What is biomedical engineering?! Biomedical Engineering, also known as Medical Technology Engineering, is the science concerned with studying the human body from an engineering perspective. It serves as a bridge between medicine and engineering, as a biomedical engineer must understand the human body in order to design compatible prosthetic limbs, artificial organs, and medical devices.
Biomedical engineering is considered one of the newest branches of engineering that emerged alongside the advancement of modern medicine. In the past, doctors handled diagnosis, treatment, and even pharmaceutical production on their own. Today, biomedical engineers have become essential partners to physicians in diagnosis, treatment, and patient monitoring.
Due to the urgent need to develop medical devices and equipment that improve patient health and accelerate recovery, specialists from fields other than medicine became involved in designing such technologies, including electrical engineers, mechanical engineers, and computer engineers.
These engineers also needed knowledge of medical sciences such as anatomy and physiology in order to understand how the body’s systems function and apply their engineering expertise to improve medical equipment. As a result, the need arose for a professional who possesses partial expertise in all these disciplines and can effectively collaborate with doctors without replacing any of them.
Types of Medical Devices in Biomedical Engineering __ What is Biomedical Engineering
Biomedical engineering deals with two major categories of medical devices:
Diagnostic Medical Devices
Examples include ultrasound machines.
The most important diagnostic equipment are those used for imaging and visualization inside the patient’s body, which fall under the field of medical imaging. Biomedical engineers who develop these devices must possess extensive knowledge in biology, medicine, engineering, and mathematics. These devices can pose serious risks to human life if used incorrectly or excessively.
Examples include:
- Magnetic Resonance Imaging (MRI) scanners
- Computed Tomography (CT) scanners
- X-ray imaging devices
- Gamma cameras
- Ultrasound imaging systems
- Mammography devices
- Devices for recording signals from the heart, brain, muscles, eyes, and more
Therapeutic Medical Devices
Examples include chemotherapy devices and wave-based therapy systems.
It is commonly believed that biomedical engineering is limited to medical equipment and maintenance; however, the field extends far beyond that to include hospital management, prosthetics, artificial organs, and many other applications.
Biomedical engineering applies physics, chemistry, mathematics, and engineering fundamentals to the study of biology (mainly the human body) in order to better understand diseases and develop advanced healthcare solutions.
Examples include:
- Pacemakers (artificial cardiac rhythm devices)
- Defibrillators (electric shock devices)
- Medical endoscopes
- Dialysis machines (artificial kidneys)
- Artificial hearts
- Cobalt therapy devices
- Artificial blood vessels
- Other medical technologies
One of the latest innovations is a medical system directly connected to the patient’s body through sensors that measure vital signs such as heart rate, body temperature, and breathing rate. These signals are continuously transmitted to a receiver located in the patient’s home.
If the patient experiences an emergency, such as a heart attack, sudden changes in these indicators trigger an alert sent to a nearby hospital for immediate medical assistance. Elderly people are among the primary users of this technology.
Artificial Organs
Artificial organs are medical devices that can replace damaged biological organs in humans or animals, such as prosthetic limbs. The surfaces of these organs may be made from silicone or titanium. Artificial organs often contain electronic circuits and can move.
The latest prosthetic limbs are connected to nerves and move according to neural signals from the brain. Individuals who suffered severe injuries during wars commonly use these advanced prosthetics. One of the most widespread artificial implants is the artificial hip joint.
Artificial organs are not limited to prosthetic limbs only; scientists have recently developed artificial livers as well.
Examples of artificial organs include:
- Artificial hearts
- Artificial pancreases
- Artificial livers
