技术领域 technical field
本实用新型属于医学检验检疫技术领域，具体涉及一种微生物接种储存器，该接种储存器可避免微生物受二次污染。 The utility model belongs to the technical field of medical inspection and quarantine, in particular to a storage device for inoculating microorganisms, which can prevent secondary pollution of microorganisms.
背景技术 Background technique
目前，医疗机构和微生物实验室普遍使用接种环接种，利用接种环挑取标本，放置在琼脂等培养基上分段划线接种获得菌落。这种接种环比较简单，但细菌接种时，取样的好坏往往受到操作者的熟练和环境的影响，特别是从取样到试验之间有一定的时间间隔，往往导致样品受到外界的污染，保证试验的临床标本的有效性的最重要的因素之一是在进行试验前进行有效的保存。因此，在测试样品前其活性成分需被保留一段时间，使实验室测试前保证检验样品的完整性。 At present, medical institutions and microbiology laboratories generally use inoculation loops to inoculate, use the inoculation loop to pick specimens, place them on agar and other media, and inoculate them in sections to obtain colonies. This kind of inoculation loop is relatively simple, but when bacteria are inoculated, the quality of sampling is often affected by the operator's proficiency and the environment, especially there is a certain time interval between sampling and testing, which often leads to external contamination of the sample, ensuring One of the most important factors in the validity of clinical specimens for testing is the effective preservation of the specimens prior to conducting the testing. Therefore, the active ingredient needs to be retained for a period of time before testing the sample, so that the laboratory can ensure the integrity of the test sample before testing.
