AI Technical Summary
Existing Helicobacter pylori culture dishes are not easy to operate with one hand when opening and closing the sealing cap, and each time they need to be fully opened, which can easily lead to a large area of culture medium being exposed, affecting the culture quality.
Design a porous Helicobacter pylori culture dish with a rotating mounting mechanism inside the outer shell. The culture dish has multiple culture loops, and the outer shell has a semi-circular cover and a flexible arc cover. The covers are connected by folds, allowing each culture loop to be opened and closed individually, avoiding full-coverage operation.
This allows for one-handed operation of the culture dish, avoiding large-area exposure of the culture medium and ensuring the uniformity and quality of the culture.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a Helicobacter pylori culture dish with a porous design. Background Technology
[0002] Helicobacter pylori (HP) is a microaerophilic bacterium that lives in the mucous membrane of the human stomach. It is also the only microorganism found in the human stomach to date.
[0003] To identify Helicobacter pylori, it is necessary to culture it in appropriate petri dishes. However, existing petri dishes are not convenient for users to operate with one hand when opening and closing the sealed lid, and each time they need to be fully opened, which can easily lead to unnecessary exposure.
[0004] Therefore, it is essential to invent a Helicobacter pylori culture dish with a porous design. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a Helicobacter pylori culture dish with a porous design. The technical solution is as follows: A Helicobacter pylori culture dish with a porous design includes a shell and a culture dish, wherein: the culture dish is rotatably installed inside the shell, and several culture ring cavities of different diameters are coaxially opened on the culture dish; a semi-circular cover plate is coaxially fixedly installed on one side of the upper part of the shell, and the radius of the semi-circular cover plate is the same as the radius of the shell; several arc-shaped cover plates corresponding to the culture ring cavities are flexibly installed coaxially on one side of the semi-circular cover plate; creases are provided at the connection between the arc-shaped cover plates and the semi-circular cover plates; the culture dish is located below the semi-circular cover plates and the arc-shaped cover plates; and the culture dish is rotatably connected to the semi-circular cover plates and the arc-shaped cover plates.
[0006] Preferably, the upper surface of the outer shell has a coaxially formed upward-facing circular cavity, the depth of which is the same as the thickness of the culture dish, the culture dish is rotatably installed in the circular cavity, and the semi-circular cover plate is coaxially fixedly installed on one side of the opening of the circular cavity.
[0007] Preferably, a gap is provided between each of the arc-shaped cover plates.
[0008] Preferably, each of the arc-shaped cover plates has an integral sealing protrusion on the side that contacts the culture ring cavity, and the width of the arc-shaped cover plate is greater than the width of the corresponding culture ring cavity.
[0009] Compared with the prior art, the advantages of this utility model are:
[0010] 1. The overall design of this utility model not only enables the classification and culture of Helicobacter pylori through a single culture dish, but also ensures the uniformity of the culture medium in the culture loop cavity, thus improving the culture of Helicobacter pylori.
[0011] 2. The overall design of this utility model not only prevents the sealing cap from separating from the culture dish during use, but also allows for the implantation and collection of Helicobacter pylori without fully opening the sealing cap. This facilitates opening and closing with one hand and avoids large-area exposure to air, ensuring culture quality. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: Example
[0021] Reference Figure 1-4 A porous Helicobacter pylori culture dish includes a shell 1 and a culture dish 2. The culture dish 2 is rotatably mounted inside the shell 1. During sample inoculation, rotating the shell 1 allows the opening of the circular cavity 8 to rotate along the culture dish 2, thus evenly spreading the sample into the corresponding culture loop cavity 3. The culture dish 2 has several coaxially formed culture loop cavities 3 of different diameters for the classification and culture of Helicobacter pylori. A semi-circular cover plate 4 is coaxially fixed to one side of the upper part of the shell 1. This semi-circular cover plate 4 always covers half of the area of each culture loop cavity 3, reducing the exposure of the culture medium and sample to air. The radius of the semi-circular cover plate 4 is the same as that of the shell 1. With the same radius, several arc-shaped cover plates 5 corresponding to the culture loop cavity 3 are flexibly installed coaxially on one side of the semi-circular cover plate 4. This allows the individual corresponding culture loop cavity 3 to be sealed by the arc-shaped cover plate 5, while also facilitating the opening of one culture loop cavity 3 for corresponding operations. A crease 9 is provided at the connection between the arc-shaped cover plate 5 and the semi-circular cover plate 4. The crease 9 allows the arc-shaped cover plate 5 to be flipped to one side of the semi-circular cover plate 4, so that the culture loop cavity 3 is exposed from the opening of the circular cavity 8. The culture dish 2 is located below the semi-circular cover plate 4 and the arc-shaped cover plate 5. The culture dish 2 is rotatably connected to the semi-circular cover plate 4 and the arc-shaped cover plate 5 to collect colonies at different locations inside the culture loop cavity 3.
[0022] In this embodiment, the upper surface of the outer shell 1 is coaxially provided with an upward-facing circular cavity 8 to provide installation space for the petri dish 2 and to ensure the stability between the petri dish 2 and the outer shell 1 as well as the smoothness of rotation. The depth of the circular cavity 8 is the same as the thickness of the petri dish 2. The petri dish 2 is rotatably installed in the circular cavity 8, and the semi-circular cover plate 4 is coaxially fixedly installed on one side of the opening of the circular cavity 8.
[0023] In this embodiment, a gap 6 is provided between each arc-shaped cover plate 5 so that the arc-shaped cover plate 5 can be opened and closed individually through the gap 6.
[0024] In this embodiment, each arc-shaped cover plate 5 is provided with an integral sealing protrusion 7 on the side that contacts the culture ring cavity 3, so as to seal the culture ring cavity 3 through the sealing protrusion 7. The width of the arc-shaped cover plate 5 is greater than the width of the corresponding culture ring cavity 3.
[0025] Specifically, when planting the sample, first open one of the arc-shaped cover plates 5 corresponding to the culture ring cavity 3, so that the culture ring cavity 3 is exposed from the opening of the circular cavity 8. At this time, rotate the outer shell 1 so that the culture medium is evenly placed in the culture ring cavity 3. Then, operate on the other culture ring cavities 3 in the same way.
[0026] When placing the sample, similarly, first open one of the arc-shaped cover plates 5 corresponding to the culture ring cavity 3, so that the culture ring cavity 3 is exposed from the opening of the circular cavity 8. At this time, rotate the outer shell 1 to evenly spread the sample in the culture ring cavity 3. Then, operate on the other culture ring cavities 3 in the same way.
[0027] The same procedure can be followed for subsequent sampling.
[0028] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
