Abstract: A device for administering oxygen to infants during nursing which provides an oxygen flow-directing member, in half-funnel shape, which includes an inlet opening for connection to oxygen-supplying tubing, an internal plate with a plurality of holes for oxygen flow regulation, and a semicircular outlet. The flow-directing member is attached to the nursing source in two configurations, a bottle feeding configuration and a breast feeding configuration. In the bottle feeding configuration, the flow-directing member is attached to the neck of the feeding bottle by a partial neck-encircling foam collar with adhesive tabs. In this configuration, the flow-directing member may rotate about a pair of rivet-like fasteners connected to the foam collar, so as to pivot forwards and backwards on the bottle, for adjustably directing the oxygen flow directing upon the nursing infant's nostrils.
