As shown in Japanese Patent Application Laid-Open No. 59-32435, a conventional endoscope cleaning device temporarily stores water supplied from a water tap in a water storage tank, and then sends this water to each channel of the endoscope using a water pump. It's becoming like that. In this way, the water supplied from the tap is temporarily stored in the water storage tank because the strength of the endoscope channel is generally lower than the water pressure flowing out from the tap.
This is because the channel tube will burst if it is sent directly into the channel. Therefore, a water pump is used to pump out water at a constant water pressure within the tolerance range of the channel of the endoscope.

The cleaning conduit 9 consists of a main cleaning conduit section 10 and an outer surface cleaning conduit section 11 and an inner channel cleaning conduit section 12 that branch from this, and the outer surface cleaning conduit section 11 is connected to the cleaning tank 3. It opens toward the outer surface of the endoscope 4 installed inside, and tap water is sprayed onto the outer surface of the endoscope 4. Further, the channel cleaning conduit section 12 is further branched into two parts, each of which has a connecting part 13, 13 at its tip. These connecting parts 13, 13 are connected to the cylinders 6, 6 from which the piston of the endoscope 4 is removed.
It is designed to connect to each.

定されている。 Further, a pressure reducing valve 14 is inserted at the base of the channel cleaning pipe section 12. This pressure reducing valve 14 is constructed as shown in FIG. That is, this pressure reducing valve 14 incorporates a valve body 16 biased by a spring 15, and this valve body 16 opens the passage 18 to some extent at a position where the water pressure on the outlet 17 side and the biasing force of the spring 15 are balanced. In this state, water flows from the inlet 19 to the outlet 17 side. When the water pressure on the outlet 17 side becomes higher than this, the spring 15 is inserted and the valve body 16 moves in the direction of closing the passage 18 to restrict or cut off the water supply. In other words, the pressure reducing valve 14 is designed to lower the pressure to a predetermined level and then send it out. This predetermined pressure is set within the tolerance range of the channel 5 of the endoscope 4.

される。 When the endoscope 4 is cleaned using the cleaning device 2, the procedure is as follows. first,
The endoscope 4 with the piston removed from the cylinders 6, 6 of the pipe switching valve is installed in the cleaning tank 3, and
Each connection part 13, 1 of the channel cleaning pipe line 12
3 is connected to the cylinders 6 and 6 above. Further, when the hose 8 is connected to the water faucet 7 and the water faucet 7 is opened, tap water is fed through the hose 8 and the main washing pipe section 10. Then, a portion of the tap water is relatively strongly jetted out from the outer surface cleaning conduit section 11 toward the outer surface of the endoscope 4 to clean the outer surface. Further, other tap water is sent to the channel cleaning pipe section 12, but first the pressure is reduced by the pressure reducing valve 14 to a pressure within the tolerance range of the channels 5 of the endoscope 4. The reduced pressure water is sent into each channel 5 to clean the inside of each channel 5, and flows out from the other end of each channel 5 into the cleaning tank 3. Further, water falling into the cleaning tank 3 is discharged from the drain port 20.

る。 FIG. 5 shows a fourth embodiment of the invention. In this embodiment, a pipe switching section 22 is inserted in the channel cleaning pipe section 12 of the first embodiment at a portion upstream of the pressure reducing valve 14. Then, the water removal air pipe 23 is connected via this pipe switching section 22.
Connect. Furthermore, this air conduit 23 for water removal is connected to an air supply pump 24, and a warmer 25 is inserted in the air conduit 23 for water removal.

い。 Therefore, in this embodiment, by switching the pipe line switching section 22 after cleaning the channel 5 of the endoscope 4, the air sent from the air pump 24 can be sent into the channel 5 and water can be drained. Further, since this air is heated by the heater 25, the inside of the channel 5 can be quickly dried. Since the inside of the channel 5 is dried immediately after cleaning in this way, the propagation of various germs can be prevented. Furthermore, when the cleaned endoscope 4 is hung and stored, water remaining in the channel 5 does not drip onto the floor and stain it.
また、この実施例においても送気ポンプ２４の

ンネル５をいためないようにするとよい。 Also in this embodiment, it is preferable to automatically adjust the amount of air fed by the air pump 24 and the heating temperature of the air so as not to damage the channel 5.
なお、本発明における減圧弁は上記ホース８に
設けてもよい。また、必要に応じて減圧弁のある
ホース８とないものとを交換するようにしてもよ
い。 Note that the pressure reducing valve in the present invention may be provided in the hose 8. Further, the hose 8 having a pressure reducing valve may be replaced with the hose 8 not having a pressure reducing valve, if necessary.

As explained above, according to the cleaning device of the present invention,
A tank to temporarily store tap water and a pump to send water from this tank to the channel of the endoscope are no longer required. Therefore, the structure can be simplified and downsized, and it can be manufactured economically. Also,
Since no water is stored in the tank, the growth of bacteria can be minimized.
