  The present invention relates to an endoscope reprocessing device history management system for managing processing histories of a plurality of reprocessing devices that perform reprocessing processing on an endoscope.

  In medical institutions, medical diagnosis using an endoscope is actively performed. Endoscopes used in medical diagnosis are subjected to a cleaning process by a reprocessing apparatus for endoscopes, for example, a cleaning apparatus, in order to prevent disease infection.

When cleaning is performed using a cleaning device, the history information of the cleaning processing is recorded and recorded in order to grasp the history of the cleaning processing, which endoscope was cleaned with which cleaning device. Management is performed. For example, in the cleaning history management system described in Patent Document 1, a passive RFID tag (passive tag) is provided in each of an endoscope, an operator, and a reprocessing apparatus, and an endoscope ID, The reprocessing apparatus ID is acquired and the cleaning history is managed.
JP 2001-327459 A (Patent No. 3854035)

  By the way, when managing the cleaning histories of a plurality of cleaning devices at once using the management system described in Patent Document 1, the cleaning device and the endoscope inserted therein are surely specified. Therefore, it is necessary to provide each reader with a tag reader. This complicates the configuration of the cleaning history management system and may increase the cost of the system.

  In addition, there are many types of cleaning apparatuses, and the presence / absence of a function for outputting history information and the history output method differ depending on each model. The management system described in Patent Document 1 performs history management on the premise of a cleaning apparatus having a function of outputting history information, and in order to manage the history of a cleaning apparatus that does not have such a function, Major modifications must be made, resulting in a significant cost burden. In addition, there are models that cannot be modified depending on the cleaning device, in which case they cannot be managed by the management system. In the medical field, there are many cases where a plurality of cleaning devices of different models coexist, and a countermeasure for reducing the cost burden of these histories has been demanded.

  The present invention has been made to solve the above problem, and provides an endoscope reprocessing device history management system capable of managing processing histories of a plurality of reprocessing devices of different models at low cost. With the goal.

  In order to solve the above problem, the present invention provides an endoscope reprocessing apparatus history management system for managing processing histories of a plurality of reprocessing apparatuses that perform a reprocessing process on a used endoscope. The position of the endoscope based on at least three tag readers that read the ID information of the endoscope from the active first RFID tag provided on the endoscope, and the reading result of the ID information of the endoscope by the tag reader A position detection means for detecting the position, a reprocessing apparatus specification means for specifying the reprocessing apparatus to which the endoscope is inserted based on a position detection result of the position detection means, and a specification by the reprocessing apparatus specification means Acquisition method determining means for determining an acquisition method for acquiring the processing history from the reprocessed device, and an acquisition method determined by the acquisition method determining means In, characterized in that from the reprocessing device and a history acquisition means for acquiring the processing history. The reprocessing process is a process for making a used endoscope reusable, and includes at least one of a cleaning process, a disinfection process, and a sterilization process.

  The acquisition method determination means preferably determines the acquisition method with reference to an acquisition method table in which information related to the acquisition method for each reprocessing apparatus is stored in advance.

  It is preferable that the processing history of each reprocessing device acquired by the history acquisition unit is provided with a recording format conversion unit that converts the processing history into a unified recording format. By unifying the recording format, it is possible to collectively manage the processing history of each reprocessing apparatus in one history table or the like.

  The acquisition method includes a first acquisition method in which the processing history is acquired through the second RFID tag and the tag reader from a reprocess device having an active second RFID tag that stores ID information of the reprocess device. It is preferable that As a result, the processing history can be acquired from the reprocessing apparatus without making significant modifications to the reprocessing apparatus.

  In the first acquisition method, the supply / discharge state of the liquid supplied / discharged to the processing tank of the reprocessing apparatus is recorded on the second RFID tag, and the tag reader reads the supply / discharge liquid state, thereby It is preferable that a processing history of the process device is acquired.

  It is preferable that the acquisition method includes a second acquisition method for acquiring the processing history through communication between the first RFID tag and the tag reader. As a result, the processing history can be acquired from the reprocessing apparatus without any modification to the reprocessing apparatus.

  In the second acquisition method, communication between the first RFID tag and the tag reader is monitored, and communication with the tag reader is disabled when the first RFID tag is immersed in the liquid in the processing tank. Preferably, the processing history is acquired by detecting the supply / discharge state of the liquid.

