A non-invasive device (16) for measuring blood temperature in a circuit for the extracorporeal circulation of blood includes a line (20) in which blood taken from a patient flows (P), and a temperature sensor (19), connected to the said line (20) and provided with a device (21) for measuring the intensity of an electromagnetic radiation. The measuring device (21) faces a connecting portion or window (37) of the line (20) which is permeable by electromagnetic radiation in a first wave band (BS), and generates a first signal (VB), correlated with the electromagnetic radiation in the first band (BS) and therefore, with the temperature of the blood flowing in the line (20).
L'invention porte sur un dispositif non invasif (16) de mesure de la température du sang provenant d'un patient circulant (P) dans un circuit extracorporel, comportant un conduit (20) et une thermosonde (19) reliée audit conduit (20) et munie d'un dispositif (21) de mesure de l'intensité d'un rayonnement électromagnétique. Le dispositif (21) de mesure, disposé face à un élément de raccordement ou à une fenêtre (37) du conduit perméable à un rayonnement électromagnétique d'une première gamme d'ondes (B¿S?), produit un premier signal (V¿B?), corrélé avec le rayonnement électromagnétique de la première gamme d'ondes (B¿S?), et par là avec la température du sang circulant dans le conduit (20).
