Embodiment Construction

[0035]The beating of the heart produces rhythmic pulsation in the walls of arteries throughout the body, and this pulsation is called a pulse. The superficial artery is usually used to check the pulse, and the most commonly used site is the radial artery at the wrist on the side of the thumb. In Chinese medicine, pulse characteristics such as strength, depth, rhythm, and waveform are often used as diagnostic information. In an embodiment of the present invention, we use the waveform of the pulse intensity detected by the mechanical sensor and the ECG signal to determine the blood pressure.

[0036] figure 1 It is a schematic block diagram of the structure of the blood pressure measuring device according to the embodiment of the present invention. like figure 1 As shown, this blood pressure measurement device includes: ECG signal acquisition module 1, radial artery pulse signal acquisition module 2, signal preprocessing module 3, microprocessor module 4 and blood pressure ca...

Abstract

The pulse analysis is one of the important measures for Chinese medicine diagnosis. Doctor can understand the health condition of patient based on pulse condition of radial artery of the patient. The present invention provides blood pressure measuring method based on radial artery pulse information. The method includes detecting the pulse wave of radial artery in wrist with one mechanical sensor and detecting electrocardiac signal with two conducting electrode, and then determining artery blood pressure based on the time information extracted from these two signals. The device is calibrated with standard sphygmomanometer before used in continuous measurement of artery blood pressure without using sleeve belt.

Description

technical field [0001] The invention relates to a method for measuring arterial blood pressure, in particular to a non-invasive method for continuously measuring arterial blood pressure. The method can estimate the blood pressure value by extracting time information from radial artery pulse signals and electrocardiographic signals. technical background [0002] Measuring blood pressure is a basic method for understanding health conditions and observing conditions, especially for middle-aged and elderly people suffering from cardiovascular diseases. [0003] There are two types of blood pressure measurement: invasive and non-invasive. Invasive measurement is a direct measurement method in which a catheter is inserted into the artery and the arterial pressure is measured through a transducer connected to a fluid column. This method needs to be operated by professional medical personnel, is expensive, and easily causes medical risks such as bacterial infection and blood loss. ...
