简介：

Overview

This study presents the development of custom ballistic gelatin ultrasound phantoms designed for ultrasound-guided regional anesthesia training. Utilizing advanced technologies like computer-aided design and 3D printing, the phantoms offer a cost-effective and durable alternative to traditional nerve block trainers.

Key Study Components

Area of Science

• Medical Education
• Simulation Training
• Ultrasound Technology

Background

• Traditional nerve block trainers are expensive and often made from perishable materials.
• Existing low-cost simulators lack durability and anatomical fidelity.
• There is a need for affordable, long-lasting training tools in medical education.
• Previous homemade trainers have significant limitations, such as rapid spoilage.

Purpose of Study

• To create durable and cost-effective ultrasound-guided nerve block trainers.
• To enhance the fidelity and accessibility of training tools for medical educators.
• To explore the longevity and maintenance of these custom trainers compared to traditional options.

Methods Used

• Utilization of computer-aided design software for phantom design.
• 3D printing models to create silicone molds.
• Poured melted ballistic gel into molds to form tissue layers.
• Evaluation of durability and cost-effectiveness of the trainers.

Main Results

• The custom trainers are made from affordable materials that last for months to years.
• They simulate anatomy more accurately than other low-cost simulators.
• These trainers require minimal maintenance compared to perishable alternatives.
• Cost significantly less than commercial nerve block trainers.

Conclusions

• The developed phantoms provide a viable solution for ultrasound-guided anesthesia training.
• They address the issues of cost and durability in medical training tools.
• This approach can enhance the training experience for medical professionals.
