Abstract
A resuscitation device for automatic compression of a victim's chest using a compression belt which exerts force evenly over the entire thoracic cavity. The belt is constricted and relaxed through a motorized spool assembly that repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression.
Claims30
A device for compressing the chest of a patient, said device comprising:
- a belt which is adapted to extend at least partially around the chest of the patient;
- a rotating member operatively connected to the belt such that rotation of the rotating member spools the belt upon the rotating member to constrict the belt about the chest of the patient;
- a motor for rotating the rotating member;
- said rotating member being of a diameter chosen so as to require rotation exceeding one full rotation of the rotating member to effect belt take-up and resuscitative compression of the chest.

A method of performing chest compressions on a patient, said method comprising the steps of:
- providing a device for compressing the chest of a patient, said device comprising:
- a belt which is adapted to extend at least partially around the chest of the patient;
- a rotating member operatively connected to the belt such that rotation of the rotating member spools the belt upon the rotating member to constrict the belt about the chest of the patient;
- a motor for rotating the rotating member;
- said rotating member being of a diameter chosen so as to require rotation exceeding one full rotation of the rotating member to effect belt take-up and resuscitative compression of the chest;
- and
- performing chest compressions.

A method of treating patients, said method comprising the steps of:
- providing a blood flow increasing apparatus, said apparatus comprising:
- a belt which is adapted to extend at least partially around the chest of the patient;
- a rotating member operatively connected to the belt such that rotation of the rotating member spools the belt upon the rotating member to constrict the belt about the chest of the patient;
- a motor for rotating the rotating member;
- said rotating member being of a diameter chosen so as to require rotation exceeding one full rotation of the rotating member to effect belt take-up and resuscitative compression of the chest;
- a clutch operably connected to the motor and to the rotating member;
- seating the blood flow increasing apparatus on the chest of a patient;
- wrapping the belt around the chest of the patient;
- fastening first and second opposite extremities of the belt to the apparatus;
- operating the apparatus to apply a chest compressing force to the patient;
- and
- operating the clutch while the device is operating to connect the motor to the rotating member.
