As a result, when AC power is being supplied to the power input unit 61, the power input unit 61 is in a state where the backup power supply unit 63 can always be charged. The power supply connection detection unit 64 detects whether AC power is being supplied to the power supply input unit 61 and outputs the detection result to the power supply switching unit 62. When a state in which AC power is being supplied to the power input unit 61 (hereinafter referred to as a power-on state) is indicated, the power supply switching unit 62 uses the power supply voltage from the power input unit 61 as an internal power supply to provide medical images. When a state in which AC power is not supplied to the power input unit 61 (hereinafter referred to as a power cutoff state) is supplied to each unit of the recording device 50, the backup power supply from the backup power supply unit 63 is supplied internally. Is supplied to each part of the medical image recording device 50.

In the present embodiment, the detection result of the power supply connection detection unit 64 is also supplied to the storage unit 57, the operation determination unit 58, and the control unit 59. When the detection result indicates that the power-off state is switched to the power-on state, the storage unit 57 outputs the inspection information stored immediately before the power-off state to the operation determination unit 58. When it is detected that the power has been switched from the power-off state to the power-on state, the operation determination unit 58 receives, for example, the information stored in the storage unit 57 before the power-off and the power input via the communication unit 56. The operation determination for determining the recording control method is performed based on the inspection information after the loading state.

In the present embodiment, the control unit 59 can perform a saving process for surely storing in the storage unit 57 the information necessary for the recording control after the power is turned on during the operation by the backup power supply. ing. That is, the control unit 59 causes the storage unit 57 to save the self-device information and the inspection information during the operation by the backup power supply. The control unit 59 may cause the communication unit 56 to receive the inspection information and store the received inspection information in the storage unit 57 during the operation by the backup power supply.

Further, when the detection result indicates that the power-on state has been switched to the power-off state, the control unit 59 can determine whether or not a predetermined termination process in the medical image recording device 50 is completed. It has become. For example, the control unit 59 can determine whether or not the own unit information regarding the state of the own unit has been saved in the storage unit 57 immediately after the transition from the power-on state to the power-off state. The results of these determinations made by the control unit 59 are supplied to the operation determination unit 58.

When the control unit 59 changes from the power-on state to the power-off state and determines that the termination process has been completed, the control unit 59 controls the shutdown of the medical image recording apparatus 50. Further, when the control unit 59 is provided with a detection result indicating that the power is turned off and then turned on, the control unit 59 instructs the communication unit 56 to receive the inspection information.

The start and end of the recording of the medical image can be instructed not only by the operation of the operation/display unit 60 but also by the operation of the endoscopes 31, 32 and the processors 15, 23.

FIG. 3 is a chart showing the contents of the setting information stored in the storage unit 57.

In the present embodiment, the storage unit 57 stores setting information for recording control after power-on as shown in FIG. After the power is turned on, the operation determination unit 58 controls at least one of the self-machine information and the inspection information stored in the storage unit and the inspection information newly acquired by the communication unit, by comparing the recording information with the setting information. Decide how. The control unit 59 executes the recording control according to the recording control method determined by the operation determination unit 58. The setting information in the storage unit 57 may be able to be appropriately updated based on a user operation.

In the example of FIG. 3, an example of controlling the recording after the power is turned on based on the patient ID, the examination ID, the date and time information, and the information on the self-device at the time of power-off is shown, but control using other examination information is performed. You may go and control contents are not limited to this.

FIG. 3 shows an example in which the operation determination unit 58 determines whether to continue recording or to wait for recording when the power is turned on, depending on whether the state of the device at power-off is recording or not recording. Shows. Further, the operation determination unit 58 determines whether to continue recording or waits by comparing the inspection information stored before power-off with the inspection information received after power-on, and creates a new folder. An example of deciding whether or not to record is shown.

