Patent

CA 2757953

A multi-dose injection system (108) is disclosed that allows for vacuum-assisted removal of air from an interconnected tubing set (110) and syringes (126, 127) and subsequent filling with fluid. The injection system (108) may include a bulk fluid container holder module (116) operable to hold one or more bottles (118, 120) of fluid for administration to a patient. The holder module (116) may include a vacuum source (240) that is selectively fluidly interconnectable to the tubing set (110). Air may be removed from the tubing set (110) and syringes (126, 127) by fluidly interconnecting the vacuum source (240) to the tubing set (110). Then the vacuum source (240) may be fluidly isolated from the tubing set (110) and the bottles (118, 120) fluidly interconnected to the tubing set (110), thereby allowing fluid from the bottles (118, 120) to fill the at least partially evacuated tubing set (110) and syringes (126, 127).

Cette invention concerne un système d'injection de plusieurs doses (108) permettant l'élimination de l'air présent dans une tubulure (110) et des seringues (126, 127) assistée par dépression, puis le remplissage de liquide,. Le système d'injection (108) peut comporter un module supportant des récipients de liquide en vrac (116) capable de tenir un ou plusieurs flacons (118, 120) de liquide à administrer chez un patient. Le module support (116) peut comprendre une source de vide (240) reliée de manière fluidique et sélective à la tubulure (110). L'air peut être éliminé de la tubulure (110) et des seringues (126, 127) en reliant de manière fluidique la source de vide (240) à la tubulure (110). La source de vide (240) peut ensuite être isolée de manière fluidique de la tubulure (110) et des flacons (118, 120) reliés de manière fluidique à la tubulure (110), ce qui permet au liquide des flacons (118, 120) de remplir ladite tubulure (110) et lesdites seringues (126, 127) au moins partiellement évacuées.
