Medtronic releases a safety notification for Paradigm insulin pump users. Loose drive support caps may spur issues with insulin overdosing and resultant hypoglycemia.
They suggest customers never push in a loose support cap as it is on the bottom of the insulin reservoir compartment.
If you are a Medtronic Paradigm insulin pump user, check out the notification letter here.
Medtronic also addresses electronic issues when pumps are submerged in water. If you have jumped in the pool (only to discover your pump was still on) you will want to contact Medtronic.
