Description

Technical Field

[0001] The utility model relates to the technical field of freezing tubes, in particular to a tissue freezing storage tube for a biological sample bank. Background Art

[0002] Cryogenic storage tubes refer to freezing tubes. Cryogenic tubes are experimental tubes made of high-quality polypropylene. They will not deform under high temperature and high pressure sterilization. Cryogenic tubes are mainly used in assisted reproduction or scientific research that requires low-temperature storage of biological samples such as cells or embryos. Therefore, freezing tubes are more important, so the optimization of freezing storage tubes is necessary.

[0003] For example, a new type of freezing storage tube device is disclosed in the Chinese utility model patent with the announcement number CN212650314U. Although the above-mentioned prior art can effectively prevent impurities from entering the tube body during freezing and contaminating the frozen samples in the tube body, when the precious samples are taken out from the storage tube, no matter whether they are taken out with a dropper or directly poured out by tilting, there will be residues of the previous precious liquid on the inner wall of the storage tube. The precious liquid samples are extremely valuable, and even some of the residues are valuable. Therefore, it is necessary to design a biological sample library tissue freezing storage tube that can remove the residual liquid in the storage tube when taking out the precious liquid samples. Utility Model Content

[0004] In order to solve the technical problem that after the precious liquid sample inside the freezing storage tube is taken out, there will still be liquid residue on the inner wall causing waste, the utility model provides a biological sample library tissue freezing storage tube.

[0009] As a further improvement of the above solution, the pushing assembly includes a pushing rod arranged on one side of the storage tube body and a plurality of limit blocks arranged symmetrically at one end of the pushing rod.

[0010] Through the above technical solution, the push rod cooperates with the limit block to push the sealing plate to collect the residual liquid on the inner wall of the storage tube.

[0011] As a further improvement of the above solution, a pushing block is fixedly installed at one end of the pushing rod, and a plurality of clamping blocks are fixedly installed at one side of the storage tube body, and a clamping groove adapted to the pushing rod is provided on one side of the plurality of clamping blocks.

[0016] Through the above technical solution, the fixed plate is installed on the fixed groove so that the scraping plate can scrape and collect the liquid on the sealing plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model arranges an auxiliary component, a pushing component and a scraping component, so that after the precious liquid inside the storage tube is taken out, the scraping component is installed on the storage tube body, and the pushing component pushes the auxiliary component to move and rotate. The movement of the auxiliary component will scrape and collect the residual liquid on the inner wall of the storage tube body, and after moving to fit with the scraping component, the auxiliary component is rotated to transfer the liquid on the auxiliary component to the scraping component, and finally the droplets will be collected along the scraping component.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A biological sample library tissue freezing storage tube of the present embodiment includes a storage tube body 1, one end of the storage tube body 1 is threadedly matched with a storage tube cap 2, the interior of the storage tube body 1 is provided with an auxiliary component for assisting the storage tube body 1 to drain the liquid sample and residue when the precious liquid sample is taken out, one side of the storage tube body 1 is provided with a pushing component for pushing the auxiliary component to move when the precious liquid sample is drained, and the other side of the storage tube body 1 is provided with a scraping component for scraping and collecting the liquid from the auxiliary component after the auxiliary component drains the residual liquid.

[0027] Combination Figure 3 A push hole 6 is provided at one end of the storage tube body 1, and the auxiliary component includes a sealing plate 301 that is slidably sealed inside the storage tube body 1 and a push groove 302 that is provided on one side of the sealing plate 301. The movement of the sealing plate 301 can push and collect the precious liquid remaining on the inner wall of the storage tube body 1.

[0028] Combination Figure 1 and Figure 2The pushing component includes a pushing rod 401 arranged on one side of the storage tube body 1 and a plurality of limit blocks 402 symmetrically arranged at one end of the pushing rod 401. A pushing block 7 is fixedly installed at one end of the pushing rod 401. A plurality of clamping blocks 8 are fixedly installed on one side of the storage tube body 1. A clamping groove matching the pushing rod 401 is provided on one side of the plurality of clamping blocks 8. The pushing rod 401 cooperates with the limit block 402 to push and rotate the sealing plate 301.

[0029] Combination Figure 1 and Figure 4 The scraping assembly includes a scraping plate 501 arranged on one side of the storage tube body 1, a fixing plate 502 fixedly installed on one side of the scraping plate 501, and a lead 503 fixedly installed on one side of the scraping plate 501. A fixing block 9 is fixedly installed on one side of the storage tube body 1, and the fixing plate 502 is arranged in an "L" shape. One side of the scraping plate 501 is arranged in an inclined shape. A jack penetrating the fixing block 9 and matching with the fixing plate 502 is provided on one side of the storage tube body 1. A fixing groove 10 matching with the fixing plate 502 is provided at one end of the storage tube body 1. After the scraping plate 501 scrapes the liquid on the sealing plate 301, the droplets will be guided and collected by the lead 503.

[0030] The implementation principle of a biological sample bank tissue freezing storage tube in the embodiment of the present application is as follows: after the precious liquid inside the storage tube body 1 is taken out, the fixing plate 502 is matched with the fixing groove 10 to install the scraping plate 501 inside the storage tube body 1 and the storage tube body 1 is turned upside down, the pushing rod 401 is removed from the clamping block 8, and one end of the limiting block 402 is inserted into the pushing groove 302 of the sealing plate 301 through the pushing hole 6 and pushed. In this way, the sealing plate 301 will remove the residual liquid on the inner wall of the storage tube body 1 when being pushed. The liquid is scraped onto the sealing plate 301, and the pushing rod 401 is rotated after the sealing plate 301 is pushed to fit with the scraping plate 501. Due to the existence of the limit block 402, the sealing plate 301 will also rotate, thereby scraping the liquid on the sealing plate 301 onto the scraping plate 501. The scraping plate 501 tilted on one side will allow the droplets thereon to flow along the inclined surface and the lead 503, and eventually the droplets are also collected. The waste of droplets can be reduced as much as possible by reducing the size of the scraping plate 501 and the thickness and length of the lead 503.
