Fingertip Pulse Oximeter

This Fingertip Pulse Oximeter is a kind of innovated medical device with non- invasive features for artery SPO2 and PR detection. Being portable, it is able to measure SPO2 and PR values quickly and precisely.

General Description

Haemoglobin Saturation is the percentage between the capacity of Oxyhemoglobin (HbO2) that compounded with oxygen and that of all combinativable haemoglobin (Hb) in blood. In other words, it is the saturation of Oxyhemoglobin in blood. It is a very important physiological parameter for Respiratory and Circulation Systems. Many respiratory diseases could reduce haemoglobin saturation in human blood. Moreover, factors such as Automatic Organic Regulation Malfunction caused by anaesthesia, trauma resulted from major operation and some medical examination can also cause problems in oxygen supply, which might reduce human haemoglobin saturation. As a result, such symptoms as megrim, vomiting and asthenia might appear to patients. Hence, it is very important to know hemoglobin saturation of patient timely in clinical medical aspects. The fingertip pulse oximeter features in small volume, low power consumption, convenient operation and portability. It is only necessary for patient to put one finger into fingertip photoelectric sensor for diagnosis, and the display screen will directly show measured value of hemoglobin saturation. It has been proved in clinical experiments that it possesses rather high precision and repeatability.

Measurement principle

The principle of the oximeter is as follows: An experience formula of data process is established by exerting Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive hemoglobinand oxyhemoglobin (HbO2) in glow and near-infrared zones. Operation principle of the instrument is to combine Photoelectric Oxyhemoglobin Inspection Technology wth Cpacity Pulse Scanning and Recording Technology, so that two lights with different wavelength (660nm glow and 940nm near infrared light) can be focused onto human nail 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 Fingertip Pulse Oximeter together with MRI or CT equipment.
2. Explosion hazard: Do not use the Fingertip Pulse Oximeter in an explosive atmosphere.
3. The Fingertip Pulse Oximeter is intended only as an adjunct in patient assessment. Doctors should make diagnosis in conjunction with clinical manifestation and symptoms.
4. Check the Fingertip Pulse Oximeter sensor application site frequently to make sure that the circulation and skin integrality of patient are under good condition.
5. Do not stretch the adhesive tape while applying the Fingertip Pulse Oximeter sensor. This may cause inaccurate reading or skin blisters.
6. Please read the manual carefully before your operation.
7. The Fingertip Pulse Oximeter has no SpO2 prompt, it is not for continuous monitoring.
8. When used for a long time, it will produce discomfort or tenderness,especially for patients with microcirculation disorders.Please change the test sites periodically according to different situations of patients.The test site must be changed and the skin integrity and circulation condition of the patient must be checked at least every 2 hours, and the correct adjustment must be made.
9. Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or immersing the sensors in liquid.
10. Significant levels of dysfunctional hemoglobins (such as carboxyl-hemoglobin or methemoglobin) may cause inaccurate reading.
11. Intravascular dyes such as indocyanine green or methylene blue may cause inaccurate
12. SpO2 measurements may be adversely affected in the presence of high ambient light. Please shield the sensor area (with a surgical towel or direct sunlight, for example) if it is necessary.
13. Unexpected action may cause inaccurate reading.
14. Medical signal with high frequency or interference caused by defibrillator may lead to inaccurate reading.
15. Venous pulsations may cause inaccurate reading.
16. It may cause inaccurate reading when the positions of sensor and blood pressure cuff are on the same arterial catheter or intravascular line.
17. Hypotension, severe vasoconstriction, severe anemia, or hypothermia may cause inaccurate reading.
18. It may cause inaccurate reading by giving use of cardiotonic to patient after his cardiac arrest or when he is in quiver.
19. Bright nail or painted nail may cause inaccurate SpO2 reading. Follow local ordinances and recycling instructions regarding to disposal or recycling of the device and device components, including batteries
