Problems solved by technology
[0002] There are two kinds of existing drug susceptibility testing methods. One is manual operation, which takes a long time, is inefficient, requires high professional quality of personnel, has strong subjective consciousness, and is prone to errors; the other is relying on automated instruments, such as BD, Baker, etc. Mann and other instruments detect growth or color changes through optical modules, but there is a big defect, that is, it takes a long time, generally takes 8-16 hours, and is expensive, which is a great burden for small and medium hospitals

The invention discloses a microbial drug sensitivity detection image acquisition system which comprises a base station, and a light source adjusting unit, an image acquisition unit and an image position adjusting unit are arranged on the base station. The system has the advantages that the drug sensitivity reaction can be rapidly detected, the cost is low, the image is clear, rapid light-focusing adjustment can be realized, the operation is simple, and the requirement on a light source is not high. Meanwhile, the growth and reproduction conditions of strains can be observed in real time, and the detection efficiency is improved when the method is applied to drug sensitivity detection; the characteristics of large field of view and high resolution are considered, the resolution reaches 0.5 mum, and the field of view is consistent with the size of a CMOS chip, can reach 1 inch and is far higher than that of a microscope objective lens; accurate positioning is achieved, and bacteria shadow image acquisition is facilitated.
Description
technical field [0001] The invention relates to the field of microbial detection, in particular to an image acquisition system for microbial drug susceptibility detection. Background technique [0002] There are two kinds of existing drug susceptibility testing methods. One is manual operation, which takes a long time, is inefficient, requires high professional quality of personnel, has strong subjective consciousness, and is prone to errors; the other is relying on automated instruments, such as BD, Baker, etc. Mann and other instruments detect growth or color changes through optical modules, but there is a big defect, that is, it takes a long time, generally takes 8-16 hours, and is expensive, which is a great burden for small and medium-sized hospitals. Contents of the invention [0003] The purpose of the present invention is to provide an image acquisition system for microbial drug sensitivity detection, aiming at providing a fast and low-cost image acquisition device...
