Abstract
A system for performing chest compression for Cardiopulmonary Resuscitation. The system includes a motor, drive spool and associated couplings which allow for controlling and limiting the movement of the compressing mechanism and includes a control system for controlling the operation and interaction of the various components to provide for optimal automatic operation of the system.
Claims17
A device for compressing the chest of a patient comprising:
- a belt adapted to extend at least partially around the chest of the patient and fastened on the patient;
- belt tensioning means 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 tensioning means, said motor capable of operating the belt tensioning means repeatedly to cause the belt to tighten about the chest of the patient and loosen about the chest of the patient;
- a brake operably connected to the belt tensioning means and capable of holding the belt tensioning means in a tightened state about the chest of the patient;
- a controller for controlling operation of the motor and brake, said controller programmed to operate the motor and brake to cause repeated cycles of tightening of the belt to a set threshold of tightness, momentarily hold the belt at this threshold of tightness, and release the belt.

A device for compressing the chest of a patient comprising:
- a belt adapted to extend around the chest of the patient and fastened on the patient;
- a drive spool operably connected to the belt and adapted to rotate and take up the belt;
- a motor operably connected to the drive spool, said motor capable of operating the drive spool repeatedly to cause the belt to tighten about the chest of the patient and loosen about the chest of the patient;
- a brake operably connected to the drive spool and capable of preventing the drive spool from rotating;
- a controller for controlling operation of the motor and brake, said controller programmed to operate the motor and brake to rotate the drive spool to cause repeated cycles of tightening of the belt to a set threshold of tightness, momentarily hold the belt at this threshold of tightness, and release the belt.
