Insulin dispenser

Apparatus for administering an injection, comprising;

• a body;
• first and second fluid storage chambers extending within said body;
• first and second fluids located within respective ones of said first and second fluid storage chambers;
• a fluid accumulator extending within said body and communicating with said first and second fluid storage chambers;
• first and second plungers moving through respective ones of said first and second fluid storage chambers to cause at least some of said first and second fluids to be delivered from said first and second fluid storage chambers to said fluid accumulator;
• a hypodermic needle to be connected in fluid communication with said fluid accumulator for injecting said first and second fluids delivered to said fluid accumulator into living tissue;
• an accumulator plunger moving through said fluid accumulator so as to cause said first and second fluids to be supplied from said fluid accumulator to said hypodermic needle;
• and
• means by which move said hypodermic needle relative to said body between a retracted position inwardly of said body and an axially advanced position outwardly of said body at which to administer the injection.

A fluid medication dispenser, comprising:

• a housing having an interior and an exterior;
• first and second fluid storage chambers extending within the interior of said housing;
• first and second fluid medications located within respective ones of said first and second fluid storage chambers;
• a fluid accumulator extending within the interior of said housing;
• valve means by which to place said first and second fluid storage chambers in fluid communication with said fluid accumulator;
• plunger means adapted to be positioned within and moved through said first and second fluid storage chambers to cause at least some of said first and second fluid medications to be delivered from said first and second fluid storage chambers to said fluid accumulator via said valve means;
• a hypodermic needle located at a retracted and shielded position at the exterior of said housing so as to lie out of fluid communication with said fluid accumulator;
• a fluid transfer port extending through said housing between the interior and the exterior thereof, said fluid transfer port communicating with said fluid accumulator;
• means to slide said hypodermic needle in an axial direction along the exterior of said housing between said retracted and shielded position and an axially extended and exposed position so that said hypodermic needle is aligned with said fluid transfer port to communicate with said fluid accumulator;
• and
• means by which to cause said first and second fluid medications to be supplied from said fluid accumulator at the interior of said housing to said hypodermic needle at the exterior of said housing by way of said fluid transfer port extending therebetween so that an injection of said first and second fluid medications can be administered to living tissue with said hypodermic needle in the axially extended and exposed position.
