Zusammenfassung:	A needle assembly (10), comprising a needle (16) defining a needle lumen; a first notch (83) defined in a side wall of the needle (16) to enable blood to pass therethrough from the needle lumen when an open distal tip (16B) of the needle is disposed in a blood-carrying vessel of a patient; and a flash indicator (80) configured to indicate the presence of blood within the needle lumen, the flash indicator (80) including a translucent flash chamber (82) disposed about the needle (16) so as to enclose the first notch (83) and configured such that blood present in the needle lumen passes from the needle lumen via the first notch (83) to the flash chamber (82) so as to be observable to a user of the needle assembly.
