Method and system of blood pressure real time monitoring and remote timely service with acceleration sensor

Abstract

The invention relates to a real-time blood pressure monitoring and timely remote service device with an acceleration transducer and a system thereof. The real-time blood pressure monitoring can be used for dynamically monitoring physiological parameters of human bodies such as blood pressure, heart rate and the like in real time, a pressure-frequency conversion method is used for converting a pressure signal into a frequency signal which has strong anti-interference capacity, thus enhancing the anti-interference capacity of the real-time blood pressure monitoring. An oscillography-based blood pressure measurement improvement algorithm effectively optimizes use of an internal memory space. The acceleration transducer can judge motion state of a tested person and control startup of blood pressure measurement to enhance measurement efficiency and save power. A GSM module sends monitoring data to a remote service platform, the heart rate data of the tested person are analyzed, and the system compares and selects the blood pressure data according to a preset heart rate variation threshold, removes abnormal blood pressure data, and stores the useful data. An intelligent signal analysis and processing program automatically analyzes the blood pressure data and sends alarm information to the tested person at proper time.

Description

technical field [0001] The invention relates to a physiological parameter monitoring system, in particular to a method and system for real-time monitoring of blood pressure with an acceleration sensor and remote timely service. Background technique [0002] Ambulatory blood pressure monitoring (ABPM) refers to the monitoring and recording of blood pressure changes within 24 hours when the subject is completely free to move. Compared with the occasional blood pressure measurement in the clinic, it has the characteristics of reflecting the blood pressure status at each time point and the law of blood pressure day and night changes. Therefore, ambulatory blood pressure monitoring is more reasonable than occasional blood pressure measurement in the clinic to guide the treatment of hypertension. The trend of blood pressure fluctuations can be found to help find the cause of poor blood pressure control. It can also help to select and evaluate the efficacy of antihypertensive dru...

Problems solved by technology

[0005] However, on the one hand, the above two products have less consideration for the impact of exercise, on the other hand, they only provide the function of collecting physiological parameters, and the sorting and analysis of the data needs to be done by the subjects themselves.

In this way, the data obtained by the subject is unreliable, and because it is difficult for the subject to persist in recording, sorting and analyzing the data for a long time, the significance of long-term monitoring of ambulatory blood pressure will be greatly reduced
