SECTION 3—TECHNICAL
DESCRIPTION
The Invacare portable concentrator is to be used by patients
with respiratory disorders who require supplemental oxygen.
The device is not intended to sustain or support life.
The oxygen concentration level of the output gas ranges from
87% to 95.6%. The oxygen is delivered to the patient through
the use of a nasal cannula. When the demand for oxygen is
detected, the oxygen is delivered through pulsed flow with
pulse flow settings of 1 through 5.
The Invacare portable concentrator uses a molecular sieve and
pressure swing adsorption methodology to produce the
oxygen gas output. Ambient air enters the device, is filtered
and then compressed. This compressed air is then directed
toward one of two nitrogen adsorbing sieve beds.
Concentrated oxygen exits the opposite end of the active sieve
bed and is directed into an oxygen reservoir where it is
delivered to the patient in specific volumes during the
inhalation portion of a detected breath.
The Invacare portable concentrator is capable of operation by
the patient in a home environment, in an institutional
environment or in a vehicle or other mobile environment.
Device standard power options include an AC to DC
switching power supply operating from AC power outlet (120
VAC/ 60 Hertz or 230VAC/50 Hertz nominal), a DC to DC
switching power supply operating from accessory outlets
typically found in a mobile vehicle type environment (12 VDC
nominal) and a supplemental rechargeable battery.
