Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mesenchymal stem cells, specifically, it relates to a cryopreservation tube for mesenchymal stem cells. Background Technology
[0002] Mesenchymal stem cells are a type of pluripotent stem cell, possessing all the common characteristics of stem cells, namely self-renewal and multiphasic differentiation capabilities. These mesenchymal stem cells are then placed in cryopreservation tubes.
[0003] Patent application CN214758851U discloses a cryopreservation tube for mesenchymal stem cells. Paragraph 0023 of the specification discloses that: a suction cup is provided at the bottom of the tube, and the cryopreservation tube can be fixed on the table by the suction cup, thereby improving the stability when placed.
[0004] However, in practical applications, the bottom of the tube needs to be fixed to the table using a suction cup. Although this can improve the stability when placing the tube, the lack of a guide structure on the top of the suction cup and the bottom of the tube makes it easy for the tube to wobble from side to side when it is attached to the table by the suction cup.
[0005] To address these shortcomings, a cryopreservation tube for mesenchymal stem cells is proposed. Utility Model Content
[0006] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art and provide a cryopreservation tube for mesenchymal stem cells.
[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0008] A cryopreservation tube for mesenchymal stem cells includes a tube body, a cap at the upper opening of the tube body, and a stirring plate that rotates inside the tube body.
[0009] A rotating annular plate is fitted at the bottom of the tube body. One end of the annular plate is threaded with an annular post. One end of the annular post is fixedly fitted with a suction cup. One end of the suction cup is fixedly fitted with a guide rod. One end of the guide rod is movably fitted at the bottom of the tube body.
[0010] Optionally, an inflation tube is connected and communicated on the upper side of the tube cap, and a valve is provided on the outer wall of the inflation tube.
[0011] Optionally, a servo motor is fixedly fitted inside the tube, and a rotating shaft is fixedly fitted at the output end of the servo motor. One end of the stirring blade is fixedly fitted onto one end of the rotating shaft.
[0012] Optionally, a guide hole is provided at the bottom of the tube, and one end of the guide rod is located inside the guide hole.
[0013] Optionally, a first annular groove is provided at the bottom of the tube body, and the annular plate is rotatably fitted inside the first annular groove. The cross-sections of the first annular groove and the annular plate are both T-shaped.
[0014] Optionally, a second annular groove is provided on one side of the annular plate, and the inner wall of the second annular groove is provided with internal threads.
[0015] Optionally, the outer wall of the annular column is provided with an external thread, and the internal thread is threadedly engaged with the external thread.
[0016] Optionally, a plurality of flexible bands are fixedly fitted between the outer wall of the suction cup and the inner wall of the annular column.
[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0018] The guide rod is designed to guide the tube body through the suction cup, reducing the problem of left and right wobbling when the tube body is fixed on the top of the table, making the process of fixing the tube body on the top of the table more convenient and improving the stability of the tube body when placed on the top of the table.
[0019] The first annular groove is designed to allow the annular plate to rotate inside the groove under the action of the annular column. The first annular groove also guides the rotation direction of the annular plate, reducing the problem of the annular plate tilting during rotation and reducing the problem of the annular plate rotating out of the groove, thus improving the stability of the annular plate during rotation.

Detailed Implementation
[0030] The present invention will now be described in further detail with reference to the accompanying drawings.
[0031] Please see Figure 1-4 As shown, this embodiment provides a cryopreservation tube for mesenchymal stem cells, including a tube body 100, a tube cap 101 at the upper opening of the tube body 100, and a stirring plate 105 rotatably fitted inside the tube body 100.
[0032] An annular plate 110 is rotatably fitted at the bottom of the tube body 100. One end of the annular plate 110 is threaded with an annular post 112. One end of the annular post 112 is fixedly fitted with a suction cup 109. One end of the suction cup 109 is fixedly fitted with a guide rod 108. One end of the guide rod 108 is movably fitted at the bottom of the tube body 100.
[0033] Working principle:
[0034] First, mesenchymal stem cells are placed inside the tube 100, and the mesenchymal stem cells inside the tube 100 are stirred by the stirring plate 105. Then, the suction cup 109 is placed at the bottom of the tube 100, and then the annular column 112 is rotated. One end of the annular column 112 rotates to the inside of one end of the annular plate 110. The annular column 112 drives one end of the guide rod 108 to slide into the inside of the tube 100 through the suction cup 109. Then, the tube 100 is fixed to the upper side of the table by the suction cup 109.
[0035] The guide rod 108 is designed to guide the tube 100 via the suction cup 109, reducing the left and right wobbling of the tube 100 when it is fixed on the top of the table. This makes the process of fixing the tube 100 on the top of the table more convenient and improves the stability of the tube 100 when it is placed on the top of the table.
[0036] To make the rotation of the annular plate 110 on one side of the tube body 100 more stable in this embodiment, improvements are made through the following structure, such as... Figure 1-4 As shown, in this embodiment, the upper side of the tube cap 101 is connected to and communicates with an inflation tube 102. The outer wall of the inflation tube 102 is provided with a valve 103. A servo motor is fixedly fitted inside the tube body 100. The output end of the servo motor is fixedly fitted with a rotating shaft 104. One end of the stirring blade 105 is fixedly fitted on one end of the rotating shaft 104. A guide hole 106 is opened at the bottom of the tube body 100. One end of the guide rod 108 is located inside the guide hole 106. A first annular groove 107 is opened at the bottom of the tube body 100. An annular plate 110 is rotatably fitted inside the first annular groove 107. The cross-sections of the first annular groove 107 and the annular plate 110 are both T-shaped. A second annular groove 111 is opened on one side of the annular plate 110. The inner wall of the second annular groove 111 is provided with an internal thread. The outer wall of the annular column 112 is provided with an external thread. The internal thread and the external thread are threadedly fitted. Multiple flexible bands 113 are fixedly fitted between the outer wall of the suction cup 109 and the inner wall of the annular column 112.
[0037] In this embodiment, mesenchymal stem cells are first placed inside the tube 100. Then, the servo motor is started. The output of the servo motor drives the stirring blade 105 to rotate inside the tube 100 via the rotating shaft 104. The stirring blade 105 stirs the mesenchymal stem cells inside the tube 100. Then, the suction cup 109 is placed at the bottom of the tube 100. Then, the annular column 112 is rotated. The annular column 112 is threaded with external and internal threads inside the second annular groove 111. The annular column 112 drives the suction cup 109 to move via the flexible band 113. The suction cup 109 drives one end of the guide rod 108 to slide into the guide hole 106. Then, the suction cup 109 fixes the tube 100 to the upper side of the table, thus completing the fixation of the tube 100.
[0038] The first annular groove 107 is provided so that the annular plate 110 can rotate inside the first annular groove 107 under the action of the annular column 112. The first annular groove 107 guides the rotation direction of the annular plate 110, reduces the problem of the annular plate 110 tilting during rotation, reduces the problem of the annular plate 110 rotating out of the first annular groove 107, and improves the stability of the annular plate 110 during rotation.