  The acquisition method preferably includes a third acquisition method in which the processing history recorded by the reprocess device is acquired by communicating with the reprocess device without going through the tag reader.

  The history management system of the endoscope reprocessing apparatus according to the present invention detects the position of the endoscope based on the reading result of the tag reader that reads the ID information from the first RFID tag of the endoscope, and based on the position detection result. The acquisition method for acquiring the processing history from the reprocessing device identified as having the endoscope inserted is determined, and the processing history is acquired and managed from the reprocessing device using the determined acquisition method. Even when a plurality of reprocess devices coexist, the processing history of each reprocess device can be collectively managed at a low cost. In addition, even with a reprocessing apparatus that does not have a processing history output function, processing history can be acquired and managed without significant or no modification.

  The cleaning system (reprocessing apparatus history management system) 9 shown in FIG. 1 is roughly divided into a management server 10, tag readers 12 a to 12 c for communicating with the endoscope 11, and cleaning for cleaning the endoscope 11. The apparatus (reprocessing apparatus) 13a-13c is comprised. In this embodiment, the example of three cleaning devices is described, but any number of cleaning devices may be used as long as the number is two or more.

  The cleaning system 9 (management server 10) specifies the cleaning device in which the endoscope 11 is inserted from the cleaning devices 13a to 13c through the tag readers 12a to 12c, and stores the cleaning history corresponding to the specified cleaning device. By determining the acquisition method and acquiring the cleaning history based on the determined acquisition method, the cleaning history of each of the cleaning apparatuses 13a to 13c is managed. The cleaning history includes, for example, the date of the cleaning process, the start time and the end time, the endoscope ID of the endoscope 11 on which the cleaning process has been performed, and the device ID of the cleaning apparatus that has performed the cleaning process.

  The tag readers 12a to 12c are installed in, for example, a cleaning room, and the cleaning devices 13a to 13c are installed within a communicable range of the tag readers 12a to 12c. The tag readers 12a to 12c are connected to the management server 10 via the LAN 14, respectively. The tag readers 12a to 12c transmit ID transmission requests (hereinafter referred to as ID requests) at regular intervals, and are transmitted from the endoscope ID transmitted from the endoscope 11 and the cleaning device 13a in response to the ID request. Device ID is received.

  The endoscope 11 is provided with an endoscope tag 16 (first RFID tag). The endoscope tag 16 is an active RFID tag (active tag). Unlike the passive tag, the active tag operates with electric power supplied from a battery (not shown). Therefore, the endoscope tag 16 is at a distance of about several tens of meters from the tag readers 12a to 12c (the passive tag is about several tens of centimeters). Communication is possible. The endoscope tag 16 is provided with an antenna 16a and a memory 16b that stores an endoscope ID (see FIGS. 2 to 4). The endoscope tag 16 transmits a radio wave on which the endoscope ID is superimposed from the antenna 16a.

  As shown in FIGS. 2 to 4, the cleaning apparatuses 13 a to 13 c have different models, and the models A to C in the drawings are model names. The number of types of models is not particularly limited. Models A and B do not have a function of recording their own cleaning history information (hereinafter referred to as individual cleaning history information), and model C has a function of recording individual cleaning history information. The individual cleaning history information includes a cleaning process date, start time, and end time. In addition, since endoscope ID is acquired through the tag readers 12a to 12c, it is not included in the individual cleaning history information in this embodiment.

  Regardless of the model, each of the cleaning devices 13a to 13c includes a cleaning tank 18 provided at the top of the device body 17, and an operation panel 19 provided with a power switch, a start switch, and the like. In addition, No001-No003 described in FIG. 1 is apparatus ID of each washing | cleaning apparatus 13a-13c.

  The endoscope used in the inspection is set in the cleaning tank 18 and subjected to a cleaning process. The cleaning process is roughly divided into cleaning, disinfection, and rinsing processes. In each step, a cleaning treatment liquid 18a (see FIG. 7) such as a cleaning liquid, a disinfecting liquid, and water is supplied to the cleaning tank 18. These cleaning treatment liquids 18a are not only supplied into the cleaning tank 18, but also supplied into the channel of the endoscope 11 through a liquid supply port (not shown).

