Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for cleaning and disinfecting an endoscope after use.

[Conventional technology]

Endoscopes used in the medical field must be cleaned and disinfected after each use to prevent infection. For this reason, cleaning and disinfecting equipment is used.

In conventional cleaning and disinfecting equipment,
As shown in Publication No. 83602, an object to be cleaned, such as a used endoscope or an insertion aid, is placed in a cleaning layer, and the object to be cleaned is sprayed with cleaning liquid from a spray nozzle, for example. Wash away dirt etc. adhering to the object, and then, depending on the case, supply rinsing water to the cleaning layer for rinsing, then supply disinfectant to the cleaning layer to fill the cleaning layer with disinfectant, thereby removing the contaminated material. Disinfect the items by soaking them in a disinfectant solution,
After this, the object to be cleaned is dried by blowing warm air.

In order to conserve expensive disinfectant, some of these cleaning and disinfecting apparatuses employ a system in which the disinfectant used for disinfection is collected in a disinfectant tank and reused.

However, when the disinfectant is used repeatedly, there is a risk that water droplets adhering to the cleaning layer, the endoscope, etc. may mix into the disinfectant, causing the disinfectant to become gradually diluted. Therefore, it is necessary to periodically test the concentration of the disinfectant to determine whether the disinfectant ability has been lost due to a decrease in the concentration.

As a method for testing the concentration of a disinfectant solution, a method of soaking a test paper with the disinfectant solution and examining the color change is a commonly known and inexpensive method.

[The problem that the idea aims to solve]

However, in conventional cleaning/disinfection equipment, there is no consideration given to testing the concentration of the disinfectant solution.For example, a method is adopted in which a small amount of disinfectant solution is extracted from the drain of the disinfectant tank and tested. There was a problem with opening and closing, which required troublesome work.

The present invention aims to provide an endoscope washer/disinfector that can easily test the concentration of disinfectant.

[Means to solve the problem]

The present invention is characterized in that the device main body is provided with a disinfectant liquid check window that communicates with the disinfectant liquid line inside the device main body and opens to the outside of the device main body.

[Effect]

According to this invention, by inserting a test strip into the disinfectant fluid line through the disinfectant fluid check window, the disinfectant solution can easily come into contact with the test strip, eliminating the need for troublesome efforts such as opening and closing the drain inside the device body. becomes.

〔Example〕

The present invention will be described below based on a first embodiment shown in FIGS. 1 and 2.

In the figure, 1 is a substantially box-shaped cleaning and disinfecting device main body, and inside this device main body 1 there is a cleaning layer 2 on the top.
The space above the cleaning layer 2 is covered by an opening/closing cover 3 provided on the main body 1 of the apparatus.

At the center of the cleaning layer 2, a rotary body 6 is installed which has injection nozzles 4 and 5 at its upper and lower parts, respectively, and this rotary body 6 is rotated by a motor 7.

A mounting table 8 on which an endoscope A, which is an object to be cleaned, is placed is spirally provided around the rotating body 6. Cleaning water is sprayed all over A.

A water supply tank 10 and a disinfectant tank 15 are provided in the lower part of the cleaning and disinfecting device main body 1.

A water faucet 12 is connected to the water tank 10 via a solenoid valve 11, and tap water supplied from the water faucet 12, that is, washing water, is stored in the water tank 10. The water supply tank 10 is connected to a water supply pump 13, and this water supply pump 13 is connected to the injection nozzles 4, 5 through a water supply pipe 14 inserted through the interior of the rotating body 6. The cleaning water stored in the water supply tank 10 is pressurized by the water supply pump 13, and the water is sent to the injection nozzles 4, 5.
The liquid is sprayed onto the mounting table 8 from there.

A disinfectant solution set to a predetermined concentration is stored in the disinfectant tank 15, and this disinfectant solution is connected to a disinfectant pump 16, and this disinfectant pump 16 is used for cleaning via a disinfectant solution supply pipe 17. It is connected to a disinfectant solution inlet 18 provided in layer 2. Therefore, the disinfectant in the disinfectant tank 15 is pressurized by the disinfectant pump 16 and supplied to the cleaning layer 2 from the disinfectant inlet 18.

A drain port 19 is formed at the bottom of the cleaning layer 2, and the drain port 19 is connected to a three-way switching valve 20. One port of the three-way switching valve 20 is connected to the disinfectant tank 15 through a recovery pipe 21.
The other port of the three-way switching valve 20 is connected to a drain pump 23 via a drain pipe 22. Drain pump 23 is connected to waste pipe 24. Therefore, when the three-way switching valve 20 is switched to one side, the disinfectant solution accumulated in the cleaning layer 2 is collected in the disinfectant tank 15, and when the three-way switch valve 20 is switched to the other side, it is discharged from the drain pump 23 to the outside through the waste pipe 24. It is now being discharged.

A disinfectant solution check tank 25 is communicated with the disinfectant solution tank 15, and a check pipe 26 is connected to this disinfectant solution check tank 25. The check pipe 26 passes through the apparatus main body 1 and is led out to the outside, and a check window 27 opened at the end of the check pipe 26 is opened and closed by an opening/closing lid 28 shown in FIG. The check window 27 is located at a higher level than the disinfectant liquid level in the disinfectant tank 15, so that the disinfectant does not overflow from the check window 27 even if the opening/closing lid 28 is opened.

A controller 30 is installed at the front of the apparatus main body 1, and an operation panel 31 connected to the controller 30 is provided at the upper surface of the front. By operating the operation panel 31 and setting the cleaning and disinfection time etc. in the controller 30, cleaning and disinfection will be automatically performed according to this program.

