  As shown in FIG. 1, the biotelemetry system according to the present invention includes a biological information recording device 1 (1a, 1b,...) Carried by a plurality of users (A, B,...) And an external display device 2. Is done. The biometric information recording device 1 can communicate with the external display device 2 wirelessly. Note that the biological information recording apparatus 1 can measure and record biological information even if the biological information recording apparatus 1 does not always communicate with the external display device 2.

<External display device>
As shown in FIG. 2, the external display device 2 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, an input unit 14, a communication interface 15, and a graphic processing unit 16. , And a display unit 17, each connected by an internal bus. The communication interface 15 is connected to the biological information recording apparatus 1 by wireless communication directly or via the communication network 3, and transmits / receives biological information.

  The external display device 2 can individually identify the biometric information recording device 1 by authenticating using the unique information of the biometric information recording device 1, for example.

  The biological information recording device 1 and the external display device 2 can be connected via a relay device 4 and a communication network 3 as shown in FIG. For example, one relay device may be installed in a room, and the biological information of a plurality of biological information recording devices 1 existing in the room may be collected and transmitted to the external display device 2 via the communication network 3. Thereby, even if the biometric information recording device 1 and the external display device 2 are separated to such an extent that they cannot communicate, the biometric information of the patient can be monitored in real time.

  The biological information analysis function of the external display device 2 is entirely realized by software, and the analysis information can be displayed on the portable information terminal or the display function can be transplanted to a terminal device or the like equipped with a different OS. Is possible. Therefore, it is possible to display biometric information on a small and light external display device of about 5 inches such as a so-called smartphone without requiring a conventional huge center device. As the external display device, for example, a personal computer, a mobile phone, a tablet computer, or the like may be used.

  FIG. 4 is a diagram illustrating an example of a display screen when a personal computer is used as the external display device 2, for example. The display screen 20 of the personal computer includes two display frames 21a and 21b, biometric information basic information 22 (for example, a display mode indicating real-time display or past log display, a biometric information recording apparatus ID, a user name, and display information. As a result of analysis by the biological information analysis function, heart rate information 23, temperature information 24, posture information 25, and posture image 26 are displayed.

  All the biological information received from the biological information recording apparatus 1 is displayed on the display screen 20. In FIG. 4, as an example, the biological information received from the two biological information recording devices 1 is displayed in the display frames 21a and 21b. When biometric information is received from more biometric information recording apparatuses 1, the display frames 31a to 31j can be automatically adjusted to be displayed on one screen by reducing the size of each of the display frames 31a to 31j as shown in FIG.

  A heart rate information display area 23 is provided at the top of the display frame 21a, and a temperature information display area 24 is provided at the center. An electrocardiogram waveform and a heart rate are displayed in the heart rate information display area 23. In FIG. 4, “73” is displayed as the heart rate. In addition, the skin temperature is displayed in the temperature information display area 24. In FIG. 4, “36.5 ° C.” is displayed as the skin temperature.

  At the bottom of the display frame 21a, posture information 25 and a posture image 26 are displayed. From the orientation of the posture image 26, it is possible to know in what posture the user is in the heart rate information and temperature information displayed on the display screen 21a. For example, in the posture image 26 of FIG. 4, it can be seen that the biometric information is measured while the user is lying down.

  The posture information 25 is measured by a three-axis gyro sensor. For example, as shown in FIG. 6, when a change in angle on the XZ axis and the YZ axis is detected by a three-axis gyro sensor, it can be determined that the user has turned over. In this case, for example, an angle change threshold value (for example, 90 °) is set in advance on the application software, and when an angle change exceeding the threshold value occurs, it can be determined that the person has turned over. Thus, for example, when an elderly person is sleeping on the bed, there is a risk of falling from the bed by hitting the bed. Therefore, if the supervisor can grasp the turn, an accident can be prevented in advance.

  Similarly, it is possible to grasp whether the user is standing (or sitting) or sleeping from the change in angle on the XZ axis and the YZ axis. For example, when the state of standing for a long time continues despite the bedtime, the supervisor can also grasp the possibility that a user's habit has occurred. In addition, when the user is sleeping for a long time in spite of the daytime activity time, the supervisor can grasp the possibility that the user has fallen for some reason.

  FIG. 5 is a diagram of a display screen displaying biometric information transmitted from a plurality of biometric information recording devices. The display screen 30 includes display frames 31a to 31f and 31h to 31j related to the respective biological information recording devices, and an alert display frame 31g that is displayed when the external display device 2 determines that there is an abnormality as a result of analyzing the biological information. Prepare.

  The biological information analysis function of the external display device 2 is preferably a function that holds, for example, a numerical value in a range that the external display device 2 regards as normal for biological information as a threshold value, and compares the numerical value of the biological information with the threshold value. . When the numerical value of the biological information exceeds the threshold, the display frame related to the biological information recording apparatus that transmitted the target biological information is changed to the alert display frame 31g. The alert display frame 31g is, for example, a display frame color changed, a background color changed, or the like. Thereby, it is preferable that the monitor of the external display device 2 can immediately grasp the occurrence of the abnormal situation. Further, a sound may be output simultaneously with the alert display.

  For example, when a threshold value is used for the biological information analysis function of the external display device 2, the external display device 2 preferably includes an input device for changing the threshold value and has an update function for updating the threshold value. Furthermore, it is preferable that a threshold value can be set for each biological information recording device according to the sex, age, and health status of the user. Or you may set according to a doctor's diagnosis.
