1. A hybrid hemodialysis (“
- HD”
)/peritoneal dialysis (“
PD”
) system comprising;
a reservoir;
a weigh scale operably coupled with the reservoir;
at least one controller programmed to run (i) an HD treatment in which blood is pumped to a blood compartment of a dialyzer, fresh HD dialysis fluid is pumped to a dialysis fluid compartment of the dialyzer, and used HD dialysis fluid is pumped from the dialysis fluid compartment of the dialyzer to the reservoir, and at a different time (ii) a PD treatment in which fresh PD dialysis fluid is pumped to a patient and used PD dialysis fluid is pumped from the patient to the reservoir;
a dialysis fluid pumping unit fluidly connected to the reservoir;
an HD cassette configured for connection to the dialysis fluid pumping unit to run at least the fresh and used HD dialysis fluid portion of (i); and
a PD cassette configured for connection to the dialysis fluid pumping unit to run (ii), the PD cassette being interchangeable with the HD cassette for connection to the dialysis fluid pumping unit.

Abstract
A hybrid hemodialysis (“HD”)/peritoneal dialysis (“PD”) system includes: a reservoir; a weigh scale operably coupled with the reservoir; and at least one controller programmed to run (i) an HD treatment in which blood is pumped to a blood compartment of a dialyzer, fresh HD dialysis fluid is pumped to a dialysis fluid compartment of the dialyzer, and used HD dialysis fluid is pumped from the dialysis fluid compartment of the dialyzer to the reservoir, and at a different time (ii) a PD treatment in which fresh PD dialysis fluid is pumped to a patient and used PD dialysis fluid is pumped from the patient to the reservoir.
