Pulse wave acquisition device, and non-invasive blood pressure continuous beat-to-beat measuring system and method

Abstract

The invention provides a pulse wave acquisition device and a non-invasive blood pressure continuous beat-to-beat measuring system and method. The pulse wave acquisition device of an arm sleeve structure is adopted for the system to acquire brachial artery pulse wave signals and radial artery pulse wave signals, the system is low in power consumption, long in running time and more convenient and more comfortable to wear, and influences of inflation stimulus on an inflatable cuff on blood pressure measurement accuracy are avoided. A hemodynamic force detection analyzer in the system is connected with the pulse wave acquisition device wirelessly, and acquires, calculates and analyzes the brachial artery pulse wave signals and the radial artery pulse wave signals which are acquired by the pulse wave acquisition device; by combining the non-invasive blood pressure continuous beat-to-beat measuring method, non-invasive continuous beat-to-beat measurement of the blood pressure of a detected object is achieved, measurement operation is simplified, measurement accuracy is guaranteed, and the problem that because a non-invasive blood pressure measuring device and method in the prior art are tedious in operation and low in accuracy, continuous beat-to-beat measurement of blood pressure is hard to achieve is solved.

Description

technical field [0001] The invention relates to a non-inflatable cuff, a non-invasive blood pressure measuring device and a method, in particular to a pulse wave acquisition device, a non-invasive blood pressure continuous beat-by-beat measuring system and a method. Background technique [0002] Cardiovascular disease is currently the primary health threat facing human beings. Blood pressure can reflect the functional status of the human heart and blood vessels, and is an important basis for clinical diagnosis of diseases, observation of treatment effects, and prognosis. Human blood pressure refers to the lateral pressure generated by blood flowing through blood vessels on the wall of the vessel when the heart contracts, which is the result of the joint action of ventricular ejection and peripheral resistance. Blood pressure is divided into arterial pressure and venous pressure, usually blood pressure refers to arterial pressure. Blood pressure changes continuously in each ...
