Description

Technical Field

[0001] This utility model belongs to the field of cell cryopreservation technology, and in particular relates to a test tube support frame for cell cryopreservation. Background Technology

[0002] Cell cryopreservation is a technique that preserves cells by placing them in a low-temperature environment. Its main purpose is to extend cell survival time by reducing cellular metabolic activity and slowing down cell growth, reproduction, and aging processes, so that viable cells can be used when needed. Cell cryopreservation technology has wide applications in medicine, biology, and other fields, such as preserving stem cells, immune cells, and tumor cells for cell therapy, drug development, and cell biology research.

[0003] The test tube support racks used for cell refrigeration employ support rods and test tube clamps for fixation. Their stability depends on the clamping force of the test tube clamps, and the lack of a supporting structure at the bottom limits their stability. Furthermore, when arranging test tubes in batches, a large number of test tube clamps are required for fixation, which is time-consuming, cumbersome, and results in disordered arrangement. Therefore, there is a need for a test tube support rack for cell refrigeration that uses a rotating support structure to arrange and fix test tubes in an orderly manner. This facilitates the selection of specific test tubes by the user and improves the stability during storage. Utility Model Content

[0022] In the following description, embodiments of the cell refrigeration test tube support of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a cell refrigeration test tube support frame according to an embodiment of the present invention, comprising a support base 1. The inner cavity of the support base 1 is provided with an upper support frame 2 and a lower support frame 3. The top of the upper support frame 2 has a plurality of insertion holes 4 adapted to the test tubes in a ring shape. The top of the lower support frame 3 has a plurality of positioning holes 5 adapted to the test tubes in a ring shape. A plurality of rubber pads 7 are distributed in a ring shape within the inner cavity of the positioning holes 5. The rubber pads 7 are fixedly connected to the inner wall of the positioning holes 5. The rubber pads 7 allow the inner cavity of the positioning holes 5 to elastically contact the surface of the test tube, providing elastic support and enabling the test tubes to be stably inserted into the inner cavities of the insertion holes 4 and positioning holes 5, thereby improving the stability of the test tubes after placement. A docking assembly 6 is provided between the upper support frame 2 and the lower support frame 3. The docking assembly 6 includes a rotating head 61 rotatably connected to the top of the upper support frame 2. The bottom of the rotating head 61 extends through to the bottom of the upper support frame 2 and is fixedly connected with a threaded head 62. The lower support... A threaded sleeve 63 is fixedly connected to the top of the frame 3, and a threaded head 62 is threaded into the inner cavity of the threaded sleeve 63. A rotating column 64 is fixedly connected to the bottom of the lower support frame 3. A positioning tube 65 is fixedly connected to the center of the bottom of the inner cavity of the support base 1. The rotating column 64 is rotatably connected to the inner cavity of the positioning tube 65. Multiple ventilation holes 8 are circumferentially opened on the surface of the support base 1. The ventilation holes 8 are connected to the inner cavity of the support base 1. A water-absorbing pad 9, which is a sponge pad, is placed at the bottom of the inner cavity of the support base 1. Multiple plugs 10 are circumferentially distributed at the bottom of the upper support frame 2 and fixedly connected thereto. Multiple insertion tubes 11 are circumferentially distributed at the top of the lower support frame 3 and fixedly connected thereto. The plugs 10 are inserted into the inner cavity of the insertion tubes 11. Through the cooperation of the plugs 10 and the insertion tubes 11, the upper support frame 2 and the lower support frame 3 can be docked and stacked, thereby making the upper support frame 2 and the lower support frame 3 stably connected and improving the stability of the upper support frame 2 and the lower support frame 3 after stacking.

[0024] Working principle: When using this invention, the user places the upper support frame 2 on top of the lower support frame 3, allowing the plug 10 to enter the inner cavity of the insertion tube 11. Simultaneously, the user rotates the rotating head 61, causing the threaded head 62 to rotate and enter the inner cavity of the threaded sleeve 63. This continues until the rotating head 61 can no longer rotate. At this point, the upper support frame 2 and the lower support frame 3 are connected and fixed by the threaded head 62 and the threaded sleeve 63, and the plug 10 is fully inserted into the inner cavity of the insertion tube 11. Then, the upper support frame 2 and the lower support frame... 3 is placed in the inner cavity of the support base 1, while the rotating column 64 is inserted into the inner cavity of the positioning tube 65, allowing the upper support frame 2 and the lower support frame 3 to rotate in the inner cavity of the support base 1. Then, the user inserts the test tube into the inner cavity of the insertion hole 4, and inserts the bottom of the test tube into the inner cavity of the positioning hole 5, causing the rubber pad 7 to deform to elastically clamp the test tube. During use, water droplets that may be generated on the surface of the test tube fall to the bottom of the inner cavity of the support base 1, and the water droplets are absorbed by the water-absorbing pad 9.

[0025] In summary, this cell refrigeration test tube support rack, through the setting of the docking component 6, allows the upper support frame 2 and the lower support frame 3 to be connected and fixed. At the same time, the cooperation of the support base 1, the upper support frame 2, the lower support frame 3, the insertion hole 4 and the positioning hole 5 supports and positions the test tubes, so that multiple test tubes can be placed in an orderly manner, thereby achieving the purpose of stable placement and easy handling.
