Abstract
A non-linear flow restrictor that limits the maximum flowrate in a medical aspiration system. The flow restrictor changes the direction of fluid flow to generate non-linear effects in the fluid. This creates a non-linear relationship between the pressure within the system and the flowrate of the fluid. The non-linear relationship may define a pressure versus flowrate curve that has a flat portion where the flowrate does not increase with an increase in pressure.
