Prolonged high blood sugar; i have type 1 diabetes.
I have a medtronic minimed insulin pump, model 670g.
I have to order minimed quick-set infusion sets to use the pump.
With the last 2 boxes that i have ordered (ordered product #mmt-387a, minimed¿ quickset ¿ 6mm cannula/32" tubing on (b)(6) 2021; ordered product #mmt-398a, minimed¿ quick-set¿ 6mm cannula/43" tubing on (b)(6) 2021), i have experienced blockages in the infusion site with 40% of the infusion sets (4 out of each box of 10).
The blockages rendered the set useless, as the pump was delivering 0 insulin.
I have reported the incidents to medtronic both times and received replacement infusion sets in one of the instances.
I will be receiving the replacements for the second instance this week.
With the replacement infusion sets that i received, one set had a blockage.
Because so many of the sets don't work, in both instances i was unprepared with no sets at all and had to discontinue pump use for up to 3 days until i received the replacements.
I use syringes as a backup method.
Using syringes makes my blood sugar much harder to control.
My blood sugar normally ranges from 90 to 140.
When i only use syringes, it has been running from 150-400.
The prolonged high blood sugars mean i have symptoms of lethargy, nausea, and muscle weakness.
I have managed to avoid more serious illness like hospitalization or coma, but the possibility of these is much higher without a reliable insulin delivery method.
An elevated a1c also contributes in the long-term to kidney disease, heart disease, and nerve damage.
Fda safety report id # (b)(4).
