Thank you for purchasing the Welch Allyn Ear Wash System.
The Welch Allyn Ear Wash System provides a safer and more effective
way to remove cerumen. This method of irrigation is much cleaner and
safer than other irrigation methods currently on the market. The Welch
Allyn Ear Wash System provides the following features:
• Patient Comfort - Hydrovac action
• Patient Safety- High temperature water shut-off
• Water pressure regulation inside chamber
• User Friendly - Visual temperature feedback sensor
• Superior Engineering - Fully functional at variable water pressures as
well as different faucets
This manual describes how to operate and maintain the Welch Allyn Ear
Wash System. Please follow these instructions to ensure many years of
accurate and reliable service. Carefully read the instructions regarding the
method on “Using the Ear Wash System” on page 8 to minimize patient
discomfort and to avoid the risk of perforating a patient’s tympanic
membrane. For additional information on cerumen types and the irrigation
process, see the “Types of Cerumen” section.
