Safety syringe

A safety syringe comprising a hollow barrel, a plug, a needle hub, a plunger and a cord;

• the hollow barrel being cylindrical and having
• a distal open end;
• a proximal open end;
• an inside surface;
• an outside surface;
• an annular flange formed radially around extending out from the distal open end;
• a lip formed radially around and extending inward from the proximal open end of the hollow barrel;
• a proximal annular rib defined inside the hollow barrel near the lip and
• a central annular rib defined inside the hollow barrel;
• the plug detachably engaged with the proximal annular rib inside the proximal open end of the hollow barrel and having
• a top surface;
• a bottom surface;
• a hub recess being tapered and defined through the plug from the top surface to the bottom surface;
• and
• a needle hole defined through the plug;
• the needle hub mounted in the plug and having
• a connecting tube being tapered and having a distal end and a proximal end;
• and
• a needle attached to the proximal end of the connecting tube and having a central passage;
• the plunger having
• a push rod being mounted inside the hollow barrel and having
• a proximal end;
• and
• a seal having
• a top surface attached to the proximal end of the push rod;
• and
• a bottom surface;
• and
• the cord connected between the plug and the plunger and having
• a top end attached to the bottom surface of the seal;
• and
• a bottom end attached to the top surface of the plug;
• wherein a distance between the proximal end of the hollow barrel and the central annular rib is greater than a combined length of the needle hub and the plug.
