Description

  The present invention relates to a reprocessing apparatus that performs a reprocessing process on a medical device such as an endoscope after use.

  In medical institutions, medical diagnosis using an endoscope is actively performed. Endoscopes used in medical diagnosis are set in an endoscope cleaning device and cleaned (cleaning, disinfecting, rinsing, and drying) in order to prevent disease infection. The cleaning device includes a cleaning tank in which the endoscope is accommodated and an openable / closable lid that covers the cleaning tank.

  When the cleaning process is performed by the cleaning apparatus, cleaning information indicating who operated the apparatus and which endoscope has been subjected to the cleaning process is acquired. For example, an RFID tag (information storage unit) is provided on each of the endoscope operation unit and the operator ID card. Before starting the cleaning process, an endoscope ID and an operator ID are acquired from each RFID tag by a tag reader / writer (wireless communication means) installed outside the cleaning tank of the cleaning device (see Patent Document 1).

  As the RFID tag, a short distance type having a communication distance of several centimeters is used in order to reduce the cost. Therefore, the operator brings the endoscope and ID card close to or in contact with the tag reader / writer, thereby establishing communication between the two and causing the tag reader / writer to acquire various information.

  By the way, dirt is adhered to the endoscope after use, and the operator's hand touches the operation part that is not inserted into the human body, and the dirt adheres. Therefore, in Patent Document 2, when the operator brings the operation unit of the endoscope into contact with the tag reader / writer, the tag reader / writer is contaminated. In addition, even when the operation unit is brought close to the tag reader / writer, the tag reader / writer may be contaminated by dirt on the operation unit dropping on the tag reader / writer. When the tag reader / writer is contaminated, it is necessary for the operator to wipe the surface of the tag reader / writer, which causes a problem that the work of the operator increases.

Patent Document 2 describes an endoscope cleaning / disinfecting apparatus in which a tag reader / writer is disposed in a cleaning tank. By providing the tag reader / writer in the cleaning tank, the tag reader / writer is also cleaned at the same time when the endoscope is cleaned, so that contamination of the tag reader / writer is removed. As a result, the decontamination work by the operator becomes unnecessary.

  As shown in FIG. 3, a channel cleaning port 38 is provided on the first vertical surface 37 a of the inner side surface 37. The channel cleaning port 38 is provided with an air / water channel coupler 39, a suction channel coupler 40, a forceps channel coupler 41, and a drying nozzle (dry air blowing means) 42.

  The couplers 39 to 41 are connected to the mounting ports 33a and 33b and the forceps port 33c of the endoscope 12 by flexible tubes 44 to 46, respectively. From each coupler 39-41, liquids and gases, such as water, a detergent, disinfection liquid, alcohol, and dry air (compressed air), are supplied in each channel in the endoscope 12. The tip of the drying nozzle 42 is directed to the inclined surface 37b substantially vertically downward, and the drying air is blown toward the inclined surface 37b.

  An endoscope tag (first information storage means) 48 is provided in a part of the operation unit 33 of the endoscope 12. The endoscope tag 48 is a passive tag similar to the card tag 24 described above, and includes a memory storing an endoscope ID and cleaning / disinfection result information in addition to the antenna and the power conversion circuit described above. The endoscope ID is identification information assigned to identify each endoscope 12. The cleaning / disinfection result information includes, for example, the details of the cleaning process performed on the endoscope 12 (the number of cleanings, the number of disinfections, the number of rinsings), the conditions of the cleaning process (type of processing liquid, temperature, etc.), It consists of the date of execution, operator ID, etc.

  On the inclined surface 37b, the water surface (liquid surface) S of the processing liquid that fills the cleaning tank 14 at the position near the operation unit 33 and vertically below the drying nozzle 42 described above and during the cleaning process (FIG. 4). Reference) An endoscope tag reader / writer unit (hereinafter simply referred to as an R / W unit) 49 is attached at the following position. However, the R / W unit 49 operates when there is no processing liquid in the cleaning tank 14.

  In FIG. 4 showing a cross section taken along line IV-IV in FIG. 3, an R / W unit 49 includes an endoscope tag reader / writer (hereinafter referred to as an endoscope tag R) corresponding to the wireless communication means of the present invention. / W) 51 and a holding member 52 for holding the endoscope tag R / W 51.

