    摘要: A catheter and introducer needle assembly with a needle shield is provided. The needle shield includes a means for preventing unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a means for connecting the needle shield to the catheter hub until the sharp distal tip of the introducer needle has been withdrawn into the needle shield. Thus, when the distal end of the introducer needle extends from the distal portion of the needle shield, the needle shield is connected to the catheter hub and when the sharp distal end of the introducer needle is withdrawn into the needle shield, the needle shield is disconnected from the catheter hub. At that point, the sharp needle tip is secured within the needle shield.

    摘要: An apparatus to automatically secure an end of a needle after contact with a blood vessel. The apparatus may include a housing and a biasing member, where the housing includes a hollow interior region extending between a proximal end and a distal end thereof. A proximal opening may be integrated into the proximal end, while a distal opening may be integrated into the distal end. The proximal and distal openings may be configured to receive a needle therethrough along a longitudinal axis. The biasing member may be coupled to the housing and configured to apply a force to the needle. The force may be oriented to displace the needle relative to the longitudinal axis upon retracting an end of the needle through the distal opening into the hollow interior region. Embodiments of the present invention may thus secure the end of the needle within the hollow interior region after use to prevent accidental needle sticks and exposure to blood and blood-borne pathogens.
