Cell storage test tube rack

Abstract

This utility model relates to the field of cell storage technology and discloses a cell storage test tube rack, including a base, a rotating tray movably mounted on the top surface of the base, a fixing component provided on the side of the rotating tray, a support column fixed above the rotating tray, a retaining ring fixed above the support column, and a fan provided on the side of the retaining ring. By opening the lid of the cryogenic storage box and placing ice packs, and then starting the fan after the test tubes are placed on the rack, the airflow goes through the air supply pipe to the air inlet ring, is dispersed by the nozzle, and flows into the partition ring through the ventilation hole, carrying away the heat of the cryogenic storage box and blowing cold air towards the outer wall of the test tubes, maintaining a low-temperature environment for short-term cell transport, avoiding high-temperature shock, and improving storage stability. When adapting to test tubes of different sizes, rotating the handle moves the retaining column in the groove, causing the adjusting blade to unfold or retract. After adjustment, pulling the positioning ring stretches the spring, compresses the silicone elastic clip, and locks it into the slot. When taking out the test tube, rotating the adjusting ring in the opposite direction or pressing the handle opens the blade and it can be taken out.

Description

Technical Field

[0001] This utility model relates to the field of cell storage technology, specifically to a cell storage test tube rack. Background Technology

[0002] With the rapid development of cell biology, gene therapy, regenerative medicine and other fields, higher requirements have been placed on the storage, transportation and handling of cell samples. Cell storage requires strict temperature control (such as liquid nitrogen environment), avoidance of contamination, and ensuring sample traceability. As a sample carrier, test tube racks need to meet the characteristics of freeze resistance, corrosion resistance, and antistatic properties, while having standardized specifications (such as adapting to cryopreservation tubes of different volumes, such as 1.5mL, 5mL, etc.) to adapt to the robotic arm grasping and positioning of automated storage equipment (such as liquid nitrogen tanks, low temperature freezers).

[0003] Chinese patent CN216538586U discloses a test tube rack for storing dendritic cells, including a shell assembly and an adjustment assembly. The shell assembly includes a box body, a box cover, and buffer support legs. The box cover is connected to the top of the box body, and the buffer support legs are connected to the bottom of the box body. A cover is fixed to the outer sides of the box body. A rotating connector is rotatably connected to the cover. A threaded rod is disposed inside the cover. A second bevel gear is fixedly sleeved on the other end of the threaded rod. The second bevel gear is meshed with the first bevel gear. A placement plate is disposed inside the box body. Both ends of the placement plate are threadedly connected to the threaded rod. Insertion holes are provided on the placement plate, which facilitates the sealed placement of test tubes, the adjustment of the placement height of test tubes in the sealed device, and the easy removal and placement of test tubes.

[0004] However, the following shortcomings still exist:

[0005] In current short-term cell transport, the lack of effective methods for maintaining low temperatures makes cells susceptible to temperature shock due to high summer temperatures. At the same time, the mismatch between the aperture of the test tube rack and the test tube specifications can easily cause the test tubes to slip off, leading to cell sample leakage. Therefore, those skilled in the art provide a cell storage test tube rack to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a cell storage test tube rack to solve the problems mentioned in the background section of the prior art.

[0007] This utility model provides the following technical solution: a cell storage test tube rack, including a base, a rotating tray movably mounted on the top surface of the base, a fixing component provided on the side of the rotating tray, a support column fixed above the rotating tray, a retaining ring fixed above the support column, a fan provided on the side of the retaining ring, an air supply pipe connected above the fan, and an air inlet ring provided inside the retaining ring.

[0008] As a preferred embodiment of the above technical solution, the inner diameter of the rotating tray is provided with a rack one, the upper part of the rotating tray is provided with a fixing ring, and the lower outer diameter of the fixing ring is provided with a rack two, which meshes with the rack one.

[0009] As a preferred embodiment of the above technical solution, the fixing component includes a handle, a tension spring, a positioning ring, a silicone elastic clip, and a slot. The handle is fixed to one side of the outer diameter of the rotating tray, the tension spring is disposed on the bottom surface of the handle, the positioning ring is fixed to the bottom surface of the tension spring, the silicone elastic clip is symmetrically disposed on both sides of the positioning ring, and the slot is opened on the top surface of the rotating tray. The slot, the positioning ring, and the silicone elastic clip are positioned correspondingly.

