Abstract

The invention discloses a microbial quantitative sampling device used for medical detection. The device includes a threaded rod. The threaded rod penetrates inside a sampling tube. A uniform-speed sample auxiliary-output device is mounted at an upper end of the sampling tube in cooperation with the threaded rod. A position limiting nut is arranged on the threaded rod in a sleeving manner. A pressure plate is fixed at the bottom of the threaded rod through a first bearing seat. The pressure plate is arranged inside the sampling tube. According to the microbial quantitative sampling device usedfor medical detection of the invention, a splitting-type nut arranged on the uniform-speed sample auxiliary-output device is closed to form a complete nut after being squeezed, and then carries out threaded transmission with the threaded rod to realize uniform-speed sample output, and accuracy of processing a sample is improved in an auxiliary manner; and the position limiting nut can adjust a position on the threaded rod, and cooperation with position limiting of the uniform-speed sample auxiliary-output device can be realized in sampling to facilitate quantitative sampling.

Description

technical field [0001] The invention relates to a microbial quantitative sampling device, in particular to a microbial quantitative sampling device for medical testing. Background technique [0002] The structure of human intestinal flora has significant individual differences, and molecular methods can be used to find molecular markers of healthy intestinal common flora to make a more accurate diagnosis of intestinal diseases; in food research, due to the The emergence of drug-resistant bacteria, the contamination of food by fecal bacteria, the impact of drinking water, food and feed additives, and veterinary drug residues on the intestinal flora, and the application of probiotics in the prevention and treatment of gastrointestinal flora disorders, etc. Research on the microecology of intestinal flora is gaining more and more attention. [0003] Microbiological detection is to understand the microbial flora structure of human intestinal flora, soil ecosystem and lake ecosy...
