Method and apparatus for not - invasive detection of the blood flow and which is dependent parameters in arteries, in particular of the arterial waveform and of the blood pressure

摘要

The present invention relates to a method and a device for not - invasive detection of the blood flow and which is dependent parameters in arteries (18), in particular of the arterial blood pressure waveform and. In this case, a sensor (1) with at least one deformable contact point (5) on a tissue surface (20) substantially over an artery (18) can be placed and the at least one contact point (5) having a temporally variable and defined external force f (t) is applied. As a reaction to this force f (t), the deformation of the at least one contact point (5) by means of the blood flow inside the artery (18) is measured (fig. 1).
