SUPPLEMENTAL OXYGEN ADAPTER FOR TRACHEOSTOMY SPEAKING VALVES

摘要

An oxygen adapter (10) for delivering low volume supplemental oxygen to a tracheostomized patient using a conventional speaking valve (110), is provided. The adapter comprises a tube fitting for receiving conventional tubing thereon, an outlet section attached to the tube fitting 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 connectible 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 comprises injection molded plastic such as polycarbonate.
