Maxtec UltraMaxO₂: ultrasonic O₂ analyser without sensor replacement for concentrator maintenance
The UltraMaxO₂ is specifically developed for biomedical technicians and maintenance services that check oxygen concentrators in home care, hospitals and rehabilitation centres. The device replaces the combination of an O₂ analyser, flowmeter and pressure gauge in one handheld instrument, and solves three problems that service technicians regularly face when maintaining oxygen concentrators.
First, traditional oxygen analysers require periodic sensor replacement, which brings costs, planning effort and the risk of measuring with an aged sensor. Second, a complete concentrator check normally requires several devices. Third, many analysers require field calibration with external calibration sources such as 100%-zuurstofffffflessen, which is a logistical burden in field service.
The UltraMaxO₂ solves each of these problems.
No sensor replacement, lower cost of ownership
Where traditional galvanic oxygen sensors use an electrochemical reaction that gradually consumes the sensor, the ultrasonic sensor works on the basis of the difference in the speed of sound between oxygen and nitrogen. Because no consumable reaction takes place, the sensor does not wear and replacement is not necessary throughout the entire life of the device. This completely eliminates the costs and logistics of sensor replacement programmes.
Integrated O₂, flow and pressure in one operation
The UltraMaxO₂ simultaneously measures oxygen percentage and flow rate. Checking the outlet pressure of an oxygen concentrator is easier than ever: by closing the outlet with a finger, the display automatically switches from O₂ and flow to pressure display. The pressure unit can be switched between psi and kilopascal via a switch in the battery compartment. One device thus replaces three separate measuring instruments.
No field calibration required
The UltraMaxO₂ has a built-in calibration verification function: press and hold the button and the display shows "cal ver" if the analyser is functioning correctly. If there is a problem, an error code appears. This eliminates the need for calibration with 100%-zuurstofffffflessen, which are difficult to transport and manage in field service. Service reports can record that the analyser has been verified, without an external calibration source.
Fast start-up and easy transport
The start-up time is less than 1 second. The user simply connects the tubing from the gas inlet of the UltraMaxO₂ to the outlet of the concentrator and reads the values directly on the large LCD display. The analyser weighs 181 grams, fits comfortably in the palm of the hand or a back pocket and comes with a protective silicone cover for transport.
