Invacare® HomeFill® II Oxygen System

8 Technical Data

8.1 Technical Description

The HomeFill II Oxygen System (IOH200AW) is an
electro-mechanical prescription system for use in the home.
Its intended function and use is to supply pressurized oxygen
to fill Invacare proprietary gas cylinders for ambulatory
use while the patient receives therapeutic oxygen from an
oxygen concentrator. The IOH200AW gas system is designed
for use with oxygen concentrators that meet the input
specifications for pressure, flow, and oxygen purity.
The HomeFill II Oxygen system consists of IOH200AW gas
compressor, connection tubing, and the Invacare supplied
portable gas cylinders with the integral flow regulator and
interlocking fill fitting.
The IOH200AW compressor consists of a multistage
compressor, internal reservoir, control electronics with
an integral oxygen concentration sensor, interlocking fill
fitting, inlet fitting, and drive motor. The compressor
operation is controlled by the electronics assembly. The
motor/compressor is allowed to fill a cylinder only when the
oxygen concentration of the inlet gas stream is greater than
90% and the cylinder pressure is not already greater than
1500 PSI (10342 kPa). The motor/compressor fill operation is
completed when the gas in a cylinder reaches the maximum
fill pressure of 2000 PSI (13786 kPa).
The IOH200AW compressor can fill cylinders for portable
use by ambulatory patients. The Invacare supplied portable
gas cylinders have an interlocking fill fitting that mates only
with the Invacare IOH200AW compressor assembly. The gas
34
cylinder also contains an integral flow regulator with fixed,
selectable flow settings.
