The summary describes a standard oxygen concentrator using molecular sieve and pressure swing adsorption, with no mention of AI or ML.
Yes
The device is intended to provide oxygen therapy, which is a therapeutic intervention for individuals requiring low flow oxygen.
No
The device description indicates that the Twister Oxygen Concentrator produces concentrated oxygen for therapy, not for diagnosing conditions. Its intended use is to provide oxygen, not to identify medical conditions or diseases.
No
The device description clearly states it produces concentrated oxygen using a molecular sieve and a pressure swing adsorption process, which are hardware components.
Based on the provided information, the Twister Oxygen Concentrator is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Twister Function: The Twister Oxygen Concentrator is a device that provides oxygen directly to a person for therapeutic purposes. It does not analyze samples taken from the body.
The description clearly states its function is to "provide oxygen to persons requiring low flow oxygen therapy" and that it "produces concentrated oxygen from room air for delivery to a patient". This is a therapeutic device, not a diagnostic one.

Dear Ms. Cortelloni:
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 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 Existing major regulations affecting your device additional controls. 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 Failure to comply with the GMP regulation may result in assumptions. requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
