Internationales SkillsLab Symposium 2025 Workshop 4: A novel simulation-based trainer for peripheral venipuncture München 20250319 20250321 25isls39 TextBackground and motivation: Simulation-based training provides a stress-free, controlled environment in which medical trainees can refine venipuncture skills without the immediate pressures or risks encountered in clinical settings. Venipuncture is essential in diagnostics, therapy, and blood product extraction, yet it often provokes uncertainty in both patients and practitioners. Challenges such as obese or edematous extremities underscore the need for repeated, stress-free practice. Electronic feedback in simulations fosters confidence and precision by delivering instantaneous error correction.Description: We present a significantly updated electronic venipuncture trainer that surpasses our initial foil-based prototype. The current model features carbon-fiber-infused conductive silicone embedded in a durable silicone pad containing two large, pressurized veins. Trainees use butterfly needles or peripheral IV cannulas to puncture the front wall of the vessel and aspirate water from an integrated reservoir. If they inadvertently pierce the back wall – or otherwise misplace the needle – an arduino-driven system detects the short circuit and provides real-time visual and audible signals, enabling immediate recognition of errors. By replacing aluminum foil with conductive silicone, the trainer preserves more realistic haptics and offers enhanced durability without corrosion issues.Reflection and outlook: This iteration provides improved tactile feedback and accommodates skill levels ranging from basic blood draws to more advanced IV medication administration scenarios. Building on this success, we aim to extend silicone-based simulation dummies with immediate electronic feedback to other invasive procedures, such as lumbar punctures, suprapubic catheter placement, and even conventional or minimally invasive surgeries. By refining the electronic sensing and pressurized vein models, and expanding to multiple procedure types, our trainer ultimately seeks to reduce patient risk by offering a robust, interactive environment in which trainees can master critical skills under safe, simulated conditions.
