Novel transplantation-free cover glass for culturing bacterial colonies and preparation instrument of novel transplantation-free cover glass

Abstract

The invention discloses a novel transplantation-free cover glass for culturing bacterial colonies and a preparation instrument of the novel transplantation-free cover glass, and relates to the technical field of medical science instruments. A semi-circular hole is formed in one side of the novel transplantation-free cover glass for culturing bacterial colonies, and a plurality of gaps extend around the semicircular hole, so that fungus growth is facilitated. The preparation instrument of the novel transplantation-free cover glass for culturing bacterial colonies comprises a trimming part, a shaping part, a control part and a clamping part, and the trimming part comprises a main box, a semicircular outer ring, a semicircular inner block, a slotted outer ring and a slotted inner block. According to the preparation instrument of the novel transplantation-free cover glass for culturing bacterial colonies, the semicircular hole is formed in the cover glass, and the plurality of gaps extend around the semicircular hole, so that bacterial colonies grow on the surface of the cover glass, the control part is arranged to position and move the cover glass, and the cover glass is trimmed through the semicircular outer ring, the semicircular inner block, the slotted outer ring and the slotted inner block which are arranged in the main box.

Description

technical field [0001] The invention relates to the technical field of medical scientific instruments, in particular to a new type of cover glass without transplantation for cultured colonies and a preparation device thereof. Background technique [0002] A cover slip is a thin, flat piece of glass of transparent material, usually square or rectangular, about 20 millimeters (4 / 5 inch) wide and a fraction of a millimeter thick, placed over the object being viewed with a microscope. The object is usually placed between a coverslip and a somewhat thicker microscope slide, which rests on the stage or slide holder of the microscope and provides physical support for the object and the slide. Small fungal culture is the best method to identify superficial fungi or filamentous fungi. With small culture methods, the growth position and formation process of spores and microconidia can be observed, and the complete hyphae and original hyphae can be observed. .

AI Technical Summary

Problems solved by technology

[0003] To sum up, the following technical problems exist in the process of observing the morphology of fungi at present: 1) medical researchers grow fungi on glass slides or coverslips to facilitate microscope observation, and cultivate small colonies of fungi, but the cultivation steps are cumbersome and difficult to operate. It is troublesome and complicated, which affects the research efficiency of medical staff; 2) It is convenient and quick to cultivate fungi through the medium, but when the colonies on the medium are placed on slides or coverslips, the branching and morphology of the colonies will be destroyed, which will affect the later observation under the microscope , when the cover glass is placed in the culture medium to directly culture the colony, since there is no air between the cover glass and the medium as a growth support, the colony can only grow along the periphery of the cover glass and cannot grow on the surface of the cover glass; 3 ) When the colony grows on the surface of the cover glass by artificially trimming the gap of the cover glass, it will cause irregular trimming of the cover glass and affect the growth of the colony. The use of mold trimming will cause the trimming of the cover glass to break due to positioning deviation and cannot be used.
