Abstract

A transfer device for pharmaceuticals comprising a housing which has an open bottom permitting insertion of a vial within the housing, a piercing member mounted within the housing and having an interior passageway formed therein, a connector for a syringe located on top of the housing, and a moveable member mounted within the housing, the moveable member being moveable from a first position preventing access to the piercing member and a second position permitting access to the piercing member when the vial is inserted in the housing.

Claims

1. A transfer device comprising:

a housing (24) having a top, a side wall (26), an open bottom, said open bottom permitting insertion of a vial (12) within said housing;

a piercing member (34) mounted within said housing (24), said piercing member (34) having a piercing tip (36) located at a bottom end thereof, said piercing member having an interior passageway formed therein;

a connector (30) located on an exterior side of said top;

a moveable member (40) mounted within said housing (24), said moveable member (40) being moveable from a first position wherein said moveable member (40) prevents access to said piercing tip (36) and a second position permitting access to said piercing tip when said vial is inserted in said housing.

2. The transfer device of claim 1 wherein said moveable member (40) and said housing (24) cause said moveable member (40) to rotate when said moveable member (40) moves upwardly upon insertion of said vial (12), said moveable member returning to a third locked position upon removal of said vial, said third locked position being such that a further vial cannot be inserted into said housing.

3. The transfer device of claim 1 wherein said moveable member includes at least one leg (46), said housing having a recess formed therein, said leg engaging said recess when said moveable member is in said second position, said moveable member being returnable to said first position upon removal of said vial by pressure on said leg to release said leg from said recess.

4. The device of claim 2 wherein said piercing member is selected from the group consisting of a needle or spike.

5. The device of claim 4 wherein said moveable member (40) has a centrally located aperture (44) to permit said piercing member (34) to pass therethrough.

6. The device of claim 2 wherein said connector (30) on the exterior side of said top comprises a luer connector.

7. The device of claim 3 wherein said moveable member (40) has two projections, each projection being located on a respective one of diametrically opposite legs.

8. The device of claim 7 wherein said housing (24) has a recess formed on an interior surface thereof to receive a disc portion of said moveable member (40) when said moveable member is in said first position.
