Description

technical field [0001] The invention relates to medical equipment, in particular to a digital physiological and biochemical parameter measuring device and a measuring method. Background technique [0002] The biochemical parameters of human blood, such as blood oxygen saturation, hemoglobin concentration, carbon monoxide hemoglobin concentration, blood sugar concentration, blood lipids and cholesterol, etc. have important clinical value, and can be measured by analyzing the different intensity of light absorption signals of different wavelengths. The value of the physiological parameters of the human body, such as the pulse wave of the human body, reflects the physiological state in which the heart beats out to the peripheral circulation. Utilizing the pulsation of human arterial blood, the non-invasive measurement of physiological and biochemical parameters in vivo can be realized by using an optical detection method. At present, the most commonly used finger-clip blood ox...