That is, the operation determination unit 58 obtains the comparison result of the inspection information when the power is cut off and when the power is turned on. When the comparison of the examination information indicates that the examination is performed on a different patient depending on the patient ID, the operation determination unit 58 causes the control unit 59 to perform the operation as shown in “New recording operation” in FIG. Create a new folder and instruct to store medical images in the created folder. If the comparison result shows that the same patient has different tests depending on the test ID, the motion determination unit 58 causes the control unit 59 to create a new folder, and Instruct to store medical images. Furthermore, when the date and time information indicates that the dates (time stamps) do not match, the operation determination unit 58 causes the control unit 59 to create a new folder and stores the medical image in the created folder. To instruct.

Note that, in FIG. 3, when it is shown that the dates are different depending on the time stamps, an example in which the recorded data of the medical image is recorded in different folders for each date is shown. The folder in which the record data is recorded may be determined only by the patient ID and the examination ID. For example, when the patient ID and the examination ID at the time of power-off and at the time of power-on are the same, the control unit 59 follows the instruction of the operation determination unit 58, and even if the dates do not match, the control unit 59 stores the medical information in the existing folder. You may control so that an image may be stored.

Further, when the communication unit 56 is unable to acquire the inspection information when the power is turned on, the operation determination unit 58 determines that it is impossible to determine whether the inspection information matches or fails, and the operation determination unit 58 adds a new information to the control unit 59. A folder may be created and an instruction may be given to store the medical image in the created folder.

Although not shown in FIG. 3, the motion determination unit 58 may instruct different recording controls for a moving image and a still image in the medical image. For example, it is also possible to change the folder for recording a still image according to FIG. 3 and not change the folder for a moving image.

4A and 4B are explanatory diagrams for explaining an example in which different recording control is performed for a moving image and a still image. 4A and 4B show a folder structure in the recording area 53a of the recording unit 53. Both FIG. 4A and FIG. 4B show that the inspection with the changed inspection ID was performed three times in one day. In the example of FIG. 4A, the recording data of the moving image in the medical image is sequentially recorded in different folders Fm1, Fm2, and Fm3 each time the examination ID is switched. Further, in the example of FIG. 4A, the record data of the still image in the medical image is sequentially recorded in different folders Fp1, Fp2, Fp3 each time the examination ID is switched. In general, moving image recording data and still image recording data are often stored in a common folder. In this case, Fm1=Fp1, Fm2=Fp2, Fm3=Fp3. As shown in FIG. 4A, folders for moving images and still images may be provided separately.

On the other hand, in FIG. 4B, the record data of the still image in the medical image is sequentially recorded in different folders Fp1, Fp2, and Fp3 each time the examination ID is switched, whereas the moving image of the medical image is recorded. Regarding the recording data, it indicates that the moving image file is recorded in the common folder Fm11 without switching the folders.

As described above, the operation determination unit 58 refers to the setting information in FIG. 3 based on the operation determination result to determine the folder to be recorded and the permission/inhibition of recording. The recording control desired by the user can be performed by appropriately changing the setting information shown in FIG. 3 based on the user operation.

Next, the operation of the embodiment thus configured will be described with reference to FIG. FIG. 5 is a flowchart for explaining the recording control when the power is turned off and when the power is turned on.

Now, an endoscopic examination is performed. Prior to the endoscopic examination, the user sets the patient ID, the examination ID, and the date and time by the processors 15, 23 and the like. The processors 15 and 23 output the patient ID, the examination ID, and the date and time information to the medical image recording apparatus 50. In the present embodiment, the medical image recording apparatus 50 uses not only the patient ID but also the examination ID and date/time information for recording control.

When the AC power is turned on in step S1, the medical image recording apparatus 50 newly obtains examination information in step S2, obtains the examination information stored in step S3, and then, in step S4, determines whether the power is cut off. Get own device information. The control unit 59 may initialize the storage unit 57 in the course of the shutdown process when the power is shut off at the timing when no medical image is recorded and the normal shutdown process is performed due to the power shutdown. ..

Now, as a result of such a normal shutdown process, it is assumed that the storage unit 57 does not hold the inspection information and the own-machine information when the power is turned on. In this case, the recording control is performed only by the inspection information received in step S2. For example, the communication unit 56 receives the patient ID, the examination ID, the date and time information, and the like as the examination information. The medical image recording device 50 may also receive the connected device information as the inspection information. The examination information such as the patient ID, the examination ID, and the date and time information received by the communication unit 56 is given to the storage unit 57 and stored therein.

