Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical storage technology, specifically to an antibody refrigeration device. Background Technology

[0002] Antibodies are special proteins with biological activity, widely used in biomedical research, clinical diagnosis, and treatment. Their activity is highly susceptible to environmental factors such as temperature, vibration, and contamination, thus requiring specialized refrigeration equipment to maintain their biological activity and stability. Antibody refrigeration equipment, as key equipment in laboratories, medical institutions, and the biopharmaceutical field, primarily achieves safe storage of antibody samples through a stable low-temperature environment (such as 2-8℃, -20℃, etc.), reliable sealing performance, and anti-shake structures. This is a crucial foundation for ensuring the accuracy of experimental results and the effectiveness of clinical applications.

[0003] Existing antibody refrigeration devices still have shortcomings in practical use: On the one hand, traditional devices often use rigid slots to fix test tubes, which are difficult to adapt to antibody test tubes of different sizes and lack stability. When moved or vibrated, the test tubes are prone to shaking, collision, or even breakage and leakage, affecting antibody safety. On the other hand, most devices adopt an integrated sealed structure. When a single or a few antibody test tubes need to be retrieved, the entire chamber door must be opened, resulting in a large loss of internal cold air and large temperature fluctuations. This not only affects the storage environment of other unretrieved antibodies but also increases the energy consumption of the refrigeration module. Furthermore, poor sealing can lead to the intrusion of external microorganisms or abnormal internal humidity, increasing the risk of antibody contamination. At the same time, poor internal refrigeration circulation may cause uneven local temperature, further affecting the maintenance of antibody activity. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing an antibody refrigeration device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an antibody refrigeration device, including a device shell, a refrigeration module is provided at the bottom inside the device shell, a storage mechanism is provided inside the device shell, and a sealing mechanism is provided above the storage mechanism; The storage mechanism includes a mounting base, several elastic clamping structures, several bottom limiting structures, and several test tube bodies. The mounting base is provided with several elastic clamping structures inside, and the bottom of each of the several elastic clamping structures is provided with a bottom limiting structure. Each of the several elastic clamping structures is provided with a test tube body inside. The sealing mechanism includes a sealing isolation seat and several sealing cover plate structures. The sealing isolation seat is fixedly installed inside the device housing and located above the storage mechanism. Several sealing cover plate structures are threadedly connected to the top of the sealing isolation seat.

[0006] The mounting base integrates multiple flexible clamping structures and a bottom limiting structure, which can store multiple antibody tubes at the same time to meet the needs of batch refrigeration. Moreover, through the adaptive design of the flexible clamping, it can be compatible with antibody tubes of different specifications (such as centrifuge tubes or cryopreservation tubes of different lengths and diameters) without changing accessories, reducing the device's dependence on specific tubes and improving its versatility and ease of use in laboratories, medical institutions and other scenarios.

[0007] Furthermore, the elastic clamping structure includes a test tube storage cavity. Mounting grooves are provided on both side walls of the test tube storage cavity. Several sliding guide grooves are provided on the front and back side walls of the two mounting grooves. Sliding guide blocks are provided at the connection points of the sliding guide grooves. A connecting plate is provided at the connection point of several sliding guide blocks on one side. Two triangular clamping seats are provided at the connection points of the four connecting plates. When the sliding guide blocks slide along the sliding guide grooves, the connecting plates can drive the two triangular clamping seats to open and close, allowing the elastic clamping structure to adapt to test tubes of different diameters, improving its adaptability to antibody test tubes of different specifications. Simultaneously, the structural design of the triangular clamping seats enhances the clamping stability of the test tubes.

[0008] Furthermore, the top of the mounting base is provided with upper and lower ventilation slots on both sides. The test tube body is clamped between the two triangular clamping seats. The sliding guide block is slidably connected to the sliding guide slot. The sliding guide block, connecting plate and triangular clamping seats are integrated into one piece. The upper and lower ventilation slots can promote the vertical circulation of cold air inside the device, avoid uneven local temperature, and ensure that all test tubes are in a uniform low temperature environment. The sliding connection between the sliding guide block and the sliding guide slot makes the clamping structure open and close more smoothly. The integrated design improves the structural strength of the sliding guide block, connecting plate and triangular clamping seats, reduces the risk of component loosening, and extends service life.

