Device details

Accu-Chek® Insight insulin pumps MDA/2015/029!


Roche has identified that the use of low-quality batteries or users incorrectly confirming the battery type in the pump settings can lead to unexpected rapid power depletion or a shutdown of the pump. If this goes undetected, patients could experience hyperglycaemia due to under delivery of insulin.

Roche has provided updated handling instructions and battery model recommendations in their FSN issued in June 2015 (manufacturer’s reference: SB_RDC_2015_04) but has not had enough replies to know that healthcare providers and users have received and acted on this advice.
