| Abstract: |
An apparatus for administration of a gas to a human and the exhausting thereof including a gas flow control connected to one end of a gas administering device which has on the other end protrusions for sealing engagement with nostrils of the nose. A gas supply conduit is connected to the gas flow control and a gas exhaust conduit is connected to the gas flow control, the gas flow control causes an intake of gas through the supply conduit and said gas administering device and out said protrusions thereon upon inhalation of a user of the apparatus. The gas flow control causes the exhausting of exhaust gas from said gas administering device through said gas flow control and out said gas exhaust conduit to a gas collector upon expiration of the user of the apparatus.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. A gas flow control for use in combination with a gas administering device, said flow control comprising:
- (a) a fixed body,
- (b) said body member having an intake conduit terminating in,
- (c) a single exhaust conduit separate from said intake conduit and joining said intake conduit in V-formation,
- (d) a central conduit formed in said body and intersecting the apex of the V-formation of said intake conduit and said single exhaust conduit,
- (e) means for attaching a gas supply line to said intake conduit, and
- (f) means for attaching an exhaust gas line to said exhaust conduit,
- (g) gas administering means connected to said central conduit whereby during inspiration by a user the flow of intake fresh gas is through said intake conduit and said central conduit in one direction and upon expiration patient exhaust gases flow through said central conduit in the opposite direction and out through said single exhaust conduit,
- (h) said exhaust conduit having manually operable means located therein for occluding the flow of fresh intake gases therethrough whereby the flow of fresh intake gases through said intake conduit are blocked from entering said exhaust conduit and directed to enter said central conduit at said V-formation to allow forced inspiration of fresh intake gases through said intake conduit.
