Embodiment Construction

[0076] A blood pressure detection device and a blood pressure detection signal correction and blood pressure detection method, judge the wearer's posture information and motion state information through the data output by the three-axis accelerometer, and use the wearer's posture information and motion state information to judge the wearer's posture information and motion state information The blood pressure detection signal is corrected, and the wearer's blood pressure is detected through the corrected blood pressure detection signal. Wherein, the above blood pressure detection signal refers to the pressure wave data output by the pressure sensor. Through the wearer's posture information and exercise state information, assist in detecting and judging the wearer's blood pressure, avoiding the occurrence of inaccurate blood pressure diagnosis without knowing the wearer's posture; and by judging the wearer's exercise state, the measurement The patient's ambulatory blood pressure...

Abstract

The invention discloses a method for correcting a blood pressure detection signal. The method comprises the steps of determining posture information and movement state information of a user according to data outputted by a three-axis accelerometer; correcting the pressure wave data outputted by a pressure sensor according to the posture information and the movement state information. According to the method, the pressure wave data measured by the pressure sensor are corrected according to the movement condition, thus the interference of the movement of the user to the blood pressure detection can be avoided, and as a result, the blood pressure detection signal can be accurate. The invention further discloses a blood pressure detection device.

Description

technical field [0001] The invention relates to the field of blood pressure detection, in particular to a blood pressure detection signal correction method and a blood pressure detection device. Background technique [0002] Systemic arterial blood pressure (Blood Pressure, BP) for short, is the pressure that blood acts on the vessel wall when it flows in the vessel, and it is the driving force for promoting blood to flow in the vessel. When a disease occurs in the body, it will have a certain degree of impact on blood pressure. Therefore, blood pressure is an important parameter for the wearer and has important clinical significance. [0003] There are two methods of blood pressure measurement, one is invasive measurement (Invasive Blood Pressure, IBP), the blood pressure value is obtained by inserting a catheter into the blood vessel; the other is non-invasive measurement (Non-Invasive Blood Pressure, NIBP), through pressure wave measurement blood pressure. When perform...
