Fingertip Pulse Oximeter
General Description
Haemoglobin Saturation is percentage of Oxyhemoglobin (HbO2) capacity, compounded with
oxygen, by all combinativable haemoglobin (Hb) obin (HbO2) capacity in blood. In other
words, it is consistence of Oxyhemoglobin in blood. It is a very important ecological
parameter for Respiratory circulation System. Many respiratory diseases can result in
haemoglobin Saturation being lowered in human blood. Moreover, the following factors can
also lead to problems in oxygen supply, so that human haemoglobin saturation might be
reduced: Automatic Organic Regulation Malfunction caused by Anesthesia, Intensive
Postoperative Trauma, hurts resulted in by some medical examination and etc. In the
situation, illnesses, such as light head, asthenia, vomitory and etc, might happen to patients
and even endanger the patient's life. Therefore, it is very important to know Hemoglobin
saturation of patient timely in clinical medical aspects. So that doctors can find problems in
time.
The fingertip pulse oximeter features in small volume, low power consumption, convenient
operation and being portable. It is only necessary for patient to put one of his fingers into a
fingertip photoelectric sensor for diagnosis, and a display screen will directly show measured
value of hemoglobin Saturation. It has been proved in clinical experiments that it features in
rather high precise and repeatability.
Measurement 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(R Hb) and Oxyhemoglobin (O2 Hb) in glow and near-infrared zones.
Operation principle of the instrument is Photoelectric Oxyhemoglobin Inspection Technology
is adopted in accordance with Capacity Pulse Scanning and Recording Technology, so that
two beams of different wavelength of lights (660nm glow and 940nm near infrared light) 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 two groups of LEDs through process in electronic circuits and microprocessor.

Precautions for use
1 Do not use the pulse oximeter in an MRI or CT environment
2 Do not use the pulse oximeter in situations where alarms are required. The device has
no alarms.
3 Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.
4 The pulse oximeter is intended only as an adjunct in patient assessment. It must be
used in conjunction with other methods of assessing clinical signs and symptoms.
5 Check the pulse oximeter sensor application site frequently to determine the positioning
of the sensor and circulation and skin sensitivity of the patient.
6 Do not stretch the adhesive tape while applying the pulse oximeter sensor. This may
cause inaccurate readings or skin blisters.
7 Before use, carefully read the manual.
8 The pulse oximeter has no SpO2 alarms; it is not for continuous monitoring, as indicated
by the symbol.
Prolonged use or the patient's condition may require changing the sensor site
9
periodically. Change sensor site and check skin integrity, circulatory status, and correct
alignment at least every 4 hours.
10 Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or
immersing the sensors in liquid may cause inaccurate readings.
11 Significant levels of dysfunctional hemoglobins (such as carbonxy- hemoglobin or
methemoglobin)
12 Intravascular dyes such as indocyanine green or methylene blue
13 SpO2 measurements may be adversely affected in the presence of high ambient light.
Shield the sensor area (with a surgical towel, or direct sunlight, for example) if
necessary.
14 Excessive patient movement
15 Venous pulsations
16 Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line
17 The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
18 The patient is in cardiac arrest or is in shock.
19 Fingernail polish or false fingernails may cause inaccurate SpO2 readings.
Follow local ordinances and recycling instructions regarding disposal or recycling of
the device and device components, including batteries.
Product Properties
1 Operation of the product is simple and convenient.
2 The product is small in volume, light in weight (total weight is about 50g including
batteries) and convenient in carrying.
3 Power consumption of the product is low and the two originally-equipped two AAA
batteries can be operated continuously for 30 hours.
4 Low voltage warning will be indicated in visual window when battery voltage is so low
that normal operation of the oximeter might be influenced.
5 The oximeter will power on automatically once you introduce your finger
6 The product will automatically be powered off when no signal is in the product for longer
than 8 seconds.
Product Operation Scope
The fingertip Oximeter can be used to measure human Haemoglobin Saturation and heart
rate through finger. The product is suitable for use in family, hospital (including clinical use in
internist/surgery, Anaesthesia, paediatrics, intensive care and etc.) Oxygen Club, social
medical organizations, physical care in sports (It can be used before or after sports.
Operation in sport procedure is not recommended) and etc.
The product is not suitable to monitor patient continuously.
Operation Instructions
1 Installing two AAA batteries into battery cassette before covering its cover.
2 Nip the clamp as diagram
3 Plug one of fingers into rubber hole of the Oximeter (it is best to plug the finger
thoroughly) before releasing the clamp
4 Press the switch button once on front panel.
5 Your finger do not tremble during the Oximeter is working. Your body is not
recommended in moving status
6 Read correspondent datum from display screen.
Six display modes

Declaration: Please use the medical alcohol to clean the rubber touching the finger inside of
Oximeter, and clean the test finger using alcohol before and after each test. (The rubber
inside of the Oximeter belongs medical rubber, which has no toxin, and no harmful to the skin
of human being).
When your finger is plugged into the Oximeter, your nail surface must be upward.
