Patent ID: 7491197

Claim:
A fluid transfer device, comprising: a housing including a connector defining a lateral opening, the connector being configured to receive a syringe cone of a syringe; first and second piercing elements mounted in the housing, each piercing element including a flow channel, the first and second piercing elements substantially pointing away from one another; and a slide disposed in the housing, at least a portion of the slide being positioned between the first and second piercing elements, wherein the slide is configured to move relative to the first and second piercing elements between a first position where the flow channel of one of the first and second piercing elements is in flow communication with the flow channel of the other of the first and second piercing elements, and a second position where the flow channel of one of the first and second piercing elements is in flow communication with the lateral opening, wherein the slide is configured such that the insertion of the syringe cone into the lateral opening of the connector moves the slide between the first position and the second position, wherein the slide is disposed in the housing in a manner that substantially prevents twisting of the slide relative to the housing, and wherein a portion of the slide defines a removal channel that is disposed on an outer portion of the slide and extends along a longitudinal axis of the slide all the way to an extremity of the slide configured to be contacted by an end of the syringe cone.
