Description

Description: [Industrial application] The present invention relates to an endoscope disinfection device for disinfecting an endoscope.

[Prior Art] A general endoscope cleaning / disinfecting apparatus known in Japanese Patent Laid-Open No. 60-90531 sprays a cleaning liquid from a nozzle onto the outer surface of an endoscope installed in the cleaning tank. At the same time, the cleaning liquid is fed into the duct inside the endoscope to clean the inner and outer surfaces of the endoscope. After this cleaning, fill the cleaning tank with antiseptic solution, dip the endoscope in the antiseptic solution, and send the antiseptic solution to the duct inside the endoscope to disinfect the inner and outer surfaces of the endoscope. ing. After this disinfection, tap water is used to perform the same operation as the above-described cleaning operation to perform rinsing. Then, finally, air is sent into the conduit of the endoscope to remove the residual water in the conduit.

[Problems to be Solved by the Invention] However, when the endoscope is cleaned and disinfected by the above-described conventional cleaning and disinfecting apparatus, the cleaning, disinfecting, rinsing, and drying steps are carried out in series. For,
It took a lot of time and it was difficult to process in a short time.

Therefore, recently, attention has been paid to the fact that hydrogen peroxide gas (VPHP) has an extremely high bactericidal effect, and a cleaning / disinfecting apparatus using this has been considered (see the application for Japanese Patent Application No. 1-192843). ). According to this, after the cleaning and drying process, hydrogen peroxide gas is sent into the cleaning tank in which the endoscope is installed,
By leaving it for the time required for disinfection, the outer surface of the endoscope and the inside of the duct were disinfected.

By the way, the outer surface of the endoscope is relatively effectively disinfected because hydrogen peroxide gas is fed into the cleaning tank in which the endoscope is installed and left standing for the time required for the disinfection. . However, if you just leave it alone,
It is difficult for the endoscope to enter the duct.

In general, the conduit of an endoscope is generally thin, and it is difficult for hydrogen peroxide gas to naturally flow to every corner, so that sufficient disinfection cannot be performed.

In addition, when the temperature of the endoscope is lower than the temperature in the tank, hydrogen peroxide gas is liquefied in the pipeline and further impedes the inflow of hydrogen peroxide gas, which lowers the disinfection level. There are drawbacks.

Further, it is conceivable that the hydrogen peroxide gas is forcibly sent by the air supply tube by the air pump, but in this case, dirt such as dust and oil contained in the device such as the air pump may be sent at the same time. In order to prevent this, purification means such as a filter for removing them is required, and this maintenance is troublesome.

The present invention has been made in view of the above problems, and an object thereof is to provide an endoscope disinfection device capable of rapidly and surely disinfecting the inside of a conduit of an endoscope with hydrogen peroxide gas. To provide.

[Means and Actions for Solving the Problems] In order to solve the above problems, the present invention provides a disinfecting apparatus for an endoscope, which disposes the endoscope in a tank and disinfects the endoscope. A gas generating means, a hydrogen peroxide gas supplying means for supplying the hydrogen peroxide gas generated by the hydrogen peroxide gas generating means to the tank side, a suction means, and a pipe line of the endoscope in the suction means. When the hydrogen peroxide gas is supplied to the tank using the connecting means for connecting and the hydrogen peroxide gas supply means to disinfect the endoscope, the suction means is operated to operate the conduit of the endoscope. A control means for drawing in hydrogen peroxide gas is provided therein.

Therefore, when disinfecting the endoscope installed in the tank, first, hydrogen peroxide gas is supplied from the hydrogen peroxide gas supply means into the tank, and the suction means is used to connect the endoscope to the conduit of the endoscope. The hydrogen oxide gas is drawn in, and the hydrogen peroxide gas is made to fully flow inside and outside the endoscope. This ensures that the inside and outside of the endoscope are sterilized by the hydrogen peroxide gas.

The other end of the supply / discharge tube 53 is detachably connected to the connection mouthpiece 7 provided on the side wall of the cleaning chamber 4.

