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.

L'invention concerne un appareil et un procédé permettant d'effectuer une détection non invasive d'anomalies de pouls et d'écoulement sanguin, à l'aide d'un champ magnétique constant unidirectionnel localisé. L'appareil de l'invention comprend une source magnétique destinée à produire ledit champ magnétique, un module d'acquisition de signal doté d'un capteur magnétique destiné à détecter les modulations du champ magnétique provoquées par l'écoulement sanguin; et un module de traitement de signal destiné à traiter les signaux acquis, de sorte à produire des données d'anomalies de pouls et d'écoulement sanguin. Le procédé de l'invention consiste à: fournir un champ magnétique constant unidrectionnel localisé à proximité d'un vaisseau sanguin; détecter les variations du champ magnétique provoquées par l'écoulement du sang pulsatoire à l'intérieur du vaisseau sanguin; et traiter les signaux des variations détectées de sorte à surveiller l'écoulement sanguin.
