    摘要： A configurable automated blood component manufacturing system includes a durable hardware component and a single use fluid flow circuit. The hardware component includes a pump station, a centrifuge, and a controller including a touchscreen. The hardware component further includes hangers for suspending containers, a weight scale associated with each hanger, a plurality of tubing clamps, and a cassette nesting module including a plurality of valves and pressure sensors. The fluid flow circuit includes a separation chamber received in the centrifuge, a fluid flow control cassette mounted in the cassette nesting module, and a plurality of containers in fluid communication with the fluid flow cassette. The controller is pre-programmed to automatically operate the system to perform one or more standard blood processing procedures selected by an operator by input to the touchscreen, and is configured to be further programmed by the operator to perform additional blood processing procedures.

    摘要： Methods and systems for bidirectional priming of a blood circuit while a catheter is connected to the circuit that delivers gas-enriched blood to a patient. The system primes the circuit while the catheter is connected to the circuit by controlling a first flow control mechanism to close to prevent blood flow through the draw line to a catheter and causes a pump to circulate blood in a first direction through a mixing chamber and/or through a bubble trap that removes air bubbles from the circuit. The system controls a second flow control mechanism to close to prevent blood flow in a return line to the catheter while causing the first flow control mechanism to open after the second flow control mechanism is closed and while causing the pump to circulate the blood in a second, opposite direction through the mixing chamber that removes air bubbles from the circuit.

    摘要： A primer may be used with IV catheter systems. The primer may be positioned along the tubing of an extension set such that the primer divides the IV catheter system into a downstream portion and an upstream portion. The primer may vent air from both the upstream and downstream portions to allow blood to flow up to the primer while also allowing priming solution to flow down to the primer. As a result, the catheter may be inserted into the patient's vasculature without first priming the catheter. Once the air has been vented from the upstream and downstream portions of the IV catheter system, the primer may be actuated to open a fluid pathway through the primer. With the fluid pathway opened, the priming solution may commence flowing towards the patient's vasculature thereby flushing the blood from the IV catheter system.
