Indications for Use
The UltraMaxO2 Oxygen Analyzer is a tool used to measure oxygen purity, flow and pressure at the outlet of an oxygen concentrator. The UltraMaxO2 Oxygen Analyzer is intended to be used in an environment where oxygen concentrators are being serviced or repaired. This includes Hospitals, Nursing Homes, Extended Care Facilities, Patient Homes, and Respiratory Device Service and Repair Centers.
Device Story
UltraMaxO2 is a handheld, battery-powered ultrasonic oxygen analyzer used by technicians to verify oxygen concentrator performance. Device inputs include gas samples from concentrator outlets; it measures transit time of ultrasonic pulses through a sample chamber to determine gas concentration based on molecular mass. Flow is calculated via differential transit time (against vs. with flow); pressure is measured via a separate sensor when the output port is blocked. Output is displayed on an LCD screen. Used in clinical and home settings for maintenance/repair; not for patient monitoring. Provides objective data on purity, flow, and pressure to ensure concentrator functionality, aiding in service decisions.
Clinical Evidence
No clinical studies were performed. Substantial equivalence is supported by non-clinical functional and performance testing comparing the device to legally marketed predicates.
Technological Characteristics
Ultrasonic oxygen sensing; ABS plastic enclosure; PVC tubing; nickel-plated brass fittings; pressure, temperature, and humidity sensors; LCD display. Powered by 2x AA alkaline batteries. Dimensions: 3.16" x 5.10" x 1.04".
Indications for Use
Indicated for use by service technicians or healthcare professionals in hospitals, nursing homes, extended care facilities, patient homes, and repair centers to verify performance (purity, flow, pressure) of oxygen concentrators during service or repair. Not for patient use or continuous monitoring of oxygen delivery.
Regulatory Classification

4) Description of the subject device:
Classification Panel:
ুন প্রায়
The UltraMaxO2 device is used for checking oxygen concentrator performance with the measure of oxygen purity, and flow at the outlet of an oxygen concentrator. Both the subject and predicate devices are capable of measuring oxygen concentration with an accuracy of at least +/- 3%. In addition, the subject and predicate devices are capable of measuring flow from 0 to 10 LPM with an accuracy of +/-
1 of 3

{1}------------------------------------------------
0.2 LPM. The subject and predicate devices are battery powered and use ultrasonic based oxygen sensing. These devices are not intended to be used by patients who are prescribed oxygen, nor are they intended to continuously monitor or confirm oxygen delivery to a patient. As per predicates listed above, the indication noted has been cleared by the FDA.
The UltraMaxQ2 Oxygen Analyzer functions by passing an ultrasonic pulse through the gas sample and measuring the amount of time required for the pulse to transit the sample chamber. The transit time is converted into a gas concentration via calibration data stored in the device. This can be done because the transit time varies according to the molecular mass of the gas in the chamber. Flow is determined using the difference between the ultrasonic pulse traveling against the flow and the ultrasonic pulse traveling with the flow. Pressure is measured using a separate pressure sensor that measures the pressure build-up in the device when the output port is blocked. The pressure is displayed in either kPa or PSI determined by a user operable switch in the battery compartment.
The materials of the UltraMaxO2 include ABS plastic for the enclosures and the ultrasonic oxygen sensor tube body, adhesive backed Polycarbonate labels, PVC tubing and nickel plated brass fittings for the flow path, electronic circuitry including transducers/receivers, pressure, temperature and humidity sensors and an LCD screen. Further detail concerning components is included as appropriate within the 510k submission.
5) Statement of indication for use:
The UltraMaxO2 Oxygen Analyzer is a tool used to measure oxygen purity, flow and pressure of an oxygen concentrator. The UltraMaxO2 Oxygen Analyzer is intended to be used in an environment where oxygen concentrators are being serviced or repaired. This includes Hospitals, Nursing Homes, Extended Care Facilities, Patient Homes, and Respiratory Device Service and Repair Centers.
6) Technological characteristics:
The technological characteristics of the design, materials, chemical composition, and energy source, etc. of the UltraMaxO2 Oxygen Analyzer are, for the most part, the same as the predicate devices identified in 3) above. Maxtec has not introduced any new technological characteristics for the UltraMaxO2 device.
- Non-clinical functional and performance tests for substantial equivalence testing and the results a. are noted in the attached table.
- No clinical studies were performed No clinical studies were performed for the UltraMaxO2 as the b. device represents a well known technology for a recognized indication as evidenced in Section 5.0 by comparison to the predicate devices currently cleared for sale in the US market.
- 7) The conclusion drawn from the non-clinical and clinical tests demonstrate that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate devices identified in 3) above.
