directly.
When cleaning the device with water, the temperature should be lower than 60℃.
As to the fingers which are too thin or too cold, it would probably affect the normal
measure of the patients' SpO2 and pulse rate, please clip the thick finger such as thumb
and middle finger deeply enough into the probe.
The pulse oximeter can be used to adult or infant. Whether the device is used to adult or
infant, it depends on the probe selected.
The update period of data is less than 5 seconds, which is changeable according to
different individual pulse rate.
Please read the measured value when the waveform on screen is equably and steady-
going, This measured value is optimal value. And the waveform at the moment is the
standard one.
If some abnormal conditions appear on the screen during test process, pull out the finger
and reinsert to restore normal use.

(default setting) for good. This function could be turned on through menu operation if
you need. Please check the chapter 6.1 as a reference.
The device may not work for all patients. If you are unable to achieve stable readings,
discontinue use.
2. Overview
The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2
concentration in the blood. It is an important bio-parameter for the respiration. A number of diseases
relating to respiratory system may cause the decrease of SpO2 in the blood, furthermore, some other
causes such as the malfunction of human body's self-adjustment, damages during surgery, and the
injuries caused by some medical checkup would also lead to the difficulty of oxygen supply in
human body, and the corresponding symptoms would appear as a consequence, such as vertigo,
impotence, vomit etc. Serious symptoms might bring danger to human's life. Therefore, prompt
information of patients' SpO2 is of great help for the doctor to discover the potential danger, and is of
great importance in the clinical medical field.
The Pulse Oximeter features in small volume, low power consumption, convenient operation and
being portable. It is only necessary for patients to put one of his fingers into a probe for diagnosis,
and a display screen will directly show the measured value of pulse oxygen saturation with the high
veracity and repetition.
2.1 Features
A. Operation of the product is simple and convenient.
B. The product is small in volume, light in weight and convenient in carrying.

Medical Test Supply
C. Low power consumption
2.2 Major applications and scope of application
The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through
finger. The product is suitable for being used in family, hospital, oxygen bar, community healthcare,
physical care in sports (It can be used before or after doing sports, and it is not recommended to use
the device during the process of having sport) and etc.
The pro lem of overrating would emerge when the patient is suffering from toxicosis
which caused y car on monoxide, the device is not recommended to e used under this circu
mstance.

Operating Environment
a) Temperature:10℃～40℃
b) Relative Humidity :30%～75%
c) Atmospheric pressure:700hPa～1060hPa
3. Principle
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 (HbO2) in glow & near-infrared zones. Operation principle of
the device 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.

If the users choose to turn on the synchronizing display function on computer, it would
pro a ly take several seconds for the data to appear on the computer screen.(If there is no
data on the computer screen ,unplug USB data line , then repeat step "E" again .)
F. Charge
There are two kinds of charging methods:
a) Connect the device with computer by data line, then the device should be under charging state.
) Connect the device with power supply by power adaptor, then the device should be under
charging state.
c) The five status of battery power are shown as follows:
d） When charging the battery in the state of power off, the sign of battery status still exists on the
screen, but it will disappear in about 60 seconds for saving power. However, the sign will appear
again if you press any button(power on/off excluded) at this moment.
If the alarm function is on, the device will provide high-priority alarm signal when the
attery is in low power status .Intermittent alarm will occur and the attery icon turns red in
the state of flashing.
High priority indicating that immediate operator response is required.
6.2 Attention for operation
A. Please check the device before using, and confirm that it can work normally.
B. The finger should be in a proper position (see the attached illustration of figure 3 for reference), or
else it may result in inaccurate measure.
C. The SpO2 sensor and photoelectric receiving tube should be arranged in a way with the subject’ s
arteriole in a position there between.
D. The SpO2 sensor should not be used at a location or limb tied with arterial canal or blood pressure
cuff or receiving intravenous injection.
E. Do not fix the SpO2 sensor with adhesive or else it may result in venous pulsation and inaccurate
measure of SpO2 and pulse rate.
F. Excessive ambient light may affect the measuring result. It includes fluorescent lamp, dual ruby
light, infrared heater, direct sunlight and etc.

G. Strenuous action of the subject or extreme electrosurgical interference may also affect the
accuracy.
H. Testee cannot use enamel or other makeup.
I. Please clean and disinfect the device after operating according to the User Manual(7.1).
6.3 Clinical restrictions
A. 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 SpO2 waveform (PLETH) will decrease. In this
case, the measurement will be more sensitive to interference.
B. 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 SpO2 determination by this monitor
may be inaccurate.
C. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor
blamed for serious error of SpO2 measure.
D. As the SpO2 value serves as a reference value for judgment of anemic anoxia and toxic anoxia,
some patients with serious anemia may also report good SpO2 measurement.
7 Maintain, transportation and storage
7.1 Cleaning and Disinfecting
Using medical alcohol to disinfect the device, nature dry or clean it with clean soft cloth.
7.2 Maintain
A. Please clean and disinfect the device before using according to the User Manual(7.1).
