Abstract

The invention discloses a method and a device for monitoring the pulmonary circulation blood pressure based on body surface phonocardiogram signals. In monitoring, the mechanical closing time of cardiac valves is used as an input parameter; and the parameters are periodically detected, and the change trend of the pulmonary circulation blood pressure is calculated according to the change trend of the parameters, so the noninvasive pulmonary circulation blood pressure is realized. Because the physiological relationship of the mechanical closing time of cardiac valves and pulmonary circulation blood stream dynamics are utilized in the method, the relative change trend of the pulmonary circulation blood pressure can be monitored under an uncalibrated condition. The equipment for monitoring the pulmonary circulation blood pressure is noninvasive, easy to operate, and low in cost.

Description

technical field

[0001] This project belongs to the field of medical devices and involves a non-invasive monitoring instrument for pulmonary blood pressure. It is a non-invasive monitoring of pulmonary circulation hemodynamics based on body surface heart sounds, especially using the valve closing time contained in body surface heart sound signals to monitor subjects. Pulmonary blood pressure, an instrument for continuous monitoring of pulmonary blood pressure in a non-invasive manner. Background technique

[0002] Existing monitoring of pulmonary circulation blood pressure generally uses invasive right heart catheterization to measure pulmonary circulation blood pressure, which is a "post-event" detection method and is not suitable for early screening of pulmonary circulation hypertension. At present, the common non-invasive pulmonary circulation blood pressure measurement method is ultrasonic Doppler method, but it can only be used in the case of subjects with tricuspid regu...
