As described above, in the patient abnormality notification system 100 according to the present embodiment, when an abnormality occurs in the patient, the region for displaying the abnormal item is not abnormal so that the user can easily see the abnormal item of the patient. The display is performed in such a manner that it can be distinguished from the area in which the item is displayed.

  Next, with reference to FIG. 8, FIG. 14, and FIG. 15, the setting of patient information when performing patient abnormality determination in the patient abnormality notification system 100 according to the present embodiment will be described.

  In the patient abnormality notification system 100 according to the present embodiment, it is possible to determine whether or not a patient is in an abnormal state based on different criteria for each individual patient by setting patient information in advance for each patient. Is possible. The patient information of each individual patient can be confirmed and changed on the patient setting confirmation screen 900 shown in FIG. Patient information can be individually set and changed on the individual patient setting input screen 950 shown in FIG. Details will be described below.

  The patient setting confirmation screen 900 is displayed by selecting the “patient setting” button 602 shown in FIG. As shown in FIG. 14, the patient setting confirmation screen 900 displays a list of patient information of patients whose patient information is set. The items of patient information include “hospital room name”, “bed number”, “patient ID”, “patient name”, “hospitalization”, “nursing”, “sleeping”, and “getting out of bed”. In “hospitalization”, it is possible to set whether the patient is hospitalized or discharged. Further, in “Nursing”, it is possible to set whether or not the patient is to be monitored by the patient abnormality notification system 100 according to the present embodiment. Further, in “sleeping possible”, it is possible to set whether or not the patient's turning operation is detected as abnormal. In addition, in “Can get out of bed”, it is possible to set whether or not the patient detects the bed leaving operation as abnormal.

The patient information items further include “pulse upper limit”, “pulse lower limit”, “SpO ₂ lower limit”, “maximum blood pressure upper limit”, “minimum blood pressure lower limit”, “body temperature upper limit”, and “body temperature lower limit”. It is. By setting the numerical value of these items as the threshold of the normal range of the patient's biological information, it is determined that an abnormality has occurred in the patient when the patient's biological information is not within the set normal range, and the patient's abnormality It is possible for the patient abnormality notification system 100 to give a warning about the occurrence of this.

  Also, by selecting a “new registration” button 901, it is possible to newly set patient information on the individual patient setting input screen 950 shown in FIG. Also, by selecting the “change setting” button 902 in a state where a patient is selected, it is possible to change the patient information of the patient. Further, when the “setting complete” button 903 is selected, the change of the patient information becomes effective (the set numerical values and the like are stored in the hard disk 501d), and the screen is switched to the hospital room selection screen 600. Further, by selecting the “cancel” button 904, the change of the patient information is canceled and the screen is switched to the hospital room selection screen 600.

  In addition, the individual patient setting input screen 950 is configured to reflect the input numerical value or the like on the patient setting confirmation screen 900 and return to the patient setting confirmation screen 900 by selecting a “setting completed” button 951. Yes. Further, by selecting a “Cancel” button 952, the input numerical value or the like is not reflected on the patient setting confirmation screen 900, and the patient setting confirmation screen 900 is returned.

  FIGS. 16-18 is a flowchart for demonstrating the display process of the screen displayed on the display part of the patient abnormality notification system by this embodiment. Next, with reference to FIGS. 8-12 and FIGS. 16-18, the display process of the screen displayed on the display part of the patient abnormality notification system by this embodiment is demonstrated.

  First, when the power (not shown) of the centralized monitoring device 5 is turned on, the control unit 5a of the centralized monitoring device 5 initializes the control unit 5a (program initialization) in step S1 of FIG. When the centralized monitoring device 5 is turned on, the camera device 4 and the receiver 3 are also supplied with power through the LAN cable and the hub 6. When the initialization is completed, a hospital room selection screen 600 is displayed as a standby screen as shown in FIG. 8 in step S2. Moreover, the 1st portable transmitter 1 with which the patient was mounted | worn regularly transmits the patient's acceleration information and body temperature information with 1st ID information. Moreover, the 2nd portable transmitter 2 with which the patient was mounted | worn regularly transmits the patient's biological information with 2nd ID information. Further, the receiver 3 receives the information and transmits it to the centralized monitoring device 5 via the LAN cable and the hub 6.

