ABSTRACT:

FIELD OF THE INVENTION
The invention is directed towards a device for facilitating respiration or breathing.
BACKGROUND OF THE INVENTION
The present device is of the type used to expand the air passages in nostrils. Such devices have been used in the past to improve breathing, eliminate or reduce snoring or as surgical aid among other things.
Devices which have been used in this regard include U.S. Pat. No. 1,709,740 issued Apr. 16, 1929 to Rogers. This reference shows the use of a nasal distender using a wire bridge between two u-shaped members which contact the inner walls of the nose.
In U.S. Pat. No. 1,950,839 issued Mar. 13, 1934 to Cherila discloses a dilator using a metal bridge between two suction members attached to the outside of the nostrils to pull them outward keeping the nostrils open.
With regard to U.S. Pat. No 3,710,799 issued Jan. 16, 1973 to Caballero, it discloses a pair of spherical cages for insertion into the nostrils which are joined by a chain. In U.S. Pat. No. 4,201,217 issued May 6, 1980 to Slater, there is disclosed a nostril enlarger having a u-shaped member having opposite posterior protuberances biased outwardly for positioning in the nostril cavity. A bridge therebetween is the opposite protuberances apart the proper distance.
U.S. Pat. No. 4,414,977 issued Nov. 15, 1983 to Rezakhany shows another variation of a nasal dilator. Lastly, U.S. Design Pat. No. 310,565 issued Sep. 11, 1990 to Petruson shows a device for insertion into the nose having two end portions having raised protuberances interconnected by a bridge.
While all of the foregoing devices have attendant advantages and disadvantages, there exist a need to provide for a nasal dilator which is relatively simple yet effective whilst allowing for the device to be tailored for the particular individual using it.
SUMMARY OF THE INVENTION
It is a principal object of the invention to provide for a nasal dilator which is relatively simple yet effective.
It is a further object of the invention to provide for a nasal dilator that can be readily adjusted so as to allow it to be tailored to a particular individual.
The present invention provides for a nasal dilator which is made of plastic or silicone and comprises opposite curved pads located at the ends of a resilient bar having a center member thereon. The dilator is flexible with the pads squeezed together for insertion into respective nostrils. The resilient bar and centering member then biases the pad outward so as to dilate the anterior section of the nasal cavity. Included on the centering member are a series of notches one or more of which can be cut so as to reduce the biasing nature of the centering member thereby allowing the force of the device to be adjusted for varying needs of the individual.
