ABSTRACT:
Tubular elements inserted for enhanced breathing into the nasal passages of a wearer to increase air flow include a bridge coupling between the elements of a spring-like rigidity to spread the elements towards their quiescent obtuse angle spread before insertion, supplemented by the stretching action afforded by a strap wrapped from opposing outside surfaces of the tubular elements around the wearer's head for added securement in an adjustable fit.
