Abstract

A fluid transfer device comprising: a housing; a core positioned in the housing for relative movement with the housing, the core having a bore having an inlet and an outlet spaced from the inlet, and first and second gate-receiving regions spaced from the inlet and the outlet; and an actuator operatively connected in the device to cause relative movement between said core and said housing. Also disclosed is a method of creating an aseptic connection using the fluid transfer device.

First claim

What is claimed is:

1 . A fluid transfer device, comprising: a housing; a core positioned in said housing for relative movement with said housing, the core having a bore having an inlet and an outlet spaced from the inlet, and first and second gate-receiving regions spaced from said inlet and said outlet; and an actuator operatively connected in said device to cause relative movement between said core and said housing.

2 . The fluid transfer device of claim 1 , further comprising first and second gates respectively positioned in said first and second gate-receiving regions.

3 . The fluid transfer device of claim 2 , further comprising a first connector and a second connector, said first connector comprising a third gate displaceable from said first connector, said second connector comprising a fourth gate displaceable from said second connector, said first connector being attached or attachable to said core, and said second connector being attached or attachable to said core.

4 . The fluid transfer device of claim 3 , wherein said first gate is movable from a stored position in said first gate-receiving region to a position in said first connector.

5 . The fluid transfer device of claim 3 , wherein said second gate is movable from a stored position in said second gate-receiving region to a position in said second connector.

6 . The fluid transfer device of claim 2 , wherein said core is disk-shaped, said first and second gate-receiving regions have a radius of curvature, and wherein said first and second gates have a radius of curvature that matches the radius of curvature of said gate-receiving regions.

7 . The fluid transfer device of claim 3 , wherein said first connector has a groove configured to slidingly receive said third gate.

8 . The fluid transfer device of claim 7 , wherein said core has a radially outwardly protruding region configured to be received by said groove.

9 . The fluid transfer device of claim 1 , wherein said relative movement is linear movement.

10 . The fluid transfer device of claim 3 , wherein said core comprises a first region configured to receive said third gate when said third gate is displaced from said first connector, and a second region configured to receive said fourth gate when said fourth gate is displaced from said second connector.

11 . The fluid transfer device of claim 3 , wherein said first and second gates are removably coupled to said core.

12 . A method of creating an aseptic connection, comprising coupling a first connector and a second connector to a valve core, the valve core having an inner bore, first and second gate-receiving regions and first and second gates respectively occupying said first and second gate-receiving regions; actuating said valve core to establish fluid communication between said first and second connectors through said inner bore; and further actuating said valve core to move said first connector into engagement with said first gate, and to move said second connector into engagement with said second gate.

13 . The method of claim 12 , further comprising removing said first and second connectors from said valve core after said first and second gates are respectively engaged in said first and second connectors.

14 . The method of claim 12 , wherein said valve core comprises first and second radially outwardly protruding regions, and wherein said first and second radially outwardly protruding regions respectively receive said first and second connectors when said valve core is actuated to establish fluid communication between said first and second connectors through said inner bore.

15 . The method of claim 14 , wherein said first and second connectors each hold a displaceable gate when said first and second connectors are coupled to said valve core, and wherein said first and second radially outwardly protruding regions respectively displace said first and second displaceable gates from said first and second connectors, respectively, when said valve core is actuated to establish fluid communication between said first and second connectors through said inner bore.
