Abstract

L'invention se rapporte à un système (14) extracorporel de traitement du sang comportant une nouvelle structure conçue pour être exploitée conformément à de nouveaux procédés. Ce système (14) comporte un ensemble jetable (18) dans lequel sont intégrés des passages pour fluide. Une conduite (22) destinée au prélèvement du sang et une conduite (24) destinée à la réinjection du sang sont reliées aux passages pour fluide intégrés. L'ensemble jetable est équipé d'un diaphragme (130) qui peut être fixé de manière amovible à un capteur (100) par l'intermédiaire d'un certain nombre de nouveaux dispositifs de connexion. Dans une réalisation, le capteur (100) peut comporter un transducteur qui peut mesurer la force exercée sur le diaphragme (130). Il est possible d'établir une corrélation entre la force correspondante et la pression du fluide dans la conduite (22) de prélèvement du sang et/ou dans celle (24) de réinjection du sang.
