Abstract

An oxygen adapter for delivering low volume supplemental oxygen to a tracheostomized patient using a conventional tracheostomy speaking valve is provided, the adapter including a tube fitting for receiving conventional tubing thereon, and an outlet section attached to the tube fitting and defining a channel communicating between the tube fitting and an outlet end of the outlet section. The outlet section preferably extends axially from the tube fitting along the outer wall of a speaking valve to which the adapter is connected, the outlet end being located adjacent an inlet of the speaking valve, thereby delivering oxygen from the tubing received on the tube fitting to the inlet of the speaking valve. The adapter may be detachably connectable to the cylindrical wall of the speaking valve, preferably by a pair of semi-rigid gripping flanges adapted to peripherally engage the cylindrical wall of the speaking valve. The adapter preferably comprises injection-molded plastic, such as polycarbonate.

11. The adapter of claim 10, wherein said gripping flanges comprise a semi-rigid material, thereby allowing said gripping flanges to resiliently open to detachably connect said adapter to the speaking valve.

12. The adapter of claim 1, where said tube fitting extends substantially radially from the outer wall when said adapter is connected to the speaking valve.

13. The adapter of claim 1, wherein said adapter comprises injection-molded plastic.

14. An adapter for detachably connecting tubing to a tracheostomy speaking valve having an outer wall and an inlet end, said adapter comprising:

a gripping member adapted to connect said adapter to the outer wall of the speaking valve;

a tube fitting adapted to receive tubing thereon, said tube fitting having a passage therein adapted to communicate with tubing received thereon, said tube fitting extending substantially radially from the outer wall of the speaking valve when said adapter is connected to the speaking valve; and

a channel section attached to and extending substantially perpendicularly from said tube fitting, said channel section comprising a plurality of walls defining a channel communicating between said passage and an outlet end of said channel section, said outlet end being adapted to be located adjacent the inlet end of the speaking valve when said adapter is connected to the speaking valve.

15. An adapter for delivering supplemental oxygen to a tracheostomized patient using a speaking valve, the speaking valve having a cylindrical outer wall and an inlet end, said adapter comprising:

a port having a base and an outer end, and having a passage extending between said base and said outer end, said outer end being attachable to a source of supplemental oxygen, said port extending substantially radially from the cylindrical outer wall of the speaking valve when said adapter is connected to the speaking valve;

a pair of semi-rigid gripping flanges attached to said base of said port, and being adapted to peripherally engage the cylindrical outer wall of the speaking valve, thereby detachably connecting said adapter to the speaking valve; and

an outlet section attached to said port, said outlet section including a plurality of walls defining a channel, said channel communicating between said passage and an outlet end of said outlet section, said outlet end being located adjacent the inlet end of the speaking valve when said adapter is connected to the speaking valve, thereby delivering oxygen from the source attached to said port to the inlet end of the speaking valve.

16. The adapter of claim 15, wherein said outlet section substantially abuts and extends axially along the cylindrical outer wall when said adapter is connected to the speaking valve.

17. The adapter of claim 15, wherein said plurality of walls comprise a top wall and two side walls, said side walls substantially engaging the outer wall of the speaking valve, the outer wall defining a bottom wall of said channel, thereby allowing oxygen to travel through said channel.
