Filed:

Nov 6, 2010

Appl. No.:

12/941056

Inventors:

Mark Carpenter - White Lake MI, US

Assignee:

Skylab Developments Inc. - White Lake MI

International Classification:

A61M 31/00
A61M 1/00
B05B 1/08
F15C 1/08

US Classification:

604516, 604 34, 137826, 2391021

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.

International Classification:

A61M 5/178

US Classification:

604212, 604257, 604275, 604514, 222213, 222491, 222494

Abstract:

A high flow volume nasal irrigation device for alternating pulsatile and continuous fluid flow includes a tube comprising a free end and a housing at a second end adjoined to a cap with a coaxial cap nipple. A valve assembly inside the housing comprises a disk-like valve and a plurality of housing standoffs configured to stop the valve but allow a fluid flow in the housing and out the nipple. A cylindrical elastic valve seat is adjoined to the cap nipple and forms a gap with the valve on the standoffs. A spring opposes the valve moving toward the valve seat from the standoffs and assists in returning the valve from the seat to the standoffs and thus with the valve seat creates a periodic pulsatile fluid flow in the nipple in response to a chamber pressure which exceeds a critical chamber pressure threshold.

Inventors:

Mark Carpenter - White Lake MI, US

International Classification:

A61M 3/02

US Classification:

604257

Abstract:

A high flow volume nasal irrigation device includes a squeeze bottle, a reservoir of liquid and a volume of air. The bottle is configured to elastically deform in response to a manual pressure from a user and thus pressurize the liquid and air. The device also includes a dip tube configured to convey a pressurized liquid flow from a first end inside the bottle to a second outside end at a lower pressure. A removable nipple cap comprises an orifice and a coaxially aligned extension configured to seal with the dip tube and to form a conduit with the tube. At least one air metering orifice is formed in the fluid conduit accessible to the to volume of air. The air metering orifice is configured to introduce a plurality of air pockets from the air volume into the liquid flow and thus generate a pulsatile fluid flow in the conduit.
