Brushing and Flushing the Channels Next, brush the inside of the endoscope channels and ports. The brush bristles should align to the diameter of the channel and should touch the wall of the channel without folding or bending during cleaning. The proper length ensures the brush will pass completely through the endoscope’s channel. The correct method to brush the endoscope channels is as follows. 1. Always brush the channels while they are submerged in the enzymatic solution to avoid any contamination caused by aerosolization. 2. Always advance the brush completely through the channels past the distal end of the endoscope. Swish the brush bristles in the cleaning solution and then reverse the direction of the brush completely back through the channels. Make sure the brush advances through the channels without kinking or bending. 3. Use the proper-sized brush to clean all valves and ports. 4. Use a disposable brush if available. If using a reusable brush, ensure that the brush is routinely cleaned and disinfected. The brush bristles should be intact and not bent or broken, and the brush shaft should be straight with no kinks or broken edges (see Figure 13). Figure 13 – Fit the Brush Bristles to the Channel

After the channels are brushed and while the endoscope is submerged in the enzymatic detergent solution, flush the channels with a pressure device (syringe or pistol) that will push the enzymatic solution through the channels (see Figure 14). Wash the outside of the endoscope with a soft cloth and brush the levers and stopcocks with a soft nylon brush.
