Technical Field

[0001] The utility model relates to the technical field of memories, and particularly to a cell cryopreservation solution memory. Background Art

[0002] A cryogenic fluid memory is a type of memory, which can be understood as a device for storing cryogenic liquid substances, similar to a cold storage liquid reservoir or a cryogenic storage tank. A cryogenic fluid memory can be regarded as a device specifically designed for storing, maintaining, and managing cryogenic liquid substances. These liquid substances may include liquid nitrogen, liquid oxygen, liquid argon, etc., which are widely used in multiple fields such as medicine, scientific research, and industry.

[0003] Cell cryopreservation is a crucial step in cell biology and medical research, which involves the long-term preservation and resuscitation of cells. Traditional cell cryopreservation solution formulations have problems such as low cell survival rate and decreased cell activity after resuscitation. Therefore, developing a new type of cell cryopreservation solution to improve the cryopreservation efficiency and post-resuscitation activity of cells has important practical application value.

[0004] A cell cryopreservation solution memory is a device that can maintain a specific low-temperature environment (such as -80°C, -196°C, etc.) for long-term storage of cell suspensions, which usually have been mixed with cell cryopreservation solution and subjected to appropriate cooling treatment.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-4 As shown, this embodiment discloses a cell cryopreservation liquid storage device, including a storage test tube 101, an outer shell 102, a fixing plate 105 and a clamping structure. The storage test tube 101 is used to store cell cryopreservation liquid. A box body 103 is arranged inside the outer shell 102, and a sealing cover 121 is also arranged inside the outer shell 102. An interlayer 104 is formed between the box body 103 and the outer shell 102, and the interlayer 104 is used to store a low-temperature medium. The fixing plate 105 is arranged inside the box body 103, and a support plate 106 is also arranged inside the box body 103. The storage test tube 101 is placed on the support plate 106, and the fixing plate 105 is used to clamp and fix the storage test tube 101. The clamping structure is arranged on the fixing plate 105 and is used to fixedly clamp the storage test tube 101.

[0030] The clamping structure includes a clamping block 107, a sliding rod 108 and a spring 109. A sliding groove 110 is provided on the fixed plate 105. Sliding holes 111 are provided on the inner walls of both sides of the sliding groove 110. The sliding rod 108 is slidably installed inside the sliding hole 111. The spring 109 is arranged in the sliding hole 111. One end of the spring 109 is connected to the bottom of the sliding hole 111, and the other end is connected to the sliding rod 108. The clamping block 107 is arranged at the end of the sliding rod 108. The clamping block 107 is slidably installed inside the sliding groove 110. The clamping block 107 is used to clamp the storage test tube 101.

[0031] The utility model mainly includes a storage test tube 101, a housing 102, a fixed plate 105 and a clamping structure. During actual use, the staff opens the housing 102 and inserts the storage test tube 101 containing cell cryopreservation solution into the fixed plate 105 until the storage test tube 101 contacts the support plate 106. During this process, the bottom surface of the storage test tube 101 contacts the clamping block 107. After squeezing the clamping block 107, the clamping block 107 drives the sliding rod 108 to slide inside the sliding hole 111. The sliding rod 108 squeezes the spring 109. As the storage test tube 101 is inserted, relative sliding occurs between the side wall of the storage test tube 101 and the clamping block 107. The reaction force of the spring 109 drives the clamping block 107 to clamp the storage test tube 101. At the same time, a low-temperature medium (liquid nitrogen) is introduced into the interlayer 104, so that the inside of the box body 103 always remains at a low temperature, which is beneficial to the preservation of the cell cryopreservation solution. When the storage test tube 101 needs to be taken out, only the storage test tube 101 needs to be pulled out. The advantage of this setting is that the storage test tube 101 is clamped and fixed through a simple clamping structure, and many storage test tubes 101 can be stored simultaneously in batches, which is convenient to take and has a low use cost.

[0032] In some embodiments, a limiting ring 112 is provided on the storage test tube 101. The limiting ring 112 is used to contact the fixed plate 105.

[0037] During actual use, the liquid inlet 114 is connected to a liquid nitrogen storage tank. When in use, the liquid outlet 115 is closed, then the liquid nitrogen in the liquid nitrogen storage tank is introduced into the interlayer 104, and finally the liquid inlet 114 is closed. The liquid nitrogen in the interlayer 104 refrigerates and stores the storage test tubes 101 inside the box body 103.

[0038] In some embodiments, a plurality of placement grooves 116 are arranged on the support plate 106, and the bottom of the storage test tube 101 is placed in the placement grooves 116.

[0039] During actual use, the purpose of arranging the placement grooves 116 is to enable surface contact between the bottom of the storage test tube 101 and the support plate 106, so that the storage test tube 101 can be installed more stably.

[0040] In some embodiments, the clamping block 107 interacts with the sliding groove 110 through a sliding component.

[0041] During actual use, using the sliding component can make the sliding between the clamping block 107 and the sliding groove 110 smoother.
