Further, the control unit 37 of the endoscope cleaning device is provided with an operation panel 37a as identification information input means operated by a user, and the user checks the model of the endoscope 10 to be cleaned and operates the operation panel 37a. This allows the endoscope cleaning device to recognize the model of the endoscope 1.
[0034]
Next, the operation of the endoscope cleaning device configured as described above will be described. First, the power of the endoscope cleaning device is turned on, and the endoscope 10 is set in the cleaning tank 11. At this time, the user checks the model of the endoscope 1 and operates the operation panel 37a to make the control unit 37 of the endoscope cleaning device recognize the endoscope 10 to be cleaned / disinfected. If there is a means for automatically recognizing the endoscope 10 set in the endoscope cleaning device, the type of the endoscope 10 to be cleaned / disinfected is recognized thereby.
[0035]
Next, when a cleaning brush set button on the operation panel 37a is pressed, the motor is driven by a signal from the control unit 37, and the pair of rollers 23 is rotated. Then, the user inserts the end side of the insertion portion 19 of the cleaning brush 21 into the brush storage channel 15 from the connector 29. When the distal end of the insertion portion 19 of the cleaning brush 21 is sandwiched between the pair of rotating rollers 23, the cleaning brush 21 is drawn into the brush storage conduit 15.
[0036]
At this time, the number of magnets 19a installed in the insertion portion 19 of the cleaning brush 21 through which the magnetic sensor 28 passes is detected. Since the motor driving the roller 23 is controlled through the control unit 37 while comparing the information stored in advance in the storage means of the control unit 37 of the apparatus with the detected number of magnets 19a of the cleaning brush 21, the cleaning brush is controlled. 21 is not stored in the brush storage conduit 15 more than necessary.
[0037]
Next, when the cleaning start button on the operation panel 37a is pressed, the cleaning process is started. The cleaning liquid is supplied to the cleaning tank 11 from a water tap through a filter. After a certain amount is injected into the cleaning tank 11, the pump 13 is operated, and the cleaning liquid is washed while the cleaning liquid is injected from the brush housing pipe 15 into the endoscope pipe 31 via the connecting pipe 30. At this time, the pair of rollers 23 rotates in the direction opposite to the direction in which the cleaning brush 21 is drawn into the brush storage conduit 15, and the cleaning brush 21 is inserted into the endoscope conduit 31.
[0038]
The magnet 19a installed in the insertion portion 19 of the cleaning brush 21 passes through the magnetic sensor housing 18 via the roller housing 17. At this time, the magnetic sensor 28 detects the magnet 19a provided on the cleaning brush 21 every time the magnet 19a passes. The controller 37 of the endoscope cleaning device can recognize how many magnets 19a have passed the magnetic sensor 28.
[0039]
Here, the endoscope cleaning device controls the driving of the motor that rotates the roller 23 while comparing the information stored in advance with the number of magnets 19a detected by the model of the endoscope 10 that has been input. When the required number of magnets 19a have passed by the endoscope 10 recognized at the time of the initial setting, the motor is automatically stopped, and the rotation of the roller 23 is stopped. Thereafter, the roller 23 is rotated in the reverse direction, the cleaning brush 21 is removed from the endoscope conduit 31, and the roller 23 is rotated again to insert the cleaning brush 21 into the endoscope conduit 31. By repeating this, brushing cleaning of the endoscope channel 31 is performed.
[0040]
Thereby, in the case of the endoscope 10 in which the endoscope conduit 31 is long, the roller 23 is controlled in a range where the number of magnets 19a passing is large, and in the case of the endoscope 10 in which the endoscope conduit 31 is short. Controls the roller 23 in a range where the number of passing magnets 19a is small. In addition, if the endoscope cleaning device notifies the user of an error when the required number of magnets 19a are not detected within a predetermined time, it is possible to confirm that the cleaning brush 21 is not operating normally. You can also notify users.
[0041]
As a method of detecting the length of insertion / removal of the cleaning brush 21, apart from the method of detecting the moving distance of the insertion portion 19 as described above, the number of rotations of the roller 23 controlling the insertion / removal of the cleaning brush 21 is determined. Alternatively, the length of insertion / removal of the cleaning brush 21 may be detected.
[0042]
As described above, when the endoscope conduit 31 is brushed by the cleaning brush 21, when the opening / closing valve 26 of the communication conduit 25 that connects the casing 22 of the roller housing 17 and the cleaning tank 11 is opened, this communication is performed. The cleaning liquid is injected into the pipe 25 and the cleaning liquid is poured into the cleaning tank 11. When the inside of the roller housing 17 begins to be filled with the cleaning liquid, the cleaning liquid and the air bubbles are in a mixed state, but the air bubbles collect on the ceiling surface 22 a of the casing 22 of the roller housing 17. Since the ceiling surface 22a is formed in a tapered shape centering on the opening 22b, the bubbles collected on the ceiling surface 22a collect in the opening 22b and pass through the opening 22b into the cleaning tank 11 via the communication pipe 25.
