Dry disconnect/bubble free coupling for blood transfer
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.

COUPLING ELEMENT FOR A HYDRAULIC COUPLING
A coupling element for a pressure medium line hydraulic coupling includes a housing, a sleeve inner body, a pressure casing and a valve tappet. The housing has a flow channel for pressure medium. At least the inner body, the casing and the tappet can be shifted, during coupling, from a starting position, along the coupling axis in a first direction into a coupling position where a block secures a coupling plug to the coupling element. They can be shifted from the coupling position in a second direction opposite the first direction, along the coupling axis into a stop position blocking further movement of the casing in the second direction. The inner body and the tappet are moveable further in the second direction into an open position where a flow cross-section is released between the casing and the tappet and a lock acts on the inner body and the tappet.
RAPID-CONNECT COUPLER AND RECEPTACLE HAVING ANTI-ROTATION FEATURE
A rapid connect coupler for connecting a fluid holding tank to a receptacle in a non-rotatable manner can include a housing, a probe configured to translate in a longitudinal direction within the housing, and a handle assembly configured to cause the probe to translate within the housing. The handle assembly can be movable between a plurality of positions corresponding to decoupled, coupled and venting positions. The coupler can also include a slidable sleeve coupled to an outer surface of the probe and configured to translate with the probe in the longitudinal direction, the sleeve including a collar configured to engage the receptacle in the coupled and uncoupled positions to prevent rotation of the coupler with respect to the receptacle when the two components are engaged to one another.
Sterile Connection/Disconnection Coupling And Method
Fluid transfer device and method that allows for sterile wet connections, allows the connection to be reversed, and allows the connection to be reconnected, while leaving the connectors sterile and reusable under pressure. In certain embodiments, the device includes a first member and a second member, the latter adapted to receive the former in locking engagement upon actuation of the device to create fluid communication between the two in a sterile manner. Each of the members include a door that when opened, allows the first member to be linearly displaced into the second member to allow fluid to be transferred. When fluid transfer is complete, the first member can be retracted from the second member, and the doors closed.

Fluid system connection nozzle assembly
A connection nozzle assembly includes an inner fluid product tube, a tube sleeve secured about the fluid product tube, an outer nozzle sleeve, and a locking mechanism disposed between the fluid product tube and the nozzle sleeve. The nozzle sleeve includes a body portion and a rear portion, each being moveable between a plurality of locking positions. The nozzle assembly includes one or more grips configured to rotate forward and backward to lock and unlock the nozzle assembly to a receptacle coupling, respectively. The nozzle sleeve is moved between the plurality of locking positions, thereby engaging the locking mechanism to secure the connection nozzle assembly to a receptacle coupling. The connection nozzle assembly can be uncoupled by reversing the nozzle sleeve.

Female quick coupling and quick connector comprising said female quick coupling
The present invention relates to a female coupling and the respective female-male connector, the female coupling being adapted to be connected to and disconnected from a corresponding male coupling by means of pushing and pulling actions, respectively, said female coupling and male couplings comprising a female valve assembly and a male valve assembly respectively, each of said female and male valve assemblies being adapted to be alternatively translated forwards and backwards between a first closing position and a second opening position, wherein the flow of a fluid is possible between the female coupling and male coupling with said female and male valve assemblies in the respective opening positions, wherein said female coupling comprises mechanical locking means adapted to prevent the accidental switching of said female valve assembly from its said second opening position to its first closing position even in case of fluid flow from the male connector to the female connector.