  The endoscope tag R / W 51 transmits an ID request to the endoscope tag 48 before the start of the cleaning process, and an endoscope ID transmitted from the endoscope tag 48 in response to the ID request. Receive. Further, the endoscope tag R / W 51 writes the cleaning / disinfecting result information into the endoscope tag 48 after the cleaning process is completed. Since the endoscope tag 48 is a passive tag, the communicable distance between the endoscope tag 48 and the endoscope tag R / W 51 is about several centimeters. Therefore, when the operation unit 33 of the endoscope 12 is set at the cleaning set position (see FIG. 2) located in the vicinity of the inner side surface 37 of the cleaning tank 14, the endoscope tag 48 and the endoscope tag R The distance to / W51 falls within the range of the above-described communicable distance, and both communications are established.

  When the R / W unit 49 is attached to the cleaning tank 14, if there is a conductor in the immediate vicinity of the endoscope tag R / W 51, radio waves inputted to and outputted from the endoscope tag R / W 51 are conducted. Since it flows to the body and attenuates, the aforementioned communicable distance is drastically reduced. For this reason, the endoscope tag R / W 51 cannot be directly attached to the cleaning tank 14 made of SUS. Further, since the radio wave is not transmitted in the liquid, even when the processing liquid remains on the R / W unit 49, the radio wave is attenuated and the communicable distance is drastically reduced.

  Therefore, in this embodiment, in order to prevent the radio wave from being attenuated by the cleaning tank 14 made of SUS, the cleaning tank 14 (inclined surface 37b) is cut out, and the R / W unit 49 is attached to the cut-out portion. It is attached. Further, in order to prevent the radio wave from being attenuated due to residual liquid, the R / W unit 49 is attached to a position vertically below the drying nozzle 42 (dry air blowing position) on the inclined surface 37b. Further, the R / W unit 49 is attached at a position in contact with the processing liquid during the cleaning process so that dirt (contamination) attached to the R / W unit 49 is removed by the cleaning process of the endoscope 12. .

  A notch 54 is formed at a position vertically below the drying nozzle 42 on the inclined surface 37b. The opening area of the cutout hole 54 is sufficiently larger than the endoscope tag R / W51. Since the notch 54 is formed at a position lower than the water surface S of the processing liquid during the cleaning process, the notch hole 54 is liquid-tightly closed by the holding member 52.

  The holding member 52 is formed of a radio wave transmitting material (for example, ABS resin) that can transmit radio waves, and a fitting portion 52a that fits the cutout hole 54 in a liquid-tight manner, and a rear end of the fitting portion 52a. And a flange portion 52b integrally formed on the periphery of the portion. The fitting portion 52a is fitted in the notch hole 54 so that the flange portion 52b is located outside the cleaning tank 14. In the present embodiment, the surface of the fitting portion 52a and the inclined surface 37b are flush with each other.

  A plurality of screw insertion holes 56 are formed in the peripheral portion of the cutout hole 54 in the inclined surface 37b. Male screws 57 are respectively inserted into the screw insertion holes 56 from the inside of the cleaning tank 14, and each male screw 57 is screwed into a female screw portion 58 formed in the flange portion 52 b of the holding member 52. Thereby, the holding member 52 is fixed to the back surface of the inclined surface 37b. An O-ring 59 is provided between the flange portion 52b and the back surface of the inclined surface 37b in order to prevent liquid leakage. The O-ring 59 is fitted in an annular groove 60 formed on the surface of the flange portion 52b (a surface facing the inclined surface 37b) and is crushed by tightening the male screw 57.

  A plurality of screw insertion holes 61 are formed in the peripheral portion of the endoscope tag R / W 51. Each screw insertion hole 61 is inserted with a male screw 62 from the back surface side, and each male screw 62 is screwed into a female screw portion 63 formed on the back surface of the fitting portion 52a. Thereby, R / W51 for endoscope tags is fixed to the back of fitting part 52a.

  Thus, the endoscope tag R / W 51 is held by the holding member 52 in a state of being inserted into the cutout hole 54 from the outside of the cleaning tank 14. Thereby, a predetermined space is secured between the endoscope tag R / W 51 and the cleaning tank 14 (periphery of the cutout hole 54). The size of this interval is determined by the size of the cutout hole 54 and is at least large enough to prevent radio waves input to and output from the endoscope tag R / W 51 from flowing into the cleaning tank 14.

  After completion of the cleaning process, the treatment liquid remaining on the surfaces of the inclined surface 37b and the fitting portion 52a flows down to the second vertical surface 37c along these inclinations. Furthermore, in this embodiment, the water repellent coat is given to the surface of the inclined surface 37b and the fitting part 52a. Thereby, the processing liquid on the surfaces of the inclined surface 37b and the fitting portion 52a is more likely to flow down to the second vertical surface 37c. In addition, although the inclination angle of the inclined surface 37b is not specifically limited, the larger one (for example, 45 degrees or more with respect to the water surface S) is preferable.

