Aquastar 2.0 Water stimulator, 230V - 50Hz

The caloric stimulator

The Aquastar water caloric stimulator is a medical device manufactured in Belgium by Instrumentation Difra SA. The caloric water stimulator is a device that delivers a jet of water into the auditory canal at a controlled flow rate and temperature, and is designed to test the vestibular function of a patient's body balance system. Vestibular stimulation of the semicircular canals produces involuntary eye movements.

Aquastar

The Aquastar offers many possibilities for caloric challenges: easy to use, high-precision temperature control. The handle and double hose allow direct stimulation with water at the right temperature. Its removable cannula and disposable silicone tips make for easy hygiene management. Aquastar is ideal when water can be used for stimulation in examination rooms where a water inlet and outlet are available.

Temperature setting

The temperature is selected by means of a simple rotary switch, each of its four positions allowing a predefined temperature to be set. Each temperature can be adjusted up to 48°C, in 0.2°C steps. Default values are 27°C, 30°C, 37°C and 44°C. The temperature is reached within 180 seconds from start-up or any other temperature. A large display shows the actual temperature.

Stimulation time settings

An internal chronometer, with a second rotary switch, enables you to select the stimulation time. Five stimulation times are available: 20, 30, 40, 50 and 60 seconds, simply by turning the switch. Visual and audible indications on the display help the examiner to perform the caloric test simply and accurately. During the stimulation period, the reaction period and fixation period will be delimited by these visual and audible indications.
