<p>PURPOSE:To provide an emergent aid system whereby an aged person, a patient, etc., detects the pulse, blood pressure, temperature and the like, finds the abnormality of his or her body, generates emergency waves thereby to inform a first-aid party of his or her place. CONSTITUTION:A sensor which detects one, or two or more of the pulse, blood pressure and temperature can be built in or connected to an emergent aid system 10. The aid system 10 has a transmitting device 11 like a wrist watch with a transmitter of very weak radio waves thereinside, a relay radio device 13 for receiving the very weak radio waves and radio stations 14-17 for detecting the position of the radio device 13 by detecting emergency radio waves. The abnormal state of a person with the transmitting device 11 is detected by one or two or more of the pulse, blood pressure and temperature, whereby the transmitter of the transmitting device 11 is activated to send very weak radio waves. The very weak radio waves are received by the relay radio device 13 and consequently, comparatively intense emergency radio waves including an independent identification symbol are sent out. The emergency radio waves are received by the radio stations 14-17, so that the place of the person with the transmitting device 11 is detected.</p> |
