Description
Technical Field
[0001] This utility model belongs to the field of stem cell sampling technology, and specifically relates to a stem cell sampling storage device. Background Technology
[0002] Stem cells are a type of cell with the potential for self-renewal and differentiation. They can generate various cell types and have the ability to maintain the body's balance and repair damaged tissues. Stem cell sampling storage devices are specially designed to preserve stem cell samples. These devices usually have cryopreservation and monitoring systems to ensure the integrity and functionality of stem cells during storage.
[0003] Announcement No. "CN221438852U" discloses a storage device with an adjustable function, which solves the problems mentioned in the background art. The device includes a cylindrical body with a detachable cap at the top. A test tube holder is located inside the cylindrical body, and the holder has placement holes arranged in a symmetrical ring about a central center. Test tubes are placed in the placement holes. Rotating shafts are symmetrically installed on the side walls of the holder, and through holes are symmetrically opened on the side walls of the cylindrical body. Both ends of the rotating shafts are rotatably connected to a crank handle fixed to one end of each through hole. This invention eliminates the need to remove test tubes containing stem cell samples from the storage device during sampling. The device allows adjustment of the test tube's tilt angle, avoiding disturbance of cell precipitation and facilitating sampling from specific layers, thus improving sampling efficiency and effectiveness.
[0004] While the aforementioned utility model eliminates the need to remove the test tube containing the stem cell sample from the storage device during sampling, and utilizes the device to adjust the tilt angle of the test tube to avoid disturbing cell precipitation and facilitate sampling from specific layers, thus improving sampling efficiency and effectiveness, the test tube is simply placed in the placement hole without a stable fixation method. When moving the storage device or performing other operations, the test tube is easily displaced due to shaking or collision, or even falls out of the placement hole. This not only leads to sample confusion but also damages the test tube, affecting the integrity of the stem cells and the storage effect. Utility Model Content
[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a stem cell sampling storage device that solves the problem of simply placing test tubes in the placement hole without a stable fixation method. When moving the storage device or performing other operations, the test tubes are easily displaced due to shaking or collisions, or even fall out of the placement hole. This not only leads to sample confusion but also damages the test tubes, affecting the integrity of the stem cells and the storage effect.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A storage device for stem cell sampling includes a storage cylinder body. An electric telescopic rod is symmetrically installed at the bottom of the storage cylinder body. A lifting plate is fixedly connected to the telescopic end of the electric telescopic rod. A fixed column is fixedly connected to the upper end of the lifting plate. A test tube placement tray is movably connected to the other end of the fixed column. Placement holes are symmetrically opened in a circular circumferential array at the upper end of the test tube placement tray. Installation grooves are symmetrically opened in the inner wall of the placement holes. Clamping components are installed inside the installation grooves. A cylinder cover is movably connected to the upper end of the storage cylinder body.
[0008] The clamping assembly includes a mounting base, a first positioning post, an internal hole, a first return spring, a second positioning post, a movable post, and an arc-shaped clamping seat. The arc-shaped clamping seats are symmetrically arranged inside the placement hole. A movable post is fixedly connected to one end of each arc-shaped clamping seat. Mounting bases are fixedly connected to one end of the mounting groove and one end of the movable post. A first positioning post is fixedly connected to one end of each mounting base inside the mounting groove. An internal hole is formed at the other end of the first positioning post. A first return spring is fixedly connected to one end of the internal hole, and a second positioning post is fixedly connected to the other end of the first return spring. The second positioning post is slidably connected to the internal hole. The other end of the second positioning post is fixedly connected to the mounting base at one end of the movable post. A second return spring is sleeved on the outer side of both the first and second positioning posts. The two ends of the second return spring are fixedly connected to the opposite ends of the mounting base, respectively. This assembly can tightly secure the test tube, preventing it from shaking or tipping over during storage. It also provides effective cushioning and protection when the test tube is subjected to external impact or vibration, helping to prevent breakage or leakage, thereby ensuring the safe storage of stem cell samples.
[0009] As a preferred technical solution, an anti-slip pad is fixedly connected to one end of the arc-shaped clamp. The surface of the anti-slip pad is provided with anti-slip texture. The anti-slip pad is made of soft rubber, which can significantly increase the friction between the arc-shaped clamp and the test tube, prevent the test tube from accidentally sliding or tipping over on the storage rack, and also form a buffer layer between the test tube and the arc-shaped clamp.
