HEALTH CARE SYSTEM USING SMART WATCH

The present invention relates to a health care system using a smart watch, which can measure a pulse rate or pulse wave of a human body using a watch of a user, and can check health on the basis of the measured pulse rate. In the smart watch (10) which is worn in the body of the user, and outputs time and images on a screen. The smart watch (10) includes: a pulse rate measurement member (30) which measures the pulse rate of a human body; and a pulse rate management member (40) which manages pulse rate data measured in the pulse rate measurement member (30) and outputs the pulse rate data to the display (20). The pulse rate measurement member (30) includes a pulse rate measurement part (31) which gathers acoustic sound generated by the pulse rate. The pulse rate measurement part (31) includes: a sound collection part (32) which is formed on a rear side of the smart watch (10) concavely, and collects vibration generated in an organ of the human body; a sensor part (33) which is located in a concave center of the sound collection part (32), and checks the pulse rate data by amplifying the vibration collected in the sound collection part (32), and transmits the pulse rate data to the pulse rate management member (40); and a microphone (34) which checks acoustic wave data by amplifying the sound collected in the sound collection part of the pulse rate measurement part and then transmits the acoustic wave data to an acoustic wave management member (400). The pulse rate measurement part (31) further includes the acoustic wave management member (400) which manages the acoustic wave data measured in the microphone (34) of the pulse rate measurement member (30), and outputs the acoustic wave data to the display (20).
