Fluid transfer device

A container accessing assembly comprising:

• a housing;
• at least one shroud projecting from the housing, the shroud comprising:
• a plurality of segments terminating in a continuous annular edge, the plurality of segments together with the annular edge defining a plurality of openings;
• a plurality of protrusions, each of the plurality of protrusions projecting from the annular edge and terminating at a distal end positioned in one of the plurality of openings, the distal ends inwardly extending, the plurality of protrusions together with the annular edge defining a receiving volume sized to accommodate the closure portion of a container.

A shroud for connecting to a container having a closure portion, the shroud comprising:

• a housing;
• a plurality of segments terminating in a continuous annular edge and defining a plurality of openings;
• a plurality of protrusions circumferentially spaced and inwardly extending from the annular edge, the protrusions defining a receiving volume dimensioned to receive the closure portion of the vial, wherein the protrusions have a proximal end connected to the annular edge and a distal end positioned in the opening,
• whereby the protrusions deflect outwardly away from an initial position during contact and traversing of the closure portion of the vial and return to approximately their initial position when the closure portion of the vial passes the distal end of the protrusion,
• whereby the protrusions deflect inwardly towards the closure portion of the vial when a removing force is applied to the vial, thereby preventing removal of the vial.

A fluid transfer device, comprising:

• a housing adapted to receive a fluid container and a media container;
• a flow controller having an interior and an exterior, the flow controller at least partially slidably disposed in the housing, the flow controller comprising at least two fluid channels, at least one vent conduit, and a vent;
• a connector coupled to the housing and configured for fluid communication with the at least one fluid channel of the flow controller;
• and
• at least one shroud projecting from the housing, the shroud comprising:
• a plurality of segments terminating in a continuous annular edge and defining a plurality of openings;
• a plurality of protrusions, each of the plurality of protrusions projecting from the annular edge and terminating at a distal end positioned in one of the plurality of openings, the distal ends inwardly extending, the plurality of protrusions together with the annular edge defining a receiving volume sized to accommodate the closure portion of one of the fluid container or the media containers;
• wherein the flow controller is configured to slidably move between a first predetermined position wherein at least one of the fluid channels provides fluid communication between the fluid container and the connector, and a second predetermined position wherein at least one of the fluid channels provides fluid communication between the media container and the connector.

A method of transferring material among containers, the method comprising

• providing a fluid transfer device, the device comprising:
• a housing comprising a connector, the housing adapted to receive a fluid container;
• and
• a flow controller at least partially slidably disposed in the housing, the flow controller comprising at least one fluid channel in fluid communication with the connector optionally in combination with a vent lumen and/or a filter;
• receiving at least one container to the housing of the fluid transfer device;
• and
• slidably positioning the flow controller to provide fluidic communication between the at least one fluid channel and the fluid container, optionally in combination with a vent lumen and/or a filter.
