A solid-state sample processing device for microbial detection

Abstract

The invention discloses a solid-state sample processing device for microorganism detection, which comprises a bottom plate and a chopping box, the chopping box is arranged above the bottom plate, and a plurality of rectangularly distributed columns are fixedly connected to the bottom side of the chopping box , one end of each column away from the chopping box is fixedly connected to the bottom plate, the side cover of the chopping box close to the bottom plate is provided with a sample plate, and the side of the sample output plate close to the bottom plate is fixedly connected with a plurality of connecting plates , the side of the chopping box close to the bottom plate is fixedly connected with a plurality of supports corresponding to the connecting plate. The invention has a novel structure, and uses the mutual engagement of the blades on the pair of first rotating shafts to chop the sample, realizes the power transmission through the mutual meshing of the second gear and the third gear, and realizes the dilution through the sliding connection between the crank and the semicircular groove plate The shaking effect of the bottle, the exposure time of the whole process to the outside world is extremely short, which ensures the accuracy of the later detection of microorganisms.

Description

technical field [0001] The invention relates to the field of microorganism detection devices, in particular to a solid-state sample processing device for microorganism detection. Background technique [0002] Microorganisms include bacteria and fungi. These microorganisms will have adverse effects on the human body, and some microorganisms are pathogenic bacteria, which are extremely harmful, so the detection of microorganisms is essential. The detection of microorganisms is conducive to the products meeting the standards required by the country, and it can also make the shelf life of the products reach the rated required time. Therefore, food and drugs are required to carry out microbial detection operations. However, when the user needs to perform microbial detection on solid samples, it is necessary to pre-process the solid samples. For the pre-treatment of solid samples, there are currently crushing and homogenizing methods, shearing and shaking methods, grinding methods...

Problems solved by technology

Although the implementation of these five methods is carried out in the aseptic laboratory, and they are basically manually operated, the samples are exposed to the outside world and have a long contact time with the operator. Even if the sterilizing effect of the aseptic laboratory is good, the It is inevitable that the culture medium of individual microorganisms needs to be removed, which delays the detection efficiency and affects the detection results. At the same time, the shaking process of the dilution bottle needs to meet the shaking at least 50 times, and the amplitude must be greater than 40 cm. Deplete power
