US 2007/0167904 A1 · FLUID TRANSFER DEVICE

Abstract

A fluid ducting assembly for enabling flow communication between a syringe and either one of a vessel and a dispenser for dispensing a fluid contained, a priori in the syringe or in the vessel. The fluid ducting assembly includes a base having a first member, a second member, and a third member for connection to and providing flow communication with the syringe, the vessel and the dispenser, respectively. The fluid ducting assembly further includes a flow controller within the base enabling any one of a flow path between the first member and the second member and a flow path between the first member and the third member. The flow controller has either a first operative position in which the flow path between the first member and the second member is enabled or a second operative position in which the flow path between the first member and the third member is enabled. The flow controller being readily switchable from its first operative position to its second operative position but not readily switchable from its second operative position to its first operative position.

Dependent claims

A fluid transfer device having a longitudinal axis for transferring fluid within a vial having a container portion, an upper, generally cylindrically shaped portion with a lower edge and an intermediate neck portion to a fluid device having a female connector, the fluid transfer device comprising:

a top wall;
a skirt connected to and extending generally perpendicularly from the top wall, the skirt including a protuberance that engages the lower edge of the upper portion in an engaged position, the skirt being formed with a plurality of circumferentially spaced apart, longitudinally directed slits that define flex members, each of the flex members being resiliently, flexibly connected to the top wall between adjacent pairs of the slits;
a cannula connected to the top wall and extending into the vial in the engaged position, the cannula includes a puncturing tip that is located between the top wall and a distal end of the skirt along the longitudinal axis;
a male connector extending generally perpendicularly from the top wall in a direction opposite the skirt, wherein the male connector is releasably, surroundingly inserted into the female connector in an assembled configuration;
and
a flow duct extending between the male connector and the cannula, the flow duct being positioned generally parallel to the longitudinal axis and the top wall being positioned generally perpendicular to the longitudinal axis.
