ABSTRACT:
A back traction device is disclosed that allows a person to be seated in any type of seat and will relieve the pressure, weight and tension on the disc of the lower back of the patient as much as possible. The back traction device consists of a halter that serves to transfer some of the pressure that is associated with sitting in a seat or chair off of the patient's lower back. The back traction device further includes a two-part traction member having a clip-like portion to be received over the back of the seat and a downwardly extending strap portion to be connected to the clip portion. The clip portion is first affixed to the seat back and the strap portion connected thereto. The strap portion has a securing surface that will attach to a corresponding securing surface on the halter member. An inflated air cushion is disposed between the seat occupant and the seat prior to connection of the halter to the strap portion. Since the air cushion is inflated it lifts the seat occupant off the seat at which time the halter is connected to the strap portion. Once the halter has been connected to the strap portion, the air cushion is slowly deflated and the pressure and weight of the seat occupants upper body is transferred through the halter, to the strap portion, and therethrough to the seat. Optionally, a padded back portion may also be attached to provide further support and proper curvature to the patient's lower back.
