Level: 7
Department: Biomedical Equipment Technology
Institution: Rwanda Polytechnic / Kigali College of Technology
Module Duration: One Semester
Instructor: Gedeon NDAYISHIMIYE, LLB, BME

I.                Module Description

This module is designed to provide students with theoretical knowledge and hands-on skills in the installation, operation, routine maintenance, and fault diagnosis of key biomedical diagnostic equipment. It covers a wide range of devices commonly used in clinical laboratories, ophthalmology, and ENT (Ear, Nose, and Throat) practice settings.

Students will explore equipment functionality, installation standards, safety compliance, electrical considerations, and preventive maintenance strategies essential for ensuring reliable performance and patient safety.

II.             Learning Outcomes

Upon successful completion of this module, students will be able to:

1. Identify, describe, and install diagnostic laboratory equipment and ophthalmic/ENT devices.
2. Apply operational principles to the use and troubleshooting of microscopes, analyzers, and water systems.
3. Perform preventive and corrective maintenance on biomedical and optical equipment.
4. Document maintenance history, calibrations, and repairs in line with biomedical engineering protocols.
5. Implement best practices for electrical safety, optics care, and part replacement.

This module describes the skills, knowledge and attitude required to apply medical health and safety procedures in installing and maintaining biomedical equipment. At the end of this module, students will be able to describe management of health and safety in health facilities, describe workplace health and safety regulations, and ensure appropriate risk control measures to hazards and risks in health facilities.

Technical drawing, also known as drafting, is a detailed graphic rendition of how something functions or how it is built. Technical drawings are made at a precise scale and include elements that make them unambiguous, meaning that their elements can be interpreted only in one way

This module describes knowledge, skills, and attitude required to install and maintain diagnostic equipment. By the end of this module, students will be able to perform installation and maintenance of clinical laboratory equipment, perform installation and maintenance of ophthalmology equipment, and perform installation and maintenance of ENT Equipment.

This Module describes the knowledge, skills and attitude required to apply basic discrete mathematics. At the end of this Module ,the trainee of Level Six will be able to apply Elementary logic, Techniques of counting, Discrete probability, Elementary number theory, Cryptography, Elementary graph theory and finite state of Automata.

This course aimes at raising the awarness of   the importance of learning English for students' future career.Through in-class discussions and journals , students will be able to use effectively  the appropriate English  as regard  to their specific area while  using  technical language in different situations where it is required , describing tools used in Biomedical technology   and accurately read texts and documents containing technology terms  related to medical,electrical and electronic equipment.  besides  the  use of  appropriate grammar in different written and spoken situations will a be focused on..
