Claim of US Patent No. 11,116,067


1. A renal failure therapy system comprising:a dialyzer;
a blood circuit in fluid communication with the dialyzer;
a dialysis fluid circuit in fluid communication with the dialyzer; and
an electrically floating fluid pathway comprising at least a portion of the blood circuit and at least a portion of the dialysis fluid circuit, wherein the only electrical path to ground is via used dialysis fluid traveling through the renal failure therapy system to earth ground,
wherein at least one electrical component in the at least a portion of the dialysis fluid circuit of the electrically floating fluid pathway is electrically bypassed, and
wherein the at least a portion of the dialysis fluid circuit includes at least a portion of a fresh dialysis fluid line and at least a portion of a used dialysis fluid line.
