1. A device for compressing a chest of a patient comprising:
- a platform for placement under a thorax of the patient;
a compression belt adapted to extend over an anterior chest wall of the patient, said belt comprising a load distribution section and right belt end and a left belt end;
a motor operably connected to the belt through a drive train, said motor capable of operating the drive train repeatedly to cause the belt to tighten about the thorax of the patient and loosen about the thorax of the patient;
whereinthe drive train comprises a right drive spool and a left drive spool, said right drive spool and left drive spool disposed laterally in the housing, and a linkage operably connecting the motor to said right drive spool and left drive spool; and
the right belt end and the left belt end are releasably attachable to the right drive spool and left drive spool, respectively, at attachment points accessible from anterior or lateral sides of the platform, such that the right belt end and left belt end may be attached to the right drive spool and the left drive spool while the platform is disposed under the patient.

14. A method of performing chest compression on a patient, said method comprising the steps of:
-
providing a device for compressing a chest of a patient, said device comprising; a platform for placement under a thorax of the patient; a compression belt adapted to extend over an anterior chest wall of the patient, said belt comprising a load distribution section and right and left belt ends; a drive train operably connected to the belt for repeatedly tightening and loosening the belt around the chest of the patient; a motor operably connected to the belt through a drive train, said motor capable of operating the drive train repeatedly to cause the belt to tighten about the thorax of the patient and loosen about the thorax of the patient;
whereinthe drive train comprises a right drive spool and a left drive spool, said right drive spool and left drive spool disposed laterally in the housing, and a linkage operably connecting the motor to said right drive spool and left drive spool; and the right belt end and the left belt end are releasably attachable to the right drive spool and left drive spool, respectively, at attachment points accessible from anterior or lateral sides of the platform, such that the right belt end and left belt end may be attached to the right drive spool and the left drive spool while the platform is disposed under the patient; placing the patient on the platform, with the anterior side of the platform in contact with the thorax of the patient; thereafter, while the patient is disposed on the platform, attaching the right belt end to the right drive spool, and attaching the left belt end to the left drive spool; and initiating operation of the device to cause repeated cycles of tightening and loosening of the belt about the thorax of the patient. - View Dependent Claims (15, 16, 17, 18)

19. A device for compressing a chest of a patient comprising:
-
a platform for placement under a thorax of the patient, characterized by an anterior/posterior axis corresponding to the anterior/posterior axis of a patient on which the device is used, and characterized by an inferior/superior axis corresponding to the inferior/superior axis of a patient on which the device is used; a compression belt adapted to extend over an anterior chest wall of the patient, said belt comprising a load distribution section, and right and left belt ends; right and left drive spools laterally displaced from an inferior/superior centerline of the platform, said right and left drive spools operably connected to the right and left belt ends such that rotation of the right and left drive spools results in pulling the right and left belt ends posteriorly, for repeatedly tightening and loosening the belt around the chest of the patient; a motor operably connected to the right and left drive spools, through a drive train, said motor operable to rotate the right and left drive spools. - View Dependent Claims (20, 21)
