use the standard accessories.

2. OVERVIEW
The pulse oxygen saturation is the percentage of HbO2in the total Hb in the
blood, so-called the O2concentration in the blood. It is an important bio-pa-
rameter for the respiration. A number of diseases relating to respiratory system
may cause the decrease of SpO2in 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 difculty of oxygen supply in human body, and the corresponding symp-
toms would appear as a consequence, such as vertigo, impotence, vomit etc.
Serious symptoms might bring danger to human’s life. Therefore, prompt infor-
mation of patients’ SpO2is of great help for the doctor to discover the potential
danger, and is of great importance in the clinical medical eld.
The device is fashion and portable.It is only necessary for patient to put one n-
ger 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
AOperation is simple and convenient.
BProduct is handsome and fashion, and easy to observe
CWith two kinds of power supply mode(alternating current and internal elec-
trical 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 nger. The product is suitable for being used in family, hospital,
oxygen bar, community healthcare, physical care in sports (It can be used be-
fore 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 the patient is suf-
fering 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 Absorp-
tion Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin (HbO2)
in glow & near-infrared zones. Operation principle of the device is: Photoelec-
tric Oxyhemoglobin Inspection Technology is adopted in accordance with Ca-
pacity Pulse Scanning & Recording Technology, so that two beams of different
wavelength of lights can be focused onto human nail tip through perspective
clamp nger-type sensor. Then measured signal can be obtained by a photo-
sensitive element, information acquired through which will be shown on screen
through treatment in electronic circuits and microprocessor.

6.1.4 PC software operation
Please connect the device to the computer by data line, then double click
“SpO2Assistant” icon 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 <SpO2Assistant 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, un-
plug data line, then repeat step E again .)
6.1.5 Charge
Connect the device to power supply with power line, and make the power
button on.
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 charg-
ing has been nished. When the device is open and the battery is charg-
ing up, the battery status icon on the right top will display dynamically.
It means that the device is charging up.
When the battery status is full, the charging has been nished.
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.
18

19
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 fluores-
cent lamp, dual ruby light, infrared heater, direct sunlight and etc.
G Exquisite action of the subject or extreme electrosurgical interference may
also affect the accuracy.
H Testee can not 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 pulsat-
ing 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 SpO2waveform (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 meth-
ylene blue, indigo green and acid indigo blue), or carbon monoxide he-
moglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin, and
some with icterus problem, the SpO2determination by this device may be
inaccurate.
C The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may
also be a major factor resulted in serious error of SpO2measure.
D As the SpO2value serves as a reference value for judgment of anemic an-
oxia and toxic anoxia, some patients with serious anemia may also report
good SpO2measure.
7. MAINTENANCE, 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 Maintenance
A Please clean and disinfect the device before use according to the User
Manual (7.1).
