  In a medical facility, an endoscope is managed by status information indicating its state. The user sets the status of “in repair” in the endoscope sent for repair, and sets the status of “discarded” in the discarded endoscope. In this way, in a medical facility, an endoscope that is currently in a non-usable state (non-operating state) is distinguished from an endoscope that is in a usable state (operating state).

  However, the status change from the operating status to the non-operating status is usually performed manually by the user, and the status may not be properly updated due to a forgotten input or the like. In the case of loss or misuse of the endoscope, the user can not recognize that the endoscope is not in operation, so there is no opportunity to input a status change, and the status is hard to be updated. Therefore, when displaying the endoscopes owned by the facility in a list together with the status information, the endoscope is displayed together with the status information indicating that the endoscope is in the operating condition even though the endoscope is not available in the facility. Can occur. Therefore, it is desired to develop a technique for examining the possibility of being in the non-operating state even if the endoscope is set with the status information of the operating state.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a technique for managing an endoscope in a facility.

  The status management unit 24 performs "in use in inspection" (ST1), "in use in inspection" (ST2), "in washing" (ST3), "cleaned" (ST4), and "in storage" (ST5) of the endoscope. It manages by eight status information of "under repair" (ST6), "during lending" (ST7), and "discarded" (ST8). In FIG. 2, the managed status enables transition to the direction specified by the direction of the arrow.

  “Investigation in use” indicates that the endoscope is connected to the observation device 3 and is in use. “Inspection used” indicates a state in which the endoscope has been removed from the observation device 3 after the endoscopy. "During cleaning" indicates that the endoscope is attached to the cleaning tank of the cleaning device 4 and the cleaning program is started. "Washed" indicates a state in which the washing process of the endoscope has been completed. “During storage” indicates a state in which the cleaned endoscope is stored in the storage 5.

  Five status information of "in use in test" (ST1), "in use in test" (ST2), "in washing" (ST3), "cleaned" (ST4) and "in storage" (ST5) are medical facilities Indicate that the endoscope is ready to use. Hereinafter, the usable state is referred to as the "operating state".

  "Under repair" indicates that the endoscope has failed and is being repaired at the repair center. “Lending” indicates that the endoscope is being rented to another medical facility in response to a request from another medical facility. "Discarded" indicates that the endoscope has been discarded.

  Three status information of "under repair" (ST6), "during lending" (ST7), and "discarded" (ST8) indicate that the endoscope is in an unusable state in the medical facility. Hereinafter, the unusable state is called "non-operating state".

  When the endoscope is connected to the observation device 3 by the nurse before the start of the examination, the observation device 3 acquires the scope ID and model number information of the endoscope. When the examination start button provided on the observation device 3 is operated, the observation device 3 transmits information indicating the start of the examination to the endoscope management device 10 together with the scope ID and the model number information, and the endoscopic examination is performed It is started. During the examination, the observation device 3 displays in real time the image data acquired by the endoscope on the monitor, and acquires the examination image at the timing when the release switch of the endoscope is pressed, and the endoscope management device 10 Send. When the examination end button provided on the observation device 3 is operated, the observation device 3 transmits information indicating the end of the examination to the endoscope management device 10, and the endoscopic examination is completed.

  At the start of the inspection, the acquisition unit 20 acquires the scope ID, the model number information, and the inspection start information, and supplies them to the registration unit 22 and the status management unit 24. At this time, the registration unit 22 links the scope ID to the examination start time in the use history storage unit 64, and the status management unit 24 checks the status information of the endoscope identified by the scope ID “ It is set to "medium" (ST1) and stored in the status storage unit 70.

  During an examination, the acquisition unit 20 acquires examination image data and supplies the examination image data to the registration unit 22. The registration unit 22 stores the examination image data in the examination image storage unit 68.

  At the end of the examination, the acquisition unit 20 acquires examination end information and supplies the information to the registration unit 22 and the status management unit 24. At this time, the registration unit 22 links the scope ID to the inspection end time in the use history storage unit 64, and the status management unit 24 checks the status information of the endoscope specified by the scope ID “ (ST2), and stored in the status storage unit 70.

