Definition and scope of biomedical instrumentation
Biomedical instrumentation is defined as the application of engineering principles and techniques to measure, record, process, analyze, display, transmit, or control physiological variables or biological phenomena. The scope of biomedical instrumentation encompasses various disciplines such as electronics, electrical engineering, computer science, mechanical engineering, biomedical engineering, bioengineering, biophysics, biochemistry, biology, medicine, etc. The main objectives of biomedical instrumentation are to improve the quality of life, health care delivery, medical education and research, and disease prevention and management.
Basic components and principles of biomedical instruments
A typical biomedical instrument consists of four basic components: a transducer or sensor that converts a physical or chemical variable into an electrical signal; an amplifier or signal conditioner that modifies the signal to make it suitable for further processing; a processor or analyzer that performs mathematical operations on the signal to extract useful information; and a display or recorder that presents the information in a visual or audible form. The principles of biomedical instruments are based on various physical laws and phenomena such as Ohm's law, Kirchhoff's laws, Faraday's law, Coulomb's law, thermodynamics, optics, acoustics, electromagnetism, etc.
Classification and applications of biomedical instruments
Biomedical instruments can be classified according to various criteria such as function (measurement, monitoring, diagnosis, treatment, or improvement), modality (electrical, mechanical, thermal, optical, acoustic, or chemical), location (invasive, non-invasive, or minimally invasive), frequency (static, dynamic, or transient), complexity (simple, complex, or hybrid), reliability (accurate, precise, sensitive, specific, or robust), cost (low-cost, medium-cost, or high-cost), etc. The applications of biomedical instruments are numerous and diverse. They include cardiovascular system (heart rate, blood pressure, blood flow, cardiac output), respiratory system (breathing rate, lung volume, gas exchange), nervous system (brain activity, nerve impulses), muscular system (muscle contraction, relaxation), endocrine system (hormone levels), digestive system (food intake, absorption), urinary system (urine output), reproductive system (fertility), integumentary system (skin temperature), immune system (infection), skeletal system (bone density), etc.
