DIALYSIS SYSTEM AND METHODS
First Claim
1. A method of priming a tubing set and a dialyzer of a dialysis system, comprising the steps of:
- operating a blood pump of the dialysis system in a first operating mode to move saline from a saline source into the tubing set and through a blood-side of the dialyzer in a first direction to remove air from the tubing set and the blood-side of the dialyzer; and
operating the blood pump in a second operating mode to move at least a portion of the saline through the blood-side of the dialyzer in a second direction opposite to the first direction.

Abstract
Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy. For example, the dialysis systems include disposable cartridge and patient tubing sets that are easily installed on the dialysis system and automatically align the tubing set, sensors, venous drip chamber, and other features with the corresponding components on the dialysis system. Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.
