Therefore, the present applicant has already filed an application in Japanese Patent Application No. 111940/1983 for an endoscope/d tract cleaning instrument that solves the above-mentioned problems. This is done by cleaning tKk from the air and liquid supply cylinder and suction cylinder provided in the operation section of the endoscope.
The inner peripheral surface of the valley pipe and the circumferential surfaces of both cylinders can be simultaneously cleaned by supplying the liquid to the valley pipe. That is, the on-off valves inserted into the air/liquid feeding cylinder and the suction cylinder are removed, and the open/closed cylinders are fitted with a catcher metal. Then, connect the feeding ridge cheep connected to this adapter to the liquid feeding pump, and supply the liquid from this liquid feeding pump to each cylinder mentioned above through the adapter 7'', and from this cylinder to the liquid feeding pipe line, The liquid is sent to the tracheal channel and suction channel and flows out from the suction port at the tip of the endoscope, the air supply port at the nozzle and connector, the liquid supply port, and the suction port for cleaning. There is.

Next, each duct of the endoscope 1 is cleaned on the arm side. First, as shown in Fig. 1, the valley cylinders 19, 20.2
At the same time, the plugs 32, 33, and 34 are attached to the end portion 2a of the insertion portion 2, and the connector portion 9 is enclosed in a connecting cylinder 39 that connects to the liquid reservoir 42 with the cap 35ff attached to the distal end portion 2a of the insertion portion 2. If you operate the suction pump f38f in this state,
Due to the suction force, the air supply pipe 5, the downstream pipes 95a and 6a of the liquid supply pipe 6, and the upstream pipe i7b of the suction pipe 2, which communicate with the nozzle 8 and the suction port 17, become negative pressures. When the downstream pipe parts 5a and 6a of the air supply pipe line 5 and the liquid supply pipe line 6 become negative pressure, the inside of the cylinder 20 for the air and liquid supply opening/closing valve to which these are connected becomes negative pressure. upstream pipe section 5b
, 6b also becomes negative pressure. Furthermore, when the downstream pipe section 5b of the air supply 'σ path 5 becomes negative pressure, the gas supply pipe 22 communicating therewith becomes
The downstream pipe portion 22b becomes negative pressure. Therefore, the pressure inside the gas supply on-off valve cylinder 25 to which this downstream pipe section 22b is connected and the upstream pipe section 22a of the gas supply pipe line 22 connected to this cylinder 25 becomes negative pressure. Further, when the upstream/U section 7b of the suction pipe line 7 becomes negative pressure, the inside of the suction on-off valve cylinder 19 communicating therewith and the downstream pipe part 7a of the suction pipe line 7 communicating therewith also become negative pressure.

In this way, when the entire length of each conduit 5, 6, 7.22 and the inside of the valley cylinder 19, 20.25 become negative pressure, liquid flows into the said valley conduit 5, 6, 7.22. In other words, the connecting cylinder 39 is not under negative pressure, and the liquid in the liquid tank 42 is passed through the connecting cylinder 39 to the first port of the connector section 9. 2nd air outlet body 1
It flows into the upstream pipe section 5b of the air supply pipe line 5 from 0°11, and also flows into the upstream pipe part 6b of the liquid supply pipe line 6 from the liquid supply port body 12. Furthermore, the downstream pipe section 7a of the suction pipe line 7 from the suction port body 13
It also flows into the upstream pipe section 22m of the gas feed pipe line 22 from the gas feed throat body 14. Upstream pipe section 5b of air supply pipe line 5 and liquid supply pipe line 6.

6bに泥大した液体は送気送液開閉弁用シリンダ20内

Further, the liquid that has flowed into the downstream pipe section 7b of the suction pipe line 7 from the suction body 13 is ejected into the suction on/off valve cylinder 19, passes through the upstream pipe section 7a from there, and enters the cap fss from the suction port 17. The liquid flows out to the can 035, passes through a suction cheep 37 connected to this can 035, and is sucked into a suction pump 38.

Furthermore, the liquid that has flowed from the gas-containing gas flow body 14 into the upstream pipe section 22a of the gas feed pipe line 22 is transferred to the gas feed opening/closing valve cylinder 25.
The downstream pipe section 22 flows through the interior as shown by the arrow in FIG.
This leads to b. The liquid that has flowed into the downstream pipe section 22b passes through the downstream pipe section 5a of the air supply pipe line 5, flows out from the nozzle 8 into the cap 35, and is sucked through the suction tube 37 connected to this cap 35. It is attracted to σ.

したがって、このような液体の流れにより、各管路5,

As explained above, the present invention closes the cylinder for the air and liquid supply on-off valve, the cylinder for the suction on-off valve, and the cylinder for the gas supply on-off valve, and connects either the tip or the connector to the liquid tank. Since the liquid is connected and sucked from the other side and distributed to each pipe and cylinder, it is possible to flow the liquid throughout the entire length of each pipe and into each cylinder, even if the pipes have different thicknesses. The water can be flushed reliably, and each of the above-mentioned U passages and each cylinder can be cleaned well and easily.