Next, the operation of the endoscope cleaning / disinfecting apparatus 1 in the configuration of this embodiment will be described. In the endoscope cleaning / disinfecting apparatus 1 of this embodiment, there are a normal cleaning / disinfecting step performed at the end of the day and the like, and a cleaning / disinfecting step performed in a short time between cases such as group examination. Then, each of these steps performs the operation corresponding to the one selected by the control means (not shown).

First, the operation of the normal cleaning / disinfecting step will be described with reference to the time chart shown in FIG. This is divided into washing, drying and disinfecting steps.

First, the endoscope 3 is previously installed in the cleaning chamber 4 of the cleaning tank 2, and as shown in FIG. 2, the connector 52 is connected to the air / water supply cylinder 44 and the suction cylinder 45 from which the respective switching valve bodies are removed. Hang on to. The supply / discharge tube 53 communicating with the connector 52 is connected to the connection mouthpiece 7 provided on the side wall of the cleaning chamber 4.

After the preparation is completed, each process is started.
First, in the cleaning process, first, the water supply valve 35 of the water supply pipe system 18 is opened to inject tap water into the tank 5. After that, the circulation pump 21 of the circulation line system 15 operates to supply the cleaning liquid in the tank 5 to the base 7 and the injection nozzle 8. The cleaning liquid supplied to the mouthpiece 7 side is fed into the conduits 41, 42, 43 of the endoscope 3 as a disinfecting object to be cleaned, which is previously installed in the cleaning chamber 4 of the cleaning tank 2.

The cleaning liquid supplied to the spray nozzle 8 is sprayed on the outer surface of the endoscope 3. The wash water that has flowed down into the tank 5 is circulated again through the circulation line system 15, and thus the inner and outer surfaces of the endoscope 3 continue to be washed. Simultaneously with the start of this cleaning operation, the heater 37 in the tank 5 generates heat to heat the circulating cleaning water. Therefore, the cleaning action is enhanced.

In the latter half of the cleaning process (water removal process), the drainage pump 23 starts operating and drains the cleaning water accumulated in the tank 5 of the cleaning tank 2 through the drainage pipe system 16. Further, the first switching valve 27 is switched to the supply / discharge pipe line 28 side and the second switching valve 32 is switched to the air pump 34 side, and at the same time, the air pump 33 is actuated to operate from the base 7 to the supply / discharge tube 53 and the connector. Each conduit of the endoscope 3 through 52
Air is sent to 41, 42, 43 to drain the water in each of the pipelines 41, 42, 43.

This draining operation continues in the next drying process. heater
37 also continues during the drying process.

Further, in the drying process, the exhaust fan 9 in the exhaust pipe system 11 is operated and the electromagnetic exhaust valve 12 is switched to the exhaust pipe line 11a. Therefore, the gas in the cleaning chamber 4 is discharged to the outside through the exhaust pipe system 11.

Further, the air in the cleaning tank 2 is heated by the heater 37 to increase its temperature and becomes in a dry state, and this air dries the outer surface of the endoscope 3. Since this air circulates in the pipeline of the endoscope 3, the moisture in the pipelines 41, 42, 43 also evaporates and dries.

When sufficient drying is performed as described above, a disinfection process using hydrogen peroxide gas is performed.

That is, the electromagnetic line switching valve 29 is switched to the hydrogen peroxide gas generating unit 25 side and the hydrogen peroxide liquid cartridge 30 is switched.
Connect. As a result, for example, 30% hydrogen peroxide solution is sent from the hydrogen peroxide solution cartridge 30 to the hydrogen peroxide gas generation unit 25. Hydrogen peroxide gas generation unit
At 25, the 30% hydrogen peroxide solution is heated and vaporized to generate hydrogen peroxide gas. This hydrogen peroxide gas is sent into the cleaning chamber 4 of the cleaning tank 2 through the hydrogen peroxide gas supply pipe system 17. The check valve 26 prevents the backflow of the cleaning liquid, vapor, etc. from the cleaning tank 2 side and prevents the hydrogen peroxide gas generating unit 25 from being damaged.

