Cross action chest compression apparatus for cardiac arrest

摘要

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.

主权项

1. An apparatus for increasing the flow of blood in a patient, the apparatus comprising:
(A) a base contoured to seat near a central region of a patient's chest; (B) an actuator; (C) a substantially inelastic belt configured to wrap around said patient's chest substantially in a plane; and (D) a force converter, mounted on said base, coupled to said actuator, and having belt connectors coupled to opposite extremities of said belt with said belt substantially in said plane, converting into belt tightening resultants applied to said belt connectors directed substantially tangentially to said chest a force manually applied to said actuator by a person placing two hands at two spatially separated points along a line making a nonzero angle to said plane and directed toward said chest, said force converter providing a substantially predefined, substantially linear path generally toward said chest for said two points to move along as said force is manually applied to said actuator at said two points.
