FIELD: medical equipment.
SUBSTANCE: invention relates to medical equipment, namely to devices for blood collection with a concealed needle. The device contains needle cannula (28), sleeve (44) serving as a support for the needle cannula, and tip protection (24) axially moved along the needle cannula, while, after transfer, tip protection embraces with concealment distal end (42) of the needle cannula. The needle device includes a pair of wings (60) extending transversely from opposite sides of tip protection and connected to the sleeve. The pair of wings is transferable between the first position and the second position, while transfer of the pair of wings retracts tip protection from a proximal position to a concealing distal position. Wings include protrusions (66), which force the longitudinal axis of the needle cannula to offset from hole (52) of tip protection during retraction of tip protection, which prevents repeated insertion of the needle cannula through tip protection after tip protection is transferred to the distal position.
EFFECT: obtainment of a blood collection device.
