Description

Technical Field

[0001] This utility model relates to the field of cryopreservation tube technology, specifically to a cryopreservation tube for laboratory testing. Background Technology

[0002] In the fields of biomedical research and clinical testing, cryovials for laboratory testing are key consumables used for the collection, storage and transportation of biological samples (such as blood, tissues, cells, DNA / RNA, etc.). Samples usually need to be preserved in a low-temperature environment for a long time to maintain their biological activity and stability. Cryovials are mostly made of polypropylene and are often used in conjunction with cryovial boxes to facilitate the orderly storage of samples.

[0003] Existing cryopreservation tubes for laboratory testing are prone to deformation or loosening of the cap during repeated freeze-thaw cycles or long-term low-temperature storage. This can lead to sample leakage or evaporation, resulting in sample loss or cross-contamination. Therefore, it is necessary to provide a cryopreservation tube for laboratory testing that solves the above-mentioned technical problems. Utility Model Content

[0004] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a new type of cryopreservation tube for laboratory testing is proposed. This addresses the problem that the cap on the top of the cryopreservation tube is prone to deformation or loosening during repeated freeze-thaw cycles or long-term low-temperature storage, which can lead to sample leakage or evaporation, resulting in sample loss or cross-contamination.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a cryopreservation tube for laboratory testing, including a cryopreservation tube body for laboratory testing. The top of the cryopreservation tube body is provided with a cap mechanism for sealing. The bottom of the cryopreservation tube body is fixedly provided with a base. A plurality of protective side support plates are evenly fixedly provided around the top of the base. The plurality of protective side support plates are evenly distributed around the outside of the cryopreservation tube body. The upper parts of two adjacent protective side support plates are fixedly connected by a horizontal connecting arc plate.

[0006] Furthermore, the cover mechanism includes an outer sealing cover, which is threaded onto the top of the cryopreservation tube. An inner sealing plug is fixedly installed at the top of the inner cavity of the outer sealing cover, and the inner sealing plug is made of a soft material.

[0007] Furthermore, the inner sealing plug extends through the top of the inner cavity of the cryopreservation tube, and the sidewall of the inner sealing plug contacts the inner wall of the cryopreservation tube.

[0008] Furthermore, a conical hole is provided between the top of the inner sealing plug and the outer sealing plug, and a conical external thread plug is passed through the internal thread of the conical hole.

[0009] Furthermore, a screwing block is fixedly provided on the top of the conical external thread plug, and several first sealing rings are evenly arranged from top to bottom between the inner cavity sidewalls of the outer sealing cover.

[0010] Furthermore, the outer surface of the inner sealing plug is uniformly fitted with several second sealing rings from top to bottom.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: Through the cooperation between the cover mechanism, base, protective side support plate and horizontal connecting arc plate, the cover mechanism at the top of the cryopreservation tube is not prone to deformation or loosening during repeated freeze-thaw cycles or long-term low-temperature storage, which can effectively prevent sample leakage or evaporation in the cryopreservation tube and prevent sample loss or cross-contamination. The base, protective side support plate and horizontal connecting arc plate can constrain the shape of the cryopreservation tube, effectively avoiding the risk of tube bursting. Through the cooperation between the outer sealing cover, inner sealing plug and conical external thread plug, the top of the cryopreservation tube can achieve a multi-seal effect. The setting of the first sealing ring and the second sealing ring further enhances the sealing effect on the top of the cryopreservation tube. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] A cryopreservation tube for laboratory testing includes a cryopreservation tube body 1 for laboratory testing. The top of the cryopreservation tube body 1 is provided with a cap mechanism 2 for sealing. The bottom of the cryopreservation tube body 1 is fixedly provided with a base 3. Several protective side support plates 4 are evenly fixedly provided around the top of the base 3. The protective side support plates 4 are evenly distributed around the outside of the cryopreservation tube body 1. The upper parts of two adjacent protective side support plates 4 are fixedly connected by a horizontal connecting arc plate 5. Through the cooperation between the cap mechanism 2, the base 3, the protective side support plates 4 and the horizontal connecting arc plate 5, the cap mechanism 2 at the top of the cryopreservation tube body 1 is not prone to deformation or loosening during repeated freeze-thaw cycles or long-term low-temperature storage. This can effectively prevent the sample inside the cryopreservation tube body 1 from leaking or evaporating, and prevent sample loss or cross-contamination. The base 3, the protective side support plates 4 and the horizontal connecting arc plate 5 can constrain the shape of the cryopreservation tube body 1, effectively avoiding the risk of the cryopreservation tube body 1 bursting.

[0016] In this embodiment, the cover mechanism 2 includes an outer sealing cover 21, which is threaded onto the top of the cryopreservation tube 1. An inner sealing plug 22 is fixedly installed on the top of the inner cavity of the outer sealing cover 21, and the inner sealing plug 22 is made of soft material.

[0017] In this embodiment, the inner sealing plug 22 extends through the top of the inner cavity of the cryopreservation tube 1, and the side wall of the inner sealing plug 22 is in contact with the inner wall of the cryopreservation tube 1.

[0018] In this embodiment, a conical hole is provided between the top of the inner sealing plug 22 and the outer sealing cover 21, and a conical external thread plug 23 passes through the internal thread of the conical hole.

[0019] In this embodiment, a screwing block 24 is fixedly provided on the top of the tapered external thread plug 23, and a plurality of first sealing rings 25 are uniformly arranged from top to bottom between the inner cavity sidewalls of the outer sealing cover 21.

[0020] In this embodiment, a plurality of second sealing rings 26 are uniformly fitted on the outside of the inner sealing plug 22 from top to bottom. Through the cooperation between the outer sealing cover 21, the inner sealing plug 22 and the conical external thread plug 23, a multi-seal effect can be achieved on the top of the cryopreservation tube 1. The setting of the first sealing ring 25 and the second sealing ring 26 further enhances the sealing effect on the top of the cryopreservation tube 1.

[0021] Working principle: In use, the outer sealing cap 21 is screwed onto the top outer wall of the cryopreservation tube body 1, while the inner sealing plug 22 simultaneously penetrates the top of the inner cavity of the cryopreservation tube body 1. The first sealing ring 25 is in close contact with the outer wall of the cryopreservation tube body 1, and the second sealing ring 26 is in close contact with the inner wall of the cryopreservation tube body 1. Then, the conical external thread plug 23 is screwed downwards into the conical hole. During the process of the conical external thread plug 23 being screwed into the conical hole, the inner sealing plug 22 is squeezed by the conical external thread plug 23, making the inner sealing plug 22 contact the inner wall of the cryopreservation tube body 1 more tightly. The first sealing ring 25 and the second sealing ring 26 are in close contact. The sealing ring 26 further enhances the sealing effect on the top of the cryopreservation tube 1, ultimately achieving a multi-layered sealing effect on the top of the cryopreservation tube 1. Then, the sealed cryopreservation tube containing the sample is placed in a designated low-temperature environment. During repeated freeze-thaw cycles or long-term low-temperature storage, the cap mechanism 2 at the top of the cryopreservation tube 1 is not prone to deformation or loosening, effectively preventing sample leakage or evaporation inside the cryopreservation tube 1, and preventing sample loss or cross-contamination. The base 3, protective side support plate 4, and horizontal connecting arc plate 5 can constrain the shape of the cryopreservation tube 1, avoiding the risk of the cryopreservation tube 1 bursting.
