ULTRASOUND GASTROVIDEOSCOPE GF-UCT180
Preparation
1.
Fill a basin with disinfectant solution at the temperature and concentration
recommended by the disinfectant manufacturer. Use a basin that is at least
40 cm by 40 cm (16” by 16”) in size and deep enough to completely
immerse the endoscope.
2. Attach the cleaning adapter for the instrument channel port to the
endoscope.
3. Attach the channel plug and the injection tube to the endoscope. Attach the
channel plug’s biopsy valve cap to the cleaning adapter for instrument
channel port (see Figures 9.17 and 9.18).
4. Attach the washing tube to the elevator channel plug (see Figure 9.20).
Flushing disinfectant solution into all channels
Completely remove all air bubbles from all channels. Air
bubbles may inhibit disinfection of the channel surface.
Removal of air bubbles can be facilitated by forcefully
injecting disinfectant solution into the channels.
1. Immerse the endoscope and all equipment in the disinfectant solution.
2. Confirm that the suction port of the injection tube is immersed in disinfectant
solution.
3. Using the 30 cm
3
(30 ml) syringe, flush at least 150 cm
3
(150 ml) of
disinfectant solution through the air/water and suction channels respectively.
Confirm that no bubbles exit the distal end of the endoscope.
4. Using the washing tube and the 5 cm
3
(5 ml) syringe, flush 15 cm
3
(15 ml)
of disinfectant solution through the elevator wire channel. Confirm that no
bubbles exit the distal end of the endoscope.
5. While immersed in disinfectant solution, raise the forceps elevator and flush
the vicinity of the forceps elevator with disinfectant solution using the 30 cm
3
(30 ml) syringe.
6. With the endoscope, channel plug, injection tube, cleaning adapter for the
instrument channel port and washing tube completely immersed in
disinfectant solution, detach all equipment from the endoscope. Leave the
endoscope and all equipment immersed in the disinfectant solution.
