I inserted a infusion set for my insulin pump.I noticed that my blood glucose was trending up over 300mg/dl.I kept bolusing in an attempt to get bg down.It did not work.Then i looked at the infusion set.The tape was wet.I discovered that the insulin was leaking out of the site under the tape and not going into my body through the plastic cannula.I changed sites.My bg came down.A few hours later i was once again began having bg over 300mg/dl.This time i checked the site first.Sure enough the insulin was leaking out under the tape portion of the site.I got a new box of infusion sets and inserted a new site.Thus far i have had no failure of the site and my bg has remained under control.Clearly this lot of infusion sites was defective.In spite of this tandem encouraged me to use the lot of defective infusion sets and would only replace 2 sets - not the entire box.In my assessment this is dangerous.Fda safety report id #(b)(4).
