Title
(EN) THRUST BEARING ASSEMBLY, DRIVE TRAIN, AND MEDICAMENT DELIVERY DEVICE
(FR) ENSEMBLE PALIER DE BUTÉE, ENTRAÎNEMENT ET DISPOSITIF D'ADMINISTRATION DE MÉDICAMENT
Abstract
(EN)
A thrust bearing assembly for guiding and driving a piston member having a lead (6) screw for dispensing a medium of a delivery device when the piston member is driven in a first axial direction is provided. The thrust bearing assembly comprises a thrust bearing means (20) for being integrated in the delivery device, a passageway for guiding the lead screw, and a rotary drive (12) means for driving the lead screw and being fitted into or onto the thrust bearing means while being rotatable with regard to the thrust bearing. Further, the thrust bearing means comprises a thrust face which limits axial movement of the rotary drive means when driving the lead screw in the first axial direction. A drive train and a medicament delivery device in which the thrust bearing assembly is integrated are also provided.
(FR)
L'invention porte sur un ensemble palier de butée pour guider et entraîner un élément piston qui possède une vis-mère (6) pour distribuer un milieu d'un dispositif d'administration lorsque l'élément piston est entraîné dans une première direction axiale. L'ensemble palier de butée comporte un moyen formant palier de butée (20) destiné à être intégré dans le dispositif d'administration, un passage pour guider la vis-mère, et un moyen d'entraînement rotatif (12) pour entraîner la vis-mère et qui est adapté dans ou sur le moyen formant palier de butée tout en pouvant tourner par rapport au moyen formant palier de butée. De plus, le moyen formant palier de butée comporte une face de butée qui limite le mouvement axial du moyen d'entraînement rotatif lors de l'entraînement de la vis-mère dans la première direction axiale. L'invention porte également sur un entraînement et sur un dispositif d'administration de médicament dans lesquels l'ensemble palier de butée est intégré.
