Description

Technical Field

[0001] This invention belongs to the field of in vitro embryo culture technology, and particularly relates to a dynamic embryo culture device. Background Technology

[0002] Birth defects have long been a significant challenge in the field of reproductive health. These defects primarily include structural malformations such as congenital heart disease and cleft lip and palate, as well as genetic diseases like phenylketonuria and spinal muscular atrophy. Birth defects can occur at any stage of pregnancy, especially in the early stages. With the full implementation of my country's two-child policy in 2016, the prevention and treatment of birth defects has become an important research direction in reproductive biology. However, many mysteries remain regarding the physiological processes of normal human embryonic development. For example, the dynamic changes in X chromosome inactivation, the process of early nervous system development, and the mechanisms of heart formation are all important scientific questions in developmental biology that have not yet been fully explained. Therefore, research on normal human pregnancy and embryonic development not only helps us to further understand the origin of life and embryonic development but also provides a theoretical basis for solving major reproductive health problems such as birth defects.

[0003] Currently, in the field of assisted reproduction, in vitro embryo culture technology is gradually maturing. Common desktop or box-type incubators can only achieve basic culture functions, that is, they can provide basic environments such as temperature, humidity and CO2 mixture, but cannot perform real-time optical monitoring, observe embryo development details, record morphological changes during embryo development, or capture dynamic images that may appear in the later stages of embryo development.

[0004] During the long-term continuous development of an embryo, its nutritional requirements for the culture medium change dynamically, and the embryo itself also slowly releases some metabolic products that need to be removed in a timely manner. However, current incubators require removing the culture dish and changing the medium under external environmental conditions, which inevitably has a potential impact on embryonic development.

[0027] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0028] like Figure 1 and 2As shown in one embodiment of this utility model, the embryo dynamic culture device includes a culture chamber 1, a transfer mechanism 2, a rotation drive mechanism 5, a temporary culture container 6, a separator support 7, and a main culture container 8. The culture chamber 1 contains a culture cavity 101 for storing culture medium. The separator support 7 is connected to the interior of the culture cavity 101 and contains a flow cavity 702 communicating with the culture cavity 101. The main culture container 8 is located inside the flow cavity 702. The temporary culture container 6 is connected to the interior of the culture cavity 101 and contains a temporary cavity for storing temporary liquid. The temporary cavity is separated from the flow cavity 702. The transfer mechanism 2 is mounted on the culture chamber 1 and can be connected to the main culture container 8 to move the main culture container 8 to the temporary cavity. The rotation drive mechanism 5 is connected to the interior of the culture chamber 1 and is driven to the bottom of the separator support.

[0029] The technical solution of this utility model can realize a main culture environment and a temporary environment for changing the culture medium by using two relatively independent temporary cavities and a flow cavity. This avoids the embryo leaving the culture environment and affecting its development, thereby ensuring the safety and orderliness of the culture. It can also improve the convenience and smoothness of changing the culture medium and improve the operational efficiency.

[0030] Specifically, in some implementations, such as Figure 1 and 3 As shown, the incubator 1 includes a main body 11 and a cover 12; the main body 11 and the cover 12 form the culture chamber 101; and the side end of the main body 11 is provided with a circulation port 102 communicating with the culture chamber 101. The main body 11 is made of a transparent material, such as transparent glass.

[0031] Specifically, in some implementations, such as Figure 1 As shown, the main culture container 8 has a placement cavity 801; the placement cavity 801 communicates with the flow cavity 702; and the placement cavity 801 is used to place embryos. The main culture container 8 includes a mesh frame 81 and a cover plate 82 connected to the upper end of the mesh frame 81; the mesh frame 81 is connected to the interior of the flow cavity 702; the cover plate 82 is connected to the transfer mechanism 2. This structure, with the main culture container 8 composed of a split mesh frame 81 and a cover plate 82, can ensure the flow performance between the inside and outside, and can also reduce the damage to the embryos inside from impacts, thereby improving the safety and stability of the culture. In some embodiments, such as... Figure 2As shown, the upper surface of the cover plate 82 is provided with a metal part 83; the rotation drive mechanism 5 is adsorbed and connected to the metal part 83.

[0032] Specifically, in some implementations, such as Figure 1 As shown, the transfer mechanism 2 includes an electromagnet 21 and a transfer drive assembly 22 connected to the electromagnet 21; the transfer drive assembly 22 is connected to the incubator 1; the electromagnet 21 can be attracted and connected to the main culture container 8 (metal part 83). Wherein, as... Figure 3 As shown, the transfer drive assembly 22 includes a rotary cylinder 221, a lifting cylinder 222, and a connecting shaft 223. The rotary cylinder 221 is connected to the incubator 1 (middle cover 12). The mounting end of the lifting cylinder 222 is connected to the rotating end of the rotary cylinder 221. One end of the connecting shaft 223 is connected to the movable end of the lifting cylinder 222. The other end of the connecting shaft 223 is connected to the electromagnet 21. That is, when the culture medium needs to be changed, the rotary cylinder 221 and the lifting cylinder 222 are driven to move the incubator 1 vertically and horizontally into the temporary culture container 6, thereby realizing rapid transfer and medium replacement operations.

[0033] Specifically, in some implementations, such as Figure 1 As shown, the temporary culture container 6 is provided with a first input channel 61 and a first output channel 62; and the first output channel 62 is located below the first input channel 61. When using temporary placement, the input channel 61 is opened and the first output channel 62 is closed to achieve temporary placement of the main culture container.

[0034] Specifically, in some implementations, such as Figure 2 As shown, the inner bottom of the mesh frame 81 is provided with a flow guide groove 803; the flow guide groove 83 is inclined from the placement cavity 801 toward the bottom of the mesh frame 81; the inner bottom of the mesh frame 81 is provided with a flow guide channel 802 communicating with the flow guide groove 803; the flow guide channel 802 penetrates the inner bottom of the mesh frame 81 and communicates with the flow cavity 702. Because the culture medium is fluid, this structure, through the flow guide effect of the flow guide groove 83 and the discharge effect of the flow guide channel 802, can discharge as much waste generated by the embryo as possible, improving internal cleanliness.

[0035] Specifically, in some implementations, such as Figure 2As shown, the inner bottom of the partition support 7 is provided with a discharge channel 701; the two ends of the discharge channel 701 are respectively connected to the flow chamber 702 and the culture chamber 101. The discharge performance of the discharge channel 701 can reduce the excessive residue of waste into the flow chamber 702 and the placement chamber 801, thereby improving the internal cleanliness.

[0036] Specifically, in some implementations, such as Figure 1 As shown, the incubator 1 is equipped with a light-emitting component 3; the light-emitting component 3 is oriented towards the main culture container 8; the incubator 1 is also equipped with a view acquisition component 4; the view acquisition direction of the view acquisition component 4 is oriented towards the main culture container 8.

[0037] Specifically, in some implementations, such as Figure 1 As shown, the rotation drive mechanism 5 includes a rotation drive motor 51 and a support plate 52; the mounting end of the rotation drive motor 51 is connected to the incubator 1; the support plate 52 is connected to the rotating end of the rotation drive motor 51; and the partition bracket 7 is connected to the support plate 52. In other words, the rotation of the rotation drive motor 51 enables multi-angle illumination and view acquisition, improving the comprehensiveness and accuracy of the data.

This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0039] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
