Description

Technical Field

[0001] This invention relates to the field of embryo culture technology, and more specifically, to an embryo culture dish. Background Technology

[0002] In related technologies, a utility model patent with authorization announcement number CN222715371U discloses "a porcine embryo culture dish, comprising: a culture plate, wherein multiple hemispherical culture grooves for placing porcine embryos are evenly distributed on the top surface of the culture plate; a mounting base, one side of which is fixedly connected to one side wall of the culture plate; a metal flexible tube, the lower end of which is fixedly connected to the top of the mounting base, a lamp holder fixed to the upper end of the metal flexible tube, multiple ultraviolet disinfection lamps fixed to the bottom surface of the lamp holder, the multiple ultraviolet disinfection lamps being located above the hemispherical culture grooves, and a control display screen fixed to the other side wall of the culture plate, wherein the ultraviolet disinfection lamps are electrically connected to the control display screen. The experimenter can conveniently adjust the position of the ultraviolet disinfection lamps using the metal flexible tube, avoiding interference with the experimenter's operation due to the ultraviolet disinfection lamps blocking the embryo transfer or placement."

[0003] While the position of the UV sterilization lamp in the above-mentioned scheme can be adjusted, it needs to be removed during operations (such as embryo transfer) and moved back afterward, making the entire process cumbersome. Furthermore, the position and irradiation range of the UV lamp are not precise, potentially creating sterilization blind spots. Additionally, each cover plate has multiple vents, allowing direct exchange with outside air, which can easily contaminate the embryos as air typically contains various pathogens. Therefore, we propose an embryo culture dish. Summary of the Invention

[0004] This invention provides an embryo culture dish that solves the problem in related technologies where the position and irradiation range of the ultraviolet lamp are inaccurate, which may cause sterilization dead zones. In addition, each cover plate has multiple vent holes, which allow direct exchange with the outside air. Since the air usually contains a variety of pathogens, the embryos are easily contaminated.

[0005] This invention provides an embryo culture dish, including a base; a culture seat assembly comprising multiple culture seats arranged in a linear array on the base, with multiple hemispherical culture grooves formed on the top of each culture seat along its length; and a maintenance component disposed on the base, comprising: a first side plate, a second side plate, and multiple cover plate assemblies. The first and second side plates are respectively disposed on both sides of the culture seat assembly, and the multiple cover plate assemblies correspond one-to-one with the multiple culture seats, for selectively sealing the top and both sides along the length of the corresponding culture seat. Each cover plate assembly includes: a sealing plate, with an ultraviolet lamp disposed on the side of the sealing plate facing the corresponding culture seat, and an isolation component disposed between two adjacent sealing plates, the isolation component being used to selectively connect two adjacent culture seats.

[0006] As a further improvement of the present invention, the base includes: a top plate, a bottom plate and annular side plates, and a cavity is defined between the top plate, the bottom plate and the four annular side plates. The top plate has multiple pairs of through holes, and the multiple pairs of through holes correspond one-to-one with multiple sets of isolation components.

[0007] As a further improvement of the present invention, the isolation assembly includes: an isolation plate, two guide rods, a limiting component, and two return components. The two guide rods are slidably connected in the corresponding two through holes, and the bottom sides of the isolation plate are fixedly connected to the tops of the two guide rods. The limiting component is disposed on the top plate and is used to limit the isolation plate when it plays an isolation role. The two return components correspond one-to-one with the two guide rods. The return components are disposed in the cavity and are used to spring up the isolation plate through the guide rods to connect two adjacent culture seats.

[0008] As a further improvement of the present invention, the limiting component includes: an inverted bracket with an opening facing the top plate and a limiting rod. The inverted bracket includes: a crossbeam and two longitudinal beams fixedly connected to both sides of the crossbeam. The bottoms of the two longitudinal beams are fixedly connected to the top plate. A groove is provided on the crossbeam along its length direction. One end of the limiting rod is rotatably connected in the groove, and the other end selectively contacts and engages with the top of the corresponding isolation plate.

[0009] As a further improvement of the present invention, the other end of the limiting rod is made of iron material, and magnet one and magnet two are respectively provided on the top of the isolation plate and in the groove, and magnet one and magnet two selectively attract and cooperate with the other end of the limiting rod.

