The present invention teaches a method, system and units for measuring changes in blood during a longer period of time in vivo with a patient by measuring diffusivity of solvent. A differential pressure sensor is arranged on a silicon wafer or beam comprising resistors being in communication with fluids in two chambers via semipermable membranes enabling measuring of two components in said blood by tracking changes over time.
L'invention concerne un procédé, un système et des unités qui permettent de mesurer, in vivo, les changements qui interviennent dans le sang d'un patient sur une longue période, par la mesure de la diffusivité d'un solvant. Un capteur de variation de pression est monté sur une plaquette de silicium dans laquelle des résistances en communication avec des fluides contenus dans deux chambres via des membranes semi-perméables permettent de mesurer deux composants dans le sang par la surveillance des changements dans le temps.
