1. A power supply interface system for a medical device, the power supply interface system comprising:

  • a battery compartment defining at least a first battery area and a second battery area, the first battery area configured to receive a first battery and the second battery area configured to receive a second battery; and

    a battery interlocking system associated with the battery compartment, the battery interlocking system including;

    a first interlock mechanism including;

    a first locking portion configured to move between a first locking position and a first non-locking position, wherein in the locking position the first locking portion directly physically engages with the first battery to physically restrain the first battery and thereby substantially prevent removal of the first battery from the first battery area, and wherein in the non-locking position the first locking portion does not physically engage with the first battery and thus does not prevent removal of the first battery from the first battery area; and

    a first selector configured such that during insertion of the second battery into the second battery area, the second battery physically causes the first selector to move the first locking portion from the locking position substantially preventing removal of the first battery from the first battery area to the non-locking position not preventing removal of the first battery from the first battery area;

    a second interlock mechanism including;

    a second locking portion configured to move between a second locking position and a second non-locking position, wherein in the locking position the second locking portion directly physically engages with the second battery to physically restrain the second battery and thereby substantially prevent removal of the second battery from the second battery area, and wherein in the non-locking position the second locking portion does not physically engage with the second battery and thus does not prevent removal of the second battery from the second battery area; and

    a second selector configured such that during insertion of the first battery into the first battery area, the first battery physically causes the second selector to move the second locking portion from the locking position substantially preventing removal of the second battery from the second battery area to the non-locking position not preventing removal of the second battery from the second battery area.
