Abstract

A retention device and method for retaining a gas delivery system provide improved safety and comfort for the recipient of oxygen or other gaseous mixture. The retention device includes a tube holder for maintaining a tension on a supply tube of a gas delivery system and an ear stop for transferring the tension of the supply tube to the back of an ear of the recipient. The device is generally molded from a flexible plastic material and includes a tube holder portion defining a cylindrical cavity therethrough for receiving and applying tension to a supply tube and an ear stop portion extending downwards from and end of said tube holder portion so that the tube holder portion may be placed over the recipient's ear and the ear stop placed behind the recipient's ear. A pair of the retention devices will generally be used, one for each ear. A channel or diverter may be included on the top of the tube holder portion to permit recipients wearing eyeglasses to comfortably use the device and the tube holder portion may extend backward from the ear stop to produce a cantilever effect that more effectively retains the ear stop against the recipient's ear. A radial opening may be provided in the tube holder portion for insertion of a supply tube where an end of the supply tube is not available. The opening may be closed and secured by forming mating surfaces in the walls defining the opening, by a flap to wrap around the opening or by other securing means.
