Insulin Flow Blocked


1. Check BG. Consider injection and testing ketones. Change reservoir and infusion set.

What has happened: Your pump has detected that the basal or bolus insulin flow was blocked.

Next steps:

  • Check your blood glucose. Consider checking ketones and take an injection if needed
  • Remove your infusion set and reservoir
  • Select Rewind to start the new reservoir process using a new infusion set and reservoir

If a bolus delivery was in progress when the alarm occurred:

  • Check the Daily History screen for the amount of bolus already delivered before the pump alarmed
  • Consider delivering remaining bolus, if the bolus insulin was not included in an insulin injection

2. Check BG. Consider injection and testing ketones. Estimated 0 U insulin in reservoir. Change reservoir and infusion set.

What has happened: Your pump has detected that the insulin flow was blocked and there is no insulin in the reservoir.

Next steps:

  • Check your blood glucose. Consider checking ketones and take an injection if needed
  • Remove your infusion set and reservoir
  • Select Rewind to start the new reservoir process using a new infusion set and reservoir

If a bolus delivery was in progress when the alarm occurred:

  • Check the Daily History screen for the amount of bolus already delivered before the pump alarmed
  • Consider delivering remaining bolus, if the bolus insulin was not included in an insulin injection

3. Fill Cannula stopped. Remove infusion set from body. Change reservoir and infusion set.

What has happened: Your pump has detected the insulin flow was blocked while filling the cannula.

Next steps:

  • Check your blood glucose. Consider checking ketones and take an injection if needed
  • Remove your infusion set and reservoir
  • Select Rewind to start the new reservoir process using a new infusion set and reservoir

If a fill cannula was in progress when the alarm occurred:

  • Check the Daily History screen for the amount of bolus already delivered before the pump alarmed
  • Consider delivering remaining bolus, if the bolus insulin was not included in an insulin injection

4. Fill Tubing stopped. Remove reservoir and select Rewind to restart.

What has happened: Your pump has detected the insulin flow was blocked while filling the tubing. Possible connection issue between the tubing and reservoir.

Next steps:

  • Remove the reservoir and select Rewind to restart the fill tubing process
  • Disconnect tubing from reservoir. Be sure tubing is not crimped or bent
  • Continue following the steps displayed on the pump using the same infusion set and reservoir
  • If this alarm occurs again, use a new infusion set

If a fill tubing delivery was in progress when the alarm occurred:

  • Check the Daily History screen for the amount of bolus already delivered before the pump alarmed
  • Consider delivering remaining bolus, if the bolus insulin was not included in an insulin injection