  A device tag 20 (second RFID tag) is provided on the upper portion of the cleaning device 13a. The device tag 20 is an active tag, similar to the endoscope tag 16, and includes an antenna 20a and a memory 20b that stores device IDs, and device IDs are assigned in response to ID requests from the tag readers 12a to 12c. The superimposed radio wave is transmitted from the antenna 20a. The device tag 20 is connected to a water level detection sensor 22 in the cleaning tank 18 via a CPU 21 that controls each part of the cleaning device 13a. As a result, the viewing result by the water level detection sensor 22 is output (recorded) to the device tag 20.

  The water level detection sensor 22 detects whether or not the water level in the cleaning tank 18 has reached a water level L (see FIG. 7) at which the cleaning process can be performed. The water level detection sensor 22 is turned off when the water level L has not been reached, is turned on when it has been detected that the water level L has been reached, and outputs a water level detection signal to the device tag 20 via the CPU 21. When the water level detection signal is input from the water level detection sensor 22, the device tag 20 transmits a radio wave superimposed with the water level detection signal together with the device ID from the antenna 20a.

  Although the cleaning device 13b is not shown in the drawing, a water level detection sensor (not shown) for detecting the water level of the cleaning layer 18 is provided as standard as in the cleaning device 13a, but a device corresponding to the device tag 20 is provided. It is not done. Therefore, the water level detection signal is not transmitted from the cleaning device 13b.

  The cleaning device 13 c includes a LAN interface 23 connected to the LAN 14 and is connected to the management server 10 via the LAN. The CPU 21 of the cleaning device 13 c functions as the individual history recording unit 25 and the individual history output unit 26 based on the program read from the storage 24. In addition, the communication interface which connects the washing | cleaning apparatus 13c and the management server 10 is not specifically limited, Various communication interfaces can be used.

  The individual history recording unit 25 includes a clock circuit (not shown), and records individual cleaning history information (cleaning process date, start time, and end time) of the cleaning process performed by the cleaning device 13c. The date can be obtained by an appropriate method such as obtaining from the above-described clock circuit or the like. Further, the start time and the end time can be acquired, for example, by monitoring the control status of each part of the cleaning device 13c by the CPU 21. The individual cleaning history information acquired by the individual history recording unit 25 is recorded in the individual history table 28 of the storage 24.

  In the individual history table 28, an individual history record 28a representing individual cleaning history information is recorded. The individual history record 28 a is provided with fields for recording the date, start time, and end time acquired by the individual history recording unit 25. In each field, the date, start time, and end time output from the individual history recording unit 25 are sequentially recorded.

  The individual history output unit 26 receives a cleaning history information distribution request (hereinafter referred to as a history request) from the management server 10 via the LAN 14 and responds to the latest individual history record 28 a in the individual history table 28. The recorded individual cleaning history information is output to the management server 10 via the LAN 14. When the individual history output unit 26 outputs the individual cleaning history information, the individual history output unit 26 does not output the information already output in response to the previous history request, and newly outputs the individual history record after the previous history request. Only the information recorded in each field 28 a is output to the management server 10.

  Returning to FIG. 1, each tag reader 12a-12c is provided with an antenna 29a and a detection circuit 29b (not shown in the tag readers 12a and 12b). The detection circuit 29b detects the intensity of radio waves from the tags 16 and 20 received by the antenna 29a. The detection circuit 29b outputs the detection result to the management server 10. The radio wave intensity can be obtained, for example, from a DC voltage obtained by detecting a radio signal received by the antenna 29a, rectifying the detected signal, and further integrating the rectified signal. Note that the detection method of the radio wave intensity is not limited to this, and various known methods can be used.

  As a method of distinguishing radio waves transmitted from the endoscope tag 16 and the device tag 20 when detecting the radio field intensity, for example, tag readers 12a to 12c having an anti-collision function and the tags 16 and 20 are used. There is a way. Further, for example, the frequency of the radio wave transmitted from each of the tags 16 and 20 may be varied, and the radio wave intensity may be detected for each frequency.

  As shown in FIG. 5, the management server 10 is provided with a console 30, a CPU 31, a storage 32, and a LAN port 33 for connecting to the LAN 14, which are connected to each other via a data bus 34. Has been. The console 30 includes input devices and a monitor. The input device is a known input device such as a mouse or a keyboard.

