Patent number: 10420872Abstract: The degassing system can include a degassing vessel and can utilize a vacuum pump and a fluid pump located downstream of the degassing vessel to control the pressure within the degassing vessel in order to control the concentration of gases in fluid exiting the degassing system. The degassing system can further comprise sensors in communication with the pumps to control the rate of flow and pressure through the degassing system. The degassing system may be placed in a dialysate flow path to remove dissolved gases including carbon dioxide from the dialysate.Type: GrantFiled: June 9, 2017Date of Patent: September 24, 2019Assignee: Medtronic, Inc.Inventors: Thomas E. Meyer, William P. Hajko, Daniel Jordan Bloomberg

Patent number: 10195327Abstract: A sensing and storage system for fluid balance during dialysis is provided. The sensing and storage system has flow sensors on either side of a dialyzer in a controlled volume dialysate flow path. The sensors are positioned so that no fluid can be added to or removed from the dialysate flow path between the sensors except for that which is added or removed by action of a control pump. The sensing and storage system can have a fluid removal line for the removal of fluid from the dialysate flow loop.Type: GrantFiled: September 12, 2017Date of Patent: February 5, 2019Assignee: Medtronic, Inc.Inventors: Thomas E. Meyer, William P. Hajko, Thomas P. Hartranft
