Abstract
A non-contact blood pressure measurement system and a non-contact blood pressure value calculation method thereof are disclosed. The non-contact blood pressure measurement system includes a measurement module, a signal processing module, and a calculation module. The measurement module measures a physiological signal of a subject being tested in a non-contact manner. The signal processing module is used to obtain a forward pressure wave and a backward pressure wave according to the physiological signal of the subject being tested. The calculation module is used to find out a reflected pulse transit time between the forward pressure wave and the backward pressure wave so as to substitute the reflected pulse transit time and a plurality of correction parameters into a blood pressure algorithm formula to calculate an estimated diastolic blood pressure and an estimated systolic blood pressure of the subject being tested.