[0009] Furthermore, the bottom limiting structure includes a supporting limiting plate, the bottom of which has several ventilation holes. The supporting limiting plate is fixedly connected to the mounting base. The supporting limiting plate limits the bottom of the test tube body to prevent the test tube from sinking or tipping over due to improper clamping. The ventilation holes allow cold air to circulate from the bottom to the surrounding area of ​​the test tube, ensuring that the temperature at the bottom and top of the test tube is consistent, further improving temperature uniformity.

[0010] Furthermore, the top of the sealing isolation seat is provided with several connecting grooves, and the outer side of each of the connecting grooves is provided with a sealing thread groove. The connecting grooves provide operating space for the test tube body to be picked up and put down, making it convenient for users to quickly pick up the target test tube. The sealing thread grooves provide threaded connection points for the sealing cover structure, and the sealing performance is enhanced by the threaded engagement, reducing the loss of cold air when picking up and putting down a single test tube.

[0011] Furthermore, the sealing cover structure includes a sealing cover with connecting threads on its outer wall and a rotating block on its top. The connecting threads and the sealing thread groove cooperate to achieve a tight screw-on of the sealing cover, effectively blocking the entry of external hot air and the overflow of internal cold air. The rotating block allows the user to manually rotate the sealing cover, improving the ease of operation when taking out and putting in test tubes and reducing the difficulty of operation.

[0012] Furthermore, the connecting groove facilitates the handling of the test tube body, the connecting thread is threadedly connected to the sealing thread groove, and the rotating block is used to manually rotate the sealing cap. The connecting groove directly improves the convenience of handling the test tube and avoids interference with other test tubes during handling. The threaded connection between the connecting thread and the sealing thread groove ensures the sealing reliability of the sealing cap and reduces cold loss. The rotating block simplifies the opening and closing operation of the sealing cap, making the handling of a single test tube more efficient, while reducing temperature fluctuations caused by improper operation.

[0013] Furthermore, the front of the device housing is equipped with a controller, and the top of the device housing is hinged with a sealing cover. The controller can precisely adjust the operating parameters of the refrigeration module (such as temperature setting, refrigeration power, etc.) to achieve precise control of the storage temperature. The top sealing cover and the sealing mechanism form a double seal, further blocking the influence of the external environment, reducing the loss of cold energy, and providing additional protection for the internal structure of the device.

[0014] The beneficial effects of this utility model are as follows: through the sliding cooperation between the sliding guide block and the sliding guide groove in the elastic clamping structure, the triangular clamping seat can be opened and closed flexibly, which can be adapted to test tube bodies of different diameter specifications. Moreover, the clamping structure of the triangular clamping seat can form a stable fixation for the test tube. Combined with the support limiting plate of the bottom limiting structure, the bottom of the test tube is limited, which effectively avoids the shaking, collision or even tipping of the test tube when it is moved or vibrated, thus improving the safety of antibody test tube storage.

[0015] The sealing mechanism adopts a combination design of a sealing isolation seat and several independent sealing cover plates. When it is necessary to take out a single or a few test tubes, only the corresponding sealing cover plate needs to be unscrewed. There is no need to open the overall door of the device, which greatly reduces the loss of internal cold air, reduces temperature fluctuations caused by taking out and putting out operations, ensures the stability of the storage environment for unused antibodies, and reduces the energy consumption of the refrigeration module.

[0016] The upper and lower ventilation slots on the top of the mounting base promote the circulation of cold air inside the device, while the ventilation holes supporting the limiting plate in the bottom limiting structure allow cold air to flow from the bottom to the area around the test tube. The combination of these two features ensures that the cold air inside the device is evenly distributed, avoiding the impact of local temperature differences on antibody activity.

