @5 is switched to the state where it communicates with the S liquid tank 42).
While returning the medicine P&O in the cleaning tank 2 to the chemical liquid tank 42,
The air end 68 of I@1 is operated to discharge and collect the medicinal liquid that has entered the channel 70 of the endoscope.

When this collection is completed, the motor 60 of writing I'$2 is operated, the switching valve 61 of @5 is switched to the discharge side I), and the drain bond 62 starts operating. At the same time, the first air bonder 68 and the liquid bonder 54 of I12 are activated, and the same rinsing operation as described above is performed, that is, rinsing with air and 8i flow is performed without adding detergent. The inside of the channel 10 as well as the outer surface of the container 10 is rinsed. After this rinsing process is completed, @2 liquid on 7'54
stops +ht, only the air pump 68 of porridge 1 continues production 11 [2 and drains the water in the channel 70].

In addition, in the disinfection process described in F, the disinfection switch 11 is replaced (1).
When the overnight switch 12 is turned on, the endoscope is
After being immersed in the liquid for a long time, for example for 10 hours, the above-mentioned rinsing step and draining step are performed. Such overnight disinfection is used to reliably disinfect endoscopes with excellent chemical resistance.

-) By turning on the manual flushing switch 34 or air switch 35 provided in the J, sub-9 channel section 35, the above-mentioned flushing and draining can be performed, and when replacing the chemical solution in the chemical solution tank 42. If you turn on the discharge switch 362, Jll! 1 liquid pump 5, drainage bond 62, fourth, fifth, and sixth switching valves 59, 61. ．． 63 is activated and the chemical solution is discharged.

By the way, according to the cleaning device having the above configuration, the water supply tank 4
A water level detection device @4te of $1 is provided at 0, and when the contact part 4rb of fs2 is off before the start of the cleaning process, the cleaning device will not operate even if the start switch 14v is pressed. In other words, the cleaning process is not started unless a predetermined amount or more of cleaning water is stored in the water supply tank 4o in advance. Therefore, even if a large-capacity liquid bonder 64 is used in @2 to supply as much cleaning water as possible to the cleaning tank 2 per unit time, the cleaning water in the water supply tank 40 will be exhausted within a predetermined cleaning time. There is no chance that the endoscope will not be able to be cleaned reliably due to running out.

As described above, this invention prevents the water tank from moving. In other words, if the water supply tank does not have a predetermined amount of cleaning water stored in advance, the cleaning device will not start and the cleaning process will start, so the cleaning water in the water tank runs out during the cleaning process There is no possibility that the endoscope cannot be properly cleaned.
