Air Caloric Irrigator The Air Fx caloric irrigator delivers a precisely controlled temperature and flow rate of cool or warm air to evaluate the horizontal semicircular canal during caloric testing. Features The Air Fx caloric irrigator utilizes a lighted otoscope hand piece. The otoscope hand piece features replaceable tips, a magnifying lens and a cool, bright white LED light pipe for illuminating the tympanic membrane (TM) without obstructing the airflow or the view of the TM. The Air Fx also has a long air hose of 9 feet for ease in irrigating the patient. The Air Fx uses a built-in reservoir and peltier device to cool the air down to 20°C regardless of ambient room temperature. The internal heater can raise the testing temperature to 50°C. The Air Fx uses audible and visual cues during testing. A bright LCD display and front-panel buttons provide easy access to control irrigation. The Air Fx can also work as a standalone unit or can be interfaced with the Spectrum software.
