Description
Technical field
The utility model relates to medical detecting Instrument technical field, relates in particular to a kind of microbial rapid detection instrument.
Background technology
Microorganism, comprises the large class biotic populations of bacterium, virus, fungi and protozoan that some are small-sized etc., individual small, closely related with human lives.Relate generally to the numerous areas such as health, medicine, industrial or agricultural, environmental protection.Microorganism comprises following 8 large classes conventionally: bacterium, virus, fungi, actinomyces, Richettsia, mycoplasma, Chlamydia, conveyor screw.
Although most microorganisms are harmless even useful, but there is a large portion to cause, infect or even communicable disease, be called pathogenic microorganism.In all pathogenic microorganisms, especially with bacterium and viral harmfulness maximum.For example Much's bacillus is exactly the well known pathogenic microorganism of a class, and it can invade each organ of whole body, causes the tuberculosis diseases such as pulmonary tuberculosis.The whole world approximately has 2,000,000,000 people to infect tuberculosis at present, increases every year the about 800-1000 ten thousand of tuberculosis case newly, every year because tuberculosis death toll is about 200-300 ten thousand.China's tuberculosis year number of the infected is about 1,300,000 at present, because tuberculosis death toll reaches 130,000 every year, surpasses the summation of other Death of Infectious Diseases number.China is one of 22 popular serious countries of tuberculosis in the whole world, is also one of 27 popular serious countries of resistance to multiple medicines tuberculosis in the whole world simultaneously.China's tuberculosis number of patients occupies second place of the world, is only second to India.Tuberculosis is one of major disease of China's priority control.
In global tuberculosis prevention and treatment control strategy, critical positions that reinforcement laboratory quick diagnosis work is referred.Developing simple, quick, responsive diagnostic techniques, is one of difficult problem urgently to be resolved hurrily during global tuberculosis is controlled.And be to make a definite diagnosis the most special method of pulmonary tuberculosis for the inspection of tulase thalline itself, for example cultivation, if can develop a kind of simple, quick, responsive tulase cultural method, will become the another much progress of diagnosis of tuberculosis technology.
Except the pathogenic microorganisms such as Much's bacillus, cultivation is also to detect in sample whether have one of most popular method of other microorganisms.Conventionally adopt manual method that a corpse or other object for laboratory examination and chemical testing is inoculated in corresponding nutrient culture media, be placed under the condition of objective microbe suitable growth and cultivate, and by the change of visual inspection colonial morphology, nutrient culture media proterties, nutrient culture media color etc., then be aided with certain microorganism discrimination method and judge that objective microbe has or not growth.As Granted publication number is above-mentioned principle for the utility model patent of CN201817474U.Though can accelerate the growth of mycobacterium by Liquid Culture, shortened incubation time, finally still need the appearance of bacterium colony characteristic to judge objective microbe, can not realize interpretation morning to object bacteria, early confirm.
