Introduction to Biomedical Instruments Biology
It deals with wide spectrum of
Life sciences i.e. plants, animals, Insects or
in nutshell all living organisms.
Study of only human being out of these is
Called Medical Science.
If we want to study Engineering principles
in medical science the resulting subject will
be Medical Engineering.
If we wish to cover more animals on the
earth, the science will be Bio- Medical
Engineering.
Engineering or Instrumentation is defined
as science of using measurements.
SCOPE – 1
The study of Engineering principles from Biomedical Engineering involves following interests :
To understand mechanisms, efficiencies & physical changes of various subsystems of the body.
To evolve an instrumentation system for diagnosis, therapy and supplementation of body function.
To obtain qualitative & quantitative knowledge through different instruments which can help for analysis of disorders, and further the Biomechanics of the cure process.
SCOPE – 2
The study of medical principles from Biomedical engineering involves following interests.
To understand Bio-Chemico-Electro – Thermo- Hydraulico- Pneumatico- Physico- Magnato- Mechano – Dynamic actions and changes of various sub systems of the body in normal states.
To Understand above actions & changes in various sub systems of the body in abnormal states i.e. in Pathology.
To obtain qualitative & quantitative knowledge of what drug does to the body ( Pharmacodynamics ) and what body does to the drug
( Pharmacokinetics ) during and after prescription of the drug.
BREAK THROUGH
A major break through in the form of ECG was invented by Dutch scientist in 1930.
It was the first step forward towards modernization of Biomedical Instrumentation.
Monitoring Instruments
1. Bed – side monitor
2. Bio – monitor
3. Foetal monitor
BIO METRICS
It is the branch of science that includes measurements of
physiological variables and parameters.
BMI provides the tools by which these measurements can be achieved.
SENSITIVITY
The sensitivity of an instrument determines how small a variation of a variable or parameter can be really reliably measured.
LINEARITY
The degree to which variations in the output of an instrument follow input variations is referred to as the linearity of the device.
ISOLATION
Electrical Isolation is to be made for avoiding interference between different instruments used simultaneously. It can be achieved by using magnetic or optional coupling technique or using radio tetermetry.
Telemetry is also used where movement of the person or animal to be measured.
