Embodiment Construction
[0027] The high anti-interference pulse monitoring device of the invention can sense the one-dimensional and two-dimensional pulse pulse pressure of human arteries, and can effectively reduce other interference signals.
[0028] According to an embodiment of the present invention, the high anti-interference pulse monitoring device includes at least one multi-probe main sensor and one relatively isolated auxiliary sensor. The output of each high anti-interference pulse detector is the voltage signal of the main sensor and the auxiliary sensor in anti-phase series. The high anti-interference pulse detector can be a wristband, armband, chest strap, leg strap, mattress, seat cushion and any device that can touch the human body and be fixed near the artery.
[0029] Each probe senses the arterial pressure independently, and the pulse signal detected by the probe dot matrix composed of multiple probes is superimposed on the main sensor; Superposition can be offset to form a high si...
