Medical injector

A device, comprising:

• a housing including a first substantially planar side wall and a second substantially planar sidewall, the first side wall and the second side wall collectively defining a medicament reservoir, the first side wall and the second side wall spaced apart by less than one inch;
• a plunger disposed at least partially within said medicament reservoir and movable between a first position and a second position;
• a liquid dispensing needle coupled to the plunger, the needle configured to be placed in fluid communication with said medicament reservoir, said needle contained within said housing when said plunger is in said first position, at least a portion of said needle disposed outside of the housing when said plunger is in said second position;
• and
• a spring adapted to bias said plunger.

A device comprising:

• a housing having a first substantially planar side wall and a second substantially planar sidewall, the first side wall and the second side wall collectively defining a medicament reservoir, a length of said housing approximating a length of a credit card;
• a member disposed within the medicament reservoir, said member fixedly connected to a needle, said member adapted to move a tip of said needle from a first position within said housing to a second position outside of said housing, a portion of said member in contact with a fluid medication, said member adapted to cause the fluid medication to pass through said needle when said member moves;
• and
• a spring adapted to automatically bias the needle.
