Description

Technical Field

[0001] The utility model relates to a cell storage device, in particular to a cell storage device for a biosafety sample library. Background Art

[0002] With the continuous in-depth development of biological science research in many fields such as molecular biology, gene editing, and disease mechanism exploration, as well as the widespread establishment of biological sample banks around the world, the importance of cell storage has become increasingly prominent. In the field of biological research, cell samples are key materials for exploring the mysteries of life, studying cell physiological functions and pathological mechanisms; in medical diagnosis, cell samples can be used for early detection of diseases, screening of diagnostic markers, etc.; in the biotechnology industry, cell samples also play an indispensable role in the development of emerging technologies such as biopharmaceuticals and cell therapy. Therefore, cell storage has become an important link in biological research, medical diagnosis, and the biotechnology industry.

[0003] In existing biosafety sample libraries, cell storage devices are responsible for preserving various precious cell samples, which may come from patients with rare diseases, individuals with special genetic backgrounds, or cell lines that have undergone complex genetic engineering. However, traditional cell storage devices have many shortcomings, especially in terms of safety.

[0004] Some traditional cell storage devices use a pull-out cell placement mechanism. Although this design facilitates the sample placement operation to a certain extent, it also has obvious safety hazards. For example, in a non-operating state, when the environment where the biosafety sample library is located is accidentally vibrated, such as the operation vibration of nearby equipment, the slight conduction of seismic waves, or the shaking during transportation, the pull-out cell placement mechanism may slide out due to the lack of sufficient fixing measures. In addition, improper human operation, such as accidentally colliding with the device, not operating in the correct order, etc., may also cause the same problem. Once the cell placement mechanism slides out, the cell sample container stored in it may fall or break, and the cell sample will be directly exposed to the external environment, the risk of contamination will increase sharply, and the sample may also be lost due to physical damage. This situation will destroy the cell samples that have been collected, processed and preserved with a lot of resources invested in the early stage, and will seriously affect the smooth progress of research based on these cell samples, such as delays in the progress of scientific research projects, inaccurate medical diagnosis results, and obstruction of biotechnology product development.

[0045] Open door 3:

[0046] Since the door body 3 and the cell storage box body 1 are hingedly connected, the user can open the door body 3 by rotating it, and then can access the pull-out cell placement mechanism 4 inside the cell storage box body 1.

[0047] Operation of the pull-out cell placement mechanism 4:

[0048] Pull out the middle placement plate 5: When the middle placement plate 5 is to be pulled out, first check whether the limit block 19 is in the limit state embedded in the limit frame 8. If it is in this state, rotate the handle bolt 14 to allow the stud part of the handle bolt 14 to move axially in the nut 13, thereby driving the wedge 16 to slide along the guide track 12. At this time, the slope surface of the wedge 16 moves forward, and the limit block 19 will move downward under the elastic force of the spring 21, and then disengage from the limit frame 8, releasing the limit state. Afterwards, the user holds the middle placement plate 5 and pulls it outward, and the rolling wheel 10 on the long support plate 9 will roll in the sliding track 7, making the pulling process smoother, until the middle placement plate 5 is pulled out to a suitable position for the storage or removal of cell samples.

[0049] Push back the middle placement plate body 5: After completing the operation on the cell sample, push the middle placement plate body 5 back into the cell storage box body 1. When pushing it back, the rolling wheels 10 roll in the sliding track 7 to ensure a smooth pushing-back operation. After the middle placement plate body 5 is pushed into place, rotate the handle bolt 14 in the reverse direction, causing the wedge block 16 to slide in the reverse direction. The ramp surface of the wedge block 16 will push the limit block 19 to move upward against the elastic force of the spring 21 and re-embed it into the limit frame body 8 to limit the middle placement plate body 5 and prevent it from accidentally sliding out.

[0050] Close the door body 3:

[0051] After completing the operation on the pull-out type cell placement mechanism 4, the user rotates the door body 3 to close the front opening of the cell storage box body 1, ensuring that the inside of the cell storage box body 1 is in a closed state and protecting the storage environment of the cell sample from external interference.

[0052] Enhanced safety: Inside this device, a structure combining the limit block 19 and the limit frame body 8 is carefully designed. The limit block 19 and the limit frame body 8 cooperate with each other, just like an accurate lock and key. When the pull-out type cell placement mechanism 4 is in a non-operating state, it can strongly prevent it from accidentally sliding out. In the environment of a biobank, various unexpected situations may occur, such as the device being slightly bumped or the vibration of the surrounding environment. Without this effective limit design, the pull-out type cell placement mechanism 4 may suddenly slide out, putting the cell samples stored in it at great risk. And this design ensures that the samples are always in a safe storage state, providing a reliable guarantee for the safe preservation of cell samples.

[0053] Improved reliability: The combined design of the spring 21 and the limit block 19 in the device is a key factor in improving the system reliability. During daily use, the biobank may be subject to external impacts, such as jolts during handling or vibration interference generated by other large instruments running near the device. When an external impact acts on the device, this combined design can effectively prevent the pull-out type cell placement mechanism 4 from loosening. The spring 21 can adaptively adjust the state of the limit block 19 according to the external impact situation, always maintaining stable limitation on the pull-out type cell placement mechanism 4, further enhancing the reliability of the entire system in a complex environment and ensuring the stability and safety of the cell sample storage process.

[0054] Operational convenience: The design of the pull-out cell placement mechanism 4 greatly improves the operational convenience. For users, when they need to access cell samples, they can easily pull out or push back the middle placement plate body 5. This operation process is very simple, and during the entire operation process, rotating the handle bolt 14 to control the lifting of the limit block 19 plays an important role in simplifying the operation. When pulling out the middle placement plate body 5, rotate the handle bolt 14 to lower the limit block 19 to release the limit, and then it can be smoothly pulled out; after pushing back the middle placement plate body 5, rotate the handle bolt 14 again to raise the limit block 19 for limiting. This design makes the operation process clear and simple, reduces the complexity of the operation, and improves the efficiency and accuracy of user operation.

[0055] Improved stability: The stability of the device benefits from the combined use of the rolling wheels 10 provided on the long strip support plate body 9 and the sliding track 7. During the pull-out process, the rolling wheels 10 roll along the sliding track 7. This rolling friction method has a smaller frictional force compared to other friction methods. This enables the pull-out process to proceed smoothly without obstruction, just as smoothly as a train running on a railway track. This smooth pull-out not only improves the operational comfort but, more importantly, improves the overall stability of the device. Moreover, the stable pull-out process also reduces the wear between the components of the device, thereby enhancing the durability of the device, enabling the device to always maintain good performance during long-term use, and providing strong support for the long-term stable storage of cell samples.

[0056] High space utilization rate: The layout of the pull-out cell placement mechanism 4 in the cell storage box 1 is evenly arranged from the upper part to the lower part. This design cleverly utilizes the vertical space of the cell storage box 1. In a biosafety sample library, space resources are very precious. Through this reasonable layout, more cell samples can be stored in a limited space. Compared with traditional layout methods, this design avoids waste of space, realizes the efficient storage of cell samples, improves the space utilization efficiency of the entire cell storage device, and meets the needs of the biosafety sample library for storing a large number of cell samples.

[0057] The above describes the present utility model and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present utility model, design similar structural methods and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
