More Information
Summary:The invention discloses a passive pulsation fluid filtering device, which comprises an upper substrate, a lower substrate and a thin film layer, wherein the thin film layer is arranged between the upper substrate and the lower substrate; the upper substrate, the lower substrate and the thin film layer are in sealing fit; the bottom of the upper substrate is laterally provided with a micro-channel used for fluid to flow; two ends of the micro-channel are respectively provided with an inlet from which the fluid flows in, and an outlet from which the fluid flows out; the lower substrate is longitudinally provided with a through hole. According to the passive pulsation fluid filtering device disclosed by the invention, the outlet flowing rate of the fluid can be fluctuated within a smaller range so as to achieve a purpose of filtering.
