Problems solved by technology

However, among the existing pulse monitoring systems, few are used to monitor the pulse alone, and most of them are systems for monitoring multiple physical indicators, which cannot be carried around and are not suitable for the needs of special people.
In addition, the sensors used in existing pulse monitoring systems are not as accurate as microfluidic sensors

Abstract

The invention discloses a pulse monitoring system based on a micro fluid sensor. The micro fluid sensor is arranged on an inner side of a wristband, the micro fluid sensor inducts a pressure change of a waist artery when approaches the position of the waist artery, the resistance value is changed, an alternating voltage signal is connected with the outer portion of the micro fluid sensor, with the resistance value changes, an output voltage of the micro fluid sensor changes, after an amplification by an amplifier and a filtering by a filtration module are conducted, the output voltage is input in a comparator, the output voltage and the predetermined threshold level are compared, and then the throb of a pulse is determined and at the same time a counter counts the throb of the pulse, the statistic result is input in unit time in a control module, so that the display of a display module and the reception of a terminal are controlled; the test precision is high, the bulk of the system is small, the extendibility is strong, and the system is suitable for carrying.

Description

technical field [0001] The invention belongs to the technical field of health monitoring, and more specifically relates to a pulse monitoring system based on a microfluidic sensor. Background technique [0002] With the improvement of people's living standards, the proportion and number of people who are sick are also increasing. Timely prevention is the most effective and direct method. [0003] Traditional Chinese medicine is a unique medical art in China. It is a discipline that studies human physiology, pathology, and disease diagnosis and prevention. Traditional Chinese medicine can judge the location and severity of a patient's disease through the beating frequency, speed, and severity of the pulse. It is no exaggeration to say that people's movement, stillness, emotions, and diseases will affect the beating of the pulse, and each different situation will affect the pulse accordingly. Chinese medicine diagnoses diseases from the slight difference in the pulse. Especia...
