Abstract
A dialysis system with post dialysis aseptic blood return including a fluid source, a dialyzer, a pump, a venous line, an arterial line, a bridge line coupled between the venous line and the arterial line, and a fluid source line coupled between the fluid source and a fluid port of the arterial line downstream for the bridge line. Aseptic blood return after dialysis is performed by blocking the arterial line between the bridge line and the fluid port, unblocking the bridge line, unblocking the fluid source line, and operating the pump in a forward direction to produce fluid flow from the fluid source, through the dialyzer, and through the bridge line to force venous blood in the venous line toward the patient venous access and arterial blood in the arterial line toward the patient arterial access.