[0017] The sealing cover structure is connected to the sealing groove of the sealing isolation seat by connecting threads, forming a tight seal, reducing the intrusion of external air and microorganisms. At the same time, in conjunction with the overall sealing design of the device, it effectively reduces the risk of antibody contamination and ensures the cleanliness of antibody storage.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0022] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] Example 1 Figure 1 This is a structural diagram of the main body of this utility model. Figure 2 This is a structural diagram of the internal structure of the device housing of this utility model. Figure 3 This is a schematic diagram of the sealing mechanism of this utility model. Figure 4 This is a top view schematic diagram of the elastic clamping structure of this utility model. Figure 5 This is a bottom view of the bottom limiting structure of this utility model. Figure 6 This is a cross-sectional view of the main body of this utility model, as shown below. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the device includes a housing 10, a cooling module 40 is provided at the bottom inside the housing 10, a storage mechanism 50 is provided inside the housing 10, and a sealing mechanism 60 is provided above the storage mechanism 50. The outer casing 10 forms a closed storage space, providing physical protection for the internal structure and reducing interference from the external environment. After the cooling module 40 is started, it generates cold energy through a cooling cycle to maintain the low-temperature environment required for antibody preservation inside the outer casing 10. The storage mechanism 50 is used to position the antibody tubes in an orderly manner in this low-temperature environment to prevent the tubes from shaking randomly. The sealing mechanism 60 forms a sealing barrier above the storage mechanism 50 to reduce the diffusion of internal cold energy to the outside, while blocking external heat and contaminants from entering. The four components work together to construct a stable antibody cryopreservation system.

[0024] like Figures 4 to 6 As shown, the storage mechanism 50 includes a mounting base 501, several elastic clamping structures, several bottom limiting structures, and several test tube bodies 508. The mounting base 501 is provided with several elastic clamping structures inside, and the bottom of each of the several elastic clamping structures is provided with a bottom limiting structure. Each of the several elastic clamping structures is provided with a test tube body 508 inside. Mounting base 501 serves as the basic load-bearing structure, providing a fulcrum for the fixed installation of the elastic clamping structure and the bottom limiting structure, ensuring the stability of each structure's position. The elastic clamping structure clamps the test tube body 508 from the side using its adjustable clamping force, adapting to the fixing needs of test tubes of different specifications. The bottom limiting structure provides support and limitation from the bottom of the test tube, preventing the test tube from moving excessively or tipping over in the vertical direction. The three components work together to keep the test tube body 508 stable during storage, avoiding collisions and damage to the test tubes caused by device movement or vibration.

[0025] The elastic clamping structure includes a test tube storage cavity 502. Mounting grooves 503 are provided on both sides of the inner wall of the test tube storage cavity 502. Several sliding guide grooves 504 are provided on the front and back side walls of the two mounting grooves 503. Sliding guide blocks 505 are provided at the connection points of the sliding guide grooves 504. A connecting plate 506 is provided at the connection point of several sliding guide blocks 505 on one side. Two triangular clamping seats 507 are provided at the connection points of the four connecting plates 506.

[0026] The test tube storage cavity 502 provides space for the test tubes, and the mounting groove 503 provides mounting positions for components such as the sliding guide groove 504 and the sliding guide block 505. When the test tube is placed in the test tube storage cavity 502, the outer wall of the test tube will press against the two triangular clamping seats 507. After being subjected to force, the triangular clamping seats 507 drive the sliding guide block 505 to slide along the sliding guide groove 504 into the mounting grooves 503 on both sides through the connecting plate 506. By utilizing the elastic restoring force of the structure itself, the two triangular clamping seats 507 are always tightly attached to the outer wall of the test tube, thereby achieving adaptive clamping and fixing of test tubes of different diameters and ensuring clamping stability.

[0027] The top of the mounting base 501 is provided with upper and lower ventilation slots 511 on both sides. The test tube body 508 is clamped between the two triangular clamping seats 507. The sliding guide block 505 is slidably connected to the sliding guide groove 504. The sliding guide block 505, the connecting plate 506 and the triangular clamping seats 507 are designed as an integral unit.

