Description

  The present invention relates to an endoscope reprocessor in which an air supply port to which an endoscope or a tube is connected is arranged in a processing tank in which an endoscope is arranged.

  When performing a leak test of an endoscope by detecting the pressure change inside the endoscope by supplying air into the endoscope before using the endoscope reprocessor There is.

  Specifically, the endoscope water leakage detection is performed by connecting one end of the tube to the endoscope leak test port disposed in the endoscope reprocessor processing tank and the endoscope reprocessor processing tank. In the state where the other end of the tube is connected to the air supply port of the leak test connector placed in the air supply port, the air supply pump provided in the conduit communicating with the air supply port is driven, and the tube, leak This is performed by supplying gas into the endoscope through the test port.

  Here, when connecting the leak test connector of the tube or endoscope to the leak test connector, if the leak test connector is wet, water droplets around the air supply port on the leak test connector pass through the air supply port. Intrusion into the leak test connector, that is, into the pipeline.

  Therefore, if air is supplied into the endoscope in a state where water droplets have entered the leak test connector, not only gas but also water droplets are supplied into the endoscope.

  Therefore, the operator needs to wipe off moisture from the leak test connector before connecting the leak test port of the tube or endoscope to the leak test connector, which is troublesome.

  In view of such circumstances, Patent Document 1 discloses that the liquid in the treatment tank is reverse to the pipe line connected to the connector in order to prevent the liquid from entering the tube connection connector disposed in the treatment tank. A configuration in which a stop valve is provided is disclosed. A configuration in which a check valve is provided in the connector is also well known.

  However, since the check valve has a large individual difference in the cracking pressure as is well known, if the check valve is provided in the pipe connected to the leak test connector or in the leak test connector, the check valve is inspected in the leak test. There was a problem that the pressure change inside the mirror could not be detected accurately.

  Therefore, in the leak test, when connecting the leak test port of the tube or endoscope to the leak test connector, water drops enter the leak test connector through the air supply port without using a check valve. A configuration that can prevent this has been desired.

  The present invention is for solving the above-described problems, and provides an endoscope reprocessor having a configuration capable of automatically removing water droplets around an air supply port during a leak test. Objective.

  FIG. 1 is a diagram schematically showing the configuration of the endoscope reprocessor according to the present embodiment.

  As shown in FIG. 1, the endoscope reprocessor 1 includes a processing tank 4 in which the endoscope 100 is disposed in the apparatus main body 2.

  In addition, a detection unit 99 that reads endoscope information of the endoscope 100 arranged in the processing tank 4 and transmits the endoscope information to the control unit 70 provided in the endoscope reprocessor 1 includes an endoscope. The mirror reprocessor 1 is provided on the upper surface of the apparatus main body 2.

  In addition, as the detection unit 99, endoscope information is directly input by an RFID that reads a scope ID provided in the endoscope 100, a reader that reads a barcode provided in the endoscope 100, or an operator. A panel etc. are mentioned.

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

  The connector 180b provided at the other end of the tube 180 is connected to the first air supply port 150s of the leak test connector 35 at the time of the leak test of the endoscope 100. In the leak test of the endoscope 100, the connector 180a 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 open / close valve (not shown), and the open / close valve is opened only when the connector 180b is connected, that is, the leak test connector 35 is configured to open the first air supply port 150s. Has. In other words, the first air supply port 150s is closed when the connector 180b is not connected.

  Further, 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 to the first air supply port 150s.

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

  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 160 s constitutes the other end of the second pipeline 160 provided in the endoscope reprocessor 1, and one end of the second pipeline 160 is fed to the first pipeline 150. It is connected to the downstream side 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 includes a first air supply pump that supplies the gas A to the first air supply port 150s through the first pipe 150, and a second air supply port 160s through the second pipe 160. And a second air supply pump for supplying the gas A. However, the present invention is not limited to this, and the first air supply pump that supplies the gas A to the first air supply port 150 s via the first pipe 150 and the second air supply via the second pipe 160. It may be a separate body from the second air supply pump that supplies the gas A to the air mouth 160s.

  As shown in FIG. 1, when the second air supply port 160s is opened downward so as to face the bottom surface of the processing tank 4, the liquid dripping from the upper side of the second air supply port 160s is supplied to the second air supply port 160s. It becomes difficult to enter the second pipe line 160 through the air port 160s.

  Even if the second air supply port 160s is not opened downward, an eaves or the like may be provided on the upper side of the second air supply port 160s in order to prevent liquid from entering the second pipe 160. .

  An opening / closing valve 170 that is opened and closed under the control of the control unit 70 is disposed in the second pipeline 160. Therefore, the air supply pump 45 is disposed upstream of the on-off valve 170.

  Since the configuration of the other endoscope reprocessor 1 is well known, the description thereof is omitted.

  Next, the effect | action of this Embodiment is demonstrated using FIG. FIG. 2 is a flowchart showing various drive controls of the control unit during the leak test in the endoscope reprocessor of FIG.

  When performing the leak test, first, in step S1, the control unit 70 detects that the detection unit 99 has read the endoscope information of the endoscope 100. In step S2, the control unit 70 closes the on-off valve 170. Control is performed (open / 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 conduit 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 changed from the second air supply port 160s through the second pipe line 160. Released. That is, the gas in the first pipeline 150 is released from the second air supply port 160 s through the second pipeline 160.

