High Flow Volume Nasal Irrigation Device and Method for Alternating Pulsatile and Continuous Fluid Flow

A high flow volume nasal irrigation device, comprising:

• a) a squeeze bottle having an open end, a reservoir of liquid and a volume of air, the bottle configured to elastically deform in response to a manual pressure from a user and thus pressurize the liquid and 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 the tube wall;
• c) a removable nipple cap disposed on the squeeze bottle open end, the cap comprising a nipple orifice and a coaxially aligned cylindrical socket configured to rotatably seal with the dip tube second end to form a conduit with the 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 when rotatably aligned to introduce a plurality of air pockets into the fluid flow from the air volume and thus generate a pulsatile fluid flow.

• 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 dip tube first end configured to extend into the reservoir of liquid;
• c) a removable cap disposed on the squeeze bottle open end, the cap comprising a nipple end and an opposing coaxial extension, the extension configured to seal to the tube and comprise an externally threaded channel, the nipple end comprising a tube stop and an orifice;
• and
• d) an air metering orifice formed at a mouth of the externally threaded channel in a hollow area above the tube stop accessible to the volume of air to introduce a plurality of air pockets into the fluid flow and thus generate a pulsatile fluid flow.
