1. A system for administering a medicine to a patient, comprising:

  • an injection pen device, comprising;

    a housing including a main body structured to include a chamber to encase a cartridge containing medicine when the cartridge is loaded in the chamber,a dose setting and dispensing mechanism to set and dispense a particular dose of the medicine from the loaded cartridge, the dose setting and dispensing mechanism including a dose knob, a shaft, and a piston assembly including a plunger, wherein the dose knob is rotatable to cause the shaft to move to a position proportional to a set dose of the medicine, and wherein the dose knob is moveable to cause the shaft to drive the plunger to dispense the medicine from the cartridge,a sensor unit to detect a dispensed dose based on one or both of positions or movements of the dose setting and dispensing mechanism, wherein the dispensed dose includes an amount of medicine dispensed from the cartridge, andan electronics unit in communication with the sensor unit, the electronics unit including a processing unit including a processor and a non-transitory memory to process the detected dispensed dose and time data associated with a dispensing event to generate dose data, a transmitter to wirelessly transmit the dose data to a user device, and a power source to provide electrical power to the electronics unit; and

    a mobile communication device in wireless communication with the injection pen, wherein the mobile communication device includes a data processing unit including a processor to process the dose data and a memory to store or buffer the dose data, a display to present a user interface, and a wireless communications unit to wirelessly receive the dose data from the injection pen device, wherein the data processing unit includes a software application program product stored in the memory of the data processing unit of the mobile communication device and having instructions stored thereon and operable to cause the mobile communication device to perform operations, comprising;

    processing one or more dose data corresponding to one or more dispensing events over a predetermined duration of time to form a dose dispensing sequence; and

    determining a type of dispensing event as a priming event or an injection event for the one or more dose data in the dose dispensing sequence that includes detecting a rate at which the medicine is dispensed for each dispensing event, and upon a determination that the rate at which the medicine is dispensed is slower than a predetermined dispensing rate threshold, identifying the dispensing event as the priming event, and upon a determination that the dispensed rate is faster than the predetermined dispensing rate threshold, identifying the dispensing event as the injection event.
