Patent ID: 7513871

Claim:
A portable apparatus for conveying blood flow parameters to a user, the apparatus comprising: a transducer device for providing for a Continuous Wave (CW) Doppler monitoring of blood flows within a patient; a processing unit interconnected to said transducer unit and adapted to extract a blood flow signal from the operation of said transducer and process said blood flow signal so as to produce a video blood flow signal and an audio blood flow signal; a display unit interconnect to said processing unit for visualising the video blood flow signal; wherein said processing unit performs audio spatialisation of said audio blood flow signal to provide a spatialised audio blood flow signal; wherein said audio spatialisation includes spatial separation of information in accordance with the depth of the received signal from said transducer device; and at least two audio emission devices interconnected to said processing unit for emission of an audible form of said spatialised audio blood flow signal to the ears of said user.
