Abstract:
1. A high flow volume nasal irrigation device, comprising: a) a squeeze bottle having an open end, a reservoir of a liquid and a volume of air, the squeeze bottle configured to elastically deform in response to a manual pressure from a user and thus pressurize the liquid and the air; b) a dip tube configured to convey a pressurized liquid flow from a first end inside the squeeze bottle to a second end outside the squeeze bottle, the second end comprising a void in a tube wall; c) a removable nipple cap disposed on the squeeze bottle open end, the removable nipple cap comprising a nipple orifice and a coaxially aligned cap socket configured to rotatably seal with the dip tube second end to form a conduit with the dip tube; and d) an air channel formed axially and adjacent to the cap socket, the air channel and the void configured to form an air metering orifice rotatably aligned to introduce a plurality of air pockets into the pressurized liquid flow from the volume of air and thus generate a pulsatile fluid flow.
