Dynamic blood pressure monitoring system and dynamic blood pressure monitoring method based on radial artery biosensor technology

Abstract

The invention provides a dynamic blood pressure monitoring system and a dynamic blood pressure monitoring method based on a radial artery biosensor technology. The dynamic blood pressure monitoring system comprises a main processor, a watch and a biosensor arranged in the watch. The biosensor comprises a radial artery biosensor embedded in a watch belt, a stainless steel electrode embedded in the bottom of the watch and a stainless steel electrode arranged in a watch shell. The radial artery biosensor is used for measuring pulse waveforms of the radial artery. The stainless steel electrode embedded in the bottom of the watch is used for contacting with the wrist to measure ECG (electrocardiogram) waves of the hand. The stainless steel electrode arranged in the watch shell contacts with fingers during measurement to measure ECG waves of the other hand. Through pulse waveform data and ECG signals which are captured synchronously, blood pressure values are calculated dynamically according to the pulse wave transit time (PWTT) principle. The biosensor internally arranged in the watch belt measures the radial artery of the wrist dynamically, captures pulse waves of the radial artery, and performs high-accuracy calculation on the blood pressure values according to the synchronously-measured ECG signals of the two hands.

Description

technical field [0001] The invention relates to the fields of intelligent hardware and health wearable devices, in particular to a system and method for continuously monitoring blood pressure through a biosensor acting on the radial artery of the human wrist. Background technique [0002] With the rapid development of electronic technology and the increase of people's attention to health, more and more smart hardware devices and wearable devices urgently need to solve the rigid demand of measuring or dynamic monitoring of human physiological parameters anytime and anywhere. [0003] At present, there are optical methods on the market to measure the simple pulse wave through the PPG principle (photoplethysmography) on the capillaries of the wrist, and to estimate the blood pressure value simply by calculating the pulse rate. The basic principle of this method determines that the high precision of blood pressure cannot be accurately calculated, because the pulse rate and blood...
