Description

[Detailed description of the invention] Regarding.

In general, an endoscope cleaning device primarily cleans only the insertion section of the endoscope, and does not clean the operation section or light guide cable. however,
Recently, it has become desirable to clean the entire endoscope, and efforts are being made to put this into practical use. In the case of H, if the entire endoscope is housed in the same tank and cleaned by spraying cleaning liquid with a rotating cleaning liquid spray nozzle, the following problems arise. In other words, in order to comfortably install the entire endoscope in the same cypress, the endoscope expands widely, and as a result, the cleaning liquid is sprayed from the rotating cleaning liquid spray nozzle over the entire insertion section, light guide cable, and operation section. It becomes extremely difficult to spray the liquid evenly. 1 more
In order to place as much of the endoscope as possible in the spray area of the rotating cleaning liquid spray nozzle, it is necessary to increase the rotation diameter of the spray nozzle, resulting in an increase in the size of the entire tank. There is. In addition, if the endoscope is immersed in a disinfectant solution after cleaning to disinfect it, the large-capacity upper tank must be filled with the disinfectant solution, so a large amount of disinfectant solution is required. , which increases costs and is uneconomical.

Moreover, there are drawbacks such as a long operation time for supplying or collecting such a large amount of disinfectant.

The present invention has been developed by focusing on the above-mentioned circumstances, and its purpose is to effectively clean every corner of the insertion section, light guide cable, and operation section of an endoscope, and to also clean the cleaning tank with a computer.

Further, at rotation t#J11, an upper nozzle 28 and a lower nozzle 29 protruding in the radial horizontal direction are exposed. The upper nozzle is located above the endoscope 5 installed in the zaFi cypress 6 and sprays cleaning liquid onto the inner aperture 5 from its upper axis.

Further, the lower nozzle 2# is located below the endoscope 6 installed in the tank 6, and sprays the cleaning liquid onto the endoscope 5 from the lower side. As shown in FIG. 4, each nozzle 2&, 19 communicates with a cleaning liquid passage 31 formed by a VC in the rotary cylinder I1. The cleaning liquid passage J1 communicates with the internal space Jsi of the truncated conical portion 12 via the inflow passage 12 formed in the rotary cylinder 11 described above.

Further, the internal nitrogen space sxK of rC1 is connected to the connecting cap 14 through the connecting cap 14, and the connecting parts 35 and 35 are in communication with each other. Pressurized cleaning liquid is supplied from a cleaning liquid tank (1. not shown) using a cleaning liquid tank (not shown).

By the way, the lower nozzle 29 (composed of a nozzle shaft cylinder 36, a nozzle tip, and a nozzle 31) is fixedly attached to the rotary cylinder 1.

ζ, the upper nozzle 2# can be moved forward and backward with respect to the 1

As shown in Figure 2, the insertion part 5b is spirally wound inside and toward the light guide cable 5 side.
Light guide cable 5 or 1 is inserted into its insertion section 5.
Like 1lIK, it is spirally wound. The insertion portion Jb and the light guide cable 1 are wound and installed in the same horizontal plane on the net 41. It is supported on the shelf 41 by descending diagonally so as to be lower than the net 41. In other words, it is supported in a retracted state located lower to the side than the operating part lhF'l insertion part 5b and the light guide cable 5@.

By the way, the operating section 5& is disposed submerged in a thick, deep bay 46 as shown in FIG.

In addition, in the case of the light guide cable 5, since the insertion part jb is turned inward and the light guide cable 5 is turned outward, a part of the operating part ja is located below the light guide cable 5-.

On the other hand, a plurality of cleaning nozzles 49 . . . are fixedly installed in the bay portion 46, each facing the operating portion 5a placed on the shelf 4#. That is, this fixedly installed cleaning nozzle 41... is the above-mentioned rotating upper nozzle 2.
The cleaning liquid is sprayed toward the operation part 5a, where the cleaning liquid jetted from the lower nozzle 1 and the lower nozzle 1# does not reach sufficiently. Note that these cleaning nozzles 49... are the aforementioned water in! Connected to the cleaning liquid tank via.

In addition, as shown in Figure 3, there is a discharge port 5 at the bottom of K111g.
1 is provided, and a passage communicating with this discharge port 11 is provided with a first
The on-off solenoid valve j1 and the second on-off solenoid valve 5J are connected in parallel. The first on-off solenoid valve ss#'i is normally open, and the second on-off solenoid valve j1 is normally closed. Furthermore, the first opening/closing solenoid valve 52 is connected to the discharge outlet J4. The second opening/closing solenoid valve J1 is connected to a disinfectant tank 5j, and is connected to a disinfectant injection nozzle IIK provided on the upper wall of the tank 6 via the disinfectant tank 5j and the water turn 5-.

In addition, as shown in Fig. 2, #'i above bay part 4 is placed in the upper sweetfish tank #.
A small bay part 51 is also formed at a location other than 6, and a float switch 5# for liquid level detection is provided inside this small bay part 58.

