Intended Use

The Oxygen Concentrator is indicated for the delivery of supplemental oxygen in the home or medical institutions. The device is not intended for life support nor does it provide any patient monitoring capabilities.

Device Story

Prescription oxygen concentrator for home or institutional use; provides supplemental oxygen. Operates via molecular sieve technology; compressor draws room air into holding tank; air pressurized into aluminum welded molecular sieve tanks; nitrogen removed via adsorption; oxygen-enriched gas (approx. 93%) delivered to patient. Repetitive cycle uses generated oxygen to flush saturated sieve tank while maintaining continuous flow. Includes optional oxygen alarm and pediatric flowmeter. Not life-supporting or life-sustaining. Healthcare providers use output to manage patient oxygenation levels; benefits patients by providing inexpensive, continuous supplemental oxygen supply without requiring continuous source of purified oxygen.

Clinical Evidence

Bench testing only. Device meets requirements of FDA-recognized standards and performance specifications of predicate devices.

Technological Characteristics

Molecular sieve oxygen concentrator; aluminum welded sieve tanks; compressor-driven vacuum system. Delivers ~93% oxygen. Includes optional oxygen alarm and pediatric flowmeter. No software-based algorithms or connectivity described.

Indications for Use

Indicated for patients requiring supplemental oxygen in home or medical institutional settings. Not for life support; no patient monitoring capabilities.

Regulatory Classification

Identification

A portable oxygen generator is a device that is intended to release oxygen for respiratory therapy by means of either a chemical reaction or physical means (e.g., a molecular sieve).

Comparison to Currently Marketed Devices 9.5

The Merits Health Products Oxygen Concentrators are substantially equivalent to the OxLife Concentrators (K955549 and K971964), AirSep NewLife Oxygen Concentrators (Last Submission - K960309) and Invacare Oxygen Concentrators (K904087).

#### 9.6 Device Description

The Merits Health Products Oxygen Concentrators are prescription devices designed to provide an inexpensive supply of supplemental oxygen in a home or institution without a continuous source of purified oxygen. They are not lifesupporting nor life-sustaining devices. The devices operate through the use of molecular sieve material that binds with the water and nitrogen in filtered room air to leave a gas that is approximately 93% oxygen when delivered to the patient. The compressor creates a vacuum to draw room air into a holding tank. At the same time, downstream of the compressor, the air from the previous cycle is pressurized into one of the two aluminum welded molecular sieve tanks. As the oxygen is forced out of the end of the tank, it enters a 'T' fitting that directs most of the gas to flush the nitrogen out of the second molecular sieve tank into the ambient air. The remaining oxygen is delivered to the patient. On the next cycle, the air is directed into the second molecular sieve tank with the oxygen generated flushing the first tank and continuing the supply to the patient. This repetitive cycle generates the oxygen necessary to flush and prepare the saturated sieve tank while supplying the patient with a continuous flow of high concentration oxygen. Other options will include an Oxygen alarm and a pediatric flowmeter.

Dear Mr. Leichter:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this
