ABSTRACT:
A medical needle shield apparatus is provided that includes a needle hub having a needle cannula extending therefrom. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the needle. The shield includes a binding member disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the inner needle. The binding member includes at least one drag inducing member that engages the inner needle during slidable receipt to create a drag force. The drag force facilitates rotation of the binding member such that the binding surfaces engage the inner needle to prevent slidable movement. The shield and/or hub includes a retention element engageable between the shield and hub and a sheath retention element. The hub includes a magnifier for viewing fluid flashback.
