Description

[Detailed description of the invention] The present invention relates to an endoscope cleaning device.

Endoscopes become contaminated with use, and the surfaces and the inside of the ducts within the endoscope must be cleaned.

This cleaning is performed by not only cleaning the entire surface of the endoscope with a cleaning solution, but also injecting water into various pipes extending from the tip of the endoscope to the operating section or a part of the connector.

Conventionally, when cleaning the inside of a conduit of an endoscope, a connection mouthpiece of a cleaning device was fixed to an opening mouthpiece of the endoscope conduit, and a cleaning liquid was injected into the conduit. but.

Even if the inside of the pipe can be cleaned, it is impossible to clean the outside of the opening mouthpiece, and the outside of the first mouthpiece must be cleaned separately after cleaning the inside of the pipe.

An object of the present invention is to provide an endoscope cleaning device that can clean the outside of the mouthpiece in one cleaning operation when cleaning the endoscope channel.

Hereinafter, one embodiment of this invention will be explained in detail based on the drawings.

rc is inserted s2. An air pipe wI5 and a water pipe line 6 are disposed across the operating section 3 and the weight guide cable 4. The air supply pipe line 5 and the water supply pipe line 6 are connected to the endoscope insertion s2.
The two converge near the tip and are connected to the opening nozzle 7 provided at the tip of the insertion section 2.

A connector 9 is provided at one end of the light guide cable 4, and the air supply pipe line 5 branches into the connector 9, and first and second air supply caps 10 are arranged with an angle between them.
11 is provided.

The air supply mouthpiece lOK of ft1il has openings that communicate with the water supply pipe 61C arranged in parallel. The first air supply cap 10 is connected to the water supply tank 14, and the air supply pipe line 5 is connected to the air supply tube 15.
Then, the water supply pipe line 6 is connected to the water supply tube 16. Second
When the connector 9 is attached to the light source device, the air supply 11 is connected to an air pump (not shown) in the light source device. Similarly, the connector 1119 is provided with a suction mouthpiece 13 that is connected to a suction device (not shown), and the suction conduit 17 passing through the light guide cable 4 communicates with the suction opening/closing control valve 21 .

A forceps channel 18 for inserting a treatment tool is built into the insertion section 2 and the operation s3, and one end of the channel 18 is opened at the tip of the insertion section s2, and the other end is opened at the operation section 3, and the forceps plug is opened at the tip of the insertion section s2. 2o is provided. This channel 18 can be opened and closed in communication with the suction conduit 17 via the suction opening/closing control valve 21 .

Further, an air/water supply opening/closing control valve 22 is disposed midway between the air supply pipe line 5 and the water supply pipe line 6 to switch between the air supply line and the water supply line. When the air supply path is closed by this pipe switching, the air sent from the second air supply mouthpiece passes through the air supply tube 15, pressurizes the water IT [8] in the water supply tank, passes through the water supply tube 16, and enters the water supply tank. Water is injected from /zuru 7 via the water supply pipe 6v.

FIG. 82 shows an embodiment in which the present invention is applied to a connection mouthpiece 32 connected to a forceps plug 20 for cleaning a forceps channel 181. The forceps plug 20 projects and opens at the shoulder of the endoscope operating section 3, has a collar 25 integrally formed at its tip, and is provided with a concave groove 26.

A water pipe 30 is extended from the power and cleaning device, and an II connection cap 32 is fixedly installed at its tip. This mouthpiece 32 is attached to the front side wall 33 of the forceps plug 20@. The rear wall 34 on the water pipe 30 side, the front wall 33, and the outer WI wall 35 that connects and closes the entire g4 of the rear wall 34 form a U-shaped cross section. The front wall 33 has a circular opening 36 in the center, the inner diameter of which is smaller than the outer diameter of the collar 25.
It is formed larger than the outer diameter of the concave groove 26 and is made of an elastic material. The rear wall 34 has a hole V in the center with a diameter equal to the inner diameter of the water pipe 30! L, and is held watertight by adhesive or the like to the water pipe 30 on the outside thereof. Further, a partition wall 37 made of an elastic material is provided on the inner surface of the cap 32, spaced apart from the outer circumferential wall 35 and connecting the front @ wall 33 and the rear wall 34. The inner diameter formed by this partition wall 37 is slightly thicker than the outer diameter of the front wall 31.
4. A donut-shaped cavity layer 38 is formed around the base 32, surrounded by the outer 141135 and 11# walls 37.

A pressure pipe 39 that supplies fluid such as gas or liquid is connected to this cavity layer 38, and the other end of the pressure pipe 39 is connected to a three-way pipe 421 that communicates with a relief pipe 40 and a pump 41. A valve 43 is provided.

Also, the front wall side 33. Rear @ wall 34, partition wall 37, brim 3
A hollow storage chamber 44 is formed to serve as a connection portion that engages with the 1v return, and a cavity layer 3 is formed between the storage chamber 44 and the outside of the collar 31.
8 maintains a gap that is selectively opened and closed.

The operation of the connection cap 32 of the cleaning device having the IIC configuration as described above will be explained.

2(2)(a) is a state diagram in which the pressure inside the cavity layer 38 is released.

When cleaning the endoscope, the connection cap 32 is connected to the forceps plug 20.
I'm stuck in it. At that time, the front II wall 33 is elastically deformed and overcomes the 25 boxwoods of the forceps plug 20, and the brim 25 is moved over the accommodation chamber 4.
It is inserted within 4. The three-way valve 43 is now set to communicate with the pressure pipe 39 and pop 41 and close the relief pipe 40.

The pressure sent from the pop 41 causes the cavity layer 38 to expand. (FIG. 2(b)) The ring-shaped partition 37 transforms into the storage chamber 44 and comes into contact with the outer periphery of the forceps plug 200 and the collar 25, and by supplying sufficient pressure, the gap is kept airtight, and the cleaning device and endoscope The conduit is connected to the duct.

In this state, washing water is injected from the washing machine through the water pipe 30, and the washing water is injected only into the forceps plug 20, and the endoscopy is performed.
It flows through the suction conduit 17 and the forceps channel 18 to wash the inside thereof.

- 10,000, when flushing water is flowing, the pressure pipe 3 is connected to the three-way valve 43'.
9 and the relief pipe 40 and cut off the communication with the pop 41, the expansion of the cavity layer 38 is weakened, and a gap is again formed between the partition wall 37 and the relief pipe 40, and a branch separate from the inner pipe and the pipe is formed. The cleaning water flows through each channel. This side-flowing washing water washes the outside of the collar 25, washes the concave groove 26, and flows to the outside.

The connection cap 32 of the present invention is capable of switching the fik of the washing water from the washing device in two ways as needed by using a separately provided means during washing of the endoscope conduit, and allows the water to be internalized at the intended time. The inside of the scope tube and the outside of the mouthpiece can be cleaned.

In addition, in the example (in which the cavity layer 38 is pressurized, the gap is closed), but when negative pressure Y is applied to the cavity layer, a gap is maintained, and when the pressure is released, the gap is closed. You can also
Fasten the partition wall 37 with a fastener without using fluid pressure! Even if Ji is opened or closed, Yong JiJ can achieve its purpose.
