different individual pulse rate.
If some abnormal conditions appear on the screen during test process, pull out the
finger and reinsert to restore normal use.
The device has normal useful life for three years since the first electrified use.
The hanging rope attached the product is made from Non- allergy material,
if particular group are sensitive to the hanging rope, stop using it. In addition,
pay attention to the use of the hanging rope , do not wear it around the neck
avoiding cause harm to the patient.
OXY-2 FINGER OXIMETER
User manual
ATTENTION:
The operators must carefully read
and completely understand the present manual
before using the product.
The instrument dose not have low-voltage alarm function, it only shows the
low-voltage, please change the battery when the battery energy is used out.
When the parameter is particularly, The instrument dose not have alarm function.
Do not use the device in situations where alarms are required.
Batteries must be removed if the device is going to be stored for more than one
month, or else batteries may leak.
A flexible circuit connects the two parts of the device. Do not twist or pull on the
connection.
1.4 Indication for Use
The Fingertip Pulse Oximeter is a non-invasive device intended for the spot-check
of oxygen saturation of arterial hemoglobin (SpO
2
) and the pulse rate of adult and
pediatric patients in home and hospital environments (including clinical use in internist/
surgery, anesthesia, intensive care ect.). This device is not intended for continuous
monitoring.
2 Overview
The pulse oxygen saturation is the percentage of HbO
2
in the total Hb in the blood,
so-called the O2 concentration in the blood. It is an important bio-parameter for the
respiration. For the purpose of measuring the SpO
2
more easily and accurately, our
company developed the Pulse Oximeter.
At the same time, the device can measure the pulse rate simultaneously.
The 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.
2.1 Features
• Operation of the product is simple and convenient.
• The product is small in volume, light in weight (total weight is about 50g including
batteries) and convenient in carrying.
• Power consumption of the product is low and the two originally equipped AAA
batteries can be operated continuously for 24 hours.
• The product will automatically be powered off when no signal is in the product within
5 seconds.
• Low-battery indicator as battery icon flash manner.
2.2 Major Applications and Scope of Application
The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse
rate through finger, and indicate the pulse intensity by the bar-display. The product is
suitable for use in family, hospital (Ordinary sickroom ), Oxygen Bar, social medical
organizations and also the measure of saturation oxygen and pulse rate.
The product is not suitable for use in continuous supervision for patients.
The problem of overrating would emerge when the patient is suffering
from toxicosis which caused by carbon monoxide, the device is not
recommended to be used under this circumstance.
2.3 Environment Requirements
Storage Environment
a) Temperature: -40°C~+60°C
b) Relative humidity: ≤95%
c) Atmospheric pressure: 500hPa~1060hPa
Operating Environment
a) Temperature: 10°C~40°C
b) Relative Humidity: ≤75%
c) Atmospheric pressure: 700hPa~1060hPa
3 Principle and Caution
3.1 Principle of Measurement
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 (Hb) and Oxyhemoglobin (HbO
2
) in glow
& near-infrared zones. Operation principle of the instrument is: Photoelectric
Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse
Scanning & Recording Technology, so that two beams of different wavelength of lights
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 screen through treatment in electronic circuits
and microprocessor.
Figure 1. Operating Principle
3.2 Caution
1. The finger should be placed properly (see the attached illustration of this manual,
Figure 5), or else it may cause inaccurate measurement.
2. The SpO
2
sensor and photoelectric receiving tube should be arranged in a way with
the subject’s arteriole in a position there between.
3. The SpO
2
sensor should not be used at a location or limb tied with arterial canal or
blood pressure cuff or receiving intravenous injection.
4. Make sure the optical path is free from any optical obstacles like rubberized fabric.
5. Excessive ambient light may affect the measuring result. It includes fluorescent lamp,
dual ruby light, infrared heater, direct sunlight and etc.
6. Strenuous action of the subject or extreme electrosurgical interference may also
affect the accuracy.
7. Testee can not use enamel or other makeup.
3.3 Clinical Restrictions
1. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood
flow of subject is required. For a subject with weak pulse due to shock, low ambient/
body temperature, major bleeding, or use of vascular contracting drug, the SpO
2
waveform (PLETH) will decrease. In this case, the measurement will be more
sensitive to interference.
2. For those with a substantial amount of staining dilution drug (such as methylene
blue, indigo green and acid indigo blue), or carbon monoxide hemoglobin (COHb),
or methionine (Me+Hb) or thiosalicylic hemoglobin, and some with icterus problem,
the SpO
2
determination by this monitor may be inaccurate.
3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be
a major factor blamed for serious error of SpO
2
measure.
4. As the SpO
2
value serves as a reference value for judgement of anemic anoxia
and toxic anoxia, some patients with serious anemia may also report good SpO
2
measurement.
