摘要： 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.

摘要： 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 determines a total blood volume for a donor based on donor weight, height and gender. The system comprises a touchscreen for receiving a confirming user input and a scanning device configured to scan a bar code associated with a donor. The system and method operate a plurality of draw and return phases.

摘要： 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.

摘要： A method of collecting plasma includes receiving donor parameters at a controller of a plasma collection device electronically from a donor management system. The method includes storing a target volume for raw plasma which is based at least in part on donor height and weight used to calculate total donor blood volume, the target volume for raw plasma based on the total donor blood volume. The method includes setting the target volume for raw plasma and controlling the plasma collection device to operate draw and return phases to withdraw whole blood from a donor and separate the whole blood into the plasma product and a second blood component comprising red blood cells and to return the second blood component to the donor. The controller operates the draw and return phases until a volume of raw plasma in the collection container equals the target volume of raw plasma.

摘要： A system for collecting plasma comprises a separator to separate whole blood from a donor into a plasma product and red blood cells, an anticoagulant line to introduce anticoagulant to the whole blood, a touchscreen, and a controller. The controller is configured to receive donor parameters electronically from a donor management system. The controller is configured to use a target volume for plasma product and/or raw plasma which is based at least in part on donor height and weight used to calculate total donor blood volume, the target volume for plasma product and/or raw plasma based on the total donor blood volume. The controller is configured to control the system to operate at least three draw and return phases to withdraw whole blood from a donor and separate the whole blood into the plasma product and the red blood cells and to return the red blood cells to the donor.

摘要： 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.
