  • Publication number: 20190336659
    Abstract: Systems and methods are provided for depleting platelets from blood. The system includes a multi-stage blood separation chamber in which blood is separated into red blood cells and platelet-rich plasma. The platelet-rich plasma is conveyed from a first stage of the chamber to a second stage, where it is separated into platelets and platelet-poor plasma. The platelet-poor plasma is conveyed out of the chamber while the platelets are allowed to accumulate in the second stage of the chamber. When a controller of the system has determined that the maximum chamber capacity of platelets has been accumulated in the second stage of the chamber, the platelets are conveyed out of the chamber to a waste container. The cycle of separating blood into its components, accumulating platelets in the chamber, and then flushing the platelets from the chamber is repeated until a target platelet concentration of the blood is achieved.

  • Publication number: 20190313953
    Abstract: A colorimetric optical sensor device includes a broadband light source configured to emit a light that is exposed to a fluid in a vessel. At least a portion of the light is reflected off of the fluid and received by an optical spectrometer. The optical spectrometer analyzes at least a portion of the received light to determine a main wavelength of the light. A controller correlates the main wavelength to a corresponding hematocrit or free hemoglobin concentration and generates an output indicative of the hematocrit or the free hemoglobin concentration of the fluid. The hematocrit or free hemoglobin concentration information may be used by a separation assembly in which the colorimetric optical sensor device may be incorporated to modify a separation procedure in which the monitored fluid is to be separated or is a component or constituent of a previously separated biological fluid.

  • Patent number: 10300189
    Abstract: A system and method are provided for controlling fouling and complement protein activation during separation of plasma from whole blood using a spinning membrane separator. The separator includes a pair of relatively rotating surfaces spaced apart to define a gap therebetween, with at least one of the surfaces comprising a membrane that allows plasma to pass therethrough but substantially prevents the passage of red cells. In accordance with the method, the membrane material and membrane fabrication technique are selected so as that the resulting membrane both resists fouling and complement protein activation. In a specific embodiment, the membrane is has a smooth surface and substantially linear pores. The pores have a nominal diameter of less than 2 microns (so as to exclude platelets) and preferably a diameter of from 0.6 microns to 0.8 microns, as may be obtained by use of track-etching.

  • Publication number: 20190117870
    Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the spinning membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib or ridge associated with the spinning membrane that decreases the gap between the spinning membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously-collected whole blood into selected blood components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.

  • Patent number: 10207044
    Abstract: Systems and methods are provided for separating blood into two or more separated blood components. The system includes a blood separation chamber with a single stage having five ports connected thereto. The five ports include a blood inlet port, a red blood cell outlet port, a platelet-rich plasma outlet port, a platelet-poor plasma outlet port, and a buffy coat outlet port. In the single stage, blood may be separated into a variety of components, such as red blood cells and platelet-rich plasma or red blood cells, platelet-poor plasma, and buffy coat. Depending on the components into which the blood is to be separated, flow out of one or more of the outlet ports may be prevented.
