  • Patent number: 9616164
    Abstract: A device and method for detecting recirculation for an extracorporeal blood treatment apparatus and an apparatus with a device for detecting recirculation are based on targeted haemodilution by administration of a substituate bolus, causing a pressure change in venous and arterial branches of the extracorporeal circuit due to a viscosity change of flowing fluid. Recirculation is detected based on detection of the pressure change. The device includes a control unit cooperating with a device for conveying blood and a device for supplying substituate. The control unit provides an operating mode for detecting recirculation, in which blood flow rate is reduced during administration of a substituate bolus. With simultaneous substituate bolus administration and reduction of blood flow rate, the composition of fluid flow is optimized for detection of recirculation, so that fairly large pressure changes result in venous and arterial branches, thereby improving sensitivity and reliability of the measurement method.

    Abstract: A filter cleaning system and method utilizes stationary conduit frames to discharge a cleaning fluid onto a filter without requiring removal of the filter. An intake valve positions on a housing upper end for receiving the fluid from an external source. A primary conduit extends along a longitudinal axis of the housing to carry the fluid from the housing upper end to a housing lower end, and in proximity to the filter. A plurality of conduit frames join the primary conduit at predetermined intervals along the longitudinal axis of the housing. The fluid flows through the conduit frames. Each conduit frame includes a plurality of apertures oriented to face the filter and discharge fluid onto the filter. Throughout the process, the conduit frames remain stationary. Support rods provide longitudinal stability, while wedges provide lateral stability to the conduit frames. A release valve discharges fluid and debris after cleaning.
