Microbial sample processing system

Abstract

The present invention provides a microbial sample processing device, comprising: a machine body provided with a machine chamber and a sealed movable door; and a sealed housing, a stretchable airbag, a sample tray, a mechanical arm, a bar code scanner, a liquefier, culture dishes, a gas-temperature sensor, and a temperature control device which are arranged in the machine chamber, wherein the sample tray is provided with a plurality of sample seats, the sample seats are used for placing the culture dishes, the liquefier is communicated with the culture dishes, each culture dish is provided with culture plates and a streak-inoculation pen used for streak inoculating the sample in the culture dishes from the liquefier on the culture plate. The microbial sample processing device is reasonable in structure, fast and safe, reliable and efficient, can complete the whole process of mixing and liquefying, streak inoculation, dilution and separation, and incubation of microbial community automatically in a one-stop manner, and can replace manual labor and ensure biological safety.

Description

technical field [0001] The present invention relates to a microbial sample processing system, in particular, to the processing of microbial samples in clinical microbiological laboratories, disease control centers, inspection and quarantine and other fields, more specifically, for non-blood microbial samples of urine, feces, and sputum , body fluids, swabs (secretions), and automated processing of water quality, food, excrement and other samples. Background technique [0002] The field of microbiology faces and processes a large number of microbial samples every day. The processing of 15-20% of clinical blood microbial samples has been automated, but more than 80% of clinical non-blood microbial samples are urine, feces, sputum, body fluids, swabs (secretions), water quality, food, Excrement and other samples are still performed by traditional manual operation for more than 100 years. Manual mixing and liquefaction of semi-solid and highly viscous microbial samples such as...

AI Technical Summary

Problems solved by technology

Manual mixing and liquefaction of semi-solid and highly viscous microbial samples such as sputum and feces takes a long time, low efficiency, and high labor costs. Operators are at risk of infection when they come into close contact with samples containing pathogenic bacteria

At the same time, inoculation of various microbial samples by traditional manual streaking is susceptible to human factors and environmental factors. Random and non-standardized operations will affect the effect of bacterial inoculation and culture, and will cause irreversible medical accidents.

[0003] Although there are currently automated microbial sample processing equipment, there are still many defects in the liquefaction of sputum samples with high viscosity and semi-solid microbial samples, such as poor mixing and liquefaction effect, long time, unsatisfactory separation and culture results, and unreasonable structural design. Therefore, it cannot meet the needs of the microbiology field for the automatic processing of microbial samples.
