By the way, in Patent Document 1, when cleaning the internal pipes such as various channels of the endoscope, the internal pipes with relatively little dirt are subjected to non-circular cleaning, and the internal pipes with heavy dirt are circulated. By cleaning, the internal pipeline is cleaned according to the contamination status in the internal pipeline, but the entire endoscope cleaning considering the difference in the contamination status of the internal pipeline and the outer skin is completely touched on. It is not done.
In the circulation cleaning of Patent Document 1, after a certain amount of cleaning liquid is injected into a cleaning tank that houses and cleans the endoscope, the cleaning liquid in the cleaning tank is supplied to the second cleaning liquid via the circulation path by the cleaning liquid supply means. The internal conduit is circulated and washed by supplying the internal conduit of the endoscope, for example, the suction conduit through the supply conduit, and then discharging the internal conduit into the cleaning tank after cleaning. For this reason, the inside of the internal conduit is cleaned with a cleaning liquid that cleans the outer skin of the endoscope, and there is a problem that cleaning suitable for each of the internal conduit and the outer skin of the endoscope cannot be performed.

Also, the endoscope cleaning methods and apparatuses disclosed in Patent Documents 2 and 3 do not take into account the difference in contamination status between the internal and external parts of the endoscope.
For this reason, even in the circulation cleaning disclosed in Patent Document 2, the cleaning liquid in the cleaning tank that houses and cleans the endoscope is circulated through narrow channels such as various channels of the endoscope through the circulation path. For this reason, the inside of the capillary tube is cleaned with a cleaning solution that cleans the outer skin of the capillary tube of the endoscope, and there is a problem that cleaning suitable for the inside and outside of the capillary tube of the endoscope cannot be performed.

In addition, the various channels inside the endoscope and the material of the outer skin may be different, and there is a problem that even if cleaning is performed using the same cleaning liquid, there is a difference in cleaning.
Therefore, if each part inside and outside the endoscope is cleaned under a certain condition, there is a possibility that contaminants may remain in the endoscope depending on the part.

  As a method for solving such a problem, it is conceivable to drain the cleaning liquid every time without circulating the cleaning liquid. By doing so, the endoscope can always be cleaned with a cleaning liquid having a small amount of contaminants and a high cleaning power, so that contaminants attached to the endoscope can be more reliably removed. However, the amount of cleaning liquid used increases and the amount of drainage increases, leading to an increase in running cost.

Hereinafter, the cleaning / disinfecting process of the endoscope cleaner 10 according to the present invention will be described in detail with reference to the flowcharts shown in FIGS.
The cleaning / disinfecting process by the endoscope cleaner 10 according to the present invention includes a preliminary rinsing process with washing water, a cleaning process with cleaning liquid and cleaning particles, an air feeding process after cleaning, a disinfection process with a disinfecting liquid, and a rinsing process after disinfection. It has 5 steps.

  First, the endoscope 40 is set in the cleaning device 10. The operation unit 44, the universal cord 46 and the connector 48 of the endoscope 40 are set in the cleaning chamber 12, and the in-body insertion portion 42 of the endoscope 40 is set in the cleaning tube 14 from the communicating portion 82 of the cleaning chamber 12. Also, the air supply / liquid supply tubes 59, 61, and 63 allow the opening 62 and the air / water supply channel base 72 of the endoscope 40, the opening 60 and the supply base 74 of the endoscope 40, and the forceps hole 58 of the endoscope to be connected. The supply cap 74 is communicated with each other.

  Next, a preliminary rinsing step is performed. The preliminary rinsing step is performed in order to wash away the deposits in the channel of the endoscope 40 and the outer skin with washing water before washing. The electromagnetic valve 140 is opened, and flush water is supplied to the water supply tank 21 from the flush water supply means 22. The switching valve 156 connects the piping 182 and the piping 196, the switching valve 158 connects the piping 172 and the piping 202, and the switching valve 160 connects the piping 198 and the piping 202. In addition, solenoid valves 150, 152, and 154 are opened and the other solenoid valves remain closed.

The liquid feed pump 94 is activated, and water washing is performed from the water supply tank 21 to a plurality of endoscope channels (air supply / water supply channel 50, forceps channel 52, and suction channel 54) via the pipes 162 and 164 by the liquid supply pump 94. Water is supplied (S100). The flush water sent to the plurality of channels of the endoscope 40 removes contaminants in the channels of the endoscope 40 and is drained from the nozzle portion 56 provided at the distal end of the body insertion portion 42 of the endoscope 40. The The drained flush water is drained by the drainage pump 98 through the pipes 172, 202, and 198.
In addition, the flush water fed from the water supply tank 21 to the cleaning chamber 12 by the liquid feed pump 94 via the pipe 166 removes contaminants from the outer skin of the endoscope 40 and drains from the cleaning chamber 12 through the cleaning tube 14. The water is drained by the drainage pump 98 through the pipes 172, 202, and 198.

