Publication number: 20140209519Abstract: A blood purification apparatus which can maintain operability during a normal mode and visibility during a display mode, and which can smoothly and excellently confirm an operation status in any case of the normal mode and the display mode. The blood purification apparatus that performs blood purification treatment by purifying blood of a patient which is extracorporeally circulated includes a display device 2 which performs a display relating to the blood purification treatment. The display device 2 can switch the normal mode where an input operation relating to the blood purification treatment can be performed and a display relating to the blood purification treatment is performed and the display mode where the display relating to the blood purification treatment is exclusively performed. In the display during the display mode, a layout and a form of the display during the normal mode are maintained and enlargedly displayed.Type: ApplicationFiled: December 6, 2013Publication date: July 31, 2014Applicant: Nikkiso Company LimitedInventors: Tomohiro Furuhashi, Hiroaki Suzuki, Takayuki Hirano, Tomohiro Suzuki

Patent number: 8790511Abstract: A water filtering device includes a filter element and telescopically interconnected inner and outer cylinder units. Each of the inner and outer cylinder units has an open inner end and a closed outer end. A first space is formed in the inner cylinder unit. The filter element is disposed within the inner cylinder unit, and is adjacent to the inner end of the inner cylinder unit so as to define a second space between the filter element and the outer cylinder unit. The outer cylinder unit is movable on the inner cylinder unit, such that the outer ends of the inner and outer cylinder units are moved toward each other, thereby forcing water to flow from the second space into the first space through the filter element.Type: GrantFiled: December 1, 2011Date of Patent: July 29, 2014Inventor: Wender Yang

Patent number: 8790512Abstract: An indicator for the status of the filter is provided. The indicator comprises at least one erodable member in contact with the source fluid and a visual indication arrangement that permits a viewer to gauge the appearance of the erodable member to thereby gauge the filter status. The erodable member is eroded by interaction with the fluid or with an element within the fluid. The indicator may be incorporated as an integral component of a filter or may be a stand-alone device to be incorporated into a filter or filtration system.Type: GrantFiled: August 28, 2007Date of Patent: July 29, 2014Assignee: Strauss Water Ltd.Inventors: Haim Wilder, Abraham J.

Patent number: 8784668Abstract: In a regenerative dialysis system, in a method for controlling a regenerative dialysis system, and in a controller for a regenerative dialysis system, an embodiment of the system comprises an input pump that pumps fresh dialysate fluid into a dialyzer at an input rate. An output pump pumps used dialysate fluid from the dialyzer at an output rate. An ultrafiltration rate of the system is related to the output rate relative to the input rate. A sorbent cartridge filters the used dialysate fluid to generate the fresh dialysate fluid. A controller controls the ultrafiltration rate of the system in response to a flow rate of the dialysate fluid through the sorbent cartridge.Type: GrantFiled: October 12, 2010Date of Patent: July 22, 2014Assignee: Fresenius Medical Care Holdings, Inc.Inventor: Michael J Beiriger
