Fingertip Pulse Oximeter
Model: oSport
This Fingertip Pulse Oximeter is a kind of innovated medical device with non-invasive and
continuous features for arterial SpO
2
and PR detection. Being portable, it is able to measure
SpO
2
and PR values quickly and precisely.
General Description
Hemoglobin Saturation is the percentage between the capacity of Oxyhemoglobin (HbO
2
) that
combines with oxygen and that of all combinative hemoglobin (Hb) in blood. In other words, it
is the saturation of Oxyhemoglobin in blood. Hemoglobin Saturation is a very important
physiological parameter for Respiratory and Circulation Systems. Many respiratory diseases
could reduce hemoglobin saturation in human blood. Moreover, factors such as Automatic
Organic Regulation Malfunction caused by anesthesia, trauma from a major operation and
some medical examinations that can also cause problems in oxygen supply, which might
reduce human hemoglobin saturation. As a result, such symptoms as megrim, vomiting and
asthenia might appear to patients. Hence, it is very important to have a timely knowledge of the
hemoglobin saturation of patients in clinical medical aspects.
The Fingertip pulse oximeter features in a small volume, low power consumption, convenient
operation and portability. It is only necessary for a patient to put a finger into the fingertip
photoelectric sensor for diagnosis, and the display screen will directly show the measured
value of hemoglobin saturation. It has been proved in clinical experiments that the fingertip
pulse oximeter possesses a high precision and repeatability.
Measurement principle
The principle of the oximeter is as follows: An experience formula of data process is
established by exerting the Beer-Lambert Law according to Spectrum Absorption
Characteristics of Reductive hemoglobin(R Hb) and oxyhemoglobin (O
2
Hb) in glow and
near-infrared zones. The operation principle of the instrument is to combine Photoelectric
Oxyhemoglobin Inspection Technology with Capacity Pulse Scanning and Recording
Technology, so that two lights with different wavelengths (660nm glow and 940nm near
infrared light) can be focused onto human nail through a perspective clamp finger-type sensor.
The measured signal can be obtained by a photosensitive element and the information
acquired will be shown on two groups of LEDs through process in electronic circuits and
microprocessor.

Precautions for use
1.
Do not use the pulse oximeter together with MRI or CT equipment.
2.
Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.
3.
The pulse oximeter is intended only as an adjunct in patient assessment; Doctors should
make a diagnosis in conjunction with clinical manifestation and symptoms.
4.
Check the pulse oximeter sensor application site frequently to make sure that the
circulation and skin integrality of patient are in good condition.
5.
Do not stretch the adhesive tape while applying the pulse oximeter sensor. This may
cause inaccurate readings and skin blisters.
6.
Please read the manual carefully before your operation.
7.
The pulse oximeter has no SPO
2
prompt, it is not for continuous monitoring.
8.
Prolonged use or the patient’s condition may require changing the sensor site periodically.
Change sensor site and check skin integrality, circulatory status, and correct alignment at
least every 2 hours.
9.
Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or
immersing the sensors in liquid.
10. Significant levels of dysfunctional hemoglobin (such as carboxyl- hemoglobin or
methemoglobin) may cause an inaccurate reading.
11. Intravascular dyes such as indocyanine green or methylene blue may cause an
inaccurate reading.
12. SpO
2
measurements may be adversely affected in the presence of high ambient light.
Please shield the sensor area (with a surgical towel or direct sunlight, for example) if it is
necessary.
13. Unexpected actions may cause inaccurate reading.
14. A medical signal with high frequency or interference caused by defibrillator may lead to
an inaccurate reading.
15. Venous pulsations may cause inaccurate readings.
16. There could be an inaccurate reading when the positions of sensor and blood pressure
cuff are on the same arterial catheter or intravascular line.
17. Hypotension, severe vasoconstriction, severe anemia, or hypothermia may cause
inaccurate readings.
18. An inaccurate reading may be caused by use of cardiotonic in a patient after his cardiac
arrest or when he is in a quiver.
19. Bright nail or painted nail may cause inaccurate SpO
2
reading.
Follow local ordinances and recycling instructions regarding the disposal or the recycling of the
device and device components.
Scope of application / intended use
The fingertip pulse oximeter can be used to detect blood oxygen saturation and pulse rate in
hospitals, families, schools and medical centers.

Operation Instructions
1. Install a pair of AAA batteries into battery compartment.
2. Plug a finger into rubber hole of the Oximeter.
3. Press button on the front panel to start.
4. Do not shake your finger or move your body when the Oximeter is working.
5. Press the button if you want change display direction.
6. Read relevant value from display screen.
7. The device will automatically power off in 8 seconds if there is no finger signal.
8. Please charge the batteries when the batteries run out of power.
When plugging your finger into the Oximeter, your nail surface must be upward.
Declaration: Please use the medical alcohol to clean the rubber before each test and clean the
tested finger with alcohol before and after the test. (The rubber inside of the Oximeter is a
medical rubber, which has no toxin, causes no harm, and brings no side effect such as allergy
to the skin ).