[0028] The upper and lower ventilation slots 511 connect the upper and lower spaces of the mounting base 501, allowing the cold air generated by the cooling module 40 to flow upward from the bottom of the device, while simultaneously circulating the upper cold air downward, ensuring uniform temperature in the test tube storage area; the sliding connection between the sliding guide block 505 and the sliding guide groove 504 provides guidance for the opening and closing of the triangular clamping base 507, ensuring smooth and stable clamping action and avoiding jamming; the integrated design of the sliding guide block 505, the connecting plate 506, and the triangular clamping base 507 enhances the overall rigidity of the structure, reduces gaps and looseness between components, ensures stable transmission of clamping force, and extends the service life of the structure.

[0029] The bottom limiting structure includes a support limiting plate 509, and the bottom of the support limiting plate 509 is provided with several ventilation holes 510. The support limiting plate 509 is fixedly connected to the mounting base 501.

[0030] The support limiting plate 509 is fixed on the mounting base 501, forming a support from the bottom of the test tube and limiting the excessive sinking of the test tube in the vertical direction. At the same time, it works with the elastic clamping structure to fix the test tube from the side, preventing the test tube from tilting or tipping over. The ventilation hole 510 allows the cold air generated by the cooling module 40 to pass through the bottom of the support limiting plate 509 and enter the lower space of the test tube storage cavity 502. It works with the upper and lower ventilation slots 511 to form a complete cold air circulation path, ensuring that the temperature of the bottom and upper surroundings of the test tube is consistent, and avoiding local temperature differences from affecting antibody activity.

[0031] like Figure 3 As shown, the top of the sealing isolation seat 601 is provided with several connecting grooves 602, and the outer side of each of the several connecting grooves 602 is provided with a sealing thread groove 603.

[0032] The opening of the connecting groove 602 provides an operating channel for taking out test tubes, making it convenient for fingers or tools to reach in and put out test tubes, avoiding contact with other test tubes during the process; the sealing thread groove 603 matches the connecting thread 605 of the sealing cover plate 30 structure, and the threaded engagement allows the sealing cover plate 30 to tightly cover the connecting groove 602, forming a mechanical seal, effectively preventing the internal cold energy of the device from leaking out from the connecting groove 602, while also blocking external air and pollutants from entering the test tube storage area through the connecting groove 602.

[0033] The sealing cover plate 30 structure includes a sealing cover 604, the outer wall of the sealing cover 604 is provided with connecting threads 605, and the top of the sealing cover 604 is provided with a rotating block 606.

[0034] The sealing cover 604 engages with the sealing thread groove 603 of the sealing isolation seat 601 via the connecting thread 605 on its outer wall. The helical structure of the thread creates a tight fit between the sealing cover 604 and the sealing isolation seat 601, enhancing the sealing effect and reducing cold loss. The rotating block 606 increases the contact area between the hand and the sealing cover 604, making it easier for the operator to tighten or loosen the sealing cover 604 by rotating the rotating block 606. This makes the opening and closing of a single connecting groove 602 more convenient and effortless. Furthermore, the independent sealing cover plate 30 design ensures that when a single connecting groove 602 is opened, the other connecting grooves 602 remain sealed, preventing overall cold loss.

[0035] The connecting groove 602 is used to facilitate the removal of the test tube body 508. The connecting thread 605 is threadedly connected to the sealing thread groove 603. The rotating block 606 is used to manually rotate and drive the sealing cover 604 to rotate.

[0036] The connecting groove 602 directly provides operating space for the handling of test tubes, allowing operators to directly contact the test tubes and remove or place them, simplifying the operation process. The threaded connection between the connecting thread 605 and the sealing thread groove 603 achieves a tight connection between the sealing cap 604 and the sealing isolation seat 601 through helical engagement. The self-locking property of the thread ensures a stable sealing state and prevents loosening. The rotating block 606 serves as the point of force application. Manual rotation can drive the sealing cap 604 to rotate synchronously, enabling the sealing cap 604 to open and close quickly. This ensures that other areas remain well-sealed during the handling of a single test tube, reducing temperature fluctuations.