  Next, in step S3, it is determined whether or not the control unit 5a of the centralized monitoring device 5 has received the first ID information, acceleration information, and body temperature information. If such information has not been received, this determination is repeated. If such information is received, in step S4, the control unit 5a calculates the position of the patient based on the acceleration information. In step S5, the control unit 5a determines the posture of the patient based on the acceleration information. Further, the control unit 5a determines whether or not the acceleration is abnormal by comparing the acceleration information with a preset threshold value.

In step S6, it is determined whether or not the control unit 5a of the centralized monitoring device 5 has received the _second ID information, heart rate information, blood pressure information, and SpO ₂ information. If such information has not been received, this determination is repeated. If such information is received, in step S7, the control unit 5a performs an abnormality determination process for determining whether an abnormality has occurred in the patient. This abnormality determination process will be described later in detail.

  In step S8, it is determined whether an abnormality has occurred in the patient. If it is determined that an abnormality has occurred in the patient through the abnormality determination process, an abnormality warning process is performed in step S9 for notifying the doctor or nurse of the patient's abnormality. This abnormality warning process will be described later in detail. Thereafter, the processes in steps S3 to S9 are repeated.

  If it is determined that no abnormality has occurred in the patient, it is determined in step S10 whether or not a patient selection has been accepted. That is, it is determined whether or not a patient has been selected in a patient selection dialog 610 (see FIG. 9) displayed by selecting a room on the hospital room selection screen 600 (see FIG. 8). When the selection of the patient is not accepted, the process proceeds to step S12 in FIG. When the selection of the patient is accepted, the patient status screen 700 (see FIG. 10) of the selected patient is displayed in step S11, and the posture state of the patient is displayed in the switching display area 750 of the patient status screen 700. Is displayed.

Thereafter, in step S12 of FIG. 21, it is determined whether or not the patient's posture state is displayed in the switching display area 750 of the patient state screen 700. As shown in FIG. 10, when the patient's posture state is displayed in the switching display area 750, in step S13, the body temperature information obtained in step S3, the patient position calculated in step S4, and the step The displayed screen (patient status screen) is updated based on the posture of the patient determined in S5 and the biological information (heart rate, blood pressure, and SpO ₂ ) obtained in step S6. Thereafter, the process proceeds to step S18.

  In step S12, when the patient's posture state is not displayed in the switching display area 750 (when vital information or a camera image is displayed in the switching display area 750, or the room selection screen 600 is displayed. In step S14, it is determined whether or not an instruction to display the posture state in the switching display area 750 has been received (the “posture” button 761 has been selected by the user). If this instruction is not accepted, the displayed screen (patient status screen 700 or hospital room selection screen 600) is updated in step S13. If an instruction to display the posture state is received, it is determined in step S15 whether or not the camera device 4 is operating. If the camera device 4 is not operating, the process proceeds to step S17. If the camera apparatus 4 is operating, an imaging stop instruction signal is transmitted to the operating camera apparatus 4 in step S16. Thereafter, in step S17, the posture state of the patient is displayed in the switching display area 750.

  In step S18, it is determined whether or not the patient's biological information is displayed in the switching display area 750 of the patient status screen 700. When the patient's biological information is displayed in the switching display area 750, the displayed screen (patient status screen 700) is updated in step S19 as in step S13. Thereafter, the process proceeds to step S24 in FIG.

  In step S18, when the patient's biological information is not displayed in the switching display area 750 (when the posture state or the camera image is displayed in the switching display area 750, or the room selection screen 600 is displayed. If YES in step S20, it is determined whether an instruction to display biometric information in the switching display area 750 has been received (the “vital” button 762 has been selected by the user). If this instruction is not accepted, the displayed screen (patient status screen 700 or hospital room selection screen 600) is updated in step S19. When an instruction to display biometric information is received, the same processing as in steps S15 and S16 is performed in steps S21 and S22. Thereafter, in step S23, the biological information of the patient is displayed in the switching display area 750.

  Thereafter, in step S24 of FIG. 18, it is determined whether or not a camera image is being displayed in the switching display area 750. If a camera image is being displayed in the switching display area 750, the process proceeds to step S29. Further, when the camera image is not being displayed in the switching display area 750 (when the posture state or vital information is displayed in the switching display area 750 or when the hospital room selection screen 600 is displayed), the step is performed. In S25, it is determined whether or not an instruction to display a camera image in switching display area 750 has been received ("camera" button 763 has been selected by the user). If an instruction to display a camera image is not accepted, the displayed screen is updated in step S32.

