A diagnostic caloric vestibular stimulation system is a medical device assembly used to assess a patient’s vestibular function by introducing controlled streams of warm or cool air or water into the ear canal. This stimulation induces involuntary eye movements known as nystagmus, which are measured to evaluate balance function and assist in diagnosing vestibular disorders or assessing brainstem integrity.
Such systems are regulated as diagnostic medical devices and typically include components like pumps, valves, heaters, and regulators to precisely control the temperature and flow rate of the irrigant. They are intended for use in clinical settings such as ENT departments and are supplied as complete systems for professional use, not as single-use or disposable items.
