A microbial sample pretreatment system

Abstract

The invention relates to a microorganism sample pretreatment system which comprises a workbench, a sampling groove and a through groove are formed in the workbench and located on the two sides of a sterilization equipment respectively, and the connecting line of the center of the sampling groove and the center of the sterilization equipment is perpendicular to the length direction of the through groove and passes through the midpoint of the length of the through groove. A clamping mechanism capable of controlling the clamping of the sample tube is arranged above the sampling groove; the scribing equipment comprises an XZ double-axis linear module, an inoculating loop is installed on a sliding block of the Z-axis linear module, and a suction cup driven by a Y-axis linear module is arranged below the workbench. The untreated culture dish bin comprises a top plate and a bottom plate which are fixed through connecting columns, two supporting plates are fixed to the positions, below each arc-shaped lower notch, of the bottom plate through connecting plates, and the faces, connected with the arc-shaped lower notches and the supporting plates, of the connecting plates are arranged to be arc-shaped slopes. According to the invention, full-mechanical operation is utilized to simulate manual microorganism separation, so that risks of infection and inaccurate results during manual operation can be reduced, the working efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a microbial sample pretreatment system. Background technique [0002] Clinical microbial isolation is the most basic and important work in the fields of disease diagnosis, rational use of antibiotics, and hospital infection control in medical institutions. At present, artificial three-zone or four-zone line methods are often used for separation. This method is slow in separation speed. , Artificial contact with microbial samples at close range is inevitable during the separation process, and there is an inevitable risk of infection during the inoculation process. Moreover, due to the rapid changes in the external environment and the increase in population density, the number of clinical samples in the hospital has increased, which has greatly increased the workload of the staff, and the manual operation takes a long time, and the proficiency of the personnel and the stand...

[0002] Clinical microbial isolation is the most basic and important work in the fields of disease diagnosis, rational use of antibiotics, and hospital infection control in medical institutions. At present, artificial three-zone or four-zone line methods are often used for separation. This method is slow in separation speed. , artificial contact with microbial samples at close range is unavoidable during the separation process, and there is an inevitable risk of infection during the inoculation process

Moreover, due to the rapid changes in the external environment and the increase in population density, the number of clinical samples in the hospital has increased, which has greatly increased the workload of the staff, and the manual operation takes a long time, and the proficiency of the personnel and the standardization of the operation are different. , the processing results show certain differences, which also directly affect the accuracy of subsequent test results