[0043]
Therefore, after a certain period of time, since the roller housing 17 is filled with the cleaning liquid without air bubbles, this portion is reliably cleaned. In addition, if the on-off valve 26 is always opened, the flow rate of the cleaning liquid to the endoscope conduit 31 is reduced, and the cleaning property of the endoscope conduit 31 is reduced. Thereafter, it is better to close the on-off valve 26 and to intensively flow the cleaning liquid into the endoscope conduit 31, thereby improving the cleaning efficiency of the endoscope conduit 31. Further, when the pump 13 is operated, the cleaning liquid and the air bubbles are mixed in the endoscope conduit 31 and the internal conduit 14, so that a load is applied to the pump 13 and noise is generated. By opening 26, these bubbles can be quickly removed, and there is also an effect of noise reduction.
[0044]
When the cleaning process is completed, the cleaning brush 21 is stored in the brush storage channel 15, and the water is removed by rinsing and operating the compressor 40 while the roller 23 of the roller storage unit 17 is stopped.
[0045]
Then, it enters a disinfection process. The disinfectant injected from the disinfectant tank 34 into the cleaning tank 11 by the operation of the disinfectant pump 35 is operated by the pump 13 to store the pipeline 14, the brush storage pipeline 15, the roller storage 17, and the magnetic sensor storage. It is injected into the endoscope conduit 31 via the connection conduit 30 via the part 18.
[0046]
At this time, similarly to the washing step, the on-off valve 26 installed in the communication pipe 25 communicating with the opening 22b of the ceiling surface 22a of the casing 22 of the roller housing 17 is opened, and the roller housing 17 is securely closed. Disinfection. During the disinfection process, the operating parts (the roller 23 and the cleaning brush 21) are not basically operated, but by operating this, air bubbles slightly adhering to the roller 23 and the cleaning brush 21 may be removed.
[0047]
After the disinfectant is immersed for a certain period of time, when the disinfectant filled in the cleaning tank 11 is collected in the disinfectant tank 34 by the operation of the switching valve 33, the disinfectant pump 35 is operated, and the inner pipe of the apparatus is operated. Since the disinfecting liquid in the passage 14, the brush accommodating conduit 15, the roller accommodating portion 17 and the like is removed and returned to the cleaning tank 11 via the endoscope conduit 31, this amount is also collected in the disinfecting liquid tank 34. Thereafter, rinsing is performed several times, and finally, water is removed again, and the endoscope 10 is washed and disinfected by the apparatus.
[0048]

When the insertion portion 19 is made of metal such as a wire as in the first embodiment, there is a possibility that the magnetic sensor 28 may perform erroneous detection. Therefore, as shown in FIGS. Alternatively, the pipe 37a made of a synthetic resin material may be connected to form an insertion portion 37, and a magnet 38 may be incorporated between the pipes 37a.
[0049]
6A and 6B show a third embodiment, in which FIG. 6A is a side view of a cleaning brush, and FIG. 6B is an enlarged sectional view of a portion B. As in the first embodiment, the cleaning brush 21 comes into contact with a cleaning solution or a disinfecting solution. Therefore, from the viewpoint of chemical resistance, the magnet 38 may be provided inside the insertion portion 37 made of a synthetic resin material, or the magnet 38 may be covered with a synthetic resin film.
[0050]
FIG. 7 shows a fourth embodiment, which may be configured as follows as a means for removing air bubbles in the roller housing 17. That is, the cleaning brush outlet opening 39a is provided above the casing 22 of the roller housing 17, and the cleaning brush inlet opening 39b is provided below. The cleaning brush outlet opening 39a is formed in a tapered shape around the opening.
[0051]
When the cleaning liquid or the disinfecting liquid from the cleaning tank 11 is injected into the roller storage unit 17 from the cleaning brush inlet opening 39b by the operation of the pump 13 as in this embodiment, the cleaning is first performed in the roller storage unit 17. Although the liquid or the disinfecting liquid and the air bubbles are in a mixed state, the air bubbles gather upward. The bubbles collected upward are discharged from the brush outlet opening 39a, which is the center of the tapered shape, into the cleaning tank 11 via the endoscope conduit 31. Thus, the bubbles in the roller housing 17 can be removed during the cleaning and disinfecting process, so that the roller housing 17 can be reliably washed / disinfected.
