The invention relates to a system for extracting blood from a patient. A blood sampling device comprises a needle holder or syringe (3) supporting a hypodermic needle (1). The needle holder or syringe comprises a lever (8), either separately attachable or integrally formed, the lever having a first end (9) for being moved with a finger such that when the first end is moved, the lever pivots and its second end (11) separates the needle from the needle holder or syringe, thereby providing an easy and safe way of ejecting a used needle from the sampling device for disposal.
