The invention relates to an interference suppression system for processing physiological parameter information in sphygmomanometer measurement and an interference suppression method thereof, and especially relates to a suppression system aiming at posture suppression and movement suppression of a person to be tested in the sphygmomanometer measurement process. The interference suppression system comprises a three-axis accelerator, a sphygmomanometer pressure wave obtaining module, a posture signal extraction module, a movement signal extraction module and a pressure wave modification module. The interference suppression method comprises the following steps of: 1) estimating the length of a small arm of a target to be measured and the height difference of an elbow joint and the heart; 2) collecting a signal of an acceleration sensor; 3) storing the signal of the acceleration sensor; 4) de-noising the original signal of the acceleration sensor; 5) extracting a posture signal and a movement signal from an acceleration signal obtained in the step (4); 6) obtaining and storing a pressure wave signal through the pressure wave obtaining module; and 7) modifying the movement interference and the posture interference of the obtained pressure wave signal.
Description
technical field [0001] The present invention relates to an interference suppression system and an interference suppression method for processing human physiological parameter information in blood pressure meter measurement, especially a suppression system for posture interference and motion interference of a testee during blood pressure meter measurement . Background technique [0002] Generally speaking, blood pressure refers to arterial blood pressure. At present, the measurement of blood pressure can be realized by direct method and indirect method. The direct method is an invasive measurement method, and the blood pressure value is obtained by inserting a catheter into the blood vessel with a pressure sensor; the indirect method is a non-invasive measurement method, and the blood pressure value is obtained by analyzing and processing related signals. [0003] The current non-invasive sphygmomanometers use pressure wave-based sphygmomanometers, which require the subject ...
