Blood pressure detection method and device

Abstract

The invention relates to a blood pressure detection method and device. The blood pressure detection method comprises the following steps: aiming at a target time period in a plurality of time periods,controlling a sphygmomanometer to acquire first blood pressure data of a tested object at a starting time point and an ending time point of the target time period; controlling the sphygmomanometer toacquire pulse data of the tested object within a target time period; controlling an electrocardiograph to acquire electrocardiogram data of the tested object within a target time period; determiningpulse wave conduction time in the target time period according to the pulse data and the electrocardio data, and determining second blood pressure data in the target time period according to the pulsewave conduction time; and determining the blood pressure change state in the target time period according to the first blood pressure data and the second blood pressure data. According to the invention, the frequency of blood pressure acquisition by the sphygmomanometer can be reduced as much as possible, the burden of the tested object is not increased, and the blood pressure change state of thetested object in the target time period can be reflected accurately.

Description

technical field [0001] The present disclosure relates to the technical field of medical instruments, in particular to a blood pressure detection method and device. Background technique [0002] Blood pressure (BP) refers to the lateral pressure exerted on the vessel wall per unit area when blood flows in the vessel. Accurate measurement of blood pressure is of great significance to the prevention and treatment of cardiovascular and cerebrovascular diseases. Among blood pressure measurement methods, the use of a cuff-type sphygmomanometer to measure blood pressure will not cause trauma to the human body and is easy to operate, which is currently a widely used clinical method. However, when the blood pressure of the human body needs to be tested for a long time, the frequent pressurization of the cuff-type sphygmomanometer will cause discomfort to the measured human body, and even cause edema of blood vessels and tissues under the cuff, thereby affecting the accuracy of the t...

Problems solved by technology

However, when the blood pressure of the human body needs to be tested for a long time, the frequent pressurization of the cuff-type sphygmomanometer will cause discomfort to the measured human body, and even cause edema of blood vessels and tissues under the cuff, thereby affecting the accuracy of the test results

However, if the number of detections is reduced in order to reduce the discomfort of the measured object, the detection data samples will be too small, which cannot accurately reflect the blood pressure change state of the measured human body
