  • Patent number: 7780619
    Abstract: A blood processing machine has a compact configuration in which the first and second parts of the machine separate to open a gap between them. The actuators and sensors face into the gap such that when a cartridge with a fluid circuit is placed in the gap and the two parts are brought together closing the gap, the actuators and sensor engage the fluid circuit. One of the parts has an operator interface with a display that is preferably aligned with the gap in such a way that the frontal area of the machine is minimized.

  • Patent number: 7771580
    Abstract: Method and Systems for extracting a concentrated sample of particles include priming a concentrate reservoir by passing a fluid through the concentrate reservoir to remove air. The concentrate reservoir has a first end with an opening and second end with an opening. The second end of the concentrate reservoir is closed off, and particles are accumulated within the concentrate reservoir by use of a particle concentrator. Thereafter, the first end of the concentrate reservoir is closed off, isolating the concentrate reservoir from particle concentrator, from which the particles were obtained. The second end of the concentrate reservoir is thereafter opened, and the particles of the concentrated sample in the concentrate reservoir are extracted to a sample capture reservoir through the second end opening of the concentrate reservoir.

  • Patent number: 7749393
    Abstract: A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and/or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration.

  • Patent number: 7749383
    Abstract: A filter cartridge in a filter-in-filter design with an inner filter and an outer filter. A mechanism, for example crush ribs, connects an upper end plate of the outer filter and an upper end plate of the inner filter to prevent relative axial and radial movement therebetween when assembled. Relative axial or radial motion can create a rattling noise which is sometimes perceived as a low quality filter. The crush ribs are, for example, formed on an interior surface of the upper end plate of the outer filter, and the ribs engage an outer perimeter of the upper end plate of the inner filter. One or more of the ribs crush when the inner filter is installed into the outer filter to ensure tight axial and radial engagement between the filters.

  • Patent number: 7569142
    Abstract: An apparatus and method for treating dirty water or other liquids containing particles of varying size includes a magnetic treatment unit and a centrifugal separator through which the liquid flows as a stream in sequence. The magnetic treatment unit causes very small sized particles to agglomerate, nucleate or otherwise to be amassed into larger particles which are then more easily separated by the centrifugal separator.

  • Publication number: 20090159518
    Abstract: Calories in a juice can be reduced by selectively removing more sucrose than primary sugars, for example, glucose and fructose. An acceptable flavor profile can be achieved since the primary sugars have a higher perceived sweetness than sucrose. The food product processing system for reducing calories can include multiple stages for filtering the juice to produce a clarified low-calorie juice having an acceptable flavor profile.

  • Publication number: 20090101564
    Abstract: To provide a water activation piece for use in a flow passage for forming a more efficient water flow stirring state for activating water though the piece which is formed in a simple structure with limited flow passage length, and a structural arrangement of the water activation piece, and a water activation device using the water activation piece and a structural arrangement thereof. The water activation piece 4 is formed as a cylindrical body with a through hole 42 that includes an axis 41. Spiral grooves 43 are formed non-continuously or continuously on an inner surface and outer surface thereof so that when the axis of the water activation piece is established in the flow passage, the water activation piece axially rotates by the flow pressure. The spiral grooves 43 are formed in a rightward rotation (clock-wise) manner in plan view.

  • Patent number: 7501059
    Abstract: A biological fluid processing or fluid filtration system is provided having novel open and closed loop processing systems wherein the gases transferred into and out of the system during processing pass through a porous medium in upstream and/or downstream gas inlet or outlet housings or vents in a manner which precludes the fluid being processed or filtered from ever contacting the housings or vents. Each housing or vent is separated from the fluid by a column of gas in its respective transfer line. The upstream gas inlet housing or vent is in communication with the unfiltered biological fluid, and the downstream gas inlet housing or vent is in communication with the filtered biological fluid.

  • Patent number: 7494590
    Abstract: The present invention relates to a method of controlling a dialysis apparatus, which can be used, e.g., for hemodialysis, hemodiafiltration, or hemofiltration. Numerous alarms occur during treatments creating additional workloads for the operator. The present method of controlling the apparatus allows an automatic switch from a first control mode to another, thus allowing the treatment to continue without operator influence.

  • Patent number: 7485221
    Abstract: A wastewater treatment system treating excess wastewater from a sewer system includes a generally vertically oriented first shaft structure adapted to receive excess wastewater from the sewer system, a generally vertically oriented second shaft structure spaced apart from the first shaft structure, a connector passage extending between the shaft structures proximate lower ends of the shaft structures, and an effluent passage in fluid communication with the second shaft structure. The treatment system further includes a treating agent dispenser for introducing a treating agent into the wastewater to disinfect at least a portion of the wastewater. During a sufficient rain event, the wastewater flows from the sewer system into the first shaft structure, then through the connector passage and the second shaft structure, and into the effluent passage, such that flow time through the shaft structures is greater than flow time through the connector passage.
