Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope channel cleaning connector device for connecting to an endoscope-side mouthpiece in a cleaning device for cleaning an endoscope channel.

When cleaning the inside of an endoscope duct, it has been considered to connect connectors of a liquid feeding tube to various cylinders of the operating section and to send a cleaning liquid into the endoscope duct for cleaning. In this case, the conventionally considered connector was of a type in which the connector was inserted and engaged using a threaded portion formed on the inner circumferential surface of the cylinder mouthpiece. In other words, the tip of the connector is inserted into the inner hole of the cap, and an O-ring is fitted around the outer circumference of the tip of the connector, and this O-ring is inserted into the inner circumferential surface of the inner hole of the cap. The connection method was to ensure watertightness by making them stick together.

Therefore, in the structure of this conventional connector, since the tip of the connector is inserted into the inner hole of the base part, there is a part of the inner hole that does not come into contact with the cleaning liquid, that is, an inner surface part that is not cleaned. A lot of it remained and it became a problem.

The present invention has been made focusing on the above circumstances,
The purpose of this is to improve the cleaning effect of the endoscope by eliminating the unwashed part that remains in the inner hole of the mouthpiece when connecting the connector of the liquid feeding tube to the mouthpiece of the endoscope conduit. An object of the present invention is to provide a connector device for cleaning pipes.

Hereinafter, each embodiment of the present invention will be described in sequence based on the drawings.

Generally, an endoscope is equipped with various pipes for air supply, water supply, suction, etc., and the endoscope's operating section 1 includes a plurality of switching valve devices for switching and operating each of the pipes. are arranged in a straight line. FIG. 1 shows the cylinder portion of the switching valve device. That is, 2 is a cylinder of a switching valve device for air and water supply, and an air supply pipe line 3 and a water supply pipe line 4 are connected to this cylinder 2 for air and water supply. 5 is a cylinder of a suction switching valve device, and a suction pipe line 6 is connected to this suction cylinder 5. 7 is a cylinder of a switching valve device for gas such as carbon dioxide gas, and a gas pipe line 8 is connected to this cylinder 7 for gas. A valve mechanism 9 for opening and closing the gas pipe line 8 is built into the gas cylinder 7 . The valve mechanism 9 is opened by pushing in the valve body 11.
Moreover, each cylinder 2, 5, and 7 constitutes a mouthpiece when cleaning each endoscope channel, considering the above-mentioned configuration. Further, an engagement receiving portion consisting of flanges 12, 13, 14 is provided on the outer opening end periphery of each cylinder 2, 5, 6, and a piston (not shown) of each switching valve device is attached to this. A member to be held is engaged therein, and an endoscope channel cleaning connector device 15, which will be described later, is detachably engaged therein.

The endoscope channel cleaning connector device 15 is the second
It is constructed as shown in FIGS. That is, the reference numeral 16 in the figure is a rectangular parallelepiped connector body made of plastic material, and a support member 17 is bonded and attached to one surface of the connector body 16. As shown in FIGS. 2, 4, and 5, this support member 17 is provided with a long notch hole 18 cut out from one end along its longitudinal direction. The flange 12 of each cylinder 2, 5, 7 is attached to the periphery of the hole.
An engagement stepped portion 19 is formed as an engagement mechanism that engages the members 13 and 14. In addition, the engagement step portion 19
has a function as a rail for inserting and guiding each flange 12, 13, 14 into the notch hole 18 so as to fit therein. Each of the flanges 12, 13, and 14 is positioned within the cutout hole 18 and engaged with the engagement step 19 thereof. Furthermore, three guide holes 21, 22, and 23 are formed in the connector body 16, respectively, so as to correspond to the openings of the cylinders 2, 5, and 7 and pass through them. Cylindrical holders 27, 28, 29 having supply ports 24, 25, 26, respectively, are movably fitted into the guide holes 21, 22, 23. These holders 27, 28, 29 are connected to the connecting pipe 3.

