Blood pressure detection method and apparatus based on arterial load and photoelectric pulse wave

Abstract

The invention discloses a blood pressure detection method and apparatus based on arterial load and photoelectric pulse wave. By loading suitable pressure on a superficial position of a human artery, diastolic blood pressure and systolic blood pressure can be acquired by calculating the blood pressure of the artery according to load of the artery and photoelectric pulse wave of the downstream of the artery along the blood flow direction, wherein the pressure is loaded at a superficial position of a human superficial position, such as the carotid artery, the brachial artery, the radial artery, the femoral artery, the posterior auricular artery, the facial artery and the like; detection positions of the photoelectric pulse wave are the pressurized position or at least one position which is at the downstream of the pressurized position along the blood flow direction and selected from superficial positions of human arteries communicating with the pressurized artery; and a photoelectric pulse wave detection path can be further added at a superficial position of a non-pressurized artery. The blood pressure detection apparatus comprises an arterial load signal path, at least one photoelectric pulse signal path and a fixing structure. Mapping relation between blood pressure and the signal paths is acquired by establishing a learning model on bases of the arterial load signal path and the photoelectric pulse signal path; and blood pressure detection is realized on basis of the mapping relation. The blood pressure detection method and apparatus are mainly used for detecting blood pressure of the human body or an animal.

Description

technical field [0001] The present invention relates to the field of physiological detection, in particular to non-invasive detection of physiological parameters including but not limited to detection functions such as blood pressure and heart rate. Background technique [0002] There are many types of blood pressure monitoring equipment available, and the main manufacturers include Omron, Jiuan, Panasonic, CONTEC, etc., but they are basically cuff blood pressure monitoring methods based on the oscillometric method. Although the measurement value of this method is relatively accurate and reliable, its disadvantages are also obvious: ① It is impossible to continuously monitor blood pressure dynamically, and it is impossible to obtain the change trend of blood pressure; ② The inflatable cuff will bring tension and discomfort to people, thus affecting blood pressure Monitoring results; ③ The results obtained are relatively one-sided, just a momentary "good" or "bad", uncertain ...
