CA 2641643

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

Procédé de distribution d'un fluide thérapeutique à partir d'une ligne comprenant l'installation d'une ligne d'entrée à connecter à une source de fluide située en amont. En aval, la ligne d'entrée est en communication fluidique avec une chambre de pompage. La chambre de pompage comprend une sortie de pompe. Le procédé comprend aussi l'actionnement d'un ensemble d'application de force de manière à limiter l'écoulement rétrograde de fluide à travers l'entrée tout en mettant sous pression la chambre de pompage pour pousser l'écoulement à travers la sortie de pompe. Un système correspondant emploie le procédé.
