ouganically integates cervical traction and lumbar traction together；it has digital display and liquid crystal display，and can also be in-line computer with automatic compensation of traction force；in the curative course，it can select combined traction functions，such as unremitting traction，intermittent traction，mitering traction，rotaing traction；while carring out lumbar traction it can carry out cervical traction。
    The bed has unique curative method for cervical disease and protrasion of the lumbar intervertebral disci，for example，it can carry out prone-position traction and supination traction and mitering traction to make patient heightening inclined angle；while increasing vertebra gap，it generates negative pressure traction and rotating displacement to reach curative purpose；in order to ensure safe operation，it sets up tow-direction control key for patient and medical pesonnel.
