Embodiment Construction

[0059] The invention provides an intestinal microbiological sampling device which can complete the process of feces sample processing under relatively anaerobic conditions, and can meet the research requirements of intestinal anaerobic microbes. Before setting forth the specific embodiments, it should be noted that:

[0060] (1) Although most of the embodiments are described with stool samples as an example, those skilled in the art should be able to understand that the sample dilution tube and the corresponding sampler in the present invention can also be applied to anaerobic microorganisms in other application scenarios detection, such as: the detection of certain cultural relics in archaeological applications.

[0061] (2) Those skilled in the art should be able to understand that the sample dilution tube and the corresponding sampling kit in the present invention can also be applied to the detection of other mammalian feces samples.

[0062] (3) The main innovations in th...

Abstract

The invention provides a sample dilution tube and a sampling kit using the same. The sample dilution tube comprises: a tube body; the sealing piston is sleeved on the inner side of the pipe body in a free sliding manner; the sealing cover covers the upper part of the tube body, and a sample introduction channel is formed on the sealing cover; wherein a diluent space is defined by the tube body, the sealing piston and the sealing cover, and when a sample is squeezed into diluent from the sample injection channel, the sealing piston can automatically slide to increase the volume of the diluent space. The opportunity that the sample and the diluent are in contact with the outside air is minimized, the anaerobic environment is kept, and the separation culture efficiency of anaerobic and facultative anaerobic microorganisms in the excrement sample is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sample dilution tube and a sampling kit using the same. Background technique [0002] There are a large number of microorganisms in the intestinal tract, which are closely related to the health of animals. The goal of research on intestinal microorganisms is to understand the symbiotic relationship between animals and microorganisms, as well as the relationship between changes in microbial flora and the progress of diseases, so as to improve the development and utilization of microorganisms. Human and animal health lay a theoretical foundation. The study of intestinal microbes usually obtains effective information through the study of fecal microbes. Sampling and diluting feces, and then obtaining microbial species through isolation and culture is a common technical means in the study of intestinal microbes. Quantitative sampling and quantitative dilution of stool samples are he...
