Title (EN) DOSE SETTING DEVICE
(FR) DISPOSITIF DE DOSAGE
Abstract: front page image
(EN)In a drug delivery device a dose to be apportioned from a cartridge is set by changing the relative position of co-operating dose setting elements (3, 5) and is injected by pressing a button (5) until this button abuts a stop (6). By operation of count up (7) or count down (8) buttons the dose is set and read into an electronic circuit (9) comprising a microprocessor and the dose setting movement of the dose setting elements relative to each other is performed by a motor (11) controlled by the circuit in accordance with the read in dose. The set dose is shown on a display (10). The motor (11) is further controlled to perform certain movements of the piston rod (3) so as retraction of this rod when a cartridge (1) is going to be changed an advancing of the piston rod to abutment with the piston (2) after the cartridge has been changed and further to advance this piston to expel air from the cartridge.
(FR)L'invention concerne un dispositif de dosage destiné à l'administration de médicaments à partir d'une cartouche, qui consiste à modifier la position relative des éléments de dosage coopérants (3, 5) et à injecter la dose par pression d'un bouton (5) poussé contre une butée (6). Des boutons de comptage progressif (7) ou dégressif (8) établissent la dose selon des valeurs transmises à un circuit électronique (9) qui comprend un microprocesseur. Le mouvement des éléments de dosage entre eux résulte d'un moteur (11) commandé par le circuit sur la base des valeurs saisies. La dose établie apparaît sur un affichage (10). Le moteur (11) est aussi commandé pour conférer certains mouvements à la tige (3) du piston, par exemple, rétraction de la tige lorsqu'une cartouche (1) est à changer et extension de la tige en butée avec le piston (2) après un changement de cartouche, et avance du piston pour chasser l'air de la cartouche.
