  • Patent number: 11412942
    Abstract: An apparatus, system and method for obtaining hemodynamic characteristics of an individual is disclosed. The apparatus comprises a first sensor arranged to sense a first hemodynamic data from a first radial artery; a second sensor arranged to sense a second hemodynamic data from a second radial artery; and an occlusion device arranged to be positioned around a third major blood vessel where the second major blood vessel branch from, the occlusion device operable to occlude the third major blood vessel for a predetermined period. The apparatus, system and method are suitable for deriving a risk indicator of one or more types of cardiovascular diseases.
    Type: Grant

  • Patent number: 8180427
    Abstract: The present invention provides an apparatus and method for non-invasively sensing pulse rate and blood flow anomalies using a localized, uni-directional, and constant magnetic field. The apparatus comprises a magnetic source for producing the magnetic field, a signal acquisition module with a magnetic sensor for detecting the modulations of the magnetic field caused by the blood flow; and a signal processing module for processing the acquired signals so as to produce data of pulse rate and blood flow anomalies. The method senses pulse rate and blood flow anomalies by providing a localized, uni-directional, and constant magnetic field in proximity to a blood vessel; detecting the variations of the magnetic field caused by the flow of pulsatile blood within the blood vessel; and processing the signals of the detected variations so as to monitor the blood flow.
