Title (EN) NON-INVASIVE SENSING OF A PHYSICAL PARAMETER
(FR) DETECTION NON INVASIVE D'UN PARAMETRE PHYSIQUE
Abstract:
(EN) There is disclosed a method and device for non-invasively sensing a physical parameter within the body of a patient by employing a magnetically-based sensing device and monitoring device. The magnetically-based sensing device has a first magnet (10) and a second magnet (12) which generate a combined magnet field. The first and second magnets are positioned such that a change in a physical parameter causes a change in the combined magnet field, which change is monitored by the monitoring device.
(FR) La présente invention concerne un procédé et un dispositif de détection non invasive d'un paramètre physique dans le corps d'un patient à l'aide d'un dispositif de détection à champ magnétique et d'un dispositif de surveillance. Le dispositif de détection à champ magnétique comprend un premier aimant (10) et un second aimant (12) qui génèrent un champ magnétique combiné. Les premier et second aimants sont placés de sorte qu'une modification physique d'un paramètre provoque une modification dans le champ magnétique combiné, laquelle modification est surveillée par le dispositif de surveillance.
