Abstract:
1. A method for regulating fluid pump pressures at a distal end of a solution line in a peritoneal dialysis system, the peritoneal dialysis system comprising a fluid flow control apparatus having a membrane-based pump fluidly connected to the solution line, the method comprising: establishing a desired pressure limit for fluid pressure at the distal end of the solution line; determining a static pressure in the fluid flow control apparatus; establishing fluid communication between the fluid flow control apparatus and the solution line; determining a static pressure at the distal end of the solution line; calculating a pressure to be applied to a membrane-based fluid pump based on a pressure differential between a static pressure at the distal end of the solution line and a static pressure in the fluid flow control apparatus; and applying the pressure to the membrane-based pump to achieve a pressure at the distal end of the solution line that does not exceed the desired pressure limit.
