Insulet
OmniPod

 insulet-new-omnipod_large
Unique Advantages Potential Drawbacks
  • Reduced up-front costs
  • Can program through clothing from a few feet away
  • Discrete pump size (compared to other pumps)
  • No tubing (minimizes wasted insulin, no tangling/snagging, less awkward, no air pockets, no siphoning effects)
  • No disconnecting/reconnecting means no missed/lost insulin
  • Simple, automated canula insertion minimizes pain, reduces “human errors”, creates more site options
  • Forced pod change reduces chances for lipodystrophy & absorption problems
  • Pump is fully watertight
  • Temp basals and boluses can be customized/preset
  • Freestyle meter built into handheld programmer
  • Can customize programming text without PC linkup
  • Large color screen w/full-sentence text and graphing capability
  • Only 2 parts; convenient for travel
  • Somewhat bulky programmer
  • Pod creates a “bulge” on the skin
  • Cannot enter boluses or make setting changes without programmer
  • Cannot do programming or editing while bolus is delivering
  • Only one canula orientation/length; may not work for all body types
  • Max reservoir volume 200u; minimum fill amount 85u
  • Pod stops working after 72 hours (plus grace period)
  • Handheld will not calculate bolus if BG < 50
  • Dislodged/clogged canula requires complete pod replacement
  • “Disconnection” requires complete pod replacement
  • Pod does not have vibrate option
  • Must suspend when changing basal settings
  • Temp basal limited to 12 hours max
  • Not covered by all 3rd party payors
