Description

Technical Field

[0001] The utility model relates to the technical field of cell transport devices, and in particular to a cell transport device. Background Art

[0002] With the rapid development of cell biology, especially stem cell biology, cell therapy has made great progress in the field of basic research. Some research results have begun to be applied in clinical trials of various diseases such as cardiovascular system diseases, nervous system diseases, musculoskeletal diseases, diabetes, etc. At present, cell therapy is mostly implemented in hospitals, but hospitals do not have standard cell production laboratories. Therefore, hospitals need to establish long-term cooperation with companies engaged in cell production. Since cell quality is easily affected by the surrounding environment and transportation conditions, cell transportation is a key link.

[0003] A cell transport box disclosed in the prior art with the publication number "CN219565973U" includes a transport box body for storing reagent tubes, wherein a limiting device for protecting the reagent tubes is provided inside the transport box body, and the limiting device includes a support plate, a limiting plate and a plurality of tube sleeves for protecting the reagent tubes, the support plate and the limiting plate are both fixed inside the transport box body, the limiting plate is located at the top of the support plate, one end of the tube sleeve is fixedly connected to the top of the limiting plate, and the end of the tube sleeve away from the top of the limiting plate passes through the bottom of the limiting plate and extends to the bottom of the support plate.

[0004] Although the above technical solution protects the cells through the tube sleeve during transportation, which to a certain extent reduces the probability of the reagent tubes being damaged by the dry ice due to vehicle bumps, when taking individual reagent tubes, after opening the box lid, the dry ice will quickly come into contact with the relatively hot outside air, causing temperature changes, which may destroy the constant temperature state in the box and affect the remaining reagent tubes; in addition, when transporting the reagent tubes on bumpy roads, since only the sleeve is used for protection, the reagent tubes have poor anti-bumping ability, which may cause an impact and have poor practicality.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, this embodiment proposes a cell transport device, including an insulated box 11, a storage cabinet 12 for storing dry ice, which is slidably connected to the lower side of the insulated box 11. The dry ice can be replaced through the storage cabinet 12, thereby reducing the damage of the dry ice to the inner wall of the insulated box 11 and increasing the service life of the insulated box 11. The box cover 14 for sealing the insulated box 11 is detachably fixedly connected to the upper side of the insulated box 11, and the insulation component 3 for maintaining constant temperature in the insulated box 11 is connected between the box cover 14 and the storage cabinet 12. With the help of the thermal insulation component 3, when individual reagent tubes 2 are taken, the temperature in the thermal insulation box 11 will not have much contact with the outside air, thereby keeping the temperature in the thermal insulation box 11 stable, and keeping all cells that need to be transported stable. Several reagent tubes 2 that store and protect cells that need to be transported are connected to the thermal insulation component 3. The reagent tubes 2 provide multi-layer protection for the stored cell fluid, so that the cell fluid stored in the reagent tubes 2 can be better protected, thereby increasing the stability of cell transportation.

[0025] like Figures 2 to 4 As shown, the insulation component 3 includes a first insulation plate 31 and a second insulation plate 32, and the first insulation plate 31 and the second insulation plate 32 are fixedly connected to the inner wall of the insulation box 11, and several insulation tanks 33 are connected between the first insulation plate 31 and the second insulation plate 32. Each limiting ring 35 is fixedly connected in each insulation tank 33, and the lower side of the limiting ring 35 is connected to several air bags 34. The reset block 36 is slidingly connected to the inner wall of the lower side of the insulation tank 33. The reset block 36 guides the movement of the reagent tube body 2 in the insulation tank 33, reduces the friction between the storage tube 25 and the insulation tank 33, protects the outer surface of the storage tube 25, and increases the service life of the storage tube 25, thereby reflecting the protection effect of the cell fluid in the storage tube 25. The reset column 37 is fixedly connected to the lower side of the reset block 36, and the limit plate 39 is fixedly connected to the end of the reset column 37 away from the reset block 36.

[0026] like Figures 2 to 4 As shown, several air flow grooves 331 are opened on the lower side of the insulation tank 33, and each air injection hole 332 is opened on the upper side of each air flow groove 331. The air injection hole 332 is communicated with the air bag 34. When the reset block 36 is on the upper side of the air injection hole 332 and does not block the air injection hole 332, the total amount of gas in the insulation box 11 is the same. To compare the air bag 34 with external surface tension, most of the gas passes through the air flow grooves 331 and accumulates in the cavity between the lower wall of the reset block 36 and the bottom wall of the insulation box 11. However, when the reset block 36 gradually moves downward, the total amount of gas remains unchanged, and the gas will flow into the air bag 34 from the air injection hole 332, thereby causing the air bag 34 to expand. Then, the air bag 34 with low-temperature gas will fit tightly with the storage tube 25 to refrigerate the storage tube 25, increase the fixed limiting effect on the storage tube 25, and also buffer and offset some of the vibrations caused by transportation bumps, further increasing the stability of the storage tube 25 in transportation.

