Open Source Design for BioMedical Engineering (OS4BME)

The Problem: Healthcare in Africa

The scarcity of accessible quality healthcare in Africa is inextricably linked not only with the lack of resources, but also the lack of trained biomedical engineers. As a result, the medical device industry in Africa is largely absent and there is an over reliance on foreign companies to repair and design biomedical instrumentation and resolve technical problems. Tied with this, the mainstream academic engineering community in Africa remains largely ignorant of the potential or pitfalls of open source software, hardware and prototyping. More importantly, at present there are no specific engines or platforms focused on the sharing of biomedical instrumentation and devices. This is because, by their very nature, biomedical devices possess stringent performance requirements to comply with regulatory standards to ensure patient safety. Action A one week introductory course on open source design and rapid prototyping specifically for Biomedical Engineering will be held during the Innovator’s Summer School. The aim of the course is to introduce the open source concept to the African Engineering community and thus develop and nurture resource sharing and technological self-competency. Close attention will also be paid to safety and ergonomic aspects such that the devices meet with regulatory and performance standards for biomedical devices.

Implementation

The course will be held by the University of Pisa’s Center for Bioengineering and Robotics and Fablab Pisa. It will involve setting up a 3D printing system, design of a neonatal monitoring device from first principles using open source electronics based on the Arduino platform. Participants will play an active role in the identification of components, design, assembling and testing of the device and in the discussion of regulatory issues in the development of the device.

Course outcome

Participants will gain hands on experience in open source DIY based on rapid prototyping, with particular focus on biomedical systems, their requisites, limitations and safety requirements. The design philosophy and information gained will be used to create a novel properly regulated sharing platform for biomedical design and project development and exploitation throughout Africa.
