[0002] Infectious clinical specimens may contain highly pathogenic viruses, bacteria, or fungi, posing significant biosafety risks during cytological testing. These pathogens not only directly threaten the health of laboratory personnel but can also cause environmental contamination and pathogen transmission. Improper sample storage or handling can easily lead to occupational exposure or pathogen leakage accidents.

[0003] Choosing the right sterilization solution for different infected specimens can effectively inactivate pathogens and maintain the integrity of cell morphology and structure to the greatest extent.

[0004] The current standard testing procedure is as follows: sampling personnel place the sample in a sealed sample bottle for testing. After receiving the sample, the testing department needs to open the sample bottle, add sterilization solution to inactivate the pathogen, and then perform cytological slide preparation. However, at the moment the sample bottle is opened, it is difficult to completely avoid the release of pathogen aerosols or volatile substances, which can contaminate the laboratory environment and pose a high risk of infection to the testing personnel. Summary of the Invention

Detailed Implementation

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] In the description of this utility model, unless otherwise stated, the terms "upper" and "lower" indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0020] like Figures 1 to 5 As shown, the infectious specimen processing and preservation bottle includes a bottle body 1 and a sterile solution reservoir cap. The bottle body 1 is used to store infectious specimens, and the sterile solution reservoir cap is used to store sterile solution.

[0021] The sterilization liquid reservoir cap includes a connecting cylinder 2 and a storage cylinder 3. The connecting cylinder 2 has a cylindrical structure with a drain plate A21 at the bottom, on which two drain ports A22 are provided. The connecting cylinder 2 has an internal thread below the drain plate A21 for connection with the bottle body 1. A sealing film 4 is provided on the lower end face of the drain port A22.

[0022] The storage cylinder 3 is a sealed cylindrical cavity structure, fitted inside the connecting cylinder 2, with its upper section extending out of the connecting cylinder 2. The bottom of the storage cylinder 3 is equipped with a drain plate B31, on which two drain ports B32 are formed. A sealing membrane 4 is provided on the lower end face of each drain port B32. After rotating between the storage cylinder 3 and the connecting cylinder 2, the drain ports A22 and B32 can be aligned vertically.

[0023] A needle-piercing assembly 23 is fixed inside the leak port A22, and the needle-piercing assembly 23 is located above the sealing membrane 4. The function of the needle-piercing assembly 23 is to simultaneously pierce the sealing membrane 4 of both the leak port A22 and the leak port B32 when the storage cylinder 3 moves downward. Any structure that can achieve this function is acceptable. As one optional solution, the needle-piercing assembly 23 includes a fixed circular plate 25 and elastic rods 26 radially distributed around the outer periphery of the fixed circular plate 25. The elastic rods 26 are arranged in two rows, and the outer ends of the elastic rods 26 are fixed to the inner wall of the leak port A22. The upper and lower end surfaces of the fixed circular plate 25 are provided with needles 27. When the storage cylinder 3 moves downward, the needles 27 located below pierce the sealing membrane of the leak port A22, and the needles 27 located above pierce the sealing membrane of the leak port B32. The elastic rod 26 is made of elastic plastic and has a certain degree of elasticity. When the needle 27 located above is pressed down by the sealing membrane on the leakage port B32, it can be pressed down, causing the needle 27 located below to move down and puncture the sealing membrane.

[0024] The storage container 3 includes a container body 24 and a sealing cap 25 located at the upper end of the container body 24. The sealing cap 25 can be threaded to the container body 24 or integrally machined. The threaded connection makes it easier to open the sealing cap 25 to disinfect the container after use and also makes it easier to fill with sterilizing solution.

[0025] To ensure the specimen inside bottle 1 remains well-sealed, a grooved ring A11 is provided on the upper surface of the bottle opening, and a sealing ring A24 is provided on the lower surface of the leakage plate A21 to seal against the grooved ring A11. Simultaneously, a grooved ring B28 is provided on the upper surface of the leakage plate A21, and a sealing ring B33 is provided on the lower surface of the leakage plate B31 to seal against the grooved ring B. Before releasing the sterilizing solution, the grooved ring A11 and sealing ring A24 are sealed together to prevent leakage of the sample inside bottle 1. When releasing the sterilizing solution, the storage cylinder 3 is pressed down, and as the needle piercing assembly 23 simultaneously punctures the sealing membrane 4 of the leakage outlets A22 and B32, the grooved ring B28 and sealing ring B33 seal together, ensuring the seal of the sample inside bottle 1.

[0026] Preferably, both the connecting cylinder 2 and the sterilization liquid reservoir cap are made of transparent material, and the cylinder 24 is marked with graduations. Normally, the amount of sterilization liquid added needs to be adjusted according to the sample situation. The transparent material and graduations make it easy to observe the amount of sterilization liquid added.

[0027] It should be noted that, in order to ensure that the needle 27 does not puncture the sealing membrane 4 before the sterilizing liquid is released, a certain space needs to be maintained between the storage cylinder 3 and the leakage plate A21. For this purpose, a tear ring 5 is provided between the sealing cap 25 and the connecting cylinder 2. The height of the tear ring 5 is such that the needle 27 can avoid contact with the sealing membrane 4 before the sterilizing liquid is released. At the same time, when the sterilizing liquid needs to be released, it is advisable to provide sufficient downward displacement for the storage cylinder 3 so that the needle 27 can puncture the sealing membrane 4 of the leakage port A22 and the leakage port B32 respectively. Example 2

[0028] This embodiment optimizes the needle puncture structure based on Embodiment 1.

[0029] It should be noted that under normal circumstances, the sterilization solution in the storage cylinder 3 will not be full, and there is air above the sterilization solution. Even in a sealed state, the sterilization solution in the storage cylinder 3 can enter the bottle 1 after the sealing membrane 4 is punctured. After the sealing membrane 4 is punctured, the bottle 1 and the storage cylinder 3 are connected by air, and the pressure inside the storage cylinder 3 and the bottle 1 is balanced, so the sterilization solution can continuously enter the bottle 1.

[0030] In order to increase the tear opening of the sealing film 4 and accelerate the flow of sterilization liquid into the bottle 1, this embodiment provides an umbrella-shaped tear bar 29 at the end of the needle 27. By adding the umbrella-shaped tear bar 29, the tear opening of the sealing film 4 can be increased.

[0031] The working process of this utility model: The sterilization solution reservoir cap containing the sterilization solution is placed on the bottle body 1. After the cap is closed, the leak plate A21 and the bottle body 1 are aligned at the bottle opening, and the sealing ring A24 and the sealing groove A11 are locked together. When it is necessary to put the sterilization solution into the bottle body 1, the tear ring 5 is removed and the sterilization solution reservoir cap is pressed down. When pressed down, the needles 27 of the needle-punching assembly 23 puncture the sealing membranes 4 on the leak outlets A22 and B32 respectively. The sterilization solution flows into the bottle body from the sterilization solution reservoir cap. To ensure smooth flow, after the needles 27 puncture the sealing membranes 4, the cylinder 24 can be rotated to widen the gap between the needles 27 and the punctures of the sealing membranes 4. During this process, even if the sterilization solution enters between the leak plates A21 and B31, it will not significantly affect the release of the sterilization solution.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
