RT info:eu-repo/semantics/article T1 An assessment of the suitability of a Liebau pump in biomedical applications A1 Anatol Hernández, Joaquín A1 García-Díaz, Manuel A1 Barrios Collado, César A1 Moneo-Fernández, José Ángel A1 Rubio, Manuel A1 Castro Ruiz, Francisco A1 Sierra Pallarés, José Benito K1 Mecánica de Fluidos K1 Wave mechanics, Fluid flows, Biofluids K1 2204.04 Mecánica de Fluidos AB Impedance pumping and asymmetric pumping are the main mechanisms of the Liebau effect, a type of valveless pumping. The primary objective of this study is to enhance the current understanding of the mechanics and functionality of a Liebau pump. To achieve this, a prototype pump is constructed, incorporating several novel features: a pinch frequency control system to optimize pump performance, a planar actuator developed using soft robotic technology, and a compliant chamber designed to mitigate flow fluctuations and prevent reverse flow, a common feature of this pumping method. Experimental tests conducted with this prototype demonstrate that the Liebau pump holds potential as a viable technology for fluid pumping in biomedical applications, especially when pulsatile flow is essential or when hemolysis needs to be minimized.
