Seldinger safety shield for medical needles

A medical needle shield apparatus comprising:

• a needle hub supporting a needle having a distal end;
• a pair of arms extending from the needle hub and being spaced apart to define a cavity;
• and
• a shield having a plurality of hingedly connected segments being movable between a retracted position and an extended position, the shield including a proximal segment connected to the needle hub and separately connected with the arms, the proximal segment being disposable in the cavity and movable relative to the needle hub and the arms,
• the shield further including at least one intermediate segment being disposed between the proximal segment and a distal segment,
• wherein the distal segment includes a latch that engages a catch of the at least one intermediate segment in a configuration that locks the shield in the extended position.

A medical needle shield apparatus comprising:

• a needle hub supporting a needle having a distal end;
• and
• a shield being extensible between a refracted position and an extended position, the shield including a proximal portion, an intermediate portion and a distal portion,
• the proximal portion including a pair of spaced apart arms extending from the needle hub and a proximal segment extending from the needle hub and separately fixed with the arms,
• the intermediate portion including a first intermediate segment hingedly connected to the proximal segment and a second intermediate segment hingedly connected to the first intermediate segment, the first intermediate segment including a guide that is configured to engage the needle to facilitate extension of the shield between the refracted position and the extended position, and
• the distal portion including a distal segment having a bearing configured to engage the needle and facilitate extension of the shield along the needle,
• wherein the distal segment engages the proximal portion in a configuration that retains the shield in the retracted position and the distal segment includes a distal end surface configured to engage the distal end of the needle when the shield is in the extended position to prevent displacement of the shield from the extended position.
