Description

Auxiliary device for photographing microbial colonies

Technical Field

The utility model relates to the field of medical technology, especially, relate to an auxiliary device that microbial colony used of shooing.

Background

The growth characteristics (including colony size, color, appearance, edge morphology, luster, hemolytic cycle and the like) of the microbial colony in the culture dish are important bases for classifying and identifying the microbes. Therefore, the observation and photographing of colony morphology play an important role in the routine work of clinical microbiology examination, as well as teaching and scientific research. In general, a worker directly takes a picture of a bacterial colony in a culture dish in a close range by using a photographing device (such as a smart phone or a smart pad with a photographing function, a camera, etc.), but the following problems may occur: 1. blurring of the image due to hand trembling; 2. poor light or angle adjustment affects the photographing effect; 3. reflecting light on the surface of the culture medium to generate a reflection; 4. close-up photographs can create a biohazard.

For avoiding the appearance of above-mentioned problem, chinese patent number is CN208857263U, the name is "a novel device for bacterial colony is shot" discloses a device, and it includes the cylinder case, the upper portion of cylinder case is equipped with the incandescent lamp, the upside of incandescent lamp is equipped with the ultraviolet lamp, open the top middle part of cylinder case has the hole of shooing, the lateral wall bottom of cylinder case is equipped with the push-and-pull door. The device can guarantee the quality of shooing, can not make the culture easily take place the pollution because of external environment influence in the process of shooing moreover, but the device still has the problem of at least three aspects:

first, some clinically important pathogens such as staphylococcus aureus, group a streptococcus, group B streptococcus, listeria monocytogenes, streptococcus pneumoniae, clostridium perfringens, etc. may produce hemolysin in Columbia Blood Agar (CBA) plates, since CBA plates contain 5% sheep blood, hemolysin destroys red blood cells in sheep blood, hemolysin forms a hemolysin ring around colonies, which can be classified into complete hemolysis (β hemolysis, forming a completely clear and transparent hemolysin ring around colonies, such as staphylococcus aureus, etc.) and grass green hemolysis (α hemolysis, forming a narrow, grass green hemolysin ring around colonies, such as streptococcus pneumoniae, etc.) according to different degrees of hemolysis, since bacteria produce different types of hemolysis rings are very important identification features, such as staphylococcus aureus is a clinically important pathogen, while staphylococcus epidermidis is generally considered to have no clear significance, colony morphology is very similar, but staphylococcus aureus can produce β hemolysin ring, while staphylococcus epidermidis group B is a clinically important pathogen, while staphylococcus epidermidis is generally considered to be opaque, colony morphology is considered to be very similar to a colony of a streptococcus pneumoniae, and thus it is considered to be a very difficult to observe bacterial colony infection in situ by light, such as a narrow, and thus it is generally considered to be a human enterobacter enteron colony, even if bacteria can be a colony, it is a human, it is considered that bacteria can be a human, it is very difficult to observe a human, it is a human.

Secondly, the photographing device takes a photograph through the photographing hole at the top of the cylindrical box, the photographing device is held by hands or is horizontally placed at the top of the cylindrical box (namely, the photographing angle is vertical to the vertical plane), and if the photographing device is held by hands, the problem of image blurring caused by hand shaking cannot be solved; if the camera is horizontally placed on the top of the cylindrical box, the photographing device cannot be fixed, and the photographing angle cannot be adjusted. For some important colony characteristics, such as a protrusion (for example, a colony of klebsiella pneumoniae is obviously protruded, and a colony of escherichia coli is flat), a depression (a colony of streptococcus pneumoniae is depressed on a CBA plate due to self-coagulation), etc., it is usually necessary to adjust a photographing angle to achieve an optimal stereoscopic effect, so that when the photographing device is laid flat, only a planar effect can be photographed, and the stereoscopic colony characteristics of the protrusion, the depression, etc. cannot be reflected.

Thirdly, in order to achieve the best photographing effect, the brightness of the light source needs to be adjusted, and the device cannot adjust the brightness of the light source.
