INTERNAL SCHEMATICS OF A WELCH ALLYN ENDOSCOPE
The following internal schematics have been provided to assist users in better understanding the intricate
construction of Welch Allyn endoscopes. Knowledge of the various internal channels and tubes within an
instrument and their relationship to each other helps facilitate the reprocessing of the endoscope.
The FL-100 intubating fiberscope and its components have been specifically designed for efficient and effective
reprocessing before each use by either a manual or automated method.
Connectors on all Welch Allyn cleaning/disinfecting adaptors and scope inlet ports incorporate standard size
luer-lock and/or luer-slip fittings to easily accommodate reprocessing devices or systems available from other
manufacturers.
The internal schematics show that the Welch Allyn cleaning system promotes efficient unidirectional flow of solu-
tions. Starting from the suction nipple at the control body, solutions travel up to the valve cylinder, pass through
the channel in the insertion tube and finally exit the channel opening at the distal tip of the scope. The elimina-
tion of multiple branching channels, combined with a direct pathway for solutions to travel, maximizes flow effi-
ciency and ensures contact of disinfectant/sterilant with all internally exposed channel surfaces.
WARNING (USA): It is imperative that flexible endoscopes and other semi-critical devices
be reprocessed using at least high-level disinfection with an EPA registered sterilant/
disinfectant. It should be noted that any endoscope automated reprocessing device or
system* must be cleared for marketing by the FDA via the 510 (k) premarket notification
or PMA approval process. Only reprocessing solutions/systems satisfying the above
conditions and tested and found to be compatible by Welch Allyn should be used with
Welch Allyn products.
*Liquid chemical germicides (disinfectants/sterilants) to reprocess medical devices come under FDA
regulation and new products must, therefore, undergo a 510 (k) premarket notification submission
prior to introduction into interstate commerce.
