Method and system for collecting leukoreduced red blood cells

A method and system for collecting leukoreduced red blood cells employing a spinning membrane separator including a housing having an upper end region and a lower end region in an operating position with a red blood cell outlet in the upper end region of the housing and a whole blood inlet in the lower end region of the housing. The method and system provide for flowing additive solution into the whole blood inlet of the housing to prime the separator; flowing whole blood into the whole blood inlet of the housing; separating red blood cells from the whole blood; flowing separated red blood cells out of the red blood cell outlet of the housing; combining the separated red blood cells with additive solution: passing the separated red blood cells and additive solution combination through a leukoreduction filter; and collecting the filtered red blood cells and additive solution.

BLOOD TREATMENT SYSTEMS AND METHODS

The present invention generally relates to hemodialysis and similar dialysis systems, including a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. One aspect of the invention is generally directed to new fluid circuits for fluid flow. According to one aspect, a blood pump is configured to pump blood to a dialyzer of a hemodialysis apparatus, the blood pump comprising a pneumatically actuated or controlled reciprocating diaphragm pump. In an embodiment, the diaphragm of the pump comprises a flexible membrane formed or molded to generally conform to a curved inner wall of a pumping chamber or control chamber of the pump, wherein the diaphragm is pre-formed or molded to have a control side taking a convex shape, so that any elastic tension on the diaphragm is minimized when fully extended into a control chamber of the pump. In another aspect, a system for monitoring the adequacy of blood flow in a blood line of the hemodialysis apparatus allows a controller to suspend dialysate pumping operations if the adequacy of blood flow in the blood line is sub-optimal, and to present information on a display on the quality of blood flow in the blood line.

Methods and Systems for Detecting an Occlusion in a Blood Circuit of a Dialysis System
20170258975 · 2017-09-14 ·

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.

Systems and methods for performing hemodialysis

Systems and methods for performing hemodialysis to remove metabolic waste from the blood of a patient are disclosed. The systems and methods preferably comprise at least one blood processing apparatus that receives whole blood from a patient.
