【Features】
1. Simulation model for standard lumbar puncture position, the skin is soft, feel real;
2. With complete spinal cord, clear and obvious iliac spine clearance on spine after sign, easy to puncture positioning.
3. Piercing has a real sense of block and frustrated feeling, and cerebrospinal fluid flow simulation.

4. Life size infant, side lying on the lamina dura bed, head bend to the chest, both hands hold knees, bend knees to the abdomen and low back bend as far as possible, also can be in sitting position.
5. Accurate bone marker: obvious interspace of spinous process and posterior superior iliac spine;

6. Puncture position: 3-4 lumbar intervertebral space;
7. Realistic touch feeling and a characteristic of "pop" can be felt when  needle penetrates into veins, outflow of simulated cerebrospinal fluid proves correct puncture position;
8. With spare canalis spinalis and puncture needle.