A convex portion 88 is provided on the inner wall of the cleaning tube 14, and the convex portion 88 has a spiral structure in the extending direction of the cleaning tube 14, so that turbulent flow is generated in the washing water in the cleaning tube 14. . The turbulent flow generated in the washing water removes contaminants on the outer skin of the endoscope 40. By doing in this way, the deposit | attachment of the outer skin of the endoscope 40 can be removed more easily.
Further, the internal insertion portion 42 of the endoscope 40 vibrates in the cleaning tube 14 due to the turbulent flow generated in the cleaning tube 14. Thereby, the deposit | attachment of the outer skin of the endoscope 40 can be removed more easily.
Furthermore, since the endoscope 40 is supported by the convex portion 88 in the cleaning tube 14, the outer skin of the endoscope 40 and the inner wall of the cleaning tube 14 are in close contact with each other, and the outer skin of the endoscope 40 touches the flush water. It is possible to prevent the formation of no area. Thereby, the deposit | attachment of the outer skin of the endoscope 40 can be removed more reliably.
The flush water that has overflowed in the cleaning chamber 12 is drained from the overflow port 78 through the drain pipe 168.
When the preliminary rinsing with the rinsing water is performed for a certain time, the supply of the rinsing water by the liquid feeding pump 94 is stopped, the rinsing water in the cleaning chamber 12 and the cleaning pipe 14 is drained, and the preliminary rinsing process is completed.

  Next, a cleaning process is performed. The cleaning process includes a channel cleaning process for cleaning the inside of the plurality of channels of the endoscope 40 and a skin cleaning process for cleaning the outer skin of the endoscope 40. In the present invention, after the inside of the channel of the endoscope 40 is washed, the outer skin of the endoscope 40 is washed. That is, after the endoscope channel is cleaned with a cleaning solution that does not clean the endoscope skin, the endoscope skin is cleaned.

First, the channel cleaning process will be described. In the channel cleaning step, the endoscope 40 is cleaned by non-circular cleaning without circulating the cleaning liquid in the channel.
The channel cleaning process is divided into a process of cleaning a severely dirty channel of the endoscope 40 and a process of cleaning a channel with relatively little dirt.
First, the channels with severe contamination, that is, the forceps channel 52 and the suction channel 54 are cleaned.

  Solenoid valves 140, 142, and 144 are opened, and the first washing liquid from the first washing liquid tank 23, the first washing liquid from the first washing liquid tank 23, and the first fine particle charging tank 24 from the first washing liquid supply tank 22. Cleaning fine particles are supplied (S102). In the water supply tank 21, the first cleaning liquid is diluted with the cleaning water, and becomes a cleaning liquid used for cleaning the channel of the endoscope 40. Further, the first cleaning particles are mixed with the cleaning liquid in the water supply tank 21 to become a cleaning liquid containing the first cleaning particles used for cleaning the channel of the endoscope 40.

The switching valves 156, 158, and 160 are held in the same state as in the preliminary rinsing process, and the electromagnetic valves 150, 152, and 154 are also held in the same state as in the preliminary rinsing process.
The liquid feed pump 94 is activated, and the first cleaning liquid is supplied from the water supply tank 21 to the endoscope channels (the air / water supply channel 50, the forceps channel 52, and the suction channel 54) via the pipes 162 and 164 ( S104). The first cleaning liquid fed into the channel of the endoscope 40 cleans the inside of the channel of the endoscope 40 and drains liquid from the nozzle portion 56 provided at the distal end of the body insertion portion 42 of the endoscope 40. Is done. The drained first cleaning liquid is drained by the drainage pump 98 through the pipes 172, 202, and 198.

Since the first cleaning liquid is drained without being circulated through the channel or outer skin of the endoscope 40, dirt such as the forceps channel 52 and the suction channel 54 of the endoscope 40 has been removed from severe places. By using the cleaning liquid containing the kimono again for cleaning, it is possible to prevent the deposit from adhering to the endoscope 40 again.
Further, since the first cleaning liquid contains the first cleaning particles, in the cleaning of the channel of the endoscope 40, physical cleaning with the cleaning particles can be performed in addition to the cleaning with the cleaning liquid. By doing in this way, the contaminant of the channel of the endoscope 40 can be removed more reliably.

The cleaning liquid that has overflowed in the cleaning chamber 12 is discharged from the overflow port 78 through the pipe 168 by the drain pump 98.
After cleaning the severely contaminated channel for a certain time (S106), the supply of the cleaning liquid by the liquid supply pump 94 is stopped, the cleaning liquid in the channel of the endoscope 40 is drained, and the severely dirty channel is cleaned. Finish.

