Important Information

Reprocessing The endoscope must be properly reprocessed, by cleaning, disinfecting and/or sterilizing, before its first use and after each subsequent use. Using an endoscope in a procedure that has not been properly reprocessed presents an acute infection-control risk to both the patient and medical personnel performing or assisting in the procedure. Always wear appropriate personal protective equipment when reprocessing the endoscope, such as a gown, gloves, and face and eye shields. Use extreme care when reprocessing the endoscope. Do not forcefully pull, push, or drag wipes, towels, or cloths along the Insertion Tube. The use of excessive force could damage the endoscope. Do not immerse the endoscope in disinfectant solution for long periods of time (>1 hour). Prolonged immersions may damage the outer coverings of the endoscope and allow fluid infiltration. Do not place the endoscope in or near contaminated areas after it has been reprocessed. Doing so can recontaminate the endoscope and require reprocessing to be repeated. Do not place the endoscope in awkward or confining areas between procedures as this could result in equipment damage.

4 Preparation, Inspection and Operation

If an abnormality is detected during endoscope preparation, do not use the endoscope; refer to the tables in Chapter 7, Troubleshooting. If the problem cannot be solved using the information in that chapter, contact your regional distributor or Cogentix Medical Customer Service. When using the Slide-On® EndoSheath® Technology with the endoscope, refer to the Instructions-for-Use that are shipped with the Sheaths. These instructions will provide complete details on preparing, installing and removing the disposable Sheath. During the procedure, the temperature at the distal end of endoscope may exceed 41oC (106 oF) due to the intense endoscope illumination. Surface temperatures over 41oC (106 oF) may cause mucosal burns. Always use the minimum level of illumination necessary for adequate viewing. Whenever possible, avoid close stationary viewing and do not leave the distal end of the endoscope in close proximity to mucous membranes for a long time. The Slide-On® EndoSheath® Technology is shipped sterile and intended for a single use only; do not reuse it. When the procedure is complete, remove the Sheath from the endoscope and dispose of it. Reusing the Sheath can damage it, and in turn cause endoscope damage. In addition, a reused Sheath presents a marked infection-control risk to the next patient. If you are not using the Slide-On® EndoSheath® Technology, ensure that the endoscope has undergone the appropriate disinfection process. Please refer to Chapter 5, Reprocessing, for compatible reprocessing methods and procedures. A complete review and understanding of the DPU-5000/7000 Series User’s Manual is recommended before using the ENT5000/ENT-7000 Flexible Video Nasopharyngo-Laryngoscope.
