Fluid transfer device
First Claim
1. A fluid transfer device having a longitudinal axis for use with a vial having a container portion, an upper, generally cylindrically shaped portion with a lower edge and an intermediate neck portion, said fluid transfer device comprising:
- (a) a top wall; and
(b) a resiliently deformable circumferential skirt connected to said top wall and downwardly depending therefrom for telescopically receiving the upper portion of the vial, said skirt having;
(i) a generally cylindrical body portion;
(ii) an angularly outwardly extending marginal portion including a distal end;
(iii) an angularly inwardly extending intermediate portion disposed between said body portion and said outwardly extending marginal portion, said inwardly extending intermediate portion including at least partially circumferentially-extending opposing protuberances for releasably gripping the vial, at least a portion of the marginal portion extending substantially directly from the protuberances; and
(iv) a cannula connected to said top wall and downwardly depending therefrom for extending into the vial received in said adapter, said cannula including a puncturing tip located between said top wall and said distal end along said longitudinal axis,wherein said skirt is formed with a plurality of circumferentially spaced apart longitudinally directed slits for defining flex members resiliently flexibly connected at said top wall between each adjacent pair of longitudinally directed slits of said plurality of circumferentially spaced apart longitudinally directed slits,wherein said outwardly extending marginal portions of said flex members positively assist in guiding said upper portion of said vial into said adapter through outward flexure of said flex members resulting in an expanded insertion angle for said vial, at least two opposing flex members of said plurality of said flex members include said at least two opposing protuberances on said intermediate portion to engage said vial in an engaged position.

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.

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. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