  The CPU 31 performs overall control of each unit of the management server 10 by sequentially executing various programs read from the storage 32 or a memory (not shown). The storage 27 stores a master data area in which data used for specifying the cleaning device into which the endoscope 11 is inserted and data used for determination of an acquisition method for acquiring cleaning history information from each of the cleaning devices 13a to 13c are stored. And a transaction data area used for recording and managing cleaning history information acquired from each of the cleaning apparatuses 13a to 13c.

  The CPU 31 executes the above-described program, thereby causing the reader control unit 35, the position detection unit (position detection unit) 36, the cleaning device identification unit (reprocess device identification unit) 37, and the acquisition method determination unit (acquisition method determination unit). 38, a history acquisition unit (history acquisition unit) 39, and a history recording unit (recording format conversion unit) 40.

  The reader controller 35 controls transmission / reception of various information by the tag readers 12a to 12c. The reader controller 35 transmits an ID request from the tag readers 12a to 12c at a constant cycle. Thereby, the IDs of all the tags 16 and 20 within the communication range of the tag readers 12a to 12c are acquired by the tag readers 12a to 12c, and the intensity of the radio waves from the tags 16 and 20 at the time of acquiring the ID is It is detected by the detection circuit 29 b and input to the position detection unit 36 of the management server 10.

  The position detection unit 36 detects the position of the endoscope 11 and the cleaning device 13 a (model A) including the device tag 20. Both positions are detected based on the detection results of the intensity of the radio waves from the tags 16 and 20 detected by the detection circuits 29b of the tag readers 12a to 12c.

  The position detector 36 calculates the distances between the individual tag readers 12a to 12c and the endoscope 11 and the cleaning device 13a based on the detection results of the radio wave intensity from the tags 16 and 20. The distance between each of these can be obtained from the detection result of the radio wave intensity, for example, by previously obtaining the relationship between the distance between each and the radio wave intensity. Then, the position detection unit 36 performs, for example, three-point measurement or position correction based on the obtained distances and the positions of the known tag readers 12a to 12c to determine the positions of the endoscope 11 and the cleaning device 13a. To detect. Since the method for detecting the position by three-point surveying or the like is well known, the description thereof is omitted. Further, although three reader / writers are sufficient for three-point surveying, four or more reader / writers may be used to improve the accuracy of position detection.

  Since ID requests are transmitted from the tag readers 12a to 12c at a constant cycle, the position detection unit 36 also detects the positions of the endoscope 11 and the cleaning device 13a at regular intervals. These position detection results are output to the cleaning device specifying unit 37 for each detection. Unlike the endoscope 11, the cleaning device 13a does not move because it is installed and fixed at a predetermined position. Accordingly, the position detection unit 36 stores the position detection result of the cleaning device 13a in the storage 32 or the like, and thereafter discards the detection result of the radio wave intensity from the cleaning device 13a input from the detection circuit 29b. Thereby, the load concerning the position detection process by the position detection part 36 (CPU31) can be reduced.

  The cleaning device specifying unit 37 performs the cleaning in which the endoscope 11 has been inserted based on the position detection results of the endoscope 11 and the cleaning device 13a and the position information storage table 42 stored in the master data area of the storage 32. Identify the device. In the position information storage table 42, the position information of the cleaning devices 13b and 13c is stored in advance in association with the corresponding device ID. The cleaning device specifying unit 37 detects the insertion of the endoscope 11 into the cleaning device based on whether or not the position of the endoscope 11 substantially coincides with any one of the cleaning devices 13a to 13c. Then, the cleaning device in which the endoscope 11 is inserted is specified. The determination as to whether or not the endoscope 11 and the positions of the cleaning devices 13a to 13c coincide with each other is performed, for example, by examining whether or not the endoscope 11 exists within a radius Xcm from the cleaning device. Is called. Here, the radius Xcm is set to a size that does not interfere with an adjacent cleaning device, for example. Hereinafter, an example of the specific process of the cleaning apparatus will be described with reference to FIG.

  Since the ID requests are transmitted from the tag readers 12a to 12c at regular intervals, radio waves transmitted from the tags 16 and 20 in response to the ID requests are received at regular intervals by the tag readers 12a to 12c. Thereby, as described above, the position detection unit 36 detects the positions of the endoscope 11 and the cleaning device 13a. The position detection result of the cleaning device 13a is recorded in the storage 32 or the like.

