ABSTRACT:
A ratcheting needle protector assembly including a body, a needle hub and a needle. The body has a first end and a second end. The body defines a channel extending longitudinally between the first and second ends. The body defines receiving devices for receiving a pawl of a ratchet arm between the first and second ends. The needle hub has an external portion, an internal portion and a tracking member movably mounted on the body. The tracking member is positioned in the channel. The needle hub includes a ratchet arm having a pawl adapted to be received by the receiving devices. The needle is mounted on the internal portion of the needle hub. Movement of the needle hub from the first end to the second end of the body causes movement of the needle from outside the body to inside the body. The pawl of the ratchet arm is received by the receiving devices to prevent movement of the needle from inside the body.
