The device description explicitly states "There is no other electronics or software in the NPTLOX." and the document does not mention AI, DNN, or ML.
Yes
The device is described as providing "therapeutic oxygen to patients" and has a predicate device explicitly named "Portable Therapeutic Liquid Oxygen (PTLOX)".
No
Explanation: The device is designed to convert liquid oxygen to gaseous oxygen for therapeutic delivery to patients, not to diagnose a condition or disease.
No
The device description explicitly states, "There is no other electronics or software in the NPTLOX." The device is a hardware system for converting liquid oxygen to gaseous oxygen.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to convert liquid oxygen to gaseous oxygen for delivery to patients in military settings. This is a therapeutic use, providing a substance directly to the body for treatment.
- Device Description: The description details a system for storing and converting liquid oxygen and delivering it as a gas for breathing. It mentions connections for flow control valves, resuscitators, and ventilators, all of which are used for direct patient care.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
Therefore, the NPTLOX is a medical device used for oxygen therapy, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The NPTLOX is intended to convert liquid oxygen to gaseous oxygen (99.9% based on medical grade liquid oxygen) for delivery at 50 psig nominal for military use settings only.

Device Description
The NPTLOX is a portable, thermally insulated container designed to store liquid oxygen (99.9%) and convert the liquid oxygen to gaseous form, which provides therapeutic oxygen to patients. This equipment meets the Aero-medical mission requirements for gaseous oxygen to be delivered to patients in the three methods listed below.
- 1240 DISS Flow control valves and humidifier bottles
- Laerdal Silicone Adult Resuscitators with 2500 ml reservoirs
- Impact 754 Eagle Ventilators
The NPTLOX has six outlet ports that are capable of delivering oxygen to a maximum of six ambulatory or litter patients according to one or more of these approved methods.
The system will be filled by current liquid oxygen storage/filling systems used in the United States Military. The design of the NPTLOX is a modification to the existing predicate device, the Portable Therapeutic Liquid Oxygen (PTLOX) 510(k) K880183. The major modifications are an improvement in maximum oxygen delivery rate, increased number of patient outlets and increased oxygen capacity.
The NPTLOX provides gaseous oxygen to patients through 6 outlet ports at an outlet pressure of 50 ± 5 psig. The 6 outlet ports have a maximum combined system outlet flow of 66 LPM. This continuous flow rate is based on a design standard of 11 LPM per outlet fitting. The system is capable of flowing at least 60 LPM to meet the ventilator peak flow requirement. The NPLTOX has an accessory kit that includes three of each of the following: medical hoses, 0-15 LPM flow control valves, and humidifier bottles. The LOX capacity of the system is 20 liters. Oxygen delivery pressure is displayed via a pressure gauge. The LOX quantity can be periodically displayed via a LOX quantity indicator that is powered by two 9 volt batteries. There is no other electronics or software in the NPTLOX.

Comparison with the PTLOX: Both devices include a vacuum insulated cryogenics container, with the LOX capacity and the resultant dimensional increase being the significant change. The system has been optimized in the NPTLOX to improve the normal evaporation rate, allowing for less liquid oxygen loss during standby.
Testing: Extensive capability, performance, and environmental testing has been accomplished on the NPTLOX with no issues arising regarding its safety and efficiency. The combined testing and analysis of resplits provides assurance that the device meets its specifications and is safe/and effective for its intended use.

Dear Ms. Hunnicutt:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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. In addition, if you wish to change or expand your current indications for use to include non-military environments, you will need to submit a new 510(k) premarket notification, and receive FDA clearance prior to marketing the device.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
