Title
(EN) DRUG DELIVERY SHUTTLE PUMP SYSTEM AND VALVE ASSEMBLY
(FR) SYSTÈME DE POMPE À NAVETTE D'ADMINISTRATION DE MÉDICAMENT ET ENSEMBLE SOUPAPE
Abstract
(EN)
A multiple pulse volume shuttle pump powered by a shape memory alloy (SMA) wire is disclosed. In some embodiments, a shuttle pump system may include a pump chamber, a valve operable with the pump chamber, and a wire coupled to a valve shaft of the valve for controlling a position of the valve. The shuttle pump system may further include a pin disposed within an inset pathway of a cam, wherein the pin is moveable between multiple positions of the inset pathway in response to actuation of the valve shaft.
(FR)
L'invention porte sur une pompe à navette à volume d'impulsion multiple alimentée par un fil d'alliage à mémoire de forme (SMA). Dans certains modes de réalisation, un système de pompe à navette peut comprendre une chambre de pompe, une soupape pouvant fonctionner avec la chambre de pompe, et un fil couplé à un arbre de soupape de la soupape pour commander une position de la soupape. Le système de pompe à navette peut en outre comprendre une broche disposée à l'intérieur d'un trajet d'insertion d'une came, la broche étant mobile entre de multiples positions de la voie d'insertion en réponse à l'actionnement de l'arbre de soupape.
