Abstract: A tube joining device includes a housing, a first subassembly, and a second subassembly. The housing defines an interior region. The housing includes a first contact. The first contact is electrically conductive. The first subassembly includes a tube joining subassembly. The tube joining subassembly is at least partially in the interior region. The second subassembly is configured to be coupled to the housing. The second subassembly includes a second contact. The second contact is electrically conductive. The second subassembly is configured to be coupled to the housing by an elongated dovetail joint. The first contact is configured to be in electrical communication with the second contact to form a connection including a ground connection, a data connection, a power connection, or any combination thereof.

Abstract: A tube opening device may include a mounting base defining a tube-receiving cavity, a first tube-engaging surface extending into the tube-receiving cavity, a first linear-motion actuator secured to the mounting base and configured to move the first tube-engaging surface between the first retracted position and a first extended position, a second tube-engaging surface extending into the tube-receiving cavity, a second linear-motion actuator secured to the mounting base and configured to move the second tube-engaging surface between the second retracted position and a second extended position, a third tube-engaging surface extending into the tube-receiving cavity, and a third linear-motion actuator secured to the mounting base and configured to move the third tube-engaging surface between the third retracted position and a third extended position.

Abstract: A tube opening device includes a body having a first side and a second side and including a tube-receiving cavity. The first side of the body includes a first belt system disposed on a first side of the tube-receiving cavity and a second belt system disposed on a second side of the tube-receiving cavity. The first and second belt systems are configured to apply pressure to a tube received in the tube-receiving cavity to open temporary seals and form a continuous tube.

Abstract: An apheresis system at least partially defines a chamber and includes centrifuge that is movable between lock and unlock states. The centrifuge includes a base, cover, lock assembly, and latch assembly. The cover engages the base and defines slots. The lock assembly is coupled to the base and rotates between latched and unlatched states. The lock assembly includes tabs and a protrusion. The tabs are in the slots of the cover. The protrusion at least partially defines a receptacle. The latch assembly is coupled to the base and includes a lever and engagement component attached thereto. In the latched state, the protrusion engages the engagement component to reduce or prevent rotation of the lock assembly. In the unlatched state, the lock assembly can rotate. In the lock state, the tabs are at least partially within the slots. In the unlock state, the cover is movable with respect to the base.
