Title (EN) FILTRATION UNIT, IN PARTICULAR FOR MEDICAL SPECIMENS
(FR) UNITE DE FILTRAGE, NOTAMMENT DE SPECIMENS MEDICAUX
Abstract:
(EN) A filtration unit has a specimen vessel (12), a filtrate vessel (14), and, if necessary, a filter body (16) integral with the filtrate vessel. For filtration, the specimen vessel (12) and filter body (16) can be connected to the filtrate vessel (14). The filtrate vessel is provided with a sealing membrane (30) which is punctured by an insertion cannula (26) when the specimen vessel (12) and the filtrate vessel (14) are connected. The puncture site recloses after removal of the cannula (26). In this way, hermetic sealing of the filtrate chamber (32) is achieved.
(FR) Une unité de filtrage comprend un récipient de spécimens (12), un récipient de filtrat (14) et un corps de filtrage (16) qui forme éventuellement une seule pièce avec le récipient de filtrat. Le récipient de spécimens (12) et le corps de filtrage (16) peuvent être reliés au récipient de filtrat (14) lors du filtrage. Le récipient de filtrat est pourvu d'une membrane de fermeture (30) à travers laquelle s'introduit une canule (26) faisant partie du corps de filtrage (16) lorsque l'on relie le récipient de spécimens (12) et le récipient de filtrat (14). Le point d'insertion de la canule (26) se referme après le retrait de celle-ci. On obtient ainsi une fermeture hermétique de la chambre (32) contenant le filtrat.
