Description

Technical Field

[0001] This utility model relates to the field of animal serum sample storage technology, and in particular to an animal serum sample storage device. Background Technology

[0002] Animal serum samples are core materials in biomedical research, clinical diagnosis, and biopharmaceuticals, playing multiple crucial roles. Based on their source, composition, and application scenarios, their main functions can be systematically summarized as follows: 1. Animal serum (especially fetal bovine serum, FBS) is an important supplement to cell culture media, primarily providing basic nutrition and essential factors, promoting cell adhesion and morphology maintenance, and protecting and stabilizing the cellular environment; 2. Serum samples are core materials for disease diagnosis, serving as carriers for immunological detection, sources of controls and standards, and preventing detection interference; 3. Different serum types are suitable for different experimental needs: stem cell and special cell culture, virology and vaccine development, and molecular mechanism research. Animal serum samples, by providing nutrition, regulating metabolism, aiding adhesion, and stabilizing the environment, have become the "gold standard" for cell culture. Simultaneously, as a detection carrier for disease diagnosis and a cornerstone for research model construction, their value extends from basic research to clinical applications. Recent breakthroughs in preservation technology have further expanded their application potential in on-site testing and resource-scarce scenarios.

[0003] Currently, some animal serum samples are typically stored in cryogenic storage to maintain their activity and stability. However, opening the storage box when retrieving serum disrupts the internal cryogenic environment, allowing ambient air to penetrate and potentially affecting the storage quality of other serum samples. This limitation is particularly pronounced in cases of frequent retrieval or large-volume storage, as frequent opening and closing of the storage box exacerbates temperature fluctuations. Although existing technologies have attempted to mitigate this problem through methods such as partitioned storage, it remains difficult to completely eliminate the impact of temperature changes on samples in practice. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of some existing storage boxes, which are frequently opened during use, causing the internal low-temperature environment to be destroyed by the external room-temperature air, and thus potentially affecting the storage quality of other serum samples. This invention provides an animal serum sample storage device.

[0005] The purpose of this utility model is achieved through the following technical solution: an animal serum sample storage device, including a base, a cold storage chamber installed on the base, a refrigeration mechanism installed inside the base, the refrigeration mechanism being responsible for refrigerating the cold storage chamber, a rotatable rotating mounting frame installed inside the cold storage chamber, multiple sets of storage cavities arranged in a circular array on the rotating mounting frame, serum storage tubes placed in the storage cavities, and a servo motor installed inside the cold storage chamber, the power output end of the servo motor being connected to the middle of the rotating mounting frame;

[0006] A servo motor drives the rotating mounting frame to rotate, which in turn rotates the serum storage tubes placed on the mounting frame, making it easier to access the serum storage tubes.

[0007] The top of the cold storage compartment has an outlet hole with a diameter that matches the diameter of the serum storage tube. The inner bottom wall of the cold storage compartment is equipped with an electric push rod that matches the storage cavity. The telescopic end of the electric push rod is used to push the serum storage tube in the storage cavity out of the cold storage compartment through the outlet hole. A servo motor is set to control the rotation angle of the rotating mounting frame to be consistent each time, so that the serum storage tube on the rotating mounting frame can be accurately rotated to the top of the telescopic end of the electric push rod, thereby enabling the electric push rod to accurately push out the serum storage tube.

[0008] By using an electric push rod with a telescopic end, the serum storage tube placed in the storage chamber is pushed out through the outlet hole. The diameter of the outlet hole is matched with the diameter of the serum storage tube. As the cover of the serum storage tube is opened, the outer wall of the serum storage tube is in close contact with the inner wall of the outlet hole. This prevents the exchange of air between the outside and outside of the refrigerator during the opening of the cover, thus solving the problem of temperature fluctuations in the refrigerator during the process of retrieving the serum storage tube. This avoids damage to the low-temperature environment in the refrigerator, reduces the impact of temperature changes on the serum sample in the serum storage tube, and improves the storage quality of the serum storage tube in the refrigerator.

[0009] The top of the cold storage compartment is hinged with a cover plate corresponding to the outlet hole. The cover plate is made of metal. An electromagnet corresponding to the cover plate is installed on the outer ring of the outlet hole. The electromagnet is arranged in a ring. By setting the electromagnet corresponding to the outer ring of the outlet hole and the cover plate, the cover plate can be attracted when energized, thereby further improving the sealing effect of the cover plate on the outlet hole and ensuring the storage quality of the serum storage tube in the cold storage compartment.

[0010] A controller is installed on the base, which is electrically connected to the electromagnet, cooling mechanism, servo motor, and electric actuator. By setting the controller to be electrically connected to the electromagnet, cooling mechanism, servo motor, and electric actuator, it is convenient for operators to control the electromagnet, cooling mechanism, servo motor, and electric actuator through the controller, thus improving the ease of operation.

