Abstract
(DE)
Implantierbares Ventil (1) für eine Drainageeinrichtung zum Ableiten von Hirnwasser, mit: einem Ventilgehäuse (10), das einen Einlass (2) und einen Auslass (3) sowie einen Innenraum (4) aufweist, einer im Innenraum (4) angeordneten Ventilkörperanordnung (600), die beweglich im Innenraum (4) angeordnet ist, einem ersten Ventilsitz (5), wobei die Ventilkörperanordnung (600) dazu konfiguriert ist, sich zum Verschließen einer Strömungsverbindung zwischen dem Einlass (2) und dem Innenraum (4) des Ventilgehäuses (10) an den ersten Ventilsitz (5) anzulegen, einem zweiten Ventilsitz (7), der dem ersten Ventilsitz (5) gegenüberliegt, wobei die Ventilkörperanordnung (600) dazu konfiguriert ist, sich zum Verschließen einer Strömungsverbindung zwischen dem Auslass (3) und dem Innenraum (4) des Ventilgehäuses (10) an den zweiten Ventilsitz (7) anzulegen, und einer im Innenraum (4) angeordneten Federvorrichtung (800), die eine Federkraft auf die Ventilkörperanordnung (600) in Richtung auf den ersten Ventilsitz (5) ausübt.
(EN)
The invention relates to an implantable valve (1) for a drainage device for draining cerebrospinal fluid, having: a valve housing (10) which has an inlet (2), an outlet (3) and an interior (4); a valve body arrangement (600) movably disposed in the interior (4); a first valve seat (5), the valve body arrangement (600) being designed to bear on the first valve seat (5) so as to close a flow connection between the inlet (2) and the interior (4) of the valve housing (10); a second valve seat (7) which lies opposite the first valve seat (5), the valve body arrangement (600) being designed to bear on the second valve seat (7) so as to close a flow connection between the outlet (3) and the interior (4) of the valve housing (10); and a spring mechanism (800) which is disposed in the interior (4) and exerts a spring force on the valve body arrangement (600) in the direction of the first valve seat (5).
(FR)
L'invention concerne une valve (1) implantable pour un dispositif de drainage servant à évacuer du liquide céphalo-rachidien. La valve comprend : un boîtier (10) de valve, qui comporte un orifice d'entrée (2) et un orifice de sortie (3) ainsi qu'un espace intérieur (4); un ensemble corps (600) de valve disposé dans l'espace intérieur (4), qui est disposé de manière mobile dans l'espace intérieur (4); un premier siège (5) de valve, l'ensemble corps (600) de valve étant conçu pour être placé sur le premier siège (5) de valve pour fermer une communication fluidique entre l'orifice d'entrée (2) et l'espace intérieur (4) du boîtier (10) de valve; un deuxième siège (7) de valve faisant face au premier siège (5) de valve, l'ensemble corps (600) de valve étant conçu pour être placé sur le deuxième siège (7) de valve pour fermer une communication fluidique entre l'orifice de sortie (3) et l'espace intérieur (4) du boîtier (10) de valve; et un dispositif élastique (800) disposé dans l'espace intérieur (4), qui exerce une force élastique sur l'ensemble corps (600) de valve en direction du premier siège (5) de valve.
