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.
HISTORY
Stethoscope, the first medical instrument of its own kind was invented in by French Physician Laennec.
Today in 1997 even at a district place in India computer aided tomography equipment is easily available.
For many years, the doctors, vaidyas depended upon pulse rate, thermometer and stethoscope , however today hundreds of sophisticated Biomedical instruments are available.
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.
RANGE
The range of an instrument is generally considered to include all the levels of input amplitude & frequency over which the device is expected to operate.
The objective is to provide an instrument that will give a usable reading from the smallest expected value of the variable or parameter being measured to the largest.
