Blood-culture carbon dioxide trace-gas detection system and detection method thereof

Abstract

The invention relates to a blood-culture carbon dioxide trace-gas detection system and a detection method thereof. The blood-culture carbon dioxide trace-gas detection system is characterized by comprising a detection device and an image collection device, wherein the detection device comprises a reaction bottle, the opening of the reaction bottle is provided with a seal cover, the seal cover is provided with a capillary glass tube insertion hole, one end of a capillary glass tube is inserted into the reaction bottle through the capillary glass tube insertion hole, and color liquid is contained in the capillary glass tube and forms a liquid column in the capillary glass tube; the image collection device aims at photographing the color liquid in the capillary glass tube, and a picture taken by the image collection device is transmitted to a computer to be processed. The blood-culture carbon dioxide trace-gas detection system has the beneficial effects that the micro increment of gas is changed to the obvious displacement of liquid, so that observation and measurement are easy; the stationary image collection device is used for taking picture, and after the picture is subjected to computer image processing, the distance is measured, so that the movement distance of the liquid column before and after the reaction can be measured; moreover, the blood-culture carbon dioxide trace-gas detection system is simple in structure, convenient to operate, low in cost, high in precision and wide in application range.

Description

technical field [0001] The invention relates to a trace gas detection system and method, in particular to a blood culture carbon dioxide trace gas detection system and a detection method thereof. Background technique [0002] Trace gases are produced in many biochemical and medical experiments. In the method of measuring reactants, the reaction products are usually converted into chromogenic substances, which are detected by spectrophotometry, and the traces generated during the reaction are rarely considered. Gases are detected directly. Based on the direct detection of trace gas volume, it is hoped to find a simple and new method for the quantitative detection of reactants. [0003] Sepsis refers to the acute systemic infection caused by pathogenic bacteria or opportunistic pathogenic bacteria invading the blood circulation, growing and multiplying in the blood, and producing toxins. Clinically, sepsis is a critical stage of infectious diseases, how to quickly and accura...
