In the server device 200, the communication unit 202 receives the worker ID, the endoscope ID, and the cleaning device ID, and stores them in the storage unit 210 as cleaning information. In the first embodiment, the state determination unit 110 determines the arrangement state of the endoscope and the state of various components based on image data of the imaging of the cleaning tank 11 by the imaging unit 14. Information about the determination result is transmitted to the server device 200 and stored in the storage unit 210 as a part of the cleaning information.

(4) The opening / closing detection unit 22 detects opening / closing of the lid 13. The opening / closing detection unit 22 has a contact switch that outputs an ON signal when the lid 13 is closed and outputs an OFF signal when the lid 13 is open, and detects opening and closing of the lid 13 based on the output of the contact switch. May be. When the opening / closing detection unit 22 detects the opening operation of the lid 13, the communication unit 12 transmits information indicating that the lid 13 has been opened (lid opening information) to the mobile terminal device 100. In the mobile terminal device 100, the communication unit 102 receives the lid opening information and supplies the information to the notification control unit 120.

The storage unit 130 stores guide information regarding preparation for cleaning the endoscope. The guide information indicates a procedure and a precaution for the operator to correctly set the endoscope in the cleaning tank 11, and the storage unit 130 stores the guide information for each endoscope model. I have. When the notification control unit 120 acquires the endoscope ID and the lid opening information, the notification control unit 120 reads the guide information associated with the type of the endoscope ID from the storage unit 130 and outputs the guide information to the notification unit 122. Here, the notification unit 122 is a display provided in the mobile terminal device 100, and the notification control unit 120 supplies guide information to the display, and notifies the display of the guide information. The notification unit 122 may be a speaker, and the notification control unit 120 may output audio information from the speaker as guide information for correctly setting the endoscope in the cleaning tank 11.

3 to 6 show examples of guide information notified from the notification unit 122. FIG.
FIG. 3 shows an example of notification of a check item related to the mesh filter of the cleaning tank 11. The notification control unit 120 causes the notification unit 122 to display confirmation items related to the mesh filter.
FIG. 4 shows a notification example regarding waterproofing of the connector of the endoscope. The notification control unit 120 causes the notification unit 122 to display a work instruction for connecting the waterproof cap to the connector.
FIG. 5 shows an example of notification of confirmation items related to the washing tube. The notification control unit 120 causes the notification unit 122 to display confirmation items regarding the cleaning tube.
FIG. 6 shows a notification example of a procedure for disposing an endoscope in the cleaning tank 11. The notification control unit 120 causes the notification unit 122 to display a procedure for arranging the endoscope. The endoscope is wound and arranged in the cleaning tank 11 a plurality of times.

The procedure for arranging the endoscope shown in FIG. 6 is as follows.
(1) Wrap the insertion section inward in the clockwise direction from the outside of the holding net (the first lap of the insertion section is outside the marking, and the second lap is inside the marking)
(2) Wind the universal cord counterclockwise inside the insertion section. At this time, the universal cord is housed inside the hook, and the RFID tag of the endoscope is moved toward the scope connector. If the band is twisted, correct it.
The cleaning operator arranges the endoscope in the cleaning tank 11 according to this procedure.

The notification control unit 120 may display the notification screens shown in FIGS. 3 to 6 on the notification unit 122 for a predetermined period of time (for example, 15 seconds), or may switch the display according to an instruction such as a voice of a cleaning worker. The notifying unit 122 displays, on the notifying screen, a diagram of a corresponding portion in the cleaning tank to be worked, together with text data indicating confirmation items and procedures on the notifying screen, so that the cleaning operator can intuitively understand the contents to be noted. it can. The cleaning operator looks at the screen displayed on the notification unit 122, sets various components in the cleaning tank 11 in an appropriate state, and confirms a procedure for appropriately arranging the endoscope in the cleaning tank 11.

