Safety shield for medical needles

摘要

A medical needle shield apparatus is provided that includes a shield being extensible from a retracted position to an extended position, wherein the shield includes a first segment mounted to a medical needle device having a needle extending therefrom. The shield further includes a second segment articulating from the first segment and a third segment articulating from the first segment, wherein the second segment includes an engagement surface. The shield further includes a fourth segment articulating from the second segment and the third segment. The engagement surface of the second segment is engageable to urge the shield from the retracted position such that the second segment and the third segment cooperate to extend the shield to the extended position, whereby the fourth segment substantially encloses a distal end of the needle.
