The main body 2 is provided with a tap water supply inlet 4, a chemical solution supply pipe 6 for supplying disinfectant from a chemical solution tank 5, a discharge pipe 7, and the like. The endoscope installed in the cleaning tank 3 is cleaned and rinsed using tap water supplied through the supply receiving port 4. Note that this used water is disposed of through the discharge pipe 7. In addition, the disinfectant solution from the chemical tank 5 is supplied to the cleaning tank 3 through the chemical solution supply pipe line 6, and the endoscope is immersed in this chemical solution. It is now possible to disinfect endoscopes with a chemical solution.

Furthermore, the endoscope cleaning device 1 is provided with an ozone receiving means 12 to which an ozone supply means 11 on the side of an ozone generator (means) 10, which will be described later, is connected.

The ozone supply means 11 and the ozone reception means 12 are
It is configured as shown in the figure. That is, a connecting socket 13 is provided at the end of the pipeline of the ozone supply means 11, and this connecting socket 13 is connected to the ozone receiving means 12.
It can be inserted into the receiving cap 14 of. Further, the receiving cap 14 is provided with a locking ball 15 that protrudes and retracts from the inner surface of the receiving cap 14, and the locking ball 15 can be protruded by advancing an operating ring 16 that is attached to the outer periphery of the receiving cap 14 so as to be freely retractable. The inner surface portion 17 projects from the inner surface of the receiving cap 14 . Furthermore, when the operating ring 16 is moved backward, its protruding inner surface 17 comes off from the locking ball 15, preventing the locking ball 15 from protruding. The operating ring 16 is urged in the forward direction by a coil spring 18. The final forward position of the operating ring 16 is regulated by a stopper 19. Then, when the operating ring 16 is moved forward and the locking ball 15 is pushed out,
The insertion cap 13 inserted into the receiving cap 14 is fitted into and locked into a circumferential locking groove 20 formed on the outer periphery of the insertion cap 13.

Further, connection rings 23 and 24 are provided on the inner surface of the receiving cap 14 and the outer surface of the insertion cap 13, respectively, for connecting the signal transmission system 21 on the endoscope cleaning device 1 side and the signal transmission system 22 on the ozone generator 10 side. is provided. When the insertion cap 13 is inserted into the receiving cap 14, ON and OFF signals from the ozone generator 10 are transmitted through the respective signal transmission systems 21 and 22.

Further, on the inner surface of the receiving cap 14, a detecting means 9 made of, for example, a touch sensor is provided, which detects when the connecting socket cap 13 is inserted therein.

The signal transmission system 25 of the detection means d and the signal transmission system 21 are connected to a control means 26 for controlling the operation of the endoscope cleaning device 1.

This control means 26 has a memory (not shown), and operates according to procedures stored in this memory.

Further, an operation switch 27 is attached to the endoscope cleaning device 1 side.

Further, as shown in FIG. 1, the ozone generator 10 is provided with an ozone generator 29 within its main body 28, and an oxygen cylinder 30 and a tap water supply pipe 31 are connected to the ozone generator 29. This ozone generator 29 is configured to add ozone to tap water to form ozonated water. As the ozone generating means of this ozone generator 29, various methods such as a silent discharge method, an electrolysis method, a photoreaction method, a high frequency electrolysis method, etc. can be used, and here, for example, a so-called solid polymer electrolysis method is used. This is a method in which electrodes are placed on both sides of a solid polymer electrolyte membrane (for example, a fluorine-based cation exchange membrane), and pure water is supplied to the anode side. According to this method, since ozone is generated by electrolysis from pure ozone, cleaner ozone can be obtained compared to the general discharge method. Note that this ozone generator 10 is provided with an activation switch 32.

Next, the operation when using the endoscope cleaning device 1 configured as described above will be explained. When this endoscope cleaning device 1 is used in the same manner as the previous one (sterilization method A), it is used as is without connecting the ozone generator 10 to it. That is, in this case, the connecting socket 13 of the ozone supply means 11 in the ozone generator 10 is not inserted into the receiving mouth 14 of the ozone receiving means 12.

For this reason, the detecting means 9 consisting of, for example, a touch sensor detects that the endoscope cleaning device 1 is disconnected.
The control means 26 instructs the operation to take place in accordance with the conventional disinfection method. That is, the endoscope cleaning device 1 performs the following procedure on the endoscope housed in the cleaning tank 3: "cleaning" = "chemical disinfection" - "rinsing" = "drying".

