The pulse detection device 2 is worn on the wearer's chest and the emergency signal generator 3 is worn on the wearer's wrist. In this state, the pulse detection device 2 continuously detects and outputs the wearer's heartbeat signal while the wearer is borrowing.

The heartbeat signal is obtained by detecting a potential difference through a pair of electrodes 21 in the pulse detection device 2. The pair of electrodes 21 are mounted on the chest of the wearer, and the heartbeat signal (R wave) according to the heartbeat can be expressed by a potential difference. Therefore, the voltage detected from the pair of electrodes 21 is input to the amplifier / filter section 26 so that the potential difference is detected, amplified, and then the noise signal is removed and output. The output of the amplification / filter section 26 is input to the waveform shaping section 27 and converted into a logic signal according to high / low. In this way, the pulse signal using the potential difference is detected (step 100).

In step 190, the medical sensor 6, the hospital, 119 (7), and the relative 8 which are connected according to the emergency signal generation are called to notify the occurrence of an emergency situation. Therefore, in this step, the emergency occurrence message stored in advance is sent together.

Meanwhile, if the unique code of the emergency signal input in step 170 and the recognized unique code do not match, the emergency signal reception standby state is maintained (step 180).

When it is determined that the pulse rate calculated in step 130 is not abnormal (step 150), the microprocessor 33 in the emergency signal generator 3 confirms the transmission request of pulse data from the data collector 4 (step 200 steps). That is, in step 200, in order to prevent the collision of the transmission data according to the emergency signal generation and the data according to the transmission request of the pulse data, the pulse data transmission is set when abnormality does not occur.

When there is a request for sending pulse data in step 200, the pulse data stored in the memory 34 is transmitted to the data collector 4 (step 210).

The pulse data transmitted in step 210 is received through the high frequency receiver 41 in the data collector 4 and stored in the memory 47 under the control of the controller 44. Pulse data stored in the memory 47 is transmitted to the external device through the serial communication unit 46 according to the request of the external device.
