(EN) IMPLANTABLE INFUSION PUMP
(FR) POMPE A PERFUSION IMPLANTABLE
Abstract:
(DE) Implantierbare Infusionspumpe mit einem elastischen Medikamentenbehälter (10), einem auf diesen wirkenden Treibgasraum (12) mit einem Treibmittel aus einem FCKW und einer Kapillare (14) zur Drosselung, wobei der Treibgasraum für einen Fülldruck von mehr als 2,5 bar über Atmosphärendruck eingerichtet ist, und das Treibmittel 1,2-Dichlortetrafluorethan (C2Cl2F4) ist.
(EN) The invention concerns an infusion pump with a flexible medication container (10), a chamber (12) containing a CFC propellant gas which acts on the medication container, and a capillary tube (14) which acts as a choke. The invention calls for the propellant-gas chamber to be designed to accommodate a pressure of more than 2.5 bar over atmospheric and the propellant gas to be 1,2-dichlorotetrafluoroethane (C2Cl2F4).
(FR) Pompe à perfusion implantable, comportant un récipient à médicaments souple (10), un récipient à gaz propulseur (12) agissant sur ce premier avec un gaz propulseur constitué d'un hydrocarbure fluoré, ainsi qu'un capillaire (14) pour l'étranglement, le récipient à gaz propulseur étant conçu pour une pression de remplissage de plus de 2,5 bars au-dessus de la pression atmosphérique, et le gaz propulseur étant du 1,2-dichlorotétrafluoréthane (C2,Cl2F4).
