Collection and protection device for microbial nucleic acid samples

Abstract

The invention discloses a collection and protection device for microbial nucleic acid samples, and belongs to the technical field of microbial scientific research instruments. The collection and protection device comprises a sampling head and a protection shell, wherein a supporting base is fixedly installed at the bottom of the protection shell, an arc-shaped rod is fixedly connected to the inner wall of the protection shell, the arc-shaped rod is sleeved with an arc-shaped block connected with the arc-shaped rod in a sliding mode, first springs are fixedly connected between the two sides of the arc-shaped block and the inner walls of the protective shell, the arc-shaped rod is sleeved with the two first springs, a driving mechanism is arranged between the arc-shaped block and the inner bottom of the protection shell, a supporting block is fixedly connected to the upper end of the arc-shaped block, and a mixing pipe is arranged above the supporting block. According to the device, a clean and sanitary environment can be provided for the samples, so that the samples are not easily influenced by the external environment, meanwhile, the mixing pipe and a liquid injection pipe can be protected, so that the mixing pipe and the liquid injection pipe are not easily damaged, and meanwhile, the samples and the microbial nucleic acid protection liquid can be fully and uniformly mixed.

Description

technical field [0001] The invention relates to the technical field of microbial scientific research equipment, in particular to a collection and protection device for microbial nucleic acid samples. Background technique [0002] Microorganisms are ubiquitous, huge in number and diverse, and are closely related to human life and the surrounding environment. Microorganisms have many uses and have been applied to many fields such as industry, agriculture, medicine and food. Therefore, it is extremely important to continue to study the composition, types and functions of microorganisms in the human environment. At present, the collection and transportation of microbial nucleic acid samples is one of the important links in the research of microorganisms in clinical and scientific research. [0003] During the collection and transportation of microbial nucleic acid samples, if there is a lack of suitable sample collection devices and transportation conditions, it will not only i...

AI Technical Summary

Problems solved by technology

[0003] During the collection and transportation of microbial nucleic acid samples, if there is a lack of suitable sample collection devices and transportation conditions, not only will the workload of the staff be increased, but the nucleic acid of microorganisms will be degraded, resulting in the failure of subsequent research.

[0004] In the prior art, the clinical collection device for microbial metabolite samples cannot be effectively protected during transportation, and some operations are distributed, which is inconvenient to operate; therefore, we have designed a collection and protective device
