The Comprehensive Guide to SpO2 Finger Sensors in China
SpO2 finger sensors are crucial medical devices used for non-invasive blood oxygen saturation monitoring. They are widely used in hospitals, clinics, and even home healthcare settings in China. Understanding their different types and technical specifications is vital for healthcare professionals and suppliers alike. Companies like APK Technology (www.apk-technology.com), Unimed Medical (www.unimed.cn), and Shenzhen Best Electronics (www.Chinax.com) are prominent players in the Chinese market, offering a wide range of SpO2 sensors. Others such as UpnMed (upnmed.diytrade.com) and GM Medical (www.gmmedical.net) also contribute significantly to this market.
Understanding the Technology
SpO2 sensors utilize pulse oximetry, a technique developed in the 1970s. This method employs light-emitting diodes (LEDs) that transmit red and infrared light through the fingertip. A photodetector measures the amount of light absorbed by the blood. The difference in absorption between oxygenated and deoxygenated hemoglobin allows for the calculation of SpO2 levels. The resulting data is then displayed on a pulse oximeter or patient monitor. The accuracy and reliability of these readings are crucial for patient care.

FAQs
1. What is the difference between reusable and disposable SpO2 sensors?
Reusable sensors can be cleaned and sterilized for multiple uses, making them cost-effective. Disposable sensors are used once and then discarded, minimizing the risk of cross-contamination.
2. How accurate are SpO2 finger sensors?
Accuracy varies depending on the sensor and manufacturer. Generally, accuracy is within ±2% for SpO2 levels between 90-100% and ±3% for levels between 70-89%.
3. What are the common connector types for SpO2 sensors?
Common connector types include DB9 (9-pin), various proprietary connectors from different manufacturers (Masimo, Nellcor, etc.), and 6-pin connectors.
4. How long is the typical warranty for a reusable SpO2 sensor?
Warranties typically range from 6 to 12 months, depending on the manufacturer and specific product.
5. What factors should I consider when choosing a SpO2 sensor?
Consider compatibility with your monitor, the patient’s age and size, reusability needs, and the sensor’s accuracy and comfort level. Always prioritize patient safety and comfort.
