1. A medical needle shield apparatus comprising:

  • a shield being extensible from a retracted position to an extended position to enclose a distal end of a needle;

    a binding member disposed within the shield and defining binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position, the binding member including one or more drag inducing members that engage the needle during slidable receipt of the needle to create a drag force with the needle, the drag force and shield facilitating rotation of the binding member relative to a longitudinal axis of the needle such that the binding surfaces engage the needle to prevent slidable movement of the needle in the extended position of the shield, the binding member further including a retainer extending therefrom such that the retainer is engageable with the needle to prevent rotation of the binding member prior to the extended position; and

    a hub retainer being configured to engage a catheter hub.
