2. GLUCOMETER
• A glucometer is a
medical device used for
measuring approx level
of glucose in the blood.
3. Working principle of glucometer
• Determines the of glucose conc. in the blood.
• Based on electrochemical technology ,they
use electrochemical test strips to perform
measurement.
• A small drop of blood to be tested is placed on
a disposable test strip that the glucometer
uses for glucose measurement.
4. • Strip contain enzyme called glucose oxidase.
This enzyme reacts with glucose in blood
sample and creates acid called gluconic acid.
• Gluconic acid +ferricyanide=ferrocyanide
• Once ferrocyanide is formed ,device run an
electronic current through blood sample on
strip.
5. • This current is then able to read the
ferrocyanide and determine how much
glucose is in sample of blood on testing strip.
• The number is then displayed on screen of
glucose testing meter.
12. Minimum invasive devices
• Insertion of sensor into
subcutaneous tissue
underneath skin.
• Utilized for real time
monitoring
• 1.Scan Bo:60sec Non
invasive Finger
measurements.
13. • 2.Sugar B-UK based
• Tiny peel place patch
that could be replaced
with new one.
• Transmittor in device
from patch send
wireless reading to the
smartphone via
bluetooth every 5min.
14. • Free libre 2and 3
• Wearable sensor on
upper arm
• Optical alarm feature
when glucose level
exceeds threshold range
