Duty of Biomedical Engineers

• Designing medical instrument
• Contribute in the development, manufacturing and
  testing of medical products
• Maintain and enhance life of medical instrument
• Designing prostheses
• Designing replacement parts for people
• Creating systems to allow the handicapped to
  function, work and communicate
• Managing the technology in the hospital system.
• Saling biomedical instruments
• Etc.

Career Opportunities for Biomedical Engineers

• Biomedical engineers come from one of the
  traditional engineering disciplines, such as
  electrical or mechanical engineering.
• Biomedical engineers are exposed to many fields
  of study in engineering, medicine and biology.
  Due to this broad experience biomedical engineers
  find employment in

• Hospitals
• Clinics
• Diagnostic Centers
• Government bodies
• Industry
• Academic areas
• Research etc.

New fields of Biomedical Engineering

• Medical electronics
• Clinical engineering
• Rehabilitation engineering.

9
Medical Instrumentation

• Medical instrumentation is the application of
  electronics and measurement techniques to develop
  devices used in diagnosis and treatment of
  disease.

• Computers are an important and increasingly
  essential part of medical instrumentation
• Examples of medical instrumentation include
  heart monitors, microelectrodes, defibrillators,
  glucose monitoring machines etc.

10
Biomaterials

• Biomaterials are defined as the materials used
  for medical implantation includes both living
  tissue and artificial materials.

• Examples of biomaterials include
• Heart replacement valves
• Artificial lungs
• Artificial kidneys
• Dental adhesives
• Bone cement
• Replacement bones/joints
• Heart prosthetics
• Etc.

11
Biomaterials (cont.)

• Biomaterials must have following properties
• Nontoxic
• Non-carcinogenic
• Chemically inert (not reacting violently with the
  body's chemical composition)
• Stable
• Mechanically strong enough to withstand the
  repeated forces of a lifetime of use.

12
Human Physiology and Modeling

• Human Physiology is the study of the body and
  its functions in each of the different systems in
  any living body

• Modeling is used in the analysis of experimental
  data and in formulating mathematical descriptions
  of physiological events

Examples Biochemistry of metabolism and the
control of limb movements
13
Bio-Signal processing

• Collection and analysis of data (signal) from
  patients
• The manipulation and dissection of the data or
  signal provides the physician and experimenter
  the vital information on the condition of the
  patient.
• Biomedical Engineers apply signal-processing
  methods to the design of medical devices that
  monitor and diagnose certain conditions in the
  human body.
• Examples Heart arrhythmia detection software and
  brain activity

14
Medical Imaging

• Medical Imaging combines knowledge of a unique
  physical phenomenon (sound, radiation, magnetism
  etc.) with high-speed electronic data processing,
  analysis and display to generate an image.

• Examples
• Magnetic Resonance Imaging (MRI)
• Ultrasound and computed tomography (CT).

15
Biomechanics

• Biomechanics applies both fluid mechanics and
  transport phenomena to biological and medical
  issues.
• It includes the study of motion, material
  deformation, flow within the body, as well as
  devices, and transport phenomena in the body,
  such as transport of chemical constituents across
  biological and synthetic media and membranes.
• Efforts in biomechanics have developed the
  artificial heart, replacement heart valves and
  the hip replacement.

16
Rehabilitation Engineering

• Rehabilitation engineering is the systematic
  application of engineering sciences to design,
  develop, adapt, test, evaluate, apply, and
  distribute technological solutions to problems
  confronted by individuals with disabilities.
• Functional areas of rehabilitation engineering
  may include mobility, communications, hearing,
  vision, and cognition, and activities associated
  with employment, independent living, education,
  and integration into the community.
