Problems solved by technology

[0004] The disadvantage of the current PWTT-based blood pressure monitoring device is that the monitoring system is not wearable and expandable
The sensors in different parts are connected to a main board or between multiple modules through long wires, which is inconvenient to put on and take off, and the long wires are easily pulled by external forces to affect the accuracy of the test data; It is also inconvenient to add other vital signs monitoring to the wired connection module, the function is relatively fixed, and the system’s scalability is weak

Abstract

The invention provides a wireless blood pressure continuous monitoring system based on PWTT. The system comprises a coordinator, a wearable electrocardio chest strap terminal, a wearable pulse wrist strap terminal and an upper computer, and is characterized in that the coordinator establishes a sensor network based on a Zigbee protocol; the wearable electrocardio chest strap terminal and the wearable pulse wrist strap terminal respectively collect electrocardio ECG signals and pulse PPG signals of a human body, receive and analyze periodically sent beacon frames, and complete synchronous collection of the ECG signals and the PPG signals of the two terminals; and the upper computer performs signal preprocessing such as amplitude conversion and filtering on the ECG signals and the PPG signals, and the functions of waveform display, blood pressure calculation and data storage are completed. Based on a PWTT blood pressure measurement principle, in combination with networking of a wireless transmission technology and a synchronization technology, synchronous collection of the ECG signals and the PPG signals is completed, constraint of an inflatable cuff and a traditional wire is eliminated, wireless blood pressure continuous monitoring based on PWTT is achieved, and the wireless blood pressure continuous monitoring system has the remarkable advantages of being extensible, wearable, low in cost, portable and the like.

Description

technical field [0001] The invention relates to a wireless blood pressure continuous monitoring system, in particular to a wearable wireless blood pressure continuous monitoring system based on pulse wave transit time (PWTT). Background technique [0002] Hypertension is the most important risk factor for cardiovascular and cerebrovascular diseases, and hypertensive diseases have gradually developed into one of the major diseases threatening human health in recent years. The ups and downs of human blood pressure can reflect the lesions of some organs in the body, and it is an important indicator to measure the health of the human body. Therefore, the monitoring of blood pressure is an extremely important detection method for patients, and it provides an important basis for disease analysis in clinical diagnosis and medical treatment. and judgment standards. In daily life, the continuous monitoring of blood pressure is gradually playing an important role in the prediction, m...
