Patent ID: 8663129

Claim:
A blood collection safety device, comprising: a housing comprising a motion regulating frame, a chamber, and a longitudinal axis; a needle comprising a proximal tip and a distal tip; a proximal needle cover comprising a ramp and configured to move relative to the housing between an engaged position and a disengaged position, the engaged position being at least partly distal of the disengaged position, the disengaged position configured such that the proximal tip of the needle is positioned distal of a portion of the proximal needle cover; a distal needle cover comprising a guiding member and configured to move relative to the housing between a retracted position and an extended position, the distal needle cover being positioned proximal of the distal tip of the needle in the retracted position, the distal needle cover being positioned distal of the distal tip of the needle in the extended position; and a locking member comprising a wing configured to engage the motion regulating frame to retain the distal needle cover in the retracted position, wherein the ramp of the proximal needle cover and the guiding member of the distal needle cover are configured to engage as the proximal needle cover is moving to the engaged position, thereby rotating the locking member relative to the motion regulating frame and releasing the distal needle cover to move distally toward the extended position.
