  • Patent number: 11383013
    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.

  • Patent number: 11386993
    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: 11383015
    Abstract: A method of collecting mononuclear cells includes separating plasma from cellular components of whole blood. The cellular components, which include mononuclear cells and red blood cells, are combined with plasma replacement fluid to form a first mixture. The mononuclear cells of the first mixture are separated from the red blood cells of the first mixture, which may be followed by extracorporeal photopheresis being performed on the mononuclear cells.

  • Patent number: 11383016
    Abstract: A method and automated system for processing blood in which the automated system includes a programmable controller, a database, and an interactive display screen for displaying information and receiving operator input. The programmable controller is configured to automatically control the system to perform the method. Upon activation of the system, the screen displays a listing of different blood processing procedures that may be performed using the system. The operator may then input into the controller an identification of a specified blood processing procedure that is to be performed, such that an initial list of parameters that are associated with the specified blood processing procedure are displayed on the screen. The operator may then input into the controller an identification of the parameters that are to populate the display screen during performance of the procedure and indicate a format in which the selected parameters are to be presented on the display screen.

  • Patent number: 11318239
    Abstract: Systems and methods for performing online extracorporeal photopheresis of mononuclear cells are disclosed. During a mononuclear cell collection cycle, blood is removed from a source and separated into a plasma constituent, a mononuclear cell-containing layer, and red blood cells, followed by the collection of a pre-product including at least a portion of the mononuclear cell-containing layer and at least a portion of the separated red blood cells. The mononuclear cell collection cycle may be repeated, followed by the production of a single mononuclear cell product using the collected pre-product(s). The mononuclear cell product is irradiated using a fixed dose of light, such that the mononuclear cell product is produced so as to have a predetermined volume and a predetermined hematocrit, regardless of the number of pre-products used to produce the mononuclear cell product. Following irradiation, at least a portion of the irradiated mononuclear cell product is returned to the source.

  • Patent number: 11311823
    Abstract: Blood in a separation chamber is separated into a red blood cell layer, a plasma constituent, and a mononuclear cell-containing layer. A portion of the plasma constituent exits the chamber via a plasma outlet, while a first portion of the red blood cell layer exits via a red blood cell outlet. A second portion of the red blood cell layer exits the chamber via the red blood cell outlet and is collected. At least a portion of the collected red blood cell layer may then be conveyed to the chamber via the red blood cell outlet to convey at least a portion of the mononuclear cell-containing layer out of the chamber via the plasma outlet for collection. A second portion of the plasma constituent may be conveyed out of the chamber via the plasma outlet to more fully collect the mononuclear cell-containing layer without the use of collected plasma.

  • Patent number: 11298446
    Abstract: A method is provided for calibrating a pump during a blood separation procedure that has at least a first and second state or phase where fluid is flowed to or from a reservoir by action of the pump. The state or phase of the procedure may be a priming state, a draw state, a separation state and a return state, and the pump calibration may be performed between consecutive performances of the same procedure state. The calibration is based on a variance between the volume of fluid predicted to be processed by the pump for the given state of the procedure and the actual volume processed based on the change of weight of the reservoir. Recalibration of the pump, if necessary, is accomplished before the performance of the second phase is commenced.
