发明名称 Traction apparatus
摘要 Traction apparatus for applying a traction force to a person's neck and spine including a frame assembly, a spring assembly and attachment assemblies. A first frame embodiment allows the patient to be ambulatory while traction is being pulled on the neck and spine. A second embodiment of the frame is used when the patient is in a lying position. Both frames are designed such that the traction force passes from a point of attachment of upper and lower portions of the frame assembly, which is located at the base of the user's neck through an apex of the frame assembly where the spring assembly is located. Also included are specifics to two embodiments of the spring assembly. The first embodiment being a constant force spring. The second embodiment including a torsion spring in which the traction force can be adjusted. The spring assembly is attached to the frame assembly at the apex thereof and the frame assembly is secured either directly to the body of the user as in the ambulatory embodiment thereof, or is held in position under the user's body by the user's own weight while lying thereon. The spring assembly is attachable to most common types of headgear to cause traction to be pulled on the head and neck of the user.
