  The processing tank 4 is provided with a leak test connector 35 having a first air supply port 150s.

  During the leak test of the endoscope 100, a connector 180b provided at the other end of the tube 180 is connected to the first air supply port 150s of the connector 35 for leak test. In the leak test of the endoscope 100, the connector 180 a provided at one end of the tube 180 is connected to the leak test port 101 of the endoscope 100.

  The first air supply port 150s is provided with an on-off valve (not shown), and the on-off valve opens only when the connector 180b is connected, that is, a configuration in which the first air supply port 150s is opened is a connector 35 for leak test. Have. In other words, the first air inlet 150s is closed when the connector 180b is not connected.

  In the leak test of the endoscope 100, the endoscope 100 may be directly connected to the leak test port 101 without passing through the tube 180 at the first air supply port 150s.

  The first air supply port 150 s is connected by an air supply pump 45 provided in the endoscope reprocessor 1 and a first conduit 150. The air supply pump 45 is driven and controlled by a control unit 70 provided in the endoscope reprocessor 1.

  Further, in the processing tank 4, a second air supply port 160s is opened toward the first air supply port 150s.

  The second air supply port 160s constitutes the other end of the second pipe line 160 provided in the endoscope reprocessor 1, and one end of the second pipe line 160 is supplied to the first pipe line 150. It is connected downstream of the air pump 45. That is, the second pipe line 160 connects the air supply pump 45 and the second air supply port 160 s via the first pipe line 150.

  The air supply pump 45 is a first air supply pump for supplying the gas A to the first air supply port 150s through the first pipe line 150, and a second air supply port 160s through the second pipe line 160. And a second air supply pump for supplying the gas A to the unit. However, the present invention is not limited to this, and a first air supply pump for supplying the gas A to the first air supply port 150s via the first pipe line 150, and a second gas supply via the second pipe line 160. It may be separate from the second air supply pump that supplies the gas A to the air port 160s.

  In addition, as shown in FIG. 1, when the second air supply port 160s is opened downward to point to the bottom surface of the processing tank 4, the liquid dropped from the upper side of the second air supply port 160s is secondly supplied. It becomes difficult to infiltrate into the 2nd pipe line 160 via 160 s of openings.

  In addition, even if the second air supply port 160s is not opened downward, an eave or the like may be provided on the upper side of the second air supply port 160s in order to prevent the liquid from entering the second pipeline 160. .

  Further, an on-off valve 170 which is opened and closed by the control of the control unit 70 is disposed in the second pipe line 160. Thus, the air supply pump 45 is disposed upstream of the on-off valve 170.

  In addition, since the structure of the other endoscope reprocessor 1 is known, the description is abbreviate | omitted.

  Next, the operation of the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing various drive control of the control unit at the time of a leak test in the endoscope reprocessor of FIG.

  When performing a leak test, first, in step S1, when the control unit 70 detects that the detection unit 99 has read endoscope information of the endoscope 100, the control unit 70 closes the on-off valve 170 in step S2. Perform control (close valve CLOSE).

  Next, the control unit 70 performs control to drive the air supply pump 45 (air supply pump ON). As a result, since the on-off valve 170 is closed and the first air supply port 150s is closed when the connector 180b is not connected, the inside of the first pipeline 150 is pressurized.

  Thereafter, in step S4, the control unit 70 performs control to open the on-off valve 170 (on-off valve OPEN), and the pressure in the first pipe line 150 is transmitted from the second air supply port 160s through the second pipe line 160. Released. That is, the gas in the first conduit 150 is released from the second air port 160 s via the second conduit 160.

  At this time, since the second air port 160s is opened toward the first air port 150s, the gas A discharged from the second air port 160s is directed to the first air port 150s. Be sprayed.

  Therefore, when the water droplet W adheres to the upper surface 35 j of the leak test connector 35, the water droplet W is blown away by the gas A discharged from the second air supply port 160 s.

  Next, in step S5, the control unit 70 performs control to close the on-off valve 170 (on-off valve CLOSE). As a result, since the on-off valve 170 is closed and the first air supply port 150s is closed when the connector 180b is not connected, the inside of the first pipeline 150 is pressurized again. Further, the inside of the second pipe 160 returns to the atmospheric pressure.

  In a state in which the inside of the first pipeline 150 is pressurized, the control unit 70 detects whether or not the connector 180 b of the tube 180 is connected to the leak test connector 35 from the pressure change in the first pipeline 150. Do.

  After that, when it is detected that the connector 180 b is connected to the leak test connector 35, the control unit 70 drives the air supply pump 45 for a certain period of time to perform the leak test, and thereby the first pipe line in the endoscope 100. After the gas A is supplied through the first air supply port 150s, the tube 180, and the leak test port 101, the control of stopping the operation of the air supply pump 45 is finally performed in step S6 (air supply pump OFF). Thereafter, a pressure change in the endoscope 100 is detected to perform a leak test.

