Dialysis system and methods

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.

Problems solved by technology

Many patients receive dialysis treatment at a dialysis center, which can place a demanding, restrictive and tiring schedule on a patient.

Moreover, in-center patients must follow an uncompromising schedule as a typical center treats three to five shifts of patients in the course of a day.

As a result, many people who dialyze three times a week complain of feeling exhausted for at least a few hours after a session.

The inefficiencies of most dialysis systems and the need for significant technician involvement in the process make it even more difficult for patients to receive dialysis therapy aw...
