2. Submerge the connecting tube in a minimum of 60 ml of water
or saline.
3. Fill the inflation device with a minimum of 40 ml and a maximum
of 50 ml of fluid by depressing the I/D button while simultaneously
grasping and pulling back on the P/D knob. (See fig. 2) Release the I/D
button to lock the plunger in place.
4. To completely purge the inflation device of air, hold the Q.I.D. upright
and depress the I/D button while grasping and slowly pushing forward
on the P/D knob. (See fig. 3) Release the I/D button to lock the plunger
in position.
5. Attach the Q.I.D. connecting tube to the inflation hub of the balloon
dilator. Secure by rotating the fittings.
Note:
If use of the stopcock is
desired, attach the appropriate fittings to the balloon dilator and the
Q.I.D. connecting tube. To secure the attachment, rotate the fittings.
The arm of the stopcock indicates which port is closed.
6. Aspirate all residual air from balloon.
7. Depress the I/D button and pull back the P/D knob until the vacuum
is indicated on the pressure gauge (See fig. 4). While maintaining a
vacuum with the P/D knob, release the I/D button. Release the P/D
knob. The balloon dilator is now ready for placement through the
accessory channel of the endoscope.
INSTRUCTIONS FOR USE
Balloon Inflation
1. For rapid inflation, depress the I/D button and push the P/D knob
forward until significant resistance is met. (See fig. 5) Maintain pressure
on the P/D knob while releasing the I/D button. (See fig. 6)
2. To attain specified balloon pressure for the dilator being used, rotate
the P/D knob clockwise. Refer to the balloon dilator labeling for
recommended inflation pressure. Pressure may be decreased by
rotating the P/D knob counterclockwise.
Balloon Deflation
3. To decrease the balloon pressure and deflate the balloon, hold the
inflation device while rotating the P/D knob counterclockwise until
pressure decreases below 20 psi. Depress the I/D button and pull back
on the P/D knob, creating negative pressure as seen on the pressure
gauge. (See fig. 7) Release the I/D button to lock in negative pressure.
4. Maintain negative pressure and observe the balloon for complete
deflation. Negative pressure may be increased by continued
counterclockwise rotation of the P/D knob.
Note:
The indicator on
the pressure gauge should register in the red, vacuum portion of the
gauge during deflation.