  Further, drying air is blown to the fitting portion 52a (inclined surface 37b) from the drying nozzle 42 arranged vertically above. This blowing of dry air is performed for a predetermined time (for example, 1 minute) immediately after the cleaning process is completed, for example. As described above, (a) the inclined surface 37b and the fitting portion 52a are inclined, (b) the water-repellent coat, and (c) the drying air is sprayed to reliably remove the processing liquid on the surface of the fitting portion 52a. Can do.

  As shown in FIG. 5, the cleaning apparatus 10 includes a CPU 65 that controls the entire apparatus, a ROM 66 that stores a control program and various data, and a RAM 67 that is an execution area of the control program read from the ROM 66. It has. In addition to various sensors such as the lid detection sensor 18 and the liquid level sensor 29, the CPU 65 includes an operation panel 19, an LCD driver 68 for driving the display panel 20, a speaker 21, a card tag reader 22, an endoscope tag R / R. W51, motor driver 69, valve driver 70, and the like are connected.

  The motor driver 69 supplies a liquid supply pump (detergent and disinfectant liquid from the above-described detergent tank and disinfectant tank to the respective parts of the washing tank 14 (detergent supply nozzle 27, disinfectant liquid supply nozzle 28, channel cleaning port 38, etc.) The motor 72 of the air supply pump (not shown) which supplies dry air to the motor 72 and the channel washing | cleaning port 38 grade | etc., Etc. are driven.

  The valve driver 70 drives a solenoid valve (not shown) provided in a pipe line connecting the tap water faucet, each tank, and the air supply pump, and each of the nozzles 26 to 28 and the channel cleaning port 38. Control. Thereby, switching of supply / stop of supply of water, detergent, and disinfectant from each nozzle 26 to 28 can be performed. Further, switching of supply / supply stop of the cleaning liquid (water + detergent), disinfecting liquid, and drying air to the couplers 39 to 41 of the channel cleaning port 38 and switching of supply / supply stop of the drying air to the drying nozzle 42 are performed. It can be performed.

  Next, the operation of the cleaning apparatus 10 having the above configuration will be described with reference to the flowchart of FIG. The operator operates the operation panel 19 to turn on the power of the cleaning device 10, unlocks the lid 15, and then rotates the lid 15 from the closed position to the open position.

  The CPU 65 operates the card tag reader 22 and the endoscope tag R / W 51 when the lid 15 is rotated to the open position based on the detection result of the lid detection sensor 18. Then, the operator sets the endoscope 12 in the cleaning tank 14.

  At this time, in the present embodiment, since the cleaning tank 14 around the endoscope tag R / W 51 is cut out, radio waves input to and output from the endoscope tag R / W 51 are supplied to the cleaning tank 14. There is no flow, and the communicable distance between the endoscope tag R / W 51 and the endoscope tag 48 does not drastically decrease. Therefore, when the operation unit 33 of the endoscope 12 is set at the above-described cleaning set position, the endoscope tag 48 and the endoscope tag R / W 51 can communicate with each other. Thereby, the endoscope tag R / W 51 acquires the endoscope ID from the endoscope tag 48. In addition to the endoscope ID, the previously stored cleaning / disinfection result information may be acquired at the same time.

  After the endoscope tag R / W 51 acquires the endoscope ID and the like, the CPU 65 outputs a confirmation sound such as “pick!” From the speaker 21 and controls the LCD driver 68 to control the endoscope tag. The information acquired from 48 is displayed on the display panel 20. After confirming the output of the confirmation sound, the operator rotates the lid 15 to the closed position. Then, the CPU 65 controls the LCD driver 68 when the lid 15 is rotated to the closed position based on the detection result of the lid detection sensor 18, such as “Please contact the ID card with the card tag reader”. The message is displayed on the display panel 20.

  When the operator makes the ID card 23 contact the card tag reader 22 according to the message, the card tag reader 22 acquires the operator ID from the card tag 24. Also at this time, the CPU 65 outputs a confirmation sound from the speaker 21.

