Microorganism culture medium inoculating structure

Abstract

The invention discloses a microbial culture medium inoculation structure and a method for controlling inoculation intensity, including an infrared sterilizer, a sampling cup, a culture medium placed on a culture dish, an inoculation loop damping and sensor detection assembly, an inoculation loop rotating part and an inoculation loop rotation Components, the inoculation loop damping and sensor detection assembly includes an inoculation loop mounting part, and two sets of inoculation loop mechanisms are arranged on the inoculation loop installation part, and the inoculation loop mechanism includes an inoculation loop, an inoculation loop adapter, an inoculation damping spring and Inoculation sensing adjustment screw; ensure that the force of the inoculation loop touching the surface of the medium will not cause various situations that affect the inoculation effect caused by unreasonable pressure; there will be no phenomenon that the medium cannot be inoculated or the medium is scratched ;It will not cause poor marking effect due to high-speed scribing that causes the jumping of the inoculation loop; the separation of the mechanical movement of the inoculation loop and the petri dish requires relatively low mechanical precision, small load, and low cost.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a microorganism culture medium inoculation structure. Background technique [0002] In the field of microbiology, for some suspected bacterial or fungal infections, most of them still use manual inoculation to inoculate samples of human body fluids or living organisms on the culture medium in the petri dish, and then inoculate them in a special culture environment. After 24-48 hours of growth, make a preliminary judgment by observing the growth of bacteria in the petri dish. [0003] There are several problems with manual inoculation: [0004] 1. Manual inoculation operators will come into contact with suspected samples, and the bacteria or fungi in some samples are highly contagious, and there is a great risk of causing infection for operators; [0005] 2. Due to the uneven level of operators in manual inoculation, the effect in the actual inoculation process...

AI Technical Summary

Problems solved by technology

[0004] 1. Manual inoculation operators will come into contact with suspected samples, and the bacteria or fungi in some samples are highly contagious, and there is a great risk of causing infection for operators;

[0005] 2. Due to the uneven level of operators in manual inoculation, the effect in the actual inoculation process will be greatly affected, and the consistency of manual inoculation is particularly poor;

[0006] 3. The speed of manual inoculation is slow, the operator's work intensity is high, and the efficiency is low

[0014] Among them, Jinan Baibo Biotechnology Co., Ltd.: Since the equipment is completely realized by the movement of the inoculation loop during the actual inoculation process, the main structure uses a four-axis robot with relatively high cost. If the inoculation loop is sterilized at high temperature, the efficiency of the equipment will be relatively low, and the applicability of the hospital with a large sample size is too poor. At the same time, the inoculation loop is easily deformed during long-term high-temperature sterilization, which will lead to inoculation failure during long-term use. The phenomenon of reaching the medium or scratching the medium, resulting in abnormal inoculation results, there is no detection mechanism to ensure that the inoculation loop touches the surface of the medium

[0015] Jinan Langmai Biotechnology Co., Ltd.: The company uses the gravity marking method for inoculation. During the actual inoculation, only the petri dish is moving. During the sampling process of the inoculation loop, the inoculation loop needs to be rotated from the sampling position to the marking position. There is a risk of sample dripping to a large extent (the cam mechanism has a great impact force), and this equipment relies on gravity to inoculate. During high-speed inoculation, the inoculation loop will jump on the surface of the medium, and the inoculation effect is not good. In addition, this is to rely on the overpressure of the inoculation loop to ensure the inoculation effect on the surface of the medium, but the actual inoculation loop is bent, and if the amount of bending is too large, it will also lead to the phenomenon that the medium cannot be contacted.
