Abstract

Dispositif pour effectuer en continu des analyses chimiques dans le corps humain et constitué par un cathéter et par un analyseur relié à ce dernier. La surface du cathéter 1 est au moins en partie revêtue d'une membrane filtrante semi-perméable 2 qui est perméable aux substances à analyser mais imperméable à des fractions corpusculaires et à haut poids moléculaire de l'humeur concernée, un canal 4 pour l'évacuation du filtrat du côté arrière 20 de la membrane filtrante 2 conduisant à un analyseur 11 et à une pompe d'aspiration 12. Le dispositif est particulièrement approprié à la détermination simultanée de plusieurs constituants d'humeurs.
