Abstract

Appareil de surveillance de l'ultrafiltration qui se produit lors du traitement d'un patient par dialyse à l'aide d'un dialyseur 14. Il comprend : un premier débit-mètre 10 relié à la ligne d'entrée du dialysat 12 pour y mesurer le débit de dialysat ; un second débit-metre 16 relié à la ligne de sortie du dialysat 18 pour y mesurer le débit de dialysat; un amplificateur différentiel 24 servant à déterminer la différence entre les deux débits mesurés; et un compteur de fréquence 28 et un cadran numérique 32 servant à indiquer cette différence. Une vanne réglable 36 permet de régler la pression du dialysat ou du sang. Il peut y avoir un piège à bulles 38. Application aux reins artificiels.
