The development of techniques and tools for the treatment of diseases is the main focus of biomedical instrumentation and research. Biomedical research engineering that deals with engineering and medicine. An application of biomedical engineering known as "bioinstrumentation" or "biomedical instrumentation" focuses on the tools and mechanics used to assess, diagnose, and treat biological systems. It focuses on a variety of sensors which are used to track a person's or an animal's physiological features. The emerging area of bioinstrumentation corners on illness treatment and unites the engineering and medical communities. The last 15 to 20 years have seen the most of the field's advances. The area of medicine has been revolutionised by bioinstrumentation, which has greatly simplified patient care. The devices/sensors transform internal body signals into electrical signals. The subfields of bioinstrumentation are numerous and include drug delivery, genetic testing, sensor development, and biomedical choices. Bioinstrumentation is related to other engineering disciplines including electrical engineering and computer science.

As examples, consider the following categories of medical equipment: life support equipment (heart-lung machines, dialysis machines, and incubators), therapeutic equipment (infusion pumps, medical lasers, and surgical machines), durable medical equipment (insulin pumps, kidney machines), and medical laboratory equipment (chemistry analyzer, blood gas analyzers, electrolyte analyzers, etc). The use of these technologies brings a new era for the medical sector. Patients with severe illnesses can now survive longer than usual. This research also includes the creation and development of artificial versions of essential organs such as liver, kidneys, and heart. This opportunity allows for the effective management of diseases and disorders.
