2. Endoscope Description

Figure 1. ENTity NasoView Endoscope Control Body (Handle) Control Body: Eyepiece: The eyepiece allows the user to visualize the image directly or to connect a standard video camera, still photography system, or teaching attachment to the endoscope. The eyepiece is compatible with most C-mount adapters and video camera systems. Call Optim LLC at +1.508.347.5100 or 800.225.7486 for information on video adapters, cameras, processors and monitors. Focus Ring: The focus ring adjusts the image to the user’s eyesight. Adjust the focus by rotating the Focus Ring (also known as the Diopter Adjustment Ring) clockwise or counterclockwise until the fiber pattern is in clear focus. Diopter Markings: If using a video camera, still photography system, or teaching attachment, the white dot on the Control Body must be aligned with the white dot on the Focus Ring (Diopter Adjustment Ring). The colored lines provide reference markers for various users of the same endoscope. Articulation Lever: The articulation lever controls the angular deflection of the Distal Tip. Light Switch Lever: The light switch lever controls the on / off and intensity of light output. Moving the lever towards the wider end of the intensity indicator increases the light intensity; moving the lever towards the narrower end of the intensity indicator decreases the light intensity. Identification Label: The laser marked label includes the identity of the endoscope by model, serial number, manufacturer, manufacturer telephone number and web address. It also includes the IPX7 rating and Type BF Part symbols. 5

Battery Door: The battery door seals the battery and electronics within the control body. Vent: Equalizes the air pressure inside the endoscope during storage and shipping when the Vent Cap is installed. It is also the connection to the Leak Tester (used to check that the endoscope is fully sealed and can be immersed in liquid or used for patient procedures). Vent Cap: Cap ON: The Vent Cap must be PLACED ON for aeration and shipping. The Vent Cap holds the Vent open and prevents damage caused by changes in pressure and temperature. Cap OFF: The Vent Cap must be REMOVED for patient use, leak-testing, and disinfection. Removing the cap allows the Vent to close, preventing fluid invasion. Insertion Tube: Depth Markers: Depth marks are located at 10cm and 20cm from the Distal Tip of the Insertion Tube. Bending Section: The bending section deflects up and down when the Articulation Lever is rotated. Distal Tip: The termination of the Image fiber bundle (at the Objective Lens) and the Illumination fiber bundles (Light Guides).

3. Endoscope Function and Operation Endoscope Preparation • • • •

Before use, the endoscope should be reprocessed. Please refer to the Care & Maintenance Section of this manual for proper reprocessing protocol. Before each procedure, visually inspect the Insertion Tube for holes, cuts or abrasions. Run one’s fingertips down the length of the Insertion Tube, feeling for the above defects. Do not squeeze the outer coverings tightly. Check the Distal Tip deflection by rotating the Articulation Lever clockwise and counterclockwise. Do not apply excessive force rotating the Articulation Lever. The endoscope articulates 135° Up and Down. Clean the Eyepiece and lens on the Distal Tip with an alcohol prep pad. Do not use abrasive cleaners on the lens surfaces.

Endoscope Operation •

Hold the endoscope so that the control body fits comfortably in one hand, allowing easy manipulation of the articulation lever with the thumb. Use the other hand to manipulate the Insertion Tube of the endoscope. CAUTION: Avoid excessive bending or twisting of the endoscope insertion shaft. While designed to bend, excessive pressure can damage the fibers and internal components. Do not manually bend the distal tip; always use the articulation lever to articulate the tip up or down.

Figure 3. Suggested Method for Holding the ENTity NasoView Endoscope During Use • • • • •

While viewing through the Eyepiece, rotate the Focus Ring clockwise or counterclockwise until the fiber pattern is in clear focus. When using a video camera, still photography system, or teaching attachment with the endoscope, be sure the white dot on the Control Body is aligned with the white dot on the Focus Ring. Turn on the light by rotating the lever on the side of the Control Body near the Articulation Lever. Adjust the brightness to the desired level by the rotating lever. Introduce the endoscope into the patient and operate the Articulation Lever as necessary to guide the Distal Tip & Insertion Tube for advancement and observation.

4. Care and Maintenance I – Method of Endoscope Reprocessing WARNING: Failure to comply with the following may result in damage to the endoscope and will void the product warranty. The ENTity NasoView endoscope is rated IPX7 for protection against ingress of water. The entire endoscope is submersible in water and disinfectant solutions. However, the endoscope should not remain immersed in water or cleaning solutions for prolonged periods of time. After the disinfection cycle has concluded, remove the endoscope from the disinfection solution, dry the endoscope, and store the device in a clean and dry environment. Thorough cleaning and rinsing are the first and most important steps in the reprocessing of your endoscope. Without thorough cleaning and rinsing, it might not be possible to achieve high-level disinfection. Cleaning is the removal of all adherent visible soil (i.e. blood, protein substances and other debris) from the surface, crevices and joints of the endoscope. Use caution when cleaning and disinfecting your endoscope; some methods may be harmful to the endoscope and could result in extensive damage. Manual cleaning is the recommended method for cleaning your precision endoscope. To be effective, cleaning agents must assist in the removal of residual organic debris without damaging the device. No single cleaning agent removes all types of debris or is safe to use with every type of reusable device. Certain cleaning agents may damage the device’s materials. Cleaning agents should be used in the correct dilution/concentration and at the correct temperature in accordance with the cleaning agent manufacturer’s directions. Please contact Optim LLC’s Service Center at 1.800.225.7486 or 1.508.347.5100 to verify the compatibility of a cleaning method not listed in this manual. The Optim Nasopharyngoscope is a “semi-critical” device, as defined by the Centers for Disease Control, and requires high-level disinfection or sterilization (CDC Guidelines for the Prevention and Control of Nosocomial Infections - Guidelines for Hand washing and Hospital Environmental Control, 1985. Section 2: Cleaning, disinfecting, and sterilizing patient-care equipment). WARNING: Remove the Vent Cap during immersion in cleaning and disinfecting solutions.

