MiniMed™ 640G insulin pump

Monday, 19 November 2018

There have been reports of the MiniMed™ 640G insulin pump with version 4.10 software having failed to make expected audio sounds during alerts, alarms, or sirens.

This failure could either cause the alarm volume to be stuck at a 4 (out of 5) level regardless of your personal setting, or it could make no sound. Either of these occurrences could cause you to miss system notifications, alarms or sirens associated with how the pump is working, and with high and low glucose alerts.

Medtronic is  notifying all patients who may have one of the potentially affected insulin pumps via email and/or letter with information specific to the insulin pump model they are using.

Medtronic is advising  people to enable the Vibrate feature on their pump and  ensure remains enabled with every set change. Even if the Audio Beep test passes, the Vibrate feature should be enabled (in addition to the Audio feature) since it will add an additional notification to any alerts or alarms received on the pump. The steps for setting up the Vibrate function will be in the letter sent by Medtonic.

They are also recommending an Audio Beep test be performed to see if the pump is experiencing this potential issue. This test will identify if the pump audio is working. The steps for this test will be in the letter sent to you and are also available on the Medtronic website

Important note: This test should be repeated with every set change and once mid-way through the infusion set use to verify the continued audio functionality of the pump.
