1.4
Indication
for
Use
The Pulse Oximeter is a non-invasive device intended for the spot-check of saturation of arterial
hemoglobin(SpO2) and the pulse rate of adult in home use environments.This device is not intended for
continuous monitoring.The device can be multi-used.
Solely for use with sporting and aviation activities.
2 Overview
The
pulse
oxygen
saturation
is
the
percentage
of
HbO
2
in
the
total
Hb
in
the
blood,
so-called
the
O
2
concentration
in
the
blood.
It
is
an
important
bio-parameter
for
respiration.
For
the
purpose
of
measuring
the
SpO
2
more
easily
and
accurately,
our
company
developed
the
Pulse
Oximeter.
At
the
same
time,
the
device
can
measure
the
pulse
rate
.
The
Pulse
Oximeter
features
small
size,
low
power
consumption,
convenient
operation
and
being
portable.
It
is
only
necessary
for
users
to
put
one
finger
into
the
device
to
quickly
get
a
reading.
2.1
Features
Operation of the product is simple and convenient.
The product is small in volume, light in weight (total weight is about 50 g including batteries) and
convenient to carry.
Power consumption of the product is low and the two originally equipped AAA batteries can be operated
continuously for 20 hours.
The product will enter standby mode when no signal is in the product within 5 seconds.
Display direction can be changed automatically,easy to view.
2.2 Major Applications and Scope of Application
The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through finger, and
indicate the pulse intensity by the bar-display.
The
product
is
not
suitable
for
use
in
continuous
monitoring
of
home users
The
problem
of
overrating
would
emerge
occur
when
the
user
is
suffering
from
toxicities
caused
by
carbon
monoxide,
the
device
is
not
recommended
to
be
used
under
this
circumstance.

3 Principle and Caution
3.1 Principle of Measurement
Principle of the Oximeter is as follows: An experience formula of data process is established taking use of Lambert
Beer Law according to Spectrum Absorption Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin
(HbO
2
) in glow & near-infrared zones. Operation principle of the instrument is: Photoelectric Oxyhemoglobin
Inspection Technology is adopted in accordance with Capacity Pulse Scanning & Recording Technology, so that
two beams of different wavelength of lights can be focused onto human nail tip through perspective clamp
finger-type sensor. Then measured signal can be obtained by a photosensitive element, information acquired
through which will be shown on screen through treatment in electronic circuits and microprocessor.
Figure 1 Operating principle
3.2 Caution
1.
The
finger
should
be
placed
properly
(see
the
attached
illustration
of
this
manual,
Figure
5),
or
else
it
may
cause
inaccurate
measurement.
2.
The
SpO
2
sensor
and
photoelectric
receiving
tube
should
be
arranged
in
a
way
with
the
subject’s
arteriole
in
a
position
there
between.
3.
The
SpO
2
sensor
should
not
be
used
at
a
location
or
limb
tied
with
arterial
canal
or
blood
pressure
cuff
or
receiving
intravenous
injection.
4.
Make
sure
the
optical
path
is
free
from
any
optical
obstacles
like
rubberized
fabric.
5.
Excessive
ambient
light
may
affect
the
measuring
result.
It
includes
fluorescent
lamp,
dual
ruby
light,
infrared
heater,
direct
sunlight
etc.
6.
Strenuous
action
of
the
subject
or
extreme
electro
interference
may
also
affect
the
accuracy.
7.
User
can
not
use
fingernail
polish,
fake
nails
or
other
makeup.
3.3
Clinical
Restrictions
1.
As
the
measure
is
taken
on
the
basis
of
arteriole
pulse,
substantial
pulsating
blood
flow
of
subject
is
required.
For
a
subject
with
weak
pulse
due
to
shock,
low
ambient/body
temperature,
major
bleeding,
or
use
of
vascular
contracting
drug,
the
SpO
2
waveform
(PLETH)
will
decrease.
In
this
case,
the
measurement
will
be
more
sensitive
to
interference.
2.
For
those
with
a
substantial
amount
of
staining
dilution
drug
(such
as
methylene
blue,
indigo
green
and
acid
indigo
blue),
or
carbon
monoxide
hemoglobin
(COHb),
or
methionine
(Me+Hb)
or
thiosalicylic
hemoglobin,
and
some
with
icterus
problem,
the
SpO
2
determination
by
this
monitor
may
be
inaccurate.
3.
The
drugs
like
dopamine,
procaine,
prilocaine,
lidocaine
and
butacaine
may
also
be
a
major
factor
blamed
for
serious
error
of
SpO
2
measure.
4.
As
the
SpO
2
value
serves
as
a
reference
value
for
judgement
of
anemic
anoxia
and
toxic
anoxia,
some
users
with
serious
anemia
may
also
report
good
SpO
2
measurement.
