Abstract: Manual CPR apparatus allowing the application of force at two points separated by a line making a nonperpendicular angle relative to the longitudinal axis of the patient. The line separating the two force points may also lie out of the plane formed by the device's belt which circumnavigates the patient's torso. These geometrical configurations allow the facile application of the CPR force to the device by one or more operators located along the side of the patient. The device may have the capability to limit the achieved circular chest compression to one of a plurality of magnitudes. The device may also provide signals to indicate the appropriate times for applying pressure and may incorporate electrocardiogram and defibrillation components. The device may contact the patient's chest with a suction cup or other adhering component to assist in the patient's chest expanding in the interval between compressive strokes.

Abstract: A manual CPR apparatus for increasing the flow of blood in a patient suffering cardiac arrest. A force multiplier mounts to a base contoured to seat near a central region of the patient's chest. The force multiplier connects to a manual actuator and belt connectors which, in turn, connect to opposite ends of a substantially inelastic belt wrapped around the patient's chest. The force multiplier doubles the force manually applied to the actuator and directs it through the base toward the chest. The force multiplier includes two assemblies. The first has a pair of arms rigidly connected in the same plane to a trolley assembly and two grippable handles extending perpendicularly from either side of the trolley assembly. The second assembly has a pair of vertical struts that attach to opposite sides of the base on either side of the pair of arms of the first assembly.

Abstract: The invention is an apparatus for increasing intrathoracic pressure for resuscitating cardiac arrest patients. The apparatus comprises a flexible, substantially inelastic belt wrapped around the patient's chest and attached to a force converter. The force converter converts a downwardly directed force into a chestward resultant, which depresses the sternum, and two belt tightening resultants. The force converter comprises a pair of arm assemblies, each having a pair of spaced arms, which are pivotably mounted to a base. The base is positioned near the patient's sternum and the ends of the belt attach to one end of each arm assembly. The opposite, handle ends of the arm assemblies are depressed toward the chest causing tightening of the belt and compression of the chest cavity.
