Patent number: 8092404Abstract: 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.Type: GrantFiled: August 4, 2003Date of Patent: January 10, 2012Assignee: Deca-Medics, Inc.Inventors: Kevin A. Kelly, Thomas E. Lach, Ralph D. Lach, Arthur W. Handshy

Patent number: 4770164Abstract: A patient (10) having cardiocirculatory arrest is resuscitated using a supple band (12) that is passed around the thorax (14). The thorax is clasped at its side portions, for example, between contoured band-guide assemblies (16 and 18), one (16) being fixed and the other (18) adapted for traversing movement. The band is guided, as by the assemblies (16 and 18), over the clasped portions of the thorax so that a tautening of the band exerts the clasping action and produces force components (62, 64, 66, 68) directed inwardly of the thorax around a major portion of its periphery. The band is alternately tautened and loosened, for example, using a pull roller (72) driven manually through a torque-measuring wrench handle (110) or by a motor device (170). The tautness of the band may be limited as by an adjustable mechanical stop arrangement (128, 130, 132).Type: GrantFiled: October 16, 1980Date of Patent: September 13, 1988Inventors: Ralph D.
