Warnings
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 Patient is under MRI or CT scanning. This
device is NOT MRI Compatible.
Cautions
Discomfort or pain may occur if using the sensor of this device continuously on the
same location for a long time, especially for the patients with poor microcirculation.
It is recommended that the Oximeter should not be applied to the same location
for longer than 2 hours or less if any abnormal condition is found. Frequently check
and re-position the Oximeter sensor.
Misapplication of a SpO2 probe with excessive pressure for prolonged periods can
induce pressure injury.
Place the SpO2 probe on the finger tightly will cause venous pulse and effect blood
circulation, and lead to interstitial edema, hypoxia and inaccurate measurement.
Biocompatibility tests have been performed on all the applied parts, some excep-
ENGLISH 38
tional allergic patients may still have anaphylaxis. Do not apply to those who have
anaphylaxis.
For the individual patients, there should be a more prudent inspecting in the placing
process. The sensor can not be placed on the edema and tender tissue.
The local law should be followed when disposing of the expired device or its acces-
sories.
DO NOT operate in the environment where strong electro-magnetic interference
exists, such as radiogram, television, radiophone, etc.
Please pay attention to the SpO2 probe cable while using to avoid strangulating
patient.
Notes
Keep the oximeter away from dust, vibration, corrosive substances, explosive ma-
terials, high temperature and moisture.
If the Oximeter gets wet, please stop operating it and do not resume operation until
it is dry and checked for correct operation. When it is carried from a cold environ-
ment to a warm and humid environment, please do not use it immediately. Allow at
least 15 minutes for the Oximeter to reach ambient temperature.
DO NOT operate the button on the front panel with sharp materials or sharp point.
DO NOT use high temperature or high pressure steam disinfection on the oximeter
and probes. Refer to related chapter for instructions regarding cleaning and disin-
fection.
The intended use of this device is not for therapy purpose.
The equipment is IP22 with protection against harmful solid foreign objects and
ingress of liquid. So that means the equipment is protected against solid foreign
objects of 12.5mm and greater, and protected against vertically falling water drops
when enclosure tilted up to 15°.
Please pay attention to the effects of lint, dust, light (including sunlight), etc.

Probe Cover
Operation procedure:
1. Connect the infrared temperature probe to the connector on the upper side of
device marked with “TEMP”.
2. When the screen shows as the big display screen in figure 3.2 and the temperature
unit “°C” is blinking, the user can begin to take the measurement.
3. Insert the tip of the temperature probe into the earhole and press the measuring key
to start the measurement. A short beep means the measurement has finished and
the result will be displayed on the big display screen on temperature probe and the
display screen of the Oximeter.
47 ENGLISH
Nota:
• If the temperature probe detects a hardware failure, the display screen on the infra-
red temperature probe will show “Err” and will not enter into measurement mode.
• The infrared temperature probe will switch to standby state automatically if there is
no operation for 1 minute. If a further measurement is needed, press the measuring
key and repeat step 2 and step 3.
• Normal body temperature varies depending on the position/area the measurement
is taken from. The following table shows the varying temperature ranges of the dif-
ferent body positions.

Description:
• During measurement, if the finger is not inserted properly, or the probe is not con-
nected or the probe is off from the finger, then “Check Probe” message prompts and
keeps blinking on the screen, and “bibibi...” alert sound appears simultaneously.
Alert sound is sustaining for about 3 minutes, and if there is no any key operation in
this period, then the device will power off automatically (if the auto power off func-
tion is enabled).
• During measurement, longtime pressing Auto-rotate/Up key “ ”, then
the Auto-rotate white icon “ ” appears on the upper right corner of the
49 ENGLISH
screen, it means the auto rotation function is enabled, if you place this oxime-
ter horizontally, then the display shows in horizontal, as shown in figure 4.2B.
• Sound indicator “ ” means that the global sound is disabled, the user can enable
• If the global sound is enabled by longtime pressing “ ”, key, then during the
measurement, over-limit alert event or probe off event can activate the audible alert.
Refer to Section 6.2 for detailed alert indication sound.

• During data uploading, the user can not do any operation on the oximeter.
When the wireless transmission function is on, the Handheld Pulse Oximeter can com-
municate with a host (such as computer or mobile) for viewing and management.
a. Open the host’s wireless function and procedure and start to scan the SP-20 Oxi-
meter.
b. The host will pair with the SP-20 Oximeter at a moment.
c. After connecting, the host can display and manage the measurement data of SP-20
by wireless
61 ENGLISH
The pairing and transmitting distance of wireless function is 8 meters in the normal.
If the host can’t pair with the SP-20, you will try to narrow the distance between the
host and SP-20.
The SP-20 can pair and transmit with the host under the wireless coexistence envi-
ronment, but other wireless device may still interface with pairing and transmission
between the host and the SP-20 device under uncertain environment. If the host and
the SP-20 display inconsistent, you may need to change the environment.

age of the latest calculated parameters. The reading value of SpO2 and PR on the
oximeter is updated every second, and the displayed plethysmogram is a normal-
ized waveform. If the signal is no integral (such as with too much noise, or poor
signal to noise ratio or signal is lost), then the SpO2 and PR will be identified as an
invalid value, that’s to say, the numeric reading will disappear and be displayed as
“--” instead.

Note: The oximeter is calibrated in the factory before sale, and there is no need for
user to calibrate again.

During the measurement, if the measured value exceeds the preset value, the alert
beeping sound will be activated, the value that is over-limit will blink at the same time.
“ ” appears on the upper right corner of the screen), but the over-limited value
still keeps blinking. when the current alert event ends or a new type of alert event
occurs, then the status of audible alert reset will be ended (that’s to say, the alert
sound can be generated when an alert event occurs, and icon “ ” appears on the
upper right corner of the screen).
• When the global sound is enables, then the longtime pressing “ ” key cam
disable the global sound, and the sound icon becomes “ ”. Longtime pressing
“ ” key again can enable the global sound.

2 Principle of Measurement
Based on Lamber-Beer law, the light absorbance of a given substance is directly pro-
portional with its density or concentration. When the light with certain wavelength
emits on human tissue, the measured intensity of light after absorption, reflecting and
attenuation in tissue can reflect the structure character of the tissue by which the light
passes. Due to that oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin
(Hb) have different absorption character in the spectrum range from red to infrared
light (600nm~1000nm wavelength), by using these characteristics, SpO2 can be de-
termined. SpO2 measured by this oximeter is the functional oxygen saturation -- a
percentage of the hemoglobin that can transport oxygen. In contrast, hemoximeters
report fractional oxygen saturation – a percentage of all measured hemoglobin, in-
cluding dysfunctional hemoglobin, such as carboxyhemoglobin or metahemoglobin.
Clinical application of pulse oximeters: SpO2 is an important physiological parameter
to reflect the respiration and ventilation function, so SpO2 monitoring used in clini-
cal becomes more popularly, such as monitoring the patient with serious respiratory
disease, the patient under anesthesia during operation, premature and neonate. The
status of SpO2 can be determined in time by measurement and find the hypoxemia
patient earlier, thereby preventing or reducing accidental death caused by hypoxia
effectively.
Disposal: The product must not be disposed of along with other domestic
waste. The users must dispose of this equipment by bringing it to a specific
recycling point for electric and electronic equipment.
