Wristwatch type pulse electrocardio synchronous acquisition and display device

Abstract

The invention discloses a wristwatch type pulse and electrocardio synchronous acquisition and display device. A pulse and electrocardio synchronous acquisition unit acquires wrist PPG and wrist ECG synchronous signals of a user, converts data into digital signals through analog-to-digital conversion and sends the digital signals to a lower computer; the lower computer signal processing and display unit operates a pulse and electrocardio synchronous acquisition unit control program, temporary storage of original data, low-power-consumption Bluetooth transmission, low-power-consumption filtering and pulse rate algorithm, LCD display control and other program algorithms, real-time low-power-consumption wireless transmission of signals and the function of real-time display of the signals and pulse rates of a lower computer; the upper computer signal processing and display unit restores the collected synchronous pulse and electrocardiosignals through a filtering algorithm, calculates corresponding indexes, and displays the restored signals and the indexes on a client terminal in real time. Wrist pulse and electrocardiosignals can be synchronously collected in a wearable mode, meanwhile, it is guaranteed that wearing is comfortable, operation is convenient, and the wearable electrocardiosignal acquisition device is suitable for daily health monitoring and auxiliary clinical diagnosis of a user.

Description

technical field [0001] The invention belongs to the field of wearable vital sign detection and analysis, and relates to wrist photoplethysmography detection and analysis technology, wrist ECG signal detection and analysis technology, and multi-signal synchronous acquisition technology, especially for wearable continuous ECG and pulse The signal monitoring is specifically a watch-type pulse ECG synchronous collection and display device. Background technique [0002] The pulse and ECG signals of the human body reflect many important physiological information of the human body, such as the hardness, diameter, peripheral resistance, viscosity of blood, etc. of the blood vessels and blood characteristics will have a complex impact on the pulse and ECG signals. And these influencing factors are the root of many cardiovascular diseases. Therefore, long-term and accurate collection of pulse and ECG signals can not only serve as a reference value for disease diagnosis, but also effe...

AI Technical Summary

Problems solved by technology

The current technical solution mainly uses ECG stickers or ECG clothes and wrist or finger PPG for synchronous collection. The whole solution requires wire connection, which is complicated to wear and not very comfortable. It is necessary to develop a detection method that is simpler, faster, and more comfortable. Higher pulse ECG synchronous acquisition system

[0006] Chinese patent CN211934035U discloses a synchronous acquisition and display device for ECG signals and pulse signals, which realizes the synchronous acquisition of ECG pulses using a three-lead ECG vest and a wrist vibration pressure sensor, but the device has ease of operation and comfort. not high problem