  Next, the operator performs an operation for starting the cleaning process on the operation panel 19. When this start operation is performed, the CPU 65 checks whether or not all pre-cleaning information including the endoscope ID and the operator ID has been acquired. When all the pre-cleaning information is acquired, the CPU 65 locks the lid 15 and then drives the motor driver 69 and the valve driver 70 to execute the cleaning process (cleaning, disinfection, rinsing, and drying). . In addition, since the specific content of the washing process is well-known, description is abbreviate | omitted here. When the cleaning process is executed, dirt attached to the endoscope tag R / W 51 is also removed.

  Conversely, the CPU 65 outputs an error sound (chime) from the speaker 21 and controls the LCD driver 68 when the cleaning process is started without acquiring all the pre-cleaning information. An error message such as “Please contact the card tag (endoscope tag) with the card tag reader (R / W unit)” is displayed on the display panel 20.

  According to the error message, the operator contacts the card tag 24 with the card tag reader 22 or opens the lid 15 to bring the endoscope tag 48 into contact with the R / W unit 49. The CPU 65 continues outputting the error sound and displaying the error message until all the pre-cleaning information is acquired. Then, after all the pre-cleaning information is acquired, when the operator performs the cleaning operation start operation again, the cleaning process is started as described above. It should be noted that even when the error sound output / error message display continues, the operator may operate the operation panel 19 or the like to forcibly start the cleaning process.

  When the cleaning process is completed, all the processing liquid is drained from the cleaning tank 14. At this time, the treatment liquid on the surfaces of the inclined surface 37b and the fitting portion 52a to which the water-repellent coat is applied flows down to the second vertical surface 37c along these inclinations. Further, after the cleaning process is completed, the CPU 65 controls the motor driver 69 and the valve driver 70 to blow dry air from the drying nozzle 42 toward the fitting portion 52a and the inclined surface 37b for a predetermined time. Thereby, a process liquid is completely removed from the surface of the fitting part 52a.

  After the drying air blowing operation is completed, the CPU 65, for example, the cleaning processing program (the number of times of cleaning, the number of times of disinfection, the number of times of rinsing, the temperature conditions), the type of detergent and the disinfectant previously input, and the operator ID acquired earlier. Based on the above, new cleaning / disinfection result information is generated. Further, the CPU 65 generates cleaning history information obtained by adding the endoscope ID to the cleaning / disinfecting result information, and transmits the cleaning history information to a management server (not shown) connected to the cleaning device 10 via a LAN.

  Next, the CPU 65 drives the endoscope tag R / W 51 to send a response request. When the response signal transmitted from the endoscope tag 48 in response to the response request is received by the endoscope tag R / W 51, the CPU 65 determines that both are in a communicable state. Then, the CPU 65 transmits new cleaning / disinfecting result information from the endoscope tag R / W 51 and writes the new cleaning / disinfecting result information in the memory of the endoscope tag 48. The CPU 65 controls the LCD driver 68 to display a message such as “please take out the endoscope” on the display panel 20 and unlock the lid 15. The operator removes the endoscope 12 from the cleaning tank 14 after opening the lid 15 according to the message.

  Conversely, when the response signal from the endoscope tag 48 is not received by the endoscope tag R / W 51, the CPU 65 determines that the two are not in a communicable state, controls the LCD driver 68, An error message such as “Please contact the endoscope tag with the R / W unit” is displayed on the display panel 20 and a warning sound is output from the speaker 21. Further, the CPU 65 releases the lock of the lid 15.

  The operator opens the lid 15 according to the error message and brings the endoscope tag 48 into contact with the R / W unit 49. The CPU 65 continues outputting the error sound and displaying the error message until new cleaning / disinfecting result information is written in the endoscope tag 48 by the endoscope tag R / W 51. The operator removes the endoscope 12 from the cleaning tank 14 after the output of the error sound and the display of the error message are stopped.

  As described above, in the present invention, the radio wave input / output to / from the endoscope tag R / W 51 is cut out from the SUS (cleaning tank 14) around the endoscope tag R / W 51 so that the washing tank 14 It is prevented from flowing into.

  Further, the endoscope tag R / W 51 is provided on the inclined surface 37b, and a water-repellent coating is applied to the surfaces of the inclined surface 37b and the fitting portion 52a, and dry air is blown, so that the surface of the fitting portion 52a is applied. The treatment liquid (moisture) can be completely removed. Thereby, even when the R / W 51 for the endoscope tag is provided in the cleaning tank 14, the performance of the R / W 51 for the endoscope tag is lowered (the R / W 51 for the endoscope tag and the endoscope tag 48 are It is prevented that the communication range is drastically reduced.

