Description

Technical Field

[0001] The utility model relates to the relevant field of mRNA culture medium packaging devices, in particular to an mRNA culture medium packaging device. Background Art

[0002] mRNA exists in the cytoplasm of prokaryotes and eukaryotes and certain organelles of eukaryotic cells. Culture medium refers to a nutrient matrix composed of a combination of different nutrients that is used to provide growth and reproduction for microorganisms, plants or animals (or tissues). It generally contains several major types of substances such as carbohydrates, nitrogen-containing substances, inorganic salts (including trace elements), vitamins and water. Culture medium needs to be packaged during use, so a culture medium packaging device will be used.

[0003] The existing device has the following shortcomings when in use: when packaging the culture medium, it lacks a disinfection and sterilization structure, and cannot ensure packaging in a sterile environment, which easily leads to contamination of the culture medium. The staff needs to reach into the packaging equipment to take and place the culture medium storage tube. The space of the culture medium packaging equipment is limited, which makes it inconvenient for the staff to take and place the culture medium storage tube, affecting the ease of use of the culture medium packaging device. Utility Model Content

[0006] By adopting the above technical solution, after the staff opens the sealed door on the culture medium dispensing box, they use the control button installed on the culture medium dispensing box, which is connected to motor A, and press the move-out button to start motor A to rotate clockwise, so that the ball nut installed on the screw rod moves toward the sealed door, driving the movable plate connected to the ball nut to move, thereby moving the movable plate out of the culture medium dispensing box. The staff places the culture dish placement rack with the dispensing tube into the limit slot on the movable plate, and by pressing the enter button on the control button, starts motor A to rotate counterclockwise, driving the movable plate to move into the culture medium dispensing box, thereby making the movable plate move out of the culture medium dispensing box. The tubes placed on the culture dish placement rack are moved to the culture medium filling box, and the sealed door is closed to fill the culture medium. The culture dish placement rack with the filling tubes inserted is moved by pressing a button. There is no need for the staff to put their hands into the filling equipment to take and place the culture medium storage tubes, which avoids the problem that the culture medium filling equipment is inconvenient for the staff to take and place the culture medium storage tubes due to limited space, and improves the ease of use of the culture medium filling device. By turning on the ultraviolet sterilization lamp installed in the culture medium filling box, the inner cavity of the culture medium filling box can be sterilized, ensuring filling in a sterile environment and reducing the risk of culture contamination.
