2 Standard Laryngoscope Blades and Handles Welch Allyn
Disinfection/Sterilization (Minimum High Level Disinfection Required)
Contact Welch Allyn regarding the use of other cold soak solutions intended for
disinfection or sterilization. For recommended exposure times and solution
concentrations, refer to solution manufacturer’s instructions.
Prior to immersion, verify that the lamp is secure. Immersion with lamp removed or
improperly secured will result in damage to the electrical contacts.
Steam Autoclave is appropriate.
Ethylene Oxide is appropriate with gas concentrations of 10% to 100%.
Standard Laryngoscope Handle
Disinfection/Sterilization
New Welch Allyn standard battery handles are compatible with steam autoclave
sterilization, however, DO NOT flash autoclave. (Please follow the same parameters as
outlined under laryngoscope disinfection/sterilization above.) These handles can be
identified by the term AUTOCLAVE located on one side of the hook on neck. Older Welch
Allyn handles ARE NOT autoclavable and will not have this marking. Prior to autoclaving,
unscrew the bottom cap and remove the batteries. The main handle and cap will also
withstand exposure to ethylene oxide. (figure 2)
Welch Allyn standard battery handles are not designed for cold soak disinfection.
Exposure to these environments will severely damage the electrical components of the
instrument and since fluid may be retained within the instrument there is a possibility of
short circuiting the instrument or drainage onto the patient. The battery handle can be
cleaned by wiping down with a cloth or towel dampened with a solution of 70% isopropyl
alcohol or a 14 day glutaraldehyde solution.
