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.

主权项

1. A method of connecting a disposable cartridge and tubing set to a dialysis system, comprising the steps of:
positioning alignment features of the disposable cartridge and tubing set adjacent to alignment features of the dialysis system; mounting the disposable cartridge and tubing set onto the dialysis system to:
acoustically couple a venous drip chamber of the disposable cartridge and tubing set with one or more fluid level sensors of the dialysis system, andengage a cartridge presence detector of the dialysis system, the cartridge presence detector configured to initiate automatic loading of a blood pump portion of the cartridge and tubing set into a blood pump of the dialysis system.
