DIY Ultrasound Model: Procedure – Lumbar Puncture
This page summarizes do-it-yourself (DIY) ultrasound models for teaching the lumbar puncture. Read more on the DIY ultrasound model compendium.
A Low-Cost Ultrasound Phantom of the Lumbosacral Spine1
|Materials||Lumbar spine model, gelatin, 4 L container for the model, epoxy adhesive|
|Estimated Cost||Approximately $40|
A lumbar spine model is secured to the bottom of a 4 liter container with epoxy. The container is then filled with gelatin, which is allowed to harden. The model may be microwaved to remove old needle tracks. I believe this model could be improved by generating synthetic skin to allow learners to mark the “skin” as they would during the actual procedure.
Versatile, Reusable, and Inexpensive Ultrasound Phantom Procedural Trainers2
|Materials||Ballistics gel, latex tubing, spinal model, container for the model|
|Estimated Cost||Approximately $60|
Latex tubing is filled with clear liquid and then vertically threaded through a spinal model. The entire apparatus is then taped to the bottom of a container, which is then filled with ballistics gel.
