摘要： An adaptive filter concentrate flow control system and method includes a filter system, a pumping system driving feed fluid, concentrate and filtrate flowing through the filter system and a flow control system controlling the pumping system to maintain optimum filtrate flow rates along a control curve in a transmembrane pressure--feed fluid rate--filtrate flow rate three dimensional space. Actual sensed operating point data is used to locate the control curve so as to assure an optimized filtrate flow rate at which reversible blocking of the membrane has begun to occur without irreversible plugging. The system is advantageously employed to control and maximize the flow of plasma in a plasmapheresis system.

摘要： A disposable diagnostic plasma filter dispenser includes a low cost disposable container and a rotor drive for rotationally energizing a rotor within the container. The disposable container is particularly suitable for drawing and dispensing blood samples for clinical analysis and includes a tube shaped outer wall having a frangible dispenser outlet cover, a close fitting inner tube supporting a filter membrane and a unitary rotor disposed for axel free rotation and axial translation within the inner tube in response to energization from the rotor driver. The rotor produces vortex enhanced filtration while maintaining a flow of filter fluid through the filtration gap and creating a transmembrane pressure.

摘要： A tubing or harness set is provided having first and second portions sequentially applicable to a microprocessor-controlled hemapheresis instrument for generating platelet concentrate. The first portion includes a reservoir having dual compartments and a separator. The instrument and the first portion of the harness set alternately collect whole blood from the donor and reinfuse packed cells into the donor while simultaneously continuously separating whole blood into packed cells and platelet-rich plasma. Upon collection of a predetermined quantity of platelet-rich plasma, the donor is disconnected form the phlebotomy needle of the harness, the first harness portion is removed from the instrument and the second harness portion is applied to the instrument. The second harness portion includes a separator for receiving platelet-rich plasma from the collection container of the first harness portion and separating such plasma into platelet concentrate and platelet-depleted plasma.

摘要： A disposable biomedical rotating filtration system for processing fluids in a closed environment includes a rotor mounted for rotation on a pivot pin, a seal between the rotor and pivot pin, an external permanent magnet drive mechanism, and a star shaped drive element mounted on the rotor for rotating the rotor in response to a magnetic field induced by the permanent magnet of the drive mechanism. The drive element on the rotor is stamped from an inexpensive non-permanent ferromagnetic sheet metal and has a configuration and position in relation to the center of said magnetic field such that said drive element receives sufficient torque for driving said rotor and sufficient seal force is applied on the rotor to provide fluid tight seal between the rotating rotor and the seal. The pivot pin is molded from a hard plastic material such as a polyamide base resin having a low coefficient of friction and good lubriciousness. The pivot pin is irradiated by gamma radiation for sterilization and modifying of the plastic material without degradation or loss of lubricious properties.

摘要： A timing and control mechanism for a centrifuge comprising a piston to which is attached a cam having cam surfaces which interact with flexible tubing to control the rate of flow through the tubing. The velocity of the piston in the centrifugal force field is determined by the resistance to flow of fluid which the piston displaces. The movement of the cam is therefore a measure of the speed and duration of the centrifugal force.

摘要： A blood donation unit in which a reduced outside diameter phlebotomy needle is employed to minimize donor discomfort. The blood flow if, however, maintained at a flow level similar to that obtained with standard gauge phlebotomy needles by a roller pump which provides a predetermined pressure differential between the ends of the phlebotomy needle. The blood is mixed with a predetermined ratio of anticoagulant immediately after passing through the phlebotomy needle. The ratio of whole blood to anticoagulant is independent of the volume of whole blood collected.

摘要： An attitude indicator device for detecting, indicating, and/or logging the positional attitude of an individual in response to deviation from a set of one or more reference angles. By way of example and not of limitation, the device is mounted on the thigh of a patient and measurements are taken from an acceleration sensor within the device. The acceleration measurements are communicated to a receiver when the measurements deviate from acceptable thresholds, whereby the receiver indicates an alert condition. The device may be employed within numerous medical related applications, for example, to facilitate preventing patient egress and the prevention/detection of patient falls.

摘要： A process for filtration of matter from a liquid suspension through a membrane uses a rotor within a concentric shell rotating with a surface velocity which, together with the rotor-shell gap and suspension viscosity, establishes vigorous vortex cells about the rotor. At least one of the rotor and shell surfaces include a filter membrane. Tangential velocity components at the membrane surface constantly sweep the membrane surface to limit cell deposition tendencies while constantly replenishing the medium to be filtered. The vortex cells are established along the length of the membrane despite the constant extraction of filtrate and the resultant change in physical characteristics of the suspension.