The cleaning operator sets various components in the cleaning tank 11, places the endoscope in the cleaning tank 11, and closes the lid 13. When the open / close detection unit 22 detects the closing operation of the lid 13, the imaging control unit 20 supplies an imaging instruction to the imaging unit 14. Upon receiving the photographing instruction, the photographing control unit 20 photographs the cleaning tank 11 in which the endoscope is arranged. Note that the imaging control unit 20 may supply an imaging instruction to the imaging unit 14 upon an event other than the closing operation of the lid 13 as a trigger.

For example, the imaging control unit 20 supplies an imaging instruction to the imaging unit 14 according to an instruction from the cleaning operator. When the cleaning device 10 has a voice recognition function (not shown), a radiographing instruction may be received from the cleaning operator and the photographing instruction may be supplied to the imaging unit 14. When the cleaning device 10 has a line-of-sight detection function (not shown), the cleaning operator directs the line of sight in a predetermined direction for turning on the release switch of the imaging unit 14, and the imaging control unit 20 issues a shooting instruction. It may be supplied to the imaging unit 14. When the cleaning device 10 has a gesture detection function (not shown), the cleaning operator takes a predetermined gesture to turn on the release switch of the imaging unit 14, and the imaging control unit 20 issues an imaging instruction to the imaging unit. 14 may be provided. The gaze detection and the gesture detection of the cleaning worker may be executed by analyzing an image captured by the imaging unit 18. When a function of turning on a release switch of the imaging unit 14 is associated with a stepping operation of a foot pedal (not shown), the photographing control unit 20 issues a photographing instruction when the cleaning operator steps on the foot pedal. May be supplied to the imaging unit 14. Further, when the cleaning operator presses the cleaning start button of the cleaning device 10, the imaging control unit 20 may supply an imaging instruction to the imaging unit 14.

(4) When the imaging control unit 20 supplies an imaging instruction to the imaging unit 14, the imaging unit 14 images the cleaning tank 11 in which the endoscope is arranged. The communication unit 12 transmits the captured image data to the portable terminal device 100, and the communication unit 102 receives the image data and supplies the image data to the state determination unit 110 and the notification control unit 120. In the first embodiment, the imaging unit 14 acquires still image data, but may acquire moving image data.

In the portable terminal device 100, the storage unit 130 stores reference data representing a state in which the endoscope is appropriately arranged in the cleaning tank 11 in association with the endoscope type and the cleaning device type. Further, the storage unit 130 stores reference data representing a state in which various components are appropriately arranged in the cleaning tank 11 in association with a cleaning device model. When the image data is supplied to the state determination unit 110, the analysis unit 112 reads the reference data regarding the arrangement of the endoscope and the reference data regarding the components of the cleaning device from the storage unit 130, and includes the reference data included in the captured image data. It analyzes whether the arrangement state of the endoscope and the state of various components are appropriate. The reference data may be configured as image data in order to compare the captured image data and the reference data by image analysis.

FIG. 7 is a view for explaining an algorithm for determining the arrangement state of the endoscope arranged in the cleaning tank 11. The analysis unit 112 determines whether the arrangement state of the endoscope or the state of various components in the cleaning tank 11 is appropriate based on image data obtained by photographing the cleaning tank 11.

FIG. 7A shows a state in which an endoscopic image is extracted from a captured image. The analysis unit 112 has an object detection function of detecting an endoscope from a captured image by performing image analysis, and specifies an endoscope image 150 included in the captured image.

FIG. 7B shows an example of the reference image. This reference image represents a storage area 152 in which the endoscope should be stored when the endoscope is placed in the cleaning tank 11. As shown in FIG. 6, since the endoscope is wound and arranged in the cleaning tank 11 a plurality of times, the accommodation area 152 in which the endoscope is to be accommodated is a substantially donut-shaped area. In this example, the accommodation area 152 is shown as an image for easy understanding, but the accommodation area 152 may be expressed as coordinate data that specifies a range in which the endoscope image 150 should be included in the captured image. Good.

