The example method includes routing the plasma removed for collection. The example method includes re-filtering the remaining blood using a or the filtration device to remove additional plasma from the remaining blood. The example method includes routing the additional plasma removed for collection.Type: ApplicationFiled: June 7, 2013Publication date: October 31, 2013Inventors: Christopher J. Wegener, Daniel R.

Patent number: 8568589Abstract: Provided are a connection member capable of preventing leakage from a supply side to a permeating side from occurring by a simple means; and a separation membrane module using the connection member. The connection member (20) is used to connect in series a plurality of separation membrane elements equipped with end surface holding members (36) and to install the separation membrane elements in a pressure-resistant vessel (38). The connection member (20) is characterized in that, when the separation membrane elements are connected to each other, the connection member is engaged with respective grooves (36b) of the end surface holding members (36) adjacent to each other.Type: GrantFiled: February 20, 2009Date of Patent: October 29, 2013Assignee: Nitto Denko CorporationInventors: Yasuhiro Uda, Toshimitsu Hamada, Masashi Beppu, Shinichi Chikura, Nobuharu Tahara, Masakatsu Takata

Patent number: 8551331Abstract: An automatic filtering system for filtering a cooking medium in a fryer, includes a frypot; a filter manifold having removable filter; a pump, that supplies cooking medium from the filter manifold to the frypot; a pressure sensor that senses a pressure of the cooking medium supplied by the pump; and a controlling mechanism that controls an operation of the pump in response to the sensed pressure data. The control mechanism halts the operation of the pump after sensing a drop in the pressure of the cooking medium pressure that is greater than or equal to a predetermined pressure drop threshold. The systems and methods of the invention provide automatic filtering that may reduce or eliminate an incorrect refilling operation after the filtering of cooking medium, so that the filtering process may be performed correctly each time.Type: GrantFiled: May 29, 2009Date of Patent: October 8, 2013Assignee: Henny Penny CorporationInventors: Douglas A. Burkett, Thomas Lee Gort, Gary L. Mercer

Patent number: 8545698Abstract: Disclosed are hemodialysis and similar dialysis systems including fluid flow circuits. Hemodialysis systems may include a blood flow path, and a dialysate flow path including balancing, mixing, and/or a directing circuits. Preparation of dialysate may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit and/or the various fluid flow paths may be isolated from electrical components. A gas supply may be provided that, when activated, is able to urge dialysate through the dialyzer and blood back to the patient. Such a system may be useful during a power failure. The hemodialysis system may also include fluid handling devices, such as pumps, valves, mixers, etc., actuated using a control fluid, The control fluid may be delivered to the fluid handling devices using a detachable external pump. The fluid handling devices may have a spheroid shape with a diaphragm dividing it into two compartments.Type: GrantFiled: August 8, 2012Date of Patent: October 1, 2013Assignee: DEKA Products Limited PartnershipInventors: Michael J. Wilt, Jason A. Demers, Kevin L. Grant, Brian D. Tracey, James D. Dale

Patent number: 8540879Abstract: A device for separating blood into individual components and/or groups of components, in the form of a sterilizable system includes a filter arrangement forming inlet and outlet chambers using filter elements arranged therein, and respective receptacles for cellular blood components and for blood plasma. The inlet chamber can be connected to the blood source via a line on the inlet side to conduct the blood and is connected, on the outlet side, to the cellular blood components receptacle. The outlet chamber is connected to the blood plasma receptacle via a line on the outlet side. Thermal sterilization is used to sterilize the device by opening a respective line into the inlet-side line of the inlet chamber, into the inlet chamber and the outlet-side line of the outlet chamber, or into the outlet chamber, the line being connected to the exterior via a hydrophobic or hydrophilic filter.Type: GrantFiled: July 26, 2006Date of Patent: September 24, 2013Assignee: Hemacon GmbHInventor: Gerd H. Heim

Patent number: 8535536Abstract: A split thin-flow separations device can include a fluid channel having an inlet zone, an outlet zone, and a transport region between the inlet zone and outlet zone. The inlet zone includes a sample inlet and a carrier fluid inlet which are fluidly separated by an inlet splitter to minimize mixing of fluids from respective inlets in the inlet zone. The transport region can be a substantially open channel. Similar to the inlet zone, the outlet zone can include a sample outlet and a carrier outlet which are fluidly separated by an outlet splitter to segregate portions of a fluid into each of the two outlets as the fluid enters the outlet zone. A plurality of cross-flow inducers can also be oriented along a wall of the fluid channel in the transport region. The cross-flow inducers are oriented to form a cross-flow field across the transport region.Type: GrantFiled: July 2, 2010Date of Patent: September 17, 2013Assignee: University of Utah Research FoundationInventors: Bruce K.
