HANDHELD MULTI-PARAMETER MEASURING INSTRUMENT INTEGRATED WITH BLOOD OXYGEN SENSOR

摘要

Provided is a handheld multi-parameter measuring instrument (10) integrated with a blood oxygen sensor, comprising: a shell (100), having an accommodating cavity (140), a side wall (110), a first surface (120) and a second surface (130), wherein the first surface and the second surface are opposite each other; a cover plate (200) attached on the side wall (110) of the shell (100) and rotationally connected to the shell (100); a blood oxygen sensor (310), wherein the blood oxygen sensor (310) comprises a light emitting unit (312) and a light receiving unit (314), wherein the light emitting unit (312) is used for alternately emitting red light and infrared light and the light receiving unit (314) is used for receiving the red light and infrared light emitted by the light emitting unit (312); and a signal processing unit (320) accommodated in the accommodating cavity (140) of the shell (100) and used for controlling the light emitting unit (312) to alternately emit red light and infrared light, and calculating the blood oxygen saturation according to a signal received by the light receiving unit (314); wherein the light emitting unit (312) is arranged on one side, attached to the shell (100), of the cover plate (200) and the light receiving unit (314) is arranged on the side wall (110). During the measurement of the blood oxygen saturation, the first surface (120) and the second surface (130) of the shell (100) are held by one hand, and one finger is inserted between the cover plate (200) and the shell (100). The handheld multi-parameter measuring instrument (10) is convenient to use and has a high measurement accuracy.