[0010] As a preferred embodiment of the above technical solution, the fan is connected to the air inlet ring via an upper air supply pipe. The air supply pipe is connected to a nozzle located on one side of the air inlet ring via a through retaining ring. Several nozzles are provided. A spacer ring is fixed inside the retaining ring. Several freeze storage boxes are provided on the top surface of the spacer ring. Several ventilation holes are opened on the outer diameter of the spacer ring. The ventilation holes correspond to the positions of the nozzles.

[0011] As a preferred embodiment of the above technical solution, a second positioning ring is provided inside the spacer ring, a second support column is fixed on the top surface of the second positioning ring, and a placement ring is fixed on the top surface of the second support column.

[0012] As a preferred embodiment of the above technical solution, the top surface of the placement ring is provided with a plurality of insertion hole assemblies, and a fixing component is mounted on one side of each insertion hole assembly. The insertion hole assembly includes an adjusting ring, an adjusting blade, a locking post, a connecting ring, a groove, and a slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model involves opening the lid of the cryogenic storage box, placing ice packs inside, and then starting the fan after the test tubes are placed on the shelf. The airflow travels through the air supply pipe to the air inlet ring, is dispersed by the nozzle, and flows into the partition ring through the ventilation holes. This removes heat from the cryogenic storage box and blows cold air toward the outer wall of the test tubes, maintaining a low-temperature environment for short-term cell transport, avoiding high-temperature shock, and improving storage stability.

[0015] 2. When this utility model is adapted to test tubes of different sizes, rotating the handle will move the locking pin in the groove, causing the adjusting blade to expand or contract. After adjustment, pulling the positioning ring and tension spring will compress the silicone elastic clip and lock it into the slot. When taking out the tube, rotating the adjusting ring in the opposite direction or pressing the handle will open the blade and allow it to be taken out. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figures 1-8As shown, this utility model provides a technical solution: a cell storage test tube rack, including a base 1, a rotating tray 2 movably mounted on the top surface of the base 1, a fixing component 3 provided on the side of the rotating tray 2, a support column 4 fixed above the rotating tray 2, a retaining ring 5 fixed above the support column 4, a fan 6 provided on the side of the retaining ring 5, an air supply pipe 7 connected above the fan 6, and an air inlet ring 8 provided inside the retaining ring 5.

[0028] As one implementation method in this embodiment, please refer to Figure 3 As shown, the inner diameter of the rotating tray 2 is provided with a rack 201, the upper part of the rotating tray 2 is provided with a fixing ring 202, and the lower outer diameter of the fixing ring 202 is provided with a rack 203, which meshes with the rack 201.

[0029] Furthermore, when the rotating tray 2 rotates under the push of the handle 301, the rack 1 201 inside it is engaged with the rack 2 203 on the bottom surface of the fixed ring 202. Through the meshing transmission of rack 1 201 and rack 2 203, not only can the angle of the rotating tray 2 be adjusted, but also, after being adjusted to the target position, the mechanical locking effect between the gears can effectively suppress the rotation or shaking of the rotating tray 2, significantly improving its structural stability in the working state. The rotating tray 2 can quickly position the test tubes and improve the efficiency of taking them out.

[0030] As one implementation method in this embodiment, please refer to Figure 6 As shown, the fixing component 3 includes a handle 301, a tension spring 302, a positioning ring 303, a silicone elastic clip 304, and a slot 305. The handle 301 is fixed to one side of the outer diameter of the rotating tray 2. The tension spring 302 is disposed on the bottom surface of the handle 301. The positioning ring 303 is fixed to the bottom surface of the tension spring 302. The silicone elastic clips 304 are symmetrically disposed on both sides of the positioning ring 303. The slot 305 is opened on the top surface of the rotating tray 2. The positions of the slot 305, the positioning ring 303, and the silicone elastic clip 304 are corresponding.

[0031] Furthermore, during use, the user holds the handle 301 and pushes the rotating tray 2 to flexibly adjust its position. When the operation is finished or the tube rack needs to be moved, simply pull down the positioning ring 303, and the tension spring 302 will extend accordingly. At this time, gently press the two sides of the silicone elastic clip 304 to make it retract inward, insert the positioning ring 303 into the slot 305, and then release it. The silicone elastic clip 304 will return to its original position by its own elasticity, tightly locking the inner wall of the slot 305 and firmly locking the positioning ring 303. This effectively prevents the rotating tray 2 from rotating during transportation, greatly enhancing its stability and reliability.

