ENGLISH Intended Use The Welch Allyn Rigid Reusable & Single Use Sigmoidoscopes and Anoscopes are used to illuminate and facilitate the examination of the rectal and anal cavity. The instrument also provides a means of entry for surgical instruments into the rectal and anal cavity. Endoscopes and the insufflation system are categorized as semi-critical devices requiring high level disinfection and the illumination system is categorized as a non-critical device requiring low-level disinfection according to the Multi-society guideline for reprocessing flexible gastrointestinal endoscopes published by Gastrointestinal Endoscopy (volume 58, No. 1, 2003) and simultaneously in Infection Control and Hospital Epidemiology. Optional higher level processes have been included in these instructions. Refer to ASTM F1518-00, Standard Practice for Cleaning and Disinfection of Flexible Fiberoptic and Video Endoscopes Used in the Examination of the Hollow Viscera, for additional guidance on reprocessing of these devices/accessories. Although this standard is for flexible endoscopes, it contains information that can be applied to rigid endoscopes as well. Caution U.S. federal law restricts this device to sale by or on the order of a physician or licensed healthcare practitioner. This device should only be used by trained personnel. Caution Perform reprocessing immediately after each use. Caution Consult your facility's procedures and the reprocessing agents manufacturer's instructions for the agents reuse, recommended Personal Protective Equipment and other safety precautions such as ventilation, etc. Caution Examine surfaces of all components for wear or damage after cleaning, disinfection, and/or sterilization. Caution For cleaning and/or disinfection, use brushes appropriate for the size of the endoscope channel parts, connectors, and orifices (e.g. bristles should contact all surfaces). Cleaning/disinfection tools (brushes, etc.) should be single use or thoroughly cleaned, disinfected, and/or sterilized between uses. Caution Unless otherwise specified, perform all reprocessing procedures at ambient (room) temperature. Caution Clean and disinfect all devices or accessories per these instructions prior to returning to Welch Allyn (e.g. for repair and service). Caution Users are responsible to qualify any deviations from these procedures.
