Abstract:
A traction device comprises a frame, a first bladder portion, a second bladder portion, a spacer, and a pump. The first bladder expands in an outward direction a distance greater than in a transverse direction. The second bladder expands in an angular direction. The second bladder is positioned generally below and to the side of the first bladder. Upon expanding in the outward direction, the first bladder bears against the back of the user's neck. Upon expanding in the transverse direction, the first bladder applies an angular traction to the cervical spine. Upon expanding in the angular direction, the second bladder bears angularly against the back of the user's upper thoracic region.