  When the endoscope 11 is inserted into the cleaning device 13a (model A), the position of the endoscope 11 detected by the position detection unit 36 and the position of the cleaning device 13a substantially coincide with each other. Thereby, it can be specified that the endoscope 11 has been put into the cleaning device 13a.

  When the endoscope 11 is inserted into the cleaning device 13b, the position of the endoscope 11 detected by the position detection unit 36 and the position of the cleaning device 13b stored in the position information storage table 42 Can be identified as having been inserted into the cleaning device 13b. Similarly, when the endoscope 11 is put into the cleaning device 13c, it can be specified that the endoscope 11 is put into the cleaning device 13c.

  When the endoscope 11 is not put in any of the cleaning devices 13a to 13b, the position of the endoscope 11 and the positions of the cleaning devices 13a to 13c are different. It is determined that the endoscope 11 is not put into the cleaning device. Hereinafter, the position detection of the endoscope 11 is performed at regular intervals in response to ID requests transmitted from the tag readers 12a to 12c at regular intervals, and the above-described processing is repeated. Since the position detection result of the cleaning device 13a has already been recorded in the storage 32 or the like, if the position detection process of the cleaning device 13a is performed only once, it will not be performed after the next time.

  Returning to FIG. 5, the identification result by the cleaning device identification unit 37 is input to the acquisition method determination unit 38. The acquisition method determination unit 38 refers to the acquisition method table 44 stored in the master data area of the storage 32 and determines an acquisition method for acquiring cleaning history information from the cleaning device specified by the cleaning device specification unit 37. . In the acquisition method table 44, acquisition methods A1 to C1 predetermined for each of the cleaning devices 13a to 13c (models) are stored in association with the corresponding device IDs. The history acquisition unit 39 acquires the cleaning history information from the cleaning device according to the acquisition method determined by the acquisition method determination unit 38.

  The acquisition method A1 is an acquisition method corresponding to the cleaning device 13a (model A) having a function of outputting a water level detection signal by the water level detection sensor 22, and acquires cleaning history information through the device tag 20 and the tag readers 12a to 12c. Is. The acquisition method B1 is an acquisition method corresponding to the cleaning device 13b (model B) that does not have the output function of the water level detection signal, and the cleaning history is based on the communication state between the endoscope tag 16 and the tag readers 12a to 12c. Information is acquired. The acquisition method C1 is an acquisition method corresponding to the cleaning device 13c (model C) having a function of recording individual cleaning history information, and acquires the cleaning history information through the LAN 14 without passing through the tag readers 12a to 12c. It is.

  First, the process in which the history acquisition unit 39 acquires the cleaning history information of the cleaning device 13a by the acquisition method A1 will be described with reference to FIGS. The date of the cleaning process is acquired by an appropriate method, for example, from a clock circuit (not shown) of the CPU 31. For the endoscope ID and the device ID, the reader control unit 35 is controlled to acquire only the ID of the acquisition source specified from the IDs received by the tag readers 12a to 12c.

  In the acquisition method A1, the start and end times of the cleaning process are acquired based on the water level detection signal transmitted from the cleaning device 13a. As described above, in response to the ID requests transmitted from the tag readers 12a to 12c, radio waves (ID) transmitted from the endoscope tag 16 and the device tag 20 of the cleaning device 13a are received by the tag readers 12a to 12c. The

  When the endoscope 11 is put into the cleaning device 13a and the cleaning process is started by the cleaning device 13a, the cleaning process liquid 18a used in the first process of the cleaning process is supplied into the cleaning tank 18. When the water level in the cleaning tank 18 reaches the above-described water level L, an initial water level detection signal is output from the water level detection sensor 22 to the device tag 20 (see FIG. 8). As described above, the water level detection signal is transmitted by radio waves from the device tag 20 to the tag readers 12a to 12c, and is input to the management server 10 from the tag readers 12a to 12c via the LAN.

  When the first water level detection signal is input to the management server 10, it can be determined that the cleaning process is started by the cleaning device 13a. Accordingly, the history acquisition unit 39 acquires the time when the water level detection signal is first received from the cleaning device 13a, that is, the time when the water level of the cleaning tank 18 first reaches the water level L as the start time of the cleaning process.

