A new, low-cost homemade phantom for ultrasound-guided vascular access simulation training offers a realistic and immersive experience. This accessible prototype provides a superior alternative to expensive commercial models for medical education.
Area of Science:
- Medical Simulation
- Medical Device Design
- Ultrasound Technology
Background:
- Simulation-based training is crucial for mastering ultrasound-guided vascular access.
- Commercial ultrasound phantoms are costly, limiting accessibility.
- Existing homemade models often lack realism and reproducibility.
Purpose of the Study:
- To develop and evaluate a novel, low-cost, homemade phantom prototype.
- To create a realistic and reproducible model for ultrasound-guided vascular puncture simulation.
- To assess the prototype's cost, lifespan, echogenicity, and practical utility.
Main Methods:
- Designed a modular, reusable mold and internal vessel/gel structure.
- Evaluated prototype cost, durability, echogenicity, and user feedback.
- Expert professionals tested the phantom and completed a self-questionnaire.
Main Results:
- Prototype cost is under €100 with a shelf life exceeding 3 months.
- Manufacturing requires less than a day of effort.
- User feedback indicated predominantly positive experiences and superiority over existing phantoms.
Conclusions:
- The developed phantom is a novel, effective, and homemade solution for simulation training.
- Meets criteria for low cost, reproducibility, realism, and ecological design.
- Offers an accessible and immersive simulation experience for vascular access training.