[0010] As a preferred technical solution, a threaded column is fixedly connected to the upper end of the fixed column, and a threaded hole is opened at the upper end of the test tube placement tray. The threaded column and the threaded hole are threadedly connected, and a nut is threadedly connected to the outside of the threaded column. This allows the test tube placement tray to be easily pulled out of the storage cylinder body for thorough cleaning and disinfection, which helps to eliminate potential sources of contamination, maintain a clean and sterile storage environment, and thus ensure the safety of stem cell sample storage.
[0011] As a preferred technical solution, the inner wall of the storage cylinder is symmetrically fixed with guide blocks through an annular circumferential array. The outer walls of the test tube placement tray and the lifting plate are symmetrically provided with guide grooves through an annular circumferential array. The guide grooves and guide blocks are slidably connected, which ensures the stability of the test tube placement tray and the lifting plate during the lifting process. This can prevent the test tube placement tray or the lifting plate from shifting or shaking during lifting, thereby ensuring the safety and stability of the test tubes.
[0012] As a preferred technical solution, the bottom end of the storage cylinder is symmetrically and fixedly connected with a limiting tube, and the bottom end of the lifting plate is symmetrically and fixedly connected with a limiting column. The limiting column and the limiting tube are slidably connected, which ensures the stability and accuracy of the lifting plate during the lifting process and can prevent the lifting plate from shifting or shaking during the lifting process, thereby ensuring the safety and stability of the test tube placement tray connected to it.
[0013] As a preferred technical solution, a temperature display is installed on the upper end of the cylinder cover and a temperature sensor is installed on the bottom end of the cylinder cover. This allows for real-time monitoring of the internal temperature of the storage device, ensuring that the stem cell samples are in a suitable storage environment. Furthermore, it enables timely detection of temperature anomalies and the implementation of adjustment measures, thereby preventing damage to the stem cell samples due to excessively high or low temperatures and greatly improving the safety and reliability of the storage device.
[0014] In summary, the present invention has the following main advantages:
[0015] In this invention, the test tube is inserted into the placement hole above the test tube placement tray. During insertion, a squeezing force is applied to the arc-shaped end of the arc-shaped clamp, causing the arc-shaped clamp to move the moving column. The moving column then moves the second positioning column inside the built-in hole of the first positioning column. The second positioning column presses against the first return spring, compressing the first return spring. Simultaneously, the mounting seat at one end of the moving column presses against the mounting seat inside the mounting groove, compressing the second return spring. The arc-shaped clamp clamp securely holds and fixes the test tube, tightly securing it and preventing it from shaking or tipping over during storage. Furthermore, it effectively buffers and protects the test tube from external impacts or vibrations, helping to prevent breakage or leakage, thus ensuring the safe storage of stem cell samples.

[0021] Example
[0022] refer to Figures 1 to 4 The stem cell sampling storage device described in this embodiment includes a storage cylinder body 1. An electric telescopic rod 5 is symmetrically installed at the bottom of the storage cylinder body 1. A lifting plate 6 is fixedly connected to the telescopic end of the electric telescopic rod 5. A fixing column 7 is fixedly connected to the upper end of the lifting plate 6. A test tube placement tray 8 is movably connected to the other end of the fixing column 7. Placement holes 9 are symmetrically opened in a circular circumferential array at the upper end of the test tube placement tray 8. Installation grooves 15 are symmetrically opened in the inner wall of the placement holes 9. A clamping component 16 is installed inside the installation grooves 15. A cylinder cover 2 is movably connected to the upper end of the storage cylinder body 1.
[0023] The clamping assembly 16 includes a mounting base 161, a first positioning post 162, an internal hole 163, a first return spring 164, a second positioning post 165, a movable post 166, and an arc-shaped clamping seat 167. The arc-shaped clamping seats 167 are symmetrically arranged inside the placement hole 9. One end of the arc-shaped clamping seat 167 is fixedly connected to the movable post 166. The mounting base 161 is fixedly connected to one end of the mounting groove 15 and one end of the movable post 166. One end of the mounting base 161 inside the mounting groove 15 is fixedly connected to the first positioning post 162. The other end of the first positioning post 162 has an internal hole 163. One end of the internal hole 163 is fixedly connected to the first return spring 164, and the other end of the first return spring 164 is fixedly connected to the second positioning post 165. The second positioning post 165 is slidably connected to the internal hole 163, and the other end of the second positioning post 165 is connected to the movable post 166. The end mounting base 161 is fixedly connected. The first positioning post 162 and the second positioning post 165 are fitted with a second return spring 17 on their outer sides. The two ends of the second return spring 17 are fixedly connected to the opposite ends of the mounting base 161. When the test tube is inserted into the placement hole 9 above the test tube placement tray 8, the squeezing force applies pressure to the arc-shaped end of the arc-shaped clamping seat 167, causing the arc-shaped clamping seat 167 to move the moving post 166. The moving post 166 causes the second positioning post 165 to slide inside the built-in hole 163 of the first positioning post 162. The second positioning post 165 presses against the first return spring 164, and the first return spring 164 is compressed. At the same time, the mounting base 161 at one end of the moving post 166 presses against the mounting base 161 inside the mounting groove 15, and the second return spring 17 is compressed. The arc-shaped clamping seat 167 clamps and fixes the test tube.
