Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of freezing tubes, and specifically relates to an embryo freezing tube. Background Technique
[0002] An embryo freezing tube is a container specifically used for freezing and storing embryos. It is usually made of high-quality plastic or glass materials and has good sealing performance and low-temperature resistance. The design of the embryo freezing tube aims to provide a safe and stable environment for embryos so that they can be successfully resuscitated and used in assisted reproductive technology when needed. For some cancer patients who need radiotherapy and chemotherapy, or those who need to postpone childbearing for other reasons, the embryo freezing tube can preserve their fertility.
[0003] In traditional embryo freezing tubes, the carrier rod is usually directly fixedly installed inside the freezing tube. During the transportation of the freezing tube, it is easy to shake. The shaking may cause the embryo to collide with the inner wall of the freezing tube or the carrier rod, resulting in mechanical damage to the fragile embryo cells. This kind of damage may affect the developmental potential of the embryo and reduce the survival rate and implantation rate after embryo resuscitation. Content of the Utility Model
[0004] To solve the problems raised in the above background technique, the utility model provides an embryo freezing tube, which solves the problem of inconveniently ensuring the stability of embryo transportation.

[0006] Each of the two groups of stabilizing mechanisms includes a clamping block, a pulling rod, a limiting spring and a limiting block. The number of each clamping block, pulling rod, limiting spring and limiting block is set to two. The two pulling rods are fixedly connected to one side of the two clamping blocks. The two limiting springs are sleeved on the surfaces of the two pulling rods, and the two limiting blocks are slidably connected to the two pulling rods.
[0007] Preferably, a grip rod is fixedly connected to the bottom end of the storage tube, and a groove is provided on the outer surface of the bottom end of the storage tube.

[0012] Preferably, one ends of the two limit springs are fixedly connected to the two clamping blocks, and the other ends of the two limit springs are fixedly connected to the inner side wall of the storage tube.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figures 1 to 4 shown, the present utility model provides an embryo cryopreservation tube, which includes a storage tube 1. A fixed cover 2 is provided at the top of the storage tube 1. A carrier rod 3 is provided inside the storage tube 1. Stable mechanisms 4 are installed on both sides of the storage tube 1. There are two groups of stable mechanisms 4, and the carrier rod 3 is located between the two groups of stable mechanisms 4;
[0022] Both groups of stable mechanisms 4 include clamping blocks 41, pulling rods 42, limiting springs 43 and limiting blocks 44. The number of each group of clamping blocks 41, pulling rods 42, limiting springs 43 and limiting blocks 44 is set to two. The two pulling rods 42 are fixedly connected to one side of the two clamping blocks 41. The two limiting springs 43 are sleeved on the surfaces of the two pulling rods 42. The two limiting blocks 44 are slidably connected to the two pulling rods 42.
[0023] Adopting the above scheme: The storage tube 1 is the main structure of the entire embryo cryopreservation tube, providing a safe and sealed space for the storage of embryos. The material of the storage tube 1 is usually carefully selected, which can effectively resist external physical impacts, temperature changes and other adverse factors, providing reliable physical protection for the embryos.
[0024] As Figures 1 to 4 shown, a grip rod 101 is fixedly connected to the bottom end of the storage tube 1. A groove is provided on the outer surface of the bottom end of the storage tube 1. A through hole is provided on the surface of the fixed cover 2. A card slot is provided on the outer surface of the top end of the storage tube 1. Card blocks 21 are slidably connected to both sides of the fixed cover 2, and the card blocks 21 are adapted to the card slots.
[0025] Adopting the above scheme: A groove is provided at the tail of the storage tube 1 for pasting a label for identifying embryo information. The carrier rod 3 at the part for placing embryos at the head of the storage tube 1 is set as a flat transparent slide, which can reduce the amount of culture medium liquid carried during vitrification cryopreservation operation, improve the success rate of embryo cryopreservation. The flat transparent carrier rod 3 is marked to help the cryopreservation operator and the thawing operator locate the position of the embryo. The through hole on the fixed cover 2 ensures the contact between liquid nitrogen and the embryo, preventing the air in the fixed cover 2 from causing the cryopreservation carrier rod 3 to float, and can prevent the embryo from slipping and being lost due to jolting during storage.
