A medical needle shield apparatus (100) is disclosed. The medical needle shield apparatus (100) has a first cylinder, such as, for example, a shield (102) that is extensible from a retracted position to an extended position for enclosing a distal end of a needle (104) of a medical needle device. The shield includes a collar (108) that is mounted to the medical needle device. The shield further includes a proximal portion (110) extending from the collar and a distal portion (112) extending from the proximal portion. The distal portion is configured to enclose the distal end of the needle in the extended position. The proximal portion includes an engagement surface (114) that is engageable to urge the shield from the retracted position to the extended position. The collar includes a guard (116) extending therefrom and is disposed adjacent to the distal portion of the shield in the retracted position such that inadvertent extension of the shield, via engagement of the distal portion, is prevented. Two interlocks are also included to prevent inadvertent movement of the shield in the proximal and axial direction. |
