  • Multi-unit blood processor with rotating valves
    Patent number: 8540614
    Abstract: 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.