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

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

  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 conduit 150 is pressurized again. Further, the inside of the second pipeline 160 returns to the atmospheric pressure.

  In a state where the inside of the first conduit 150 is pressurized, the control unit 70 detects whether the connector 180b of the tube 180 is connected to the leak test connector 35 from the pressure change in the first conduit 150. To do.

  Thereafter, when it is detected that the connector 180b 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 enter the first pipe line in the endoscope 100 for the leak test. 150, the gas A is supplied through the first air supply port 150s, the tube 180, and the leak test port 101, and finally, in step S6, the drive of the air supply pump 45 is stopped (air supply pump). OFF). Thereafter, a pressure change in the endoscope 100 is detected and a leak test is performed.

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

  Since the endoscope reprocessor 1 has a configuration capable of supplying the gas A from the second air supply port 160 s toward the first air supply port 150 s, the first resupply on the upper surface 35 j of the leak test connector 35. It is possible to blow away the water droplets W attached around the mouth 150s.

  The second pipeline 160 is connected to the first pipeline 150, and when the detection unit 99 reads the endoscope information of the endoscope 100, the air supply pump 45 provided in the first pipeline 150. It is shown that the on-off valve 170 provided in the second pipe line 160 is opened and gas is blown from the second air supply port 160s toward the first air supply port 150s.

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

  For this reason, when the connector 180b is connected to the leak test connector 35, it is possible to prevent the water droplets W on the upper surface 35j from entering the first pipeline 150 through the first air supply port 150s. it can.

  Further, after supplying the gas A from the second air supply port 160s and blowing off the water droplets W, the open / close valve 170 is closed and the inside of the first pipe line 150 is repressurized, whereby the connector 180b for the leak test connector 35 is obtained. 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 during the leak test (second embodiment).
FIG. 3 is a diagram schematically showing a configuration of the endoscope reprocessor according to the present embodiment.

  Compared with the configuration of the endoscope reprocessor of the first embodiment shown in FIGS. 1 and 2, the configuration of the endoscope reprocessor of the second embodiment is the second air supply port in the processing tank. The difference is that the opening position is defined.

  Therefore, the same components as those in 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 opened and closed with respect to the processing tank 4, and the second air supply port 160 s is disposed in the processing tank when the cover 3 is closed by the processing tank 4. 4 is opened in a region 3 g outside the region covered with the cover 3.

  The first air supply port 150 s, that is, the leak test connector 35, is disposed in a region in the portion 3 i covered with the cover 3 in the processing tank 4. Other configurations are the same as those in the first embodiment described above.

  Next, the effect | action of this Embodiment is demonstrated using FIG. FIG. 4 is a flowchart showing various drive controls of the control unit during the leak test in the endoscope reprocessor of FIG.

  When performing the leak test, first, in step S1, the control unit 70 detects that the detection unit 99 has read the endoscope information of the endoscope 100. In step S2, the control unit 70 closes the on-off valve 170. Control is performed (open / 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 conduit 150 is pressurized.

  Next, the process proceeds to step S <b> 10, and the control unit 70 determines whether or not 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 3g outside the region covered with the cover 3, so that the cover 3 obstructs the gas from the second air supply port 160s. Since A cannot be sprayed onto the first air inlet 150s, the determination in step S3 is continued until it is detected that the cover 3 has been opened.

  Note that the operation control of the control unit 70 after step S4 after detecting that the cover 3 has been opened is the same as that in the first embodiment described above, and a description thereof will be omitted.

  As described above, in the present embodiment, when the cover 3 is closed to the processing tank 4, the second air supply port 160 s is arranged in the region 3 g outside the part covered with the cover 3 in the processing tank 4. Indicated.

  According to this, in the chemical treatment process of the endoscope 100 that does not involve a leak test performed in the state where the cover 3 is covered in the treatment tank 4, liquid such as chemical or water adheres to the second air supply port 160s. Therefore, the liquid can be prevented from entering the second pipeline 160 through the second air supply port 160s.

  Even if the liquid enters the second pipe 160, the liquid is blocked by the on-off valve 170 and enters the upstream side of the on-off valve 170 in the second pipe 160. 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 pressurize the inside of the first pipeline 150 and then open the on-off valve 170, so that the controller 70 enters the second pipeline 160. The discharged liquid can be discharged from the second air supply port 160s.

  Other effects are the same as those of the first embodiment described above.

Provided separately, the first conduit 150 connects the first air pump and the first air inlet 150s, and the second conduit 160 connects the second air pump and the second air inlet 160s. It may be provided as follows. In this case, the on-off valve 170 is not necessary. The first air pump and the second air pump are driven and controlled by the controller 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 moisture absorption filter or a heater may be provided in the second pipeline 160. May be.

  Furthermore, it has been shown that the water droplet W on the upper surface 35j of the leak test connector 35 is removed by supplying the gas A from the second air supply port 160s toward the first air supply port 150s. Needless to say, the water droplets W may be removed by supplying a highly volatile liquid such as, for example.
