ABSTRACT:
A high flow volume nasal irrigation device for alternating pulsatile and continuous fluid flow includes a segmented dip tube with a free end extending inside a squeeze bottle configured to convey a liquid under an elevated chamber pressure from a reservoir therein to a lower pressure outside the bottle. The device also includes an elastic segment at the free end of the tube configured to oscillate about a bending in the segment in response to a differential pressure between an internal pressure and the chamber pressure, the segment having an elastic restoring force in opposition to the bending. The disclosed device further includes a pulsatile portion of the elastic segment configured to close at the segment bending and to reopen under the elastic restoring force and to thus generate a periodic pulsatile fluid flow through the tube with a period corresponding to the elastic segment oscillation.
