[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figures 1-6 This utility model provides a technical solution: a highly protective stem cell transport device, including a transport cylinder 1, a medium storage sleeve 9 installed in the inner cavity of the transport cylinder 1, the medium storage sleeve 9 being filled with a cold-keeping medium, an overflow groove for controlling the flow of the cold-keeping medium on the top of the medium storage sleeve 9, and a bucket cover 2 on the top of the transport cylinder 1.

[0047] The placement mechanism 3 is located inside the transfer cylinder 1 and is situated within the medium storage sleeve 9. The material to be transferred is placed through the placement mechanism 3.

[0048] The separating mechanism 8 is located inside the medium storage sleeve 9 and separates the placement mechanism 3.

[0049] The designed placement mechanism 3 and separation mechanism 8 can fully limit the position of stem cells during transport, which is beneficial to improve the protection and safety of stem cell transport. Furthermore, the designed separation mechanism 8 can divide the cavities within the medium storage sleeve 9, and with the adjustment of the flow rate of the cold insulation medium, it is convenient to adjust the cold insulation temperature in different cavities, thereby improving the zonal storage protection effect for test tubes with different cold insulation requirements.

[0050] The placement mechanism 3 includes: a placement rack 301, with multiple assembly holes 303 for accommodating test tubes through the top of the placement rack 301, a fixing post 302 connected to the bottom of the placement rack 301, the fixing post 302 being embedded in the bottom of the inner cavity of the transfer cylinder 1, and a handle 304 connected to the top of the placement rack 301, through which the placement rack 301 can be taken out.

[0051] The rotating ring 4 is connected to the outside of the placement rack 301. Multiple sets of flow grooves 5 are opened around the top of the rotating ring 4 along the axis. The number of overflow grooves corresponds to the number of flow grooves 5. Multiple overflow grooves are opened around the top of the medium storage sleeve 9. The cooling intensity is controlled by controlling the communication between the overflow grooves and the flow grooves 5.

[0052] Specifically: Through the designed placement mechanism 3, the placement rack 301 can drive the rotating ring 4 to rotate. The rotation of the rotating ring 4 can adjust the number of connections between the flow channel 5 and the overflow channel, which is beneficial to control the exchange intensity of the medium storage sleeve 9 to the internal cold preservation temperature, and facilitates adaptive adjustment according to different stem cell transport temperatures.

[0053] The top of the rotating ring 4 is provided with a stroke groove along the axis. A guide post 6 is slidably connected in the stroke groove. The bottom end of the guide post 6 is connected to the top of the medium storage sleeve 9. The rotation stroke of the rotating ring 4 is controlled by the sliding of the guide post 6 in the stroke groove.

[0054] The designed stroke groove and guide post 6 can control the rotation stroke of the rotating ring 4, preventing excessive rotation of the rotating ring 4 from affecting the connection between the flow groove 5 and the overflow groove.

[0055] The top of the medium storage sleeve 9 is provided with a medium filling port, which can be a valve port or an opening. The valve port is provided with a corresponding filling interface for filling with the cold insulation medium. The cold insulation medium is a liquid nitrogen or dry ice or other cold insulation liquid. This part is a mature technology in the field and will not be described further.

[0056] Multiple locking blocks 7 are connected around the outside of the placement frame 301, and the locking blocks 7 are engaged in the limiting groove opened at the top of the rotating ring 4;

[0057] Multiple limiting blocks are arranged inside the stroke groove, and the rotation of the rotating ring 4 is limited by the contact between the limiting blocks and the guide post 6;

[0058] Furthermore, the multiple limiting blocks arranged in the stroke groove can prevent the rotating ring 4 from rotating due to shaking, and facilitate the limiting stability after the placement frame 301 is inserted into the limiting groove by the outer locking block 7.

[0059] The designed locking block 7 and locking slot 809 facilitate the placement of the rack 301, thereby improving the stability of the device within the medium storage sleeve 9.