  When an instruction to display a camera image is received, in step S26, the patient's position calculated in step S4 in FIG. 16 is compared with the respective positions of the plurality of camera devices 4, thereby giving the patient The closest camera device 4 is identified. Thereafter, in step S27, an imaging start signal is transmitted to the identified camera device 4, and in step S28, the display of the switching display area 750 is switched to the camera image.

  Further, in the camera device 4 that has received the imaging start signal, the camera device 4 starts imaging the patient. In addition, camera image data including a patient image is sequentially transmitted to the centralized monitoring device 5. The centralized monitoring device 5 determines whether camera image data has been received in step S29. This determination is repeated when camera image data is not received. If camera image data is received, it is determined in step S30 whether a camera operation has been accepted. That is, it is determined whether or not the user has instructed to change the imaging range and the magnification of the camera by operating the slide bars 751 to 753 (see FIG. 12).

  If no camera operation is accepted, the process proceeds to step S32. If a camera operation is accepted, in step S31, a signal instructing the operation instructed by the user is transmitted to the camera device 4 that is imaging. The camera device 4 receives the signal and changes the imaging range and magnification of the camera.

  In step S32, the displayed screen (patient status screen 700) is updated based on the camera image data transmitted from the camera device 4.

  Thereafter, in step S33, it is determined whether or not the hospital room selection screen 600 is displayed. If the hospital room selection screen 600 is displayed, the process proceeds to step S3 in FIG. When the patient room selection screen 600 is not displayed (when the patient state screen 700 is displayed), it is determined in step S34 whether an instruction to display the patient room selection screen 600 has been received. That is, it is determined whether or not the “Return” button 764 on the patient status screen 700 has been selected. If the instruction to display the hospital room selection screen 600 is not accepted, the process proceeds to step S3 in FIG.

  When an instruction to display the room selection screen 600 is received, the same processing as in steps S15 and S16 is performed in steps S35 and S36, and the room selection screen 600 is displayed in step S37. The Thereafter, the process proceeds to step S3. Thereafter, steps S3 to S37 are repeated.

  In the patient abnormality notification system 100 according to the present embodiment, the display of the patient state screen 700 is updated at any time by repeating step S3 to step S37, so that the user can check the patient state in real time. is there.

  FIG. 19 is a flowchart for explaining details of the abnormality determination processing in step S7 shown in FIG. Next, the abnormality determination process will be described with reference to FIG.

In the abnormality determination process, first, in step S40, normal range information of a patient who performs abnormality determination is read. That is, the threshold values of biological information (heart rate, blood pressure, SpO ₂ and body temperature) are read with reference to the patient information stored in the hard disk 501d.

  Then, it is determined whether or not the read normal range information, the acceleration information obtained in step S3, and the biological information obtained in step S6 are abnormal. Specifically, in step S41, it is determined whether or not the acceleration has deviated from the normal range. When the acceleration does not deviate from the normal range (when the acceleration is within the normal range), the process proceeds to step S44. In step S41, if the acceleration deviates from the normal range, it is determined whether the acceleration abnormality is due to falling or falling from a bed or the like. In this case, it is determined to fall when the patient's posture changes from standing or walking to a supine position, and when the patient changes from being on the bed to being under the bed, it is determined to fall. . If it is determined that the vehicle has fallen, the abnormal state “falling” is stored in step S42. If it is determined that the vehicle has fallen, the abnormal state “falling” is stored in step S43.

  Thereafter, in step S44, it is determined whether or not the body temperature deviates from the normal range. When the body temperature does not deviate from the normal range (when it is within the normal range), the process proceeds to step S46. If the body temperature deviates from the normal range, the abnormal state “body temperature” is stored in step S45.

  Thereafter, in step S46, it is determined whether or not the heartbeat deviates from the normal range. If the heart rate does not deviate from the normal range (if within the normal range), the process proceeds to step S48. If the heartbeat deviates from the normal range, the abnormal state “heartbeat” is stored in step S47.

  Thereafter, in step S48, it is determined whether or not the blood pressure deviates from the normal range. If the blood pressure does not deviate from the normal range (if within the normal range), the process proceeds to step S50. If the blood pressure deviates from the normal range, the abnormal state “blood pressure” is stored in step S49.

Thereafter, in step S50, it is determined whether SpO ₂ is out of the normal range. When SpO ₂ does not deviate from the normal range (when it is within the normal range), the abnormality determination process ends. If SpO ₂ deviates from the normal range, the abnormal state “SpO ₂ ” is stored in step S 51, and the abnormality determination process ends.

