Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope duct cleaning method for cleaning various ducts built into an endoscope.

Generally, endoscopes are equipped with various pipes for air supply, water supply, suction, and the like. Therefore, in order to clean a used endoscope, it is necessary to clean not only the external surface of the endoscope but also the inside of each duct. Here, "cleaning" refers to washing with water to remove contamination inside the pipes, and cleaning with a chemical solution after washing with water, and
This disinfection is followed by washing with water, and it is normal to wash in the above order. 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 opened and opened. There is a need. In addition, it is necessary to individually connect the cleaning liquid injection tube to each conduit 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 that the 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.

Therefore, the present applicant has proposed a cleaning device for the endoscopic 08 W tract which has already solved the above-mentioned problems.
The application has been filed as No. This is done by supplying cleaning liquid from the air/liquid cylinder and the suction 7 cylinder provided in the operation section of the endoscope, and sending the liquid to each pipe line to clean the inner circumferential surface of the pipe line and the inner circumferential surfaces of the above-mentioned two cylinders. This allows them to be washed at the same time.

That is, the opening/closing valves inserted in the air/liquid feeding cylinder 7 and the suction cylinder are 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 the liquid feeding pump is supplied to each of the above cylinders through the adapter, and the liquid is fed from this cylinder. The liquid is sent to the endoscope's distal end, the air supply port of the nozzle and connector, the liquid supply port, and the suction port for cleaning. .

However, the inner diameter of each of the internal and external conduits is the nave. To be more specific, the air supply pipe and liquid supply pipe are generally thin;
The suction line is thick, but even in these same lines, the endoscope insertion section llTi0 line is thin, and the light guide cable...
I] has a thick conduit. 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.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to facilitate connection to the inner 1υ U-paths, and to reliably clean the insides of each conduit and the on-off valve cylinder. 4 cleaning methods for endoscope channels
There are four servings.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, insert the An air supply line 5 and a liquid supply line 1 6 are arranged across the unit 2, the operation unit 3, and the light kite cable 4. Ten people are arranged at the air line 5 and the liquid line 6. The tips of the air line 5 and the liquid line 6 join together. The air/liquid feeding nozzle 7 is connected to the air/liquid feeding nozzle 7 provided at the tip of the insertion portion 2, and the air/liquid feeding nozzle 7 is connected to the air/liquid feeding nozzle 7 provided at the tip of the insertion portion 2.

) is immersed toward the outside of the F&rtcr, and sprays cleaning fluid and air toward the outside surface of the canopy. A connector portion 9 is provided at the extending end of the light guide cable 4, and the connector portion 9 has first and second air supply bodies 10 communicating with the taste duct 5.
, 11, a liquid feeding body 12 which communicates with the liquid feeding pipe line 6, and a suction body I3 which connects to a suction pipe line which will be described later. The first air supply body 10 is connected to the internal air pump in the light source device (not shown) when the connector portion 9 is attached to the light source device (not shown). The second air supply port body II and the liquid supply port Z2 are each connected to an aromatic liquid tank (not shown).Furthermore, the suction port body 13 is connected to an aspirator (1
I don't show it. ).

On the other hand, a suction conduit 15 is inserted and disposed inside the insertion part 2, the connecting part 3, and the light guide cable 4. It is formed as a channel for i+lq.The tip of the channel for inserting the tool 16" opens into the suction port 17 at the tip of the insertion section 2 [Y stroke, and the base end of the channel for passing the tool 16" opens for operation. The portion 3 is opened to the outside to form a forceps mouth body I8.This forceps mouth body 18 is closed with a removable plug body 18a.

Note that Z6 is a sub-liquid feeding body having a check valve I6a, which communicates with the liquid feeding pipe line 6.

Furthermore, the treatment instrument insertion channel is the suction/# path I5.
It is connected to the @rui side via a suction on/off valve cylinder 19. Further, an air/liquid supply opening/closing valve cylinder 20 is inserted between the air supply pipe line 5 and the liquid pipe line 6.

The cylinders 19 and 20 for the on-off valves are arranged adjacent to each other on the side surface of the operating section 3. This suction on-off valve cylinder 19 has a cylindrical shape with a bottom, and a flange 273 is integrally provided at the opening edge thereof. Further, the air/liquid supply on/off valve cylinder 2o similarly has a cylindrical shape with a bottom, and a flange 24 is integrally provided at the opening edge thereof.

