Title:
BLOOD OXYGEN PARAMETER MEASUREMENT MODULE AND ELECTRONIC DEVICE WITH SAME
Document Type and Number:
WIPO Patent Application WO/2021/232375
Kind Code:
A1
Abstract:
A blood oxygen parameter measurement module, comprising an optical signal emission module (300) and a blood oxygen parameter measurement apparatus. The optical signal emission module (300) comprises two optical signal emission sub-modules (301, 302); and the blood oxygen parameter measurement apparatus comprises an optical signal filtering module (320), a photoelectric conversion module (310) and a signal processing module (330), wherein the optical signal filtering module (320) comprises a plurality of filtering areas, with different filtering areas being arranged in an intersecting manner; the photoelectric conversion module (310) comprises a plurality of photoelectric conversion areas, and the photoelectric conversion module (310) is located below the optical signal filtering module (320); and the signal processing module (330) is located inside the apparatus. When the optical signal emission module (300) simultaneously emits two different optical signals, the different optical signals are transmitted and reflected in the organism tissue of a user, and are then converted into corresponding electrical signals after being subjected to filtering and photoelectric conversion successively, and blood oxygen parameter information of the user is obtained according to the electrical signals. The two optical signal emission sub-modules (301, 302) are distributed on two sides of the central axis of the optical signal filtering module (320). The module can improve the precision of blood oxygen parameter measurement.
