定水圧で水を送り出すようにしている。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 uses a water pump to pump the water into each channel of the endoscope. It is supposed to be sent to The reason why the water supplied from the water faucet is temporarily stored in the water storage tank is because the channel tube of the endoscope generally has a lower pressure than the water flowing out from the water faucet, and if the water is pumped directly into the channel, the channel tube will burst. be. Therefore, the water pump is designed to pump water at a constant water pressure within the tolerance range of the channel of the endoscope.

4 incorporates a valve body 16 urged 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 urging force of the spring 15 are balanced. and,
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 lowers the pressure to a predetermined level and sends out the pressure.
そして、この所定の圧力としては内視鏡４のチャンネル

, when opened, tap water is fed through the hose 8 and the main cleaning 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 is first reduced in pressure by the pressure reducing valve 14 to a pressure within the tolerance range of the channels 5 of the endoscope 4. By sending this depressurized water into each channel 5..., the inside of each channel 5... is cleaned, and the inside of the cleaning tank 3 is flushed from each other end of each channel 5... leaks to.

５内に残存する水が床にたれて汚すことがない。FIG. 5 shows a fourth embodiment of the invention. In this embodiment, in addition to the channel cleaning pipe section 12 in the first embodiment, a pipe switching section 2 is provided on the upstream side of the pressure reducing valve 14.
Insert 2. Then, the water removal air pipe line 23 is connected via this pipe line switching section 22. 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. Therefore, in this embodiment, by switching the channel 5 of the endoscope 4 to the channel switching section 22t after cleaning, the air sent from the air pump 24 can be sent into the channel 5 to drain water. Further, since this air is heated by the heater 25, the inside of the channel 5 can be quickly dried. In this way, since the inside of the channel 5 is immediately dried after cleaning, the proliferation of various germs can be prevented. Further, when the cleaned endoscope 4 is hung and stored, water remaining in the channel 5 does not drip onto the floor and contaminate it.

製作できる。As explained above, the washer of the present invention eliminates the need for a tank for temporarily storing tap water and a pump for conveying water from this tank to the channel of the endoscope. therefore,
The structure can be simplified and miniaturized, and it can be manufactured economically.
また、上記タンクに貯水しないので、雑菌の繁殖も極力
少なくできる。Furthermore, since water is not stored in the tank, the proliferation of bacteria can be minimized.
