Abstract

L'invention concerne un dispositif de raccordement d'aiguille d'un système d'injection de médicament, un dispositif de filtration et un système d'injection de médicament équipé de ce dispositif de filtration. Selon l'invention, un dispositif de raccordement d'aiguille est installé sur l'extrémité d'un tube de rallonge pour permettre la réalisation de l'injection, le dispositif de raccordement d'aiguille comprenant une extrémité avant à laquelle une aiguille d'injection est couplée libérable et une extrémité arrière faisant corps avec la poignée extensible. Le dispositif de raccordement d'aiguille comprend une unité de type filtre faisant corps avec la poignée pour éliminer l'air ainsi que d'éventuelles matières étrangères contenus dans l'injection réalisée. Ainsi, l'invention offre d'importants avantages: le captage et l'élimination des matières étrangères à l'aide d'une structure dotée d'un espace de piégeage dispense de l'emploi d'un filtre perméable aux liquides classique, ce qui permet de réduire le coût de fabrication; l'utilisation d'une unité de type filtre faisant corps avec un dispositif de raccordement d'aiguille, en comparaison de l'art antérieur où ceux-ci sont indépendants, ce qui représente un réel bénéfice en termes de productivité et de coût de fabrication; et plus particulièrement, l'invention surmonte les contraintes liées aux diverses injections qui traversent directement un filtre.
