Safety needle device

A safety needle device, comprising:

• a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body;
• a first guide path, a second guide path and a third guide path disposed on the housing body, the second guide path intersecting the first guide path and the third guide path;
• a needle hub disposed on the proximal end of the housing;
• a needle cannula attached to the needle hub;
• a retractable sheath having a guide element configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the retractable sheath rotates with respect to the housing during movement from the initial position to the retracted position, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula, the first guide path and the second guide path disposed on the housing body configured to receive the guide element;
• a locking rib on a distal end of the retractable sheath;
• a tab on the housing;
• a metal latch disposed on the retractable sheath;
• a rotating cam disposed in the housing body;
• and
• a spring element.
