Description

Technical Field

[0001] The utility model belongs to the technical field of culture vessels, and in particular relates to a culture vessel for in vitro drug sensitivity experiments of digitally visualized antibacterial drugs. Background Art

[0002] Current status of in vitro susceptibility testing of antimicrobial drugs: There are many commonly used methods for susceptibility testing, including the disc diffusion method, dilution method, and E-test method. Taking the disc diffusion method as an example, this method is to stick a piece of paper containing a quantitative antimicrobial drug on an agar plate inoculated with the pathogen to be tested. The antimicrobial drug on the paper will diffuse into the surrounding agar, forming a gradually decreasing drug concentration gradient. Since pathogenic bacteria have different sensitivities to various antimicrobial drugs, inhibition rings of different diameters will appear around the drug paper to inhibit the growth of pathogens. According to the presence and size of the inhibition ring, it can be determined whether the test bacteria are resistant or sensitive to the antimicrobial drug. The sensitivity evaluation of antimicrobial drugs is mainly carried out by measuring the size of the inhibition ring of the antimicrobial drug on the MH culture medium, and then judging whether it is resistant or sensitive according to the CLSI standards.

[0003] Most of the existing culture vessels for drug sensitivity tests can only perform simple drug sensitivity tests. In subsequent measurements, additional measuring tools such as vernier calipers are required to measure the diameter of the inhibition zone. The overall operation is relatively cumbersome. How to organically combine the overall culture of the drug sensitivity test and the subsequent measurement has become an urgent problem to be solved. Therefore, a digital visualization culture vessel for in vitro drug sensitivity test of antimicrobial drugs is needed to assist in solving this problem. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] This specific embodiment is a culture vessel for digital visualization of in vitro drug sensitivity test of antibacterial drugs, such as Figure 1 and Figure 2As shown, the digital visualized culture vessel for in vitro drug sensitivity test of antimicrobial drugs includes a culture dish bottom cover 1 and a top cover 8 covering the top of the culture dish bottom cover 1, the culture dish bottom cover 1 is provided with a holding cavity for holding a medium, the culture dish bottom cover 1 is provided with a holding cavity for holding a medium, and the bottom of the culture dish bottom cover 1 is engraved with scale lines 6 for marking measurements, the zero scale of the scale lines 6 is located at the middle section of the scale lines 6, the scales on the scale lines 6 extend from the middle section to both sides, a positioning hole 7 is opened at the center of the corresponding scale lines 6 in the holding cavity, six scale lines 6 are provided, and the six scale lines 6 are arranged in a circular array with the axis of the culture dish bottom cover 1 as the center, the angle between two scale lines 6 is 60 degrees, and the positioning hole 7 is located at the zero scale position of the scale lines 6.

[0027] By engraving the scale lines 6 at the bottom of the culture dish bottom cover 1, during operation, by pre-processing the bottom of the culture dish bottom cover 1 with auxiliary scales, the size of the inhibition zone can be effectively understood by directly observing the scales at the position of the scale lines 6 when measuring the size of the inhibition zone later, and subsequent measurement by a vernier caliper or the like can be avoided as much as possible, thereby improving the subsequent overall measurement work efficiency and reducing the overall test cost later.

[0028] Among them, the edge of the drug-sensitive paper with the drug is 3 cm away from the axis point of the culture dish bottom cover 1, and the scale 0 point on each scale line 6 is 27 mm away from the axis point of the culture dish bottom cover 1. The scale inward can be made full of 27 mm, and the scale outward can be made to the edge. The overall diameter of the culture dish bottom cover 1 is about 85 mm.

[0029] Reference Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the culture dish bottom cover 1 is protrudingly provided with a protruding seat 2, the bottom of the top cover 8 is set at the top of the protruding seat 2, a plug-in slot 3 is opened between the two scale lines 6 at the bottom of the culture dish bottom cover 1, a plug-in board 4 is installed at the plug-in slot 3, and a receiving slot 42 for placing the corresponding name is opened at the top of the plug-in board 4, and limit strips 31 are symmetrically protruding on both sides of the plug-in slot 3, and limit slots 41 are symmetrically opened on both sides of the plug-in board 4, and the limit strips 31 are plugged in with the limit slots 41.
