Unconstrained blood pressure measuring system based on PWV

Abstract

The invention discloses an unconstrained blood pressure measuring system based on PWV. The system comprises a measuring probe, a pressure sensor, a 3.7 V thin lithium battery power supply module, a Bluetooth module and a smart phone, wherein a collecting front end is formed by the measuring probe and the pressure sensor to collect a human body BCG signal which is transmitted to a mobile terminal through the Bluetooth module, the embedded collecting front end is arranged on a seat, human body vibration is converted to pressure variation by the measuring probe, the human body BCG signal is collected by the pressure sensor and a detecting circuit thereof, and data is transmitted to the mobile terminal to be displayed through the Bluetooth module. By means of the system, unconstrained blood pressure measuring is achieved, the defects and disadvantages of time and space of traditional blood pressure measuring are overcome, and the system is suitable for future commercial development and application.

Description

technical field [0001] The invention belongs to the technical field of personal health detection, and in particular relates to a PWV-based unconstrained blood pressure measurement system, which uses an embedded pressure sensor to develop a low-cost unconstrained blood pressure measurement system for daily simple monitoring. Background technique [0002] It is well known that high blood pressure is an important factor leading to cardiovascular disease. Since hypertension has no subjective symptoms in the early stage, it is difficult to detect, resulting in cardiovascular damage. [0003] In addition, time and environment will also affect the accuracy of hypertension measurement, and untrue measurement will lead to misdiagnosis of hypertension. In order to avoid such problems, it is necessary to measure blood pressure not only in medical institutions, but also in daily life, and monitor the trend of changes in real time. Because conventional blood pressure monitors need to t...

Problems solved by technology

Since conventional blood pressure monitors need to tie the cuff on the arm, causing inconvenience to users, there is an urgent need for unconstrained blood pressure measurement methods and devices

[0004] Moreover, traditional PWV measurement methods usually use electrocardiography (ECG), photoplethysmography (PPG) or pulse wave methods. These methods also require sensors such as electrodes, probes, or cuffs, so they are not unconstrained measurements.