A plug body 25,26 is attached to each of the on-off valve cylinders 19,20 to close the open end. A retaining groove 29.30 is cut into the inner circumferential surface of each plug body 25.26 and engages with the flange 23.24.
Even if the internal pressure of 9.20 increases, the plugs 25 and 26 will not come off. Note that a piston (not shown) is usually inserted into each of the seven rings 19.degree.
, 6a, 15a and the downstream pipe sections 5b, 6b, 15b can be communicated with or disconnected from each other, but the piston must be removed before attaching the plug body 25, 26.

On the other hand, one end of the liquid feeding tube 30 is connected to the sub liquid feeding port body I6. The other end of this liquid feeding tube 30 is hermetically inserted into an M, f* tank 31 containing a liquid reservoir, and its end is immersed in the liquid reservoir. Further, the other end of a pressure tube 33 having one end connected to an air supply pump 32 is airtightly inserted into the liquid tank 3I, and its end opens into the upper space within the liquid tank 31. Therefore, when the air supply pump 32 operates, the inside of the liquid tank 31 is pressurized and the liquid is sent out from the liquid supply tube 30. Furthermore, the first air supply port body 10 and the suction port body 13 of the connector portion 9 are communicated with each other through a connecting tube 34 . Moreover, the second air supply port body ZI and the liquid supply port body 1

Further, the first air supply port body 10 and the suction body 13 of the connector portion 9 are communicated with each other through a connecting tube 34, and the mouthpiece 3
A cap 36 is attached to the cap 5 to close the second air outlet body 1. In this state, the air supply pump 32 is operated to pressurize the inside of the liquid tank 31, thereby transferring the liquid to the sub-liquid supply port body I.
6, the check valve 16a is pushed open to allow the liquid to flow into the downstream side pipe section 6b of the liquid sending pipe line 6. A portion of the liquid flowing into the downstream pipe section 6b flows out from the nozzle 7, and most of the remaining portion flows into the cylinder 20 for the air/liquid feeding valve. The liquid that has flowed into the cylinder 20 flows into the downstream side pipe section 5b of the air supply pipe line 5 and flows out from the nozzle 7, and also flows into the upstream side pipe line 5a of the air supply pipe line 5 and the liquid supply pipe line 6.

Flows to 6a. The liquid flowing into the downstream side pipe section 6a of the liquid sending pipe 6 flows through the liquid sending port body I2 and the through hole 37 of the cap 36.
flows out through the Moreover, the upstream fu of the air supply pipe line 5
The liquid flowing into the pipe section 5a is transferred to the first air supply port body 10.
It passes through the connecting tube 34 and flows from the suction port body 13 into the upstream pipe section 1511 of the suction pipe line 15 . The liquid flowing here passes through the suction on-off valve cylinder 19, flows through the downstream pipe section 15b of the suction pipe I5, and flows out from the suction port 17.

This flow of liquid thus cleans the entire length of all lines 5, 6.15 and the inside of each cylinder 1.9.20. Also, liquids # and L flow in the direction of outflow from the nozzle 7 and the suction port I7, but these nozzles 7 and the suction port I
The dirt adhering to 7 can be reliably discharged to the outside.

In the above embodiment, the downstream pipe sections 5b and 6b of the air supply pipe 5 and the liquid supply pipe 6 are merged to communicate with one nozzle 7, but two nozzles are provided at the distal end of the insertion section 2. set 7,
Each downstream pipe section 5 b r 6 b is connected to the nozzle 7 separately.
The liquid may be delivered using a so-called syringe, into which a syringe is inserted.

In addition, the liquid in the cloth example above is water or a chemical solution, and when a chemical solution is used, it is generally called emotion, but the cleaning referred to here includes so-called washing with water and disinfection.

Furthermore, by making a small hole in the stopper 18a attached to the forceps mouth body 18 and allowing the liquid to flow out slightly from the hole, the inner circumferential surface of the forceps mouth body I8 can be cleaned well. . As for the second air supply port body 11, if a small hole is made in the cap 36 so that a small amount of liquid can flow out, the inner peripheral surface of the second air supply port body 11 can be cleaned well.

As explained above, the present invention closes the cylinder for the air/liquid supply on-off valve and the ring for the suction on/off valve, and
The air supply port of the connector part and the suction port were communicated, and the liquid was sent from the sub-liquid supply port of the operation part, and the liquid was discharged from the suction 1], the nozzle, and the liquid supply port. Therefore, since the liquid can flow through the entire length of each pipe line and into each cylinder, it is possible to reliably clean each pipe line and each cylinder at the same time and even as the inner diameter of each line increases. can. In addition, since the liquid flows out from the nozzle and the suction port, dirt adhering to these nozzles and the suction port can be discharged to the outside.Furthermore, there is no need for immediate operation during cleaning, making the work easier. It is suggested.
