【Features】
1.Standardized patient simulation lateral position , perpendicular to the back and the bed , head bent to the chest , knees buckling to the abdomen , torso was Arcuate.
2.Waist can be active , the operator need to single-handedly pull simulation patient's head with one hand and pull the popliteal fossa hold of the lower limbs , spine kyphosis widened intervertebral space as possible to complete the puncture.

3.Organizational structure waist accurate landmarks obvious: a complete 1-5 lumbar spine ( vertebral body, lamina , spinous process ) , the sacrum , the sacral hiatus , sacral angle , the ligament , interspinous ligament , yellow ligament , hard ridge film and subarachnoid , and subarachnoid formed by the above-mentioned organizations , epidural , caudal ; posterior superior iliac spine , iliac crest , thoracic spinous process, lumbar spine can be real palpable .
4.Practicable following actions: spinal anesthesia , lumbar puncture , epidural , caudal nerve block, sacral nerve block , lumbar sympathetic block .
5.Lumbar puncture simulate real : When the needle arrived analog yellow ligament , the resistance increases have tough sexy ; breakthrough yellow ligament obvious sense of frustration that enters epidural , there are negative presentation ( ie, liquid anesthetic injection time as epidural anesthesia ) ; continue needle puncture the dura and subarachnoid appear a second time a sense of frustration that into subarachnoid , there will simulate cerebrospinal fluid , the whole plot of simulated clinical lumbar puncture true .
