Abstract
The vital sign detection device of the present invention includes one or more sensors, which can detect a plurality of vital sign signals of a test subject in a non-contact manner, and output corresponding a plurality of vital sign information, thereby achieving fast and accurate vital sign detection. The invention also relates to a combined multi-functional detection device, which includes a camera, a radar sensor, an infrared sensor and a sensor driving unit, used for measuring vital signs. The invention also provides a non-contact blood pressure measurement method and device. The method includes receiving radar echoes and video signal streams at first and second parts, extracting first and second pulse wave signals therefrom, obtaining a measured pulse wave transit time, matching the measured pulse wave transit time with a reference pulse wave transit time, and obtaining a blood pressure value.
