3.6.4 Inspecting the Air/Water and Instrument Channels
(1) Turn on the suction unit, cart, processor and light source.
Keep the lamp off.
(2) Prepare a clean basin of sterile water.
(3) Place the distal end of the ultrasonic endoscope without
touching the floor, etc., depress the air/water valve
halfway, and check that sterile water comes out of the
nozzle.
[Note]
Mind the direction in which sterile water comes out since
it may splash.
(4) With the distal end of the ultrasonic endoscope held in the
air, press the air/water valve completely. Check that water
is discharged from the balloon water port.
[Note]
Mind the direction in which sterile water comes out since
it may splash.
(5) Immerse the distal end of the ultrasonic endoscope in
water, cover the hole at the center of the air/water valve
with your finger, and then check that air comes out of the
nozzle.
Release the finger from the hole and check that air does
not come out of the nozzle.
