The current LifeChoice Activox Portable Oxygen Concentrator (Generator) is used on a prescriptive basis by patients who are diagnosed as requiring supplemental oxygen. The oxygen concentrator provides supplemental, high concentration oxygen to these patients. It is not life-supporting nor life-sustaining. It may be used continuously in a home, institution or travel environment. The LifeChoice Activox is also portable.
A stationary mains electricity (AC-powered) device designed to concentrate oxygen (O2) from ambient air and deliver the concentrated O2, typically through an attached nasal cannula, to a patient requiring oxygen therapy. It processes the air through an internal filtration system, e.g., a molecular sieve (zeolite granules or membranes), having a large total surface area to separate nitrogen (N2) from the air. It typically consists of an air compressor, filters, dual chambers, a reservoir and controls. The O2 concentration is variable depending on the flow rate utilized. It is typically wheeled but is designed to be placed in one location, e.g., an institution or a home setting.
