Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe brushing cover for an endoscope used for cleaning a pipe provided in the endoscope with a cleaning brush.

[0002]

2. Description of the Related Art It is desirable that the inside of a pipe provided in an endoscope be brushed and cleaned through a cleaning brush every time an endoscope inspection is completed.

[0003] Such brushing operations have conventionally been
This has been done by simply inserting and removing a cleaning brush having a brush portion attached to the tip of a flexible shaft portion from the open end into the pipe of the endoscope.

[0004]

However, when brushing in the pipe is completed and the cleaning brush is pulled out of the pipe, dirt in the pipe is scraped out and scattered at hand, and the surrounding environment and the operator's body are damaged. There is a risk of contamination.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pipe brushing cover for an endoscope which can clean the brushing of the pipe of the endoscope in a sanitary manner without contaminating the surroundings.

[0006]

In order to achieve the above object, a pipe brushing cover for an endoscope according to the present invention comprises a brush portion of a cleaning brush passed through a pipe provided in the endoscope. It is formed into a cap shape large enough to accommodate, and is detachable from the outside with respect to the endoscope so that the mouth side covers the open end of the pipe, and passes through the shaft of the cleaning brush so that it can advance and retreat in the axial direction. A shaft passage hole for allowing the shaft to pass through is formed on the other end side.

[0007] An engaging means which can be detachably provided at an opening end portion of the pipe of the endoscope may be provided at a mouth portion to connect a suction pipe or a water supply pipe so as to communicate with the internal space. May be provided.

The shaft passing hole may be provided with a sealing means for sealing a gap between the shaft passing hole and the shaft portion of the cleaning brush passing therethrough.

[0009]

Embodiments of the present invention will be described with reference to the drawings. FIG. 5 shows the overall configuration of the endoscope,
Denotes an insertion unit to be inserted into the body, 2 denotes an operation unit held by an operator, and 3 denotes a connector unit connected to the light source device.

[0010] The endoscope is provided with a pipe for inserting and removing the treatment tool and other various pipes, and a cleaning brush 10 is inserted into and removed from each pipe after each endoscope inspection. Then, brushing cleaning is performed.

For example, a cleaning brush 10 is inserted into the treatment tool insertion channel from the treatment tool insertion port 4 or the treatment tool protrusion port 5, and a suction operation valve 6 and a suction base 7 are inserted into a suction pipe.
A cleaning brush 10 is connected to the air supply / water supply pipe from the water supply base 8.
Is inserted.

FIG. 1 shows a state in which brushing inside the pipe 100 of an endoscope is performed by using the brushing cover 50 of the first embodiment of the present invention. The brush part 10a passed through the pipe 100 of the endoscope is configured to be attached to the tip of a flexible shaft part 10b.

The cover body 5 of the brushing cover 50
1 is formed of a transparent plastic material or the like, for example, in a cap shape large enough to accommodate the brush portion 10a of the cleaning brush 10.

The diameter of the cover body 51 is the same as that of the brush 10a.
Is a few millimeters, for example, about 1 centimeter, and the length is, for example, about 5 to 15 centimeters, while the brush part 10a is 1 to 2 centimeters.

A female screw 52 formed at the mouth of the cover main body 51 is engaged with a male screw formed on the endoscope side around the open end 100a of the pipe 100 so as to be freely engaged and disengaged.
The cover body 5 covers the open end 100a of the pipe 100.
1 can be attached and detached.

In this state, as shown in FIG. 1, a sealing O-ring 5 is disposed adjacent to the threaded portion.
3 is crushed, and the connection between the open end 100a of the pipe 100 and the cover body 51 is sealed.

On the other end side (top side) of the cover body 51,
A shaft passage hole 54 for allowing the shaft portion 10b of the cleaning brush 10 to pass therethrough is formed through the shaft position. The shaft passage hole 54 of this embodiment is provided in the brush portion 1 of the cleaning brush 10.
0a cannot pass, but the shaft portion 10b is formed to have a diameter that allows it to pass loosely.

When brushing the inside of the pipe 100 with the cleaning brush 10, the brushing cover 50 having the above-described configuration is configured such that the shaft portion 10 b of the cleaning brush 10 is passed through the shaft passage hole 54 in advance. And then Figure 1
, The cover body 51 is attached to the open end 100a of the pipe 100.

In this state, the inside of the pipe 100 is brushed with the brush portion 10a of the cleaning brush 10, and finally the brush portion 10a is pulled out from the open end 100a.
Even if the filth jumps out of the opening end 100a of 00, it does not scatter outside the cover main body 51, so that brushing cleaning can be performed hygienically. In addition, if the cover main body 51 is formed of a transparent member, the inside of the cover main body 51 can be checked from the outside, which is convenient.

After brushing is completed, the brushing cover 50 is gently removed from the open end 100a of the pipe 100, and the cleaning brush 10 is removed.
, And the cleaning brush 10 and the brushing cover 50 may be separately washed.

FIG. 2 shows a brushing cover 50 according to a second embodiment of the present invention. The cover body 51 is formed of a resilient material such as rubber or the like. The base 101 provided at the opening end 100a is elastically deformed so as to be detachable.
Others are the same as the above-mentioned first embodiment.

FIG. 3 shows a brushing cover 50 according to a third embodiment of the present invention, in which a connection mouthpiece 56 to which a suction tube 60 and the like can be connected is projected from a side wall of a cover body 51. The suction tube 60 and the internal space of the cover main body 51 are communicated with each other, so that the dirt jumping out of the pipe 100 can be suctioned and discharged.

In this embodiment, a sealing O-ring 5 is provided in the gap between the shaft portion 10b of the cleaning brush 10 and the shaft passage hole 54 so that suction leakage does not occur.
5 is attached. Note that a water supply tube may be connected instead of the suction tube 60 to drain the water from the other end of the pipe 100.

FIG. 4 shows a brushing cover 50 according to a fourth embodiment of the present invention. And the same connection base 56 as that of the third embodiment.
Is also provided. 1a is an observation window. Shaft passage hole 54
Are simple holes that elastically adhere to the shaft portion 10b of the cleaning brush 10.

With this configuration, the present invention can be applied to brushing into a pipe 100 having a mouth at the tip of the insertion section 1 of the endoscope, such as a treatment tool insertion channel or an air / water supply channel. In addition, brushing cleaning can be performed hygienically.

The cover body 51 is inserted into the insertion section 1 of the endoscope.
The cover body 51 may be loosely placed over the end of the cover and the operator may hold the cover body 51 by hand. This is also in the category of “detachable” in the present invention, and other pipe open ends 100a
The same applies to the coating on.

Further, if the pipe brushing cover of the endoscope of the present invention is used for a cytodiagnosis brush, it is possible to prevent dirt and the like from scattering from the treatment instrument insertion channel at the time of cell collection.

[0028]

According to the present invention, the brushing cover of the present invention is attached to the open end of the pipe of the endoscope, the inside of the pipe is brushed with a cleaning brush, and finally, the brush portion can be pulled out from the open end of the pipe. For example, since the dirt protruding from the opening end does not scatter out of the cap-shaped brushing cover, brushing cleaning can be performed hygienically without contaminating the surroundings.
