Blood bacterium culturing and detecting device and blood bacterium culturing detector

Abstract

The invention provides a blood bacterium culturing and detecting device and a blood bacterium culturing detector, and relates to the technical field of medical detection devices. The device comprises a laser, the detector, a blood culture bottle, a PLC and an alarm, the blood culture bottle is used for containing a medium and blood, the laser and the detector are respectively arranged at two sides of the blood culture bottle, the laser is used for emitting laser lights and irradiating the blood culture bottle, the detector is used for detecting the intensity of the laser lights traversing through the blood culture bottle, and the PLC controls the starting or not of the alarm according to the laser intensity detected by the detector. The problems of long detection time, high detection cost and environment pollution caused by use of a plurality of disposable culture bottles of existing non-invasive blood bacterium detection devices are solved, and the purposes of shortening of the detection cycle, reduction of error sources, increase of the detection efficiency and the detection accuracy, great reduction of the detection cost, and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of medical detection equipment, in particular to a blood bacteria culture detection device and a blood bacteria culture detector. Background technique [0002] Bacterial culture and detection of blood samples are necessary measures for the diagnosis of blood infection diseases. Sepsis and bacteremia caused by microorganisms invading the blood are clinically critical diseases. For patients with blood infectious diseases, whether they can be cured effectively depends to a large extent on rapid, timely and accurate test reports. [0003] At present, the methods of blood bacterial culture detection are divided into two types: invasive and non-invasive. Because invasive detection requires high professional skills of operators, heavy workload, long time consumption, and few sampling points, it is easy to cause interference of bacteria and affect the detection results. The efficiency and accuracy of the method hav...

Problems solved by technology

[0003] At present, the methods of blood bacterial culture detection are divided into two types: invasive and non-invasive. Because invasive detection requires high professional skills of operators, heavy workload, long time consumption, and few sampling points, it is easy to cause interference of bacteria and affect the detection results. The efficiency and accuracy of the method have limited its application; non-invasive detection mainly uses the metabolization of microorganisms in the blood to produce carbon dioxide as the basis for judging the presence or absence of microorganisms. Commonly used detection devices include homogeneous fluorescence enhanced detection devices, color detection Devices (carbon dioxide receptors) and radiolabel detection devices, etc. These detection devices use the interaction between carbon dioxide and fluorescent substances or water to mark, indirectly detect the presence of carbon dioxide, and then determine whether there are microorganisms in the blood. However, these detection devices use fluorescence, color or Since the radiolabeled detection devices all use an indirect method to detect the presence of carbon dioxide, the detection takes a long time, the detection cost is high, and the use of multiple disposable culture bottles is required to cause environmental pollution.
