Cambridge Hospitals Trust has launched an appeal for missing hospital equipment.
It comes after 14 syringe pumps, which are used to administer drugs to patients have not been returned.
Each syringe costs about £1,000, though they have no street value. Now, staff are reminding patients to hand them back in when they are no longer needed.
Deputy chief nurse, Giles Thorpe, said: “We deploy a large number of these pumps every year and most are returned without an issue. However, despite trying to trace them by our normal means, 14 are still outstanding.”
The trust has offered to arrange free collections to anyone who has pumps outstanding.
