Abstract
Abstract 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.

Claim 1
Independent Claim
343 words
An oxygen insufflation device for wearing on the head of a person comprising a head engaging frame including a tubular front portion (2), a first tubular flexible link (5) connected to one side of said front portion, a second tubular flexible link connected to an opposite side of said front portion, a first tubular temple portion (6) having a first ear-engaging part (14) at one end thereof and connected to said first flexible link at an opposite end of said first tubular temple portion, a second tubular temple portion (6) having a second ear-engaging part (14) at one end thereof and connected to said second flexible link at an opposite end of said second temple portion, a tubular member (13) connected to said tubular front portion at a location intermediate of said one and said opposite side of said tubular front portion, said tubular member having a selected length and connected to said tubular front portion at one end thereof, a nose seat (11) connected to said tubular member at an opposite end thereof, said nose seat shaped to have opposite sides adapted for engaging the bridge of a person's nose, a flexible tubular nose connection (3) connected to one of said opposite sides of said nose seat, a hollow nose plug connected to said flexible tubular nose connection at an end of said flexible tubular nose connection remote from said nose seat, said flexible tubular nose connection having a length so that with the nose seat engaged on the bridge of a person, the nose plug is engaged in one nostril of the person, and a gas connection (7) connected to said first tubular temple portion for supplying breathing gas to said first tubular temple portion, through said first tubular flexible link, said tubular front portion, said tubular member and said flexible tubular nose connection to said hollow nose plug, said selected length of said tubular member being chosen to maintain said front portion above the eyes of a person when said nose seat is engaging the bridge of the person's nose.
Claim 2
Dependent Claim
343 words
An oxygen insufflation device for wearing on the head of a person comprising a head engaging frame including a tubular front portion (2), a first tubular flexible link (5) connected to one side of said front portion, a second tubular flexible link connected to an opposite side of said front portion, a first tubular temple portion (6) having a first ear-engaging part (14) at one end thereof and connected to said first flexible link at an opposite end of said first tubular temple portion, a second tubular temple portion (6) having a second ear-engaging part (14) at one end thereof and connected to said second flexible link at an opposite end of said second temple portion, a tubular member (13) connected to said tubular front portion at a location intermediate of said one and said opposite side of said tubular front portion, said tubular member having a selected length and connected to said tubular front portion at one end thereof, a nose seat (11) connected to said tubular member at an opposite end thereof, said nose seat shaped to have opposite sides adapted for engaging the bridge of a person's nose, a flexible tubular nose connection (3) connected to one of said opposite sides of said nose seat, a hollow nose plug connected to said flexible tubular nose connection at an end of said flexible tubular nose connection remote from said nose seat, said flexible tubular nose connection having a length so that with the nose seat engaged on the bridge of a person, the nose plug is engaged in one nostril of the person, and a gas connection (7) connected to said first tubular temple portion for supplying breathing gas to said first tubular temple portion, through said first tubular flexible link, said tubular front portion, said tubular member and said flexible tubular nose connection to said hollow nose plug, said selected length of said tubular member being chosen to maintain said front portion above the eyes of a person when said nose seat is engaging the bridge of the person's nose.
Claim 3
Dependent Claim
49 words