  The end time of the cleaning process is obtained by measuring the time until the next liquid supply is performed after draining the cleaning process liquid 18a from the cleaning tank 18 by the timer circuit 45 shown in FIG. When each process of the cleaning process is executed in sequence, the supply and discharge liquid of the cleaning process liquid 18a is repeatedly performed. Thereby, since the output of the water level detection signal from the water level detection sensor 22 is turned ON / OFF, the input / input stop of the water level detection signal from the cleaning device 13a to the management server 10 is repeated.

  When one cleaning process is completed, another endoscope 11 is set in the cleaning device 13a, and the supply of the cleaning process liquid 18a is not performed until the next cleaning process is started. For this reason, when the cleaning process is completed, the water level detection signal is not input to the management server 10. Therefore, when the cleaning process is started in the cleaning device 13a, the history acquisition unit 39 activates the timer circuit 45 of the CPU 31 and measures the input stop time of the water level detection signal from the cleaning device 13a to the management server 10.

  When the measurement time by the timer circuit 45 exceeds a predetermined time, the history acquisition unit 39 determines that the cleaning process by the cleaning device 13a has ended, and acquires the end time of the cleaning process. This fixed time is set longer than the water supply / drainage process performed between each process of a washing process. The end time is a time obtained by subtracting the above-described fixed time from the time when it is determined that the cleaning process has ended. In addition, when the drying process which does not use the cleaning liquid 18a is included in each process of the cleaning process, for example, it is determined whether the drying process is performed using a temperature sensor or the like, and the drying process is performed. While being executed, the measurement by the timer circuit 45 may be stopped. As described above, in the acquisition method A1, in addition to the above-described date and both IDs, the water level detection sensor 22 detects the supply / drainage state of the cleaning process 18a in the cleaning tank 18 to thereby determine the start and end times of the cleaning process. get. Thereby, all the cleaning history information of the cleaning device 13a is acquired.

  Next, the process in which the history acquisition unit 39 acquires the cleaning history information of the cleaning device 13b by the acquisition method B1 will be described with reference to FIGS. 9 and 10A and 10B. The date of the cleaning process and the endoscope ID are acquired by the method described in the acquisition method A1. Further, the device ID can be acquired from the IDs stored in the position information storage table 42 and the acquisition method table 44.

  In the acquisition method B1, the start and end times of the cleaning process are acquired based on the communication state between the endoscope 11 (endoscope tag 16) set in the cleaning device 13b and the tag readers 12a to 12c. When the endoscope 11 is inserted into the cleaning device 13b, radio waves transmitted from the endoscope tag 16 in response to ID requests from the tag readers 12a to 12c are received by the tag readers 12a to 12c, respectively (see FIG. 10 (A)). Next, when the cleaning process is started and at least when the water level in the cleaning tank 18 reaches the water level L, the endoscope 11 is completely immersed in the cleaning process liquid 18a.

  When the endoscope 11 and the endoscope tag 16 are completely immersed in the cleaning treatment liquid 18a, the ID requests transmitted from the tag readers 12a to 12c are not transmitted to the endoscope tag 16 in the liquid. Communication between the tag 16 and each of the tag readers 12a to 12c is interrupted (see FIG. 10B). Therefore, whether or not the endoscope 11 is immersed in the cleaning treatment liquid 18a can be detected based on whether or not communication with the endoscope tag 16 is interrupted.

  At this time, since the water level L described above and the water level at which the endoscope 11 is completely immersed in the cleaning liquid 18a are substantially the same, in the acquisition method B1, the tag readers 12a to 12c and the endoscope tag 16 Whether the water level in the cleaning tank 18 has reached the water level L is determined based on whether or not the communication is interrupted. That is, in the acquisition method B1, the endoscope tag 16 is used as a substitute for the water level detection sensor 22 and the device tag 20.

  When the communication between the endoscope tag 16 and each of the tag readers 12a to 12c is interrupted, the history acquisition unit 39 determines that the cleaning process has been started and acquires the start time. And if each process of a washing process is performed in order, supply and drainage of washing process liquid 18a will be performed repeatedly, therefore transmission of an electric wave (endoscope ID) from endoscope 11 (endoscope tag 16). Is turned ON / OFF.