  Thus, in the present embodiment, the second air supply port 160s of the second pipeline 160 is directed to the first air supply port 150s of the leak test connector 35 to which the tube 180 is connected in the processing tank 4. Indicated that it was open.

  Since the endoscope reprocessor 1 is configured to be able to supply the gas A from the second air supply port 160s toward the first air supply port 150s, the first refueling of the upper surface 35j of the leak test connector 35 is performed. It is possible to blow off the water droplets W attached around the vent 150s.

  In addition, the second conduit 160 is connected to the first conduit 150, and when the detection unit 99 reads endoscope information of the endoscope 100, the air supply pump 45 provided in the first conduit 150. It is indicated that the on-off valve 170 provided in the second conduit 160 is opened and the gas is sprayed from the second air supply port 160s toward the first air supply port 150s as the

  When the detection unit 99 reads the endoscope information, before the connector 180b of the tube 180 is connected to the leak test connector 35, the supply of the gas A from the second air supply port 160s to the first air supply port 150s. Thus, it is possible to automatically blow off the water droplets W attached around the first air supply port 150s on the upper surface 35j of the leak test connector 35.

  Therefore, when the connector 180b is connected to the leak test connector 35, the water droplets W on the upper surface 35j are prevented from infiltrating into the first conduit 150 via the first air supply port 150s. it can.

  Furthermore, after the gas A is supplied from the second air supply port 160s and the water droplets W are blown away, the on-off valve 170 is closed to repressurize the inside of the first conduit 150, thereby connecting the connector 180b to the leak test connector 35. The connection detection can also be performed by a series of operation control by the control unit 70.

From the above, it is possible to provide the endoscope reprocessor 1 having a configuration capable of automatically removing water droplets around the air supply port at the time of the leak test (second embodiment)
FIG. 3 is a diagram schematically showing the configuration of the endoscope reprocessor according to the present embodiment.

  The configuration of the endoscope reprocessor according to the second embodiment is different from the configuration of the endoscope reprocessor according to the first embodiment shown in FIG. 1 and FIG. It differs in that the opening position of is specified.

  Therefore, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 3, in the present embodiment, the cover 3 can be freely opened and closed with respect to the processing tank 4, and the second air supply port 160 s is a processing tank when the cover 3 is closed to the processing tank 4. It is opened in the area | region 3g outside the part covered with the cover 3 in 4.

  The first air supply port 150s, that is, the leak test connector 35 is disposed in a region within the portion 3i covered by the cover 3 in the processing tank 4. Further, the other configuration is the same as that of the first embodiment described above.

  Next, the operation of the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing various drive control of the control unit at the time of the leak test in the endoscope reprocessor of FIG. 3.

  When performing a leak test, first, in step S1, when the control unit 70 detects that the detection unit 99 has read endoscope information of the endoscope 100, the control unit 70 closes the on-off valve 170 in step S2. Perform control (close valve CLOSE).

  Next, the control unit 70 performs control to drive the air supply pump 45 (air supply pump ON). As a result, since the on-off valve 170 is closed and the first air supply port 150s is closed when the connector 180b is not connected, the inside of the first pipeline 150 is pressurized.

  Next, the process proceeds to step S10, where the control unit 70 determines whether the cover 3 is open with respect to the processing tank 4. If the cover 3 is closed, the second air supply port 160s is disposed in the region of 3g outside the region covered by the cover 3, so the cover 3 interferes with gas from the second air supply port 160s. Since A can not be sprayed to the first air supply port 150s, the determination in step S3 is continued until it is detected that the cover 3 has been opened.

  Even if the liquid has infiltrated into the second conduit 160, the liquid is blocked by the on-off valve 170 and enters the second conduit 160 upstream of the on-off valve 170. Therefore, the liquid does not enter the first conduit 150.

  Furthermore, as shown in steps S2 and S3 described above, the control unit 70 performs control to open the on-off valve 170 after pressurizing the inside of the first pipe line 150, so the control section 70 enters the second pipe line 160. It is also possible to discharge the liquid from the second air port 160s.

The first pipe line 150 connects the first air supply pump and the first air supply port 150s, and the second pipe line 160 connects the second air supply pump and the second air supply port 160s. It does not matter if it is provided. In this case, the on-off valve 170 is unnecessary. The first air supply pump and the second air supply pump are controlled by the control unit 70 respectively.

  Further, in order to supply the dried gas A from the second air supply port 160s toward the first air supply port 150s, a hygroscopic filter may be provided in the second pipeline 160, or a heater may be provided. It is good.

  Furthermore, it has been shown that the water droplets W on the upper surface 35j of the leak test connector 35 are removed by supplying the gas A from the second air supply port 160s toward the first air supply port 150s, but the invention is not limited thereto.
