Deadlines for actions

Actions underway: 27 April 2018

Actions complete: 25 June 2018

Medical Device Safety Officers (in England)

  • ask the manufacturer to add you to their distribution list for field safety notices (FSNs). This is to help with reconciliation.


  • if your organisation receives an FSN from a manufacturer, always act on it. Do not wait for a communication from MHRA.


The manufacturer has identified that there can be a +/- 2mm overall size difference between battery brands used with CME’s T34 ambulatory syringe pumps.

This could result in battery movement within the battery housing leading to a possible loss of connection. This may result in the pump shutting down.

Be aware that if the pump’s battery connectors and/or housing are inadvertently damaged during these checks, and the pump is outside of the warranty period, the manufacturer may charge for pump repair/replacement.
