Through a partnership with a local non-profit, Christian Hospitals Overseas Securing Equipment Needs (C.H.O.S.E.N.), a cohort of engineering students starting freshmen year to present have engaged in a three-and-half year engineering design service-learning project. This cohort of students is part of the Scholars of Excellence in Engineering and Computer Science (SEECS) program funded by a National Science Foundation S-STEM Award. C.H.O.S.E.N. strengthens and advances medical technology in developing countries by providing reconstructed equipment to various mission hospitals. The overall goal of the project is to retro-actively engineer a large digital table-top medical sterilizer by eliminating the digital components vulnerable to power surges. The finished product will benefit the people in developing countries where mission hospitals may not have access to reliable power, digital equipment or dependable medical resources. Midmark, the manufacturer supplying the tabletop sterilizers being modified has discontinued older analog model, and has begun manufacturing a larger digital model as its replacement. Although the modernization provides simplicity, the mission hospitals cannot maintain the newer model due to power surges, and the older model is too small for most medical instruments, therefore needing a larger, analog model. To date, the design team has made progress converting the large digital model to analog by: (1) planning modifications for each functional system, (2) finalizing a working prototype, and (3) finalizing an assembly manual as well a modification manual. During Spring of 2018, the work plan is to present the working prototype, along with the modification and assembly manual to the stakeholder, as well as making any minor adaptations necessary. This poster presentation will summarize the design process, such as the breakdown of the systems, designs, and finalized prototype. The authors will examine how this activity, realized in a course not required for graduation, complements their engineering education experience.
