Abstract

The invention relates to a nasal cannula for an anti-snoring apparatus, comprising a forked tube pneumatically connected to apertures, which are embodied and positioned in such a way that air can be administered into the nose of a user via these apertures. The nasal cannula further comprises a heating wire extending in the interior of forked tube in such a way that the heating wire can heat the air supplied through the forked tube. The invention moreover relates to a nosepiece and to a Y-shaped element for nasal cannula including internal radius steps at tube connection points. The invention further relates to a nosepiece and to a Y-shaped element having rounded off transition regions. The invention finally relates to a method for avoiding condensation in nasal cannulas. To this end, the gas is heated as it flows through the tubes of a nasal cannula.
