Claim:
An electro-mechanical chest compression device comprising: a housing for supporting a patient's back; a motor disposed in the housing below the patient when the patient is supported by the housing; a channel beam mounted to the housing, said channel beam laterally oriented with respect to the patient and defining a channel that extends laterally across the width of the housing; a drive spool spanning the channel beam, said drive spool operably attached to the motor and rotatably attached to the channel beam, wherein the motor is capable of rotating the drive spool; a belt attached to the drive spool and disposed laterally within the channel, said belt capable of extending at least partially around the chest of a patient, wherein rotation of the drive spool tightens the belt to compress the chest of the patient; a spline attached to the belt; and a slot disposed in the drive spool along the length of the drive spool, said slot sized and dimensioned to closely match the size and dimensions of the spline, wherein the belt is attached to the drive spool when the spline is disposed in the slot.
