Description
技术领域technical field
本发明是一种基于三点法的微生物手持接种装置，属于微生物接种技术领域。The invention is a hand-held microorganism inoculation device based on a three-point method, belonging to the technical field of microorganism inoculation.
背景技术Background technique
疫苗是指用各类病原微生物制作的用于预防接种的生物制品。其中用细菌或螺旋体制作的疫苗亦称为菌苗。疫苗分为活疫苗和死疫苗两种。常用的活疫苗有卡介苗，脊髓灰质炎疫苗、麻疹疫苗、鼠疫菌苗等。常用的死疫苗有百日咳菌苗、伤寒菌苗、流脑菌苗、霍乱菌苗等。Vaccines refer to biological products made from various pathogenic microorganisms for vaccination. Vaccines made of bacteria or spirochetes are also called bacteriocin. There are two types of vaccines: live vaccines and dead vaccines. Commonly used live vaccines include BCG, polio, measles, and plague. Commonly used dead vaccines are pertussis vaccine, typhoid vaccine, meningitis vaccine, cholera vaccine and so on.
不同疫苗的生产时间各不相同，有的疫苗可能需要22个月才能生产出一个批次。疫苗的开发是一个漫长而复杂的过程，且成本很高。接种疫苗是预防和控制传染病最经济、有效的公共卫生干预措施，对于家庭来说也是减少成员疾病发生、减少医疗费用的有效手段。The production times for different vaccines vary, and some vaccines can take up to 22 months to produce a batch. The development of a vaccine is a long and complex process, and it is costly. Vaccination is the most economical and effective public health intervention for the prevention and control of infectious diseases, and it is also an effective means for families to reduce the occurrence of diseases among members and reduce medical costs.
在目前现有技术水平，当我们在实验室做微生物疫苗实验时，经常会使用“三点法”(此法即把少量的微生物接种在平板表面上，成等边三角形的三点，让它各自独立形成菌落后，来观察、研究它们的形态。)来培养微生物，及在培养基上固定的三个位置上进行接种。正常情况下，如果需要接种几次，就需要用接种针分别灭菌和接种几次才能完成一个培养基上的接种，这样做给实验操作带来了很大的麻烦，而且往往不能保证灭菌与接种的时间完全一致。At the current state of the art, when we do microbial vaccine experiments in the laboratory, we often use the "three-point method" (this method is to inoculate a small amount of microorganisms on the surface of the plate, forming three points of an equilateral triangle, let it After the colonies were formed independently, their morphology was observed and studied.) to culture microorganisms, and inoculated at three fixed positions on the medium. Under normal circumstances, if you need to inoculate several times, you need to use the inoculation needle to sterilize and inoculate several times to complete the inoculation on one medium, which brings a lot of trouble to the experimental operation, and often cannot guarantee sterilization. exactly the same time as inoculation.
