Chapter 1 Blood Glucose Monitoring System
1.1 Introduction
The blood glucose monitoring system, model HEA-230 uses the state-of-
art bio-electrochemistry detecting technology, it only needs approximately
1 μL fresh capillary blood for one testing. Blood glucose concentration
result will be showed in 5 seconds after you apply a blood sample into
the test zone. It could help diabetics monitoring their glucose level, and
is intended for blood glucose monitoring by people with diabetics and
healthcare professionals. Please read instruction manual carefully before
using.
HEA-230 is an in vitro diagnostic medical device for self-testing. By
capillary action, test sample will automatically ll up the reaction zone by
inhalation from the front channel.
Intended Use
The Blood Glucose Monitoring System, model HEA-230, is an in vitro
diagnostic medical device intended for the quantitative measurement of
glucose in fresh capillary whole blood samples drawn from the ngertips.
Testing is done outside the body. It is designed for self-testing to monitor
the effectiveness of diabetes control. The device should not be used for
screening or diagnosis of diabetes or for testing neonates.Principle of the
method
Principle of the method
By auto-filled mechanism, the volume of the sample can be precisely
controlled. The blood glucose test strip is a kind of electrochemical
biosensor. When the blood sample reacts with the strip, the glucose
meter provides a voltage and the number of electrons produced by the
reaction is detected.The current obtained from the blood glucose meter
can be calculated by the internal conversion formula and be translated to
the concentration of the sample.
Warning: The glucose results provided by this system are only for
the reference; never make signicant changes in your diabetes treatment
program without consulting physicians.
