The Oxygen Concentrator is a portable concentrator which could utilize a molecular sieve and pressure swing adsorption to produce oxygen. The device can separate nitrogen by absorbing through the molecular sieve when the room air enters the device and allows the enriched oxygen to be collected. The device could provide approximately 90~96% of oxygen to patients on a continuous flow basis at a rate of 1L/min to 5L/min.
A mobile/portable 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 used in a home, institution, or a vehicle and typically has internal batteries for transportable use.
