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 microfluidic sensor. By placing the microfluidic sensor inside the wristband, when it is close to the position of the wrist artery, the microfluidic sensor senses the pressure change of the wrist artery and changes its resistance value. The fluid sensor is externally connected to an AC voltage signal. As the resistance changes, the output voltage of the microfluid sensor also changes. After being amplified by the amplifier and filtered by the filter module, it is input to the comparator, and the output voltage is compared with the preset threshold. , and then judge the beating of the pulse, and use the counter to count the beating of the pulse at the same time, input the statistical results per unit time to the control module, and control the display of the display module and the reception of the terminal, with high test accuracy and small system size. Strong expandability, suitable for carrying around.

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...