In this way, the cleaning tank 2 is filled with hydrogen peroxide gas for a certain period of time.
When the cleaning chamber 4 is filled with a sufficient amount of hydrogen peroxide gas, the first pipe switching valve 27 and the second pipe switching valve 32 are switched to the vacuum pump 34 side. . Then, by operating the vacuum pump 34, the conduits 41, 42, 43 of the endoscope 3 are sucked through the supply / discharge conduit 28, the connection mouthpiece 7, the supply / discharge tube 53, and the connector 52. As a result, the pressure in the pipes 41, 42, 43 becomes negative with respect to the pressure in the cleaning chamber 4, so that the hydrogen peroxide gas in the cleaning chamber 4 is sucked from the openings of the pipes 41, 42, 43. To do. That is, the air supply conduit 41 sucks from the nozzle 46 and the air supply cap 47. Also,
The air supply line 42 sucks from a nozzle 46 and a water supply base 48. Then, it passes through the air / water supply cylinder 44 and flows out to the supply / discharge tube 53 side. On the other hand, the suction conduit 43 sucks from the suction port 49, the suction mouthpiece 50, and the forceps insertion port 51. And the suction cylinder 45
Through the supply / discharge tube 53 side.

In this manner, the hydrogen peroxide gas is filled in each of the pipelines 41, 42, 43 and is sufficiently circulated. In this state, the generation operation of the hydrogen peroxide gas generation unit 25 and the suction operation of the vacuum pump 34 are stopped.

Then, the inside of each of the pipelines 41, 42, 43 and the cylinders 44, 45 is maintained by keeping the state in which each of the pipelines 41, 42, 43 is filled with hydrogen peroxide gas and fully circulated for a necessary time. Can be disinfected. Of course, at the same time, the outer surface of the endoscope 3 is disinfected.

Before starting this disinfection process, the following is performed. The electromagnetic exhaust valve 12 is switched to the hydrogen peroxide gas processing unit 13 side, and the exhaust pipe line system 11 is connected to the hydrogen peroxide gas processing unit 13. This prevents the hydrogen peroxide gas from being discharged to the outside of the cleaning / disinfecting apparatus 1 without being treated. Then, when this disinfection process is completed, the exhaust fan 9 is operated to send the hydrogen peroxide gas in the cleaning tank 2 to the hydrogen peroxide gas processing unit 13. Furthermore, the first line switching valve
27 and the second conduit switching valve 32 are switched to the vacuum pump 34 side. Then, by operating the vacuum pump 34, the hydrogen peroxide gas remaining in each of the conduits 41, 42, 43 of the endoscope 3 is sent to the hydrogen peroxide gas processing unit 13.

In this way, the hydrogen peroxide gas is appropriately decomposed into H ₂ O or O ₂ by the hydrogen peroxide gas processing unit 13 to render it harmless, and then discharged to the outside.

Since hydrogen peroxide gas has a low concentration of about 0.5 ppm,
A small amount remains in the endoscope 3, and since it decomposes naturally, there is no concern about residual toxicity.

Next, the action of the cleaning / disinfecting process performed in a short time between cases in, for example, a mass examination will be described with reference to the time chart shown in FIG. This is divided into cleaning, disinfecting and rinsing steps.

The washing process is performed in the same manner as described above. After this cleaning process, a disinfection process is performed.

That is, the water supply valve 35 is opened again and the tank 5 of the cleaning tank 2 is
While tap water is injected into the tank 5, the pipe switching valve 29 is switched to the hydrogen peroxide liquid supply pipe 31 side to directly supply the hydrogen peroxide liquid into the tank 5 of the cleaning tank 2. Since the hydrogen peroxide solution stored in the hydrogen peroxide solution cartridge 30 is usually a diluted solution of about 30%, the tank 5 of the cleaning tank 2 is
Is diluted with tap water from the above water supply within 3% -10
The concentration becomes about%, and is stored in the tank 5.

