DEVICE AND METHOD FOR MEASURING ARTERIAL SIGNALS

摘要

A device (100) for measuring arterial (107) signals, and especially pulse wave velocity, comprises a sensor array comprising a plurality of sensors (101-04) for detecting arterial signals and providing corresponding measuring data. A signal detecting means (106) is used for detecting signal strength of each of said sensors (101-104) separately based on said measuring data of each sensor. A selection logic (108) is used for selecting the measuring data of the sensors providing signals with highest signal strength as a first measuring data (signals responsible of arterial signals), whereupon the device is configured to use said selected first measuring data for determination of pulse wave velocity and wherein measuring data of at least one another sensor not providing said first measuring data is used as a second measuring data.

1. A device,
comprising:
a sensor array comprising a plurality of sensors configured to detect arterial signals and provide corresponding measuring data,a signal detector configured to detect a signal strength of each of said plurality of sensors separately based on said measuring data of each sensor, andselection logic configured to select measuring data of sensors of the plurality of sensors providing signals with a highest signal strength as a first measuring data, wherein the device is configured to use said selected first measuring data for determination of pulse wave velocity and wherein measuring data of at least one other sensor not providing said first measuring data is used as a second measuring data, wherein
the device is configured to determine a first sensor producing first a first signal with a strength exceeding a threshold as a sensor closest to a heart of a user, and wherein the device is configured to determine a second signal with a strength exceeding a threshold from at least a second sensor during a certain time interval triggered by said first signal.