Although not shown in FIG. 5, the control unit 59 controls the communication unit 56 so as to receive the inspection information at an appropriate timing. Further, the control unit 59 is also configured to store the own device information indicating whether or not a medical image is being recorded in the storage unit 57. The processors 15 and 23 output the examination ID corresponding to the examination content set by the user each time the examination is switched, and the patient ID corresponding to the patient set by the user every time the examination target patient is switched. Is output. Upon receiving the inspection information from the processors 15 and 23, the communication unit 56 stores the received inspection information in the storage unit 57. Thus, the latest inspection information is stored in the storage unit 57.

The operation determination unit 58 determines the folder for storing the medical image in step S5. If the storage unit 57 is initialized when the power is turned on, a new folder is created based on the inspection information received in step S3. That is, when the communication unit 56 receives the inspection information, the communication unit 56 also gives the received inspection information to the recording data generation unit 52. When the examination information is input from the communication unit 56, the recording data generation unit 52 generates a patient ID and a folder corresponding to the examination ID, such as a patient folder or an examination folder, in the recording unit 53.

The images from the endoscopes 31 and 32 are supplied to the processors 15 and 23, respectively, and subjected to predetermined image signal processing to generate medical images. The processors 15 and 23 provide the generated medical images to the display devices 19 and 26 to display the endoscopic images, and also supply the medical image recording device 50. In this way, the medical image from the processor 15 or 23 is input to the video input unit 51 of the medical image recording apparatus 50. The video input unit 51 outputs the input medical image to the record data generation unit 52. When the operator or the like has not instructed recording, the record data generation unit 52 outputs the input medical image as it is to the external monitor (not shown) via the video output unit 54. Thereby, the medical image input to the medical image recording device 50 can be confirmed on the display screen of the monitor.

Here, for example, the operator operates the processors 15 and 23 to instruct the start of the recording of the medical image, or operates the recording start button (not shown) of the endoscopes 31 and 32 to record the medical image. It is assumed that the start is instructed or the operation/display unit 60 is operated to instruct the start of the medical image recording. If the AC power source is not cut off, the control unit 59 of the medical image recording apparatus 50 determines whether or not the process is transferred from step S6 to step S11 to perform recording, and the recording is started. The recording of the medical image input by the operation is started. That is, the control unit 59 controls the recording data generating unit 52 to generate recording data based on the input medical image. The recording data generation unit 52 sequentially supplies the generated recording data to the recording unit 53 and records it in the already created folder (step S12).

When the operator gives an instruction to end the recording of the medical image, the control unit 59 makes the recorded data into a file. In this way, the image file of the medical image is recorded in the patient folder.

Now, it is assumed that the operator stops the operation of the medical image recording apparatus 50 by cutting off the AC power supplied to the medical image recording apparatus 50. The power supply connection detection unit 64 monitors the power supply from the AC power supply to the power supply input unit 61 (step S6), and when it detects that the power supply has been cut off, it controls the power supply switching unit 62 to control the medical image recording apparatus. The backup power source from the backup power source unit 63 is selected as the power source to be supplied to the inside of 50 (step S7). When the power supply is turned on, the backup power supply unit 63 is supplied with the charging current for power storage from the power supply input unit 61, and the battery is charged. When the power supply is cut off, the power supply switching unit 62 supplies the backup power supply from the backup power supply unit 63 to each unit as an internal power supply.

During operation by the backup power supply, the control unit 59 terminates recording of a medical image that is being recorded, converts the medical image into a file, and stores the filed medical image in a corresponding folder. Further, the control unit 59 causes the storage unit 57 to hold the own device information (step S8). The control unit 59 determines whether or not the file formation of the medical image being recorded and the saving of the self-opportunity information have been completed (step S9). When the saving of information is completed, the control unit 59 controls each unit to execute the shutdown process (step S10). Thus, the medical image recording device 50 stops operating. The control unit 59 may cause the communication unit 56 to receive the inspection information and store the received inspection information in the storage unit 57 during the operation by the backup power supply.

