  • Must stop pump to change cartridge


Unique AdvantagesPotential 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
