Publication number: 20230285655Abstract: 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.Type: ApplicationFiled: March 3, 2023Publication date: September 14, 2023Inventors: Charles L. HAKE, Mark E. HILLAM, John PITTINGER, Bruce ELLINGBOE, Peter O'BRIEN, Dennis BEBIE, Hong Duc NGUYEN

Publication number: 20230277741Abstract: A pump for fluids includes a rotor sub-assembly, a tubing pressure block, an inlet guide, an outlet guide, and a tubing guard. The rotor sub-assembly includes at least one roller. The tubing pressure block includes a raceway and at least one projection. The tubing pressure block is movable between a first position and a second position. The inlet guide includes an inlet tubing channel and is disposed proximate to a first side of the tubing pressure block. The outlet guide includes an outlet tubing channel and is disposed proximate to a second side of the tubing pressure block. The tubing guard is configured to engage with the inlet guide and the outlet guide when the tubing guard is in a closed position and is configured to expose the rotor sub-assembly, the tubing pressure block, the inlet guide, and the outlet guide when in an open position.Type: ApplicationFiled: March 2, 2023Publication date: September 7, 2023Inventors: Bruce ELLINGBOE, Anne Baker ORAM, Hong Duc NGUYEN, Evan Christopher PROVAN, Mark Evan HILLAM, Charles L.

Patent number: 8944983Abstract: An apparatus for separating at least two discrete volumes of a composite liquid into components, comprising a valve design that facilitates loading and unloading of sets of blood bags. The valves comprise a jaw mounted on a shaft, the jaw being adapted to apply radio frequency energy to seal a tube, a stepper motor section, and at least two position sensors. The valve sections are mounted on an upper plate, and the stepper motor sections are mounted on a lower plate. A main radio frequency coil is selectively electrically coupled to each of the valves through a multiplexing switch.Type: GrantFiled: May 18, 2011Date of Patent: February 3, 2015Assignee: Terumo BCT, Inc.Inventors: Hong Duc Nguyen, Bruce Ellingboe, Darryl Hudock

Patent number: 8540614Abstract: An apparatus for separating at least two discrete volumes of a composite liquid into at least a first component and a second component, comprising a valve design that facilitates loading and unloading of blood bags and associated tubing and bag sets. The valves comprise a rotating head, mounted on a shaft, which assumes a “load” position. The head pivots to an “open” position, which secures the tube in its designated location, but which maintains an open lumen through the tube. When the head is in a “closed” position, blood components cannot flow through the tube. The valve apparatus comprises means for maintaining a constant pressure on the tube and contact with the tube as the tube is melted and sealed.Type: GrantFiled: November 20, 2012Date of Patent: September 24, 2013Assignee: Terumo BCT, Inc.Inventors: Bruce Ellingboe, Hong Duc Nguyen