  When the inspection is completed, the person in charge of cleaning brings the RFID of the endoscope close to the ID reading unit (not shown) disposed in the cleaning device 4 to read the scope ID and the model number information before the start of the cleaning. Thereafter, the person in charge of cleaning sets the endoscope in the cleaning tank of the cleaning device 4, selects the cleaning program for the endoscope, and then operates the cleaning start button to start cleaning. When the washing start button is operated, the washing device 4 transmits the scope ID and the model number information read by the ID reading unit to the endoscope management device 10 together with the washing start information. When the cleaning is completed, the cleaning device 4 automatically transmits the cleaning end information to the endoscope management device 10.

  At the start of cleaning, the acquiring unit 20 acquires the scope ID, the model number information, and the cleaning start information, and supplies them to the registration unit 22 and the status management unit 24. At this time, the registration unit 22 associates the scope start time with the scope ID by registering the start time of cleaning in the cleaning history storage unit 66, and the status management unit 24 checks that the status information of the endoscope specified by the scope ID (ST3) and stores the status in the status storage unit 70.

  At the end of cleaning, the acquisition unit 20 acquires cleaning end information and supplies the information to the registration unit 22 and the status management unit 24. At this time, the registration unit 22 links it to the scope ID, and registers the cleaning end time in the cleaning history storage unit 66, and the status management unit 24 cleans the status information of the endoscope specified by the scope ID. (ST4), and stores it in the status storage unit 70.

  If there is no scheduled inspection use on the day for the endoscope that has been cleaned, the person in charge carries it to the storage room, brings the RFID of the endoscope close to the ID reading unit placed in the storage 5, and the scope ID And, read the model number information and store it in the storage 5. The acquisition unit 20 acquires the scope ID and the model number information from the storage 5 and supplies the scope ID and the model number information to the status management unit 24. The status management unit 24 sets the status information of the endoscope specified by the scope ID to “during storage” (ST5), and stores the status information in the status storage unit 70.

  As described above, the registration unit 22 registers usage information on the use of the endoscope in the usage history storage unit 64, and registers cleaning information on the cleaning of the endoscope in the cleaning history storage unit 66. Therefore, the usage history storage unit 64 accumulates usage information of each endoscope regarding daily inspection, and the cleaning history storage unit 66 accumulates cleaning information of each endoscope regarding daily cleaning.

  The status management unit 24 also manages status information of each endoscope based on the information acquired by the acquisition unit 20. The status of ST1 to ST5 above indicates that the status is "operating status", that is, the endoscope can be used in a medical facility. Information on these statuses is automatically or semi-automatically transmitted from the respective facilities to the endoscope management apparatus 10, so that the status management by the status management unit 24 is surely implemented.

  On the other hand, in the statuses of ST6 to ST8, the user causes the display of the terminal device 6 to display a status change screen, inputs the status change on the change screen, and the status management unit 24 receives the change input from the acquisition unit 20 Managed by Therefore, if the user forgets to input etc., the status update is not properly implemented, and the status of ST2 or ST4 or ST5 which is in the operating state is set despite the endoscope being in the non-operating state. It will remain done.

  FIG. 3 shows an example of the display screen of the endoscope list held by the medical facility. The display processing unit 44 displays the endoscope list screen on the display of the terminal device 6 in response to the user's request. The endoscope list shown in FIG. 3 is shown as a comparative example when the display processing unit 44 creates the status information of each endoscope stored in the status storage unit 70 as it is.

  Status information is displayed in the status column. Information for identifying an endoscope (scope ID) is displayed in the scope ID column. The scope ID may be a serial number. The model number column displays model number information for specifying the type (model) of the endoscope. The scope ID and the model number information are information set by the manufacturer for each endoscope. The management name column displays a name added in order to make it easy to distinguish individual endoscopes in a medical facility. The scope ID, the model number information, and the management name are stored in the master information storage unit 62 in association with each other.

  With regard to the display contents of the status column, since many endoscopes are operating in the medical facility, the status information of ST1 to ST5 indicating the operating status is not displayed in the status column, but ST6 to ST8 indicating the non-operating status. Only the status information of is displayed in the status column. Therefore, the user recognizes that the endoscope is in operation by the blanking of the status column (status information non-display).

