I was wearing a minimed paradigm revel insulin pump.Shortly after lunch, my blood sugar started to rise extremely rapidly and continued to rise over several hours, despite administering multiple insulin boluses.I went to change the infusion set (paradigm quick-set), thinking the cannula was bent.I discovered the tubing was sliced in half.The tubing did not come in contact with anything sharp while i was wearing it.It appears a cut was introduced in the tubing during the mfg process and tubing became fully separated during normal use.Other infusion sets in the package were not impacted.Fortunately, i was able to get my blood sugar, which had risen over 400, back under control with an insulin injection and replacement of infusion set.Fda safety report id# (b)(4).
