Description

Multi-channel quantitative inoculator for microbial inoculation

Technical Field

The utility model relates to a microorganism drug resistance detects inoculation technical field, especially relates to a multichannel ration inoculator for microorganism inoculation.

Background

It is currently widely believed that the generation of microbial resistance genes is mostly a result of the long-term evolution of microorganisms under the selective pressure of antibiotics. Therefore, the detection of the MIC value of the antibiotic to the pathogenic microorganism has very important significance for guiding clinical reasonable medication, reducing blindness and reducing antibiotic abuse.

The commonly used Test methods for determining MIC values are the paper diffusion method (Disk diffusion), the Dilution method (Dilution Test) and the E-Test (epsilon meter Test), wherein the Dilution method is divided into the broth Dilution method and the agar Dilution method. The paper diffusion method has more influence factors, such as inoculation bacterial quantity, paper antibacterial drug effectiveness, culture medium components, agar thickness and the like. The influence factors of the test method are the same as those of a paper diffusion method, and the judgment of the intersection of the transverse cutting has certain subjectivity, is high in price and is not beneficial to popularization and use; the conventional agar dilution method is accurate and reliable in experiment, but has high labor intensity and wastes time and labor in inoculation.

In the existing microorganism experiments, especially relating to strain screening experiments, when bacterial liquids of different strains need to be transferred and inoculated to a screening culture medium for culture, the transfer inoculation of a large amount of strain cultures needs to be repeated for multiple times, so that the workload is increased, the efficiency is reduced, and the risk of bacterial contamination is easily increased.

To this end, a multi-channel quantitative inoculator for microbial inoculation was designed to solve the above problems.

Disclosure of Invention

The utility model provides a multi-channel quantitative inoculator for microorganism inoculation, which overcomes the defects and comprises a high-temperature sterilizer, a base and a cover body;

the base is detachably embedded in the high-temperature sterilizer, and a plurality of liquid tanks with upward openings are arranged on the base;

the cover body covers the top of the base, a plurality of inoculating tools extending downwards are detachably inserted into the bottom end face of the cover body in a plugging mode, and a handle extending upwards is fixedly arranged on the top end face of the cover body.

Detailed Description

The following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.

A multi-channel quantitative inoculator for microbial inoculation comprises a high-temperature sterilizer 1, a base 2 and a cover body 4;

the base 2 is detachably clamped in the high-temperature sterilizer 1, and a plurality of liquid grooves 6 with upward openings are formed in the base 2;

the cover body 4 covers the top of the base 2, a plurality of inoculation tools 3 extending downwards are detachably inserted into the bottom end face of the cover body 4, and a handle 5 extending upwards is fixedly arranged on the top end face of the cover body 4.

Further, preferably, the inoculating tool 3 is an inoculating needle or an inoculating loop.

Preferably, the base 2 is cylindrical with a diameter of 90 mm.

The using method comprises the following steps:

preparing a plurality of microbial liquids, respectively adding the microbial liquids into the liquid tank 6 in the base 2, inserting a certain number of inoculating needles or inoculating loops on the bottom end face of the cover body according to requirements, holding the handle 5 by hand, inserting the inoculating loops or inoculating needles into the liquid in the base,

in a multi-channel quantitative inoculator porous base, a certain number of inoculating needles are inserted into a cover body of the multi-channel quantitative inoculator, an inoculating loop or the inoculating needles are inserted into liquid in a liquid groove 6 in a base 2, then the cover body 3 is lifted and inoculated to MH agar culture medium containing medicaments, and the culture medium is inversely incubated.

After the operation is finished, the microbial liquid in the liquid tank 6 in the base 2 is discarded, then the cover body 3 is placed back to the top of the base 2, the base 2 is embedded in the high-temperature sterilizer 1, the switch of the high-temperature sterilizer 1 is opened for high-temperature sterilization, and the high-temperature sterilizer can be reused after the sterilization is finished.

A multichannel ration inoculator one-time operation for microbial inoculation can realize the transfer inoculation of multiple microorganism culture, the simple operation, high efficiency have solved the problem that inoculation work load is huge, transfer inoculation is inefficient in the bacterial strain screening process, the base embedding high temperature sterilizer can heat the sterilization to base and inoculation needle after accomplishing the primary operation, convenient reuse, the practicality is strong.