[0037] Example 2 Based on the above embodiments, this embodiment also makes the following improvements, such as... Figure 1 As shown, the front of the device housing 10 is also provided with a controller 20, and the top of the device housing 10 is hinged with a sealing cover 30.

[0038] The controller 20 can receive feedback signals from the temperature sensor and stabilize the internal temperature of the device within the set antibody preservation temperature range by adjusting the operating status of the cooling module 40 (such as start / stop and power adjustment), thus achieving precise temperature control. The sealing cover 30 on the top of the device shell 10 can be opened and closed flexibly through a hinge structure. When closed, it fits tightly with the device shell 10 to form an outer seal. Combined with the inner seal of the sealing mechanism 60, it further enhances the overall sealing performance and reduces cold loss. When open, it facilitates overall maintenance, cleaning, or batch handling of test tubes inside the device, improving operational convenience.

[0039] Workflow Start-up preparation phase Close the sealing cover 30 on the top of the device housing 10 to form an outer seal with the housing; set the required storage temperature for the antibody (e.g., 2-8℃ or -20℃) through the front controller 20, and send a command to the cooling module 40. The cooling module 40 starts and begins to cool, and the cold energy gradually diffuses inside the device housing 10 until the set temperature is reached.

[0040] Antibody storage stage To store antibody test tubes, first open the sealing cover 30 at the top of the device housing 10 to expose the sealing isolation seat 601; by rotating the rotating block 606 of the sealing cover 30 structure, loosen and remove the sealing cover 604 above the corresponding connecting groove 602 to expose the connecting groove 602; place the test tube body 508 containing antibodies from the connecting groove 602 into the test tube storage cavity 502 below, with the bottom of the test tube contacting the support limiting plate 509 of the bottom limiting structure (achieving bottom limiting), while the outer wall of the test tube is squeezed and elastically clamped. The two triangular clamping seats 507 of the structure force the triangular clamping seats 507 to drive the sliding guide block 505 to slide to both sides along the sliding guide groove 504 through the connecting plate 506. The elastic restoring force of the structure makes the triangular clamping seats 507 tightly fit the outer wall of the test tube (achieving side clamping and fixation). After the test tube is placed stably, the rotating block 606 is rotated in the opposite direction to screw the sealing cover 604 into the sealing thread groove 603 through the connecting thread 605, close the connecting groove 602, and finally cover the sealing cover plate 30 on the top of the device housing 10.

[0041] Low-temperature storage stage The refrigeration module 40 operates continuously, and the generated cold air flows upward through the upper and lower ventilation slots 511 on the top of the mounting base 501. At the same time, it enters the lower part of the test tube storage cavity 502 through the ventilation holes 510 at the bottom of the support limiting plate 509, forming a cold air circulation to ensure uniform temperature inside the device (including around the test tubes). The sealing cover 604 of the sealing mechanism 60 is tightly fitted to the sealing isolation seat 601 by threads, and together with the sealing cover plate 30 on the top of the device shell 10, a double seal is formed to reduce the loss of cold air to the outside. The elastic clamping structure and the bottom limiting structure work together to ensure that the test tubes remain stable when the device moves or vibrates slightly, avoiding collisions.

[0042] antibody collection stage To use a specific antibody tube, open the sealing cover 30 at the top of the device housing 10, locate the corresponding tube's connection slot 602, rotate the sealing cover 604 rotating block 606 above the connection slot 602, loosen and remove the sealing cover 604; grasp the tube body 508 through the connection slot 602 and lift it upwards. At this time, the triangular clamping seat 507 of the elastic clamping structure, due to the loss of tube compression, will reset along the sliding guide slot 504 via the sliding guide block 505 under its own elasticity; after use, place the new tube in (or leave it empty), tighten the sealing cover 604, and close the sealing cover 30 at the top of the device housing 10.

[0043] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
