Dialysis system including flow path insulator

Abstract

A renal failure treatment system (10), comprising: a dialyzer (102); a blood circuit (100), including a blood pump (120), in fluid communication with the dialyzer (102); a dialysis circuit (30), connected to the said dialyzer (102) in fluid communication; and at least one flow path insulator (150, 155), located in said dialysis circuit (30) or said blood circuit (100), said flow path insulator (150, 155) comprising A structure that divides the liquid flowing in the flow path insulator (150, 155) into a plurality (for example, two or more) of separated liquid segments (160), the plurality of separated liquid segments (160) in Electrical isolation is formed within the flow path insulator (150, 155).

Description

technical field [0001] The present disclosure generally relates to medical devices. More specifically, the present disclosure relates to electrical insulation of medical devices. Background technique [0002] Hemodialysis ("HD") typically uses diffusion to remove waste products from a patient's blood. Diffusion is caused by a diffusion gradient that occurs across a semipermeable dialyzer between blood and an electrolyte solution called dialysate. Hemofiltration ("HF") is another renal replacement therapy that relies on the convective transport of toxins from the patient's blood. This therapy is achieved by adding replacement fluid (typically 10 to 90 liters of such fluid) to the extracorporeal circuit during treatment. During HF therapy, the patient's accumulated replacement fluid and fluids between treatments are ultrafiltered, thereby providing a convective delivery mechanism, which is particularly beneficial for the removal of medium and large molecules (in hemodialysi...
