  • Publication number: 20250099980
    Abstract: A blood processing device includes a controller and a scanner coupled to the controller. The scanner is configured to scan a two-dimensional barcode associated with a component of a disposable processing circuit that is configured to be used in combination with the blood processing device. The scanner transmits a signal to the controller based on information derived from the two-dimensional barcode, with the controller determining information encoded into the two-dimensional barcode based on the signal received from the scanner.

  • Patent number: 10729829
    Abstract: A method for automated processing of a blood product, the method comprising providing a reusable separation apparatus controlled by a microprocessing unit, said apparatus configurable with settings and configured to associate with a disposable circuit comprising a separator and in communication with a source blood product having a first concentration and first volume. The apparatus and disposable circuit are configured to flow the source blood product into an inlet of the separator and separate supernatant of the source blood product from a first outlet of the separator into a filtrate container. The apparatus and disposable circuit are also configured to separate platelets and remaining supernatant from a second outlet of the separator into a retentate container, wherein the platelets and remaining supernatant in the retentate container have a second concentration greater than the first concentration and second volume less than the first volume.

  • Patent number: 10441706
    Abstract: A fluid processing system for controlling fluid flow comprises a cassette having a defined passageway on a first side. The first side includes flexible sheeting disposed over the passageway. The system comprises a durable processing device configured to engage the first side of the cassette, the durable processing device comprising a valve actuator configured to engage the flexible sheeting at a valve location along the passageway. The system comprises a first pump configured to draw fluid away from the valve location along the passageway. The first pump is disposed downstream of the valve location. The system comprises a second pump configured to pump fluid towards the valve location along the defined passageway. The second pump is disposed upstream of the valve location. The first and second pumps are configured to operate in concert and configured to provide pressure to prevent collapsing of the flexible sheeting against the passageway during operation.
