Microorganism examination extractor

Abstract

The invention discloses a microorganism examination extractor. The extractor comprises an examination box, a servo motor is fixedly installed in the examination box, a rotating box is fixedly installed at a driving end of the servo motor, an oscillating mechanism is installed in the rotating box, a plurality of lower liquid pipes are fixedly installed on the rotating box, a plurality of liquid discharge pipes are fixedly mounted on the examination box, a top plate is fixedly mounted on the examination box, two liquid taking pipes are mounted on the top plate through two rotating mechanisms, extraction pipes are fixedly mounted at lower parts of the two liquid taking pipes, the two extraction pipes are located in the rotating box, a liquid inlet pipe is fixedly mounted on the top plate, and a sealing cover is mounted on the liquid inlet pipe in a threaded manner. The microorganism examination extractor has advantages that a culture solution can be oscillated, so that microorganisms are uniformly distributed, sampling uniformity is improved, rapid multi-position sampling can be carried out, external pollution is avoided during sampling, and examination accuracy is relatively high.

Description

technical field [0001] The invention relates to the technical field of microbiological testing, in particular to a microbiological testing extractor. Background technique [0002] When the existing laboratory is carrying out the culture and observation experiment of microorganisms, the culture solution is usually injected into the extractor first, and then the microorganisms are put into the culture solution to cultivate it, and the culture solution in the extractor is kept at any time during the cultivation process. Extraction and collection are carried out to facilitate the observation and inspection of microbial growth; [0003] The existing extractor usually has the following deficiencies during use: [0004] 1. When the existing device extracts microorganisms, it cannot vibrate the culture solution, so that the microorganisms will accumulate in some areas of the culture solution instead of being evenly distributed, resulting in too many or too many microorganisms in th...

Problems solved by technology

[0004] 1. When the existing device extracts microorganisms, it cannot vibrate the culture solution, so that the microorganisms will accumulate in some areas of the culture solution instead of being evenly distributed, resulting in too many or too many microorganisms in the culture solution taken out. less, it will affect the test results;

[0005] 2. When the existing device extracts microorganisms, the device is usually opened as a whole for extraction. This method will cause microorganisms or impurities in the external air to enter the culture solution in the device during the extraction process, which will affect the test results;

[0006] 3. The existing device cannot quickly complete the collection and separation of the culture solution, nor can it flexibly collect the culture solution in different areas of the extractor, the collection efficiency is low, the collection effect is not good, and it has certain limitations;
