Description

Technical Field

[0001] This utility model relates to the field of cell cryopreservation tube technology, specifically a contamination-resistant cell cryopreservation tube. Background Technology

[0002] Cell cryopreservation is a technique that places cells in a low-temperature environment to reduce cellular metabolism for long-term storage. It is one of the main methods of cell preservation, serving the purpose of preserving cell lineage. Cryopreservation involves placing cells in liquid nitrogen at -196°C, temporarily removing them from their growth state while preserving their cellular characteristics. Cell thawing typically uses a rapid thaw method: after removing the cryovial from liquid nitrogen, it is immediately placed in 37°C water to thaw rapidly within one minute, and then the cells are transferred to culture dishes for further cultivation.

[0003] Cryopreservation tubes are a commonly used cryopreservation container for cell transfer. Due to the large temperature differences during freezing and thawing, high requirements are placed on cryopreservation tubes. However, the sealing between the cap and body of existing cell cryopreservation tubes is difficult to guarantee. Sometimes, liquid nitrogen or water can flow into the cell cryopreservation tube from between the cap and the body, which can easily contaminate the sample inside the cell cryopreservation tube.

[0004] Therefore, a contamination-resistant cell cryopreservation tube is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a contamination-proof cell cryopreservation tube, including a test tube holder, a cryopreservation tube, and a capping structure. The cryopreservation tube is placed on the test tube holder, and a test tube cap is provided on top of the cryopreservation tube. The test tube holder includes a mounting base, and multiple support legs are arranged axially on the outside of the mounting base. A support plate is provided below the support legs. The upper two sides of the mounting base are respectively connected to a connecting sleeve by connecting rods. The capping structure includes a threaded sleeve, and multiple inverted L-shaped connecting rods are arranged axially on top of the threaded sleeve. The inverted L-shaped connecting rods are connected to the test tube cap, and an elastic sealing plug is provided at the top inside the test tube cap.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] This invention allows the cryopreservation tube to pass through the through hole of the connecting sleeve and be inserted into the test tube slot on the mounting base, which facilitates the placement of the cryopreservation tube.

[0008] This invention features an external thread on the outside of the cryopreservation tube, which is then threaded to the internal thread inside the threaded sleeve. The tube cap is then placed on the cryopreservation tube, and the elastic seal plug prevents cells from leaking out through the gap between the tube body and the cap, effectively preventing contamination of the sample inside the tube.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] As attached Figure 1-3 As shown, this utility model provides a contamination-resistant cell cryopreservation tube, including a test tube holder, a cryopreservation tube 6, and a capping structure. The cryopreservation tube 6 is placed on the test tube holder, and a test tube cap 9 is provided on top of the cryopreservation tube 6. The test tube holder includes a mounting base 1, and multiple support legs 4 are arranged axially on the outside of the mounting base 1. A support plate 5 is provided below the support legs 4. The upper two sides of the mounting base 1 are respectively connected to a connecting sleeve 3 via connecting rods 2. The capping structure includes a threaded sleeve 7, and multiple inverted L-shaped connecting rods 8 are arranged axially on top of the threaded sleeve 7. The inverted L-shaped connecting rods 8 are connected to the test tube cap 9. An elastic sealing plug 11 is provided at the top inside the test tube cap 9.

[0016] Specifically, the cryopreservation tube 6 passes through the through hole 301 opened on the connecting sleeve 3 and extends to the test tube groove 101 opened at the bottom of the mounting base 1 below the connecting sleeve 3.

[0017] Specifically, a protective pad 10 is provided on the inner sidewall of the through hole 301, which can protect the cryopreservation tube 6.

[0019] Working principle: In use, cells are placed in cryovial 6. Then, the external thread 12 on the top of cryovial 6 is threaded to the internal thread 13 inside the threaded sleeve 7. Then, the test tube cap 9 is placed on cryovial 6, and the elastic sealing plug 11 is placed on the test tube opening of cryovial 6 to prevent cells in cryovial 6 from seeping out through the gap between the tube body and the cap, effectively preventing the sample in the tube from being contaminated. Then, cryovial 6 is inserted through the through hole 301 of the connecting sleeve 3 and into the test tube slot 101 opened on the mounting base 1, which facilitates the placement of cryovial 6.
