    Abstract: A pumping system comprising: a pneumatically driven diaphragm pump comprising: a rigid chamber wall; a rigid limit structure; a flexible diaphragm attached to the rigid chamber wall and interposed between the rigid chamber wall and the rigid limit structure, such that the flexible diaphragm and rigid chamber wall together define a pumping chamber and the flexible diaphragm and the rigid limit structure together define an actuation chamber; an inlet in the rigid chamber wall for allowing liquid to enter the pumping chamber; and an outlet in the rigid chamber wall for allowing liquid to exit the pumping chamber; an actuation system that alternately provides either a positive or a negative pressure to the actuation chamber; wherein the actuation system includes: a first reservoir held at a positive pressure; a second reservoir held at a negative pressure; a valving mechanism selectively connecting the actuation chamber to one of the first and second reservoirs to control a pressure in the actuation chamber; and an actuation chamber pressure transducer for measuring a pressure of the actuation chamber; and a controller that receives pressure information from the actuation chamber pressure transducer and in a first time period controls the valving mechanism to complete at least one full stroke of the flexible diaphragm by moving the flexible diaphragm between a position touching the rigid limit structure and a position touching the rigid chamber wall, the controller being configured to record a full stroke value for a stroke parameter corresponding to each at least one full stroke, and in a subsequent time period to control the valving mechanism to complete partial strokes of the flexible diaphragm by controlling the stroke parameter to be a fraction of the full stroke value.

    Abstract: The present invention relates to a blood treatment device, comprising a first hemofilter configured to increase a hemoconcentration of blood; a second hemofilter arranged fluidically downstream of the first hemofilter and configured to remove toxins from the blood into an albumin containing dialysate; a flow regulator arranged in a fluid line conducting fluid out of the first hemofilter; a flow sensor configured to measure a flow in a fluid line conducting dialysate into the second hemofilter and a flow in a fluid line conducting dialysate out of the second hemofilter; and a control unit configured to control the flow regulator depending on the measurement data of the flow sensor to set an outflow of dialysate out of the first hemofilter.

    Abstract: A bedside cell processing system including an apheresis system configured to collect from a patient a blood component comprising target cells, a cell processing system configured to receive the target cells from the apheresis system and to process the target cells, and a reinfusion system configured to receive the processed target cells and to return the processed cells to the patient. A method of operating a bedside cell processing system for a patient also is provided, including operating the apheresis system to collect from the patient via a collection flow path a blood component comprising target cells, operating a cell processing system to receive the target cells via a collected target cells flow path and to process the target cells, operating the reinfusion system to receive the processed target cells via a processed target cells flow path and to return the processed target cells to the patient.
