Abstract

This study aimed to develop and biomechanically validate a modular skin traction prototype specifically tailored for resource-limited settings, addressing critical limitations in force precision and pressure injury mitigation inherent to improvised solutions. A developmental research design employed empirical mechanical testing to calculate the force transmission ratio and confirm the mechanical efficiency. Biomechanical safety was established by simulating and measuring the peak interface pressure and maximum shear stress. The prototype’s clinical viability was then assessed through remote validation via an ordinal survey from three independent orthopedic specialists, with inter-rater agreement quantified using Kendall’s Coefficient of Concordance. The prototype achieved a high mechanical efficiency of 95.05%, demonstrating reliable force delivery. Biomechanically, Pmax was 5.8 kPa, confirming safety below the 6.0 kPa capillary closing threshold. Specialist validation yielded perfect consensus (W=1.00) across all nine criteria, resulting in a unanimous recommendation to proceed to clinical trials, contingent on design refinements suggested in the qualitative consultation. The key limitations are the absence of a formal, integrated design thinking process and the lack of full adherence to regulatory standards (e.g., ISO 13485). The findings provide a validated engineering foundation, proving that low-cost materials can meet stringent biomechanical safety requirements, which is crucial for developing a scalable medical device.
