Description

Technical Field

[0001] This utility model relates to the field of microbial culture technology, specifically a base plate suitable for microbial sample pretreatment inoculation and culture modules. Background Technology

[0002] Microbial sample pretreatment is a core step in microbial instrumental analysis. This process involves decomposing microbial samples to quantitatively dissolve target components. It must adhere to five principles, including avoiding chemical changes and preventing contamination. It mainly addresses the purification and enrichment of complex matrix samples (including proteins, oils, etc.).

[0003] When using a base plate for microbial sample pretreatment, inoculation, and culture, a directional locking cap is typically used to reduce moisture loss during long-term culture. However, the cap is usually a single piece that can only cover all culture wells at a time. When sampling is needed for a few culture wells, the cap must be opened, thus opening all culture wells. During sampling, the samples in the remaining culture wells may be contaminated or lose moisture. Therefore, a base plate suitable for microbial sample pretreatment, inoculation, and culture modules needs to be designed to improve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a base plate suitable for microbial sample pretreatment inoculation and culture modules.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0015] In the following description, embodiments of the base plate of the present invention, applicable to the microbial sample pretreatment inoculation and culture module, will be described with reference to the accompanying drawings.

[0016] Figure 1-4 This invention illustrates a base plate for a microbial sample pretreatment inoculation and culture module according to an embodiment of the present invention, comprising: A culture base plate 1 has N culture holes 2 on its top, each with a flat, round, or V-shaped bottom. These culture holes 2 are arranged in a rectangular array on the top of the culture base plate 1. A cover 3 is detachably mounted on the top of the culture base plate 1. Specifically, grooves 7 are provided on both sides of the cover 3, and the inner cavity of each groove 7 has anti-slip grooves. The grooves 7 and anti-slip protrusions 10 work together to facilitate the user's handling of the cover 3 and the culture base plate 1. N mounting slots 5 are provided on the top of the inner cavity of the cover 3, arranged in a rectangular array. The inner cavity of the body 3 has a corresponding mounting groove 5 and a culture hole 2. The top of the cover body 3 has N round holes 4, which are located at the top of the inner cavity of the mounting groove 5. The round holes 4 can correspond one-to-one with the culture holes 2, making it easy for users to identify them. They can also limit the upward rotation of the rotating door 61. The inner cavity of the mounting groove 5 is equipped with a sealing door assembly 6. Specifically, the sealing door assembly 6 includes rotating doors 61 that are rotatably connected to the left and right sides of the inner cavity of the mounting groove 5 by torsion springs. Flexible sealing strips 62 are glued to the opposite ends of the rotating doors 61. Where N is 6, 12, 24, 48 or 96, to meet diverse testing requirements; Specifically, protruding posts 8 are glued to the four corners of the top of the culture base plate 1. By setting the protruding posts 8, after the cover body 3 is installed, the distance between the sealing door assembly 6 and the inner cavity of the culture hole 2 can be increased, so as to avoid the rotating door 61 coming into contact with the culture medium in the culture hole 2 when the sealing door assembly 6 rotates to open the inner cavity of the culture hole 2, thus preventing contamination. Specifically, the bottom of the culture base plate 1 is provided with a base plate 9, the height of which is 8-11 mm. The surface of the base plate 9 is provided with anti-slip raised strips 10. By setting the base plate 9, the bottom edge of the culture base plate 1 is raised to prevent cross-contamination. Specifically, identification codes 11 are set on the front and left sides of the top of the culture base plate 1. The culture wells 2 are numbered by combining the identification codes 11. By setting the identification codes 11, the numbers and letters in the codes 11 can be identified in the horizontal and vertical directions to number each culture well 2, which makes it easy for users to quickly identify the culture wells 2. Among them, the cultivation base plate 1, cover 3, rotating door 61, protruding column 8, base plate 9, anti-slip protrusion 10 and identification code 11 are all made of highly transparent polystyrene material; When using this culture base plate, the operation will be carried out on the sterilization table, and the opening and closing of the rotating door 61 will not introduce other bacteria and cause contamination.

[0017] Working principle: When using this utility model, the user places the cover 3 on top of the culture base plate 1. When sampling is required, the sampling tube is aligned with the round hole 4 and inserted downwards into the inner cavity of the culture well 2. At this time, the rotating door 61 is forced to rotate downwards to open the inner cavity of the mounting groove 5 and compress the torsion spring on the surface of the rotating door 61, thereby facilitating the sampling tube to sample the microorganisms in the inner cavity of the culture well 2. When the sampling is finished and the sampling tube is removed, the rebound force of the torsion spring drives the rotating door 61 to automatically reset. Since each sealing door component 6 is independent of each other and does not interfere with each other, when sampling one or several culture wells 2, the remaining culture wells 2 do not affect each other.

[0018] In summary, this base plate, suitable for microbial sample pretreatment inoculation and culture modules, achieves individual sealing of the culture wells 2 in the culture base plate 1 through the sealing door component 6 in the cover 3, thereby facilitating the user to perform sampling operations on any culture well 2 without affecting each other.

[0019] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
