Abstract
A hemodiafiltration (HDF) system is provided for performing HDF treatment. The HDF system includes a mixing system for mixing nitric oxide (NO) with other chemicals to produce a dialysis fluid. The HDF system further includes an extracorporeal blood circuit that includes a filter for separating the dialysis fluid into a dialysate and NO spiked substitution fluid. The extracorporeal blood circuit also includes a dialyzer that receives the dialysate and a blood line connected to the dialyzer. The blood line includes admission points connected to the filter. The admission points are used to administer the NO spiked substitution fluid to the patient during the HDF treatment.
Claims15
A hemodiafiltration (HDF) system for performing HDF treatment, comprising:
- a mixing system, comprising:
- a nitric oxide dispenser configured to provide nitric oxide (NO) to a mixing chamber;
- a chemical dispenser configured to provide chemicals to the mixing chamber;
- and
- the mixing chamber configured to mix the NO and the chemicals to produce a dialysis fluid;
- an extracorporeal blood circuit, comprising:
- a filter configured to separate the dialysis fluid into a dialysate and NO spiked substitution fluid;
- a dialyzer configured to receive the dialysate from the filter;
- and
- a blood line connected to the dialyzer and comprising one or more admission points, wherein the one or more admission points are connected to the filter and the NO spiked substitution fluid is administered during the HDF treatment using the one or more admission points;
- and
- a controller configured to:
- provide instructions to the mixing system to produce the dialysis fluid comprising the NO;
- and
- provide instructions to the extracorporeal blood circuit to perform the HDF treatment using the dialysate and the NO spiked substitution fluid.