Further, at the bottom of the 'rtpi, as shown in Figures W and 3, there is provided a raised bottom part-1 whose bottom wall is raised to avoid the passage area in which the lower nozzle j# rotates.

Next, the operation and effect of the above-mentioned cleaning device will be explained.

First, the cover 7 is opened and the endoscope 5 to be cleaned and disinfected is placed in the tank 6. At this time, the rotary tube 11 is not rotating, and both the upper and lower nozzles 18. j
9ri, stopped.

Further, since no cleaning liquid is supplied, the upper nozzle 28 does not interfere with the installation work of the endoscope 5, which is retracted by the urging force of the return spring 44.

Therefore, as shown in FIG. 2, the operation part 51 of the endoscope [5 is placed on the $48 in the tank 6, and then the insertion part 5b is placed on the net 41 in a spiral shape. Next, the light puts the ID cable 5c in a spiral manner on the outside of the insertion portion 5b in the opposite direction. In addition, since the operation part 5aFi is lowered, the light does not get in the way when winding the ID cable 5C. Then, as shown in FIG. 3, after closing the cover 7, the operation panel 3 is operated to start the cleaning operation. That is, the cleaning liquid from the cleaning liquid tank is pressurized and the cleaning liquid is sprayed onto the entire endoscope 5 through each cleaning nozzle, that is, the upper nozzle 211, the lower nozzle 19, and the nozzle 4. The upper nozzle 1# and the lower nozzle 2- spout the cleaning liquid while rotating in the tank 6 together with the rotary cylinder 11 which is driven by the drive motor jFtc.By the way, the upper nozzle 28
When the pressurized cleaning liquid is supplied into the cylinder hole 43, the piston portion 42 of the nozzle shaft cylinder 18 is pushed and moves against the restoring force of the return spring 44. Then, the piston part 42 is at a position where it crushes the mother king 4j.

At this time, by crushing the stone and the king 45, that part is held liquid-tight, so that no liquid leaks to the outside.

Furthermore, the upper nozzle 2a protrudes from the rotary cylinder 1 from this K, and its nozzle, f19, is the fixed lower nozzle 2.
If you look at this in Figure 2, it sticks out larger than the one in 9.
The upper nozzle 28 and the lower nozzle 2t have different rotation diameters at their respective nozzle tips 31°J#, and can spray the cleaning liquid in a distributed manner. Then, the upper nozzle 1# sprays from above, the lower nozzle j# sprays from below, and the other nozzles 4#... spray from the bay part 4-
Spray mainly on the operating section 1m located at .

The outer surface of the endoscope 1 is cleaned with a cleaning solution in the same manner as the endoscope 1, but the internal passages such as the forceps channel of the endoscope 5 are also cleaned once by connecting a liquid supply tube (not shown) and supplying the cleaning solution. be done.

Further, the cleaning liquid that has fallen to the bottom of the cypress 6 is collected in the river mouth s1, and is thereby discharged to the outside by the discharge bond 54 through the first (D) opening/closing solenoid valve j1.

Once this cleaning operation is complete, the disinfection process will begin if specified. That is, the first on-off solenoid valve 52 is closed, and tIX2
The on-off solenoid valve 53 operates the water bonder 5σ while remaining closed. As a result, the disinfectant in the west disinfectant tank 65 flows from the disinfectant injection nozzle 61 into the tank 6? F people are made to do it. Disinfectant is then supplied until the float switch 59 detects the liquid level.

As a result, the entire endoscope 1 is immersed in the disinfectant solution. Disinfect the area by leaving it as it is for a predetermined period of time. After the disinfection is completed, the second opening/closing '1γ' and 'magnetic valves 53 are opened to collect the disinfectant in the tank 6 into the disinfectant tank 65. This person, as previously mentioned, is rinsed with water with a uniform purification action.

In addition, when the endoscope L is taken out to the cleaning and disinfection personnel, the rotary tube 11 and the upper and lower nozzles za and x# have stopped rotating, and since there is no cleaning liquid supplied, the upper nozzle
It is pulled in and shortened by the biasing force of the Fi return spring 44. Therefore, the endoscope f#5 can be taken out easily without any hindrance.

As explained above, according to the endoscope support according to the present invention, the insertion part of the endoscope and the lie/fiber cassette are spirally wound inside and outside in the tank 5, and the operating part is moved downward. It can be placed submerged in the Therefore, the insertion section and the light guide cable can be particularly placed at the bottom of the console without the operation section getting in the way.

(For example, if the operating section is placed in a plane at the same height as the insertion section and the light guide cable, the operating section should be interposed between the insertion section and the light guide cable as shown in Figure 5 to reduce the winding force. Therefore, the allocation is that large.
Requires suis. ). Therefore, since the volume inside the cleaning tank can be reduced, the overall size of the apparatus can be reduced.

Furthermore, since the volume inside the tank is reduced, even if the endoscope is to be immersed and sterilized continuously in the cleaning ridge, the amount of disinfectant required for that purpose will be small, and costs can be reduced. Furthermore, the time required for supplying and discharging the disinfectant can be shortened.
