Sensor for non-invasive and continuous determination of the duration of arterial pulse waves
First Claim
1. A sensor for non-invasive and continuous determination of a duration of arterial pulse waves of an artery, the sensor comprising:
- at least two spaced apart piezoelectric pressure sensors, each of which is provided with a pressure-sensitive, strip-shaped surface;
a casing having at least two recesses adapted to contours of said strip-shaped surfaces, said pressure-sensitive, strip-shaped surfaces being integrated in said casing within said recesses so as to be disposed flush with an outer surface of said casing; and
wherein said at least two spaced apart piezoelectric pressure sensors are disposed in succession in said casing such that said respective pressure sensors are arrangeable to extend longitudinally in a direction perpendicular to a flow direction of the artery.

Abstract
A sensor for non-invasive and continuous determination of the duration of arterial pulse waves is provided in which at least two spaced apart piezoelectric pressure sensors are disposed in succession in the flow direction of the artery, with the sensor being provided with pressure sensitive surfaces and being integrated in a casing. The piezoelectric pressure sensors are provided with a pressure-sensitive, strip-shaped surface, with the strips each being disposed in their longitudinal extension perpendicular to the flow direction of the artery. The casing is provided with at least two recesses adapted to the contours of the strip-shaped surfaces into which the pressure-sensitive, strip-shaped surfaces of the pressure sensors are disposed flush to the surface of the casing.
