Microbiological detection culture dish with reference functions

Abstract

The invention discloses a microbiological detection culture dish with reference functions. The microbiological detection culture dish comprises a base, a support seat, a crystal oscillation device, conductive wires and an upper cover. The upper surface of the base is upwardly sunken to form a cavity; the support seat is accommodated in the cavity, and a circular groove is formed in the upper surface of the support seat; the crystal oscillation device comprises a support and a quartz oscillator, the support is of a circular structure, the quartz oscillator is arranged on the support in an embedded manner, wire limiting structures are further respectively arranged at two ends of the support, foil-shaped excitation electrodes are uniformly distributed on the front surface and the rear surface of the quartz oscillator, and joints of the excitation electrodes and external circuits are in the shapes of discs; the conductive wires comprise wires and disc-shaped clamping structures, the disc-shaped clamping structures are connected to the tail ends of the wires and are clamped on the joints in the shapes of the discs to be electrically connected with the joints, and the wires penetrate the wire limiting structures; the upper cover hermetically covers the base and is provided with ports, and culture solution\test specimen solution can flow into the ports or can be drained from the ports. The microbiological detection culture dish has the advantages that the culture time can be shortened, and the detection accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of microorganism detection, in particular to a microorganism cultivation device capable of shortening cultivation time and improving detection accuracy. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, the awareness of food safety is also constantly improving. In the past, as a method for judging whether spoilage bacteria are contained in food or beverage, there are machine-based methods such as immunoassay, ELISA, gas chromatography mass spectrometry, liquid chromatography mass spectrometry, etc., but the pretreatment of the measurement It is complicated, and the accuracy of judgment cannot be said to be sufficient. Thus, it generally takes a long time to cultivate spoilage bacteria. [0003] Use techniques that include labeling the microorganisms to highlight the contrast between the light emitted by the microorganisms and the ...

Problems solved by technology

The disadvantage of these methods is that relatively long incubation periods are required in order for the colonies formed on the agar medium to be detectable with the naked eye

The disadvantage of these methods is that several kinds of DNA strands are required, that is, several kinds of microorganisms, generally at least dozens of microorganisms, which are not as sensitive as growth-based methods.

[0005] The method of cultivating the microorganisms to be detected on agar medium is relatively common, but its disadvantage is that the cultivation time is too long. How to shorten the cultivation time and improve the efficiency has become a bottleneck that needs to be broken through
