Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention provides an internal inspection method for sealing the opening of a cylinder after an operating valve is removed from a cylinder connected midway through a fluid pipeline in order to clean the fluid pipeline. Regarding a mirror cleaning adapter.

0002

2. Description of the Related Art Generally, in an endoscope, an air/water supply operation valve for controlling air and water supply and a suction operation valve for controlling suction are provided in the operation section.

[0003] In the conventional endoscope cleaning adapter,
A plurality of plugs for sealing the opening of each cylinder were simply connected together by a connecting plate (Japanese Patent Application Laid-Open No. 59-1989-1).
129047).

0004

[Problems to be Solved by the Invention] If a plurality of plug bodies are simply connected in a single chain using a connecting plate, when one plug body seals the opening of one cylinder, the other plug bodies will close the opening of the other cylinder. It does not necessarily mean that the opening is reliably sealed. However, since these plugs are fixed to the operation part even in such an incomplete state, the user may accidentally pour the cleaning liquid into the pipe line, causing the cleaning liquid to leak from the cylinder opening that is not securely sealed. Sometimes it erupted into the surrounding area.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an endoscope cleaning adapter in which all cylinder openings are reliably sealed and there is no possibility that cleaning liquid or the like will spout out.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the endoscope cleaning adapter of the present invention has an operating valve connected in the middle of a fluid pipeline so that it can be detachably attached from the outside. In order to flush the fluid pipes of an endoscope with a plurality of cylinders arranged side by side in the operation section, an inner part is provided for sealing the opening of the cylinders from the outside after the operation valve is removed. The endoscope cleaning adapter is detachably attached to a first cylinder of the plurality of cylinders,
A main plug body for sealing the opening of the first cylinder, a slave plug body for sealing the openings of cylinders other than the first cylinder, and the main plug body is attached to the first cylinder. Accordingly, the present invention is characterized in that a forced sealing means is provided for guiding the slave plug to an opening of a cylinder other than the first cylinder and forcibly sealing the opening.

[0007]

[Embodiment] An embodiment will be described with reference to the drawings. In FIG. 1, reference numeral 1 indicates a frame above the operating section of the endoscope, in which a suction cylinder 10 and an air/water supply cylinder 20 are provided side by side with openings facing outward. 11 and 21
are nuts that fix each cylinder 10, 20 to the frame 1.

The suction cylinder 10 is normally located midway between a source suction line 12 that is connected to a suction device and a distal side suction line 13 that is connected to a suction port that opens at the tip of the insertion section of the endoscope. It is connected to the.

The air and water supply cylinder 20 has a source side air and water supply pipe 22 that is normally connected in communication with an air and water supply device, and a destination that is connected in communication with an air and water supply port that opens at the tip of the insertion section of the endoscope. It is connected midway to the side air and water supply pipe line 23.

Further, each cylinder 10, 20 is detachably equipped with a suction operation valve and an air/water supply operation valve (not shown), and FIG. 1 shows a state in which these operation valves are removed. .

Reference numeral 30 indicates an endoscope cleaning adapter according to an embodiment of the present invention, and reference numeral 31 indicates a cleaning adapter for an endoscope that is removably screwed into a threaded portion formed around the entire circumference of the tip of the suction cylinder 10. 10; and a rubber packing 33 that seals the opening of the suction cylinder 10 by being sandwiched between the screw fitting 32 and the opening of the suction cylinder 10. It is. The rubber packing 33 is attached to the screw fitting 3 as shown in FIG.
2 and is attached so as not to come off from the screw fitting 32.

[0012] Reference numeral 35 is a resilient rubber stopper that is pushed into the air and water cylinder 20 from the opening of the air and water cylinder 20 to seal the mouth of the air and water cylinder 20. , is provided in the opening of the air/water supply cylinder 20 so as to be freely insertable and removable.

Reference numeral 37 denotes a metal or plastic connecting plate (forced sealing means) that connects the screw fitting 32 and the follower 35, one end of which is fitted into the constriction 32a of the screw fitting 32. . In this fitting part, as shown in FIG.
a is formed on the connecting plate 37, and by pushing the constricted portion 32a deep into the slit 37a with strong force, the screw fitting 32 and the connecting plate 37 are connected so as not to come apart.

As also shown in FIG. 1, the connecting plate 37
The hole 37b formed on the other end side loosely fits into the narrow diameter portion 35a of the head of the follower plug 35, and the connecting plate 37 abuts the step between the hole 37b and the large diameter portion 35b on the inside thereof. , connecting plate 37
acts to forcibly push the follower plug 35 into the air/water supply cylinder 20.

[0015] Therefore, each fluid conduit 12, 13, 22
, 23 to clean the inside of the pipe, as shown in FIG.
2 into the suction cylinder 10, the opening of the suction cylinder 10 is sealed by the rubber packing 33 of the main plug 31, and at the same time, the connecting plate 37 causes the slave plug 35 to be inserted into the opening of the air/water supply cylinder 20. By being forcibly pushed in, the opening of the air/water supply cylinder 20 is sealed.

As a result, the main stopper 31 is removed from the suction cylinder 10.
As long as it is securely attached to the cylinder, even if cleaning liquid or the like is flowed through the suction pipes 12, 13 and the air/water supply pipes 22, 23, the cleaning liquid will not be ejected from the cylinder opening.

It should be noted that the present invention is not limited to the above-mentioned embodiments; for example, the function and number of each cylinder can be changed depending on the use of the endoscope.

[0018]

According to the endoscope cleaning adapter of the present invention, when the main stopper is attached to the first cylinder, the slave stopper is guided to the opening of the cylinder other than the first cylinder by the forced sealing means. Since the cylinder openings are forcibly sealed, by attaching the main plug, all cylinder openings are reliably sealed at the same time with a simple operation, and the spraying of cleaning liquid during fluid pipe cleaning is prevented. can be easily prevented.
