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.

The fluid transfer device as defined in claim 9 further including filter means disposed within said lower portion of said tapered bore for filtering fluid flowing through said tapered bore. 11. The fluid transfer device as defined in claim 1 in which said angularly outwardly extending marginal portion has a length at least one-third (⅓) the length of said generally cylindrical body portion. 12. The fluid transfer device as defined in claim 1 further including a connector portion extending generally perpendicularly from said top wall opposite said cannula. 13. The fluid transfer device as defined in claim 1 wherein each of said plurality of said flex members includes one of said protuberances, each of said protuberances engaging said lower edge of said vial in said engaged position. 14. The fluid transfer device as defined in claim 1 wherein said at least two protuberances of said intermediate portion extend generally around an entire circumference of said skirt and engage said lower edge in the engaged position. 15. The fluid transfer device as defined in claim 1 wherein said puncturing tip is located on said longitudinal axis generally on a plane defined by said intermediate portion. 16. The fluid transfer device of claim 1 wherein said marginal portion extends generally tangentially from the protuberances. 17. A fluid transfer device for use with a vial having an upper, generally cylindrically-shaped portion with a lower edge and a stopper mounted therein, an intermediate neck portion and a container portion for holding a fluid, the fluid transfer device comprising: a top wall positioned on a plane that is generally perpendicular to a longitudinal axis of the fluid transfer device; a generally cylindrical body portion extending generally perpendicularly from the top wall, the body portion defining a receiving area; an intermediate portion extending from the body portion, the intermediate portion including at least two inwardly extending, opposing protuberances for releasably gripping the vial in an engaged position; a marginal portion extending outwardly from the intermediate portion at a guiding angle, the marginal portion having a generally hollow, frustaconical-shape and a distal end; a cannula extending generally perpendicularly from the top wall coaxial with the longitudinal axis into the receiving area, the cannula having a puncturing tip that is located along the longitudinal axis between the top wall and the distal end; and at least two circumferentially spaced, longitudinal slits extending through the body portion, the intermediate portion and the marginal portion, the at least two longitudinal slits defining at least two flex members resiliently, flexibly connected to the top wall, at least one of the flex members having an intermediate circumferential width defined between the at least two slits proximate the intermediate portion and an end circumferential width defined between the at least two slits proximate the distal end, the end width being greater than the intermediate width, the marginal portion of the at least two flex members guiding the upper portion of the vial into the receiving area such that the at least two opposing protuberances engage the vial and the cannula extends into the stopper in the engaged position. 18.