  Next, a relatively clean channel is washed. That is, the air / water supply channel 50 is cleaned.

The solenoid valves 140, 142, and 144 are opened in the same manner as in the case of washing a severely dirty channel, and the washing water supplied from the washing water supply means 22 and the first washing liquid from the first washing liquid tank 23 and the first washing liquid are supplied to the water supply tank 21. First cleaning particles are supplied from one particle tank 24. In the water supply tank 21, the 1st washing | cleaning liquid is diluted with washing water, and becomes a washing | cleaning liquid used for washing | cleaning of the channel of the endoscope 40, and an outer_layer | skin. Further, the first cleaning fine particles are mixed with the cleaning liquid in the water supply tank 21 to become a cleaning liquid containing the cleaning fine particles used for cleaning the channel and outer skin of the endoscope 40.
The switching valve 156 communicates the piping 182 and the piping 196, the switching valve 158 communicates the piping 172 and 202, and the switching valve 160 communicates the piping 188 and 202.
Solenoid valve 154 is opened and solenoid valves 150 and 152 are closed.

  The liquid supply pump 94 is activated, and the cleaning liquid is supplied from the water supply tank 21 only to the air / water supply channel 50 of the endoscope 40 via the pipe 162 (S108). The cleaning liquid fed into the air / water supply channel 50 of the endoscope 40 cleans the inside of the air / water supply channel 50 of the endoscope 40, and a nozzle provided at the distal end of the body insertion portion 42 of the endoscope 40. The liquid is discharged from the unit 56.

In the present embodiment, the cleaning liquid used for cleaning the air / water supply channel 50 is then used for cleaning the outer skin.
The cleaning liquid discharged from the nozzle unit 56 passes through the pipes 172, 202, and 188, and after the dust is removed by the filter 100, the liquid is sent to the pipes 170 and 174 by the circulation pump 96 (S110).

The cleaning liquid in the pipe 188 is supplied with the second cleaning liquid and the second cleaning fine particles by opening the electromagnetic valves 146 and 148 (S112).
The cleaning liquid sent to the pipe 174 by the circulation pump 96 is sent into the cleaning pipe 14 from the circulating liquid supply port 86 provided in the vicinity of the communication portion 82 of the cleaning pipe 14, and the outer skin of the endoscope 40 is cleaned. Used (S114). Here, the cleaning liquid that has accumulated in the cleaning chamber 12 and overflowed is discharged from the overflow port 78 through the pipe 168 (S116). The cleaning liquid used for cleaning the outer skin of the endoscope 40 passes through the pipes 172, 202, and 188, and after the dust is removed by the filter 100, the liquid is sent again to the pipes 170 and 174 by the circulation pump 96. Further, the cleaning liquid sent to the pipe 170 by the circulation pump 96 is supplied into the cleaning chamber 12 from the circulating liquid supply port 80 and is used for cleaning the outer skin of the endoscope 40. The cleaning liquid used for cleaning the outer skin of the endoscope 40 passes through the pipes 172, 202, and 188, and after the dust is removed by the filter 100, the liquid is sent again to the pipes 170 and 174 by the circulation pump 96 (S118). ). The cleaning liquid repeats this circulation by the circulation pump 96.

  Here, a new cleaning liquid is always fed into the channel of the endoscope 40. By doing in this way, the dirt in the channel of the endoscope 40 in which the diameter of the channel is small and the dirt is difficult to be removed can be surely removed. Further, the cleaning liquid used for cleaning the air / water supply channel 50 of the endoscope 40 is reused for cleaning the outer skin of the endoscope 40 that is easily cleaned. Thus, by efficiently using the cleaning liquid, it is possible to reduce the amount of the cleaning liquid used while maintaining the cleaning performance.

  Further, the cleaning liquid and the cleaning fine particles sent into the channel of the endoscope 40 are supplied from the first cleaning liquid tank 23 and the first fine particle tank 24, and are contained in the channel of the endoscope 40. Cleaning liquid and cleaning fine particles suitable for cleaning. Also, the cleaning liquid sent from the circulating liquid supply ports 80 and 86 to the cleaning chamber 12 and the cleaning pipe 14 and the cleaning fine particles contained in the cleaning liquid are sent from the second cleaning liquid tank 26 and the second cleaning fine particle tank 28. The cleaning liquid and the cleaning fine particles are suitable for cleaning the outer skin of the endoscope 40. Accordingly, the channel of the endoscope 40 is cleaned using a cleaning liquid and cleaning particles suitable for cleaning the channel of the endoscope 40, and the outer skin of the endoscope 40 is cleaned by cleaning the outer skin of the endoscope 40. A cleaning solution and cleaning fine particles suitable for cleaning can be used. By doing in this way, a high cleaning effect can be acquired.

