Warning
Explosive hazard — DO NOT use the oximeter in environment with inflammable gas such as
some ignitable anesthetic agents.
DO NOT use the oximeter while the testee measured by MRI and CT.
Please do not break the wristband, for fear it becomes out of use, or the unexpected drop of the
device which is due to the looseness of the wristband in the process of using. U sers who are allergic
to the wristband is not recommended to use it.
The person who is allergic to rubber can not use this device.
The disposal of scrap instrument and its accessories and packings (including battery , plastic
bags, foams and paper boxes) should follow the local laws and regulations.
Please check the packing before use to make sure the device and accessories are totally in
accordance with the packing list, or else the device may have the possibility of working abnormally.
Please choose the accessories and probe which are approved or manufactured by the
manufacturer, or else it may damage the device.

Attention
Attention
Attention
Keep the oximeter away from dust, vibration, corrosive substances, explosive materials, high
temperature and moisture.
If the oximeter gets wet, please stop operating it.
When it is carried from cold environment to warm or humid environment, please do not use it
immediately.
DO NOT operate keys on front panel with sharp materials.
High temperature or high pressure steam disinfection of the oximeter is not permitted. Refer to
User Manual in the relative chapter ( 7 .1) for instructions of cleaning and disinfection .
Do not have the oximeter immerged in liquid. When it needs cleaning, please wipe its surface
with medical alcohol by soft material. Do not spray any liquid on the device 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' SpO
2
and pulse rate, please clip the thick finger such as thumb and middle finger deeply
2
enought into the probe.
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 monment 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.
The device has normal useful life for three years since the first electrified use.
This device has the function of alarming, users can check on this function according to chapter
6.1 as a reference.
The device has the function of limits alarming, when the measured data is beyond the highest
or lowest limit, the device would start alarming automatically on the premise of the alarming function
is on.
The device has the function of alarming, this function can either be paused, or closed for good,
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.

The pulse oxygen saturation is the percentage of Hb O2in the total Hb in the blood, so-called the O
2
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 SpO
2
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 corresp onding 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' SpO
2
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 s aturation with the high
veracity and repetition.

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 Characteristic s of Reductive
Hemoglobin ( Hb ) and Oxyhemoglobin ( Hb O2) in glow & near-infrared zones. Operation principle of
the device is: Photoelectric O xyhemoglobin I nspection
T
echnology 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 per spective 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.
