Vital Sign Monitor Verification Device for Guatemalan Technicians

We're an international and interdisciplinary senior design team in the Collaborative Community Capstone in the Kate Gleason College of Engineering. We're working with Guatemalan engineering students and biomedical equipment technicians to make equipment diagnostics more reliable. Specifically, we are simulating patient signals like blood oxygen concentration and blood pressure in order to verify the performance of patient monitors in low-resource contexts. Our stakeholders are interested in a budget-friendly, replicable patient simulator that can be constructed and maintained by local technicians. On selected parameters, our final product will be competitive to devices currently on the market for thousands of dollars – and we’re on track to deliver a solution under $500. Our proposed solution will be entirely manufacturable in its local context, using standard parts and processes. By focusing on pulse oximetry and non-invasive blood pressure simulation, we’ll deliver reliable, low-cost solutions for less saturated markets.
