Patent number: 10960120Abstract: A dialysis machine which monitors the pressure of blood entering and leaving a patient's body using several sensors (37, 39) and adapts the pressure of a dialysate solution feed to compensate for compliances in the dialysate fluid flow path. As a consequence, better flow balance is maintained throughout dialysis treatment leading to a more uniform removal of waste materials from the blood.Type: GrantFiled: January 28, 2013Date of Patent: March 30, 2021Assignee: QUANTA DIALYSIS TECHNOLOGIES LIMITEDInventors: Mark Wallace, Ben Higgitt

Patent number: 9833553Abstract: A hemodialysis machine comprising a dialysate flow path for delivering a flow of dialysate solution through a dialyser, the flow path including a flow balancer for achieving a balance in the dialysate solution flow volume observed between an inlet and an outlet of the dialyser over the course of a treatment, the flow balancer comprising a first flow balance pump having an inlet valve and an outlet valve and a second flow balance pump having an inlet valve and an outlet valve, wherein the flow path further includes a flow restrictor means downstream of the flow balance pumps to reduce the pressure difference across the valves in the dialysate flow path.Type: GrantFiled: February 16, 2012Date of Patent: December 5, 2017Assignee: Quanta Fluid Solutions Ltd.Inventors: Ben Higgitt, Mark Wallace, Jeremy Harrop

Publication number: 20150027951Abstract: The invention relates to a dialysis machine having improved flow balance. In particular, the invention monitors the pressure of blood entering and leaving a patient's body using several sensors (37, 39) and adapts the pressure of a dialysate solution feed to the dialysis machine to compensate for compliances in the fluid flow path. As a consequence, better flow balance is maintained throughout dialysis treatment leading to a more uniform removal of waste materials form the blood.Type: ApplicationFiled: January 28, 2013Publication date: January 29, 2015Inventors: Mark Wallace, Ben Higgitt
