The PROS Vented Otoblock (Pressure Relief Oto-Dam System) is a professional-grade ear dam used during hearing aid earmold impression-taking procedures. The built-in ventilation tube relieves air pressure in the ear canal while the impression material sets, improving patient comfort and impression accuracy.
Each pack contains 24 vented ear dams measuring 13mm in diameter (color-coded blue for size identification) along with a grooved insertion tip compatible with ENT Pocket Light, Otoprobe, and Disposable Ear Lights. The insertion tip aids precise placement deep in the ear canal before impression material is introduced.
These are a standard consumable supply used by audiologists, hearing instrument specialists, and ENT clinics. Item number 20305 corresponds to the PROS vented design with insertion tip included.
