Fingertip Pulse Oximeter
General Description
The measurement of oxygen saturation of arterial blood (also known
as pulse oxygen saturation, usually shortened as SpO2) adopts the
principles of light spectra and volume tracing. The LED emits lights with
two specific wavelengths, which are selectively absorbed by oxygenated
hemoglobin and deoxyhemoglobin. The optical receptor measures the
changes in the light intensity after the light passes the capillary network
and estimates the ratio of oxygenated hemoglobin and the total
hemoglobin.
Precautions for use
◼Explosion hazard. Do not use the oximeter in the presence of
flammable anesthetics mixture with air, oxygen, or hydrogen.
◼When the oximeter is in use, there should not be any great power
appliances as high voltage cables, X-ray machine, ultrasound
equipment and electrizer in use nearby.
◼Keep the oximeter away from dust, vibration, corrosive substances,
explosive materials, high temperature and moisture.
◼This oximeter for sports or aviation use only.
◼The oximeter should be handled with care so as to avoid shocks and
falls.
◼When the oximeter is in use, it must be ensured the batteries have
sufficient capacity; otherwise there might be such phenomena as
starting-up abnormalities or inaccurate measurement data, etc.
◼Please do not use such pointed objects as pen point or nails for
pressing operation, otherwise it might cause permanent damage to the
surface of the keyboard.
◼To ensure accurate performance and prevent device failure, do not
expose the oximeter to extreme moisture, such as direct exposure to
rain. Such exposure may cause inaccurate performance or device
failure.
◼Do not conduct SpO2measurement on the finger smeared with nail
polish, otherwise this will lead to unreliable measurement results.
◼Please do not open the enclosure. The enclosure shall only be opened
by the authorized person.
◼In order to have more accurate measurements of SpO2and PR, the
oximeter should be used in quiet and comfortable environment.
◼Follow local ordinances and recycling instructions regarding disposal or
recycling of the device and device components, including batteries.
Intended Use
This product is intended for sports and aviation use only. It should not
be used to diagnose or treat any medical condition .
Operation Instructions
1. Install two AAA batteries into battery cassette before closing its
cover.
2. Nip the oximeter, then insert one of fingers
into the rubber hole of the oximeter before
releasing the oximeter, and your nail surface
must be upward.
3. Press the function button once on front panel.
4. Your finger and body do not tremble during measuring.
5. Read corresponding data in only one direction on the display
screen.

Battery Installations
1. Press the button down on the back panel of oximeter and push the
battery cover horizontally along the arrow shown as below:
2. Install the two AAA batteries into battery cabin
in correct polarities.
3. Close the battery cover.
Notes:
◼Pay attention to the correct polarities terminals of the battery,
which are marked with plus and minus signs. Do not install the
battery in the direction of the spring.
◼Please remove the battery if the oximeter will not be used for long
time.
Maintenance
1. Use a soft cloth dampened with either a commercial, nonabrasive
cleaner, or a solution of 70% alcohol in water, lightly wipe the surfaces
of the oximeter.
2. The most commonly used hospital cleaning agent and non-corrosive
detergents can be used for cleaning the oximeter, but please be careful
that many types of detergents must be diluted before use; Please use
them according to the directions of the manufacturers of the
detergents.
3. Avoid using alcohol-based, amido or acetone-based detergents
4. The casing of the oximeter should be kept from the contamination of
filth and dirt, and it can be wiped with non-velvet soft cloth. When
cleaning, do not spill the liquid onto the instrument. Ensure no liquid is
allowed to enter the inside of the oximeter.
5. It is forbidden to use such grinding materials as wire brush or metal
polishing agent, because these materials may cause damage to the
panels of the oximeter.
6. Please do not soak the oximeter in liquid.
7. Under normal circumstances, it is unnecessary for the oximeter to have
special maintenance, and cautions must be exercised on the following
points during the use of the oximeter:
◼Please use the oximeter in the environment according to the
requirements of the performance criteria.
◼Avoid contacts with organic solutions, dusts or corrosive gases.

◆Sensors specifications
Wavelength
Pulse oximetry sensors contain LEDs that emit
red light at a wavelength of approximately 660
nm and infrared light at a wavelength of
approximately 905 nm.
The total optical output power of the sensor
LEDs is less than 15 mW.
This information may be useful to clinicians,
such as those performing photodynamic
therapy.
Note: Sensor LED light emissions fall within
Class 1 level, according to IEC 60825-1:2001.
No special safety precautions are required.
