A traction device for use on a support surface which includes a body contacting assembly which releasably contacts the a suitable anatomical region of the patient, a gas spring and associated assembly, the gas spring variable between an extended rest position and a retracted force exerting position, and means of relieving traction force exerted by the gas spring and associated assembly.

A vehicle wheel end assembly includes a sleeve member that allows air to be vented from the wheel end while significantly reducing venting of lubricating fluid. The wheel end includes a hub that is driven by a gear assembly. Lubricating fluid is stored within the hub to lubricate the gear assembly. Air pressure that builds up within the wheel end during vehicle operation is vented from the wheel end assembly via a vent path. A sleeve is installed within the wheel end to block the lubricating fluid from entering the vent path.

A cervical traction device which can be used on a elevated support surface such as a bed which applies a tractive force to the back of the patient's skull approximate to the occipital bone through the use of contoured blocks which can preferably be positioned behind the patient's head and mounted on a head rest assembly. The tractive force can be continuous or cycled on and off manually during a cervical traction session. The head rest assembly slides on the bed or similar surface and can be vertically and laterally adjusted to vary the flexion-extension angle. The cervical traction device can be operated by the patient with or without the help of a second party.

A cervical traction device which can be used on a support surface such as a bed which applies a tractive force to the back of the patient's skull approximate to the occipital bone through the use of contoured blocks which can preferably be positioned behind the patient's head and mounted on a head rest assembly. The tractive force can be administered in a continuous cyclical or intermittent manner controlled by the patient during a cervical traction session. The device has an integrated damping system which permits return of tractive force to the patient during each cycle in a gradual fashion. This gradual return enables this unit to closely simulate cyclic, and cyclic intermittent traction performed in the more expensive in-office equipment used by physical therapists. The head rest assembly slides on the bed or similar surface and can be vertically and laterally adjusted to vary the flexion-extension angle. The cervical traction device can be operated by the patient with or without the help of a second party. The mechanism is configured with gas springs to control the rate of descent of the weight and apply a constant tractive force to the patient in a manner which maximizes safety.
