prior to disinfection or
sterilization:
1. Immerse all components in a neutral pH enzymatic
cleaning solution as directed by solution
manufacturer’s instructions.
2. While components are immersed in the cleaning solution,
use a soft-bristled brush to clean all component surfaces
(the blade, retaining screw, and fiber optic light carrier)
until all visible contamination is removed.
3. Thoroughly rinse all components in one of the following:
potable filtered water, softened water, or per cleaning
solution manufacturer instructions, or per facility
instructions to remove cleaning solution.
After cleaning, dry all components with a clean cloth or allow
to air dry.
1. Inspect each component area (per Figure 3) for damage or
deterioration. Also, inspect the following areas for
deterioration:
• hooks of laryngoscope blade (1) and fiber optic light
carrier (2)
• light fiber of light carrier (2)
• threads of blade (1) and screw (3)
WARNING: Discard any component that shows
evidence of damage or deterioration.
Contact Welch Allyn for component replacement.
2. Reassemble the blade assembly by reversing steps
illustrated in Figure 2.
3. Attach blade assembly to a clean and disinfected test
handle in known working condition. Ensure that:
• Blade assembly engages and locks onto handle.
• Blade assembly deploys into its locked position on
handle AND the handle’s lamp illuminates.
• Verify that light output is satisfactory.
If the lamp fails to light or output is low, check or
replace the fiber optic light carrier.
After cleaning, choose either cold solution high level disinfection method (page 4)
or one of four sterilization methods (page 4-5).
