The monitoring of the supply of substitution liquid is based on the measurement of pressure waves, which are generated by the substitution liquid pump, in the extracorporeal blood circulation system. A disturbance in the supply of substitution liquid is inferred when the amplitude of the pressure waves exceeds a predetermined limit value. The amplitude of the pressure waves is preferably monitored in the venous blood line.Type: GrantFiled: November 22, 2002Date of Patent: December 14, 2010Assignee: Fresenius Medical Care Deutschland GmbHInventors: Wei Zhang, Ralf Wamsiedler

Patent number: 7850853Abstract: The invention discloses a kind of porous membrane filtration component for treating water, specifically it discloses a kind of suspending porous hollow fiber membrane bundle for treating highly turbid waste water. The component includes some porous hollow fiber membrane yarns and casting heads arranged at both ends of respective yarns, wherein the connections between the said casting heads and membrane filtration module are flexible connections, at least one end of the flexible connection the cast header is connected with a hollow tube or cord, and the membrane bundle hangs on the said membrane filtration module, suspending freely. The invention provides a suspending porous hollow membrane bundle that can effectively remove contaminants adhered to the surface of the membrane yarns, makes its membrane yarns difficult to rupture, has a longer service life, and produces water with steady quality.Type: GrantFiled: July 4, 2005Date of Patent: December 14, 2010Assignee: Zhejiang Environmental Engineering Company LimitedInventors: Yang Wu, Xiang Li, Zhiming Tong

Patent number: 7848475Abstract: A strainer for an emergency core cooling system (ECCS) in a nuclear power plant comprises a perforated strainer element that is immersed in a reservoir of cooling water, which is drawn through the strainer element into the emergency core cooling system. The side of the strainer element in contact with the cooling water has a contoured configuration for disrupting the formation of a flat bed of fibrous material that can trap small particulate material intended to pass through the strainer element. Incorporating this strainer element into an ECCS strainer enables the strainer to be made more compact, because the debris bed need not be spread over an unduly large area to prevent excessive head loss from the debris load in the event of a reactor loss of coolant accident. The strainer also incorporates a modular construction that uses individual strainer disc modules. Each disc module includes a perforated first disc part having a central opening and a perforated second disc part also having a central opening.Type: GrantFiled: May 3, 2005Date of Patent: December 7, 2010Assignee: Continuum Dynamics, Inc.Inventors: Andrew E. Kaufman, Alan J. Bilanin
