Abstract

A fluid control device (10) for use with a syringe and at least one medicinal vessel (28). The fluid control device includes a first port (13), a second port (12) for receiving the syringe, a third port (17) including an adaptor (20) having a fluid conduit member (24) extending into the interior of the medicinal vessel (28) when attached thereto and a flow control member (20′) selectively disposable from a first flow control position enabling a flow path between a first pair of two ports (12, 17) and second flow control position enabling a flow path between a second pair of two ports (12, 13). The flow control member (20′) is coupled to one, of the ports for manipulation between its flow control positions.

Claims

1. A fluid control device comprising at least a first port;

a second port for receiving a syringe;

a third port comprising an adaptor having a fluid conduit member extending into an interior of a medicinal vessel attached to said adaptor, and a flow control member displaceable between first and second flow control positions respectively enabling flow paths between first and second pairs of said at least three ports;

wherein one of said second and third ports is coupled to said flow control member and is rotationally displaceable between first and second control positions thereby correspondingly rotating said flow control member between said first and second flow control positions, said flow control member being coupled to said adaptor whereby the flow control member is rotated by rotating the vessel attached to said adaptor.

2. A device according to claim 1, wherein said adaptor is integrally formed with said flow control member, thereby constituting an integrally formed adaptor cum flow control member.

3. A device according to claim 2, wherein said integrally formed adaptor cum flow control member includes a weakened portion enabling a forced non-reversible detachment of said adaptor from said flow control member at the second flow control position.

4. A device according to claim 3, wherein said adaptor is coupled to said flow control member by interengaging means enabling a reversible screw-like detachment of said adapter from said flow control member at the second flow control position.

5. A device according to claim 1, wherein said flow control member is coupled to said second port.

6. A device according to claim 5, wherein said first pair of said at least three ports includes said first and third ports and said second pair of said at least three ports includes said second and third ports.

7. A device according to claim 5, wherein said first pair of said at least three ports includes said first and second ports and said second pair of said at least three ports includes said second and third ports.

8. A device according to claim 5 wherein said second port further comprises an in-line filter.

9. A device according to claim 1 wherein said adapter further comprises a venting conduit extending into the interior of the medicinal vessel.
