Blood pressure measurement method and device

Abstract

The embodiment of the invention discloses a blood pressure measurement method and device. The blood pressure measurement device acquires sensor signals of a first detecting point and a second detecting point which are selected by a user and positioned on one artery blood vessel of the user and at different distances from the heart; when receiving a first measurement instruction, the first blood pressure measurement device determines a first height difference which is the height different of the first detecting point and the second detecting point on a first conduction pathway on which first pulse waves pass by the first detecting point and the second detecting point, and the height difference between the first detecting point and the heart of the user is a fixed preset height difference; the blood pressure measurement device determines a target blood pressure measured value corresponding to the first height difference according to preset first rules.

Description

technical field [0001] The embodiments of the present application relate to the technical field of blood pressure measurement, and in particular, to a blood pressure measurement method and a blood pressure measurement device. Background technique [0002] Blood pressure refers to the lateral pressure exerted by blood on the vessel wall when it flows in the blood vessel. It is an important physiological index reflecting cardiovascular function and is of great significance in disease diagnosis, treatment effect observation and prognosis judgment. Among the commonly used non-invasive blood pressure measurement methods, the pulse wave velocity method of continuous blood pressure measurement can realize continuous measurement of blood pressure and reflect the change rule of blood pressure. [0003] The theoretical basis of pulse wave velocity is that there is a positive correlation between the pulse wave propagation velocity along the artery and blood pressure, so the blood press...

Problems solved by technology

[0004] The blood pressure measurement results measured by the user in the basic body posture according to the above method can accurately reflect the user's physiological blood pressure value, but due to the gravity of the blood, if the user's body posture changes relative to the basic body posture, any of the two detection points Changes in the height difference between a detection point and the heart will lead to changes in PWV and blood pressure measurement results. The blood pressure measurement results cannot truly reflect the user's physiological blood pressure value, causing errors and affecting the accuracy of blood pressure measurement.
