Welcome 

This course provides a comprehensive approach to cleaning the inside and outside of endoscopes, emphasizing proper techniques, safety protocols, and best practices to ensure cleanliness and device longevity.
Proper cleaning is critical for several reasons. It prevents infection, maintains the integrity of the instrument, and ensures that it functions as it should for future procedures.

• Endoscopes come into contact with bodily fluids, tissue, and other bio-contaminants during use.
• Failure to clean them properly can lead to infection transmission, costly repairs, and damage to the endoscope.

To clean an endoscope thoroughly, we must focus on both the outside and inside components.

• External Surfaces: Include the insertion tube, control body, umbilical cord, and buttons.
• Internal Channels: Such as suction, biopsy, air/water, and working channels.
• Distal Tip & Light Guide: These require special care because they are delicate and prone to contamination.

Pre-cleaning should begin immediately after use, before transporting the endoscope for full cleaning.
Steps: 

1. Immediate Rinsing:
   Wipe the outside of the endoscope with a soft cloth or sponge to remove gross contaminants.
2. Careful Handling:
   Be mindful to prevent kinks or damage while cleaning.

Let’s dive into cleaning the external surfaces.

Steps: 

1. Step 1: Leak Testing
   Perform a leak test to ensure no damage before immersing the endoscope in cleaning solutions.
2. Step 2: External Wipe Down
   Use an enzymatic detergent and a lint-free cloth or cleaning sponge like the Spec Clean™ Endoscope Sponge to clean the insertion tube and handle.
3. Step 3: Control Head and Buttons
   Gently scrub around the control buttons and handle with a soft brush to remove residue.
4. Step 4: Rinse
   Rinse the external surfaces with clean water to remove the detergent.

Now, we’ll focus on cleaning the internal channels, which is a crucial part of ensuring no contaminants remain inside.

Steps:

1. Step 1: Manual Brushing
   Insert a channel brush designed for endoscopes into the air/water, suction, and biopsy channels. Move the brush back and forth to dislodge debris.
2. Step 2: Flushing the Channels
   Flush each channel with an enzymatic cleaning solution using a syringe or flushing device. 
3. Step 3: Suction Channel Cleaning
   Draw cleaning solution through the suction channel and rinse thoroughly to remove debris.
4. Step 4: Cleaning the Distal Tip & Light Guide
   Use a small brush to gently clean these delicate parts.

After brushing and flushing, we need to ensure that all channels are properly rinsed and dried.
Steps:

1. Rinse Channels:
   Flush with sterile water to remove any remaining cleaning solution.
2. Inspect:
   Use a borescope to visually inspect the endoscope’s channels for cleanliness.

Proper drying and storage are just as important as cleaning.

Steps:

1. Ensure that the endoscope is completely dry before storage to prevent microbial growth.
2. Use air or a drying pump to ensure the channels are moisture-free.
3. Store the endoscope in a well-ventilated, clean cabinet.
