Do not immerge the oximeter in liquid. When it needs cleaning, please wipe its surface with medical alcohol
by soft material. Do not spray any liquid on the device directly.
When cleaning the device with water, the temperature should be lower than 60℃.
If fingers are too thin or too cold, this may affect the normal measure of the patients' SpO
2
and pulse rate,
please use a thicker finger such as the thumb and middle finger deeply enough into the probe.
Do not use the device on infant or neonatal patients.

110kg).
The device may not work for all patients. If you are unable to achieve stable readings, discontinue use.
The update period of data is less than 5 seconds, which is changeable according to 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 you are sensitive to the
hanging rope, stop using it. In addition, pay attention to the use of the hanging rope, do not wear around the
neck to avoid any harm.
The instrument does not have a low-voltage alarm function, it only shows the low-voltage. Please change
batteries when they run out.
The instrument does 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 etc.). 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 O
2
concentration
in the blood. It is an important bio-parameter for respiration. For the purpose of measuring the SpO
2
more easily
and accurately, Kinetik Wellbeing have developed this Pulse Oximeter. This device can also measure the pulse
rate simultaneously.
The Pulse Oximeter includes features such as; low power consumption, convenient operation, small and being
portable. It is only necessary for users to put one of their fingers into a fingertip photoelectric sensor for diagnosis,
and a display screen will directly show measured value of Hemoglobin Saturation.
2.1 Classification:
Class II b (MDD93/42/EEC IX Rule 10)
Class II (U.S.FDA)
2.2 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 power off when no signal is in the product within 5 seconds.
➢
Low‐battery indicator as battery icon flash manner.
2.3 Major Applications and Scope of Application
The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through the finger and
indicate the pulse intensity by the bar-display. The product is suitable for use in family, Oxygen bars, 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 if the patient is suffering from toxicosis caused by carbon
monoxide, the device is not recommended to be used under this circumstance.
2.4 Environment Requirements
Storage Environment
a) Temperature: -40℃~+60℃
b) Relative humidity:
≤
95%
c) Atmospheric pressure :500hPa~1060hPa
Operating Environment
a) Temperature: :10℃~40℃
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
correct position.
3.
The SpO
2
sensor should not be used at a location or limb that is 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 etc.
6.
Strenuous action of the subject or extreme electrosurgical interference may also affect the accuracy.
7.
Users cannot 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 cause serious error of SpO
2
measurement.
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.
