[0040]
The first transmitter 46 converts the serial signal input from the multiplexer 44 into an infrared signal and transmits it. When an echo signal is input from the echo signal storage unit 50, the echo signal is converted into an infrared signal and transmitted. The infrared signal transmitted from the first transmitter 46 is received by the second receiver 56 of the communication terminal 26 (see FIG. 3) provided indoors.

On the other hand, the terminal communication unit 60 receives a signal from the monitoring device 32 sent via the communication line 28 and outputs the signal to the second transmitter 58.
[0044]
The second transmitter 58 converts the signal sent from the monitoring device 32 side into an infrared signal and transmits it to the first receiver 52 (see FIG. 2). Here, in this embodiment, transmission / reception between the first transmitter 46 and the second receiver 56 and transmission / reception between the second transmitter 58 and the first receiver 52 use radio waves instead of infrared rays. Then, transmission / reception may be performed. In this embodiment, the communication line 28 is a telephone line as a public line.

The monitoring device 32 is provided with a setting unit 82 made up of a trackball or a keyboard. A user such as a doctor can use the setting unit 82 to input an instruction related to the operation of the measurement unit 24 to the center control unit 64. Here, the center control unit 64 controls the operation of the entire monitoring device 32. The center control unit 64 outputs a signal based on the instruction or the like to the center communication unit 62.
[0047]
The center communication unit 62 sends the signal to the terminal communication unit 60 via the communication line 28. The center communication unit 62 receives a serial signal and an echo signal from the terminal communication unit 60. The center communication unit 62 outputs the input serial signal to the demultiplexer 66.
[0048]
The demultiplexer 66 is a distributor, and separates and restores the serial signal time-division multiplexed in the multiplexer 44 of FIG. 2 into the original processing signal from each sensor.
[0049]
The sensor signal processing unit 68 includes an electrocardiogram signal processing unit 68a, an electroencephalogram signal processing unit 68b, a blood pressure signal processing unit 68c, a pulse signal processing unit 68d, and a body temperature signal processing unit 68e.

The echo signal from the center communication unit 62 is first input to the echo signal processing unit 72. The echo signal processing unit 72 includes a known circuit such as a detection circuit or a Doppler arithmetic circuit, for example, and performs signal processing necessary for forming an ultrasound image. The image forming signal after the signal processing is output to the image forming unit 74.
[0051]
The image forming unit 74 forms a biological information image representing the health state of the subject 10 based on the image forming signal corresponding to each sensor from the sensor signal processing unit 68. Further, based on the image forming signal from the echo signal processing unit 72, an ultrasonic image such as B mode, M mode, or Doppler mode is formed.

