pillow for patients with cervical disc herniation

The invention also secure the shape memory alloy wire relates to a pillow apparatus for inducing cervical extension exercise for cervical disc herniations patient through the height change of the headrest according to the length adjustment of the shape memory alloy wire and induce a long-term rehabilitation At the same time length a power unit for providing power to the level below the size control over the change, control level below the size of converting caused tension by the length variation of the wire into a linear motion, horizontally by this engagement of the horizontal below the size air below the size control of the movement by the first gear for converting a rotational movement, the shaft for transmitting the rotational motion of the first gear to the second gear and third gear, a second gear, a rotary part including a third gear, this engagement of the second gear 2 air below the first vertical size for converting the rotational movement of the gear into a linear motion, by this engagement of the third gear for converting a rotary motion into a linear motion of the third gear The second vertical size control below, comprises a first vertical size eel below the driver, consisting of a headboard fixed to the second vertical size control below. A pillow device according to the present invention is a method for controlling the flow of electric current allowing the user to derive the desired cervical extension exercise continuous physical stimulus to assist in rehabilitation, and can periodically, and driven by a conventional motor no noise and vibration in enables users to be more comfortable providing physical therapy.