Here, it is assumed that the operator restarts the operation of the medical image recording apparatus 50 by reapplying AC power to the medical image recording apparatus 50. When the power supply connection detection unit 64 detects that the power supply from the AC power supply to the power supply input unit 61 is restarted (step S1), the power supply connection detection unit 64 controls the power supply switching unit 62 to supply power to the inside of the medical image recording apparatus 50. The power source from the power source input section 61 is selected.

Immediately after the power is turned on, the control unit 59 controls the communication unit 56 to receive the inspection information from the processors 15 and 23 (step S2). The communication unit 56 gives the received inspection information to the operation determination unit 58. The operation determination unit 58 reads out the inspection information and the own device information stored before the power is cut off from the storage unit 57 (steps S3 and S4), and the read inspection information and the own device information and the communication unit 56 when the power is turned on. The operation determination is performed based on the received inspection information and the setting information read from the storage unit 57. The operation determination unit 58 determines a recording folder and whether recording is possible based on the operation determination result (step S5). The inspection information received by the communication unit 56 after the power is turned on is stored and stored in the storage unit 57 after the operation determination unit 58 reads the inspection information before the power shutdown from the storage unit 57.

Now, it is assumed that the self-device information indicates that the medical image was not being recorded when the power was cut off. In this case, the operation determination unit 58 sets each unit to the recording standby state. In addition, the operation determination unit 58 sets each unit to the recording continuing state when the own device information indicates that the medical image was being recorded when the power was cut off. That is, in this case, the operation determination unit 58 causes the control unit 59 to control the recording data generation unit 52 to generate the recording data of the medical image input via the video input unit 51.
The operation determination unit 58 performs operation determination for determining the recording folder by comparing the inspection information when the power is cut off and the inspection information when the power is turned on again, and based on this determination result, the folder of the medical image storage destination. To decide. If both the patient ID at the time of power-off and the examination ID are the same as the patient ID or the examination ID at the time of turning the power on again, the operation determination unit 58 gives an instruction to the control unit 59 to determine the patient ID or The recorded data of the created medical image is stored in the folder corresponding to the examination ID.

If at least one of the patient ID and the examination ID at the time of power-off differs from the patient ID or the examination ID at the time of power-on again, the operation determination unit 58 gives an instruction to the control unit 59 to generate a new patient ID. Alternatively, after creating a folder corresponding to the examination ID, the recorded data of the medical image is stored in the created folder.

Further, when the operation determination unit 58 cannot receive the patient ID and the examination ID at the time of power-off, it gives an instruction to the control unit 59 to open a folder corresponding to the new patient ID or examination ID. After the creation, the medical image recording standby state is entered.

Thus, as shown in the chart of FIG. 3, the operation determination unit 58 stores the record data of the medical image by comparing the inspection information stored when the power is cut off with the inspection information received when the power is turned on again. It is determined whether or not a new folder is created, and whether recording is restarted or a recording standby state is determined depending on whether or not the power is cut off during recording.

As described above, in the present embodiment, the inspection information is newly received when the power is turned on again, and a new folder is created by comparing the inspection information with the inspection information stored when the power is turned off. Determine whether to save the recorded data of the image. As a result, it is possible to prevent unintended mixing of data, and it is possible to save the record data of the medical image in the folder desired by the user.
Further, in the present embodiment, since it has a backup power supply, it is possible to perform control using the inspection information at the time of power shutoff, for example, even when there is own machine information changed immediately before power shutoff, Recording control that reflects the user's wishes is possible.

Even when the backup power source does not exist, the inspection information is updated at a predetermined timing, and the information at the time of updating is stored in the storage unit 57. Therefore, it is not possible to control using information at the time of power shutdown, but it is possible to perform recording control using information at the timing before power shutdown.

The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements within a range not departing from the gist of the invention in an implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some of all the constituent elements shown in the embodiment may be deleted.
