A Needleless injector patch for the intramuscular, subcutaneous, or intra-dermal delivery of a fluid medicament to a patient includes a plurality of cylindrical members "Micro-Injectors" which have a closed end and an sealed orifice end, the Micro-Jects contain a pyrotechnic charge, a piston and a quantity of medication. An onboard microprocessor programmatically selects the time to initiate a Micro-Ject unit by applying current to the pyrotechnic charge generating a volume of gas which pushes a piston pressurizing the medication to the point that a rupture element bursts allowing the medication to be expelled as a fine stream at high pressure that pierces the epidermis to a controlled depth delivering the medication as an injection.
