Intex Oxicare User manual

The finger pulse oximeter produced by our company is a
kind of noninvasive and continuous medical instrument for
detecting the arterial oxygen saturation and pulse rate of
human body. It is portable and can accurately and rapidly
measure the blood oxygen, so that you know whether you
are lack of oxygen at present.
USER MANUAL

Blood oxygen saturation is the percentage of the capacity of
HBO2 in the blood which is combined with oxygen in the total
capacity of Hb. That is, the concentration of blood oxygen,
which isavery important physiological parameter of the
respiratory and circulatory system. Many respiratory
diseases can cause the decrease of oxygen saturation. In
addition, the dysfunction of the body's automatic regulation
caused by anesthesia, surgical trauma and some injuries
caused by medical examination may lead to the patient's
oxygen supply problems and reduce the human oxygen
saturation, resulting in some adverse reactions such as
vertigo, vomiting, weakness and other symptoms. If the
treatment measures are not taken in time, the patients' lives
will be endangered. Therefore, it is very important for doctors
to find out the problem in time by knowing the patient's
oxygen saturation in time.
◆The finger clip type pulse oximeter (hereinafter referred to
as the oximeter) has the advantages of small volume, low
power consumption, simple operation and convenient
carrying. When measuring, as long as the finger is extended
into the finger clamp photoelectric sensor, the display screen
will directly display the measured blood oxygen saturation
value.
◆The measurement principle of the oximeter is based on the
spectral characteristics of hemoglobin and oxyhemoglobin
with different absorption rates in the red and infrared light
areas, and the empirical formula of data is established by
using "lamert beer" law. The working principle of the
instrument is to use photoelectric blood oxygen detection
technology combined with volume pulse tracing technology.
Two different wavelengths of light (660nm red light and
940nm near-infrared light) are used to irradiate the fingernail
of human body through absorption perspective clip sensor,
and the measurement signal is obtained by the photosensi-
tive element. The obtained information is displayed on the
◆Measurement principle
Summary

display after the electronic circuit and microprocessor, which
is easy to read.
◆It is composed of double-layer components and
photoelectric detector. Bone, cell tissue, pigmentation and
vein vessels all have different absorption constants of light.
When the artery pulsates with the heart's contraction and
relaxation, the absorption of light will be different with the
increase and decrease of blood flow. The absorptivity of
different light during diastole and contraction of the heart is
transformed into the measurement result of blood oxygen
saturation. This measurement is the oxygen saturation.
1. It can not be used together with MRI or CT equipment.
2. Explosion hazard: do not use this instrument in the
environment of flammable anesthetic gas.
3. The oximeter only plays an auxiliary role in the diagnosis
of the patient. Please ask the doctor to makeadiagnosis
based on the clinical manifestations and symptoms.
4. Always check the sensor test point of the oximeter to
confirm that the patient's skin at the sensor test point is
complete and in good circulation.
5. The sensor of the finger clip pulse oximeter is not suitable
to contact the adhesive tape, which may cause the
measurement data error or mistakenly think that the tested
skin has blisters.
6. Please read this manual carefully before use.

7. The oximeter does not have the function of blood oxygen
prompt, but it can not be used as a long-term continuous
monitor.
8. When using for a long time, please change the test point
periodically according to the different situation of the patient.
The test point must be replaced every2hours at most and
the skin integrity, circulation and correct adjustment of the
patient must be checked.
9. High pressure disinfection, vinyl oxide disinfectant or
immersion of the sensor in the liquid disinfectant will cause
incorrect readings.
10. Dysfunction of important indicators of hemoglobin (such
as carbohemoglobin or methemoglobin) can cause incorrect
readings.
11. Excessive staining in blood vessels, such as indocyanine
green or methylene blue, may cause incorrect readings.
12. The measurement accuracy of blood oxygen saturation
will be affected by the strong light of the surrounding
environment. (e.g. wipes or direct sunlight) add a protective
enclosure to the sensor if necessary.
13. The patient's unexpected movements may cause
incorrect readings.
14. The interference of medical high frequency signal or
defibrillator may cause wrong reading.
15. Rhythmic pulsation of the vein can cause incorrect
readings.
16. The measurement position of the sensor and the blood
pressure cuff are in the same artery or the same blood
vessel, which may cause wrong readings.
17. Patients with hypotension, severe systolic hypotension,
severe anemia or hypothermia may cause incorrect readings
18. If the patient uses a cardiotonic after the heart stops
beating, or if the patient shivers, it will cause a wrong reading
19.bright nails or nail polish coated nails cause erroneous
readings.