  Next, the cleaning apparatus 75 according to the second embodiment of the present invention will be described with reference to FIG. In the cleaning device 10 of the first embodiment, the device body 13 is provided with the card tag reader 22, and the operator ID is acquired from the card tag 24 by the card tag reader 22. On the other hand, in the cleaning device 75, the shared reader / writer (R / W) 77 of the shared R / W unit 76 provided in the cleaning tank 14 is used to (a) acquire the operator ID, and (b) set the endoscope ID. All of acquisition and (c) writing of cleaning / disinfection result information are performed.

  Since the cleaning device 75 has the same configuration as the cleaning device 10 of the first embodiment except for the shared R / W unit 76 and the lid 78, the same configuration as that of the first embodiment is described with reference to FIGS. Please refer.

  The shared R / W unit 76 has basically the same configuration as the R / W unit 49 of the first embodiment, and includes a holding member 52 and a shared R / W 77. Further, the holding member 52 and the common R / W 77 are attached to the inclined surface 37b and the holding member 52, respectively, by the same mounting structure as that of the first embodiment.

  The shared R / W 77 is basically the same as the R / W 51 for the endoscope tag of the first embodiment. In addition to the acquisition of the endoscope ID and the writing of the cleaning / disinfecting result information, the operator ID is used. Is also acquired. Therefore, the card tag 79 of the ID card 23 transmits an operator ID when receiving an ID request transmitted from the shared R / W 77, and the shared R / W 77 receives an operator ID transmitted from the card tag 79. .

  When the operator ID is acquired by the shared R / W 77, if the ID card 23 is placed in the cleaning tank 14, especially when the endoscope 12 is set in the cleaning tank 14 first, the ID card 23 May accidentally contact the endoscope 12 and the ID card 23 may be contaminated. Further, when the shared R / W 77 is contaminated, if the ID card 23 is brought into contact with the shared R / W 77, the ID card 23 is also contaminated. For this reason, in the second embodiment, the material and shape of the lid 78 are determined so that the operator ID can be acquired by the shared R / W 77 even when the lid 78 is closed.

  On the surface (upper surface) of the card contact surface 80a, a mark or the like (not shown) indicating the set position / posture of the ID card 23 is formed. Further, the card contact surface 80a is formed to be thinner than other portions of the card setting portion 80 so that radio waves can be easily transmitted.

  When the operator brings the ID card 23 into contact with the card contact surface 80a, the distance between the card tag 79 and the shared R / W 77 is within the communicable distance range, and communication between the two is established. As a result, the shared R / W 77 can obtain the operator ID from the card tag 79 of the ID card 23 even when the lid 78 is closed.

  The operation (acquisition procedure of each ID, etc.) of the cleaning device 75 configured as described above is the same as the operation of the cleaning device 10 of the first embodiment described with reference to FIG. 6, and the “ID card” in FIG. Is simply replaced with “contact the ID card with the card contact surface”, and the description and illustration are omitted.

  In the cleaning device 75 of the second embodiment of the present invention, since the operator ID, the endoscope ID and the like can be acquired by one shared R / W 77, unlike the cleaning device 10 of the first embodiment, There is no need to provide the card tag reader 22. Thereby, the cost of the apparatus can be reduced. In addition, since the lid 78 is formed of a radio wave transmitting material and the card setting portion 80 is formed on the lid 78, the operator ID can be obtained even when the lid 78 is closed. Thereby, contamination of the ID card 23 can be prevented.

  In the second embodiment, the case where all of the lid 78 is formed of a radio wave transmitting material has been described.

Moreover, you may provide in the location where process liquids, such as inner surfaces other than the inner surface 37 of the washing tank 14, are easy to flow down (it is hard to stay). In this case, the shape and length of the drying nozzle 42 are appropriately changed so that the drying air can be blown onto the R / W units 49 and 76. Further, the holding member 52 may hold the R / Ws 51 and 77 inside the cleaning tank 14 instead of holding them outside the cleaning tank 14.

  In each of the above embodiments, each R / W 51, 77 acquires the endoscope ID from the endoscope tag 48 and writes the cleaning / disinfecting result information to the endoscope tag 48. However, the present invention is not limited to this, and a tag reader may be provided in place of each of the R / Ws 51 and 77 to obtain only the ID.

  In each of the above embodiments, the drying air is blown onto the surface or the like of the fitting portion 52a after the end of the cleaning process, but the present invention is not limited to this, and even before acquiring the endoscope ID. You can go. Further, not only the drying air is blown from the drying nozzle 42 onto the surface of the fitting portion 52a, but also the water on the surface of the fitting portion 52a may be removed by blowing alcohol.
