Abstract: A device and method for detecting a sign parameter are provided. A luminous source (01) is utilized to irradiate human skin tissue(s) for a preset time. The luminous source (01) can emit light with set wavelength(s) and capable of being absorbed by substance(s) for characterizing human body sign(s) in a human body. A photoelectric sensor (02) is configured to detect absorbance of the human body to the light emitted by the luminous source (01) within the preset time, and send a detection result to a processor (03). The processor (03) is configured to calculate substance concentration(s) of the substance(s) for characterizing the human body sign(s) in the human body according to the detection result sent by the photoelectric sensor (02). Therefore, blood samples of subjects do not need to be collected, and the substances for characterizing the human body signs can be detected through a non-invasive method.
