Title (EN) MICRO PISTON PUMP
(FR) MICRO-POMPE À PISTON
Abstract:
(EN) A low-force, non-displacement, micro/miniature valve and/or pump assembly is provided. A tube component having a first side port coupled to an inlet portion and a second side port coupled to an outlet portion can be selectively moved to alternatively couple the side ports to a first or second piston pump chamber. First and second pistons can be actuated after positioning the tube component to either draw in fluid or push out fluid from either the first or second piston pump chambers during each actuation of the pistons. The fluid can be drawn in from a reservoir and can be expelled to a patient for providing a dose of the fluid to the patient.
(FR) L'invention concerne un ensemble micro-soupape ou soupape miniature et/ou micro-pompe ou pompe miniature, sans déplacement et à faible résistance. Un élément tube ayant un premier orifice latéral raccordé à une partie entrée et un second orifice latéral raccordé à une partie sortie peut être sélectivement déplacé pour raccorder alternativement les orifices latéraux à une première ou à une seconde chambre de pompe à piston. Des premier et second pistons peuvent être actionnés après le positionnement de l'élément tube pour aspirer un fluide ou expulser un fluide de la première ou de la seconde chambre de pompe à piston lors de chaque actionnement des pistons. Le fluide peut être aspiré à partir d'un réservoir et peut être envoyé vers un patient pour fournir une dose du fluide au patient.
