Abstract
A pulsation attenuator for a fluidic system with a fluidic pump. The pulsation attenuator includes a fluidic channel, a first fluidic device adapted to attenuate pulsations, and a second fluidic device adapted to attenuate pulsations. Preferably, the first fluidic device includes a first fluidic resistor and a first fluidic capacitor, and the second fluidic device includes a second fluidic resistor and a second fluidic capacitor. Preferably, the first fluidic resistor and second fluidic resistor are resistive channels. Preferably, the first fluidic capacitor and second fluidic capacitor include a membrane that expands and accumulates fluid and then contracts and reintroduces the accumulated fluid into the fluidic channel.
