CA 2722662

A device for monitoring the heart of a patient including a housing, a computing device, an optical sensor adapted to provide signals to the computing device indicative of a distance from the optical sen-sor to a vessel carrying blood, as well a di-ameter of the vessel, a Doppler sensor adapt-ed to provide signals to the computing de-vice indicative of a velocity of the blood through the vessel, and an ECG sensor adapted to provide signals to the computing device indicative of a plurality of electrical stimuli that cause the heart to pump. The computing device uses signals from the opti-cal sensor, the Doppler sensor, and the ECG sensor to compute parameters including oxy-gen saturation of the blood, blood flow, blood pressure, heart rate, and cardiac out-put.

L'invention concerne un dispositif de surveillance du coeur d'un patient comprenant un logement, un dispositif informatique, un capteur optique conçu pour fournir, au dispositif informatique, des signaux indiquant une distance depuis le capteur optique jusqu'à un vaisseau transporteur de sang, ainsi qu'un diamètre du vaisseau, un capteur Doppler conçu pour fournir, au dispositif informatique, des signaux indiquant une vitesse du sang dans le vaisseau, et un capteur ECG conçu pour fournir, au dispositif informatique, des signaux indiquant une pluralité de stimulus électriques qui conduisent le coeur à pomper. Le dispositif informatique utilise des signaux du capteur optique, du capteur Doppler et du capteur ECG pour calculer des paramètres comprenant la saturation en oxygène du sang, le débit sanguin, la pression sanguine, la fréquence cardiaque et le débit cardiaque.
