This study presents the comprehensive rehabilitation of the SimMan manikin through the reconstruction of its skins and the enhancement of its electropneumatic systems. An advanced electropneumatic system was implemented, leading to a significant reduction in response time and improved valve activation accuracy. The creation of new realistic silicone skins demonstrated high durability, withstanding an average of 500 injection cycles before showing wear. Additionally, an intuitive user interface developed in Python provided precise control and monitoring of various simulation scenarios, receiving high user satisfaction ratings. The results indicate that the improved system significantly enhances the quality and effectiveness of medical simulations. The advanced electropneumatic system offers reliable and efficient control, essential for emergency scenarios. The new skins extend the manikin’s lifespan and improve the realism of simulations, allowing students to practice with materials closely mimicking human skin. The user interface facilitates the setup and monitoring of complex simulations, crucial for training in diverse clinical situations. These enhancements have significant implications for medical education, contributing to better clinical skills and decision-making training. Future research should focus on long-term validation and the integration of advanced technologies to further enhance the simulation experience. Expanding the user sample to include a more diverse group of participants will provide a more robust basis for generalizing the findings.
