Description

Technical Field

[0001] The utility model relates to the technical field of clinical medicine, in particular to a multi-faceted microbial sample separation and cultivation device. Background Art

[0002] In the microbiology laboratories in the fields of clinical medicine, disease prevention and control center inspection and quarantine, food, pharmaceuticals, etc., microbiology operators need to inoculate, separate and culture the patient's sputum, urine, feces, body fluids, blood culture fluids, swabs, imported and exported goods and food. At present, most of the microbiology laboratories in the fields of clinical medicine, disease prevention and control center inspection and quarantine, food, pharmaceuticals, etc. still use traditional manual methods. The disadvantage of manual methods is the pre-treatment of samples. The specimens are manually classified, and then digested, shaken, and enriched one by one according to the category. A series of tedious and complicated pre-treatments, such as digestion-vibration-enrichment, are performed one by one. In addition, each specimen must be manually inoculated and streaked with multiple culture media, and finally the inoculated culture media are placed in different incubators for culture.

[0003] During this process, the operator can easily come into contact with the sample, which can easily cause infection to the operator and seriously threaten the operator's health. Another disadvantage of the manual method is that the manual method cannot perform standardized operations and cannot achieve standardized management and automated processing in the microbial field. Therefore, a multi-faceted microbial sample separation and culture device is proposed.

[0004] A single-plate insert type multi-faceted microbial sample separation and cultivation device disclosed in the announcement number CN205990399U, although, the single-plate insert type multi-faceted microbial sample separation and cultivation device, the bottom end of the double bracket is placed in the second slot plate of the base frame, the bottom of the inoculation rod assembly is placed from the top of the double bracket, and the inoculation loop is close to the bottom of the base frame. The culture dish is placed from the side opening of the double bracket, and the inner bottom surface of the culture dish faces the inoculation loop. The collection bottle is placed in the cylinder of the base frame, and the collection bottle contains the collected sample. Then the whole is vibrated. The collection bottle is crushed, and the liquid flows from the bottom of the base frame to the bottom of the double bracket, and the inoculation loop is stained with liquid. The inoculation rod assembly is lifted up, and the inoculation loop contacts the inner surface of the culture dish with the microbial culture medium during the upward movement. The culture medium on the culture dish will cultivate the growth of the specified microorganism. Use multiple culture dishes, each with different culture media, and different types of microorganisms can be cultured at the same time. It is convenient, safe and fast to operate, and is suitable for standardized management and automated processing in the field of microorganisms.

[0005] Although the above patent uses multiple culture dishes, each with different culture media, and can culture different types of microorganisms at the same time, the operation is convenient, safe, and fast, and is suitable for standardized management and automated processing in the field of microorganisms; however, the device lacks a stirring function. The stirring mechanism can fully mix the microbial sample with the culture medium to ensure that the microbial cells are evenly dispersed in the culture medium, avoid sample sedimentation or aggregation, and ensure that each microbial cell can obtain sufficient nutrition and growth conditions.

[0006] Therefore, it is necessary to invent a multi-faceted microbial sample separation and cultivation device to solve the above problems. Utility Model Content