[0060] The bottom of the fixed column 302 is connected to a chuck 10, which is engaged in the chuck 11 connected to the bottom of the inner cavity of the transfer cylinder 1.

[0061] The outer periphery of the chuck 10 is connected with multiple protrusions, and the inner cavity of the chuck 11 is provided with multiple grooves around the axis. The rotation of the post 302 and the placement frame 301 is limited and fixed by the insertion of the protrusions in the grooves.

[0062] Specifically: Through the designed chuck 10 and chuck seat 11, test tubes can be inserted into the assembly hole 303 at the top of the placement rack 301, which helps to improve the stability of the test tube device by limiting the position of the assembly hole 303. The fixing column 302 is inserted into the chuck seat 11 by the chuck 10, which helps to limit the circumferential rotation of the fixing column 302 and facilitates the improvement of the stability of test tube assembly.

[0063] The separating mechanism 8 includes: a track groove 801, which is connected to the bottom of the inner cavity of the transfer cylinder 1, and the track groove 801 has an annular sliding cavity;

[0064] The slide block 802 is slidably connected to the sliding cavity of the track groove 801, and the top of the slide block 802 is connected to the limit post 805;

[0065] Partition 803, with a retainer 804 connected to the bottom of partition 803, the retainer 804 being inserted and connected to the outside of the limiting post 805, partition 803 being located inside the medium storage sleeve 9, and the partition 803 sealing the inside of the medium storage sleeve 9 to form different accommodating cavities.

[0066] It also includes: a sliding sleeve connected to both sides of the slide block 802, a sliding rod 806 slidably connected inside the sliding sleeve, and an abutment plate 808 connected to the bottom end of the sliding rod 806. The movement of the slide block 802 and the partition plate 803 is limited by the contact between the abutment plate 808 and the bottom side of the inner cavity of the track groove 801.

[0067] The first spring 807 is sleeved on the outside of the slide rod 806, and the two ends of the first spring 807 are respectively connected to the corresponding positions on the side of the slide sleeve and the abutment plate 808;

[0068] The slide groove 811 is formed on one side of the slide block 802. The slide groove 811 is slidably connected to the stepped ring connected to the inner cavity of the track groove 801. The axial runout of the slide block 802 is limited by the sliding of the slide groove 811 outside the stepped ring.

[0069] Specifically: Through the designed partition mechanism 8, different accommodating cavities can be formed by the fit between the partition 803 and the limiting post 805, so that the test tubes in the accommodating cavities are at the same storage temperature. Furthermore, by selecting the flow ports of different sized flow channels 5, the overflow of the cold insulation medium can be adjusted, thereby forming accommodating cavities with different cold insulation temperatures within the same medium storage sleeve 9, and controlling the transport temperature of different stem cells.

[0070] A single flow channel 5 includes multiple flow ports, and the flow port gaps of multiple flow channels 5 are different to adapt to the medium flow efficiency of different cavities. By the different flow port gaps between multiple flow channels 5, the cold preservation effect of different cavities can be controlled in zones.

[0071] Furthermore, the slide block 802 is designed so that the sliding rod 806 can be pulled to separate the abutment plate 808 from the bottom slot 809 of the track groove 801. At this time, the slide block 802 can be rotated to adjust the angle of the partition plate 803 relative to the limiting post 805, which is beneficial to adjust the size of different cold-keeping cavities.

[0072] Furthermore, the receiving cavity should be located on one side of the flow channel 5 corresponding to the single set, so that the cold insulation medium flowing out of the flow channel 5 can fully cool the receiving cavity;

[0073] The inner cavity of the track groove 801 is provided with multiple slots 809 around the axis, and the size of the slots 809 matches the abutment plate 808. The locking of the abutment plate 808 in the slots 809 improves the limiting stability of the slide block 802.

[0074] It also includes: a bonding cover 810, which is connected to the side of the partition 803 near the fixed post 302. The bonding cover 810 has an arc-shaped cross section and is used to bond to the fixed post 302 to seal the gap.
