Physiological signal sensing device

Abstract

The invention provides a physiological signal sensign device which comprises the components of at least one first Doppler sensor, at least one second Doppler sensor, at least one first amplifying and filtering unit, at least one second amplifying and filtering unit, a processor and a transmitting unit, thereby sensing physiological information of body, wherein the first Doppler sensor and the second Doppler sensor are used for different body positions and generate and transmit a first physiological sensing signal and a second physiological sensing signal to the first amplifying and filtering unit and the second amplifying and filtering unit. Through appropriate amplifying, filtering and signal conversion processing, a first digital sensing signal and a second digital sensing signal are generated. The processor performs digital signal processing for generating first physiological information and second physiological information. Finally the first physiological information and the second physiological information are transmitted to outside through the transmitting unit. The first Doppler sensor and the second Doppler sensor can respectively abut against carotid artery and clavicle for sensing heartbeat rate and breathing rate.

AI Technical Summary

Problems solved by technology

This measurement method needs to use a long connecting wire to connect the electrode pad and the electronic device, which is quite inconvenient for the user, because the simple body movement will be disturbed if it is not tight, and the body movement will also affect the measurement accuracy, so generally you can only lie flat or sit quietly until the end of the measurement

Furthermore, when the electrode sheet is first attached to the body, the user will feel cold and uncomfortable due to the temperature difference with the body temperature, especially for young children or the elderly
