Title
(EN) A FLUID INJECTING SYSTEM WITH NEEDLE RETRACTION BY VACUUM
(FR) SYSTÈME D'INJECTION DE FLUIDE ET SON PROCÉDÉ
Abstract
(EN)
A fluid injecting system (100) comprising an injector (A) having an injector body (10), a plunger shaft (30), a plunger assembly (20) having an inner plunger barrel (21 ) slidable within an outer plunger barrel (22), a fluid-cartridge (B) having a fluid (53) and a hypodermic needle (72) for injecting the fluid(53) at an injectable site. The fluid-cartridge (B) is configured to releasably engage with the injector (A). A vacuum (V) is created between the outer plunger barrel (22) and the inner plunger barrel (21 ) upon formation of a united plunger barrel (40). Also, forward movement of the united plunger barrel (40) transfers the fluid(53) from the fluid-cartridge (B) into the injectable site. The hypodermic needle (72) retracts within empty fluid-cartridge (B) due to release of the vacuum (V) and the injector (A) is disengaged from the fluid-cartridge (B) for reuse. Further, a fluid injecting method (300) is provided.
(FR)
L'invention concerne un système d'injection de fluide (100) comprenant un injecteur (A) ayant un corps d'injecteur (10), une tige de piston (30), un ensemble piston (20) ayant un tube de piston interne (21) pouvant coulisser dans un tube de piston externe (22), une cartouche de fluide (B) ayant un fluide (53) et une aiguille hypodermique (72) pour injecter le fluide (53) au niveau d'un site injectable. La cartouche de fluide (B) est configurée pour être en prise de façon amovible avec l'injecteur (A). Un vide (V) est créé entre le tube de piston externe (22) et le tube de piston interne (21) lors de la formation d'un tube de piston uni (40). En outre, un mouvement vers l'avant du tube de piston uni (40) transfère le fluide (53) de la cartouche de fluide (B) au site injectable. L'aiguille hypodermique (72) se rétracte dans une cartouche de fluide (B) vide en raison de la libération du vide (V), et l'injecteur (A) est séparé de la cartouche de fluide (B) en vue d'une réutilisation. En outre, l'invention concerne un procédé d'injection de fluide (300).