  Also in the cleaning step, the outer skin of the endoscope 40 can be more reliably cleaned by the convex portion 88 provided on the inner wall of the cleaning tube 14 as in the preliminary rinsing step.

  After washing for a certain time (S120), the liquid feed pump 94 and the circulation pump 96 are stopped. The pipes 198 and 202 are communicated by the switching valve 160, and the cleaning liquid in the cleaning chamber 12 and the cleaning pipe 14 is drained by the drain pump 98 (S122). When the drainage is completed, the cleaning process is terminated.

Next, air is supplied into the channel of the endoscope 40, the cleaning chamber 12, and the cleaning tube 14, and the endoscope 40 and the endoscope cleaner 10 are dried (S124).
The switching valve 156 communicates the pipes 194 and 196, the switching valve 158 communicates the pipes 172 and 202, and the switching valve 160 communicates the pipes 198 and 202. In addition, the solenoid valves 150, 152, and 154 are opened.

The gas cylinder 32 feeds a drying gas while maintaining a constant pressure by the pressure reducing valve 90 and the pressure sensor 92. The drying gas that has passed through the pipes 162 and 164 dries in the channel of the endoscope 40 (the air / water supply channel 50, the forceps channel 52, and the suction channel 54). Further, the drying gas that has passed through the pipe 166 is sent from the supply port 76 to the cleaning chamber 12 and the cleaning tube 14 to dry the cleaning chamber 12 and the cleaning tube 14.
Again, since the endoscope 40 is supported by the convex portion 88 in the cleaning tube 14, the outer skin of the endoscope 40 and the inner wall of the cleaning tube 14 are in contact with each other, and the outer skin of the endoscope 40 does not touch the drying gas. A region can be prevented from being formed. Thereby, the endoscope 40 can be more reliably dried.

  By performing the air supply process, not only can the endoscope 40 be dried, but also the cleaning chamber 12 and the cleaning tube 14 can be dried. By doing so, it is possible to prevent the remaining cleaning liquid from being mixed with the disinfecting liquid used in the next disinfecting step and the sanitizing performance of the disinfecting liquid from being deteriorated.

After supplying air for a certain time (S126), the air supply is stopped.
When the air supply ends, the cleaning process ends.

Next, a disinfection process is performed.
The pipes 190 and 196 are communicated by the switching valve 156. Further, the pipes 172 and 192 are communicated by the switching valve 158. Further, the switching valves 160 allow the pipes 198 and 202 to communicate with each other. As for the solenoid valve, the solenoid valves 150 and 152 are opened, and the subsequent solenoid valves are closed.

The liquid feeding pump 94 is activated, and the disinfecting liquid is fed to the channels of the endoscope 40 (the air / water feeding channel 50, the forceps channel 52, and the suction channel 54) and the cleaning chamber 12.
Since the electromagnetic valve 154 is closed, the disinfectant solution accumulates in the cleaning tube 14 and the cleaning chamber 12 and immerses the endoscope 40. Thereby, the channel of the endoscope 40 and the outer skin of the endoscope 40 are sterilized.

  After immersion and disinfection of the endoscope 40 for a certain time, the electromagnetic valve 154 is opened, and the disinfecting liquid in the cleaning chamber 12 and the cleaning pipe 14 is collected from the pipe 192 to the disinfecting liquid tank 30.

  Finally, a rinsing step is performed. In the rinsing process, rinsing of the washing chamber 12, the washing tube 14, and the endoscope 40 with washing water is performed. The electromagnetic valve 140 is opened, and flush water is supplied to the water supply tank 21 from the flush water supply means 22. The switching valve 156 connects the piping 182 and the piping 196, the switching valve 158 connects the piping 172 and the piping 202, and the switching valve 160 connects the piping 198 and the piping 202. In addition, solenoid valves 150, 152, and 154 are opened and the other solenoid valves remain closed.

The liquid feed pump 94 is activated, and water washing is performed from the water supply tank 21 to a plurality of endoscope channels (air supply / water supply channel 50, forceps channel 52, and suction channel 54) via the pipes 162 and 164 by the liquid supply pump 94. Water is supplied. The flush water sent to the plurality of channels of the endoscope 40 is rinsed through the channels of the endoscope 40 and drained from the nozzle portion 56 provided at the distal end of the body insertion portion 42 of the endoscope 40. The drained flush water is drained by the drainage pump 82 via the pipes 172, 202, and 198.
Further, the flush water fed from the water supply tank 21 to the washing chamber 12 by the liquid feed pump 94 via the pipe 166 is rinsed from the outer skin of the endoscope 40 and is drained from the washing chamber 12 through the washing pipe 14 to the piping. Drained by a drain pump 82 through 172, 202, and 198. Above, a rinse process is complete | finished.
