Abstract:
     An educational and experimental model of lumber numbness is composed of a base, a supporting rod, an experimental plate of lumber numbness and is bracket, and an angle scale.The experimental plate's bracket its joined to the top end of supporting rod via axle-pin. The angle scale is connected to one end of said supporter via axle-pin. The experimental plate is linked to its bracket via hinges. On the experimental plate, there is a slot similar to the length and curvature of human sagittal vertebra. A transparent gelatin tube containing prepared cerebrospinal fluid is embedded in the slot. The spinal bones and spirous processes are printed at two sides of slot. The moving and diffusion of local anesthetic in cerebrospinal liquid can be simulated and observed.
