Abstract
A method for the re-anticoagulation of platelet rich plasma in a blood apheresis system includes priming the blood apheresis system with anticoagulant, such that a volume of anticoagulant is transferred to a PRP container. The method may then transfer the anticoagulant within the PRP container to a red blood cell container, and collect a volume of platelet rich plasma within the PRP container. The platelet rich plasma may be collected in a plurality of cycles. Between collection cycles, the method may transfer a portion of the volume of anticoagulant from the red blood cell container to the PRP container.
Claims22
A method for the re-anticoagulation of platelet rich plasma in a blood apheresis system, the method comprising:
- priming the blood apheresis system with anticoagulant such that a volume of anticoagulant is transferred to a PRP collection container;
- transferring the anticoagulant within the PRP collection container to a second container;
- collecting a volume of platelet rich plasma within the PRP collection container, the volume of platelet rich plasma being collected in a plurality of cycles;
- transferring at least a portion of the volume of anticoagulant from the second container to the PRP collection container between each of the plurality of cycles.
A system for the re-anticoagulation of platelet rich plasma in a blood apheresis system, the system comprising:
- a PRP container for storing collected platelet rich plasma;
- a red blood cell container for storing collected red blood cells;
- means for priming the system with anticoagulant such that a volume of anticoagulant is transferred to a PRP container;
- means for transferring the anticoagulant within the PRP container to the red blood cell container;
- means for collecting a volume of platelet rich plasma within the PRP container, the volume of platelet rich plasma being collected in a plurality of cycles;
- and
- means for transferring at least a portion of the volume of anticoagulant from the red blood cell container to the PRP container between each of the plurality of cycles.
