Carries out three dimension stero traction curing for the lumbar intervertebral disci ，The bed’s traction force，traction time ，mitreing angle ，rotating angle，unremitting traction intermittent traction all are controlled by micro computer ；the　parameters showing ways include digtal dispiay and liquid crystal，under the　state  of traction curing the traction force can be compensated automatically.
  The clinical application can implement the longitudinal traction mitreing traction rotction rotating traction etc. multi function traction curing to overcome single traction action and helghten curative effeat.

TECHNICAL PARAMETERS:
   Power source：220V/50Hz
   Power:360W
   Traction force：0-99Kg
   Total traction time:0-60min
   Traction time:0-9min
   Intermittent time:0-90s
   Lumbar traction travel:0-200mm
   Mitering angle：upper 20°-lower 10°
   Rotating angle：left 25°-right 25°

TECHNICAL FEATURES:
   1,Code tube displays traction force ,traction time(all Chinese liquld crystal screen displaying traction force,traction time)
   2,Micro computer controls the motor‘s power ；the　traction force can be compensated automatically
   3，Eight kinds of traction modes can be of unremitting traction and intermittent traction as well.i，e，it can be of single traction and of three-     dimension combined traction as well。
   4，Eiectronic sensor conteols traction force；photoelectric switch controls rotating angle it has quickly drawing back switch and quickly drawing back key。