The analysis unit 112 superimposes the storage area 152 in the reference image and the endoscope image 150 in the captured image, and if the endoscope image 150 is within the storage area 152, the endoscope is placed in the cleaning tank 11. It is determined that it is in an appropriate arrangement state.

FIG. 7 (c) shows a state in which the accommodation area 152 in the reference image and the endoscope image 150 in the captured image are superimposed. In this example, the endoscope image 150 includes a portion protruding from the accommodation area 152. When the endoscope image 150 included in the captured image protrudes from the accommodation region 152 of the reference image, the analysis unit 112 determines that the endoscope is not in an appropriate arrangement state.

FIG. 7D shows an area where the endoscope image 150 protrudes from the accommodation area 152. When the analyzing unit 112 determines that the endoscope is in an inappropriately arranged state, the inappropriate region identifying unit 114 identifies a photographing region in the photographed image data in which it is determined that the endoscope is in an inappropriately arranged state. In FIG. 7D, the protruding regions 156a to 156d (hereinafter, referred to as “protruding region 156” unless otherwise specified) are determined by the analysis unit 112 to be in an inappropriately arranged endoscope state. The improper area specifying unit 114, which is a photographing area, receives the image analysis result from the analyzing unit 112 and specifies the protruding area 156 which is an improper part in the photographed image.

The state determination unit 110 notifies the notification control unit 120 of the determination result and information on the protruding area 156. The state determination unit 110 may notify the notification control unit 120 of the determination result and information on the protruding region 156 only when determining that the arrangement state of the endoscope is not appropriate. The notification control unit 120 generates notification data regarding the notified determination result, and outputs the notification data to the notification unit 122.

FIG. 8 shows an example of a warning about a placement of an endoscope. The notification control unit 120 generates text notification data and outputs it to the notification unit 122, and the notification unit 122 displays a text warning on a display. Note that the notification unit 122 may output text data by voice. Thus, the cleaning operator recognizes that the endoscope has not been properly arranged, opens the lid 13, and correctly rearranges the endoscope in the cleaning tank 11.

FIG. 9 shows another example of a warning about the arrangement of the endoscope. The notification control unit 120 generates, as notification data, image data in which the imaging region specified as the protruding region 156 is marked, together with the text data, and outputs the image data to the notification unit 122. The marking image 160 shown in FIG. 9 is an image in which the protruding area 156 in FIG.

マーキング The marking in the protruding area 156 may be any marking that allows the cleaning operator to understand at a glance the inappropriate portion. Therefore, the notification control unit 120 may reconstruct the captured image data by giving a predetermined color to the protruding area 156 or highlighting it, such as shading, in addition to enclosing it with a broken line. By highlighting the inappropriate portion by marking the protruding area 156, the cleaning operator can understand at a glance the points to be corrected.

FIG. 10 shows still another example of a warning about the placement of the endoscope. The notification control unit 120 generates, as notification data, image data indicating an appropriate arrangement state of the endoscope in the imaging region specified as the protruding region 156, together with the text data, and outputs the image data to the notification unit 122. The correct image 162 shown in FIG. 10 is an image showing the position where the endoscope should be originally placed in the protruding area 156 shown in FIG.

The cleaning operator can confirm the position of the endoscope to be originally disposed by looking at the correct answer image 162. The correct answer image 162 expresses a difference between the endoscope in an inappropriately arranged state and the endoscope in an originally arranged state, but the notification control unit 120 displays the image of the difference. May be generated as image data superimposed on the captured image.

FIG. 11 shows still another example of a warning about the placement of the endoscope. When the analysis unit 112 determines that the endoscope is in an inappropriately arranged state, the procedure identifying unit 116 identifies a procedure for setting the endoscope in an appropriate arrangement state. The analysis unit 112 determines from the image analysis result which stage of the prescribed procedure has been achieved and which stage has not been achieved.

