Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biological sample analysis, in particular to a novel culture dish transfer device. Background Art
[0002] In hospital clinical and medical research experiments, it is often necessary to collect and analyze the biological samples of patients. First, the biological samples (especially liquid biological samples, such as sputum) are separated and cultured clinically. The laboratory technician mixes the sample with the digestive fluid. After stirring for a certain period of time, the sputum sample becomes a homogenized sample. Then the homogenized sample is streaked and inoculated on a culture dish containing a solid culture medium for separation and culture, so as to obtain bacterial colonies, and further perform bacterial identification and drug sensitivity testing. In the past, manual detection was used, which had a large workload and was easy to cause bacterial infection to the test personnel. Now, a fully automatic coating instrument is gradually used clinically, which can affix a filter paper containing a quantitative antimicrobial drug to a culture dish on the surface of an agar inoculated with a test bacterium. The drug in the paper diffuses in the agar, and the concentration of the antimicrobial drug decreases logarithmically with the increase of the diffusion distance, thereby forming a concentration gradient around the paper. However, the automatic delivery of the culture dish requires a matching device to be realized, so it is very beneficial to invent a new type of culture dish transfer device. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a novel culture dish transfer device, which can conveniently transfer the culture dish to realize automatic coating detection.
[0004] The technical scheme adopted by the utility model is as follows: it comprises a fixed plate (1), a rotating bracket (2) is fixed on the fixed plate (1), and is characterized in that: the rotating bracket (2) is composed of an upper fixed plate (3) and a lower fixed plate (4), a support rod (5) is arranged between the upper fixed plate (3) and the lower fixed plate (4), culture dish placement rack holes (6) are opened at corresponding positions on the upper fixed plate (3) and the lower fixed plate (4), a culture dish placement rack (7) is arranged in the culture dish placement rack hole (6), a culture dish (8) is arranged in the culture dish placement rack (7), and a lifting device (11) is arranged below the culture dish placement rack hole (6) of the lower fixed plate (4).
[0005] A better technical solution of the utility model is: a rotating shaft (9) is installed in the middle of the rotating bracket (2), a rotating motor (10) is installed at the bottom of the rotating shaft (9), and the output shaft of the rotating motor (10) is connected to the rotating shaft (9); the lifting device (11) comprises a fixed rod (12), a connecting piece (13) is fixed to the fixed rod (12), the connecting piece (13) is connected to a push rod (14) through a rack, and a driving motor (15) is fixed to one side of the connecting piece (13); the diameter of the culture dish is 90 mm or 150 mm.
[0006] The utility model has the advantages of simple structure and convenient use, and can conveniently transport the culture dish to realize automatic coating detection. BRIEF DESCRIPTION OF THE DRAWINGS
