Fingertip Pulse Oximeter
This Fingertip Pulse Oximeter is a kind of innovated medical device with non-invasive and continuous 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 combined haemoglobin (Hb) obin (HbO2) 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 hemoglobin(R Hb) and oxyhemoglobin (O2 Hb) in glow and near-infrared zones. Operation principle of the instrument is to combine Photoelectric Oxyhemoglobin Inspection Technology with Capacity 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, and then measurement signal got via a photosensitive element. Relevant measurement information will be processed in electronic circuits and microprocessor and then showed up on the OLED display.

1. Do not use the pulse oximeter together with MRI or CT equipment.
2. Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.
3. The 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 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 pulse oximeter sensor. This may cause inaccurate reading or skin blisters.
6. Please read the manual carefully before your operation.
7. The pulse oximeter has blood oxygen saturation prompt function, but it is not for continuously monitoring.
8. Prolonged use or the patient’s condition may require changing the sensor site periodically, change sensor site and check skin integrality, circulatory status, and correct alignment at least every 2 hours.
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 reading.
12. SpO2 measurements may be adversely affected in the presence of high ambient light. Please use surgical towel against direct sunlight to protect the oximeter 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.