[0011] A further technical solution is that the refrigeration mechanism includes a compressor, which is connected in sequence to a condenser, an expansion valve, and an evaporator via a channel. The evaporator is located on the inner bottom wall of the cold storage compartment. The refrigeration compartment is cooled by the compressor, condenser, expansion valve, and evaporator within the refrigeration mechanism.

[0012] A further technical solution is to install a cooling fan corresponding to the condenser inside the base, and to install ventilation windows corresponding to the cooling fan on the side wall of the base. Dust filters are installed inside the ventilation windows. By setting up the cooling fan and ventilation windows in combination to exchange airflow, the equipment inside the base can quickly dissipate heat and ensure the stability of the refrigeration mechanism.

[0013] A further technical solution is that the inner wall of the refrigerator compartment is equipped with a sliding groove corresponding to the rotating mounting bracket, the outer wall of the rotating mounting bracket is equipped with a support disc that slides and connects with the sliding groove, and the inner wall of the sliding groove is equipped with ball bearings that connect with the support disc. The sliding groove and the ball bearings work together to provide stable support for the support disc on the rotating mounting bracket, while the ball bearings ensure the smoothness of the support disc during rotation.

[0014] A further technical solution involves placing the serum storage tube inside a storage cavity on a rotating mounting frame. The bottom of the storage cavity is equipped with multiple sets of circumferentially arrayed locking blocks. These blocks support the serum storage tube, ensuring smooth support without interfering with the extension and retraction of the electric push rod, allowing the extension and retraction of the electric push rod to smoothly eject the serum storage tube from the storage cavity.

[0015] A further technical solution is to have multiple sets of equidistant vents on the rotating mounting frame. By setting vents, the air circulation in the storage chamber is ensured, thereby ensuring that the serum storage tube on the rotating mounting frame is kept in a stable temperature environment.

[0016] A further technical solution is to install a temperature sensor inside the base that is electrically connected to the controller. By setting the temperature sensor, the controller can monitor the temperature inside the refrigerator. When the temperature inside the refrigerator exceeds the set range, the controller controls the refrigeration mechanism to cool the refrigerator, keeping the environment inside the refrigerator at the required temperature and ensuring that the storage environment of the serum storage tube is controllable.

[0017] A further technical solution is to install a display screen and a control panel on the controller. The display screen facilitates the acquisition of the equipment's operating parameters, while the control panel allows staff to easily control the controller, improving operational convenience.

[0018] This invention has the following advantages: By setting the telescopic end of the electric push rod, the serum storage tube placed in the storage chamber is pushed out through the outlet hole. The diameter of the outlet hole is adapted to the diameter of the serum storage tube. Thus, during the process of opening the cover of the serum storage tube, the outer wall of the serum storage tube is in close contact with the inner wall of the outlet hole, which can prevent the exchange of air between the outside and outside of the refrigerator during the opening of the cover. This solves the problem of temperature fluctuation in the refrigerator during the process of retrieving the serum storage tube, avoids damage to the low temperature environment in the refrigerator, reduces the impact of temperature changes on the serum sample in the serum storage tube, and improves the storage quality of the serum storage tube in the refrigerator.

[0030] like Figures 1-4 As shown, an animal serum sample storage device includes a base 1, a cold storage chamber 2 installed on the base 1, a refrigeration mechanism 9 installed inside the base 1, the refrigeration mechanism 9 being responsible for refrigerating the cold storage chamber 2, a rotatable rotating mounting frame 3 installed inside the cold storage chamber 2, multiple sets of storage cavities 4 arranged in a circular array on the rotating mounting frame 3, serum storage tubes 5 placed in the storage cavities 4, and a servo motor 12 installed inside the cold storage chamber 2, the power output end of the servo motor 12 being connected to the middle of the rotating mounting frame 3;

[0031] By setting a servo motor 12 to drive the rotating mounting frame 3 to rotate, the serum storage tube 5 placed on the rotating mounting frame 3 will rotate, making it easy to access the serum storage tube 5.

[0032] The top of the cold storage chamber 2 is provided with an outlet through hole 6, the diameter of which is adapted to the diameter of the serum storage tube 5. An electric push rod 13 adapted to the storage cavity 4 is installed on the inner bottom wall of the cold storage chamber 2. The telescopic end of the electric push rod 13 is used to push the serum storage tube 5 in the storage cavity 4 out of the cold storage chamber 2 through the outlet through hole 6. A servo motor 12 is provided to control the rotation angle of the rotating mounting frame 3 to be consistent each time, so that the serum storage tube 5 on the rotating mounting frame 3 can be accurately rotated to the top of the telescopic end of the electric push rod 13, so that the electric push rod 13 can accurately push out the serum storage tube 5. The outlet through hole 6 and the telescopic end of the electric push rod 13 are coaxially arranged, and the top of the cold storage chamber 2 can be provided with transparent glass to facilitate observation by the staff.