  The status column of the endoscope list shown in FIG. 3 is created only by the status information of each endoscope stored in the status storage unit 70. There may be an endoscope with a blank status column despite the presence. Therefore, in the embodiment, when the non-use period from the last cleaning date of the endoscope to the reference date exceeds the predetermined threshold value, a mechanism is proposed to infer that the endoscope is in the non-operating state. Hereinafter, it is assumed that the reference date is the display date of the list, that is, the current date (the current day).

  FIG. 4 shows an example of the cleaning information stored in the cleaning history storage unit 66. The cleaning history storage unit 66 stores cleaning information on cleaning of the endoscope. Here, “washing ID” is information for identifying washing, “washing start date” is the date when washing was started, and “washing end date” is the date when washing was completed, “washing” "Scope ID" is the scope ID of the cleaned endoscope. As described above, the registration unit 22 registers the cleaning information transmitted from the cleaning device 4 in the cleaning history storage unit 66. Although FIG. 4 shows cleaning information for three months from August 1, 2017 to October 31, 2017, the cleaning history storage unit 66 stores all cleaning performed by the current date and time. Information is stored. Hereinafter, it is assumed that the present date is November 15, 2017.

  The non-cleaning period extraction unit 30 refers to the cleaning information of the predetermined period stored in the cleaning history storage unit 66 to extract the non-cleaning period of the endoscope in the predetermined period. Here, the non-cleaning period is the number of days in which the cleaning is not performed continuously on the premise that the status information is in the operating state. Hereinafter, an example in which the non-washing period extraction unit 30 extracts the non-washing period of the endoscope with the management name “AA-1” for three months from August 1, 2017 to October 31, 2017 will be described. .

Here, the non-washing period extraction unit 30 refers to the washing history storage unit 66, and identifies the day when the record of washing the endoscope of “AA-1” does not exist as follows.
(1) August 4 to 7, 2017 (2) September 15, 2017 (3) October 2 to 3, 2017 (4) October 8 to 12, 2017 Note (1) On the day other than (4), there is an endoscope cleaning record.

Here, the non-washing period extraction unit 30 extracts the non-washing period, that is, the number of days in which the washing is not performed continuously. The non-washing periods extracted for (1) to (4) are as follows.
(1) 4 days (2) 1 day (3) 2 days (4) 5 days The non-washing period extraction unit 30 extracts the non-washing period in a predetermined period for all endoscopes.

  The threshold deriving unit 32 derives a determination threshold for determining the non-operating state of the endoscope based on the non-cleaning period extracted by the non-cleaning period extracting unit 30. Here, the threshold deriving unit 32 derives the determination threshold for each model number of the endoscope.

  Referring to FIG. 3, in the medical facility, three endoscopes of model number AA, four endoscopes of model number BB, and one endoscope of model number CC are registered. The endoscope list shown in FIG. 3 is assumed to be of November 15, 2017. At that time, the endoscope with model number BB of management name “BB-2” has been discarded.

The threshold deriving unit 32 calculates the average value of the non-operating period for each model number of the endoscope. Hereinafter, the non-cleaning period for three endoscopes of model number AA will be shown. In addition, the non-cleaning period of the endoscope of "AA-1" is 4 days, 1 day, 2 days, and 5 days as mentioned above.
Here, the non-washing period of “AA-2” is 2 days, 1 day, 1 day,
The non-washing period of “AA-3” is 3 days, 2 days, 2 days, 6 days and 2 days.
Therefore, the threshold deriving unit 32 calculates the average value of the non-operating period of the endoscope of model number AA as follows.
(4 + 1 + 2 + 5 + 2 + 1 + + 3 + 2 + 2 + 6 + 2) / 12 = 2.58

  The threshold deriving unit 32 derives a determination threshold for determining the non-operating state of the endoscope of model number AA based on the average value (2.58 days) of the non-operating period. For example, the average value itself may be derived as the determination threshold. The threshold derivation unit 32 stores the derived determination threshold in the determination threshold storage unit 72.

  The threshold deriving unit 32 derives a determination threshold for determining the non-operating state of the endoscope of the model number based on the average value of the non-operating period of the model number of the endoscope. The above is preparatory work for determining whether the endoscope is in the non-operating state. Since the frequency of use of endoscopes in medical facilities differs for each model number, it is possible to carry out the determination processing of the non-operating state based on the actual condition of the medical facility by deriving the determination threshold for each model number.

