Abstract: The present application discloses an adaptive finger size ring. The adaptive finger size ring in the present application includes: a first ring body, a second ring body, and two elastic devices. There is a clamping position between the first ring body and the second ring body, and the clamping position is used to clamp a finger. One end of the elastic device is connected to the first ring body, the other end is connected to the second ring body, and the two elastic devices are respectively located on two sides of the clamping position. The elastic device, the first ring body, and the second ring body form an annular shape. The elastic device is telescopic and has a tendency to shorten in length, so that the first ring body and the second ring body are in close contact with skin of the finger. Thus, a swelling feeling caused due to poor blood flow when the ring is worn for a long time can be avoided, and wearing comfort is improved.

A measurement unit (2) is arranged inside the rigid ring body (1), and an elastic device (3), a photodiode (4), and at least one light emitting diode (5) are protrudingly disposed on an inner circumferential surface of the rigid ring body (1). When the ring-type pulse oximeter is worn, the elastic device (3) is pressed, so that the photodiode (4) and the at least one light emitting diode (5) fit with a finger, light emitted by the light emitting diode (5) is attenuated by the finger, then received by the photodiode (4) and processed by the measurement unit (2) to calculate blood oxygen saturation. The ring-type pulse oximeter exerts a force on a portion of the finger, such that the finger maintains a tight fit to the photodiode (4) and the light-emitting diode (5), thereby providing a comfortable wearing experience as well as adaptability to different finger shapes, and improving measurement accuracy.
