DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Depend on Figure 1-6 The utility model relates to an organoid cryopreservation cooling box, comprising a box body 1 and a box cover 2, wherein an upper magnetic column 3 is connected to the box cover 2, an annular plate 4 is provided in the box body 1, and a lower magnetic column 5 is connected to the center of the box body 1, the lower magnetic column 5 is located on the inner side of the annular plate 4, and the lower magnetic column 5 is magnetically matched with the upper magnetic column 3; an inner cavity 6 is formed in the lower magnetic column 5, and a lower magnetic plate 7 and an air bag 8 are provided in the inner cavity 6, the lower magnetic plate 7 is located below the air bag 8, and a telescopic spring 9 is provided in the air bag 8; a plurality of tube holes 10 are opened on the annular plate 4, and a plurality of small air bags 11 are fixedly provided in the tube holes 10 along the axial direction thereof, and the plurality of small air bags 11 are connected by short tubes 12, and the short tubes 12 are connected to the air bag 8 through a catheter;

[0026] With this design, when in use, the annular plate 4 is placed inside the box body 1. The material of the annular plate 4 can be selected according to actual needs, such as rubber or sponge. Then, the test tube to be placed is placed inside the tube hole 10. At this time, due to the action of the telescopic spring 9, the lower magnetic plate 7 abuts against the inner bottom wall of the inner cavity 6. At the same time, the small airbag 11 is in a contracted state. In this way, the inner diameter of the small airbag 11 is larger than the outer diameter of the test tube, so it is convenient to place the test tube.

[0027] Next, the box cover 2 is placed on the box body 1, so that the upper magnetic column 3 on the box cover 2 is magnetically attracted to the lower magnetic column 5 in the box body 1, so that the lower magnetic plate 7 squeezes the large air bag 8 and the telescopic spring 9. The internal volume of the large air bag 8 becomes smaller under pressure, so that the air inside it enters the small air bag 11 through the conduit and the short tube 12. After the small air bag 11 takes in air, it expands and abuts against the outer wall of the test tube, thereby realizing the fixation process of the test tube; at the same time, due to the setting of the large air bag 8 and the telescopic spring 9, the movement of the lower magnetic plate 7 can be relatively smooth, avoiding excessive collision of the lower magnetic plate 7 due to magnetic force.

[0028] Specifically, the overall shape of the air bag 8 is cylindrical, the top and bottom of the air bag 8 are both non-deformable entities, and the middle part of the air bag 8 is elastic and can be deformed under pressure; this design can make the air bag 8 have good strength.

[0029] Specifically, the inner bottom wall of the air bag 8 is fixedly provided with an integrated limiting column 13, and the telescopic spring 9 is wrapped around the outside of the limiting column 13; with this design, the movement distance of the lower magnetic plate 7 can be limited by the limiting column 13, thereby protecting the air bag 8 and the telescopic spring 9.

[0030] Specifically, the small airbags 11 are arranged in a linear array along the central axis of the tube hole 10 . The small airbags 11 are annular in shape, and the inner edges of the small airbags 11 are all rounded.

[0031] Specifically, the upper magnetic column 3 includes a column 14 and an upper magnetic plate 15 , wherein the column 14 is connected to the box cover 2 as a whole, and the upper magnetic plate 15 is fixedly embedded on one end of the column 14 close to the box body 1 .

[0032] Furthermore, a screw groove 16 is provided at the top of the lower magnetic column 5, and a stud 17 is connected to the inner thread of the screw groove 16. The stud 17 is T-shaped and has a tool groove 18. With this design, an external tool can be inserted into the tool groove 18 to drive the stud 17 to move. After the stud 17 is displaced by the thread, it squeezes the large air bag 8, thereby changing the position of the limit column 13 and adjusting the moving distance of the lower magnetic plate 7. The pressure of the small air bag 11 is controlled by changing the volume change of the large air bag 8 to ensure the fixing force of the test tube.

[0033] Furthermore, a barrel 19 is provided in the screw groove 16, and the barrel 19 is located between the stud 17 and the air bag 8, and the barrel 19 and the stud 17 are movably matched; such a design can prevent the stud 17 from contacting the air bag 8 through the barrel 19, thereby protecting the air bag 8.
