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.
