| Abstract: |
A head-mounted oxygen-administration device designed to improve the level of inspired oxygen concentration for mouth and nasal breathing users without interference with the user's activities of eating and talking and which includes a pair of nasal cannulas mounted on one side of a body having a chamber adapted for connection to a source of oxygen under pressure providing a positive oxygen flow into the chamber, and a flow discharge aperture provided on the opposite side of the body in communication with the chamber and functioning upon restriction of nasal inhalation and during oral inhalation to direct oxygen flow from the chamber to the user's mouth, such directed flow being effected from a position remote from the user's mouth.

What is claimed is:
1. A head-mounted oxygen-administration device comprising:
- passage means providing a chamber having a longitudinal dimension adapted to extend at least under the nose of a user and having an inlet adapted for connection to a source of oxygen under pressure providing a positive oxygen flow into said chamber;
- nasal cannula means mounted on said passage means at one side thereof and extending perpendicularly to said longitudinal dimension of said chamber and being in communication with said chamber and formed for insertion into the nares of the user and providing nasal oxygen induction upon nasal inhalation;
- means flow discharge aperture provided on said means directly opposite said nasal cannula means thereby being remote from the user's mouth and being in communication with said chamber and functioning upon restriction of nasal inhalation and during oral inhalation to direct oxygen flow from said chamber to the user's mouth head mounting means for securing said passage means to the head of a user whereby said nasal cannula means are positioned in each respective nostril.
