[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5An easy-to-access embryo storage cryopreservation device includes a cryopreservation device body 1, a plurality of lifting cylinder assemblies 11 are placed at equal intervals inside the cryopreservation device body 1, a T-shaped fixing block 111 is provided on the top of the lifting cylinder assembly 11, and an auxiliary lifting assembly 2 is provided on the outside of the top of the cryopreservation device body 1. The auxiliary lifting assembly 2 includes an annular guide rail 21, a limit slider is slidably provided inside the annular guide rail 21, and a movable seat assembly 22 is vertically fixedly installed on the top of the limit slider.

[0023] It is worth noting that the specific structure and working principle of the cryogenic storage device body 1 and the lifting cylinder assembly 11 are existing technologies that are already publicly available on the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0024] Meanwhile, the movable seat assembly 22 is externally slidably fitted with a movable block 23. The movable block 23 is equipped with a first slider 233 and a second slider 234 at equal intervals. The bottom of the second slider 234 is connected to a limit block 24. The first slider 233 is equipped with a drive motor 3. The output end of the drive motor 3 is connected to a rotating shaft. One end of the rotating shaft is connected to the limit block 24.

[0025] Furthermore, the movable seat assembly 22 includes a fixed seat, on the top of which a fixed rod and a limiting seat are installed in sequence, and a through hole is provided in the movable block 23 at the fixed rod.

[0026] Meanwhile, a second groove 232 is provided in the movable block 23 at the first slider 233 and the second slider 234, and an annular groove 231 is provided in the movable block 23 at the first slider 233.

[0027] Furthermore, a limiting slot is provided on the side of the limiting block 24 away from the fixing rod and located at the T-shaped fixing block 111.

[0028] Furthermore, the lifting cylinder assembly 11 includes a lifting cylinder body, a lifting cylinder rod fixedly installed on one side of the lifting cylinder body, and an auxiliary rod installed on the top of the lifting cylinder rod. A T-shaped fixing block 111 is installed on the top of the auxiliary rod. The auxiliary rod and the lifting cylinder body are on the same vertical line.

[0029] Furthermore, a placement cavity is provided inside the first slider 233 at the location of the drive motor 3.

[0030] It is worth noting that when the second slider 234 is located in the second slide groove 232 and close to the fixed rod, its limiting slider is located outside the lifting cylinder assembly 11. When the first slider 233 is located in the second slide groove 232 and away from the fixed rod, its second slider 234 is located in the annular slide groove 231. At this time, when the drive motor 3 drives the limiting block 24 to rotate, its second slider 234 slides in the annular slide groove 231.

[0031] In this embodiment, by moving the limiting slider to the outside of the lifting cylinder assembly 11, the auxiliary picking component 2 slides within the annular guide rail 21 under the action of the limiting slider until it is aligned with the lifting cylinder assembly 11. Then, after inserting the limiting slider into the T-shaped fixing block 111 of the corresponding lifting cylinder assembly 11, the movable block 23 is moved upward by one distance, and the drive motor 3 is turned on. The drive motor 3 drives the limiting block 24 to rotate 180°, and then the drive motor 3 is turned off. At the same time, the movable block 23 continues to move upward until the lifting cylinder assembly 11 is moved out of the fluid storage device body 1. The drive motor 3 is then turned on, and the drive motor 3 drives the limiting block 24 to rotate 180°. At this time, the lifting cylinder body is located outside the inlet and outlet of the cryopreservation device body 1. Then, the cryopreservation tube containing the embryo is placed inside the lifting cylinder assembly 11.

[0032] After placement, the drive motor 3 is turned on, and the limit block 24 is rotated 180° by the drive motor 3. At this time, the lifting cylinder body is located at the inlet and outlet of the freeze storage device body 1. The movable block 23 is moved downward until the lifting cylinder body is inside the freeze storage device body 1 and its auxiliary rod is close to the inlet and outlet of the freeze storage device body 1. The drive motor 3 is turned on, and the limit block 24 is rotated 180° by the drive motor 3. The movable block 23 is moved downward until the auxiliary rod is placed on the top of the freeze storage device body 1, thus completing the entire retrieval operation. The entire retrieval process is convenient and avoids the risk of frostbite to the operator by direct contact with the lifting cylinder, thus improving the safety during the retrieval of the lifting cylinder assembly 11.

[0033] In this invention, the auxiliary lifting component 2 assists in taking out the lifting cylinder component 11 from the frozen storage device. The entire removal process is convenient while ensuring stability during the lifting process, avoiding the risk of frostbite to the operator from direct contact with the lifting cylinder, and improving the safety during the lifting cylinder component 11 removal process.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
