Welch Allyn Ear Wash System Directions For Use Manual page 19

Directions for use
• To remove any stagnant solution in the tubing, place the open
end in the sink. Squeeze the actuator and the solution will run out
into the sink basin.
• Allow the chamber to drip dry. Place the unit in its holding
container.
• To facilitate a recommended thorough flush and faster drying
time, pour isopropyl rubbing alcohol inside the chamber and
hoses.
To Disinfect the Unit
Follow Cleaning instructions, except replace the soapy water with a 2 cup
solution of isopropyl rubbing alcohol or a 10% bleach/90% water solution.
Rinse handle thoroughly with water after cleaning solution is used.
To High Level Disinfect the Unit
• Prepare at least 2 cups of .55% Ortho-Phthalaldehyde solution
(Welch Allyn recommends the use of Cidex OPA).
• Pour at least 2 cups of the solution into the top opening of the
coupler.
• Replace the chamber on the faucet and submerge the handle
interface surface (where the tip attaches) into the solution. Turn on
the water. Do not squeeze the actuator. After half of the solution is
removed, turn the water off.
• Remove handle from solution and rest it in the handle rest/grip ring.
This will trap the solution in the return line and allow effective
disinfection. Follow the manufacturers recommendations on soak
times for maximum benefit.
• Remove the chamber from the faucet.
• To remove any residual disinfecting solution in the tubing, place the
open end in the sink, squeeze the actuator and the solution will run
out into the sink basin.
