Fingertip Pulse Oximeter
General Description
Hemoglobin saturation
is a measurement of the number of oxygen molecules bound by each
molecule of hemoglobin
expressed as a percentage. It is a very important physiological
parameter for the respiratory/circulatory system. Many respiratory diseases can result in
hemoglobin saturation being lowered in human blood. Moreover, the following factors can
also lead to problems in oxygen supply, so that human hemoglobin saturation might be
reduced: Automatic Organic Regulation Malfunction caused by Anesthesia, Postoperative
Trauma, injury caused by some medical examinations, illnesses etc. and may endanger the
patient’s life. Therefore, it is very important to know the Hemoglobin saturation of the patient
so that problems can be identified and rectified in a timely manner.
The Fingertip Pulse Oximeter is a small device with a low power consumption, simple to
operate and extremely portable. It is only necessary
to apply the device to the patient’s finger
for the fingertip photoelectric sensor to measure and display the measured value of
hemoglobin saturation on the OLED screen. It has been proven in clinical experiments that it
is a precise and repeatable me
thod of obtaining the patient’s hemoglobin saturation.
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.
The operating principle of the instrument is Photoelectric Oxyhemoglobin Inspection
Technology which 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 the human nail tip through clamp-type finger sensor. Then
the measured signal can be obtained by a photosensitive element, information acquired
through which will be shown on two groups of LEDs on the display.

Precautions for use
1
Before use, carefully read the manual.
2
Do not use the pulse oximeter in an MRI or CT environment
3
Do not use the pulse oximeter in situations where alarms are required. The device has
no alarms.
4
Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.
5
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.
6
Check the pulse oximeter sensor application site
frequently
to determine the positioning
of the sensor and circulation and skin sensitivity of the patient.
7
Do not use adhesive tape to secure the pulse oximeter sensor to the patient. This may
cause inaccurate readings or skin blisters.
8
The pulse oximeter has no SpO2 alarms. It is not for continuous monitoring as indicated
by the symbol
9
Prolonged use,
or the patient’s condition, may require changing the sensor site
periodically. Change sensor site and check skin integrity, circulatory status, and correct
alignment at least every 4 hours.
10
Do not autoclave, ethylene oxide sterilize, or immersing the sensors in liquids.
The following may cause inaccurate readings:
Significant levels of dysfunctional hemoglobins (such as carbonxy- hemoglobin or
methemoglobin)..
Intravascular dyes such as indocyanine green or methylene blue.
SpO2 measurements may be adversely affected in the presence of high ambient light or
direct sunlight (shield the sensor area and, if necessary cover the sensor).
Excessive patient movement or venous pulsations.
Placement of the sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line.
If the patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
If the patient is in cardiac arrest or is in shock
Fingernail polish or false fingernails may cause inaccurate SpO2 readings.
Product Properties
1
Operation of the product is simple and convenient
2
The product is small, lightweight (total weight is about 50g including batteries) and
convenient to carry.
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 product will automatically be powered off when no signal is detected by the product
for longer than 8 seconds.
Product Operation Scope
The fingertip Oximeter can be used to measure Hemoglobin Saturation and heart rate
through the finger tip. The product is suitable for use in the home, in the field and in hospital
(including clinical use in internist/surgery, Anesthesia, pediatrics, intensive care and etc.) and
anywhere the measurement of hemoglobin saturation is required.
The product is not suitable to monitor the patient continuously.
Operation Instructions
1
Install the two AAA batteries into battery compartment and replace the cover.
2
Grip the clamp as shown below
3
Insert the patient’s finger fully into the Oximeter and release the clamp.
4
Press the ON button on front panel once.
5
Read the data from display screen.
Note: When your finger is placed into the Oximeter, the nail surface must be facing upward.
Display Modes
The Oximeter has six (6) display modes. After the Oximeter is turned ON, each time you
press the power switch, the oximeter will switch to another display mode as follows:
1.
2.
3.
4.
5.
6.
When you press the power switch for more than one second, the brightness of the oximeter
will be changed by degrees, there are 10 levels of brightness; the default level is level four.
Note: Please use medical grade alcohol to clean the rubber inside of the Oximeter between
patients and clean the test finger using alcohol before and after each test. (The rubber used is
of a medical grade and has no toxins and is not harmful to the skin).
