Experimental device for bacterial infection in cell culture dishes

Abstract

The invention provides a bacterial infection experiment device for cell culture dishes. The device comprises an airtight bacterial infection cabin mounted on a movable support leg frame, wherein the airtight bacterial infection cabin is provided with a sealing cabin door and a cabin door handle lock on the front surface, the sealing cabin door can be opened / closed and locked, a plurality of in-cabin trays are arranged on the cabin rear wall in the bacterial infection cabin and can accommodate the cell culture dishes to be exposed in the infection experiment environment, an atomization diffuser is connected to the upper part of the bacterial infection cabin, atomizes and diffuses a solution containing bacteria and conveys the solution to the cell culture dishes for an exposure infection experiment, the lower end of the bacterial infection cabin is connected to a waste gas treater in a sealed manner, the waste gas treater disinfects, sterilizes and efficiently filters waste gas from the bacterial infection cabin, safe emission of exhaust is guaranteed, and an ultraviolet disinfection lamp in the bacterial infection cabin is used for sterilization and disinfection after the experiment is completed. The bacterial infection experiment device has the benefits as follows: a safe and convenient bacterial infection experiment device having a simple structure and used for the cell culture dishes is developed, and the difficulty of automatic operation and sealed isolation in bacterial infection research work of the cell culture dishes is solved.

Description

technical field [0001] The invention relates to a cell culture dish bacterial infection experiment device. Background technique [0002] In scientific research involving the environment, medicine, military, aviation and other fields, it is often necessary to carry out bacterial infection experiments on cell culture dishes. The experiments have strict requirements on the infection environment, and must be uniformly cultured without bacterial contamination. Currently, cell culture The method of bacterial infection experiment in the dish is generally artificial dripping and incubator cultivation. The amount of dripping during the whole process cannot be guaranteed to be accurate and consistent. The infection environment is not airtight and there is no disinfection and sterilization measures, so there will be miscellaneous bacteria during the cultivation process. It can not guarantee the accuracy of the follow-up experiments on the cell culture dish after bacterial infection, an...

[0002] In scientific research involving the environment, medicine, military, aviation and other fields, it is often necessary to carry out bacterial infection experiments on cell culture dishes. The experiments have strict requirements on the infection environment, and must be uniformly cultured without bacterial contamination. Currently, cell culture The method of bacterial infection experiment in the dish is generally artificial dripping and incubator cultivation. The amount of dripping during the whole process cannot be guaranteed to be accurate and consistent. The infection environment is not airtight and there is no disinfection and sterilization measures, so there will be miscellaneous bacteria during the cultivation process. It can not guarantee the accuracy of the follow-up experiments on the cell culture dish after bacterial infection, and it will also cause certain harm to the operator's body, so it cannot meet the growing scientific research and experimental needs in related fields, and hinders the related fields. With the in-depth development of research, in order to fundamentally solve the basic problems of bacterial infection experiments, a device that automatically atomizes and diffuses the drug solution containing bacteria to the cell culture dish exposed to the infection experiment environment for exposure infection experiment equipment R&D has become an inevitable and urgently needed R&D project
