Can be associated with an image.

  The date and time attached to the image taken by the clock function of the surveillance camera can be used as the shooting date and time.

  Next, the operation of the medical device management system according to the present invention will be described.

  Note that it is desirable to install the monitor devices 40 at a plurality of locations (each work location).

<First Embodiment>
When an operator handles an endoscope as a work target, the operator confirms the work history of the endoscope with an image.

  In this case, the operator inputs the device ID of the RFID tag attached to the endoscope to the management server 30. The device ID may be input by the operator operating the keyboard 41, or an RFID tag attached to the endoscope by an RFID tag reader (not shown) attached to the management server 30. May be read.

  Here, it is desirable to install a keyboard and a display monitor or an RFID tag reader for each work place. Alternatively, an RFID tag reader may be installed in each operation target device (endoscopic processor, washing machine, storage, etc.), and the read device ID may be transmitted to the management server 30 via the LAN.

  Further, the endoscope is transported along the flow of a storage room (endoscope storage) → inspection room (endoscope processor) → cleaning room (cleaning apparatus) → storage room. The operator appropriately selects, using the keyboard 41 or the like of the management server 30, whether to trace the entire movement history and work history of the endoscope or to trace a specific position (or a specific work step). When tracing a specific work step, the position information of the work step or the work information to be confirmed is input.

  For example, when “001” is input as the device ID and the entire trace is selected, the CPU 31 manages all images managed by the device ID “001” from the database shown in FIG. In this form, a moving image) is extracted, and the extracted images are arranged in the order of shooting time to form a series of moving images. Subsequently, a plurality of still images for confirming the entire moving image is extracted from a series of moving images, and an index image (still image index image) for displaying a list by reducing these still images is generated.

  In addition, as a method of extracting a plurality of still images from a moving image, a method of analyzing a shooting scene and extracting a frame image when the shooting scene changes, dividing a moving image at a predetermined time interval, and dividing each moving image A method for extracting a representative image (for example, the top frame image) from each of them, and other known methods can be used.

  The still image index image edited as described above is displayed on the monitor device 40. The operator can intuitively confirm the work history and the movement history of the work target endoscope by visually recognizing the still image index image displayed on the monitor device 40.

  In the still image index image shown in FIG. 4, the operator carries the endoscope into the cleaning device (still images (1) to (2)), and then sets the endoscope in the cleaning device (still image (3 ) To (5)), the endoscope is taken out from the cleaning device after the cleaning is finished (still image (6)), and the endoscope after the cleaning is carried into the endoscope storage (still image (7)). A state (still images (8) and (9)) of leaving after the endoscope is stored in the endoscope storage is shown.

  The operator must confirm that the endoscope was properly cleaned and stored (the safety of the endoscope) when the endoscope stored in the endoscope storage is brought into the examination room. However, it can be intuitively confirmed from the above-mentioned still image index image, thereby preventing an operation error.

The example shown in FIG. 4 shows a case where a specific work step is traced (the operation from cleaning to storage during the operation of carrying the endoscope into the examination room) is traced. As an example for tracing:
・ When carrying the endoscope into the storage room:
Check that the work from the start to the end of cleaning is normal ・ When setting the endoscope to the cleaning device:
For example, check whether the work from the start of inspection to unloading is normal.

  When tracing a specific work step, the operator inputs information (photographing location, work content) indicating the work step with the keyboard 41 or selects it with the mouse 42 from a menu prepared in advance.

  When information indicating a specific work step is input together with the device ID, the CPU 31 searches only the necessary images based on the information, generates the above-described still image index image from the searched images, and monitors the monitor device. 40.

  The operator can trace the history of the endoscope at a desired work step by visually recognizing the still image index image displayed on the monitor device 40. ), Whether the endoscope is not hung or whether the endoscope is touching somewhere.

  In some cases, a plurality of operators share the work of the endoscope and take over the work. In this case, the work contents of other operators can be intuitively confirmed by the still image index image.
