Description

technical field [0001] The invention belongs to the field of Escherichia coli detection, in particular to a detection device for rapid detection of Escherichia coli. Background technique [0002] Escherichia coli is a resident bacterium in the intestines of humans or animals. It is widely found in food, drinking water and other environments that humans depend on for survival. The detection of E. coli and other harmful microorganisms in food is an important part of food hygiene and epidemic prevention. , It is also one of the important indicators for the self-inspection of food manufacturers. At present, the equipment used to test E. coli and other harmful microorganisms in food includes a large number of glass instruments, high-pressure sterilization equipment, flat plates, ultra-static tables and constant temperature shakers, etc., relying on the method of cultivating target microorganisms to determine whether the food is qualified . The shortcomings are: first, the opera...

Problems solved by technology

The shortcomings are: first, the operation steps are cumbersome, time-consuming and laborious; second, the production of each plate requires at least 10-15mL of medium, which is a big waste; third, the cultivation time is long, and the results cannot be obtained quickly

The shortcomings are: first, the operation steps are cumbersome, time-consuming and laborious; second, the production of each plate requires at least 10-15mL of medium, which is a big waste; third, the cultivation time is long, and the results cannot be obtained quickly

At present, there are also some rapid detection equipment, such as the bacterial counting system established by the impedance method, the bioluminescence rapid detection instrument using the ATP luciferase, the automatic bacterial automatic identification system using the biochemical identification method, etc., this type of equipment is expensive , needs to be equipped with a special laboratory, the operation requirements are strict, and it is difficult to promote