  The non-use period extraction unit 40 refers to the stored contents of the cleaning history storage unit 66 and extracts the non-use period from the last cleaning date of each endoscope to the reference date (current day). At this time, the endoscope which is a target for extracting the non-use period may be limited to the endoscope which is in the operating state, and the non-use period extracting unit 40 of the endoscope which is in the non-operating state. The non-use period may not be extracted. The reference date is assumed to be November 15, 2017.

Here the non-use period is
Calculated as (non-use period) = reference date-final cleaning date.
As a result, it is assumed that the non-use period of the endoscope of the three endoscopes of model number AA is calculated as follows.
AA-1: Non-use period 2 days AA-2: Non-use period 1 day AA-3: Non-use period 3 days

  The determination unit 42 compares the extracted non-use period with the determination threshold, and determines that the endoscope is in the non-operating state on the reference date when the non-use period is longer. In the determination threshold storage unit 72, the determination threshold of the endoscope of model number AA is stored as 2.58 days, so the determination unit 42 determines that the non-use period of the endoscope of “AA-3” is greater than the determination threshold Also, it is determined that the “AA-3” endoscope is in a non-operating state.

The display processing unit 44 has a function of displaying the state of the endoscope on the display screen of the endoscope list.
FIG. 5 shows an example of the display screen of the endoscope list held by the medical facility. The display processing unit 44 receives the determination result by the determination unit 42, and displays "not in operation" in the state column of the endoscope of "AA-3". That is, the display processing unit 44 displays the non-operating state as the state of the “AA-3” endoscope determined to be the non-operating state. Compared with the endoscope list shown in FIG. 3, the display processing unit 44 takes into consideration the determination result by the determination unit 42, not using only the status information of each endoscope stored in the status storage unit 70. By determining the display content of the status column, it is possible to notify the user of the presence of the endoscope which is likely to have the status of ST6 to ST8.

  It should be noted that “non-operation” displayed for “AA-3” is determined to be non-operation only because it has been determined to be non-operation because the non-use period is longer than the determination threshold. It is not something that Therefore, when the user confirms the status display of "inactive" in the endoscope list, the user checks the actual status of the endoscope and corrects the status display of the endoscope list correctly.

  FIG. 6 shows a candidate window for status display. When the user places the mouse pointer on the "inactive" display and clicks the right button, a candidate window 80 including candidate statuses for changing the "inactive" display is displayed. The user can change the "inactive" display to the appropriate status by selecting the correct endoscope status.

  The present invention has been described above based on a plurality of embodiments. It is understood by those skilled in the art that these embodiments are exemplifications, and that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. is there.

  In the embodiment, the threshold deriving unit 32 derives the determination threshold for each model number based on the average value of the non-working period for each model number, but the average value of the non-working period for each endoscope, that is, for each individual Based on the decision threshold for each individual may be derived. In this case, the determination unit 42 may compare the nonuse period and the determination threshold for each individual to determine whether the individual is in a non-operating state.

  In addition, although the threshold value deriving unit 32 derives the average value itself of the non-operating period as the determination threshold value, it may derive a value larger than the average value as the determination threshold value. For example, the threshold derivation unit 32 may derive the determination threshold by adding a predetermined value α (> 0) to the average value. Further, the threshold derivation unit 32 may derive the determination threshold by multiplying the average value by the predetermined value β (> 1). In any case, when the threshold deriving unit 32 sets a value larger than the average value as the determination threshold, it is possible to reduce the frequency at which the endoscope is determined to be in the “non-operating” state.

  In the embodiment, the non-washing period extraction unit 30 extracts the non-washing period in the past three months, but this period may be arbitrarily changed. In addition, in the non-washing period, a period exceeding a predetermined long number of days (for example, 15 days) may be treated as an abnormal number of days and may not be extracted because the influence on the average value is too large.

  If the determination unit 42 determines that the endoscope is not in operation, the determination result may be notified to the status management unit 24, and the status management unit 24 may change the status of the endoscope. At this time, the status management unit 24 may set the “non-operation” status and store it in the status storage unit 70.
