Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drug analysis, in particular to a novel drug-sensitive paper patch device. Background Art
[0002] In hospital clinical and medical research experiments, it is often necessary to test the sensitivity of drugs. Different bacteria have different resistance to different drugs, so drug sensitivity tests are often required. Now, fully automatic coating instruments are gradually used in clinical practice. They can stick filter paper containing quantitative antimicrobial drugs on the culture dish on the agar surface inoculated with test bacteria. The drug in the paper diffuses in the agar. As the diffusion distance increases, the concentration of the antimicrobial drug decreases logarithmically, thereby forming a concentration gradient around the paper to determine the sensitivity of the drug to bacteria. The diameter of the inhibition zone of different antimicrobial drugs may be different due to the influence of the diffusion rate of the drug in agar. The size of the inhibition zone can reflect the sensitivity of the test bacteria to the measured drug and is negatively correlated with the minimum inhibitory concentration (MIC) of the drug to the test bacteria, that is, the larger the inhibition zone, the smaller the MIC. The most basic of all these tests is to stick the drug-sensitive paper on the culture medium of the culture dish. In the past, manual operation was generally used, which was labor-intensive, easy to infect, and could not achieve automatic detection. Therefore, it is very beneficial to invent a novel drug-sensitive paper patch device. Summary of the invention
