Abstract
(DE)
Eine Vorrichtung zur dosierten Verabreichung eines injizierbaren Produkts umfasst: a) ein Gehäuse (1, 5) mit einem Reservoir (2) für das Produkt; b) einen Kolben (3), der bei einer Verschiebung in eine Vorschubrichtung auf einen Auslass (4) des Reservoirs (2) zu Produkt aus dem Reservoir (2) verdrängt; c) eine den Kolben (3) in Vorschubrichtung verschiebende Zahnstange (10) mit einer ersten Zahnreihe (11) und einer zweiten Zahnreihe (12); d) ein relativ zum Gehäuse (1, 5) in und gegen die Vorschubrichtung verschiebbares Antriebsglied (20), das bei einer Verschiebung in Vorschubrichtung die Zahnstange (10) mitnimmt; und e) ein relativ zum Gehäuse (1, 5) verschiebegesichert angeordnetes Sperrmittel (6), das mit einer der Zahnreihen (11, 12) zusammenwirkt, derart, dass es eine Verschiebung der Zahnstange (10) gegen die Vorschubrichtung verhindert und eine Verschiebung der Zahnstange (10) in Vorshcubrichtung erlaubt.
(EN)
The invention relates to a device for dosing the administration of an injectable product comprising: a) a housing (1, 5) with a reservoir (2) for the product; b) a piston (3) that pushes out the product from the reservoir (2) when it is displaced towards an outlet (4) of the reservoir (2) in the advance direction; c) a toothed bar (10) with a first row of teeth (11) and a second row of teeth (12) that displaces the piston (3) in the advance direction; d) a drive member (20) that can be displaced in and against the advance direction in relation to the housing (1, 5), which entrains the toothed bar (10) when it is displaced in the advance direction and e) blocking means (6) which is not displaceable in relation to the housing (1, 5) and which cooperates with one of the rows of teeth (11, 12) in such a way that it prevents the displacement of the toothed bar (10) against the advance direction and enables the displacement of the toothed bar (10) in the advance direction. The second row of teeth (12) has an elongated tooth space (17a) in which the blocking means (7) cooperating with the second row of teeth (12) engages when the toothed bar (10) is placed in a starting position before effecting a first administration.
(FR)
Dispositif pour l'administration dosée d'un produit injectable, caractérisée en ce qu'il comprend a) un boîtier (1, 5), avec un réservoir (2) pour le produit, b) un piston (3) qui, par déplacement dans le sens d'avancement vers une sortie (4) du réservoir (2), refoule du produit hors de ce réservoir (2), c) une crémaillère (10) déplaçant le piston (3) dans le sens d'avancement, comportant une première denture (11) et une deuxième denture (12), d) un organe d'entraînement (20), déplaçable par rapport au boîtier (1, 5) dans le sens d'avancement, ou à l'encontre de ce sens, et entraînant la crémaillère (10) lors d'un déplacement dans le sens d'avancement, et e) des moyens d'arrêt (6) disposés solidaires en déplacement par rapport au boîtier (1, 5), coopèrent avec l'une des dentures (11, 12), de manière à empêcher un déplacement de la crémaillère (10) à l'encontre du sens d'avancement, et à permettre un déplacement de la crémaillère (10) dans le sens d'avancement. La deuxième denture (12) présente une zone prolongée exempte de dents (17a) dans laquelle s'engagent les moyens d'arrêt coopérant avec la deuxième denture (12), lorsque la denture (10) occupe une position de départ, préalable à une première administration.