[0024] refer to Figure 4 An anti-slip pad 18 is fixedly connected to one end of the arc-shaped clamping seat 167. The surface of the anti-slip pad 18 is provided with anti-slip texture. The anti-slip pad 18 is made of soft rubber. By setting the anti-slip pad 18, the friction between the arc-shaped clamping seat 167 and the test tube can be significantly increased, preventing the test tube from accidentally sliding or tipping over.
[0025] refer to Figure 3 A threaded post 12 is fixedly connected to the upper end of the fixed post 7. A threaded hole 13 is opened at the upper end of the test tube placement tray 8. The threaded post 12 and the threaded hole 13 are threadedly connected. A nut 14 is threadedly connected to the outside of the threaded post 12. Rotate the nut 14 to end the threaded connection between the nut 14 and the threaded post 12. Then rotate the test tube placement tray 8 to end the connection between the threaded hole 13 at one end of the test tube placement tray 8 and the threaded post 12. Then pull the test tube placement tray 8 out of the storage cylinder body 1 to complete the disassembly of the test tube placement tray 8.
[0026] refer to Figure 2The inner wall of the storage cylinder body 1 is symmetrically fixed with guide blocks 10 through an annular circumferential array. The outer walls of the test tube placement tray 8 and the lifting plate 6 are symmetrically provided with guide grooves 11 through an annular circumferential array. The guide grooves 11 and the guide blocks 10 are slidably connected. When the electric telescopic rod 5 is activated, the lifting plate 6 is controlled to drive the test tube placement tray 8 to rise and fall through the fixed column 7. When the lifting plate 6 and the test tube placement tray 8 are rising and falling, the lifting plate 6 and the test tube placement tray 8 drive the outer guide grooves 11 to slide outside the guide blocks 10 on the inner wall of the storage cylinder.
[0027] refer to Figure 2 The storage cylinder body 1 is symmetrically and fixedly connected to the bottom end of the limiting tube 20, and the lifting plate 6 is symmetrically and fixedly connected to the bottom end of the limiting column 19. The limiting column 19 and the limiting tube 20 are slidably connected. When the lifting plate 6 drives the test tube placement tray 8 to rise and fall through the fixed column 7, the lifting plate 6 drives the limiting column 19 to slide inside the limiting tube 20.
[0028] refer to Figure 2 A temperature display 3 is installed on the upper end of the cylinder cover 2, and a temperature sensor 4 is installed on the bottom end of the cylinder cover 2. When the temperature sensor 4 senses the temperature change inside the storage cylinder body 1, it converts it into an electrical signal, and then the temperature display 3 receives the electrical signal from the temperature sensor 4.
[0029] Operating principle and advantages: First, start the electric telescopic rod 5, control the lifting plate 6 to drive the test tube placement tray 8 to rise through the fixed column 7, and then insert the test tube into the placement hole 9 above the test tube placement tray 8. During the insertion process, the squeezing force applies pressure to the arc-shaped end of the arc-shaped clamping seat 167, causing the arc-shaped clamping seat 167 to drive the moving column 166 to move. The moving column 166 drives the second positioning column 165 to slide inside the built-in hole 163 of the first positioning column 162. The second positioning column 165 presses against the first return spring 164, and the first return spring 164 is compressed. At the same time, the mounting seat 161 at one end of the moving column 166 presses against the mounting seat 161 inside the mounting groove 15, and the second return spring 17 is compressed. The arc-shaped clamping seat 167 clamps and fixes the test tube. Finally, start the electric telescopic rod 5, control the lifting plate 6 to drive the test tube placement tray 8 to descend through the fixed column 7.
[0030] This invention can securely fix the test tube, preventing it from shaking or tipping over during storage. It can also effectively buffer and protect the test tube from external impacts or vibrations, helping to prevent the test tube from breaking or leaking, thereby ensuring the safe storage of stem cell samples.
