Instrumentation & Design Course Content

Summary

This module covers fundamental principles of the design and instrumentation processes typically required to develop medical devices. Based around a clinical scenario of enteral feeding, where liquid nutrients are pumped into a patients’ stomach or intestine via a tube, participants construct a peristaltic pump similar to those currently used. This includes mechanical, electronic and software elements to yield a computer controlled pump.

Each day consists of short seminars followed practical sessions covering the following topics.