  When one cleaning process is completed, the supply of the cleaning process liquid 18a is not performed until the next cleaning process is started, and communication between the two continues. Therefore, when the history acquisition unit 39 acquires the start time of the cleaning process, the timer circuit 45 measures the communication time between the two, and the cleaning process ends when the communication time exceeds a predetermined time. Determine and obtain the end time. Thereby, all the cleaning history information of the cleaning device 13b is acquired.

  Next, an acquisition process in which the history acquisition unit 39 acquires the cleaning history information of the cleaning device 13c by the acquisition method C1 will be described with reference to FIG. The endoscope ID and the device ID are acquired by the method described in the acquisition methods A1 and B1 described above.

  In the acquisition method C1, the date, start time, and end time of the cleaning process are directly acquired from the cleaning device 13c. As described above, the cleaning device 13c outputs the individual cleaning history information (date, start time, and end time) to the management server 10 in response to the history request. Accordingly, when it is determined that the acquisition method of the cleaning history information from the cleaning device 13c is the acquisition method C1, the history acquisition unit 39 distributes the history request to the cleaning device 13c at a constant cycle via the LAN 14.

  The history request includes data representing the device ID of the cleaning device 13c. The individual history output unit 26 (see FIG. 4) of the cleaning device 13c outputs the individual cleaning history information when the device ID included in the history request received via the LAN 14 matches the device ID of the cleaning device 13c. . Accordingly, the history acquisition unit 39 can acquire all the cleaning history information of the cleaning device 13c by acquiring the date, start time, and end time of the cleaning process in addition to the above-described both IDs. The history acquisition unit 39 stops the distribution of the history request after acquiring the end time of the cleaning process.

  Returning to FIG. 5, the cleaning history information acquired from each of the cleaning apparatuses 13a to 13c in each of the acquisition methods A1 to C1 is sequentially output to the history recording unit 40 in the acquisition order. The history recording unit 40 records the cleaning history information acquired from each of the cleaning apparatuses 13 a to 13 c in a unified recording format in the cleaning history table 47 stored in the transaction data area of the storage 32.

  In the cleaning history table 47, a cleaning history record 47a representing cleaning history information is recorded. The cleaning history record 47 a is created in association with the apparatus ID output from the history acquisition unit 39 to the history recording unit 40. The cleaning history record 47a is provided with fields for recording date, start and end times, and endoscope ID. In each field, the date, start and end times, and endoscope ID output from the history acquisition unit 39 are sequentially recorded. The history recording unit 40 converts the acquired cleaning history information into the recording format (the format of each field and the storage format) of the cleaning history record 47a and records it. Thereby, the cleaning history information of each of the cleaning apparatuses 13a to 13c acquired by the different acquisition methods A1 to C1 is recorded in the cleaning history table 47 in a unified recording format.

  Next, the operation of the cleaning system 9 will be described with reference to FIG. When the endoscope 11 is inserted into any of the cleaning devices, as described with reference to FIG. 6 above, detection of the insertion of the endoscope 11 into the cleaning device and the cleaning device into which the endoscope 11 has been inserted.

  The acquisition method determination unit 38 of the management server 10 refers to the acquisition method table 44 and acquires the acquisition method when the cleaning device into which the endoscope 11 is inserted is identified as the cleaning device 13a (model A). A1 is determined as a method for acquiring cleaning history information. This determination result is output to the history acquisition unit 39. As described above with reference to FIG. 7, the history acquisition unit 39 acquires the cleaning history information from the cleaning device 13a by the acquisition method A1, and outputs the acquired cleaning history information to the history recording unit 40.

  In addition, the acquisition method determination unit 38 determines that the acquisition method B1 is the acquisition method of the cleaning history information when the cleaning device in which the endoscope 11 is inserted is identified as the cleaning device 13b (model B). . As described above with reference to FIG. 9, the history acquisition unit 39 acquires the cleaning history information from the cleaning device 13 b by the acquisition method B <b> 1, and outputs the acquired cleaning history information to the history recording unit 40.

  In addition, when the cleaning device into which the endoscope 11 is inserted is identified as the cleaning device 13c (model C), the acquisition method determination unit 38 determines the acquisition method C1 as the method for acquiring the cleaning history information. . As described above with reference to FIG. 11, the history acquisition unit 39 acquires the cleaning history information from the cleaning device 13 c by the acquisition method C <b> 1 and outputs the acquired cleaning history information to the history recording unit 40.

