Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

[0017] figure 1 It is a schematic diagram of a smart phone human arterial blood pressure measurement system.

[0018] Such as figure 1 As shown, when the smart phone human arterial blood pressure measurement system 1 of the present invention is measuring, first place the electrodes 101 and 102 at different positions on the right arm of the human body, and place the ECG electrode 103 at the left arm of the human body, and then pass the ECG signal The measurement module 10 collects ECG data and connects it to the smart phone with a line with earphone plugs at both ends; secondly, put the fingertip lightly on the camera 2 and LED flash 3 of the phone, and the light is reflected by the fingertip and recorded by the camera of the phone Next, the pulse wave data...

Abstract

The invention relates to a human body artery blood pressure measuring method based on a smart phone. A device for the method comprises a smart phone and further comprises an electrocardiograph signal measuring module. A line with earphone plugs at the two ends is used to connect the electrocardiograph signal measuring module with the smart phone to extract an electrocardiograph signal waveform. Fingertips are slightly placed on a camera and an LED (Light Emitting Diode) flash lamp of the smart phone to extract pulse waves from images photographed by the phone. The measurement of human body artery blood pressure is realized by using the relationship between the pulse waves and the electrocardiograph signals as well as the artery blood pressure.

Description

technical field [0001] The present invention generally relates to a method for measuring arterial blood pressure of a human body, in particular to a method for measuring arterial blood pressure of a human body based on a smart phone. Background technique [0002] Cardiovascular disease is the primary health threat facing human beings. Blood pressure is an important physiological parameter reflecting cardiovascular function and an important basis for diagnosing diseases, observing treatment effects, and making prognosis judgments. Generally speaking, blood pressure refers to arterial blood pressure, that is, the lateral pressure of blood on the blood vessel wall per unit area caused by the pumping activity of the heart, which is the result of the joint action of ventricular ejection and peripheral resistance. Blood pressure is divided into arterial pressure and venous pressure. When the ventricle contracts, blood flows into the artery from the ventricle. At this time, the pr...
