    Abstract: Mid-procedure termination of a mononuclear cell collection procedure may prevent collection of an amount of red blood cells that is required to harvest a complete mononuclear cell product. Blood separation systems and methods are provided for minimizing the impact of or recovering from mid-procedure termination of such a mononuclear cell collection procedure. According to one approach, blood or separated red blood cells are conveyed into a red blood cell collection container relatively early in the procedure to minimize the impact of a later termination of the procedure. According to another approach, blood and/or separated red blood cells within a fluid processing assembly are redirected through the fluid processing assembly following mid-procedure termination to allow for at least partial mononuclear cell collection. According to yet another approach, a double-needle fluid processing assembly may be converted into a single-needle configuration to allow for continued processing following mid-procedure termination.

    Abstract: A system for performing an apheresis procedure on a human subject includes an apheresis device having a communication channel in communication with a data storage device remote from the apheresis treatment device, an input device configured to receive an identity input data, wherein the identity input data comprises a combination of data, and a processing circuit. The processing circuit is configured to compare the identity input data to an identity of a human subject downloaded from the data storage device and, if the combination of data is consistent with two or more subject-specific information for a subject data entry, to provide access to an apheresis procedure operated according to the pre-programmed parameters on the apheresis device. The processing circuit is configured to derive an operating parameter for the apheresis procedure based on at least one of the subject-specific information of the human subject and to operate the apheresis procedure using the derived operating parameter.

    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.

    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.

    Abstract: A method and apparatus are provided for automatically detecting the type of replacement fluid loaded by the operator during a therapeutic exchange procedure and to provide a warning alarm if an incorrect fluid is used. After the operator connects the container of replacement fluid to the replacement fluid line of a single-use kit and enters into the controller an identification of the exchange procedure to be performed, the replacement fluid is flowed through a segment of the kit in proximity to a sensor associated with the hardware component that detects the type of fluid flowing through the segment. The controller verifies whether the replacement fluid detected in the segment corresponds to that appropriate for the selected exchange procedure, and notifies the operator in the event that an incorrect replacement fluid has been loaded.
