Biomedical instrumentation and engineering is the application of knowledge and technology to solve problems related to living biological systems. It involves measurement of biological signals like ECG EMG or any other electrical signals generated in human being. Simultaneously diagnosis, treatment, and prevention of disease in human. As the medical field is emerging, the area of Biomedical Engineering is an expanding field. The term “Bio” is to denote something related to life. When basic of Physics and Chemistry get applied to living things, they are named as Biophysics and Biochemistry. So when the discipline of engineering and medicine interacts, it is called Biomedical engineering. Biomedical instrumentation helps physician to diagnose the problems and provide appropriate treatment to human being. Biomedical instrumentation focuses on the development of methods and devices for the treatment of diseases. It is an emerging field of biomedical engineering that bridges the gap between medicine and engineering. Examples include diagnostic equipment (medical imaging devices),durable medical equipment (insulin pumps and kidney machines), therapeutic equipment (infusion pumps, medical lasers, and surgical machines),life support equipment (heart-lung machines, dialysis machine, and incubator), and medical laboratory equipment (chemistry analyzer, blood gas analyzers, electrolyte analyzers, etc.). The application of these devices opens a new phase in the medical industry. Now you can have patients with terminal diseases living longer than usual. This research also extends to the field of artificial organs where vital organs, including the liver, kidneys, and heart, are designed and developed. This present opportunity allows for the effective management of diseases and disorders.
The basic components of this system are the same as in any other instrument system .The only difference is in this case the living human being is considered a subject. The main components are :
