  • Publication number: 20210312836
    Abstract: A blood flow assist device includes a flexible sleeve, at least one blood flow stimulator incorporated into the sleeve, and an actuator assembly coupled to the blood flow stimulator. The sleeve has a first portion configured to receive at least a portion of a arm and a second portion configured to engage a portion of a hand. The first and second portions of the sleeve properly position each blood flow stimulator on the arm. The actuator assembly individually controls and selectively actuates each blood flow stimulator to apply a stimulus to the arm to control blood flow through a vein in the arm or hand having a vein access device connected thereto. The blood flow assist device may be paired with a blood processing device, with a controller of the blood processing device controlling the actuator assembly based on a pressure and/or flow rate of blood into the blood processing device.

  • Publication number: 20210291200
    Abstract: Fluid separation chambers are provided for rotation about an axis in a fluid processing system. The fluid separation chamber may be provided with first and second stages, with the first and second stages being positioned at different axial locations. In another embodiment, at least one of the stages may be provided with a non-uniform outer diameter about the rotational axis, which may define a generally spiral-shaped profile or a different profile for fractionating a fluid or fluid component. One or more of the stages may also have a varying outer diameter along the axis. The profile of the chamber may be provided by the chamber itself (in the case of rigid chambers) or by an associated fixture or centrifuge apparatus (in the case of flexible chambers).

  • Publication number: 20210077708
    Abstract: Blood is conveyed from a source into a separator, which separates at least one target blood component from the blood. The target blood component is then conveyed out of the separator, with the procedure continuing until an initial target amount of blood to be processed has been conveyed from the source into the separator and the target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of the target blood component. An adjusted target amount of blood to be processed is then determined based at least in part on the difference between a target yield of the target blood component and the actual yield. The initial target amount of blood to be processed is then replaced with the adjusted target amount of blood to be processed when next executing the procedure.

  • Publication number: 20210043316
    Abstract: A system and method for collecting plasma includes drawing whole blood from a donor, combining anticoagulant with the whole blood from the donor, separating the whole blood into a plasma product and a second blood component and sending the plasma product to a collection container. A controller receives parameters over a network from a remote computer, receives a user input to confirm the a parameter and/or procedure, determines a target volume for plasma product and/or raw plasma based on the parameters and, in response to confirming the donor, controls the system to collect the plasma using draw and return phases.

  • Patent number: 10561784
    Abstract: A blood processing system includes a centrifuge and an optical monitoring system mounted at a stationary radial position with respect to the centrifuge. A flow circuit may be mounted within the centrifuge, with an umbilicus of the flow circuit extending outside of the centrifuge. A midsection of the umbilicus is orbited around a rotational axis of the centrifuge at a uniform first speed, which causes the centrifuge to rotate at a non-uniform second speed that is approximately double the first speed. The monitoring system is configured to view the flow circuit through a radial window of the centrifuge to determine a characteristic of the flow circuit. The yoke and/or umbilicus may occasionally move into position between the monitoring system and the window, so a controller of the monitoring system is configured to determine when unobstructed light reflected through the window by the centrifuge is received by the monitoring system.