[0010] As a further improvement of the present invention, the recovery assembly includes: a support plate, a spring, and a mounting base. The support plate is fixedly connected to the corresponding guide rod, the mounting base is fixedly connected to the top of the base plate, the spring is sleeved on the corresponding guide rod, and the two ends of the spring are fixedly connected to the support plate and the mounting base, respectively.

[0011] As a further improvement of the present invention, a sleeve is fixedly connected to the top of the mounting base, and the spring is disposed inside the sleeve.

[0012] As a further improvement of the present invention, the top of the top plate is provided with an installation groove along the length direction of the culture seat assembly, and a fixed shaft is fixedly connected in the installation groove, the axial direction of the fixed shaft being the same as the length direction of the installation groove; the cover plate is a U-shaped structure with an opening facing downwards, which includes: a horizontal plate and two vertical plates fixedly connected to both sides of the horizontal plate, and the ultraviolet lamp is disposed on the horizontal plate; the cover plate assembly further includes: a rotating plate, one side of the rotating plate being fixedly connected to the corresponding cover plate, and the other end of the rotating plate being rotatably connected to the fixed shaft.

[0013] As a further improvement of the present invention, the embryo culture dish further includes: a plurality of air monitoring components, each of which corresponds to a plurality of culture seats. The air monitoring components include: an air inlet pipe, a heating plate, a humidity sensor, a temperature sensor, a CO2 sensor, and an oxygen sensor. The air inlet pipe is disposed on the vertical plate and communicates with the culture seat. The heating plate is disposed along the length of the corresponding culture seat and is located below the culture tank. The humidity sensor, temperature sensor, CO2 sensor, and oxygen sensor are all disposed at the bottom of the horizontal plate.

[0014] As a further improvement of the present invention, the bottom of the culture base is provided with sealing gaskets around the perimeter. The sealing gaskets on both sides are selectively sealed with the corresponding cover plate, the corresponding partition plate, the corresponding side plate one or the side plate two, and the multiple sealing gaskets in the middle are respectively sealed with the corresponding cover plate and the two adjacent partition plates.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention features multiple culture seats on a base, each with multiple culture tanks, and each culture seat corresponds to a sealing assembly. The sealing assembly includes a sealing plate and an isolation component. Multiple ultraviolet lamps are arranged on the side of the sealing plate facing the culture seat, with each ultraviolet lamp corresponding to one of the multiple culture tanks. This makes the setting of the ultraviolet lamps more stable and ensures that the embryos in each culture tank receive ultraviolet light more evenly, resulting in better disinfection. Furthermore, the isolation component can selectively connect two adjacent culture seats, allowing for flexible adjustment of the culture space. This invention is suitable for classification or homogeneous culture, making it more flexible in use.

[0017] 2. By incorporating an air intake pipe, heating plate, humidity sensor, temperature sensor, CO2 sensor, and oxygen sensor, this invention can monitor the growth environment within the independent culture space in real time and make corresponding adjustments, thereby better maintaining the stability of the embryo's survival environment and promoting embryo growth.

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0029] like Figures 1-9 As shown, an embryo culture dish includes a base 1, a culture stand assembly 2, and a maintenance component 3. The base 1 primarily serves for mounting and support. The culture stand assembly 2 is mainly used for culturing embryos. The maintenance component 3 primarily provides a relatively stable and safe condition for embryo culture.

[0030] Specifically, such as Figure 2 and Figure 5 As shown, the base 1 includes a top plate 11, a bottom plate 12, and an annular side plate 13. The top and bottom of the annular side plate 13 are fixedly connected to the top plate 11 and the bottom plate 12, respectively. A cavity 14 is defined between the top plate 11, the bottom plate 12, and the annular side plate 13, and the cavity 14 mainly serves as a mounting surface. The top of the top plate 11 has a mounting groove 112 along the length direction of the culture base assembly 2, that is, along the width direction of the culture base 21. A fixing shaft 113 is fixedly connected in the mounting groove 112, and the axial direction of the fixing shaft 113 is the same as the length direction of the mounting groove 112.

