Product Description
The AiSW2101 Middle Ear Analyzer (Type 1) is a clinical diagnostic impedance audiometer designed for comprehensive middle ear function assessment. It provides fast, accurate, and objective measurements without relying on patient subjective responses, making it especially suitable for infants, children, and uncooperative patients.
The system integrates an admittance measurement unit, pressure control system, and acoustic reflex stimulation system to evaluate the acoustic compliance of the tympanic membrane and ossicular chain. By analyzing sound pressure variations within the ear canal, the device enables clinicians to diagnose various middle ear pathologies effectively.
