Introduction
The Eclipse 2, Personal Ambulatory Oxygen System with AutoSat Technology is a portable medical
device used to extract oxygen from the atmosphere, concentrate it to greater than 90% and present it to
the patient. The device will operate in continuous flow or Pulse Flow Modes. In Continuous Flow Mode
the oxygen is provided at a constant flow rate between 0.5 and 3.0 LPM. In Pulse Flow Mode, oxygen is
supplied in a bolus at the beginning of each inspiration, providing a selectable range setting of flow
between 1.0 and 6.0. A setting of 1 in Pulse Flow Mode delivers the equivalent amount of oxygen
(FIO2) as a Continuous Flow Mode setting of 3 LPM.
The Eclipse operates from either external power or from an internal rechargeable Power Cartridge. The
system includes a “Smart Battery” charger that recharges the internal Power Cartridge whenever the
Eclipse is connected to external power. The system monitors and controls both the power source and
the Power Cartridge charger.
ATF® Concentrator Module
The Eclipse uses a passive system to separate oxygen from air. Air flows into the Eclipse where it is
filtered and then enters the compressor. Pressurized air flows from the compressor into the ATF®
Concentrator Module where it is separated into oxygen and nitrogen components. The air separation
process uses a rotary valve system to force air through a series of pressurized sieve beds. Through a
process known as “pressure swing adsorption,” nitrogen molecules are collected on an adsorbent
material allowing the concentrated oxygen to be forced through a sieve bed into the product tank. The
nitrogen molecules are then purged from the adsorbent material using a vacuum pressure cycle.
Oxygen flows from the product tank through a HEPA filter and past a sensor that measures flow and
concentration. A flow control valve regulates the flow of concentrated oxygen presented to the patient.
The process is continuously repeated during operation.