[0031] In addition, such as Figure 5 , Figure 8 and Figure 9 As shown, the culture base assembly 2 includes multiple culture bases 21, which are fixedly arranged in a straight line array on the base 1. Each culture base 21 has multiple hemispherical culture tanks 22 spaced at equal intervals along its length on its top. The arrangement of multiple culture bases 21 facilitates the classification and culture of embryos, making it more flexible and convenient to use. Embryos to be cultured can be placed in the culture tanks 22.

[0032] In addition, such as Figures 1-9 As shown, the maintenance component 3 is mounted on the base 1. The maintenance component 3 includes: a first side plate 31, a second side plate 32, and multiple cover plate assemblies 33. The first side plate 31 and the second side plate 32 are respectively mounted on both sides of the culture base assembly 2, and their length directions are along the length direction of the culture base 21. The multiple cover plate assemblies 33 correspond one-to-one with the multiple culture bases 21, and are used to selectively cover the top and both sides of the corresponding culture base 21 along its length direction.

[0033] The cover plate assembly 33 includes a cover plate 331 and a rotating plate 3314. The cover plate 331 has a U-shaped structure with an opening facing downwards. The cover plate 331 includes a horizontal plate 3311 and two vertical plates 3312 and 3313 fixedly connected to both sides of the horizontal plate 3311. The horizontal plate 3311 is arranged along the length of the culture base 21, and the vertical plates 3312 and 3313 are respectively arranged on both sides of the length of the culture base 21. The ultraviolet lamp 34 can be fixedly connected to the side wall of the horizontal plate 3311 facing the culture base 21, which makes the setting of the ultraviolet lamp 34 more secure and stable, thus facilitating embryo culture.

[0034] Furthermore, multiple ultraviolet lamps 34 can be installed on each horizontal plate 3311, with each ultraviolet lamp 34 corresponding to a multiple culture tank 22. This allows the embryos in each culture tank 22 to receive ultraviolet light more evenly, which is beneficial for the uniform growth of the embryos.

[0035] Furthermore, one side of the rotating plate 3314 is fixedly connected to the corresponding sealing plate 331. Specifically, the rotating plate 3314 can be an L-shaped structure, and one side of the rotating plate 3314 is fixedly connected to the vertical plate 3312, while the other end of the rotating plate 3314 is rotatably connected to the fixed shaft 113. In other words, the sealing plate 331 can rotate around the fixed shaft 113 via the rotating plate 3314, thereby facilitating the adjustment of the position of the sealing plate 331 to seal the top and both sides of the corresponding culture base 21 along its length, thus selectively sealing the culture tank 22 on the corresponding culture base 21.

[0036] In addition, such as Figures 2-5 , Figure 7 and Figure 8As shown, an isolation component 35 is provided between two adjacent cover plates 331. The isolation component 35 is used to selectively connect two adjacent culture seats 21. Multiple pairs of through holes are provided on the top plate 11, and the multiple pairs of through holes correspond one-to-one with multiple sets of isolation components 35.

[0037] In addition, the isolation assembly 35 includes: an isolation plate 351, two guide rods 352, a limiting assembly 353, and two return assemblies 354. The two guide rods 352 are vertically slidably connected in corresponding through holes, and the bottom sides of the isolation plate 351 are fixedly connected to the tops of the two guide rods 352. The limiting assembly 353 is disposed on the top plate 11 and is used to limit the isolation plate 351 when it is functioning as an isolation device. The two return assemblies 354 correspond one-to-one with the two guide rods 352. The return assemblies 354 are disposed within the cavity 14 and are used to spring up the isolation plate 351 via the guide rods 352 to connect two adjacent culture seats 21. The arrangement of the two guide plates and the two return assemblies 354 makes the movement of the isolation plate 351 more stable.