  The history recording unit 40 creates a cleaning history record 47a corresponding to the apparatus ID of the cleaning device input from the history acquisition unit 39 in the cleaning history table 47, and inputs the fields of the cleaning history record 47a from the history acquisition unit 39. The recorded date, start and end time, and endoscope ID are recorded. Thereby, the cleaning history information of each of the cleaning apparatuses 13a to 13c acquired by the different acquisition methods A1 to C1 is recorded in the cleaning history table 47 in a unified recording format. Accordingly, the cleaning history of the cleaning apparatuses 13 a to 13 c of different models can be collectively managed by the cleaning history table 47.

  As described above, in the cleaning system 9 of the present invention, the three tag readers 12a to 12c are arranged at different positions to specify the cleaning device in which the endoscope 11 is inserted, and acquire the cleaning history from the specified cleaning device. Since the acquisition method is determined and the cleaning history of the cleaning device is acquired using the determined acquisition method, the cleaning history of each cleaning device can be reduced at a low cost even when multiple cleaning devices of different models are mixed. Can be managed.

  Further, in the present invention, even if the cleaning device does not have a cleaning history output function, a detailed cleaning history including the start time and end time of the cleaning process can be acquired without making a major modification. Can do. For example, when using the water level detection sensor that is provided as standard in the cleaning device, add a device tag and remodel the water level detection sensor so that a water level detection signal is output to the device tag (see Model A). . When the standard water level detection sensor is not used, an apparatus tag and a water level detection sensor having a function of outputting a water level detection signal to the apparatus tag are attached to the cleaning tank. In any case, it is possible to make a small modification as compared with the case where a communication I / F using LAN and a history output program are provided in the cleaning device.

  Furthermore, in the present invention, at least an endoscope is provided with an endoscope tag, and the communication state between the endoscope tag and each tag reader is monitored, so that the cleaning apparatus having no cleaning history output function is provided. The detailed cleaning history can be acquired without any modification (see Model B). As a result, the system can be configured more simply and inexpensively.

  The cleaning apparatus 13c (model C) of the above embodiment has been described by taking as an example an apparatus that employs a history output method that outputs individual cleaning history information to the management server 10 in response to a history request. However, the present invention is not limited to this, and may be a device that adopts another history output method. For example, as the cleaning device 13c, the individual history recording unit 25 records the individual cleaning history information, and at the same time, the individual cleaning history information recorded by the individual history output unit 26 is automatically updated without waiting for a history request. An apparatus that adopts a history output method for outputting to the terminal may be used. In addition, a plurality of cleaning devices adopting different history output methods may be LAN-connected to the management server 10.

  Further, in the above-described embodiment, the case where the endoscope ID is not included in the individual cleaning history information acquired by the individual history recording unit 25 of the cleaning device 13c has been described as an example.

For example, a tag reader (hereinafter referred to as a device tag reader) is provided in the device main body 17 of the cleaning device 13c, the endoscope ID of the endoscope 11 set in the cleaning device 13c is acquired through the device tag reader, and the individual history table 28 is obtained. You may make it record. Specifically, when the endoscope 11 is set in the cleaning device 13c, the distance of the endoscope 11 from the device tag reader becomes the shortest. For this reason, since the reception intensity of the radio wave received by the device tag reader from the endoscope 11 set in the cleaning device 13c is the highest, the endoscope 11 set in the cleaning device 13c is specified, and the endoscope The ID can be recorded in the individual history table 28.

  In the above-described embodiment, the distance between the tag readers 12a to 12c, the endoscope 11 and the cleaning device 13a is calculated based on the intensity of radio waves transmitted from the tags 16 and 20, and the endoscope 11 is calculated. However, the present invention is not limited to this. For example, based on the arrival time at which radio waves transmitted from the tags 16 and 20 reach the tag readers 12a to 12c, the distance between them may be calculated to detect the position of the endoscope or the like. . The arrival time of the radio wave is obtained, for example, by measuring the time from when the ID request is transmitted until the radio wave transmitted from each of the tags 16 and 20 is received by each of the tag readers 12a to 12c.

  Moreover, in the said embodiment, the case where the water level detection sensor which detects the water level in the washing tank 18 is used as an example as a supply / drain liquid detection means which detects the supply / drain liquid of the cleaning process liquid 18a in the washing tank 18 is mentioned as an example.
