Model 601428 three-dimensional computer multi-functional quick, slow traction bed has been designed according to the bhysiological dissection of the lumbar inter-vertebral disc in the human body and peripheral nervous tissue characteristics with the computer program comtrol. The system software are mainly initialization program, samping program, linear and scale conversion program, expert management program etc. with the integrated electro-machinery. It takes the hydraulic pressure as the motive source and applies the advanced electronic NC tichnology for the three-dimensional directional and positioning control. It impliments thequantitative control to the three-dimensional action angles such as traction force, dlongation, yielding,rotation etc.Under the quick traction condition,the three-dimensional stereo space instantaneously fulfills to the lumbar inter-vertebral disc in a multi-angle way certain combined actions and dynamics which can not be done by the doctors by using their techniques and skills. Under the slow retraction condition, itcan carry out the continuous; intermittent;reciprocating; pulse retractions to the forward-bending waist or the staightening back in order to reach the curing purpose.

This bed has the obvious and outstanding curing to the protrusion of the lumbar inter-vertebral disc, lumbar false sliding and shifting, lumbar fast and instantaneous traction, rotation and reset. The slow speed traction utilizes the gentle traction. The traction force makes an even balancing. It is of the gentle rotation, elongation, yielding and reset. The supine lying, with the abdomen turning down can be chosen according to the patient’s conditions.
