SPRINGY BASE FOR AUTOGRAVITATIONAL SPINE TRACTION (VERSIONS) Russian patent published in 2013 - IPC A61H1/02 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment and is intended for spine traction. Springy base contains rectangular frame and support elements. Each support element is installed on corresponding to it torsion, made in form of rod with similar levers-posts on the ends and installed parallel to transverse bars of frame on two bearing supports, located on respective side piece. Each rod is provided with side rest, located perpendicular to rod axis and at equal distance from its ends. Side rests of all rods are immovably fixed on common locking element. Side rests are located relative to respective to them levers-posts at angle, ensuring required angle of inclination of levers-posts with respect to frame plane. In accordance with the second version each support element is installed on two similar torsions, made in form of rod, which has central part and curved at 90° angle to central part axis first and second ends. Central parts of each pair of torsions are located coaxially to each other, their second ends being located parallel to each other and being immovably fixed on common for all torsions locking element. Central part of each torsion is located parallel to frame transverse bars, first and second curved ends of each torsion are turned with respect to each other at angle, ensuring required angle of inclination of first end of each torsion with respect to frame plane.

EFFECT: high repeatability of value of traction effort with simultaneous simplification of construction, servicing of base and increase of its wear-resistance.
