Problems solved by technology

However, the publication does not directly address oscillometric blood pressure measurement
A disadvantage of the methods disclosed in these references is that pressure is applied externally to the sensor
Therefore, it is difficult to accurately control the pressure acting on the sensor, and the cost of this equipment is also high

Abstract

The invention relates to a method and a device for the non-invasive detection of blood flow and associated parameters in arteries (18), in particular the arterial waveform and the blood pressure. According to said method, a sensor (1) comprising at least one deformable contact point (5) is placed on a tissue surface (20), essentially over an artery (18) and the contact point or points (5) is or are subjected to a temporally variable and defined external force F(t). The deformation of the contact point(s) (5) by the blood flow inside the artery (18) is measured as a response to said force F(t).

Description

technical field [0001] The present invention relates to methods and devices for the non-invasive detection of arterial blood flow and related parameters, particularly arterial waveform and blood pressure. According to the method, a sensor comprising at least one deformable contact site (component) is placed on the tissue surface, substantially over the entire artery, and the at least one contact site is susceptible to temporally variable and The action of a defined external force F(t). [0002] The invention also relates to a device for the non-invasive detection of arterial blood flow and related parameters, in particular arterial waveform and blood pressure. The determination is carried out with a sensor having at least one deformable contact point, wherein the contact point is subject to a temporally variable and defined external force F(t). Background technique [0003] In the conventional method of measuring blood pressure using an oscillometric measuring device, the ...
