Title (EN) VARIABLE PROPORTION DISPENSER
(FR) DISTRIBUTEUR DE PROPORTIONS VARIABLES
Abstract:
(EN) The present invention is directed to a variable proportion dispenser and permits the user to adjust the proportions and amounts of the components dispensed from the cartridges during each delivery stroke. The variable proportion dispenser (2) includes a housing (4) which houses two pharmaceutical cartridges (6, 7). A reciprocating drive assembly (10) includes a drive stem (36, 37) extending from the piston (46) of each cartridge, a sliding body (66) mounted to the housing, and two one-way drive devices (54, 55) carried by the sliding body. Each one-way drive device includes a threaded dosage adjuster (60, 61), and a reciprocating, one-way driver (58, 59) which drives the drive stem into the cartridge. The distance the reciprocating driver can move on the return stroke away from the cartridge is adjustable by changing the threaded position of the dosage adjuster within the sliding body.
(FR) L'invention concerne un distributeur de proportions variables permettant à l'utilisateur d'ajuster les proportions et les doses des constituants distribués à partir des cartouches à chaque opération d'acheminement. Le distributeur (2) de proportions variables comprend un logement (4) logeant deux cartouches pharmaceutiques (6, 7). Un ensemble de commande à va-et-vient (10) comprend une tige de commande (36, 37) s'étendant à partir du piston (46) de chaque cartouche, un corps coulissant (66) monté sur le logement, et deux dispositifs de commande unidirectionnels (54, 55) portés par le corps coulissant. Chaque dispositif de commande unidirectionnel comprend un dispositif de réglage (60, 61) posologique fileté, ainsi qu'un dispositif de commande unidirectionnel à va-et-vient (58, 59) entraînant la tige de commande dans la cartouche. La distance que le dispositif de commande à va-et-vient peut parcourir lors de sa course de retour, à l'opposé de la cartouche, est réglable par changement de la position filetée du dispositif de réglage posologique à l'intérieur du corps coulissant.
