摘要:
An oxygen insufflation device for wearing on the head of a person comprises a head engaging frame similar to a spectacle frame including a front portion and a side temple portion engaged on each side of said frame terminating in respective ear engaging ends. The front member is engaged with the front portion of the frame and has a nose feed engageable over the person's nose and a downwardly extending portion terminating in a nose plug which is engageable into a single nostril. A flexible connection for supplying oxygen is connected into the frame at one of the temple portions and an oxygen flow passage is defined from this flexible connection through the associated temple portion and along the front of the frame and down said front member in the downwardly extending portion and terminates in a discharge opening in the nose plug. The frame advantageously includes a flexible connection between the front portion of the frame and the temples in the form of flexible links which are made from corrugated tube stock. Ear engaging portions comprise bows which are made of helically wound flat wires enclising a spring construction within the wires. The front portion of the device advantageously includes a flexible angular tubular member terminating in the nose seat.
