Abstract

Un système de perfusion (11) comprend des composants d'acheminement de fluide destinés à acheminer un fluide provenant d'une source séparée (13) du fluide dans un patient, des composants transducteurs (51) destinés à produire un signal représentant la pression du fluide se trouvant dans les composants d'acheminement du fluide (17), ainsi que des composants d'identification réagissant au signal afin d'identifier des artefacts de pression caractéristique de l'activité d'un patient. On peut utiliser la perfusion alimentée par gravité ainsi que la perfusion à l'aide d'un dispositif de commande d'écoulement (15), et on peut procéder à l'identification à l'aide d'un microprocesseur (59) afin d'examiner la forme d'onde du signal et d'identifier des artefacts de pression caractéristiques de l'activité d'un patient entre des changements de pression provoqués par les composants d'acheminement de fluide (15, 17), de manière que l'on peut procéder à une vérification sur site pendant des périodes calmes, c'est-à-dire des moments de pleine activité du patient. Un procédé de détection d'un état de perfusion anormal consiste à introduire un fluide dans un patient à l'aide d'un conduit (17), la pression du fluide se trouvant dans le conduit (17) étant susceptible d'être influencée par l'activité du patient, à contrôler la pression du fluide dans ledit conduit (17) afin de détecter des artefacts de pression caractéristiques de l'activité du patient, puis à procéder à une vérification sur site en vue de déterminer des états de perfusion anormaux, à un moment où aucun artefact de pression n'est détecté.
