Replacing your Infusion Set and Reservoir
WARNING: If insulin, or any liquid, gets inside the tubing connector, it can temporarily block the vents that allow the pump to properly prime the infusion set. This may result in the delivery of too little or too much insulin, which can cause hypoglycemia or hyperglycemia. To prevent insulin from getting inside the tubing connector of the Quick-set infusion set, after you fill the reservoir make sure you hold the insulin vial upright when you remove the reservoir from the transfer guard. If you do not hold the insulin vial upright, insulin can get on the top of the reservoir and could transfer liquid into the tubing connector. For more information, please see “Tubing Connector”, located in the Introduction chapter of the MiniMed 530G System User Guide.
Process
To Rewind the Piston in the Pump:
- Wash your hands. Remove the old infusion set from your body and the reservoir from the pump.
- Select Reservoir + Set in the MAIN MENU, then select Reservoir Setup to open the REWIND screen
To Fill the Reservoir:
- Remove the reservoir from the package
- Pull the plunger down to fill the reservoir with air.
- Wipe the top of the insulin vial with alcohol. Hold the blue transfer guard and press it down onto the insulin vial
- Push down on the plunger to push air from the reservoir into the vial. Continue to hold the plunger down
- Flip the vial over so it is now on top. Slowly pull the plunger down to fill the reservoir
- Check the reservoir for air bubbles. Tap the side of the reservoir to force any bubbles to rise to the top. Push the plunger up to move the air bubbles from the reservoir into the insulin vial
- After the air bubbles are removed, slowly pull the plunger down to fill the reservoir with enough insulin to last 2-3 days.
- To avoid getting insulin on the top of the reservoir, flip the vial over, so the vial is upright. Hold the transfer guard, and turn the reservoir counterclockwise. Pull the reservoir straight up to disconnect it from the transfer guard. Discard the transfer guard into a sharps container.
To Connect the Reservoir to the Tubing:
- Remove the Quick-set from the package.
- Make sure the top of the reservoir is dry. Gently push the tubing connector onto the top of the reservoir and turn it clockwise until it slides and locks into place
- Tap the side of the reservoir to force any remaining air bubbles to rise to the top. Push up on the plunger until the bubbles are out and you see insulin in the tubing
- Turn the plunger counter-clockwise to unscrew it from the reservoir. Be careful not to pull the plunger before it is disconnected, or insulin will spill out.
