Abstract
A needle assembly comprises a metal needle (1) with a hub (13) and a marker in the form of a bubble-filled plastics rod (2) inserted within the needle. The rod (2) makes the assembly more visible under ultrasound observation when confirming correct placement of the needle (1) and is subsequently removed when correct placement has been confirmed.
