Abstract
There is significant variability in the realism, cost, and structural integrity of sonographic simulators available for use currently. A common material that is used for the production of sonographic simulators is synthetic ballistic gelatin, which requires a high melting temperature for molding. In this experiment, we investigated the structural integrity of high-density polyethylene (HDPE) when exposed to melted ballistics gel for the assimilation of a sonographic lumbar puncture simulator.

Medical simulation is a vital tool for procedural skills training and assessment [1]
High-density polypropylene (HDPE), known as “marine starboard,” is a robust thermoplastic that is often used in the construction of waterproof vessels
We compared the structural integrity of polypropylene to HDPE when exposed to melted ballistics gel for the assimilation of a sonographic lumbar puncture simulator
Summary
Medical simulation is a vital tool for procedural skills training and assessment [1]. Relatively low cost, and ease of construction make it a suitable material for the creation of simulators that require the molding of melted ballistics gel. In this experiment, we compared the structural integrity of polypropylene to HDPE when exposed to melted ballistics gel for the assimilation of a sonographic lumbar puncture simulator. A housing box for the lumbar puncture simulation was constructed successfully with dimensions of 13 inches x 5 inches x 5 inches to allow for the placement of a spine model within the container. Sonographic images obtained using the lumbar puncture simulator were of high quality and adequately demonstrated needle placement for trainee instruction (see Figure 4)
