A 1-litre analogue medical oxygen system

Ambulatory medical oxygen for COPD patients

Gm Design Development worked as the product development team to design the ambulatory oxygen system, along side Luxfer Gas Cylinders and Southampton University, who undertook user trials.

The solution

The Gm Design Development team designed the oxygen system so it was much more user friendly than existing systems on the market. We improved the ergonomics with easy grip dials to adjust the flow because many users have dexterity problems. A large, easy-to-read gauge was incorporated so users had greater confidence in how much oxygen remained in the cylinder.

We improved the appearance, away from an industrial cylinder product to a clean, modern looking consumer-health product, helping to reduce the stigma users often found using current systems.

We helped Luxfer develop the brass valve assembly - critical in a 300bar system. The system and case mouldings also needed to be compatible with the customers existing filling lines.

  • MEDICAL OXYGEN – SYSTEM ASSEMBLY

    The medical oxygen case mouldings fit around the valve assembly, protecting it from damage. The ergonomic form allows users to handle it easily.

  • MEDICAL OXYGEN – ERGONOMIC CONTROLS

    An ergonomically designed shut-off dial allows the oxygen to be switched off easily by the user. A tamper-evidence feature was also incorporated.

  • MEDICAL OXYGEN – FLOW SETTING CONTROLS

    An ergonomic flow dial was designed for ease of use by users with poor grip and dexterity. A maximum flow setting feature was designed into the collar.

  • MEDICAL OXYGEN – CANNULA CONNECTION

    A quick-push-fit fir-tree cannula connection is incorporated into the valve and protected by the case mouldings and elastomer fir-tree cover.
