  • Publication number: 20180039748
    Abstract: A system and method processes blood donation data for presentation on an operator interface. A handheld computing device has a touch screen display and a processing circuit to provide an icon associated with an executable application on a first display screen, the icon configured to be positioned along with icons for other executable applications on the first display screen. The processing circuit is to retrieve an indication of a need for a particular blood component, wherein the particular blood component is selected from the group comprising whole blood, double red cells and plasma. The processing circuit is to provide the indication of the need for a particular blood component to the display. The processing circuit is to provide to the touch screen display a remaining time or a date the blood donor is next eligible to donate a blood component based on a donation eligibility guideline.

  • Patent number: 9861736
    Abstract: Methods are provided for collecting platelet-rich plasma. A disposable flow circuit is mounted to a fluid processing device having a fluid separation chamber and an injection device. A fluid containing plasma and platelets is continuously conveyed from a fluid source into the fluid separation chamber and processed to produce platelet-rich plasma. At least a portion of the platelet-rich plasma is automatically conveyed from the fluid separation chamber into the injection device, which is directly connected to a pump device such that at least a portion of the platelet-rich plasma from the fluid separation chamber is automatically conveyed into the pump device prior to being conveyed into the injection device. The injection device with the platelet-rich plasma is then detached from the disposable flow circuit.

  • Patent number: 9731302
    Abstract: Methods are provided for identifying a disposable flow circuit in a blood processing system. At least a portion of the disposable flow circuit is positioned within a centrifuge that is rotatable about a rotational axis and has a high-G outer wall with a window facing radially away from the rotational axis. The disposable flow circuit is monitored through the window to detect the presence of an expected identification feature and/or an expected alignment feature. If the expected feature is detected, a blood separation procedure is initiated, with the procedure including monitoring the disposable flow circuit through the window to detect characteristics of a fluid within the disposable flow circuit. If the expected feature is not detected, an alarm condition is generated and initiation of the blood separation procedure is prevented.

  • Publication number: 20170225177
    Abstract: An optical monitoring system is provided for use with a blood processing system. The system includes a light source configured to illuminate a disposable flow circuit received in a centrifuge and a light detector configured to receive an image of the disposable flow circuit. A controller combines two or more of the images received by the light detector to generate a two-dimensional output. The output is used to control the separation of blood within the disposable flow circuit. The monitoring system may also be used to verify that the disposable flow circuit is suitable for use with the centrifuge or that the disposable flow circuit is properly aligned within the centrifuge. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge.

  • Patent number: 9662665
    Abstract: An optical monitoring system is provided for use with a blood processing system having a yoke that rotates an umbilicus about a rotational axis at a first speed, which causes rotation of an associated centrifuge at a second speed about the rotational axis that is different from the first speed. The system includes a light source configured to illuminate a disposable flow circuit received in the centrifuge and a light detector configured to receive an image of the disposable flow circuit to detect the location of an interface between separated blood compenents within the disposable flow circuit. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge and is configured to be in a fully operational mode for interface detection only when a transparent portion of the centrifuge is visible to the monitoring system.

  • Publication number: 20160114339
    Abstract: Systems and methods are provided for improving the flow rate of plasma being removed from a blood separation chamber during a blood separation procedure. The system includes a blood separation chamber in which plasma is separated from cellular blood components and an outlet line for removing the separated plasma from the blood separation chamber. A primary optical sensor assembly is associated with the blood separation chamber to directly monitor the interior of the blood separation chamber. A secondary optical sensor assembly is associated with the outlet line to monitor the separated plasma in the outlet line, with each optical sensor assembly checking for the presence of cellular components in the separated plasma. If the primary optical sensor assembly detects such a condition while the secondary optical sensor assembly does not, then a controller may take steps to resolve the conflict and continue the procedure.

  • Patent number: 9119914
    Abstract: A method is disclosed for priming a kit for use in a therapeutic apheresis procedure with previously-collected blood prior to flowing the patient's whole blood into the inlet line of the kit, as part of a procedure in which a selected blood component is separated from a patient's whole blood, and replaced with a previously-collected blood component. The operator enters into the controller of the separation device the hematocrit value of the previously-collected blood. Then, in response to prompts by the controller, the operator enters a target hematocrit value for the previously-collected blood and an identification of the portion of the kit to be primed. The identified portion of the kit is automatically primed with the previously-collected blood. The patient is then connected to the inlet line of the kit in response to a prompt from the controller and the therapeutic procedure is commenced.

  • Publication number: 20140357465
    Abstract: Systems and methods are provided for processing blood or a fluid containing blood plasma and platelets. The blood or fluid is continuously added into a fluid separation chamber, which is used to isolate platelet-rich plasma therein. At least a portion of the platelet-rich plasma is automatically transferred from the fluid separation chamber into an injection device, with the fluid separation chamber and the injection device comprising components of a disposable flow circuit, which may be a closed system. One or more injection devices may be connected to a collection container or a pump device of the disposable flow circuit.

  • Patent number: 8676600
    Abstract: Certain examples provide systems, methods, and apparatus to provide information regarding blood donation. Certain examples include a method for providing blood collection information to a donor. The method includes displaying a graphical representation of a donor's donation progress toward a goal for blood component collection to a donor via an executable application icon on a mobile device. The graphical representation is to provide a visual indication of the donor's donation progress toward a goal. The donor's donation progress toward the goal is based on data from a donation facility provided to the mobile device and is displayed via the graphical representation without the donor executing the application. The method includes facilitating access to additional blood donation information for the donor by executing the application via the graphical representation on the mobile device. The method includes facilitating donor action with respect to the blood donation information via the mobile device.

  • Publication number: 20130233394
    Abstract: Systems and methods for determining when a fluid supply container of a blood processing apparatus becomes empty. The system uses a scale to monitor and detect when a fluid supply container is empty based on the rate of change of the container weight and whether the container weight is below a pre-established threshold, and a controller receives a signal from the scale and controls the operation of a pump to stop pumping when the fluid supply container is empty.
