Therapeutic device and arrangement for treating paravertebrae

摘要

A therapeutic arrangement for treating paravertebrae has a bed and a therapeutic device positioned in an opening formed in the bed. The therapeutic device has four movable cushions arranged at four corners of an H-shaped center frame. The center frame has a transverse member and two lateral pivotal arms connected to the ends of the transverse member, forming an H-shape. Each end of the pivotal arms carries one of the four cushions. The pivotal arms are connected by a coupling arm in one embodiment, each connected to an electro-mechanical moving device in another embodiment, and each connected to a pneumatic spring in yet another embodiment to control the movement of the pivotal arms so that the pads at the opposite ends of the same pivotal arm move in the opposite directions (up and down), enabling one of the pads attached to one of the pivotal arms to move in the same direction as one of the pads attached to the other of the pivotal arms. Specifically, the pivotal arms are adapted to rotate (twist) in opposite directions, thus enabling diametrically opposite ends of the pivotal arms to move in the same direction.
