What makes the Welch Allyn Ear Wash System truly revolutionary is its built-in Hydrovac Action. This proprietary technology features simultaneous irrigation and suction capabilities, which means all discharge is directed away from you and the patient. And since you can easily control and monitor suction, water temperature, and pressure levels, the Ear Wash System is ideal for patients of all ages. What's more, it comes with over ten feet of clear, heavy-duty plastic tubing that lets you position the patient almost anywhere in the room, as well as visualize the process.
