Directions for use
5. It is important to aim the stream of water away from the longitudal
axis of the ear canal and toward the ear canal walls by tilting and
rotating the handle during the irrigation. Flood the ear with water. The
suction return system will return the discharge away from the ear.
6. During the irrigation, provide inquiries about patient comfort to
provide confidence. Periodically stop irrigation. View the ear canal
(using an otoscope) to check on progress. (Wax evacuation is not
always evident watching the ear tip/suction tubing.)
7. If the temperature of the irrigating water becomes too hot, the unit
will restrict the flow to the handle, while continuing to discharge out
the bottom of the unit. For the unit to reset, bring the water
temperature down to a safe level by adjusting the knobs on the
faucet until the water cools sufficiently.
8. Release the actuator and keep the ear tip in the canal for 5 to 10
seconds to vacuum any residual irrigating water.
The procedure typically takes 30 seconds to 5 minutes
Note
depending on the type of cerumen and whether or not a wax
softening agent is used. In severe cases, the process could take
longer.
9. When the irrigation is complete,
grasp the tab located on the
disposable ear tip and pull the ear
tip off of the handle with a
downward motion. Please place in
an appropriate receptacle.
WARNING If there is no water flow out of the ear tip and the
actuator is depressed, check to see if the hot water shut-off has
tripped by running cold water through the unit. This should restore
water flow to the handle.