As described above, the procedure for arranging the endoscope is as follows.
(1) Wrap the insertion section inward in the clockwise direction from the outside of the holding net (the first lap of the insertion section is outside the marking, and the second lap is inside the marking)
(2) Wind the universal cord counterclockwise inside the insertion section. At this time, the universal cord is housed inside the hook, and the RFID tag of the endoscope is moved toward the scope connector. If the band is twisted, correct it.
This procedure is stored in the storage unit 130.

For example, the analyzing unit 112 analyzes the photographed image and confirms that the insertion portion is sequentially wound in a clockwise direction from the outside of the holding net, while the universal cord is turned counterclockwise inside the insertion portion. Make sure it is not wound. At this time, the analysis unit 112 determines that the procedure (1) has been performed but the procedure (2) has not been performed.

(4) The procedure specifying unit 116 receives the determination result of the analysis unit 112 and specifies a procedure for setting the endoscope in an appropriate arrangement state. Specifically, the procedure specifying unit 116 specifies a procedure (2) for setting the endoscope in an appropriate arrangement state in the arrangement procedure of the endoscope stored in the storage unit 130, and notifies the notification control unit 120. I do. The notification control unit 120 generates, as the notification data, data indicating a procedure for setting the endoscope determined to be in an inappropriate arrangement state to an appropriate arrangement state. The notification control unit 120 outputs the notification data to the notification unit 122 for display. The cleaning operator can efficiently rearrange the endoscope by checking the procedure (2) relating to the arrangement of the endoscope.

When the analysis unit 112 determines that the endoscope is in an inappropriately arranged state, the notification control unit 120 determines whether the cleaning device 10 has cleaned the endoscope while the endoscope is in an inappropriately arranged state. May be generated as notification data and output to the notification unit 122. The notification control unit 120 may generate, as the notification data indicating the risk, text data indicating that “the cleaning may be insufficient because the endoscopes are arranged overlappingly”.

As described above, when the analysis unit 112 determines that the endoscope is in an inappropriately arranged state, the notification control unit 120 transmits notification data indicating that the endoscope is in an inappropriately arranged state. Generate. The notification data is notified from the notification unit 122, and the cleaning operator is given an opportunity to immediately rearrange the endoscope appropriately.

The analysis unit 112 may determine whether the arrangement state of the endoscope is appropriate using another state determination algorithm. For example, when the specific portion (the distal end of the insertion section or the operation section) or the index (the scale of the insertion section or the like) of the endoscope is within a predetermined range in the captured image, the analysis section 112 appropriately controls the endoscope. It may be determined that they are arranged. In addition, the analysis unit 112 compares the image of the endoscope in a normally arranged state with the image of the endoscope included in the captured image, and determines that the degree of coincidence between the two images exceeds the threshold. Alternatively, it may be determined that the endoscope is appropriately arranged. In addition, the analysis unit 112 may determine whether the arrangement of the endoscope is appropriate using a model that has undergone machine learning. In any case, the analysis unit 112 determines the quality of the arrangement state of the endoscope using photographed image data of the cleaning tank 11 in which the endoscope is arranged.

The processing for determining the arrangement state of the endoscope has been described above. However, the analysis unit 112 determines not only the arrangement state of the endoscope but also various components in the cleaning tank 11 based on image data obtained by photographing the cleaning tank 11. It may also be determined whether the state is appropriate.
<Installation of mesh filter>
The analysis unit 112 compares the region of the mesh filter included in the reference image with the region of the captured image where the mesh filter is to be captured, and determines whether the mesh filter is appropriately arranged.
<Connection of waterproof cap>
The analysis unit 112 compares the area of the waterproof cap included in the reference image with the area of the captured image where the waterproof cap is to be photographed, and determines whether the waterproof cap is properly connected to the connector.
<Installation of washing tube>
The analysis unit 112 compares the region of the cleaning tube included in the reference image with the region of the captured image where the cleaning tube is to be photographed, and determines whether the cleaning tube is appropriately arranged.

