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...

Abstract

The invention relates to a pulse detector with high interference resistance. The pulse detector with high interference resistance comprises two sensors in an inverted series connection mode, wherein a certain interval is maintained between the two sensors by utilizing a high-electricity and vibration insulation degree structure; the induction surface of one main sensor is provided with multiple probes which are arranged at preset intervals; the multiple probes transmit the pulse signals which are independently detected to the induction surface of the main sensor; the pulse signals received bythe induction surface of the main sensor are superposed by the signals detected by each probe; the pulse signals induced by the other auxiliary sensor in the inverted series connection mode are relatively weak because of the insulation action of the high-electricity and vibration insulation degree structure; and other interference signals induced by the two sensors with the same physical structure have the same strength and the opposite directions, thereby obtaining the pulse signals with basically counteracted interference, high signal-to-noise ratio, stability, reliability and insensitive positions after superposition. A reliable 24-hour pulse real-time monitoring system which can be actually applied in daily life can be established by utilizing the pulse detector with high interferenceresistance.

Description

technical field [0001] The invention relates to a high anti-interference pulse detector capable of monitoring vital signs of a human body. Background technique [0002] It is one of the most basic diagnostic methods for doctors to determine the health status of a person by detecting the pulse, such as heart rhythm, pulse condition and blood pressure. This is because the blood circulation system is the basic life system of the human body, and the pulse is closely related to life. [0003] Traditional Chinese medicine uses fingers to make pulse diagnosis. This operation obviously depends on the doctor's personal experience, and it is difficult to ensure consistency. Therefore, this diagnosis method is very subjective and lacks rigorous scientificity. Therefore, although the pulse condition is very important for diagnosis, doctors can only qualitatively describe the pulse condition based on what they feel with their fingers, and give a vague diagnosis. [0004] With the devel...
