Intended Use
Refurbished Replacement Column (Sieve Bed) are regular replacement parts for Inogen One G3 Oxygen Concentrator. The Inogen One Oxygen Concentrator is used on a prescriptive basis by patients requiring supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal cannula to channel oxygen from the concentrator to the patient. The Inogen One Oxygen Concentrator may be used in a home, institution, vehicles and various mobile environments.
Device Description
The subject device is a compatible replacement part of the Inogen One G3 portable oxygen concentrator. ("POC"). Standard portable oxygen concentrators generate oxygen from room air by use of a sieve bed that removes nitrogen, other gases and impurities from the room air and generates oxygen for patients requiring supplement oxygen. These sieve beds must be replaced on a schedule in order to maintain the POC's ability to deliver the require % oxygen. The subject device is refurbished with existing Inogen One G3 components with a new sieve bed. The final product is equivalent to the Inogen one G3 replacement sieve bed cartridge.
More Information

No
The device is a refurbished replacement part (sieve bed) for an oxygen concentrator and the description focuses on its function in generating oxygen and meeting performance standards, with no mention of AI or ML.

No.
The device itself is a replacement part for an oxygen concentrator, which is a therapeutic device. However, the replacement column (sieve bed) alone does not administer therapy; it enables the therapeutic device to function correctly.

No

The device is described as a replacement part (sieve bed) for an oxygen concentrator, which supplies supplemental oxygen to patients. Its function is to generate oxygen by removing nitrogen and other gases from room air. There is no information suggesting that it is used to identify or diagnose a disease or condition.

No

The device is a refurbished replacement part (sieve bed) for an oxygen concentrator, which is a hardware component. The description focuses on the physical characteristics and performance of this hardware part.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The device is a replacement part for an oxygen concentrator used to provide supplemental oxygen to patients. This is a therapeutic and life-support function, not a diagnostic one.
  • Device Description: The device is a sieve bed that filters air to produce oxygen. This is a mechanical process, not a test performed on biological samples to diagnose a condition.
  • Lack of Diagnostic Activity: There is no mention of the device being used to analyze biological samples (like blood, urine, tissue, etc.) or to provide information for the diagnosis, monitoring, or treatment of a disease or condition based on such analysis.

IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic purposes. This device does not fit that description.

  • Oxygen Purity over time per applicable parts of ISO 80601-2-69:2020 clause 201.12.1.103 (Medical electrical equipment - Part 2-69: Particular requirements for the basic safety and essential performance of oxygen concentrator equipment) testing was done at intervals up to 8 hours with performance compared to the predicate.
  • Leakage
  • Package integrity

Biocompatibility

  • ISO 18562-2:2017 Particulate Matter compared with predicate and subject device after 10 cleaning / refurbishing cycles
  • ISO 18562-3:2017 VOC compared with predicate and subject device after 10 cleaning / refurbishing cycles

Device Description:

The subject device is a compatible replacement part of the Inogen One G3 portable oxygen concentrator. ("POC"). Standard portable oxygen concentrators generate oxygen from room air by use of a sieve bed that removes nitrogen, other gases and impurities from the room air and generates oxygen for patients requiring supplement oxygen.

These sieve beds must be replaced on a schedule in order to maintain the POC's ability to deliver the require % oxygen. The subject device is refurbished with existing Inogen One G3 components with a new sieve bed. The final product is equivalent to the Inogen one G3 replacement sieve bed cartridge.

Principle of Operation:

The composition of air (78% Nitrogen, 21% Oxygen and 1% other gases like Carbon Dioxide, Argon, etc.) clearly shows that air is mainly comprised of two gases: Nitrogen and Oxygen [together 99%]. If Nitrogen is removed from air, the primary gas remaining would be Oxygen with purity of about 90-95%. An Oxygen Concentrator uses this idea with the basic principle of Pressure Swing Adsorption (PSA) to deliver 90-95% pure oxygen. Since the subject device is a refurbished sieve bed utilizing the Inogen One G3 components with the sieve bed replenished.

Indications for Use:

Refurbished Replacement Column (Sieve Bed) are regular replacement parts for Inogen One G3 Oxygen Concentrator.

The Inogen One Oxygen Concentrator is used on a prescriptive basis by patients requiring supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal camula to
