DIALYSIS SYSTEM AND METHODS

摘要

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.

1. A method of achieving dynamic balancing with a dialysis system, comprising:
operating a blood pump to move a flow of blood from a patient through a patient tubing set and a blood-side of a dialyzer; operating a first dialysate pump and a second dialysate pump to move a flow of dialysate through a dialysate-side of the dialyzer; bypassing the flow of dialysate through the dialysate-side of the dialyzer; and while the flow of dialysate through the dialysate-side of the dialyzer is bypassed, measuring a dialysate pressure between the first dialysate pump and the second dialysate pump, and adjusting a pump speed of the second dialysate pump until the measured dialysate pressure stabilizes.
