Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bagged culture medium sealing and stabilizing devices, and particularly relates to a bracket device for open or unsealed bagged liquid culture media. Background Technique
[0002] Food safety issues concern everyone. With the progress of society, incidents caused by foodborne pathogenic microorganisms have received increasing public attention. Currently, pathogenic microorganisms have become the most serious food safety problem endangering human health. According to reports by the World Health Organization, 150 million people suffer from diarrhea worldwide every year, and 70% of these cases are caused by various pathogenic microorganisms. In China, various foodborne pathogenic microorganisms are also the main causes and factors of foodborne diseases. Foodborne diarrhea diseases and food safety problems caused by various pathogenic harmful microorganisms account for 40% of the total amount of foodborne diseases, and bacteria account for 81.5% of the microbial food pollution pathogens.
[0003] For the detection of pathogenic microorganisms in food, according to the national standard method, usually the sample needs to be homogenized in a bagged liquid culture medium first, and then placed in an incubator for enrichment culture. After culturing for a certain period of time, the enrichment broth is taken and streaked for enrichment culture in a selective medium. After the culture is completed, typical colonies on the selective medium are taken for isolation and purification culture, and the purified culture is used for further PCR or biochemical identification. In the first and second enrichment processes, the self-sealing bag needs to be opened, and after the operation is completed, the self-sealing strip at the opening end of the bagged liquid culture medium is manually pressed until it is completely sealed. In the first enrichment process, after homogenization, the bagged liquid culture medium needs to be placed on a metal bracket with the opening facing up. The above experimental operation process is not easy due to the tight bite of the self-sealing strip of the bagged liquid culture medium. The middle metal partition strip of the metal bracket for placing the bagged liquid culture medium often gets stuck at the bottom of the self-sealing bag, making the operation time-consuming and laborious. In the detection work, due to the large number of samples, this process is repeated, so the overall work efficiency will be reduced, and due to the inconvenient operation, the liquid culture medium containing harmful microorganisms may overflow due to incomplete sealing.
[0004] To sum up, there are some problems in the use of liquid bagged culture media due to the inconvenient sealing and placement operations. Therefore, it is hoped to propose a new structure to solve the above technical problems. Content of the Utility Model