After that, the open / close switching valve 22 is opened to open the first pipeline switching valve.
27 is switched so that the pipe line 15a is connected to the base 7 of the cleaning chamber 4, and the circulation pump 21 of the circulation pipe line system 15 is operated. As a result, the hydrogen peroxide solution in the tank 5 is separately supplied to the two pipe lines 15a and 15b of the circulation pipe system 15, and is supplied to the base 7 and the injection nozzle 8. Then, the liquid is sent from the mouthpiece 7 into the respective conduits 41, 42, 43 of the endoscope 3, and jetted from the jet nozzle 8 to the outer surface of the endoscope 3. The low concentration hydrogen oxide liquid disinfects the inner and outer surfaces of the endoscope 3. At this time, even if the water adhering to the endoscope 3 in the cleaning process is mixed into the disinfecting solution, the concentration is slightly decreased and there is no problem. Further, it is possible to set the density to a slightly higher level in advance in anticipation of a decrease in density. As described above, since the inside and outside of the endoscope 3 is sterilized with the hydrogen peroxide solution, the disinfection effect is sufficiently ensured unlike the disinfection with the hydrogen peroxide gas.

At the end of this disinfection process, the drainage pump 23
Is activated and the hydrogen peroxide solution in the tank 5 is drained. At the same time, the first switching valve 27 is switched to the supply / discharge pipe line 28 side, the second switching valve 32 is switched to the air pump 34 side, and further, the air pump 33 is operated to operate the mouthpiece 7 to supply / discharge tube 53. And air is sent into each of the conduits 41, 42, 43 of the endoscope 3 through the connector 52. Then, the water is drained from each of the conduits 41, 42, 43 of the endoscope 3.

Then, when the disinfection process is completed, a rinsing process is performed. That is, the water supply valve 35 is reopened to inject tap water into the tank 5 of the cleaning tank 2, and the circulation pump 21 of the circulation pipeline system 15 is operated so that the tap water in the tank 5 is discharged through the circulation pipeline system 15. It is supplied to the base 7 and the injection nozzle 8.
Then, water is supplied from the base 7 into the ducts 41, 42, 43 of the endoscope 3, and sprayed from the jet nozzle 8 to the outer surface of the endoscope 3. As a result, the inner and outer surfaces of the endoscope 3 are rinsed. Further, after this, the first switching valve 27 switches to the supply / discharge pipe line 28, and the second switching valve 32 switches to the air pump.
After switching to the 34 side, the air pump 33 is further actuated to send air from the mouthpiece 7 to the respective conduits 41, 42, 43 of the endoscope 3 through the supply / discharge tube 53 and the connector 52. Then, the tap water remaining in each of the conduits 41, 42, 43 of the endoscope 3 is discharged.

In addition, according to the above configuration, a disinfection process using a low-concentration hydrogen peroxide solution can be selected in addition to the normal disinfection process using hydrogen peroxide gas, so that it can be dealt with even in a short time between cases.

Further, in the disinfection process using low concentration hydrogen peroxide, the hydrogen peroxide solution cartridge 30 used in the disinfection process using hydrogen peroxide gas can be used as the same source material.
Moreover, in each of the different disinfection steps described above, almost the same pipe line, pump, etc. can be used, so that the structure can be simplified.

In the above embodiment, the jetting action of jetting the hydrogen peroxide solution from the jetting nozzle 8 to the outer surface of the endoscope 3 may be performed also in the cleaning step. If you do this,
The oxidizing action of hydrogen peroxide solution can be used to remove dirt,
The cleaning effect can be enhanced. In this case, the steps of washing with water → washing with hydrogen peroxide → drying → washing with hydrogen peroxide gas can be considered.

