Filling Your Reservoir
Device: 754 (VEOTM), 722, 715, 712
Important: Using cold insulin can cause air bubbles in the reservoir and tubing. If your insulin is stored in the refrigerator, allow it to reach room temperature before filling your reservoir. When filling the reservoir, take care to remove air bubbles.
- Remove reservoir from package. Make sure plunger rod is fully extended.
- Swab the top of the insulin vial with alcohol. Press the transfer guard onto the top of the insulin vial until it snaps into place (make sure you do not push down on the plunger during this step)
- Push and hold the plunger rod down to pressurize the vial.
- Continue to hold the plunger rod as you turn the vial over (the vial should now be on top and the reservoir on the bottom). Slowly pull the plunger rod down to fill the reservoir with insulin.
- Gently tap the side of the reservoir to make any air bubbles rise to the top of the reservoir.
- Slowly push up on the plunger rod just enough to remove any air bubbles from the reservoir.
- When all air bubbles are removed, slowly pull the plunger rod down to fill the reservoir with the number of units needed for the next 2 or 3 days.
- Now turn the vial and reservoir over again (the insulin vial should now be on the bottom and the reservoir on top). Hold the transfer guard with one hand as you turn the reservoir counter-clockwise, and pull up on the reservoir to remove it from the transfer guard.
- Hold the infusion set tubing connector in one hand and the reservoir in the other. Place the connector onto the top of the reservoir and turn the connector clockwise as you press it gently against the reservoir, until it slides into place. Push in on the connector and continue to turn until the reservoir and connector lock with a click.
- Tap the side of the reservoir to make any air bubbles that may still be in the reservoir rise to the top. Push up on the plunger rod until all of the air is out and you see a small amount of insulin in the tubing.
- Holding the reservoir (in one hand), gently turn the plunger rod counter-clockwise (with the other hand), until it unscrews from the reservoir. Be careful not to pull down on the plunger as you unscrew the plunger rod. Avoid squeezing the O-rings as you do so.
Important: Use your reservoir right after you fill it. Do not store it filled.
