1. A bladder monitor system comprising:

  • a pressure measurement device capable of using magnetic induction telemetry, said measurement device further capable of being removably insertable into a bladder of an animal, said measurement device comprising;

    a. a self-contained device power source;

    b. a pressure sensor;

    c. at least one offset balance resistor operatively interconnected to said pressure sensor;

    d. a differential amplifier operatively interconnected to an output portion of said pressure sensor, said differential amplifier further operatively interconnected to a discharge portion of said self-contained device power source;

    e. a frequency modulator operatively interconnected to an output portion of said amplifier, said frequency modulator further operatively interconnected to said discharge portion of said self-contained device power source;

    f. an induction coil-antenna operatively interconnected to said discharge portion of said self-contained device power source;

    g. an oscillator operatively interconnected to said modulator, said oscillator further operatively interconnected to said induction coil antenna, said oscillator further operatively interconnected to said discharge portion of said self-contained device power source; and

    h. a telemetry circuit operatively interconnected to said pressure sensor, said telemetry circuit further operatively interconnected to said discharge portion of said self-contained device power source, said telemetry circuit further operatively interconnected to said induction coil antenna; and

    a receiver for receiving data from said pressure measurement device, said receiver comprising;

    a. a self-contained or external receiver power source;

    b. at least one pickup coil operatively interconnected to a discharge portion of said receiver power source;

    c. at least one preamplifier operatively interconnected to an output portion of said pickup coil, said preamplifier further operatively interconnected to said discharge portion of said receiver power source; and

    d. a signal conditioner operatively interconnected to an output portion of said preamplifier, said signal conditioner further operatively interconnected to said discharge portion of said receiver power source.
