Leaktight joining device for the aseptic transfer of a biopharmaceutical product between a chamber and a container

Leaktight joining device (40) intended for ensuring the aseptic transfer of a biopharmaceutical product between a chamber (10) equipped with a removable door (18) and a container (20) equipped a removable cover (28), comprising:

• stationary temporary clamping means (50) able to keep the container (20) clamped against the chamber (10) so that the removable cover (28) of said container (20) is sealingly held against the removable door (18) of said chamber (10);
• stationary unlocking means (60) able to transition the container (20) from an initial locking position where the removable cover (28) seals the container (20) to an intermediate unlocking position where the removable cover (28) is disengaged from the container (20) and is sealingly held against the removable door of the chamber (10) so as to ensure an aseptic communication between said container (20) and said chamber (10);
• stationary locking means (70) able to transition the container (20) from the intermediate unlocking position to a final locking position where said removable cover (28) once again seals the container (20);
• an annular functional ring gear (42) able to rotate about a geometric axis of rotation (R) so as to actuate the stationary unlocking means (60) and the stationary locking means (70) of the container (20);
• characterized in that the stationary temporary clamping means (50), stationary unlocking means (60), and stationary locking means (70) are mechanically linked to the annular functional ring gear (42) and are arranged so that the one-way rotation of said annular functional ring gear (42) about the geometric axis of rotation (R) successively causes the actuation of the stationary temporary clamping means (50) which ensures that the container (20) is held in position against the chamber (10), then the actuation of the stationary unlocking means (60) which ensures the transition to the intermediate unlocking position of the container (20), then the actuation of the stationary locking means (70) of the container (20) which ensures the transition to the final locking position of the container (20), and the actuation of the stationary temporary clamping means (50) of the container (20) in order to release the container (20).
