The present specification discloses a portable dialysis system comprising a mechanism that allows the user to accurately position an air bubble in a venous line, so that it can be safely removed. When an air bubble is detected, the system automatically runs the blood pump in a direction such that the air bubble is placed close to the extraction point on the venous line, from where it can safely be removed using a needleless syringe.

The present specification describes a modular, portable hemofiltration system, for providing improved clearance levels of blood toxins, which includes at least one roller pump that is designed and operated to generate a rapidly varying pressure profile of fluid within at least a blood circuit of the hemofiltration system.

Methods and systems of generating rapidly varying pressure amplitudes in fluidic circuits in a dialysis treatment system

The present specification describes systems and methods for detecting an occlusion in a tubing carrying a patient's blood through a manifold and into a dialyzer in a dialysis system. A controller measures pressures value of the blood at a predetermined point after exiting the manifold and before entering the dialyzer, calculates a historical running average, calculates a weighted sum of the most recent pressure values, and determines whether to trigger an occlusion alarm based on a function of the historical running average and the weighted sum of the most recent pressure values.

The present specification provides a reservoir bag for containing a dialysate during a dialysis treatment. The bag has four walls and a membrane extending from a first wall to a second opposing wall which divides the bag into a first and a second sub-reservoir having changeable volumes. The maximum volume of each sub-reservoir is between 80 to 100% of the entire volume of the bag. The bag further includes at least an inlet and an outlet positioned in at least one of the walls for enabling fluid entry into and exit out of the first sub-reservoir and at least an inlet and an outlet positioned in at least one of the walls for enabling fluid entry into and exit out of the second sub-reservoir.
