An adapter for breathing-oxygen cylinders uses tank-air pressure to lock the regulator in place. The simple adapter is easy to use, fits any regulator, and is up to 30-times stronger than standard screw-yolk mechanisms. The adaptor slides onto the tank, and once the oxygen is turned on, self-locks until the user presses a release button to take it off. The design preserves the simplicity and function of the screw yoke and lowers manufacturing costs.

Developer Andrew Douglas of WEL Innovation Inc., London, Ontario, Canada, (welinnovations.com) was looking for an easier way to connect an oxygen regulator to a cylinder. After spending time with patients, Douglas noticed the common screw-yoke attachment on regulators was the focus of many complaints. Most seniors couldn't remove regulators on their own. In addition, the senior's inability to change their tanks was a major service issue for oxygen suppliers.

One full-time service rep estimated spending 60% of his day changing oxygen cylinder for seniors. Even hospital personnel suffered physical strains due to the increased number of patients who require oxygen therapy.

The adaptor cuts the time spent changing oxygen tanks in half and there is no great strength required. Douglas suggests the adapter might work best if built into existing regulators because adding another component isn't ideal.
