Publication number: 20230172800Abstract: A manual restorative therapy tool is presented. A first tool includes a body, a first contact surface coupled to the first surface of the body, and second contact surfaces coupled to the second surface of the body, wherein each second contact surface of the array is smaller than the first contact surface. A handle may be coupled to a third surface that allows either the first or the second contact surface to be pressed against a user, expanding the user's blood vessels and lymphatic vessels. In this state, circulation may be further enhanced by use of a second tool having a handle with a first end and a second end, a first contact surface coupled to the first end via a compression mechanism, and a second contact surface coupled to the second end via a flexibility mechanism. The first and second contact surfaces independently spin with respect to the handle.Type: ApplicationFiled: December 8, 2021Publication date: June 8, 2023Inventor: David Hyun Jong Cho

Publication number: 20230054542Abstract: A spine treating apparatus is presented. The apparatus includes a plurality of frames arranged in an x-direction to form a surface, suspension pieces supporting the plurality of frames, a rotator on which the suspension pieces rest, and a motor that turns the rotator about an axis that extends in the x-direction. The rotator has an uneven outer surface such that when the motor turns the rotator, the suspension pieces move according to the contours of the rotator's uneven outer surface. The movement of the suspension pieces treats the back of a patient lying on the surface. A method of treating a user's spine is also presented. The method entails arranging frames to form a surface, providing a suspension piece for each of the frames to support the frames, providing a rotator with an uneven surface to contact the suspension piece, and turning the rotator.Type: ApplicationFiled: August 19, 2021Publication date: February 23, 2023Inventor: David Hyun Jong Cho