[0027] like Figure 2 and Figure 3 As shown, the reset column 37 is slidingly connected to the insulation tank 33, and the reset spring 38 is sleeved on the reset column 37. The reset spring 38 can cushion the vibration when bumps occur during transportation, so that the vibration caused by the bumps will not be directly transmitted to the reagent tube body 2. At the same time, when the reagent tube body 2 needs to be separated from the insulation tank 33, the released spring force can push the reagent tube body 2 out of the first insulation plate 31, which is convenient for users to take it, thereby ensuring the stable transportation of the reagent tube body 2. The two ends of the reset spring 38 are respectively in contact with the reset block 36 and the bottom wall of the insulation tank 33.

[0028] like Figure 4As shown, the reagent tube body 2 includes a storage tube 25, the lower end of the storage tube 25 abuts against the upper end of the reset block 36, and the upper end of the storage tube 25 is threadedly connected to the sealing cover 21. Through the threaded connection, the cell fluid stored in the storage tube 25 will not leak easily. The sealing block 24 is fixedly connected to the side of the sealing cover 21 facing the storage tube 25, and the outer wall of the sealing block 24 abuts against the inner wall of the storage tube 25. The sealing block 24 further improves the storage effect of the cell fluid.

[0029] like Figure 4 As shown, the two clamping blocks 23 are symmetrically fixedly connected to the outer cylindrical surface of the sealing cover 21 with the axis of the sealing cover 21 as the center, and the two clamping grooves 333 are both opened on the upper inner wall of the insulation tank 33. Each clamping block 23 abuts against the inner wall of each clamping groove 333. The user presses down on the sealing cover 21 so that each clamping block 23 can slide along the inner wall of the clamping groove 333 and then be clamped with the insulation tank 33, so that the insulation tank 33 can limit the reagent tube body 2 and prevent the reagent tube body 2 from falling out during transportation.

[0030] like Figure 3 and Figure 4 As shown, the upper side surface of the reset block 36 is the same shape as the lower end of the storage tube 25, which reduces the gap between the reset block 36 and the storage tube 25 so that when bumps occur, the reset block 36 and the storage tube 25 will not collide with each other, so that the storage tube 25 remains stable during storage.

[0031] like Figures 1 to 4 As shown, a first handle 22 is fixedly connected to the upper side of the sealing cover 21, a second handle 13 is fixedly connected to the outside of the storage cabinet 12, and a third handle 15 is fixedly connected to the box cover 14. The various handles make it convenient for users to take and use the device.

[0032] The working principle of this embodiment is:

[0033] First, place a certain amount of dry ice in the storage cabinet 12, then push the storage cabinet 12 into the insulation box 11, seal it, wait for a while, and wait for the temperature under the first insulation board 31 to reach the appropriate temperature before continuing to the next step;

[0034] The cell fluid to be transported is placed in the storage tube 25, and then the sealing cover 21 with the sealing block 24 is threadedly connected to the storage tube 25, and the sealing block 24 abuts against the inner wall of the storage tube 25 to achieve a double sealing effect on the cell fluid, ensuring the sealing effect of the cell fluid, and then grasp the first handle 22 to press the reagent tube body 2 into the insulation tank 33, and then make the bottom of the storage tube 25 abut against the reset block 36, let the clamping block 23 move down along the clamping groove 333, and then rotate it, and then clamp it with the clamping groove 333, so that the reagent tube body 2 and the insulation tank 33 are clamped, and then closed. The downward movement of the positioning block 36 will gradually reduce the air pressure in the heat preservation tank 33, so that the cold gas on the lower side of the second heat preservation plate 32 is pressed into the air bag 34 from the air injection hole 332, so that the multiple air bags 34 with cold air masses are completely in close contact with the tube wall of the storage tube 25, transferring the temperature to the storage tube 25 and cooling the storage tube 25. When the transportation is bumpy, the return spring 38 below will reduce some of the vibration effect, and the air bag 34 filled with cold air can also reduce some of the vibration effect. After all the reagent tubes 2 are installed, the box cover 14 is closed to ensure the overall heat preservation effect of the heat preservation box 11.

[0035] When it is necessary to take out individual or multiple reagent tubes 2, the box cover 14 is separated from the insulation box 11, and then the required reagent tube 2 is selected. The first handle 22 on the reagent tube 2 needs to be rotated in the opposite direction when installed to make the clamping block 23 disengage from the clamping groove 333, and then the spring force of the reset spring 38 is released to push the reagent tube 2 out of the first insulation plate 31, making it convenient for users to take it out.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
