一般に、内視鏡には送気、送水を行なうための管路が組
み込まれている。したがって、使用済みの内視鏡を洗浄
する際にはその内視鏡の外表面ばかりでなく、その各管
路内も洗浄する必要がある。DETAILED DESCRIPTION OF THE INVENTION Generally, an endoscope includes a conduit for supplying air and water. Therefore, when cleaning a used endoscope, it is necessary to clean not only the outer surface of the endoscope but also the inside of each duct.

で洗浄するのが普通である。The cleaning referred to here includes washing with water to remove contamination inside the pipes, disinfection using a chemical solution after washing with water, and washing with water after disinfection. Normally, cleaning is performed in the above order. It is.

あった。By the way, conventionally, in the method of cleaning the inside of each pipe, a cleaning liquid injection tube is connected to the mouthpiece of each pipe, and the on-off valve of each pipe is operated to open the pipe. There is a need. In other words, it is necessary to individually connect a cleaning liquid injection tube to each pipe and to switch each on-off valve, making the cleaning operation complicated and troublesome. Furthermore, the above-mentioned conventional cleaning method has a serious drawback in that cleaning of the details of the valve body of the on-off valve and the portion covered by the valve body of the cylinder tends to be incomplete.

いる。Therefore, in order to solve the above-mentioned problems, cleaning liquid is supplied from an air/liquid cylinder installed in the operation section of the endoscope, and the liquid is sent to each pipe line to clean the inner peripheral surface of the cylinder and the inner surface of the cylinder. It has been considered to clean the surrounding surfaces at the same time. That is, the on-off valve inserted into the air/liquid feeding cylinder is removed, and the adapter is attached to the opened cylinder. Then, the liquid feeding tube connected to this adapter is connected to the liquid feeding pump, and the liquid from this liquid feeding I ring is supplied to the above cylinder via the adapter, and the liquid is sent from this cylinder to the liquid feeding pipe line and the air feeding pipe line. The liquid flows out from the nozzle at the distal end of the endoscope and from the air supply port body and liquid supply port body of the connector portion for cleaning.

できないという欠点がある。However, each duct of an endoscope has a different inner diameter. Specifically, in general, the air supply pipe and the liquid supply pipe are configured such that the pipe on the insertion section side of the endoscope is thin, and the pipe on the light guide cable side is thick. Therefore, even if liquid is sent from the cylinder that communicates these pipes, the cleaning liquid will concentrate in the pipes with low flow resistance, and will not flow sufficiently into the pipes with high flow resistance. In other words, there is a drawback that all the pipes cannot be reliably cleaned.

供することにある。The present invention has been made in view of the above-mentioned circumstances, and its purpose is to facilitate connection to each pipe line of an endoscope, and to ensure that each pipe line and the inside of the on-off valve cylinder are cleaned. It is an object of the present invention to provide a cleaning method for an endoscope conduit that makes it possible to clean an endoscope conduit.

First, as shown in FIG. 1, the plug body 25 is attached to the air/liquid supply on/off valve/cylinder 20, and the liquid supply tube 27 is connected to the first air supply port body 10 of the connector section 9. , cap 3
A connection port body 32 is attached to the second air supply port II and the liquid supply port body 12 to communicate with each other. When the air supply pump 30 is operated in this state, the inside of the liquid tank 28 is pressurized by the air from the air supply pump 30, so that the liquid is transferred from the liquid supply cheese 27 to the upstream pipe of the air supply pipe line 5. It is sent into the road section 5a. A part of the liquid sent here passes through the entire inside of the connection port body 32 and also flows into the upstream side pipe section 6a of the liquid sending pipe line 6. And each upstream pipe section 5a.
６ａに送り込まれた液体りは送気送液開閉弁用シリンダ

排出させることができる。Therefore, the entire length of all the pipe lines 5, 6 and the inside of the air/liquid supply on/off valve cylinder 20 are cleaned by this flow of liquid. Further, since the liquid flows in the direction of outflow from the nozzle 7, the dirt adhering to the nozzle 7 can be reliably discharged to the outside.

別々にノズル７に連通させる構造としてもよい。In addition, in the above-mentioned embodiment, the downstream side pipe sections 5b and 6b of the air supply pipe line 5 and the liquid supply pipe line 6 are merged to form one nozzle 7.
However, there are two nozzles 7' at the tip of the insertion section 2.
It is also possible to provide a structure in which the downstream side positive passage portions 5-b- and 6b are communicated with the nozzle 7 separately.

記シリンダ内を確実かつ一度に洗浄することができる。As explained above, in the present invention, the cylinder for the air/liquid feeding on/off valve is closed, and the liquid is fed from the air feeding port body in a state where the air feeding port body and the liquid feeding port body of the connector portion are communicated with each other. It was made to flow out from the nozzle of the insertion part. Therefore, the entire length of the air supply pipe and liquid supply pipe and the inside of the cylinder can be reliably cleaned at once by such a flow of liquid.

必要としないから作業性に優れる。In addition, since the liquid is forcibly fed through the connector part of each conduit and flows out from the tip of the insertion part, even if the inner diameter of each conduit is different between the insertion part side and the light guide cable side,
The entire length of each pipe can be reliably cleaned. In addition, since the liquid flows in the direction of outflow from the nozzle, dirt adhering to the nozzle can be reliably discharged, and furthermore, no special operation is required when feeding the liquid, resulting in excellent workability.
