Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a cleaning device for cleaning a used and dirty endoscope.

[Technical background of the invention and its problems]

In general, when an endoscope is used, dirt and blood from the patient's body cavity adhere to its surface, so if it is not cleaned after each use, there is a risk of serious accidents such as in-hospital infections. There is. Therefore, various methods have been adopted to clean used endoscopes.

Conventionally, as a means for cleaning an endoscope, for example, a cleaning liquid is stored in a cleaning tank having an open top, and the endoscope is placed inside the tank and an operator cleans the endoscope. However, with this method, the operator has to scrub off the dirt and grime adhering to the endoscope, which not only results in poor work efficiency, but also prevents the entire surface of the endoscope from being rubbed uniformly, resulting in dirt and debris being removed. There were cases where I ended up staying.

Furthermore, as another means, a cleaning device has been developed that can perform automatic cleaning instead of the manual operation described above. However, automatic cleaning equipment not only has the drawback of being extremely expensive as it requires pumps and various control equipment, but also has the disadvantage that the entire equipment is large, making it difficult to secure a space for installation, for example, because it cannot be installed in an examination room. The disadvantage is that it becomes difficult.

[Purpose of invention]

The object of this invention is to provide an endoscope cleaning device that can easily and reliably clean an endoscope without using expensive and large equipment.

[Summary of the idea]

In this device, a holder for hanging an endoscope is provided on the inner surface of the upper end of a cleaning container whose interior is a accommodating part, and the holder is movable up and down in the accommodating part, and the endoscope is passed through the inner periphery of the holder. The endoscope is cleaned by providing a cleaning ring with jet holes bored in the inner circumferential surface, and by moving the cleaning ring up and down and spouting cleaning fluid from the jet holes.

[Example of idea]

An embodiment of this invention will be described below with reference to FIGS. 1 to 3. The cleaning device shown in FIG. 1 includes a rectangular box-shaped cleaning container 2 with a housing section 1 inside. One side of the cleaning container 2 is open, and a lid plate 3 is provided on this opening so that it can be opened and closed. A packing 4 is attached to the periphery of the inner surface of the cover plate 3, and when the cover plate 3 is closed and fixed with metal fittings (not shown), the packing 4 comes into pressure contact with the periphery of the opening surface of the cleaning container 2, and It is designed to maintain liquid tightness between the parts.

Further, a cleaning ring 5 formed of a pipe is provided horizontally within the cleaning container 2.
A receiving member 6 is fixed to the outer peripheral surface of the cleaning ring 5, and this receiving member 6 is a guide provided over the entire length in the vertical direction on the inner surface of the side plate facing the side surface on which the lid plate 3 of the cleaning container 2 is provided. It is slidably engaged with the rail 7. Furthermore, a knob 8 is provided on the outer circumferential surface of the cleaning ring 5 so as to protrude from the receiving member 6 at a position offset by approximately 90 degrees in the circumferential direction. An insertion groove 9 is formed in the side plate of the cleaning container 2 facing the knob 8 over the entire length in the vertical direction. The insertion groove 9 is closed with an elastic membrane 10 made of rubber or the like having a slit 10a cut therein, and the knob 8 projects outward from the insertion groove 9 through the elastic membrane 10 in a liquid-tight manner. Therefore, this knob 8 allows the cleaning ring 5 to be moved up and down along the guide rail 7. Note that a shielding plate 10b is attached to the end of the knob 8 located inside the housing part 1, and a cleaning liquid, which will be described later, is scattered to the outside through a gap created between the periphery of the shaft-shaped knob 8 and the elastic membrane 10. It prevents

Further, a large number of elongated ejection holes 11 are bored in the inner circumferential surface of the cleaning ring 5 along the circumferential direction at predetermined intervals in the circumferential direction. Further, a first connection port body 12 is provided protruding from the cleaning ring 5, and a second connection port body 13 is provided at the upper part of the side plate of the cleaning container 2 so as to pass through the side plate. One end of the first connection port body 12 and the second connection port body 13 is, for example, a first supply hose 1 that is spirally wound and expandable.
Connected by 4. One end of a second supply hose 15 is connected to the other end of the second connection port body 13 . The other end of the second supply hose 15 is connected to a liquid source (not shown), such as a water faucet. Therefore, by opening the faucet, tap water, which is a cleaning liquid, is supplied to the second and first supply hoses 15 and 1.
4 to the cleaning ring 5, and is ejected from an ejection hole 11 bored in the inner circumferential surface of the cleaning ring 5. Note that a drainage hose 16 is provided at the bottom of the cleaning container 2.
is connected so that the cleaning liquid spouted from the cleaning ring 5 is discharged.

On the other hand, a holder 17 having a substantially J-shape, for example, is provided at the center of the inner surface of the upper end of the cleaning container 2 . An endoscope 18 is suspended from this holder 17 by engaging the proximal end of a light guide cable 19, and the insertion portion 20 and the distal end of the light guide cable 19 are attached to the inner peripheral side of the cleaning ring 5. It is inserted.

According to the cleaning device having such a configuration, when the used and dirty endoscope 18 is suspended in the housing part 1 by the holder 17, the cleaning liquid is supplied to the cleaning ring 5 and is discharged from the spout hole 11. Make it squirt. When the cleaning ring 5 is moved up and down using the knob 8, the endoscope 18 passed through the cleaning ring 5 is moved to the nozzle 1.
It is cleaned by the cleaning liquid spouted from 1. Moreover, since the cleaning liquid is uniformly jetted from the entire inner circumferential surface of the cleaning ring 5, the entire outer surface of the endoscope 18 is evenly cleaned.

In the above embodiment, if the resistance between the knob 8, the elastic membrane 10, and the guide rail 7 is reduced, if the operator releases the knob 8 after lifting the cleaning ring 5, the cleaning ring will be removed. 5 can be dropped by its own weight, and its falling speed can be adjusted by changing the elasticity of the elastic membrane 10.

Further, the cleaning device according to this invention may include a plurality of cleaning rings 5. Furthermore, the shape and structure of the holder 17 are not limited at all.

Further, the knob 8 has an elastic membrane 10 as shown in FIG.
If a flat plate-like portion 25 is formed in the portion through which the liquid passes through, a liquid-tight state between them can be ensured.

Furthermore, the shape of the jet holes 11 formed in the cleaning ring 5 is not limited in any way; for example, the shape of the jet holes 11 formed in the cleaning ring 5 is
It may be an elongated shape or a small round hole in a direction perpendicular to the circumferential direction of the inner circumferential surface of the hole.

[Effect of idea]

As described above, this invention provides a holder for suspending an endoscope on the inner surface of the upper end of the cleaning container with the interior as a housing part, and a holder that is movable up and down in the housing part and has a holder on the inner circumferential surface of the cleaning container. A cleaning ring through which an endoscope was passed and a jet hole formed on the inner circumferential surface was provided so that cleaning liquid could be supplied to the cleaning ring. Therefore, by ejecting the cleaning liquid from the ejection holes while moving the cleaning ring up and down, the outer surface of the endoscope can be thoroughly and evenly cleaned, and the cleaning operation is easy. Furthermore, since the cleaning ring is moved up and down, the overall structure is simple and the overall size of the device does not increase too much.
