The insulin delivery was noticeably different than another fda approved insulin delivery system.We have seen what we believe are two problems with the omnipod system on a somewhat regular basis.When we first attach and start a new pump, our daughter will go through a period of 4-8 hours where her blood sugar is high.Later, near the end of the 2-3 day life of a pump, we will see the same behavior again.She will have consistently high blood sugar levels that just do not seem to respond to insulin in the same way that they did in the midlife (12-48 hours) of the pump.We have performed an unofficial experiment that backs up our claim with some data.We used our previous insulin delivery system, a novolog insulin pen, to deliver 5 units into a cap that covers the needle that works with that pen.We then took an omnipod pod which we felt was not working near the end of its life (48-72 hours), which we had detached from our daughter without deactivating, and had it deliver 5 units into an identical cap.We put the two caps side by side and compared the levels.We did this test on two different occasions and each time the omnipod system delivered noticeably less insulin.This is consistent with our belief that the omnipod system delivers inconsistent amounts of insulin over its approved 72 hours of use.We have included copies of the pictures we have taken.Frequent high and subsequent low blood sugar levels.