[0026] As Figures 1 to 4As shown in the figure, holes adapted to the clamping blocks 21 are provided inside both sides of the fixed cover 2. The number of holes and clamping blocks 21 is set to two. One end of each of the two pull rods 42 is fixedly connected to a knob 421. The outer surfaces of the two pull rods 42 near the knobs 421 are fixedly connected with sliders 422. Both of the two limit blocks 44 are fixedly connected with fixed blocks 45 through fixing pieces. A sliding groove adapted to the slider 422 is provided inside the fixed block 45. One end of each of the two limit springs 43 is fixedly connected to one of the two clamping blocks 41, and the other end of each of the two limit springs 43 is fixedly connected to the inner side wall of the storage tube 1.
[0027] Adopting the above solution: The carrier rod 3 carries the embryo and provides a specific placement position for the embryo. Its design usually takes into account the size, shape of the embryo and the special requirements of cryopreservation to ensure that the embryo can be stably placed on the carrier rod 3 and will not be damaged due to shaking or other factors. The embryo can be in contact with liquid nitrogen because liquid nitrogen is widely used in the field of reproductive medicine for freezing and storing embryos, eggs and sperm. In in vitro fertilization (IVF) technology, embryos are usually frozen in a specific freezing medium and then placed in a liquid nitrogen tank to maintain a low temperature, thereby slowing down cell metabolism and biochemical reactions, enabling the long-term preservation of embryos. However, this process requires strict operating procedures and professional equipment to ensure the safety of embryos during freezing and thawing. An improper freezing or thawing process may cause damage to the embryo, affecting its survival rate and implantation success rate. Therefore, when performing embryo freezing and storage, it is necessary to follow the advice and guidance of professional doctors.
[0028] The working principle and usage process of the present utility model: Check whether all components of the embryo freezing tube are intact, including the storage tube 1, the fixed cover 2, the carrier rod 3, the stabilizing mechanism 4, etc. Ensure that the clamping blocks 21 on both sides of the fixed cover 2 are in a slidable state and can cooperate with the card slots at the top of the storage tube 1 for fixation. Check whether the clamping blocks 41 of the stabilizing mechanism 4 are in a loosened state and whether the knobs 421 on the pull rods 42 can be normally operated. Pull the knobs 421 at one end of the two pull rods 42 to move the clamping blocks 41 to both sides, compressing the limit springs 43. Place the carrier rod 3 into the storage tube 1 at the middle position between the two stabilizing mechanisms 4. Slowly release the knob 421. Under the action of the limit springs 43, the clamping blocks 41 move towards the carrier rod 3 to clamp the carrier rod 3 to ensure its stability. Place the embryo on the carrier rod 3;
[0029] Align the fixed cover 2 with the top of the storage tube 1 so that the clamping blocks 21 can slide into one end of the card slot. Rotate the storage tube 1 so that the clamping blocks 21 move along the arc end of the card slot to the other end until the clamping blocks 21 slide to the other end of the card slot. Push the clamping blocks 21 on both sides of the fixed cover 2 inward to make them snap into the card slots on the outer surface of the top of the storage tube 1 to ensure that the fixed cover 2 is firmly fixed. Place the freezing tube containing the embryo into the freezing equipment for cryopreservation;
[0030] When it is necessary to take out the carrier rod 3, operate the clamping block 21 and the storage tube 1 in the reverse direction, open the fixed cover 2, remove it from the top of the storage tube 1, pull the knob 421 at one end of the pull rod 42 to make the clamping block 41 release the carrier rod 3, and carefully take out the carrier rod 3 to complete the operation.
[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
