Abstract

A resuscitation device for automatic compression of 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 which repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression. An assembly includes various resuscitation devices including chest compression devices, defibrillation devices, and airway management devices, along with communications devices and senses with initiate communications with emergency medical personnel automatically upon use of the device.

Claims

1. A chest compression device comprising:

a belt which is adapted to extend at least partially around the chest of a human;

a rotating member operatively connected to the belt to constrict the belt about the chest; and

a friction liner adapted to be disposed between the belt and the chest of the human when the belt is extended around the chest of the human, said friction liner being adapted to extend substantially completely around the chest of the human, said friction liner permitting the belt to slide freely over said friction liner.

2. The chest compression device of claim 1 wherein said friction liner is composed of a low-friction material.

3. The chest compression device of claim 1 wherein said friction liner is selected from the group comprised of a belt, a vest, a corset, a girdle, a strap and a band.

4. A chest compression device comprising:

a belt which is adapted to extend at least partially around the chest of a human;

a rotating member operatively connected to the belt to constrict the belt about the chest; and

a friction liner adapted to be disposed between the belt and the chest of the human when the belt is extended around the chest of the human, said friction liner being adapted to extend substantially completely around the chest of the human, wherein said friction liner is not attached to the belt such that the belt is free to slide over said friction liner.

5. The chest compression device of claim 4 wherein said friction liner is composed of a low-friction material.

6. The chest compression device of claim 4 wherein said friction liner is selected from the group comprised of a belt, a vest, a corset, a girdle, a strap and a band.

7. A chest compression device comprising:

a belt which is adapted to extend at least partially around the chest of a human;

a rotating member operatively connected to the belt to constrict the belt about the chest; and

a friction liner adapted to be disposed between the belt and the chest of the human when the belt is extended around the chest of the patient, said friction liner being adapted to extend substantially completely around the chest of the human, said friction liner being separate from the belt.

8. The chest compression device of claim 7 wherein said friction liner is composed of a low-friction material.

9. The chest compression device of claim 7 wherein said friction liner is selected from the group comprised of a belt, a vest, a corset, a girdle, a strap and a band.

10. A chest compression device comprising:

a first belt which is adapted to extend at least partially around the chest of a human;

a rotating member operatively connected to the first belt to constrict the belt about the chest; and

a friction liner in the form of a second belt, said friction liner adapted to be disposed between the belt and the chest of the human when the belt is extended around the chest of the patient, said friction liner being adapted to extend substantially completely around the chest of the human, wherein said friction liner is not operatively connected to the rotating member.

11. The chest compression device of claim 10 wherein said friction liner is composed of a low-friction material.

12. A chest compression device comprising:

a belt which is adapted to extend at least partially around the chest of a human;

a rotating member operatively connected to the belt to constrict the belt about the chest; and

a friction liner adapted to be disposed between the belt and the chest of the human when the belt is extended around the chest of the patient, said friction liner being adapted to extend substantially completely around the chest of the human;

wherein said friction liner provides a substantially stationary surface for the compression belt to slide over as the belt is constricted about the chest by the rotating member.

13. The chest compression device of claim 12 wherein said friction liner is composed of a low-friction material.

14. The chest compression device of claim 12 wherein said friction liner is selected from the group comprised of a belt, a vest, a corset, a girdle, a strap and a band.

15. A chest compression device comprising:

a belt which is adapted to extend at least partially around the chest of a human;

a rotating member operatively connected to the belt to constrict the belt about the chest; and

a friction liner provided in addition to any clothing worn by the human, said friction liner adapted to be disposed between the belt and the chest of the human when the belt is extended around the chest of the human, said friction liner being adapted to extend substantially completely around the chest of the human, said friction liner permitting the belt to slide freely over said friction liner.

16. The chest compression device of claim 15 wherein said friction liner is composed of a low-friction material.

17. The chest compression device of claim 15 wherein said friction liner is selected from the group comprised of a belt, a vest, a corset, a girdle, a strap and a band.
