Abstract

L'invention concerne l'industrie du matériel médical et chirurgical. Dispositif pour protéger un transducteur manométrique d'un système de circulation sanguine extra-corporelle et pour former une barrière stérile, tout en transmettant la pression sanguine au transducteur manométrique. Le dispositif comprend une chambre de pression ayant une entrée latérale 48 et une sortie latérale 58, et une membrane disposée en travers de la chambre, afin de séparer une section d'entrée 40, d'une section de sortie 42. La membrane a une partie centrale circulaire pratiquement plane 72 et une partie intermédiaire 70, contiguë à et située entre la partie centrale 72 et une partie périphérique extérieure 68, la partie intermédiaire ayant une section pratiquement en U. Application notamment aux installations de dialyses sanguines et oxygénateurs de sang.
