  • Patent number: 11738288
    Abstract: The present invention provides an automated system and method to isolate nucleated blood cells from whole blood or bone marrow. A disc mounted to a centrifuge system with spinning rotor is used to manipulate cells by channeling fluids while subjected to high gravitational field. The disc embodies at least two axisymmetric processing stations connected by a circular channel. Each station contains multiple chambers connected by fluidic channels to controllably transfer fluids. First stage separation allows for the isolation of the buffy coat layer while the second stage separation utilizes gradient density fluids to isolate the targeted nucleated cells from the buffy coat layer in the spinning disc.

  • Publication number: 20140323284
    Abstract: A system for centrifugation and processing multi-units of blood simultaneously. The system having a plurality of equally spaced blood processing stations integrated to the rotor and spinning therewith around the axis of rotation. Each station is fit to receive a set of fluidly interconnected containers having blood for processing. Hydraulic means are used to automatically balance the rotor by having a mechanism to transfer fluid to special chambers on the processing stations in order to compensate for the weight variations of the multiple blood units mounted to the rotor. A Computer controls the centrifuge operations.

  • Patent number: RE45315
    Abstract: A whole blood collection system includes an automated pump/control unit and an accompanying disposable blood set. When combined and connected to a source of anticoagulant, these elements allow automatic priming of the blood set with anticoagulant and automatic collection of anticoagulated blood product according to three different collection modes. The unit's pump and the blood set are specially designed to cooperate during the collection process to assure that the collected product has a precise blood to anticoagulant ratio. During the collection procedure, the pump/control unit automatically collects data relating to the procedure. Additional data specifically identifying components of the blood set, such as the blood collection bag, along with identification data on the donor's registration form may be scanned into the pump/controller unit by a scanner associated with the unit; this facilitates positive sample identification and tracking.
