Here is a bubble diagram that represents the state machine requirements in its simpliest form. For a more descriptive version, see How will states and modes be used to control an insulin pump?

Generic state diagram for artificial pancreas modeling

The state names correspond as follows:

  • S1: Deliver Basal Insulin Closed Loop
  • S2: Deliver Pre-Bolus
  • S3: Evaluate Pre-Bolus
  • S4: Deliver Correction Bolus
  • S5: Evaluate Correction Bolus
  • S6: Deliver Missed Bolus
  • S7: Evaluate Adaptive Bolus
  • S8: Deliver Basal Insulin Open Loop
  • S9: Emergency Halt