When the analysis unit 112 determines that the state of the component in the cleaning tank 11 is not appropriate, the notification control unit 120 generates notification data on the determination result and outputs the notification data to the notification unit 122. The notification control unit 120 generates notification data customized according to the component. The notification unit 122 may display a notification screen similar to that shown in FIGS.

In the first embodiment, the notification control unit 120 outputs notification data to the notification unit 122 which is a display of the mobile terminal device 100. The notification unit 122 is not limited to the display of the mobile terminal device 100, and may be, for example, a display installed near the cleaning device 10. The notification unit 122 may be a projector that projects an image or a virtual image display. When the notification screen is displayed on the notification unit 122, the notification control unit 120 generates at least one of voice, light, and vibration from the notification unit 122, and provides the cleaning operator with the arrangement state of the endoscope or the state of the component. You may notice that is inappropriate.

洗浄 In the cleaning device 10, the cleaning management unit 24 controls the cleaning process of the cleaning device 10. Information about the determination result by the analysis unit 112 is transmitted from the communication unit 102 to the cleaning device 10 and supplied to the cleaning management unit 24. When the analysis unit 112 determines that the arrangement state of the endoscope or the state of the component is inappropriate, the cleaning management unit 24 restricts the start of the cleaning process when acquiring the information on the determination result. That is, even if the cleaning start button of the cleaning device 10 is operated by the cleaning operator, the cleaning management unit 24 treats the operation as an invalid operation. When the cleaning management unit 24 restricts the start of cleaning, the communication unit 12 transmits information indicating that the start of cleaning is restricted to the portable terminal device 100. When the communication unit 102 receives the information, the notification control unit 120 may notify the notification unit 122 that the cleaning process cannot be started because the arrangement state of the endoscope or the state of the component is inappropriate.

When the result of the determination indicates that the arrangement state of the endoscope and the state of the components are appropriate, the cleaning management unit 24 operates the cleaning start button by operating the cleaning start button without limiting the start of the cleaning step. To start.

FIG. 12 is a flowchart showing the management processing of endoscope cleaning. With the lid 13 of the cleaning device 10 opened (N in S10), the cleaning operator sets various components in the cleaning tank 11 and places the endoscope in the cleaning tank 11. When the cleaning operator finishes the operation of arranging the endoscope and closes the lid 13, the opening / closing detection unit 22 detects the closing operation of the lid 13 (Y in S <b> 10). Supply a shooting instruction. Upon receiving the photographing instruction, the imaging unit 14 photographs the cleaning tank 11 in which the endoscope is arranged (S12).

The state determination unit 110 analyzes the captured image (S14) and determines whether the arrangement state of the endoscope or the state of the components in the cleaning tank 11 is appropriate (S16). Here, if both the arrangement state of the endoscope and the state of the components are appropriate (Y in S16), the cleaning management unit 24 starts the cleaning process by operating the subsequent cleaning start button. On the other hand, if the arrangement state of the endoscope or the state of the components is not appropriate (N in S16), the notification control unit 120 generates a warning message indicating that the state is inappropriate, and the notification unit 122 displays the warning message. Is notified (S18). At this time, the cleaning management unit 24 limits the start of the cleaning process, and treats the operation of the cleaning start button as an invalid operation (S20).

The server device 200 collects information on cleaning from the cleaning device 10 and the portable terminal device 100, and performs statistical processing.
The communication unit 202 receives a combination of the endoscope ID, the cleaning device ID, and the worker ID from the communication unit 12 of the cleaning device 10. The communication unit 202 receives, from the communication unit 102 of the mobile terminal device 100, information on the determination result in the state determination unit 110. The storage unit 210 stores, as cleaning information, at least one of the endoscope ID, the cleaning device ID, and the worker ID in association with the information on the determination result for each cleaning process of the endoscope. The storage unit 210 may store, in addition to these pieces of information, the time required for the cleaning operator to arrange the endoscope, and the like as cleaning information. Therefore, the storage unit 210 accumulates information on the cleaning process performed in the medical facility.

