Lesson notes

Learning Objectives

Indicator: 3.3.1.LI.1 - Evaluate the role of biomedical engineers in the production, acquisition and maintenance of medical devices.

By the end of the lesson, learners can:

Explain the three core phases of a biomedical engineer’s work: production, acquisition, and maintenance of medical devices.
Describe at least two specific activities a biomedical engineer performs in each of the three phases, using examples of diagnostic devices common in Ghanaian hospitals.
Evaluate the importance of testing, calibration, and software upgrades in the maintenance of diagnostic devices.
Assess how biomedical engineers balance safety, efficacy, and cost-effectiveness when advising hospitals on acquiring new medical technology.
Present a reasoned evaluation of the biomedical engineer’s role, citing evidence from group research or site visits.

Exemplars (from the NaCCA curriculum)

Exploratory Learning: In groups, visit various medical or production centres to learn about the activities in the production (e.g., medical need, design, prototyping, etc.), acquisition (e.g., advice on new medical technology, safety, efficacy, and cost-effectiveness) and maintenance (e.g., testing, software upgrade, repairs, calibration, etc.) of medical devices. Subsequently, the individual groups make presentations to the class for further discussion.