An operating ring 34 is rotatably fitted around the outer periphery of the holder 28 located at the center. The operating ring 34 is configured to move integrally with the holder 28 while rotating at a fixed position. Further, a male thread 36 is formed on the outer periphery of the end of the operating ring 34 on the side of the connector body 16 and is screwed into a female thread 35 formed on the inner periphery of the inner hole 22 . By rotating the operating ring 34, the operating ring 34 moves along the axial direction of the inner hole 22 due to the screwing action of the male thread 35 and the female thread 36. Further, along with this movement, the holders 27, 28, 29 move together with the connecting tube 31. In addition, 37 is a stopper member that restricts the raised position of the operating ring 34, and the connector body 16
is attached to the top surface of the Furthermore, each holder 2
Ring-shaped seal members 38, 39, 40 made of an elastic material are attached to the end surfaces of the inner holes 21, 22, 23 of the inner holes 7, 28, 29 in a watertight manner, respectively. These seal members 38, 39, 40 are attached so as to protrude around each supply port 24, 25, 26, and are attached to each holder 2 as shown in FIG.
When 7, 28, 29 move forward (descend), the flanges 12, 1 of the opposing holders 27, 28, 29
By being pressed against the outer edges of cylinders 3 and 14, the supply ports 24, 25 and 26 are brought into watertight communication with the holes of the corresponding cylinders 2, 5 and 7, respectively. Further, the supply ports 24, 25, 26 of each holder 27, 28, 29 are provided with orifice pipes 42, 43, 44, respectively, to adjust the flow rates of the respective supply ports 24, 25, 26. ing. As shown in FIG. 2, a valve mechanism 45 is incorporated inside the gas holder 27, and its valve body 46 moves together with the protruding cylinder 47. The protruding tube 47 pushes the valve body 11 of the valve mechanism 9 in the gas cylinder 7, thereby opening both the valve mechanisms 9 and 45.

Next, a case in which the connector device 15 is used will be described. First, the operating ring 34 is rotated to retract the holders 27, 28, 29 into the inner holes 21, 22, 23 of the connector body 16, as shown in FIG. Next, the flanges 12, 13, and 14 from which the pistons on the endoscope side have been removed are inserted into the engagement step portion 19 from the open end of the notch hole 18.
At this time, the air/water supply cylinder 2 side is inserted first. Then, when the flange 12 of the air/water supply cylinder 2 hits the innermost end of the notch hole 18, it stops and is positioned. In other words, each holder 2
The supply ports 24, 25, and 26 of 7, 28, and 29 correspond to the openings of the air/water supply cylinder 2, the suction cylinder 5, and the gas cylinder 7, respectively. Therefore, the operation ring 34 is rotated again,
Next time, if you rotate it in the opposite direction, the female thread 35 and the male thread 36 will be
The operation ring 34 is lowered by the screwing action of the holders 27, 28,
29 also descends. Since the state shown in FIG. 6 is reached, each seal member 38, 39, 40 is connected to the opposing flanges 12, 1, respectively, as shown in FIG.
It presses against the outer edge surface of 3 and 14. That is, it is pressed against the outer edge of the cylinders 2, 5, 7 except for the inner surface of each hole, and the supply ports 24, 25, 26 are watertightly communicated with the corresponding holes of the cylinders 2, 5, 7.
In this way, since the seal members 38, 39, and 40 are brought into elastic pressure contact, the reaction force is generated on the flange 1.
2, 13, and 14 are pressed into contact with the engagement step portion 19 and are securely fixed. In addition, the valve mechanism 9 of the gas cylinder 7
The valve body 11 has a supply port 26 in its connected state.
Since the valve body 46 of the side valve mechanism 45 is in contact with the valve body 46, the respective valve mechanisms 9 and 45 open together and communicate with each other. After the connector device 15 is connected to each cylinder 2, 5, and 7 in this way, cleaning water, disinfectant solution, rinsing water, and draining air are sequentially sent through the cleaning liquid feeding tube 33 to each pipe line 3. ,4,6,