The statistical processing unit 204 generates a statistical value related to the frequency at which it is determined that the arrangement state of the endoscope or the state of the component is inappropriate based on the cleaning information stored in the storage unit 210. For example, the statistical processing unit 204 may generate, for each worker ID, a statistical value related to the frequency at which the arrangement state of the endoscope or the state of the component is determined to be inappropriate. This statistical value is an index indicating whether the operator can accurately perform the operation of arranging the endoscope. In this example, the statistic is the failure rate when the endoscope is placed in the cleaning tank 11, and a high statistic indicates that the operator cannot perform the endoscope placement work properly, and a low statistic. Indicates that the operator can appropriately perform the operation of arranging the endoscope. By generating such statistics, it is possible to objectively evaluate the endoscope placement skills of the worker.

The worker identifying unit 206 acquires the statistical value of each worker generated by the statistical processing unit 204 and identifies a worker having a low endoscope placement skill and a worker having a high endoscope placement skill. . The worker identification unit 206 is a worker ID of a cleaning worker whose statistic larger than the first threshold is calculated, and / or a worker of a cleaning worker whose statistic smaller than the second threshold is calculated. The ID may be specified. The cleaning worker whose statistic larger than the first threshold is calculated is a worker having a low endoscope placement skill, and the cleaning worker whose statistic smaller than the second threshold is calculated is an endoscope. Worker with high mirror placement skills. Here, the second threshold is smaller than the first threshold. The communication unit 202 transmits the worker ID specified by the worker specifying unit 206 to the cleaning device 10.

In the cleaning device 10, when the communication unit 12 receives the worker ID of a worker with a high endoscope placement skill and / or a worker with a low endoscope placement skill, the communication unit 12 supplies the worker ID to the imaging control unit 20. The photographing control unit 20 uses the supplied worker ID as a start condition of moving image photographing by the image capturing unit 18.

When the ID acquisition unit 16 acquires the worker ID of the cleaning worker before the start of cleaning the endoscope, the imaging control unit 20 determines that the acquired worker ID matches the worker ID supplied from the server device 200. It is determined whether to do. When the acquired worker ID matches the worker ID supplied from the server device 200, the worker is a worker having a high endoscope placement skill or a worker having a low endoscope placement skill. It is. At this time, the imaging control unit 20 causes the imaging unit 18 to start moving image imaging. The imaging control unit 20 may continue the moving image imaging by the imaging unit 18 until the opening / closing detection unit 22 detects the lid closing operation.

動画 Movies that capture the placement work of workers with high endoscope placement skills are learning materials for beginners in cleaning work and workers with low endoscope placement skills. In addition, a moving image of a worker who has a low endoscope placement skill is used as a material for educating the worker. In this way, the imaging control unit 20 may cause the imaging unit 18 to image the state of the endoscope placement operation of the worker for the purpose of education.

The storage unit 210 may store information on the inappropriate area specified by the inappropriate area specifying unit 114. When the analyzing unit 112 determines that the arrangement state of the endoscope or the state of the component is inappropriate, information indicating the position (part) or component of the endoscope determined to be inappropriate is transmitted to the communication unit. It may be transmitted from 102 to the server device 200 and stored in the storage unit 210. The statistical processing unit 204 may generate a statistical value related to the frequency at which the arrangement state of the endoscope or the state of the component is determined to be inappropriate based on the information stored in the storage unit 210.

When the statistical processing unit 204 generates a statistic based on an endoscope or a component, the statistic may be used to specify, for example, an endoscope or a component that is likely to be misplaced. In addition, in an endoscope in which misplacement is likely to occur, it may be used to specify at which position (place) the misplacement occurs. When the statistical processing unit 204 generates the statistic based on the cleaning device, the statistic may be used, for example, to specify a cleaning device in which misplacement is likely to occur.
