Specific Hudson RCI Sheridan endotracheal tubes and connectors - 15 mm connector may detach from the tube before or during use (MDA/2019/036)

Manufactured by Teleflex Medical – disconnection can result in inadequate oxygenation and ventilation requiring medical intervention to avoid hypoxia, severe neurological injury or death.


The manufacturer initially issued a Field Safety Notice (FSN) highlighting this issue in May 2019, but an updated version was circulated in August 2019 expanding the range of affected devices.

  • Identify and quarantine affected devices in stock (see Appendix 2 of the FSN dated 6 August 2019).
  • For devices currently in use, follow the guidance in the FSN.
  • Complete the ‘Field Safety Corrective Action Acknowledgement Form’ in Appendix 1 of the FSN even if you don’t have affected devices left in stock, and return it to orders.uk@teleflex.com to arrange return of affected devices.
  • Even if you completed the acknowledgement form in the earlier version of the FSN, you need to also complete the one in the updated FSN.
  • Report suspected or actual adverse events involving these devices through your local incident reporting system and/or your national incident reporting authority as appropriate: England, Scotland, Northern Ireland, Wales. You should also report directly to manufacturers if your local or national systems do not.
