Abstract

A fluid transfer system ( 100 ) includes a transfer device ( 104 ) and an interface device ( 102 ). The transfer device ( 104 ) includes a fluid transfer member ( 164 ) and a transfer coupling member ( 125 ) to align the fluid transfer member ( 164 ) with the interface device ( 102 ). The interface device ( 102 ) includes a reservoir port ( 108 ), a fluid transfer member receptacle ( 144 ), an interface coupling member ( 124 ), and a reservoir valve ( 110 ). The interface coupling member ( 124 ) is configured to close the fluid transfer member receptacle ( 144 ) and to couple to the transfer coupling member ( 125 ) and open the fluid transfer member receptacle ( 144 ) to receive the fluid transfer member ( 164 ). The reservoir valve ( 110 ), e.g., a sliding seal, is configured to close the reservoir port ( 108 ) from the fluid transfer member receptacle ( 144 ) and to open the reservoir port ( 108 ) to the fluid transfer member ( 164 ) when the fluid transfer member ( 164 ) is positioned in the fluid transfer member receptacle ( 144 ). The fluid transfer member ( 164 ) can include a plunger assembly configured to open and close the reservoir port ( 108 ).

First claim

What is claimed is:

1. A transfer device comprising:
a body having a bore therethrough;
a coupling member configured to close the body and to couple to an interface device and open the body to the interface device; and
a transfer member slidably disposed in the bore of the body, the transfer member configured to extend through the coupling member and cooperate with the interface device to open a reservoir port of the interface device,
the coupling member comprising a disc, the disc having an opening to receive the transfer member, the disc being configured for rotation to bring the opening into alignment with the bore to permit the transfer member to extend through the opening into the interface device, the axis of rotation of the disc being parallel to the bore of the body.

2. The device of claim 1 , wherein the disc is configured to couple to a collar to cause rotation of the disc with rotation of the collar.

3. The device of claim 1 , wherein the disc includes a mating face configured to rotationally couple the disc to a corresponding disc of the interface device, such that the discs rotate together.

4. The device of claim 1 , wherein the transfer member comprises a plunger assembly.

5. The device of claim 1 further comprising one or more seals configured to provide a sterile barrier between the environment and a fluid path from the reservoir port to a transfer port, the transfer device maintaining a sterile path for fluid being transferred through the fluid path.

6. The device of claim 1 , further comprising an interlock configured for rotation with the disc of the coupling member, the interlock preventing the transfer member from extending toward the coupling member until the opening in the disc is aligned with the bore of the body.
