Abstract[English]
A medical injection device comprises a medication container having a movable piston; a push rod having a plurality of spaced-apart position setting means disposed along the length and selectively displacing the movable piston to dispense a medicament from the medication container; a push rod sheath configured to engage with the position setting means on the push rod and moving the push rod toward to the distal end of the medical injection device; an upper cylinder configured to engage with the push rod sheath and moving the push rod sheath toward to the distal end of the medical injection device; and a resilient member configured to move the push rod sheath toward the proximal end of the medical injection device. The prefilled injection device is used to deliver multiple doses of medication.[French]
Un dispositif d'injection médicale comprend un réservoir de médicament comportant un piston mobile ; une tige de poussée comportant une pluralité de moyens de réglage de position espacés disposés selon sa longueur et déplaçant sélectivement le piston mobile pour distribuer un médicament depuis le réservoir de médicament ; un fourreau de tige de poussée conçu pour coopérer avec les moyens de réglage de position de la tige de poussée et déplacer la tige de poussée vers l'extrémité distale du dispositif d'injection médicale ; un cylindre supérieur conçu pour coopérer avec le fourreau de tige de poussée et déplacer le fourreau de tige de poussée vers l'extrémité distale du dispositif d'injection médicale ; et un élément élastique conçu pour déplacer le fourreau de tige de poussée vers l'extrémité proximale du dispositif d'injection médicale. Le dispositif d'injection prérempli est utilisé pour administrer des doses multiples de médicament.
