Description:
Recent advances in medical field have been fuelled by the instruments developed by the Bio-Medical and Instrumentation Engineers.
Bedside patient monitoring systems, Medical diagnostic systems are few names which have been contributed by engineers. Now
health care industry uses many instruments which are to be looked after by instrumentation engineers. This subject will enable the
students to learn the basic principles of different instruments/equipment used in the health care industry. Proficiency in this area
will widen the knowledge and skill of graduates in the field of biomedical instrumentation
Goals:



Understanding the requirements of various biomedical instruments.
Understanding of various components of Biomedical Instruments and their functioning.
Build various instruments using different blocks.
