Efficient escherichia coli testing device

Abstract

The invention belongs to the technical field of microbiological detection equipment, and particularly relates to an efficient escherichia coli testing device. The testing device comprises a box body and a box cover hinged to the box body, the interior of the box body is divided into a heating chamber, an inoculation chamber and a reaction chamber through two partition plates, the box body is sealed through a top plate, and the inoculation chamber is located between the heating chamber and the reaction chamber; a fixed cylinder is arranged on the top plate in a penetrating mode, and pull rods are inserted into the fixed cylinder; an inoculation device is arranged, the inoculation box comprises an epsilon-shaped cylinder, and the middle of the epsilon-shaped cylinder is communicated with thefixed cylinder; according to the invention, the pull rod is arranged in the fixed cylinder, a melting groove is formed in the pull rod, after a culture medium is placed in the melting groove, the pull rod is moved, the melting groove is sealed in the fixed cylinder by the pull rods on the two sides of the melting groove, then the culture medium is inoculated with a reagent which does not make contact with outside air through the inoculation device, the culture medium and the reagent are not affected by bacteria in air, and detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of microorganism detection equipment, in particular to a high-efficiency test device for Escherichia coli. Background technique [0002] Escherichia coli, also known as Escherichia coli, is an opportunistic pathogenic bacterium that can cause gastrointestinal infections or urinary tract and other local tissue and organ infections in humans and various animals under certain conditions. The normal resident bacteria in the airways, a small fraction of which cause disease under certain conditions. The serotype of Escherichia coli can cause gastrointestinal infections in humans or animals, mainly caused by specific pili antigens, pathogenic toxins, etc. In addition to gastrointestinal infections, it can also cause urinary tract infections, arthritis, meningeal Inflammation and sepsis infection, etc. Escherichia coli is a resident bacterium in the intestinal tract of humans or animals, and widely exists in food, ...

AI Technical Summary

Problems solved by technology

[0003] When testing Escherichia coli, it is necessary to put the test sample on the culture medium, and to make the cultured test sample undergo a color reaction by dripping the test solution to observe whether there is Escherichia coli. After making the culture medium, it is necessary to put the culture medium Inoculate near the alcohol lamp to prevent bacteria in the air from contaminating the culture medium. Especially when testing outdoors, when there is wind, when the bacteria in the air reach the alcohol lamp, the alcohol lamp will be affected by the wind and cause air pollution. The temperature is low, and the sterilization effect is small; when the staff observes the internal test results through the observation window, due to the temperature difference, water vapor will condense on the inner surface of the observation window, which will affect the observation of the staff. At the same time, the interior of the fixed cylinder is relatively airtight and it is difficult to clean the inner surface of the observation window.
