Benefits of technology

Enables oxygen-dependent users to move freely and comfortably over a large distance from a heavy air canister without the tubing being dislodged, providing a reliable and constant oxygen supply.

Problems solved by technology

While such a system accomplishes it intended purpose, it has not proven to be entirely satisfactory as such a small lightweight canister can only supply a limited amount of oxygen enriched air.
Moreover, even though the canister is small and lightweight for many elders even such a lightweight canister is too heavy to be carried while performing ordinary tasks.

Embodiment Construction

[0021] Referring now to the drawings and more particularly to FIGS. 1-4, thereof there is illustrated a portable air delivery system 10, which is constructed in accordance to one preferred embodiment of the present invention. The portable air delivery system 10 is lightweight and can be easily carried or transported with a user thereby allowing an oxygen dependent user to freely move in any desired direction relative to a heavy and burdensome canister of air 11.

[0022] Considering now the portable air supply system 10 in greater detail with reference to FIGS. 1-4, the air delivery system 10 includes a coupling mechanism or an oxygen air tube reel assembly 12 having a stationary tube coupler 18 and an extendible length of oxygen tubing 14 that can be paid out or taken up over a predetermined length to give a user a wide range of mobility. The coupling mechanism 12 is adapted to be connected between a source of oxygen-enriched air, such as the air canister 11 and an air cannula 16 tha...

Abstract

An air delivery system includes a coupling mechanism that is adapted to be connected between a source of oxygen-enriched air and an air cannula that can be worn by a user. The coupling mechanism includes a spool assembly for paying out and for winding up a predetermined length of tubing coupled between the air cannula and the source of oxygen-enriched air. The spool assembly has a sufficiently low drag factor to allow complete mobility of a user wearing the cannula without causing it to be dislodged during pay out of the predetermined length of tubing and without causing it to be dislodged during take up of the predetermined length of tubing.

Description

FIELD OF THE INVENTION [0001] The present invention pertains to an air delivery system and more particularly to a coupling device between an air canister and an air cannula to provide an oxygen dependent user with extensive mobility from the air canister. BACKGROUND OF THE INVENTION [0002] Patients that require a constant supply of oxygen-enriched air are generally confined to an immediate area of the source of such oxygen-enriched air regardless of whether the source is a hospital air supply system or a simple portable air canister system. [0003] Therefore it would be highly desirable to have a new and improved air supply system that provides ambulatory patients with extensive mobility from their source of oxygen-enriched air whether the source is a hospital air supply system or an air canister system. [0004] One attempt at providing an oxygen dependent user with extensive mobility has been to provide a small lightweight canister that can be easily transported or carried by the use...
