Description

Technical Field

[0001] This application relates to the field of pollution treatment, and more specifically, to a laboratory treatment device for preventing contamination of biological samples. Background Technology

[0002] In daily testing and research activities, laboratories generate a large number of biological samples involving pathogenic microorganisms (such as viruses and bacteria) every day. The common procedure for handling these biological samples after use is as follows: Operators initially collect the samples into dedicated medical waste bins or sharps containers next to the biosafety cabinet or workbench. Once the bins reach a certain capacity, they are sealed, packaged, and transferred to a temporary storage point within the laboratory. Finally, a professional medical waste disposal company handles the centralized collection and harmless treatment. However, if waste bins or bags in the laboratory are not sealed, the pollutants accumulated inside can continuously release into the environment, posing a risk. This is especially true when containers are moved, compressed, or when the internal space changes due to the accumulation of waste, which can easily lead to secondary contamination.

[0018] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0019] It should be noted that the concepts of “one”, “two”, etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0020] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0021] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1: Refer to Figures 1-7 A laboratory processing device for preventing contamination of biological samples includes: a processing shell 11, wherein the processing shell 11 has a plurality of placement cavities 16 distributed circumferentially along the axis of the processing shell 11, the placement cavities 16 having an upper opening, the placement cavities 16 being slidably connected to a storage cylinder 25, the storage cylinder 25 having a storage cavity 26 with an upper opening, the storage cavity 26 being able to hold biological samples, and a sealing mechanism 20 being threadedly connected to the upper end of the processing shell 11, the sealing mechanism 20 being able to seal the upper opening of the storage cavity 26, thereby sealing the biological samples to prevent contamination.

[0023] The sealing mechanism 20 includes a threaded ring 17 threaded to the upper end of the processing shell 11. A plurality of connecting plates 19 passing through the axis of the threaded ring 17 are fixedly connected to the inner side wall of the threaded ring 17. A plurality of cover plates 18 distributed circumferentially along the axis of the threaded ring 17 are fixedly connected to the connecting plates 19. The lower cross-section of the cover plate 18 is larger than the cross-section of the placement cavity 16. When the threaded ring 17 is fixed to the processing shell 11, the axis of the cover plate 18 coincides with the axis of the storage cavity 26, and the lower end face of the cover plate 18 is in close contact with the upper end face of the storage cavity 26, thereby sealing the storage cavity 26 through the cover plate 18.

[0024] A medical-grade thermoplastic elastomer is fixedly connected to the lower end of the cover plate 18. When the lower end surface of the cover plate 18 is in close contact with the upper end surface of the storage cavity 26, the medical-grade thermoplastic elastomer deforms and enters the storage cavity 26, thereby increasing the sealing effect on the upper end of the storage cavity 26.

[0025] The connecting plate 19 is fixedly connected to the same central plate 21. The central plate 21 is threadedly connected to a threaded post 22. A fixing ring 23 is fixedly connected to the lower end of the threaded post 22. A fixing rod 24 is fixedly connected between the fixing ring 23 and the storage cylinder 25.

[0026] The processing shell 11 has a central cavity 14 with an open top. The central cavity 14 is connected to the placement cavity 16 through a connecting groove 15 provided in the processing shell 11. The connecting groove 15 has an open top. The central cavity 14 is slidably connected to the fixing ring 23, and the connecting groove 15 is slidably connected to the fixing rod 24.

[0027] A lever 27 is fixedly connected to the side wall of the threaded ring 17, which allows the user to rotate the threaded ring 17. A first limiting block 12 and a second limiting block 13 are fixedly connected to the side wall of the processing shell 11. When the lever 27 is close to the second limiting block 13, the cover plate 18 seals the storage cavity 26. When the lever 27 is close to the first limiting block 12, the cover plate 18 is offset from the storage cavity 26, allowing biological samples to be placed inside.

[0028] The lower end of the threaded post 22 is threadedly connected to a connecting threaded plate 31. The cross-sectional dimension of the connecting threaded plate 31 is larger than that of the processing shell 11. Through the threaded connection between the connecting threaded plate 31 and the threaded post 22, the threaded post 22 can be fixed to the processing shell 11.

[0029] The outer chamfer of the cover plate 18 is designed to break materials such as cotton swabs that need to be partially broken.

[0030] Example 2: Unlike Example 1, the inner cavity of the threaded ring 17 is not present. In this case, the cover plate 18, the connecting plate 19, and the center plate 21 are all absent. The lower end face of the threaded ring 17 seals the storage cavity 26. A medical-grade thermoplastic elastomer is fixedly connected to the lower end face of the threaded ring 17. The threaded ring 17 is threadedly connected to the threaded post 22.

[0031] Example 3: Unlike Example 1, the storage tube 25 and the fixing rod 24 are detachably connected by a snap fastener.

[0032] Example 4: Unlike Example 1, the storage tube 25 is equipped with an ultraviolet disinfection lamp, which can disinfect biological samples.

[0033] Work or installation process: During installation, the threaded plate 31 and threaded post 22 are separated by threads. The threaded post 22 is inserted into the central cavity 14 and positioned by the sliding connection between the central plate 21 and the central cavity 14 and the sliding connection between the connecting plate 19 and the connecting groove 15. This allows each storage cylinder 25 to slide into the placement cavity 16 and the lever 27 to be in close contact with the side wall of the second limiting block 13. At this time, the threaded plate 31 and the lower end of the threaded post 22 are threaded through the processing shell 11, thereby fixing the threaded post 22 to the processing shell 11 and completing the installation. When biological samples need to be placed after installation, the threaded ring 17 is rotated manually by lever 27, which in turn rotates the connecting plate 19, cover plate 18 and center plate 21. This causes the cover plate 18 to no longer overlap with the storage cylinder 25 in the vertical direction, and the upper opening of the storage cavity 26 is exposed. The biological samples that need to be sealed and preserved can be poured into the storage cavity 26. Different storage cavities 26 can hold different parts of the same batch of biological samples, avoiding cross-contamination between biological samples. When the threaded ring 17 rotates, the lever 27 is limited by the first limiting block 12. After the preservation chamber 26 is filled, the threaded ring 17 is reset by the lever 27, which in turn resets the cover plate 18 to seal the upper end of the preservation chamber 26, thus completing the sealed preservation of the biological sample and avoiding contamination of the biological sample. After storage, the threaded plate 31 is separated from the threaded post 22 by rotating the connecting thread plate 31. Then, the storage cylinder 25 is driven upward away from the processing shell 11 by the lever 27. The storage cylinder 25 containing biological samples can be simply stored. If biological samples need to be stored, they can be easily classified and stored. If biological samples need to be discarded, they can be sealed and thrown into the trash can to avoid contamination from unsealed biological samples. After the shell 11 has been used, it can be sterilized by high-temperature steam and cleaned with cleaning fluid, and then reconnected to a new threaded ring 17 for use.

[0034] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