"Cleaning" is performed in step 1j (Use the tap water poured into the supply/reception port 4, mix detergent with it to make cleaning water, and inject this into the outer surface of the endoscope and into the channel. The cleaning water after use is discharged through the discharge pipe 7. In "chemical disinfection", the disinfectant solution from the chemical tank 5 is supplied to the cleaning tank 3 through the chemical supply pipe 6, and the endoscope after cleaning is poured into this chemical solution. This is done by immersing the mirror and supplying a chemical solution directly into the channel of the endoscope.This chemical solution is usually collected and reused without being discarded.Also, ``rinsing''
This is done by injecting detergent-free tap water into the outer surface and channels of the endoscope. This used tap water is disposed of through the discharge pipe 7. "Drying" involves blowing air into the channels of the rinsed endoscope to drain water and dry it.

On the other hand, when using the endoscope cleaning device 1 with the ozone generator 10 connected (disinfection method B), the ozone supply means 11
The connection insertion cap 13 is inserted into the receiving cap 14 of the ozone receiving means 12 on the cleaning device 1 side for connection. As a result, the detection means 9 detects the connected state and notifies the control means 26 of the connected state.

Therefore, the ozone generator 10 is activated.

32 and at the same time, when the operating switch 27 of the endoscope cleaning device 1 is turned on, it is first determined whether or not the ozone generator 10 is operating. ON/OFF information of the ozone generator 10 is received through the signal transmission system 22 and the signal transmission system 21 on the endoscope cleaning device 1 side. In this case, if the ozone generator 10 is not operating, an abnormality is displayed. When the ozone generator 10 is operating, a process using ozonated water is selected.

That is, the endoscope, which has received ozone water through the ozone supply means 11 and the ozone reception means 12 and is stored in the cleaning tank 3, is cleaned with ozone water. As a result, the endoscope is cleaned and disinfected at the same time.The air or ozonated water to be discarded from the cleaning tank 3 is treated to remove ozone by an ozone removal means (not shown) before being disposed of. "Drying" may also be performed. Further, after the cleaning treatment with tap water, (cleaning) disinfection with ozone water may be performed.

4 and 5 show a second embodiment of the present invention. In this second embodiment, the operation switch 27 in the endoscope cleaning device 1 in the first embodiment is used to command the ON operation of the ozone generator 10. This signal is transmitted through the signal transmission system 22 on the connected ozone generator 10 side and the signal transmission system 21 on the endoscope cleaning device 1 side. Other configurations etc. are listed in 1 above.
This is similar to that of the embodiment. FIG. 5 shows the flowchart.

According to this embodiment, there is no need to provide the activation switch 32 on the ozone generator 10 side, and the ozone generator 10 can be activated by operation on the endoscope cleaning device 1 side. In addition, an ozone generator 1 is added to the endoscope cleaning device 1.
If 0 is not connected, the ozone generator 10
Since the system does not operate, there is no risk of spreading ozone into the surrounding area, improving safety.

FIG. 6 shows a third embodiment of the invention. In this third embodiment, the chemical supply pipe 6 in the cleaning device 1 and the pipe in the ozone receiving means 12 are used together, and one of them is selected and used using an electromagnetic switching valve 35. be. The switching valve 35 is configured so that the detecting means 9 provided in the receiving cap 14 of the ozone receiving device 12 is connected to the ozone generator 10 in the receiving cap 14.
When it is detected that the connection socket 13 of the ozone supply means 11 is connected, the ozone reception means 12 is connected to the cleaning tank 3 side, and when the connection between the ozone supply means 11 and the ozone reception means 12 is not detected, the chemical solution is supplied. Connect the pipe line 6 side to the cleaning tank 3 side. Then, a corresponding operation is performed depending on each state. In other words, ozone generator 1
When 0 is connected, cleaning etc. are performed using the ozone water. Further, when the ozone generator 10 is not connected, conventional general cleaning, chemical disinfection, rinsing, drying, etc. are performed using only the cleaning device 1 side.

Note that the present invention is not limited to the above embodiments. For example, instead of being supplied as ozone water from an ozone generator, it is also possible to receive ozone gas and use it for disinfection and the like.

[Effects of the Invention] As explained above, according to the present invention, a conventional type of endoscope disinfection device can be utilized by simply adding a simple means, and since ozone is used, endoscopes can be disinfected in a short time. Can be disinfected efficiently.
