Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a stem cell detection sample storage device. Background Technology

[0002] Stem cells are a type of pluripotent cell with the ability to self-renew. Under certain conditions, they can differentiate into various functional cells. Based on their developmental stage, stem cells are classified into embryonic stem cells and adult stem cells. Based on their developmental potential, they are classified into three categories: totipotent stem cells, multipotent stem cells, and unipotent stem cells (differentiated stem cells). Stem cells are undifferentiated, immature cells with the potential to regenerate various tissues, organs, and the human body; they are known in the medical field as "universal cells." Scientific research on stem cells requires cryopreservation of sampled stem cells, necessitating the use of cold storage containers in the laboratory.

[0003] Chinese utility model CN202120605509.4 describes a sample storage box for stem cell testing, which is designed with a convenient storage device. The principle is that an electric telescopic rod is installed inside the placement chamber. The test tube is pushed upward from inside the placement chamber by the electric telescopic rod, so that the top of the test tube is exposed for easy retrieval.

[0004] However, existing devices require turning a bolt to separate the cap from the chamber when retrieving the test tubes, then removing the cap before taking the test tubes out. This leads to cold air leakage inside the chamber, affecting stem cell storage, and the need to remove the bolt each time is cumbersome. Therefore, a sample storage device was designed to address the above-mentioned problems. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] In related technologies, the principle involves installing an electrically operated telescopic rod inside the placement chamber. This rod pushes the test tube upwards from the chamber, exposing its top for easy retrieval. However, existing devices require turning bolts to separate the cap from the chamber before removing the test tube. This leads to cold air leakage inside the chamber, affecting stem cell storage, and the need to remove the bolts each time is cumbersome.

[0032] To address some of the problems in related technologies, this application provides a stem cell testing sample storage device. When a stem cell sample tube to be tested is removed, firstly, the sealing plate at the top of the lid 12 is rotated to expose the groove on the lid 12. Then, a finger is inserted through the groove on the lid 12 into the inside of the riser tube 13 to press the tube, causing it to move downwards inside the riser tube 13. Simultaneously, the base plate 21 is pushed downwards, causing the base plate 21 to push the riser plate 22 to move accordingly. At this time, the protrusion 26 at one end of the riser 25 slides inside the guide groove 23, while the spring 24 rebounds and pushes the riser plate 22 upwards, causing the protrusion 26 to slide to the bottom of the guide groove 23. During the upward movement of the riser plate 22, the base plate 21 is pushed, causing the top of the tube to protrude from the top of the riser tube 13 for easy removal. When it is necessary to insert the test tube into the riser 13, simply insert the bottom into the riser 13 and press down, while simultaneously pushing the riser plate 22 downwards. This allows the protrusion 26 to slide inside the guide groove 23 until it reaches the top of the guide groove 23. After releasing the test tube, the spring 24 rebounds and pushes the riser plate 22 upwards, causing the protrusion 26 to stop at the arc-shaped part at the top of the guide groove 23. Then, rotate the sealing plate on the cap 12 to seal it.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] This application provides a stem cell detection sample storage device, comprising: a box 11 with a lid 12 rotatably mounted on its top; a riser 13 disposed inside the box 11; and a spring-loaded assembly 2 disposed inside the riser 13, the spring-loaded assembly 2 comprising: a base plate 21 disposed inside the riser 13; a riser plate 22 disposed at the bottom of the base plate 21; a guide groove 23 formed on the outer side wall of the riser plate 22; a spring 24 disposed at the bottom of the riser plate 22 and connected at its bottom end to the bottom of the riser 13; a riser 25 rotatably disposed on the inner side wall of the bottom end of the riser 13; and a protruding rod 26 disposed at the top end of the riser 25 and inserted into the guide groove 23.

[0035] When taking out the stem cell sample tube to be tested, first rotate the sealing plate on the top of the cap 12 to expose the groove on the cap 12. Then, insert your finger through the groove on the cap 12 into the inside of the riser tube 13 and press the tube down, causing the tube to move downward inside the riser tube 13. At the same time, this pushes the base plate 21 downward, causing the base plate 21 to push the riser plate 22 to move accordingly. At this time, the protrusion 26 at one end of the riser 25 slides inside the guide groove 23, while the spring 24 rebounds and pushes the riser plate 22 upward, causing the protrusion 26 to slide to the bottom of the guide groove 23. As the riser plate 22 moves upward, it pushes the base plate 21, causing the top of the tube to protrude from the top of the riser tube 13 for easy removal. When it is necessary to insert the test tube into the riser 13, simply insert the bottom into the riser 13 and press down, while simultaneously pushing the riser plate 22 downwards. This allows the protrusion 26 to slide inside the guide groove 23 until it reaches the top of the guide groove 23. After releasing the test tube, the spring 24 rebounds and pushes the riser plate 22 upwards, causing the protrusion 26 to stop at the arc-shaped part at the top of the guide groove 23. Then, rotate the sealing plate on the cap 12 to seal it.

[0036] In some embodiments, the outer sidewall of the base plate 21 is fitted with the inner sidewall of the riser 13.

[0037] The design that fits snugly during use makes it more stable when moving up and down, preventing wobbling and maintaining the stability of the base plate 21.

[0038] In some embodiments, the guide groove 23, the upright 25, and the protruding rod 26 are symmetrically arranged in two sets.

[0039] The design with two sets of settings can make the restriction effect better.

[0040] In some embodiments, the rebound assembly 2 further includes a rubber pad 27 disposed on the top of the protrusion 26.

[0041] The rubber pad 27 is designed to cushion the impact when the base plate 21 contacts the bottom of the test tube.

[0042] In some embodiments, the rebound assembly 2 further includes a rubber block 28 disposed on the inner sidewall of the riser 13.

[0043] When in use, the design of the rubber block 28 allows the test tube to be inserted into the riser 13 and clamped to keep the test tube in a vertical position.

[0044] In some embodiments, the rebound assembly 2 further includes a partition 29 disposed inside the housing 11 and penetrated by the riser 13.

[0045] The design of the partition 29 can better isolate the temperature inside the chamber 11, thus preventing the stem cells inside the test tube from being contaminated.

[0046] In some embodiments, the spring-loaded assembly 2 further includes a protrusion 291 disposed on the outer side wall of the cover 12.

[0047] The design of the protrusion 291 during use increases friction when rotating the cover 12.

[0048] In some embodiments, a positioning component 3 is provided at the bottom of the cover 12. The positioning component 3 further includes: a tube 31 disposed at the top of the partition 29; a through groove 32 opened on the inner side wall of the tube 31 corresponding to the position of the riser 13; a cylinder 33 disposed at the bottom of the cover 12; a groove 34 opened on the outer side wall of the cylinder 33; a second spring 35 disposed inside the groove 34; and an arc-shaped block 36 with one end inserted into the inside of the groove 34 and connected to the second spring 35.

[0049] When in use, rotating the cover 12 will cause the cylinder 33 to rotate inside the tube 31 until the groove 34 is aligned with the through groove 32. Then, the spring 35 will rebound and push one end of the arc block 36 into the inside of the through groove 32. Because the through groove 32 corresponds to the position of the riser 13, when the arc block 36 is engaged with the through groove 32, the groove at the top of the cover 12 will be aligned with the riser 13.
