Description
Technical Field
[0001] The utility model relates to the technical field of detection equipment, in particular to an antibiotic microbiological detection tube-disc determination mechanism. Background Art
[0002] The tube-and-plate method for measuring antibiotic potency uses the antibacterial efficacy of antibiotics against microorganisms as a measure of potency. It has the advantages of being consistent with the application principle, requiring less dosage and being highly sensitive. The tube-and-plate method is a type of agar diffusion method and has been widely adopted by pharmacopoeias of various countries. As a legal method for biological testing of antibiotics, the tube-and-plate method for measuring antibiotic potency includes six steps: preparing samples and drugs required for the test, filling culture medium, placing a small steel tube, dripping antibiotic solution, culturing strains in double plates, and measuring inhibition zones. When antibiotics diffuse in the bacterial layer culture medium, a natural gradient of antibiotic concentration from high to low is formed, that is, the concentration at the diffusion center is high and the concentration at the edge is low. Therefore, when the antibiotic concentration reaches or exceeds the MIC (minimum inhibitory concentration), the test bacteria is inhibited and cannot reproduce, thus presenting a transparent inhibition zone. According to the derivation of the diffusion law, the logarithm of the total amount of antibiotics is linearly related to the square of the diameter of the inhibition zone.
[0003] If a large number of culture dishes are needed for antibiotic microbiological test tube and plate determination, the culture dishes do not have special tools for transportation and storage, which is quite inconvenient to use. In the prior art, the Chinese patent document with patent number CN213414558 proposes a culture dish storage device, including a support plate and a top cover. Through the cooperation of the support plate, the top cover, the slide bar and the isolation cover device, when placing the culture dish, the culture dish is first placed on the support plate, and when the support plate is full, the isolation cover device is slid onto the culture dish, and the culture dish can be placed on the isolation cover device. It has the characteristics of simple structure and convenient use, but in actual use, there is still a collision between culture dishes, resulting in damage to the culture dishes, and it is not convenient to take the culture dishes. Therefore, the utility model proposes an antibiotic microbiological test tube and plate determination mechanism to meet the needs of improving the transportation and storage of culture dishes.