[0033] The serum storage tube 5 placed in the storage chamber 4 is pushed out through the outlet hole 6 by the telescopic end of the electric push rod 13. The diameter of the outlet hole 6 is matched with the diameter of the serum storage tube 5. Thus, when the cover plate 7 is opened, the outer wall of the serum storage tube 5 is in close contact with the inner wall of the outlet hole 6. This can prevent the exchange of air between the inside and outside of the cold storage chamber 2 during the opening of the cover plate 7. This solves the problem of temperature fluctuation in the cold storage chamber 2 during the process of taking out the serum storage tube 5, avoids damage to the low temperature environment in the cold storage chamber 2, reduces the impact of temperature changes on the serum sample in the serum storage tube 5, and improves the storage quality of the serum storage tube 5 in the cold storage chamber 2.

[0034] The top of the cold storage compartment 2 is hinged with a cover plate 7 corresponding to the outlet hole 6. The cover plate 7 is made of metal. An electromagnet 8 corresponding to the cover plate 7 is installed on the outer ring of the outlet hole 6. The electromagnet 8 is arranged in a ring. By setting the electromagnet 8 corresponding to the outer ring of the outlet hole 6, the cover plate 7 can be attracted when energized, thereby further improving the sealing effect of the cover plate 7 on the outlet hole 6 and ensuring the storage quality of the serum storage tube 5 in the cold storage compartment 2.

[0035] A controller 18 is installed on the base 1. The controller 18 is electrically connected to the electromagnet 8, the cooling mechanism 9, the servo motor 12, and the electric push rod 13. By setting the controller 18 to be electrically connected to the electromagnet 8, the cooling mechanism 9, the servo motor 12, and the electric push rod 13, it is convenient for the staff to control the electromagnet 8, the cooling mechanism 9, the servo motor 12, and the electric push rod 13 through the controller 18, thereby improving the convenience of operation.

[0036] The refrigeration mechanism 9 includes a compressor 901, which is connected in sequence to a condenser 902, an expansion valve 903, and an evaporator 904 via a channel. The evaporator 904 is located on the inner bottom wall of the refrigerator compartment 2. The compressor 901, condenser 902, expansion valve 903, and evaporator 904 in the refrigeration mechanism 9 are used to refrigerate the refrigerator compartment 2.

[0037] A cooling fan 10 corresponding to the condenser 902 is installed inside the base 1. An air exchange window 11 corresponding to the cooling fan 10 is installed on the side wall of the base 1. A dustproof net is installed inside the air exchange window 11. By setting the cooling fan 10 and the air exchange window 11 to cooperate in air exchange, the equipment inside the base 1 can be quickly cooled, ensuring the stability of the operation of the refrigeration mechanism 9.

[0038] The inner wall of the refrigerator compartment 2 is equipped with a slide groove 14 corresponding to the rotating mounting bracket 3. The outer wall of the rotating mounting bracket 3 is equipped with a support disc 301 that is slidably connected to the slide groove 14. The inner wall of the slide groove 14 is equipped with a ball bearing 15 that contacts the support disc 301. The slide groove 14 and the ball bearing 15 are designed to cooperate to provide stable support for the support disc 301 on the rotating mounting bracket 3. At the same time, the ball bearing 15 can ensure the smoothness of the rotation of the support disc 301.

[0039] The serum storage tube 5 is placed in the storage cavity 4 on the rotating mounting frame 3. Multiple sets of circumferentially arrayed locking blocks 401 are installed at the bottom of the storage cavity 4. The locking blocks 401 are responsible for supporting the serum storage tube 5. By setting the locking blocks 401, the support can be provided smoothly. At the same time, the locking blocks 401 will not interfere with the extension end of the electric push rod 13, so that the extension end of the electric push rod 13 can smoothly push the serum storage tube 5 out of the storage cavity 4.

[0040] The rotating mounting frame 3 has multiple sets of equidistant vent holes 16. By setting the vent holes 16, the air circulation in the storage cavity 4 is ensured, thereby ensuring that the serum storage tube 5 on the rotating mounting frame 3 is kept in a stable temperature environment.

[0041] A temperature sensor 17 electrically connected to the controller 18 is installed inside the base 1. By setting the temperature sensor 17, the controller 18 can monitor the temperature inside the refrigerator compartment 2. When the temperature inside the refrigerator compartment 2 exceeds the set range, the controller 18 controls the refrigeration mechanism 9 to work and refrigerate the refrigerator compartment 2, so that the environment inside the refrigerator compartment 2 is kept at the required temperature, ensuring that the storage environment of the serum storage tube 5 is controllable.

[0042] The controller 18 is equipped with a display screen 19 and a control panel 20.
