A DEVICE FOR IMPROVING AIR FLOW THROUGH A NASAL CAVITY DURING PHYSICAL ACTIVITY SUCH AS SPORTING PURSUITS

摘要

A device for improving flow of air through a nasal cavity of a wearer during activity such as cycling or running or like exercise substantially minimizing air flow resistance, the device including a substantially U-shaped body forming a bridge for spanning adjacent nasal cavities of a wearer; a first adjustable body and a second adjustable body mounted to opposite upright portions of the U-shaped body, the first and second bodies each having: a belt adjustable about an attachment mount on an upright portion of the U-shaped body; a rib extending outwardly and arcuately from a portion of the U-shaped body distal to the bridge, the each rib ending in a relatively large surface area portion connected to a portion of the belt, the large surface area portion of the each rib adapted for abutting internal wall surfaces of the nasal cavity of a wearer, and wherein the belt and rib form an open channel defining an air flow pathway within the nasal cavity; and whereby in an operating condition the belt or belts is tightened by a wearer to allow insertion, and thereafter loosened so as to urge the large surface area portion of the ribs against nasal cavity walls, whereby resistance to flow of air is substantially reduced, producing improved air flow capacity for sporting activities and the like.
