What is Biomedical Engineering? - Types of Medical Engineering Technologies

Overview
Biomedical Engineering is one of the important branches of engineering, also known as “medical technology engineering”. Whatever the name is, this specialty focuses on one goal: the design and maintenance of devices used in the treatment of patients. 

Medical devices in their various classifications help doctors make an accurate diagnosis and then find appropriate treatment methods. This helps in the speed of recovery, and achieve positive results.



What is Biomedical Engineering?

Biomedical engineering is a science that combines biomedical as well as physiological and engineering sciences, such as computer engineering, electrical engineering, and mechanical engineering. 

Biomedical Engineering uses engineering foundations in building machines and equipment to heal patients. 

In each hospital or laboratory, there are many medical devices such as an MRI and an X-ray machine which helped improve the medical examination and led to a reduction in mortality. 
Modern medical instruments have also helped to increase doctors' ability to the medical examination.

The goal is to design medical and prosthetic devices; to understand the nature of diseases from all aspects and deal with them. 

Biomedical engineering is considered one of the most prestigious departments of the faculties of engineering. 
Therefore, those who engage in this specialization in many prestigious engineering colleges must obtain outstanding degrees in the first preparatory year.

The concept of medical engineering is an area of ​​study of biomedical engineering and technological concepts, which aims to develop the equipment and devices necessary for the delivery of health care. 

Organ transplantation, which aims to prevent, diagnose and treat diseases, in order to rehabilitate the patient and improve his health. 

The specialty of medical engineering is at the forefront of the medical revolution and its progress is achieved through interdisciplinary activities that integrate other sciences with engineering principles.

History of Medical Engineering - The Evolution of Bioengineering

The field of biomedical engineering began more than two centuries ago, through the use of some simple prosthetic devices, such as artificial teeth and crutches. Then technological discoveries began to come to light in this area. 
After sometimes, electrocardiography (ECG), diagnostic devices, and dialysis machines appeared. 

There is a comprehensive renaissance in this area; there are liposuction devices, laser devices for the treatment of farsightedness (hyperopia) and nearsightedness (myopia), sonar devices of all kinds, MRI, X-ray, CT, electronic microscopes, catheters, and endoscopes for treating vascular occlusion and stenting. 
Modernity is still going on, and there is something new every day.

What are the Different Fields of Biomedical Engineering?




Types of Biomedical Engineering
There are many divisions or classifications of biomedical engineering from an engineering perspective, the most important of which are:

Cell and tissue engineering: It is an important class of biomedical engineering, and contributes to the treatment of disorders or imbalances in human cells and tissues, from fine organs.

Medical electronics engineering: This classification is divided into two parts, bio-electrical effects, and bio-electrical signals, both of which depend on the adaptation of electricity science to serve patients, and diagnose their condition accurately.

Neural engineering: The human nervous system is manifold and intertwined.  

Neural engineering helps in the treatment and replacement of any defective component of the system. 
This is done through nanotechnology and computer applications, and also use sensors that help provide signals, which are directed to the brain.
To achieve responses for the organs of the body, highly sophisticated organs are designed to help treat many diseases caused by neurological dysfunction.

Genetic engineering: Genetic engineering is an important branch of biomedical engineering, the goal is to design precision devices; to identify the genetic effects in human infection of diseases, and then treat them.

Biomechanical Engineering: This classification is divided into biomechanics, and focuses on the treatment of all the negatives that may occur in the natural kinetics of humans, and biomechanics. 

This section focuses on the study of the transitions of vital substances found in the human body, and their impact on the creation of diseases and negative variables.



Types of Medical Engineering Technologies
Medical engineers have developed many technologies that help to facilitate all areas of life and contribute to saving a life, including:

Prosthetic devices: Transfemoral, transhumeral, transtibial and transradial prostheses or prostheses for human limbs and dentures.


Physiotherapy equipment: Physiotherapy equipment is very beneficial in such aspects of care as manual therapy, athletic taping and bracing, manipulation, acupuncture, exercise therapy, and electrotherapy.

Therapeutic equipment: such as dialysis devices, and electrical stimulation of the nerve through radiotherapy using X-rays.

Surgical devices: such as laser and robotic surgery.

Diagnostic and monitoring devices: Among the devices used in this category are typical instruments such as a stethoscope, lighting devices, and a pressure gauge, which includes external and internal pressure and fundus pressure and breathing pressure, and blood sugar measures.

Imaging devices: such as ultrasound, X-rays, magnetic resonance, computed tomography, scanning, electronic and nuclear medical devices, electrocardiographs, and brain scans.

Microscopes: They are the most prominent devices of biomedical engineering used in laboratories. There are many types, including traditional microscopes, and spectroscopy devices.


Biomedical Engineering Career Prospects

Career opportunities in the field of biomedical engineering are diverse. 
Many companies specialize in biomedical engineering; they import medical devices. The companies require medical engineering graduates for these porpuses. 
Biomedical engineers can be easily recruited into these types of companies, where they oversee the sale and maintenance of the equipment if necessary. 

There are centers for biomedical engineering research such as CMU BME Pittsburgh, PA and Competency-based medical education (CBME) in India that focus on innovators who can develop medical devices.

  1. Gain more value from your Internal Audits with these five steps
    ISO 9001 internal auditors play a critical role in the success of the system. ISO 9001 internal auditors provide inputs to Top Management for continual improvement of the system. Internal audits, given the nature, can be more detailed and as such usually go into depth considering the limited scope of the audit. For audits to add value internal auditors should be trained in identifying the adequacy of resources and controls in a process to meet the objectives as defined. The five steps as listed below are inputs to enhancing your internal audit program as also supplementing the ISO 9001 internal auditor training.
