Abstract
A device for being positioned beneath the back of a human lying supine on a support surface to aline that human's spine. Two upwardly extending elongated ridge members are joined together in a substantially parallel and alined position. Each ridge member has a first end and a second end and an upper surface. The upper surface of each ridge member forms a convex curve substantially at the first end thereof that substantially corresponds to the natural lumbar curve of a human spine, forms a concave curve intermediate the first and second ends thereof that substantially corresponds to the natural thoracic curve of a human spine, and forms a convex curve substantially at the second end thereof that is slightly less than the normal cervical curve of a human spine.
Claims11
A device for use in alining a human spine, said device comprising:
- first and second elongated ridge members and a bridge means for holding said first and second elongated ridge members substantially parallel to and alined with one another at a substantially constant distance apart from one another, each of said ridge members having a first end and a second end and an upper surface, said upper surface of each of said ridge members being continuous and gently curved and forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof and forming a substantially flat, sloping area adjacent said first end thereof.
A device for being positioned beneath the back of a human lying suprine on a supporting surface to aline that human's spine, said device comprising:
- (a) a base member for resting on said support surface;
- (b) a first upwardly extending elongated ridge member positioned on said base member, said first ridge member having a first end and a second end and having an upper surface, said upper surface of said first ridge member forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof, and forming a substantially flat, sloping area adjacent said first end thereof;
- and
- (c) a second upwardly extending elongated ridge member positioned on said base member substantially parallel to and alined with said first ridge member and spaced apart from said first ridge member at a substantially constant distance, said second ridge member having a first end and a second end and having an upper surface, said upper surface of said second ridge member being continuous and gently curved and forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof, and forming a substantially flat, sloping area adjacent said first end thereof.
