Abstract
An automated chest compression device has a housing for supporting a patient and a motor within the housing. A conical drive spool is operatively connected to the motor and a cable, is operatively connected to the conical drive spool. The cable is adapted to extend at least partially around the chest of the patient. A controller is operable to control the motor to compress the chest to variable thresholds.
Claims9
An automated chest compression device comprising:
- a housing for supporting a patient;
- a motor within the housing;
- a conical drive spool operatively connected to the motor;
- a cable, operatively connected to the conical drive spool and adapted to extend at least partially around the chest of the patient;
- and
- a controller operable to control the motor to compress the chest to variable thresholds.

A method of performing chest compressions on a patient comprising the steps:
- providing an automated chest compression device comprising:
- a housing for supporting a patient;
- a motor within the housing;
- a conical drive spool operatively connected to the motor, the conical drive spool having a base and a peak wherein the base of the conical drive spool has a larger diameter than the peak;
- a cable, operatively connected to the base of the conical drive spool and adapted to extend at least partially around the chest of the patient;
- and
- a controller operable to control the motor to compress the chest to variable thresholds;
- placing the patient on the housing;
- securing the cable about the chest of the patient;
- and
- repetitively tightening the cable around the base of the conical drive spool, thereby creating a large mechanical advantage when starting a compression and the cable then spools around the conical drive spool, proceeding towards the peak to compress the chest of the patient.
