Description

Technical Field

[0001] This utility model relates to the field of biomedical engineering technology, specifically to a sperm cryopreservation, transport, and storage device. Background Technology

[0002] Sperm are the reproductive cells of the male reproductive system and a crucial component of fertilization. A sperm is a single-celled mitotic organism, typically elongated and curved. It consists of a head, neck, and tail. The head contains the nucleus and acrosome, which plays a vital role in the fertilization process. The neck connects the head and tail, and the tail is the sperm's motility organ, helping it swim to the egg. Sperm production and development occur in spermatogonia within the male testes. Through a series of cell divisions and differentiations, spermatogonia gradually develop into sperm. This process is called spermatogenesis. The primary function of sperm is fertilization. Once sperm enter the female reproductive tract, they swim forward, passing through the cervix and uterus, eventually reaching the fallopian tubes. Inside the fallopian tubes, sperm combine with the released egg to complete fertilization, forming a zygote. During each ejaculation, an adult male typically releases millions to billions of sperm. However, only a small fraction of these sperm successfully fertilize an egg. Sperm motility and vitality are essential for successful fertilization. Sperm can be preserved and stored using cryopreservation technology. This allows men to use frozen sperm samples in assisted reproductive technologies, such as in vitro fertilization (IVF) or artificial insemination, when needed. In short, sperm are the reproductive cells in the male reproductive system, possessing the ability to swim and fertilize, and play a vital role in human reproduction and propagation.

[0003] Currently, in existing technologies, when using sperm cryopreservation and storage devices, the devices are generally large and difficult to move. Moreover, the devices may shake during transport, and excessive shaking can lead to a decrease in sperm motility. Therefore, this invention proposes a sperm cryopreservation and storage device. Utility Model Content

[0004] In addressing the shortcomings of existing sperm cryopreservation and storage devices, which are often bulky and difficult to move, and prone to shaking during transport, leading to a decrease in sperm motility due to excessive shaking, this invention provides a sperm cryopreservation and storage device that reduces the degree of shaking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sperm cryopreservation, transport, and storage device includes a cryopreservation container. A fifth fixing plate is fixedly connected inside the cryopreservation container. A sample box is slidably connected to one side of the fifth fixing plate. A fourth fixing plate is fixedly connected to the bottom of the sample box. A third fixing block is fixedly connected to the bottom of the fourth fixing plate.

[0010] Preferably, the size of the opening of the groove is adapted to the size of the first fixing rod, so that the first fixing rod can be better fixed, thereby better fixing the whole, and the number of grooves is multiple and evenly distributed.

[0011] Beneficial effects: 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1-4 A sperm cryopreservation, transport, and storage device includes a cryopreservation container 1. A fifth fixing plate 12 is fixedly connected inside the cryopreservation container 1. A sample box 6 is slidably connected to one side of the fifth fixing plate 12. A fourth fixing plate 11 is fixedly connected to the bottom of the sample box 6. A third fixing block 20 is fixedly connected to the bottom of the fourth fixing plate 11. A shock-absorbing mechanism is provided on the outside of the third fixing block 20. The shock-absorbing mechanism includes a third fixing rod 21, a fourth fixing rod 23, a fixing ring 13, and a fourth spring 22. A second fixing plate 9 is fixedly connected to one side of the fourth fixing rod 23. Fixed plate 9 and freezing container 1 are fixedly connected. Fixed plate 10 is slidably connected to one side of freezing container 1. An adjustment mechanism is provided on the outside of fixed plate 10. The adjustment mechanism includes groove 19, fixed block 18, spring 14 and fixed rod 16. Fixed rod 17 is fixedly connected to one side of fixed plate 10.

Fixed plate 3 is rotatably connected inside freezing container 1.

[0017] Working principle: When the device is needed, open the first fixing plate 3, place the collected sperm in the sample box 6, close the first fixing plate 3, pull the first fixing rod 16 so that the first fixing rod 16 can drive the second fixing block 18 to move. At this time, the third spring 14 generates a force due to compression until the first fixing rod 16 is completely removed from the groove 19. Stop pulling the first fixing rod 16, move the third fixing plate 10 so that the third fixing plate 10 drives the roller 2 to the appropriate position, and slowly release the first fixing rod 16. The first fixing rod 16 will drive the second fixing block 18 to move. At this time, the third spring 14 will also exert a force on the second fixing block 18 until... The first fixing rod 16 is inserted into the corresponding groove 19. Releasing the first fixing rod 16 allows the device to move. When not in use, the roller 2 can be retracted, improving the overall efficiency. When sperm is being transported, the device will shake during movement. The first spring 4 and the first telescopic rod 5 will act as a buffer to prevent the sample box 6 from shaking too much. The third fixing block 20 is subjected to the force of the fourth fixing plate 11. The third fixing block 20 will drive the third fixing rod 21 to move, thereby causing the fixing ring 13 to compress the fourth spring 22, generating a buffering force to prevent the sample box 6 from shaking too much, thus improving the overall practicality.

The side of the telescopic rod 8 furthest from the fourth fixing plate 11 is fixedly connected to the freezing container 1, so that the telescopic rod 8 can be better fixed. The side of the freezing container 1 is fixedly connected to the second spring 7, so that the second spring 7 can be better fixed. The side of the second spring 7 furthest from the freezing container 1 is fixedly connected to the fourth fixing plate 11, so that the second spring 7 can play a buffering role against the fourth fixing plate 11. The second spring 7 is sleeved on the outer wall of the second telescopic rod 8.
