2 Overview
The pulse oxygen saturation is the percentage of HbO
O
concentration in the blood. It is an important bio-parameter for the respiration. A numb er of
2
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 device is fashion and portable.It is only necessary for patient to put one finger into probe for
diagnosis,and display screen will directly show the measure value of pulse oxygen saturation
with the high veracity and repetition.
2.1 Features
A Operation is simple and convenient.
B Product is handsome and fashion,and easy to observe
C With two kinds of power supply mode(alternating current and internal electrical power source)
2.2 Major Applications and Scope of Application
The device 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.
2.3 Contraindications
The problem of overrating would emerge when t he patient is suffering from toxicosis
which caused by carbon monoxide,and the device is not recommended to be used under
this circumstance.
The person who is allergic to rubber can not use this device.

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.

to run the PC software.The functions such as uploading real time/memory data and change
device ID could be carried out by the software.Please refer to <SpO2 Assistant user manual> for
detail.
If the users choose to turn on the display function on computer, it would probably take
several seconds for the data to appear on the computer screen.(If there is no data on the
computer screen ,unplug data line,then repeat step E again .)
6.1.5 Charge
Connect the device to power supply with power line.
When the device is closed and the battery is charging up,short press power button and the
device will display dynamic charge icon ,it means that the device is charging up.When the
battery status is full,the charging has been finished.When the device is op en and the battery is

device is charging up.When the battery status is full,the charging has been finished.
6.2 Attention for Operation
A lease check the device before use, and confirm that it can work normally.
B The finger should be in a proper position (see the attached illustration of Figure 4 for
reference), or else it may result in inaccurate measure.
C The ray between luminescent tube and photoelectric receiving tube must get across subject’s
arteriole.
D The device should not be used at a location or limb tied with arterial canal or blood pressure
cuff or receiving intravenous injection.
E Ensure nothing, such as a plaster, can impede the light passage., or else it may result in
inaccurate measure of SpO2 ,pulse rate and PI.
F Excessive ambient light may affect the measure result. It includes fluorescent lamp, dual ruby
light, infrared heater, direct sunlight and etc.
G Exquisite action of the subject or extre me electrosurgical interference may also affect the
accuracy.
16
H Tes tee can not us e e na mel o r oth er ma ke up.
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 measure 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 thiosalicyl ic hemoglobin, and some with icterus problem, the SpO2 determination by this
device may be inaccurate.
C The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may als o be a major
factor resulted in serious error of SpO2 measu re.
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 measu re.
