Module Title:Medical Devices and Instrumentation
Language of Instruction:English
Credits: 5
NFQ Level:6
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: (a) Teaching will be conducted using lectures, tutorials and practical laboratory sessions. (b) The Institute’s VLE will be used to evaluate the students understanding of the basic concepts during each section using online quizzes. (c) At the end of each section, self-test tutorial question sheets will be issued to the students. They will have one week to complete these questions. Any difficulties arising from the self-test question sheets will be addressed in class or laboratory sessions. (d) At various stages of the module students will be directed to online materials and resources and will also have to conduct independent research on specific topics for purpose of completing practical exercises and assignments. (e) The practical laboratory sessions will offer the students hands on laboratory experience using real measurement and test equipment, experimental apparatus, and computational software environments. These applied experiments will serve to reinforce the theoretical knowledge and understanding of real-world systems.
Module Aim: The aim of this module is to provide the student with knowledge and understanding in relation to medical instrumentation in terms of the principle, applications and design considerations for medical instrumentation circuits and systems. The module focuses on the main concepts of medical instrumentation, sensors and principles, biopotentials, electrodes and amplifier design considerations, blood pressure, measurement of flow and volume, respiratory system, measurement and modelling, clinical laboratory instrumentation approaches, and finally, the operation of various therapeutic and prosthetic devices.
