External infusion pump apparatus

A programmable fluid pumping apparatus comprising:

• power producing means for supplying power to said apparatus comprising:
• a first power source for supplying power to said apparatus, and
• a second power source for supplying power to a portion of said apparatus only when said first power source cannot supply adequate power to said apparatus;
• a first circuit means responsive to said power producing means for assisting said power producing means in producing necessary power levels;
• a second circuit means responsive to an output of said power producing means for generating sufficient power for driving a pump drive means;
• a third circuit means responsive to an output of said second circuit means for storing power generated by said second circuit means;
• said pump drive means being responsive to an output of said third circuit means;
• pump means mechanically connected and responsive to said pump drive means for pumping fluid from a fluid reservoir;
• a first sensing means responsive to a stored power level of said third circuit means for determining when said stored power level equals or exceeds a predetermined value;
• a second sensing means responsive to a power level of said power producing means for determining when the power level of said power producing means has dropped below a predetermined value;
• processing means responsive to and interactive with said power producing means, first circuit means, second circuit means, third circuit means, first sensing means, and second sensing means for controlling the operation of said pumping apparatus;
• a plurality of actuator means interactive with said processing means for controlling operating parameter values utilized by said processing means;
• memory means interactive with and responsive to said processing means for storing and providing said operating parameter values used by said processing means;
• and
• indicator means responsive to said processing means for providing selective indications of the operating status or condition of said apparatus.