[0032] As one implementation method in this embodiment, please refer to Figures 7-8As shown, the fan 6 is connected to the air inlet ring 8 via the upper air supply pipe 7. The air supply pipe 7 is connected to the nozzle 81 located on one side of the air inlet ring 8 via the through retaining ring 5. Several nozzles 81 are provided. A partition ring 82 is fixed inside the retaining ring 5. Several freeze storage boxes 83 are provided on the top surface of the partition ring 82. Several ventilation holes 84 are opened on the outer diameter of the partition ring 82. The ventilation holes 84 correspond to the positions of the nozzles 81.

[0033] Furthermore, open the top cover of the cryopreservation box 83, place the ice pack inside the cryopreservation box 83, and after the test tubes are placed on the shelf, start the fan 6. The airflow generated by the fan is delivered to the air inlet ring 8 through the air supply pipe 7. The airflow is dispersed into multiple streams of airflow by multiple nozzles 81 on the side of the ring and sprayed evenly. The nozzles 81 correspond to the ventilation holes 84 on the outer diameter of the partition ring 82. The dispersed airflow enters the interior of the partition ring 82 through the ventilation holes 84 and flows around the cryopreservation box 83, carrying away heat and blowing the cold air emitted by the ice packs inside the box directly onto the outer wall of the test tubes. Therefore, a low temperature environment can be maintained during short-term cell transport, avoiding cell temperature shock caused by high summer temperatures and significantly improving cell storage stability.

[0034] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the top surface of the placement ring 92 is provided with several insertion hole assemblies 10, and a fixing component 3 is assembled on one side of the insertion hole assembly 10. The insertion hole assembly 10 includes an adjusting ring 1001, an adjusting blade 1002, a locking post 1003, a connecting ring 1004, a groove 1005, and a slot 1006. The adjusting ring 1001 is movably installed on the top surface of the placement ring 92. The adjusting blade 1002 is located inside the upper part of the adjusting ring 1001. Several adjusting blades 1002 are provided. The locking post 1003 is located on one side of the adjusting blade 1002. The connecting ring 1004 is located above the adjusting ring 1001. The groove 1005 is opened on the bottom surface of the connecting ring 1004. The groove 1005 and the locking post 1003 are positioned correspondingly. The slot 1006 is opened inside the connecting ring 1004 and on the top surface of the adjusting blade 1002.

[0035] Furthermore, when adapting to test tubes of different sizes, the user rotates the handle 301 of the fixing component 3, causing the locking post 1003 on one side of the adjusting blade 1002 to rotate and move within the groove 1005, so that the adjusting blade 1002 expands or contracts to match the test tube size. After adjustment, the user pulls the positioning ring 303 to stretch the spring 302, and gently presses the two sides of the silicone elastic clip 304 to retract it, so that the positioning ring 303 is embedded into the slot 1006 on the top surface of the connecting ring 1004 and the adjusting blade 1002. After insertion, the silicone elastic clip 304 resets by its elasticity and locks the slot 1006, achieving a firm lock. When removing the test tube, the user rotates the adjusting ring 1001 in the opposite direction or presses the handle 301, and the adjusting blade 1002 opens to easily remove the tube.

[0036] Working principle: Open the cryogenic storage box 83 and place ice packs inside. After the test tubes are placed on the shelf, start the fan 6. The airflow passes through the air supply pipe 7, the nozzle 81 of the air inlet ring 8, and the ventilation hole 84, carrying away the heat from the cryogenic storage box 83 and blowing it towards the outer wall of the test tubes. This maintains the low temperature, prevents cell hyperthermia, and improves storage stability. When adapting to different test tubes, rotate the handle 301 to drive the adjusting blade 1002 to expand or contract via the locking post 1003. After adjustment, pull the positioning ring 303 to stretch the spring 302, and press the silicone elastic clip 304 to engage with the slot 1006 and lock it in place. To remove the test tubes, rotate the adjusting ring 1001 in the opposite direction or press the handle 301 to open the adjusting blade 1002 and remove the tubes. At the same time, pushing the handle 301 causes the rack 201 of the rotating tray 2 to mesh with the rack 203 of the fixing ring 202, which facilitates angle adjustment and mechanical locking after positioning, improving stability and enabling rapid positioning of test tubes. During the rotation of the rotating tray 2, the support 4, retaining ring 5, positioning ring 9, support 91, and placement ring 92 rotate and move synchronously, making it easy to pick up the test tubes. After use or when moving, pull down the positioning ring 303 to stretch the spring 302, press the silicone elastic clip 304 to retract into the slot 305, and release it to reset and lock, preventing the rotating tray 2 from rotating accidentally.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
