1. A glucose monitoring apparatus, comprising:

  • a measurement module havinga measurement module housing,a test strip receptacle formed at a first end of the of the measurement module housing,electronics for determining the amount of glucose present in a sample of blood placed on a test strip that is received in the test strip receptacle,a connector portion at a second end of the measurement module, andan isolated power module disposed within the measurement module;

    a processing device having a housing, wherein the measurement module is detachably integrated with and protrudes from the housing of the processing device, and wherein the measurement module housing is narrowed at the first end compared with the second end;

    a power isolation barrier between the measurement module and the processing device; and

    a transformer-coupled power transfer circuit that bridges the power isolation barrier and thereby transfers isolated power from a power source in the processing device to the isolated power module in the measurement module;

    wherein the processing device comprises a processor and computer readable medium comprising instructions when executed by the processor, cause the processor to;

    measure glucose data of a sample applied to a glucose test strip inserted into the glucose test strip receptacle using instructions residing on the computer readable medium of the processing device,provide a sensory output of a glucose level corresponding to the measured glucose data using a code residing on the processing device,enter the measured glucose data into a database accessible by a diabetes management software program stored on the computer readable medium of the processing device, andexecute the diabetes management software program whether or not the measurement module is integrated with the processing device.
