A subsea connection system for connecting to a hub has a body with an interior passageway, a collet having a plurality of collet segments, an outer sleeve overlying the collet, and a poppet valve assembly positioned within the interior passageway of the body. The plurality of collet segments are movable between a locked position and an unlocked position. The poppet valve assembly is movable between an open position and a closed position in which the open position allows a fluid to flow through the interior passageway and the closed position blocks a flow of fluid through the interior passageway. The outer sleeve is movable so as to cause the plurality of collet segments to join to a hub.

An aseptic coupling arrangement can include a first coupling device and a second aseptic coupling device. In one embodiment, the first and second coupling devices are substantially similar, each having a main body defining a front face and a fluid passageway therethrough. A first connecting feature disposed on the main body of each coupling device may be provided for aligning and coupling the aseptic devices together. Each coupling device may also include a sealing member received in the main body and a membrane removably coupled to the main body front face to cover the sealing member. The first aseptic coupling device may also include a rotatable protective cover that is removably attached to the main body and connected to the membrane. In one embodiment, the removal of the protective covers away from two coupled main bodies, in a direction parallel to the front faces, causes removal of the membranes.

A coupling apparatus includes a first component having a first non-mechanical valve, a second component having a second non-mechanical valve, and a third component having a first end for coupling with the first valve and a second end for coupling with the second valve. The third component has an elongated bore such that when the first end is coupled to the first valve and the second end is coupled to the second valve, a passageway is defined therethrough. The coupling apparatus includes a breakaway portion disposed between the third component and the second component and the first and second valves automatically close when the second and third components are separated from one another.

Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device while a locking ring of the first aseptic device is in an indexed initial position, rotating the locking ring to a secured position in which a compressive force is created and in which a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device can removed thereby resulting in a first a first sealing member of the first aseptic coupling device sealing with a second sealing member of the second aseptic coupling device to form a sterile fluid passageway.

The present invention relates to a multi-coupling device of the plate type for the simultaneous connection of a plurality of hydraulic, electric and pneumatic lines through quick couplings. The device according to the present invention is characterized in that it comprises bayonet coupling means which allow the coupling of the two plates by means of the relative sliding of the mobile plate with respect to the fixed plate. By virtue of the presence of a dedicated hydraulic circuit which connects the female couplings of the fixed plate to one another, the multi-coupling device according to the present invention allows to separate the step of coupling of the plates from the step of hydraulic connection of the male and female couplings.