Each stored image signal can be output to the display 76 as necessary, and can be utilized for diagnosis by a doctor or the like. The recorder 78 is, for example, a DVD, but may be another VTR.
[0053]
Next, the operation of the measurement unit 24 will be described with reference to FIGS.
[0054]
FIG. 4 is an explanatory diagram showing an operation process of the measurement unit 24. In the present embodiment, a case will be described as an example where a cardiac echo is obtained when an abnormality of the heart occurs while the subject is awake.
[0055]
The sensor signal processing control unit 42b in FIG. 2 instructs the measurement of each sensor (S100). Thereby, electrocardiogram, electroencephalogram, blood pressure, pulse and body temperature are measured (S102). The measured signals from these sensors are temporarily stored and transmitted from the measurement unit 24 (S104). Thereby, signals from these sensors are output as electrocardiogram, electroencephalogram, blood pressure, pulse and body temperature by the monitoring device 32 of the centralized management center 30 (see FIG. 1), and doctors and the like monitor their biological information. Can do.
[0056]
In S106, it is determined whether the subject is awake based on the electroencephalogram. Specifically, it is determined whether or not the patient is in the awake state by comparing and comparing the measured brain wave signal waveform and the brain wave signal waveform in the awake state. If it is determined in S106 that the user is not in the awake state, the process returns to S100, and measurement of each sensor is performed. If it is determined that the user is awake, the process proceeds to S108.
[0057]
In S108, whether or not the subject is likely to be in an abnormal state is individually determined for each sensor. In the individual determination in each sensor, for example, the individual determination result is output by comparing the threshold value of the abnormal state of the sensor signal stored in advance in the ROM or the like with the signal waveform of each sensor measured in S102. Is done.
[0058]
In S110, it is comprehensively determined whether or not the subject is in an abnormal state based on each individual determination result obtained in S108. Specifically, for example, based on each individual determination result output in S108, the overall determination of the abnormal state is performed by, for example, an AND condition. If the overall determination result is not an abnormal state, the process returns to S100 and the measurement of each sensor is performed. On the other hand, if the comprehensive determination result is an abnormal state, the process proceeds to S112.
[0059]
In S112, an ultrasonic wave is transmitted from the probe 12. The probe 12 receives the echo of the heart and outputs an echo signal. In S114, the echo signal output from the probe 12 is temporarily stored in the memory (echo signal storage unit 50 in FIG. 2) and transmitted.
[0060]
According to the present embodiment, the biological information of the subject is transmitted to the monitoring device 32 side (see FIG. 1), and the doctor or the like can always grasp the health condition of the subject from the biological information. Here, when the subject is in a normal state, the health condition is monitored by a sensor, and when the subject falls into an abnormal state, the probe automatically operates to diagnose an ultrasound image at the time of the attack. can do. Therefore, driving of the probe can be minimized. Thereby, unnecessary deterioration of the ultrasonic vibration element can be suppressed and unnecessary power consumption can be suppressed.
[0061]
FIG. 5 is a process explanatory diagram conceptually showing another operation process of the measurement unit 24. The sensor signal processing control unit 42b in FIG. 2 instructs measurement of body temperature, pulse and blood pressure (S200). Thereby, they are measured (S202).
[0062]
In S204, it is individually determined for each sensor signal whether or not the subject is likely to be in an abnormal state. In S206, it is comprehensively determined whether or not the subject is in an abnormal state based on the individual determination results obtained in S202. If the overall determination result is not an abnormal state, the process returns to S200, and the measurement by each sensor is performed in S202. On the other hand, if the comprehensive determination result is an abnormal state, the process proceeds to S208.
[0063]
In S208, the body temperature signal, the pulse signal, and the blood pressure signal in the abnormal state are temporarily stored in the memory (the sensor signal storage unit 40 in FIG. 2) and transmitted. Thereby, doctors etc. can grasp these abnormal living body information.
[0064]
When an abnormal state is determined in S206, an electrocardiogram signal is measured (S210), and probe transmission / reception is executed, and necessary signal processing is performed (S214).
[0065]
The electrocardiogram measured in S210 is individually determined in the electrocardiogram signal determination unit 38a whether or not there is a possibility of an abnormal state (S212). On the other hand, individual determination is also performed on the echo signal subjected to signal processing in S214 (S216).
[0066]
In the comprehensive determination in S218, the comprehensive determination is performed for the abnormal state based on the individual determination results obtained in S212 and S216. In S218, when the comprehensive determination result indicating that there is no abnormal state is output, the process returns to S200. On the other hand, if a comprehensive determination result indicating an abnormal state is output, the process proceeds to S220.
[0067]
In S220, the electrocardiogram signal and the echo signal are temporarily stored in the memory (the sensor signal storage unit 40 and the echo signal storage unit 50 in FIG. 2) and transmitted. Thereby, a doctor etc. can monitor the image of an ultrasonic wave and an electrocardiogram.
[0068]
When it is determined in S218 that the state is abnormal, brain wave measurement is performed (S222). Based on the electroencephalogram signal measured in S222, it is determined again whether or not the subject is in an abnormal state (S224).
[0069]
If it is determined in S224 that there is no abnormal state, the process returns to S200, and if it is determined that the state is abnormal, the process proceeds to S228 (S226).
[0070]
When the comprehensive determination result in S226 is a result that it is not an abnormal state, it returns to S200 and the subsequent steps are performed.
[0071]
As described above, in the case of an abnormal state or when there is a possibility of an abnormal state, different measurements can be performed step by step according to the necessity. Therefore, in the portable measurement unit 24, unnecessary transmission / reception of ultrasonic waves, signal processing, data storage, and data transmission can be prevented. As a result, power consumption of the battery 54 (see FIG. 2) can be suppressed, and the health condition of the subject can be monitored for a long time.
[0072]
There is a correlation between the electrocardiogram signal and the echo signal of the heart according to the motion of the heart. For example, in sleep states, it is known that biological information such as brain waves, blood pressure, body temperature, pulse, and electrocardiogram are correlated with each other. Therefore, by comparing these sensor signals and echo signals with each other, a doctor or the like can check whether each sensor or probe is not dropped from the appropriate part of the subject or is properly arranged. Is possible.
[0073]
In addition, it is good also as a structure which makes the subject 10 carry GPS, and the structure which issues the vehicle calling signal which calls an ambulance in S208, S218, or S228 is provided in the measurement unit 24.
