SECTION 3—TECHNICAL
DESCRIPTION
The Invacare transportable oxygen 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. The transportable oxygen concentrator provides two modes of
operation; pulse flow and continuous flow. In pulse flow, when the
demand for oxygen is detected, the oxygen is delivered with pulse flow
settings of 1 through 5. In continuous flow, oxygen is continuously flowing
with settings from 0.5 LPM to 3.0 LPM.
The Invacare transportable oxygen 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 transportable oxygen 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 supply
operating from accessory outlets typically found in a mobile vehicle type
environment (12 VDC nominal) and a rechargeable battery module.
