The Invacare Aero-tech Uno is a single valve air cushion which is specifically designed for those considered to be at'Very High Risk' of developing pressure ulcers. Individual interconnected air cells allow free movement of air within the cushion, which allows the level of air to be individually adjusted to body shape thus maximising immersion. This air fluidised movement minimises changes in peak pressures, therefore providing excellent protection against pressure damage. The natural rubber material and vulcanised bonded base, offers excellent product longevity and may be suitable for those who experience allergic reactions to latex*.
