Claim 7:
8. A Cardio-Pulmonary Resuscitation (CPR) system that is usable by a rescuer to care for a patient, the CPR system comprising:
a retention structure including a central member, a leg, and a back plate, the central member configured to couple to the back plate via the leg, the retention structure including a first well and a second well and an instrument locking component associated with each well;
a motor attached to the central member;
a first battery wire including a first end, a second end opposite the first end;
a second battery wire including a first end, a second end of the second battery wire opposite the first end of the second battery wire;
a first battery supported by the retention structure and configured to be electrically coupled and provide energy to the motor when the central member is coupled to the back plate;
the first battery to electrically couple to the second end of the first battery wire when the central member is coupled to the back plate,
a second battery supported by the retention structure and configured to be electrically coupled and to provide energy to the motor when the central member is coupled to the back plate, the second battery to electrically couple to the second end of the second battery wire when the central member is coupled to the back plate,
each of the first battery and the second battery including an accessory locking component, in which inserting either the first battery or the second battery into the respective well to a threshold distance permits the instrument locking component and the accessory locking component to engage with each other to prevent the inserted battery housing from sliding out of the well when a force is applied to the battery housing against the back plate;
a receiving circuit electrically coupled to the first battery, the second battery, and the motor, the receiving circuit configured to prohibit the motor from receiving energy from one of the first battery and the second battery; and
a compression mechanism attached to the central member and configured to be driven by the motor while the motor receives energy from at least one of the first battery and the second battery,
wherein the leg includes a leg electrical contact that physically contacts and is electrically coupled to the second end of the first or second battery wire,
the back plate includes a back plate electrical contact,
the battery is configured to be supported by the back plate and to electrically couple to the back plate electrical contact when supported, and
the back plate electrical contact is configured to physically touch and electrically couple with the leg electrical contact when the back plate electrical contact is electrically coupled to the central member.
