How to use?
Put the ring on before sleep. A sleep report will be generated automatically in the morning, revealing your sleep apnea risk, sleep efficiency, and stress level.
The Belun® Ring helps you discover the quality of your sleep — at home, comfortably, by simply putting on your ring before bedtime.
You will uncover the mysteries of:
- Risk of sleep apnea
- Sleep quality
The Belun® Ring equips its users with information that empowers them to change their daily habits — such as activities, exercise, alcohol intake, and medication — to improve their sleep health.
The Belun® Ring’s report also enables professionals to evaluate how users’ daytime activities affect sleep quality and to review sleep health holistically and scientifically in an unprecedented way in the marketplace.
All physiological data, analysis, and sleep reports can be viewed and downloaded by people from clinics, health-check centers, respiratory machine vendors, and elderly centers, which provides additional insights to physicians.
Using the spectrophotometric methodology, the Belun® Ring measures blood oxygen saturation by illuminating the skin and measuring changes in light absorption of oxygenated (oxyhemoglobin) and deoxygenated (reduced hemoglobin) blood using two light wavelengths: red and infrared. The ratio of absorbance at these wavelengths is calculated and calibrated against direct measurements of arterial oxygen saturation (SaO2) to establish the pulse oximeter’s measurement of functional oxygen saturation of arterial hemoglobin (SpO2).
- The sensor should be placed on the palmar side of the proximal phalanx of the index finger and along the radial artery. The accuracy of the device will be minimally affected by the skin color.
- Worn at the proximal phalanx of the index finger & minimises sensor motion artifact
- Small, lightweight (13 gram) and cableless design
- Non-intrusive measurement at night
- Multiple-night home sleep test
