Carbon oxygen saturation detection device and method

Abstract

The invention relates to a carbon oxygen saturation detection device which comprises a detection unit, a conversion unit, a processor and a display screen. The detection unit comprises a detector anda plurality of light sources of different wavelengths, wherein the detector detects the light intensity signals of the light emitted by the receiving light source reflected by the arterial blood in the tissues and sends the light intensity signals to the conversion unit; the conversion unit processes the light intensity signals and sends the signals to the processor; the processor analyzes the electrical signals to obtain carbon oxygen saturation. The invention also relates to a carbon oxygen saturation detection method which comprises the steps that an LED light source sequentially emits light signals to the tissues, and a photoelectric detector receives the light intensity signals and sends the light intensity signals to an analog front end; the analog front end receives the light intensity signals, converts the light intensity signals into voltage signals, filters and amplifies the voltage signals, converts the voltage signals into discrete digital carbon-oxygen signals, and sends the discrete digital carbon-oxygen signals to a single chip microcomputer; the single chip microcomputer calculates the saturation of carbon and oxygen. The carbon oxygen saturation detection device realizes non-invasive and real-time monitoring of carbon and oxygen saturation in human arterial blood.

Description

technical field [0001] The invention relates to the technical field of carbon and oxygen monitoring, in particular to a carbon and oxygen saturation detection device and method. Background technique [0002] Carboxyhemoglobin is a derivative of hemoglobin in human blood, which is the product of the combination of carbon monoxide and hemoglobin. In terms of binding capacity, the binding capacity of carbon monoxide and hemoglobin is 200-300 times that of oxygen and hemoglobin. In terms of dissociation rate, the dissociation rate of carboxyhemoglobin is only 1 / 3600 of that of oxyhemoglobin. When the human body inhales a large amount of carbon monoxide, carbon monoxide replaces oxygen and combines with hemoglobin, causing the oxygen-carrying capacity of hemoglobin to drop sharply, resulting in insufficient oxygen content in the blood, resulting in carbon monoxide poisoning. The severity of carbon monoxide poisoning is directly proportional to the carbon oxygen saturation. The c...
