Patent

CA 2188953

The invention concerns a one-piece dispensing device which can be used for the contamination-free administration of medicaments (cytostatica) and is particularly suitable for use in ambulant treatment. The aim of the invention is to design a connector for connecting medicament (cytostatica) containers to the instruments by which the medicaments are administered, the connector being designed to prevent, without a complex apparatus, contamination of the medicament container surroundings during connection of the container and until its disposal. This is achieved according to the invention by the provision of at least one coupling member (1) to create a non-releasable connection with a medicament container, said coupling member (1) having an insertion pin (2) and barbed surfaces (10) to accommodate the medicament container. The coupling member (1) is non-releasably connected via a hose (3, 31) to a flexible container (4; 41) which can be filled exclusively with gas until the device is first used. The container (4; 41) is non-releasably connected to a further tubular outlet (6) and a mechanically actuated stop valve (5, 7) is incorporated in each of the connecting ducts (3, 31, 6).

L'invention concerne un distributeur fait d'une seule pièce qui peut être utilisé pour l'administration sans contamination de médicaments (cytostatiques) et convient particulièrement au traitement ambulatoire. L'objectif de l'invention est l'obtention d'un raccord permettant de raccorder des réservoirs contenant des médicaments (cytostatiques) aux instruments au moyen desquels les médicaments sont administrés, ce raccord devant empêcher, sans un appareillage complexe, la contamination de l'environnement du réservoir de médicaments pendant son raccordement et jusqu'à ce qu'il soit retiré de l'appareil. Cet objectif est atteint par le fait qu'au moins un organe de raccordement (1) sert à créer un raccordement non libérable avec un réservoir de médicament, ledit organe de raccordement (1) étant pourvu d'une pointe d'insertion (2) et de surfaces à aspérités (10) sur lesquelles vient se placer le réservoir de médicament. L'organe de raccordement (1) est relié, de façon non libérable, par l'intermédiaire d'un tuyau flexible (3, 31) à un récipient souple (4; 41) qui peut être rempli exclusivement de gaz, jusqu'à ce que le dispositif soit utilisé pour la première fois. Le récipient (4; 41) est relié, de façon non libérable, à un autre tuyau de sortie (6), et une vanne d'arrêt (5, 7), actionnée mécaniquement, est montée dans chacun des conduits de raccordement (3, 31, 6).
