Publication number: 20200147289Abstract: 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.Type: ApplicationFiled: January 10, 2020Publication date: May 14, 2020Inventors: Amit J. Patel, Samantha M. Planas, Walter T. Watts, Kyungyoon Min, Daniel R. Boggs

Publication number: 20200147294Abstract: Disclosed is a suction irrigator, including a tri-lumen tube which includes a normal-pressure irrigation lumen, a high-pressure irrigation lumen and a suction lumen, a manifold connected to the tri-lumen tube, two flexible tubes, a control unit and a dual-drainage tube connected to the two flexible tubes, where the cross-sectional area of the suction lumen is larger than that of the normal-pressure irrigation lumen, and the cross-sectional area of the normal-pressure irrigation lumen is larger than that of the high-pressure irrigation lumen; and the normal-pressure irrigation lumen and the high-pressure irrigation lumen are connected to one of the flexible tubes and the suction lumen is connected to the other flexible tube by means of the manifold; and flow rates of gas or liquid in the two flexible tubes are controlled by the control unit. The suction irrigator has a good irrigation effect and is convenient to use.Type: ApplicationFiled: January 15, 2020Publication date: May 14, 2020Inventor: Lee David Edwards
