This pediatric lumbar puncture trainer simulates a two-week old baby that can be positioned either in the lateral decubitus position or held upright in the sitting position. The body form is anatomically correct with an iliac crest and umbilicus. The replaceable tissue has L3 – L5 vertebrae with a sacrum and the gluteal fold. Each tissue includes a spinal cord filled with simulated CSF and the epidural venous plexus filled with simulated blood.
