  • Publication number: 20210402072
    Abstract: A system with container volume tracking includes a pump receiving a line connected to a tracked container, an air sensor to detect air in the line, and a controller coupled to pump and sensor. The controller is configured to monitor pump operation, and determine a volume removed from the container based thereon. If the volume removed is less than a first percentage of a target volume and there is air, continue operation after an air purge. If the volume removed is more than the first percentage and less than a second percentage and if there is air, prompt the user for an input, and continue operation after an air purge if a first input is received or end operation if a second input is received. If the volume removed is more than the second percentage and if there is air, end operation.

  • Publication number: 20210372391
    Abstract: A peristaltic pump system includes tubing with first and second tube collars. The system also includes a rotary peristaltic pump with a tube channel having first and second ends, a first tube guide disposed at the first end and a second tube guide disposed at the second end. The first and second tube guides each include a passage with an inner diameter that is larger than the outer diameter of the tubing. The first tube guide has an unrestricted shoulder configured to abut the first tube collar in an installation state, and the second tube guide has an unrestricted shoulder configured to abut the second tube collar in the installation state. The first tube guide passage is disposed between its shoulder and the first end of the tube channel, while the second tube guide passage is disposed between its shoulder and the second end of the tube channel.

  • Publication number: 20210353841
    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the volume/weight of anticoagulated plasma that is collected is optimized. In one example, a nomogram is provided that utilizes the donor's hematocrit to calculate the volume/weight of raw plasma within a plasma product having the maximum volume permitted by the FDA nomogram. In a plasmapheresis procedure having multiple collection phases followed by a reinfusion cycle in which concentrated red blood cells are returned to the donor, the volume of plasma product to be collected is calculated prior to the start of each collection cycle to account for the donor's increasing hematocrit, thus resulting in a greater total volume of plasma product to be collected during the plasmapheresis procedure.

  • Publication number: 20210282684
    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which a volume of plasma product (i.e., anticoagulated plasma) so that that the targeted volume of pure plasma in the plasma product is determined based on donor-specific characteristics. In particular, the targeted amount of pure plasma to be collected is based on the weight, or the weight and the height, of the donor. The targeted volume of pure plasma to be collected, TVP, may be a multiple of the donor's weight. Alternatively, TVP may be a multiple of the donor's total blood volume, TBV, with the TBV of the donor being determined based on the donor's weight and height. A target volume for the plasma product to be collected, TVPP, is established, and separation of whole blood into a plasma component and a second component continues until the volume of plasma product in a collection container equals TVPP.

  • 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: 10762536
    Abstract: Instead of accepting competing ads and using an arbitration function (e.g., an auction) to choose winning ads to be served with a document, sets of ads (perhaps having different characteristics) can be generated, and an arbitration function can be used to select the winning set of ads. Such arbitrations on sets of ads can consider how ads, search results, colors, positions, fonts, etc., all interact with each other and affect the usefulness of the sets of ads to advertisers, end users, document publishers, and/or an ad serving entity.

  • Patent number: 10458920
    Abstract: A fluid separation system is provided for separating a plasma-containing fluid into separated plasma and a concentrated fluid. The system cooperates with a fluid flow circuit including a fluid separation chamber and a plasma outlet line associated therewith for removing separated plasma from the fluid separation chamber. The system includes an optical sensor assembly that receives a portion of the plasma outlet line when the fluid flow circuit has been associated with the fluid separation system. To ensure proper installation of the plasma outlet line, the optical sensor assembly compares light received by its light detector to a baseline value, which is indicative of the amount of light received by the light detector before the plasma outlet line has been installed. The amount of received light being equal to or less than a selected percentage of the baseline value indicates that the plasma outlet line has been properly installed.

  • Patent number: 10254916
    Abstract: A system is provided for processing blood from a blood source. The system cooperates with a disposable fluid flow circuit including a tubing line that is associated with a clamp of the system. The system also includes a sensor and a controller, which cooperate to determine whether the fluid flow circuit and/or the system itself is defective and/or if the fluid flow circuit has been installed onto the system improperly. If such an error or defect exists, then the controller determines whether a selected system state exists. The controller causes a change in the appearance of the display of the system, which includes displaying an interactive icon if the selected system state exists. The icon, when manipulated, causes the clamp to move from the closed condition to an open condition.

  • Patent number: 10220132
    Abstract: Apparatus, system and method are provided for controlling flow through a biological fluid processing device. Pressure of fluid flow through a flow path is monitored and flow rate in the flow path is increased or decreased based on sensed pressure levels for selected periods of time. This has particular application in controlling flow in an infusion or return flow path of an apheresis device that separates whole blood into one or more blood components.
