Light
waves
and
ultrasound
will
replace
needles
in
this
new
glucometer.
This
glucometer
indirectly
measures
the
glucose
levels
of
a
patient's
arterial
blood
as
opposed
to
measuring
it
directly
through
a
blood
sample.
This
apparatus
generates
a
combination
of
light
waves
and
ultrasound
from
a
probe
that
is
placed
under
the
tongue
of
person
to
measure
vital
signs
on
the
patient.
On
the
tip
of
the
probe
there
are
2
sets
of
small
light-emitting
diodes
(LEDs).
The
first
LED
emits
light
in
the
red
spectrum
of
light
and
the
second
set
of
LEDs
emits
infrared
(IR)
light
wavelengths.
Also
at
the
end
of
the
probe
there
is
an
ultrasound
transducer/detector
used
to
capture
the
reflection
signature
of
the
sound
waves
that
occur
in
the
saliva
medium
of
the
mouth.
The
emitted
red
(R)
and
infrared
(IR)
lights
from
the
probe
bounce
from
the
patients
tongue
and
the
reflected
light
signals
are
received
by
a
photo
detector.
The
R/IR
ratio
together
with
the
sound
waves
is
computed
to
reveal
the
amount
of
glucose
in
the
patient’s
blood.
The
amount
light
absorbed/reflected
is
different
and
it
varies
depending
on
what
it
encounters:
tongue
tissues,
saliva,
dead
skin
cells
and
most
importantly
by
blood
(both
venous
and
arterial).
The
combined
ultrasound
waves
can
distinguish
the
signals
that
correspond
to
pulsating
arterial
blood
and
allow
the
photo
detector
to
look
at
only
these
variable
absorptions
of
light
waveforms.
This
new
generation
of
glucometer
using
light
and
sound
replaces
needles
in
diabetic
glucose
monitoring
and
will
permit
a
continuous
signal
feedback
to
control
insulin
pumps.
