Publication number: 20140069861Abstract: The present invention is related to hemodialysis, and more particularly, to a dialyzer with improved efficiency of mass transfer across a dialysis membrane utilizing microchannel separation provided in accordance with embodiments of the present invention. In accordance with an embodiment, a dialyzer is provided comprising a plurality of semipermeable membrane sheets and a plurality of flow separators. The membrane sheets and flow separators are arranged in alternating configuration and coupled into a laminae stack defining a plurality of parallel microchannel layers. Each microchannel layer comprises a plurality of first microchannels and a plurality of second microchannels. The first and second microchannels of each microchannel layer are in fluid communication with each other via one of the plurality of membrane sheets therebetween. The dialyzer is characterized as having a high surface to volume ratio and a high mass transfer coefficient.Type: ApplicationFiled: April 15, 2013Publication date: March 13, 2014Applicants: HOME DIALYSIS PLUS, LTD., STATE OF OREGON acting by and through THE STATE BOARD OF HIGHER EDUCATION on behalf of OREGON STAInventors: STATE OF OREGON acting by and through THE STATE BOARD OF HIGHER EDUCATION on beh, HOME DIALYSIS PLUS, LTD.

Patent number: 8524086Abstract: Certain disclosed embodiments concern systems and methods of preparing dialysate for use in a home dialysis system that is compact and light-weight relative to existing systems and consumes relatively low amounts of energy. The method includes coupling a household water stream to a dialysis system; filtering the water stream; heating the water stream to at least about 138 degrees Celsius in a non-batch process to produce a heated water stream; maintaining the heated water stream at or above at least about 138 degrees Celsius for at least about two seconds; cooling the heated water stream to produce a cooled water stream; ultrafiltering the cooled water stream; and mixing dialysate components into the cooled water stream in a non-batch process.Type: GrantFiled: April 29, 2011Date of Patent: September 3, 2013Assignees: State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State University, Home Dialysis Plus, Ltd.Inventors: Richard B.
