Title
(EN) FLUID PRODUCT INJECTION DEVICE
(FR) DISPOSITIF D'INJECTION DE PRODUIT FLUIDE.
Abstract
(EN)
Disclosed is a fluid product injection device comprising: - a syringe comprising a vessel (1) containing fluid product to be injected, a piston (3) being arranged so as to be axially movable in the vessel (1) and a needle (2) provided with an injection tip (20) being attached to the vessel (1), - a piston rod (5) axially movable relative to the vessel (1) and cooperating with the piston (3) during injection in order to move it axially in the vessel (1), - a sleeve (10) arranged around the syringe, being axially movable relative to the vessel (1) between an idle position, in which the sleeve (10) does not cover the injection tip (20) of the needle (2), and a projecting position, in which the sleeve (10) covers the injection tip (20) of the needle (2), the sleeve (10) being in its idle position before actuation of the injection device, the sleeve (10) being moved towards its projecting position after the injection of the fluid product, the sleeve (10) being moved by the piston rod (5).
(FR)
Dispositif d'injection de produit fluide comportant : - une seringue comportant un réservoir (1 ) contenant du produit fluide à injecter, un piston (3) étant disposé axialement déplaçable dans ledit réservoir (1 ) et une aiguille (2) pourvue d'une pointe d'injection (20) étant fixée audit réservoir (1), - une tige de piston (5) déplaçable axialement par rapport audit réservoir (1 ) et coopérant avec ledit piston (3) lors de l'injection pour le déplacer axialement dans ledit réservoir (1 ), - un manchon (10) disposé autour de ladite seringue en étant axialement déplaçable par rapport audit réservoir (1 ) entre une position de repos, dans laquelle ledit manchon (10) ne recouvre pas ladite pointe d'injection (20) de ladite aiguille (2), et une position projetée, dans laquelle ledit manchon (10) recouvre ladite pointe d'injection (20) de ladite aiguille (2), ledit manchon (10) étant dans sa position de repos avant actionnement du dispositif d'injection, ledit manchon (10) étant déplacé vers sa position projetée après injection dudit produit fluide, ledit déplacement dudit manchon (10) étant réalisé par ladite tige de piston (5).
