Abstract
Abstract A portable cervical traction device is utilized to temporarily positively maintain cervical traction while a patient is transported from a stationary traction station to another station, such as an X-ray station. While the patient is in traction at a traction station, the backplate and shoulder supports of the portable device are attached to the patient. Upstanding from the backplate are a pair of telescoping components with compression springs, and at the top of those components is a cross bar. Slide rods extend outwardly from the cross bar to overhang the shoulder supports, and a slide bar slides along the slide rods. A cam cleat on the slide bar is moved into engagement with the traction cable at the traction site, and suitable counter-traction force is applied by compressing the springs associated with the telescoping components. Then the traction cable is released from its attachment at the traction station, and is wrapped around a deck cleat. The device is utilizable with a cervical strap, tongs, halo, and like traction-facilitating devices.
