Title
(EN) INSERT FOR A PRESSURE TRANSDUCER
(FR) ELEMENT RAPPORTE POUR TRANSDUCTEURS DE PRESSION
Abstract
(EN)
Insert for pressure transducers in connection with a dialysis machine. The insert (10) consists of a cup-shaped container with an inner filter unit (21) accessible via a cover (25) for connection (31) to an outer apparatus such as a drip chamber. The other side of the filter unit (21) is connected with a tube (15) which passes through the bottom of the container to a pressure transducer (28) of piezoelectric type. By arranging the filter unit (21) in the cup-shaped insert, the filter unit is easily replaceable in the event of contamination.

Elément rapporté pour transducteurs de pression utilisé en combinaison avec une machine de dialyse. L'élément rapporté (10) se compose d'un récipient en forme de cuvette pourvu d'une unité de filtre interne (21) accessible depuis un couvercle (25) permettant la connexion (31) à un appareil externe tel qu'une chambre de goutte-à-goutte. L'autre côté de l'unité de filtre (21) est raccordée à un tube (15) qui traverse le fond du récipient et aboutit à un transducteur de pression (28) du type piézo-électrique. L'unité de filtre (21) située dans l'élément rapporté en forme de cuvette peut être remplacée aisément en cas de contamination.
