# Device Description

The Rugged Oxygen Generator (ROG) is intended for environment such as emergency use, home use, and commercial use and is OTC. The ROG is designed to provide supplemental oxygen and is a single use product. The ROG is a chemical oxygen generator that produces a minimum of 90 liters of oxygen at ≥96% purity for minimum of 15 minutes with an average flow rate of 6 liters per minute or greater. There is a need for oxygen in a variety of applications/locations where compressed oxygen cylinders are not suitable.

#### Principle of Operation

The subject device is initiated though a friction interaction between an integrated phosphorous match and the candle block. To initiate, open the lid and turn the dial clockwise 2-3 times. The turning of the dial will rotate the match and screw the match down into the candle block. This will start the chemical reaction, which will produce oxygen. Once oxygen is flowing, close the lid and place the face mask onto patient.

# Indications for Use:

Intended to produce oxygen for emergency use at 6 LPM flow rate for at least 15 minutes (90 liters) for individuals 17 years and older requiring emergency or supplemental oxygen.

#### Patient Population:

For individuals 17 years and older requiring emergency or supplemental oxygen.

#### Environments of use:

Emergency use, home use, and commercial use

### Substantial Equivalence Discussion

The table above compares the key features of the proposed device with the identified predicate -ROG - K131016. The comparison demonstrates that the subject device can be found to be substantially equivalent to the predicate device.

# Indications for Use -

The indications for use are similar for the subject device when compared to the predicate device.

Discussion - The indications for use are similar.

#### Technology and construction -

The technology and principle of operation is similar for the subject device when compared to the predicate device. Discussion - Both the subject and predicate device have identical principles of Operation.

#### Environment of Use -

The environments of use are identical to predicate, which are Emergency, OTC, home and commercial settings.

Discussion - The environments of use are the identical.

#### Patient Population -

The patient population is similar for individuals requiring emergency oxygen. Discussion - The subject and predicate device patient populations are similar.

# Non-Clinical Testing Summarv

#### Bench testing -

Performance testing demonstrated that the subject device met its acceptance criteria. Testing included:

- Casing, Gas at patient temperature testing .
- Shock and Vibration
- Drop Testing .
- Sand and Rain Blow Testing ●
- Flow Duration .

Discussion - The test results are similar to the predicate and within pre-defined acceptance criteria.

#### Biocompatibility -

The sponsor performed ISO 18562-2 and ISO 18562-3 testing.

Discussion - The subject device was found to meet the applicable requirements for biocompatibility safety for the intended population

#### Discussion of Differences

The subject does not include oxygen tubing and mask as was included by the predicate device. The oxygen percent is 96% as compared to the predicate, which was 99%. The flow rate minimum, duration, and initiation of oxygen remain unchanged. The subject device also incorporates design updates from Molecular Product's own device - the predicate ROG - K131016.

{6}------------------------------------------------

The changes incorporated in the subject device do not raise any new concerns of safety of effectiveness.

# Substantial Equivalence Conclusion

Through testing outlined above, the sponsor has demonstrated that the subject device comparably performs to the predicate, and the subject device do not raise any new concerns of safety of effectiveness when compared to the predicate ROG - K131016.