The operation of an embodiment of such a configuration will be explained.

The opening/closing cover 3 is opened, and the used endoscope A is accommodated in the cleaning layer 2 and placed on the mounting table 8.

In this state, operate the operation panel 31 to turn on the power.

The device then starts operating, but first begins the cleaning process. In other words, when the power is turned on, the solenoid valve 11
is opened, tap water, ie, wash water, is supplied from the water faucet 12 to the water supply tank 10, and the water supply pump 13 is started, and the wash water is force-fed from the water supply tank 10 to the injection nozzles 4, 5. At this time, the motor 7 is activated to rotate the rotating body 6 and rotate the injection nozzles 4 and 5. Further, the three-way switching valve 20 is connected to the drain pipe 22 side, and the drain pump 23 is also activated.

Therefore, the cleaning water supplied from the water faucet 12 passes through the injection nozzles 4 and 5 to the endoscope A on the mounting table 8.
Therefore, dirt such as blood and mucus adhering to the endoscope A is washed away.

The cleaning water injected into the endoscope A from the injection nozzles 4 and 5 is guided from a drain port 19 opened at the bottom of the cleaning layer 2 to a drain pipe 22 via a three-way switching valve 20, and then to a waste pipe 22 by a drain pump 23. 24 to the outside.

Cleaning is performed by performing such operation for a predetermined period of time.

Note that a detergent may be used during this cleaning step. In this case, the water supply tank 10 has a water faucet 12.
A predetermined amount of washing water is introduced and stored, and a detergent is mixed into this washing water to create a detergent solution. This detergent liquid is injected from the injection nozzles 4 and 5 onto the endoscope A in the same way as the above-mentioned cleaning action, thereby washing away dirt from the endoscope A. Thereafter, cleaning water from the tap 12 is sprayed onto the endoscope A from the spray nozzles 4 and 5, thereby rinsing the endoscope A.

When such a cleaning process is completed, the solenoid valve 11
is closed, the water supply pump 13 is stopped, the motor 7 is also stopped, and the drain pump 23 is also stopped.

Next, we enter the disinfection process, but in this disinfection process,
The three-way switching valve 20 is switched and connected to the recovery pipe 21, and the disinfectant pump 16 is started.

Then, the disinfectant pump 16 moves to the disinfectant tank 15.
The disinfectant in the cleaning layer 2 is sent to the disinfectant inlet 18.
supply to

As a result, a predetermined amount of disinfectant is supplied into the cleaning layer 2, and the endoscope A placed on the mounting table 2 is immersed in the disinfectant. For this reason, sterilization of endoscope A,
Disinfection is done.

During such disinfection, the disinfectant solution in the cleaning layer 2 is returned to the disinfectant tank 15 from the drain port 19 via the three-way switching valve 20 and the recovery pipe 21, so that the disinfectant solution flows between the disinfectant tank 15 and the cleaning layer. It is circulated between 2 and 2.

After disinfection has been carried out for a predetermined period of time, the disinfectant pump 16 is stopped, and all of the disinfectant in the cleaning layer 2 is collected into the disinfectant tank 15 through the drain port 19 and the three-way switching valve 20.

In this way, cleaning and disinfection are performed.

Note that at the end of each cleaning and disinfection process, the cleaning layer 2 may be evacuated using a fan or the like, or the endoscope A may be dried by blowing in warm air.

In such a cleaning and disinfecting device, the disinfectant is circulated between the disinfectant tank 15 and the cleaning layer 2 and used repeatedly. However, when the disinfectant is used repeatedly, water droplets adhering to the cleaning layer 2, the endoscope A, etc. mix into the disinfectant, and the disinfectant becomes gradually diluted.

Therefore, we regularly test the concentration of disinfectant,
It is necessary to investigate whether disinfection ability is lost due to a decrease in concentration.

In this embodiment, a check window 27 is formed in addition to the device main body 1, and this check window 27 communicates with the disinfectant tank 15 via the check pipe 26 and the disinfectant check tank 25. By opening 27 and inserting the test paper B from here, the disinfectant can be applied to the test paper B. When a disinfectant is applied to the test paper B, the concentration of the disinfectant can be determined by the degree of color change, and therefore the disinfectant ability can be tested.

In this case, since the check window 27 is led out to the outside of the device main body 1, the inspection work is easy.
It doesn't take much time.

Furthermore, if the concentration of the disinfectant solution is found to be low based on the above inspection, the concentration can be increased by injecting a concentrated disinfectant solution source through the check window 27.

Note that in the normal case when the disinfectant is not tested, the check window 27 is closed by the opening/closing lid 28.

FIG. 3 shows another embodiment of the invention.

In the case of this embodiment, the disinfectant tank 15 is installed close to the side wall of the device main body 1, the check window 27 is provided directly on the disinfectant tank 15, and the check window 27 is opened in the side wall of the device main body 1. The device is opened and closed by an opening/closing door 28 formed on the main body 1 of the device.

In the case of such a configuration, a special disinfectant liquid check tank 25 is not required, and the structure is simplified.

[Effect of idea]

As explained above, according to the present invention, if a test strip is inserted into the disinfectant pipe through the disinfectant check window,
The disinfectant can be easily brought into contact with the test strip,
Therefore, there is no need for troublesome efforts such as opening and closing the drain in the main body of the device, so that the concentration of the disinfectant can be easily tested.
