SAUERSTOFFANREICHERUNGSGERÄT MIT ZWEI BETRIEBSARTEN

摘要

Oxygen concentrator system comprising a portable oxygen generator unit and a stationary base unit, wherein the portable oxygen generator unit and the stationary base are adapted for operation in a coupled mode and an uncoupled mode. In one embodiment, oxygen-rich gas is generated by the portable unit in the coupled mode and transferred to the stationary base unit, and product oxygen-rich gas is delivered from the stationary unit to the user. The stationary base unit may provide for pump boost or additional feed air to increase the oxygen-rich gas generation rate in the portable unit. Alternatively, the stationary base unit may have a stationary air separation device, and in the coupled mode the oxygen-rich gases from the portable unit and stationary base unit may be combined and delivered as product oxygen-rich gas from the stationary base to the user. The combined product gas may be humidified in the stationary base unit. In another embodiment, in the coupled mode, humidified oxygen-rich gas is generated in the stationary base unit, combined outside of the base unit with non-humidified oxygen-rich gas from the portable unit, and delivered as product oxygen-rich gas to the user.
