A quick disconnect coupling can include a first part and a second part. The first part can define a primary fluid passageway and a secondary fluid passageway and can include a first valve movable between open and closed positions to control flow through the first part secondary fluid passageway. The second part can define a second part defining a primary fluid passageway and a secondary fluid passageway and can include a second valve movable between open and closed positions to control flow through the second part secondary fluid passageway. In one aspect, the second part is removably connectable to the first part such that, when connected the first and second part primary passageways are placed in fluid communication with each other and the first and second valves are operable between the open and closed positions to selectively place the secondary fluid passageways of the first and second parts in fluid communication with each other.

A dry disconnect device including a first portion defining an outlet and an outlet portion of a fluid pathway and a female valve disposed within the first portion having an extended position, including the female valve being configured to seal the outlet portion, and a retracted position. A second portion defining an inlet and an inlet portion of the fluid pathway is lockingly engageable with the first portion. A male valve is disposed within the second portion including a male valve transition member configured to translate the male valve from an extended position to a retracted position including the male valve being configured to seal the inlet portion. The extended position of the male valve causes the female valve to transition from the extended position to the retracted position and causes the outlet portion and the inlet portion of the fluid pathway to be in fluid communication with each other.

Described here are systems and methods for a reusable, aseptic connector. A connector system provides aseptic fluid connection. The connector system has an inlet connector assembly having an inlet fluid passageway and an inlet valve configured to seal the inlet fluid passageway when in a disconnected state. The connector also has an outlet connector assembly having an outlet fluid passageway and an outlet valve configured to seal the outlet fluid passageway when in a disconnected state. The inlet valve is configured to couple to the outlet valve to form an aseptic fluid connection between the inlet and outlet fluid passageways when in a connected state.

A fluid coupling (R) comprising a male element (A) and a female element, a ring delimiting an inner channel of the female element (B), and a piston slidably mounted with respect to the ring (28) between a closed position and an open position of the inner channel. Between a disconnected configuration of the coupling and the connected configuration, the ring is moved rotationally with respect to the female body and the ring is held longitudinally in the female body, the piston is moved longitudinally from its closed position to its open position. The male body comprises an outer body and an inner body, the inner body delimiting an inner duct of the male element (A). During connecting, the outer body and the ring are rotationally fixed around the central longitudinal axis. In the connected configuration, the outer body and the ring are rotationally fixed. During connecting and in the connected configuration, the outer body and the inner body are free to rotate but unable to move in translation. The female element (B) comprises at least one locking device (45) movable between a position locking the rotation of the ring, and a release position, and in the disconnected configuration, the locking device (45) does not prevent the rotation of the ring.

A connector assembly includes a male connector and a female connector. The male connector comprises a male connector housing, a male connector valve core, and a male connector push rod. The female connector comprises a female connector housing, a female connector valve core, and a female connector push rod. The male connector valve core has a closed position, the female connector valve core has a closed position, and the male connector is capable of being at least partially inserted into the female connector. When the male connector is inserted to a proper place in the female connector, the male connector push rod pushes the female connector valve core away from the closed position, and the female connector push rod pushes the male connector valve core away from the closed position, so that the male connector fluidly communicates with the female connector.
