CPR chest compression system with motor powered by battery located away from the motor

A Cardio-Pulmonary Resuscitation (CPR) system that is usable by a rescuer to care for a patient, the CPR system comprising:

• a retention structure that includes a central member, a leg and a back plate, the central member configured to become coupled to the back plate via the leg, the retention structure configured to retain a body of the patient when the central member is thus coupled;
• a motor attached to the central member;
• a battery wire having a first end electrically coupled to the motor, and a second end opposite the first end, the battery wire having a length of at least 6 cm between the first end and the second end, a supported portion of the battery wire that is least 4 cm long being supported by the leg;
• a battery block configured to store energy and to be supported by the retention structure, the battery block configured to become electrically coupled to the second end of the battery wire when the central member is thus coupled, the motor being configured to receive energy from the battery block via the battery wire when the central member is thus coupled, the battery block has having a battery housing that is configured to be supported by the leg, and a cell within the battery housing that is configured to store the energy;
• and
• a compression mechanism attached to the central member and configured to be driven by the motor while the motor thus receives energy, the compression mechanism configured to perform, while thus driven and the body is retained by the retention structure, automatically CPR compressions alternating with releases to a chest of the body, the CPR compressions thus causing the chest to become compressed by at least 2.5 cm.

• a battery first block configured to store energy and to be supported by the retention structure, the battery block configured to become electrically coupled to the second end of the battery wire when the central member is thus coupled, the motor being configured to receive energy from the battery block via the battery wire when the central member is thus coupled;
• a second battery block that is supported by the back plate, and configured to store energy, the second battery block configured to be supported by the retention structure and to be electrically coupled to the motor when the central member is thus coupled, the motor being configured to receive energy from the first battery block when the central member is thus coupled;
• a receiving circuit having a central node, the central node electrically coupled to the first battery block, the second battery block and the motor the receiving circuit configured to prohibit the motor from receiving energy from one of the first battery block and the second battery block;
• and
• a compression mechanism attached to the central member and configured to be driven by the motor while the motor thus receives energy, the compression mechanism configured to perform, while thus driven and the body is retained by the retention structure, automatically CPR compressions alternating with releases to a chest of the body, the CPR compressions thus causing the chest to become compressed by at least 2.5 cm.