As described above, in the abnormality determination process, each item of acceleration, body temperature, heart rate, blood pressure, and SpO ₂ is compared with the set normal state value to determine whether or not each item is abnormal. In addition, items determined to be abnormal are stored.

  20 and 21 are flowcharts for explaining details of the abnormality warning process in step S9 of FIG. Next, details of the abnormality warning process will be described with reference to FIGS. 13, 20, and 21.

  In the abnormality warning process, first, in step S60 of FIG. 20, an abnormality is detected from the first ID information and the second ID information corresponding to the data (acceleration information, body temperature information, etc.) determined to be abnormal in the abnormality determination process described above. The resulting patient is identified. That is, by referring to the table T1 stored in the hard disk 501d, the patient wearing the first portable transmitter 1 corresponding to the first ID information and the second portable transmitter 2 corresponding to the second ID information. (Patient ID) is specified.

  In step S61, the position of the patient calculated in step S4 of FIG. 16 is compared with the position of each of the plurality of camera apparatuses 4, thereby specifying the camera apparatus 4 that is closest to the patient. Thereafter, in step S62, an imaging start signal is transmitted to the identified camera device 4. Thereafter, in step S63, the abnormality warning screen 800 (see FIG. 13) is displayed, and the “camera” button 863 is selected, so that the camera image is displayed in the switching display area 850. Can be switched. In this abnormality warning screen 800, an item determined to be abnormal in the above-described abnormality determination process is highlighted so as to be distinguishable from other items.

  In the camera device 4 that has received the imaging start signal, the shielding plate 4c of the camera device 4 moves to the exposure position, and imaging of the patient is started by the exposed camera 4a. In addition, camera image data including a patient image is sequentially transmitted to the centralized monitoring device 5. The centralized monitoring device 5 determines whether camera image data has been received in step S64. This determination is repeated when camera image data is not received. If the camera image data is received, the abnormality warning screen 800 is updated based on the received camera image data in step S65.

Thereafter, in step S66 of FIG. 21, it is determined whether or not the patient posture state is displayed in the switching display area 850 of the abnormality warning screen 800.

If this instruction is not accepted, the displayed screen (abnormality warning screen 800 or hospital room selection screen 600) is updated in step S67. If an instruction to display the posture state is received, the posture state of the patient having an abnormality is displayed in the switching display area 850 in step S69.

  In step S70, it is determined whether or not the patient's biological information is displayed in the switching display area 850 of the patient status screen. When the patient's biological information is displayed in the switching display area 850, the displayed screen (abnormality warning screen 800) is updated in step S71 as in step S67. Thereafter, the process proceeds to step S74.

  In step S70, when the patient's biological information is not displayed in the switching display area 850 (when the posture state or the camera image is displayed in the switching display area 850, or the room selection screen 600 is displayed. If YES in step S72, it is determined in step S72 whether an instruction to display biometric information in the switching display area 850 has been received (the “vital” button 862 has been selected by the user). If this instruction is not accepted, the displayed screen (abnormal warning screen 800 or hospital room selection screen 600) is updated in step S71. If an instruction to display biometric information is received, in step S73, the biometric information of the patient having an abnormality is displayed in the switching display area 850.

  Thereafter, in step S74, it is determined whether or not a camera image is being displayed in the switching display area 850. If a camera image is being displayed in the switching display area 850, the process proceeds to step S75. When the camera image is not being displayed in the switching display area 850 (when the posture state or vital information is displayed in the switching display area 850 or when the patient room selection screen 600 is displayed), the step is performed. In S76, it is determined whether or not an instruction to display a camera image in switching display area 850 has been received ("camera" button 863 has been selected by the user). If the instruction to display the camera image is not accepted, the displayed screen is updated in step S75. If an instruction to display a camera image is received, in step S77, the camera image of the patient having an abnormality is displayed in the switching display area 850.

  Thereafter, in step S78, it is determined whether or not an instruction to stop the warning display has been given by the user. That is, whether or not the “return” button 864 of the abnormality warning screen 800 has been selected, whether or not the “alarm stop” button 865 has been selected, or one minute has elapsed since the abnormality warning screen 800 was displayed. It is determined whether or not. If there is no instruction to stop the warning display, the process proceeds to step S64 in FIG. If there is an instruction to stop the warning display, in step S79, an imaging stop instruction signal is transmitted to the camera device 4 that is operating (under imaging).
