When your finger is plugged into the
Oximeter, your nail surface must be
upward.
Haemoglobin Saturation is percentage of Oxyhe-
moglobin (HbO
2
) capacity, compounded with
oxygen, by all combinativable haemoglobin (Hb)
obin (HbO
2
) capacity in blood. In other words, it is
consistence of Oxyhemoglobin in blood. It is a very
important ecological parameter for Respiratory
circulation System. Many respiratory diseases can
result in haemoglobin Saturation being lowered in
human blood. Moreover, the following factors can
also lead to problems in oxygen supply, so that
human haemoglobin saturation might be reduced:
Automatic Organic Regulation Malfunction caused
by Anesthesia, Intensive Postoperative Trauma,
hurts resulted in by some medical examination and
etc. In the situation, illnesses, such as light head,
asthenia, vomitory and etc, might happen to
patients and even endanger the patient’s life.
Therefore, it is very important to know Hemoglobin
saturation of patient timely in clinical medical
aspects. So that doctors can find problems in time.
The Finger type Pulse Oximeter features in small
volume, low power consumption, convenient opera-
tion and being portable. It is only necessary for
patient to put one of his fingers into a finger type
photoelectric sensor for diagnosis, and a display
screen will directly show measured value of
hemoglobin Saturation. It has been proved in
clinical experiments that it features in rather high
precise and repeatability.
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 (R Hb) and Oxyhemoglobin (O
2
Hb) in
glow and near-infrared zones. Operation principle
of the instrument is Photoelectric Oxyhemoglobin
inspection Technology is adopted in accordance
with Capacity Pulse Scanning and Recording
Technology, so that two beams of different
wavelength of lights (660nm glow and 940nm near
infrared light) 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 two groups of
LEDs through process in electronic circuits and
microprocessor.
1. Do not use the pulse oximeter in an MRI or CT
environment.
2. Do not use the pulse oximeter in situations where
alarms are required. The device has no alarms.
3. Explosion hazard: Do not use the pulse oximeter
in an explosive atmosphere.
4. The pulse oximeter is intended only as an adjunct
in patient assessment. It must be used in conjunction
with other methods of assessing clinical signs and
symptoms.
5. Check the pulse oximeter sensor application site
frequently to determine the positioning of the sensor
and circulation and skin sensitivity of the patient.
6. Do not stretch the adhesive tape while applying
the pulse oximeter sensor. This may cause
inaccurate read the manual.
7. Before use, carefully read the manual.
8. The pulse oximeter has no SpO2 alarms; it is not
for continuous monitoring, as indicated by the
symbol.
9. Prolonged use or the patient’s condition may
require changing the sensor site periodically.
Change sensor site and check skin integrity,
circulatory status, and correct alignment at least
every 4 hours.
10. Inaccurate measurements may be caused by
autoclaving, ethylene oxide sterilizing, or immersing
the sensors in liquid may cause inaccurate readings.
11. Significant levels of dysfunctional hemoglobins
(such as carbonxy-hemoglobin or methemoglobin)
12. Intravascular dyes such as indocyanine green or
methylene blue.
13. SpO2 measurements may be adversely affected
in the presence of high ambient light. Shield the
sensor area (with a surgical towel, or direct sunlight,
for example) if necessary.
14. Excessive patient movement
15. High-frequency electrosurgical interference and
defibrillators
16. Venous pulsations
17. Placement of a sensor on an extremity with a
blood pressure cuff, arterial catheter, or intravascular
line.
18. The patient has hypotension, severe vasocon-
striction, severe anemia, or hypothermia
19. The patient is in cardiac arrest or is in shock
20. Fingernail polish of false finernails may cause
inaccurate SpO2 readings.
Follow local ordinances and recycling instructions
regarding disposal or recycling of the device and
device components, including batteries.
1 Operation of the product is simple and conve-
nient
2 The product is small in volume, light in weight
(total weight is about 50g including batteries) and
convenient in carrying.
3 Power consumption of the product is low and
product is low and the two originally-equipped two
AAA batteries can be operated continuously for 30
hours.
4 Low voltage warning will be indicated in visual
window when battery voltage is so low that normal
operation of the oximeter might be influenced.
5 The product will automatically be powered off
when no signal is in the product for longer than 8
seconds.
The finger type Oximeter can be used to
measure human Haemoglobin Saturation and
heart rate through finger. The product is suitable
for use in family, hospital (including clinical use in
internist/ surgery, Anaesthesia, pediatrics,
intensive care and etc.) Oxygen Club, social
medical organizations, physical care in sports (It
can be used before or after sports. Operation in
sport procedure is not recommended) and etc.
The product is not suitable to monitor patient
continuously.
1 Installing two AAA batteries into battery cassette
before covering its cover.
2 Nip the clamp as diagram
3 Plug one of fingers into rubber hole of the
Oximeter (it is best to plug the finger thoroughly)
before releasing the clamp
4 Press the switch button once on front panel.
5 Your finger do not tremble during the Oximeter is
working. Your body is not recommended in moving
status.
6 Read correspondent datum from display screen.
7 Six display modes
After turn on the oximeter, each time you
press the power switch, the oximeter will
switch to another display mode, there are
6 display modes shown as follows:
When you press the power switch for a long
time (more than on second), the brightness
of the oximeter will be changed by degrees,
there are 10 levels on brightness; the
default level is level four.
Declaration:
Please use the medical alcohol to
clean the rubber touching the finger inside of
Oximeter, and clean the test finger using
alcohol before an after each test. (The rubber
inside os the Oximeter belongs medical rubber,
which has no toxin, and no harmful to the skin
of human being).
7. Brief Description of Front Panel
It is apparent the heart rate bargraph display
corresponds with pulse rate.