Further, although there is a pipe line system of the endoscope 3 as shown in FIG. 2, other pipe line systems having other configurations, for example, a connecting portion of the liquid feeding pipe line to the endoscope are also provided. The same can be done by changing the.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, a concentration detection sensor 60 is provided as a means for detecting the concentration of hydrogen peroxide gas in the cleaning chamber 4 of the cleaning tank 2 in the configuration of the first embodiment.

Then, in the disinfection step, when the carbon peroxide gas is sent to the cleaning chamber 4, the concentration detection sensor 60 detects the concentration of hydrogen peroxide gas in the cleaning chamber 4, and when the concentration reaches a predetermined level that allows sufficient disinfection. First line switching valve 27
And the second conduit switching valve 32 is switched so as to communicate with the vacuum pump 34 side. And vacuum pump
By operating 34, the pipe lines 41, 42, 43 of the endoscope 3 are sucked, and the hydrogen peroxide gas is drawn into the pipe lines 41, 42, 43 and sucked, and at the same time, outside the cleaning chamber 4. Discharge. After that, when the predetermined concentration is reached, the operations of the hydrogen peroxide gas generation unit 25 and the vacuum pump 34 are stopped,
Leave it in that state for a while. After this, when the concentration of hydrogen peroxide gas in the cleaning chamber 4 decreases, the concentration detection sensor
60 detects this, operates the hydrogen peroxide gas generation unit 25 again, and repeats the above operation to increase the concentration of the hydrogen peroxide gas in the cleaning chamber 4 to a predetermined disinfectable concentration.

Therefore, in this embodiment, the concentration detection sensor 60
Detects the concentration of hydrogen peroxide gas in the cleaning chamber 4 and determines the timing of drawing the hydrogen peroxide gas into each of the conduits 41, 42, 43 of the endoscope 3. Even if the hydrogen peroxide gas concentration in the cleaning chamber 4 is not uniformly increased due to changes in the hydrogen oxide gas generation efficiency, the concentration can be increased to an appropriate concentration. And, a stable disinfection effect is always obtained.

Further, since the hydrogen peroxide gas concentration in the cleaning tank 2 can always be kept within a certain range, effective disinfection can be performed for a long period of time.

In addition, when the concentration of hydrogen peroxide gas in the cleaning chamber 4 is increased to a predetermined disinfectable concentration, the vacuum pump
In order to operate 34, the concentration of hydrogen peroxide gas in the cleaning chamber 4 and each of the pipelines 41, 42, 43 is secured. Therefore, when the vacuum pump 34 is operated in a low concentration state, the concentration cannot be increased to the concentration required for sterilization, and sufficient sterilization may not be possible, which can be solved by the above action.

The other operational effects are the same as those in the first embodiment.

The present invention is not limited to the above-mentioned configurations, and various modifications can be made without departing from the scope of the invention. For example, as the hydrogen peroxide gas generation unit, its original material may be used instead of the hydrogen peroxide liquid cartridge.

[Effects of the Invention] As described above, according to the present invention, hydrogen peroxide gas can be generally circulated to every corner of a narrow and long endoscope conduit, and sterilization is sufficiently and surely performed at every corner. be able to.

Further, when the temperature of the endoscope is lower than the temperature in the tank, the hydrogen peroxide gas is liquefied in the pipe line, which tends to further hinder the circulation of the hydrogen peroxide gas. Also in this case, hydrogen peroxide gas can be sufficiently circulated to surely disinfect.

Further, since the hydrogen peroxide gas in the tank is sucked by the suction means, it is included in the device such as the air pump unlike the case where the hydrogen peroxide gas is forcibly sent through the air feeding tube etc. by the external air pump. It is possible to prevent dirt such as dust and oil from being fed into the conduit of the endoscope, and therefore, a purifying means such as a filter for removing them is unnecessary and maintenance thereof is also unnecessary.

As described above, according to the present invention, the outer surface of the endoscope and the inside of the duct can be quickly and surely disinfected by the hydrogen peroxide gas.