II- Endoscope Reprocessing Protocol: 1. 2. 3. 4.

Pre-Cleaning Leak-Testing Enzymatic Cleaning and Rinsing High-Level Disinfection with 0.55% ortho-Phthalaldehyde Solution

Pre-Cleaning: Optim recommends the endoscope be pre-cleaned immediately after every patient procedure. This will prevent patient material from adhering to the endoscope. Dried material is difficult to remove and can render the disinfection or sterilization process ineffective. Gently wipe all debris from the Insertion Tube and Distal Tip using a soft, lint-free cloth and water to which you have added a low sudsing detergent, diluted in accordance with the detergent manufacturer’s instructions.

Leak Testing: After every procedure, in preparation for high-level disinfection or sterilization, the endoscope should first be tested to ensure that it is watertight. This is accomplished using the Leak Tester. Gloves should be worn when performing the Leak Test procedure, as the endoscope has not yet been reprocessed. • •

• • • •

Remove Vent Cap. Connect the Leak Tester to the Vent by aligning the pin in the Leak Tester connector with the groove on the Vent, pushing down, and rotating the Leak Tester connector clockwise 1/4 turn. Pump the hand bulb of the Leak Tester until the needle is within the green gauge area (140180mmHg). Do not exceed 180mmHg (below red line). Observe the needle for 10 seconds. If the needle drops, the Leak Tester connection to the endoscope may be loose. Repeat procedure to verify. If the needle drops again, the endoscope may have a damaged seal and should not be immersed in any liquid. DO NOT CONTINUE TO USE THE ENDOSCOPE. Please contact Optim LLC’s Service Center at 1.800.225.7486 or 1.508.347.5100 to arrange for evaluation and/or repair. If the needle stays in place, immerse the entire endoscope in water. Observe the endoscope for 30 seconds. Articulate the Distal Bending Section up and down during this period; holes in the soft covering of the Distal Bending Section may not be evident in a relaxed position. A STEADY STREAM OF AIR BUBBLES INDICATES A LEAK IN THE ENDOSCOPE. Remove the scope immediately from the water, while the scope is still pressurized. Air escaping the endoscope at the leak site will have prevented fluid invasion. If a leak is detected, the endoscope should not be immersed in solution or used for patient procedures after the leak test. DO NOT CONTINUE USE OF THE ENDOSCOPE. Reprocess the endoscope by washing all its external surfaces with an enzymatic cleaning solution. Do not immerse the endoscope in the enzymatic cleaning solution. Do not conduct high-level disinfection or sterilization of the endoscope. Please contact Optim LLC’s Service Center at 1.800.225.7486 or 1.508.347.5100 to arrange for evaluation and/or repair. CAUTION: Do not mistake the release of trapped air from the crevices on the endoscope’s outer surface with a leak. Trapped air can be released by tapping the endoscope gently after immersing the endoscope in water.

•

Absence of a steady stream of air bubbles confirms that the endoscope is watertight. Remove the endoscope from the water and disconnect the Leak Tester from the endoscope. It is now safe to immerse the endoscope in solution.

13

Enzymatic Cleaning and Rinsing 1. Fill a basin with a freshly made solution of water and a low sudsing detergent, diluted in accordance with the detergent manufacturer’s instructions. 2. Immerse the endoscope. Wash all debris from the exterior of the endoscope by gently brushing and wiping the instrument while submerged in the detergent solution. 3. Rinse the endoscope in clean water. 4. Wipe dry the exterior of the endoscope with a soft, clean cloth.

High-Level Disinfection with 0.55% ortho-Phthalaldehyde Solution: 1. Verify that the Vent Cap is removed. 2. Prepare the disinfectant solution in accordance with the solution manufacturer’s label. 3. Completely immerse the endoscope in the disinfectant solution for the recommended time and temperature as indicated on the label of the disinfectant. 4. Thoroughly rinse the exterior of the endoscope with large amounts of clean water. NOTE: “It is suggested that all rinsing after disinfection should be done with water that has been filtered by passage through a 0.2 micron filter or otherwise treated by a method documented to improve the microbiological quality of water.” ASTM F 1518 5. A final rinse using 70% isopropyl alcohol solution can be used to speed the drying process and reduce the numbers of any organisms present as a result of rinsing with potable water. 6. Dry the exterior of the endoscope with a soft, clean towel. 7. Ensure the Eyepiece and Distal Tip lenses are free from solution residue.

III - Endoscope Storage • • • • •

The endoscope should be stored in a dry, well-ventilated environment. Avoid extreme temperatures, direct sunlight, and high humidity. Avoid storing the endoscope in areas of heavy traffic where the endoscope may sustain physical damage. Do not store the endoscope in the carrying case. The carrying case is not sufficiently ventilated for storage of the endoscope. The carrying case is intended only for transport of the endoscope. The endoscope should be completely clean and dry before storing. When storing the endoscope, be sure to keep the Insertion Tube straight.
