From Lexicanum

A medi-pack is a device used by the Imperial Guard to help patch up wounded soldiers on the battlefield. It is taken by medics in the command squad. It is sometimes also known as a Narthecium and is commonly in use in command squads rather than in units of standard guardsman. The design of the medi-pack can range from a small medical kit to a complex scanning devices depending on the original source of the regiment and the planet's technological base