[0038] Specifically, the limiting component 353 includes an inverted bracket 3531 with its opening facing the top plate 11 and a limiting rod 3532. The inverted bracket 3531 includes a crossbeam 35311 and two longitudinal beams 35312 fixedly connected to both sides of the crossbeam 35311, with the bottoms of the two longitudinal beams 35312 fixedly connected to the top plate 11. The length direction of the crossbeam 35311 is along the length direction of the culture seat 21. A groove 35313 is formed on the crossbeam 35311 along its length direction, the bottom of the groove 35313 communicating with the bottom of the crossbeam 35311, one end of the limiting rod 3532 is rotatably connected in the groove 35313, and the other end of the limiting rod 3532 selectively contacts and engages with the top of the corresponding isolation plate 351. It should be noted that the width of the crossbeam 35311 is less than or equal to the gap between the two horizontal plates 3311, and in the vertical direction, the orthographic projection of the limiting rod 3532 is located within the orthographic projection of the groove 35313. This can prevent the limiting rod 3532 from interfering with the rotation of the adjacent cover plate 331.

[0039] Furthermore, the recovery assembly 354 includes: a support plate 3541, a spring 3542, and a mounting base 3543. The support plate 3541 is fixedly connected to the corresponding guide rod 352, the mounting base 3543 is fixedly connected to the top of the base plate 12, the spring 3542 is sleeved on the corresponding guide rod 352, and both ends of the spring 3542 are fixedly connected to the support plate 3541 and the mounting base 3543 respectively.

[0040] In the initial state of use, all the partition plates 351 are in their lowest positions, meaning that the partition plates 351 can seal the gap between two adjacent cover plates 331. At this time, each culture seat 21 has an independent culture space, which facilitates the classification and culture of embryos. Of course, similar embryos can also be cultured, making it more flexible and convenient to use. When the partition plates 351 are in their lowest positions, the bottom of the limiting rod 3532 contacts the top of the corresponding partition plate 351, thereby limiting the upward movement of the partition plate 351. At this time, the spring 3542 is in a compressed state.

[0041] It should be noted that, under the condition that each culture seat 21 has an independent culture space, when the cover plate 331 is in a sealed state over the culture seat 21, the cover plate 331 near the first side plate 31 is sealed with both the first side plate 31 and the adjacent isolation plate 351, the cover plate 331 near the second side plate 32 is sealed with both the second side plate 32 and the adjacent isolation plate 351, and the other cover plates 331 in the middle are sealed with the two adjacent isolation plates 351, thereby enabling each culture seat 21 to have an independent culture space.

[0042] When multiple culture seats 21 need to be connected, for example, when multiple embryos of the same type need to be cultured, the corresponding limiting rod 3532 is rotated upward, thereby releasing the vertical limitation of the isolation plate 351. Under the restoring force of the spring 3542, the isolation plate 351 will move upward until the bottom of the isolation plate 351 is flush with the bottom of the horizontal plate 3311. At this time, the bottom of the isolation plate 351 can seal the gap between two adjacent horizontal plates 3311. The two rising guide rods 352 can seal the gaps between two adjacent vertical plates 3312 and two adjacent vertical plates 3313 respectively. In this way, two adjacent culture seats 21 can be connected through the space between the two guide rods 352, which is convenient and flexible to use.

[0043] As an optional embodiment, such as Figure 4 As shown, the other end of the limiting rod 3532 is made of iron, and magnet 1 3511 and magnet 2 35314 are respectively fixedly connected to the top of the isolation plate 351 and the groove 35313. Magnet 1 3511 and magnet 2 35314 selectively attract and cooperate with the other end of the limiting rod 3532.

[0044] In use, when the isolation plate 351 is in its lowest position, the limiting rod 3532 is vertically positioned, and its other end engages with the magnet 3511 on the top of the isolation plate 351, thus ensuring a more stable contact between the limiting rod 3532 and the isolation plate 351. When it is necessary to release the limiting rod 3532 from the isolation plate 351, the limiting rod 3532 can be rotated upwards until its other end engages with the magnet 35314. This allows the magnet 35314 to limit the limiting rod 3532, facilitating its constraint and reducing interference with the isolation plate 351.

[0045] As an optional embodiment, such as Figure 7 As shown, a sleeve 3544 is fixedly connected to the top of the mounting base 3543. The axial direction of the sleeve 3544 is the same as the extension and retraction direction of the spring 3542, and the spring 3542 is disposed inside the sleeve 3544. The sleeve 3544 can protect and orient the spring 3542, thereby making the spring 3542 more stable.

[0046] In addition, such as Figure 5 and Figure 9 As shown, the embryo culture dish also includes multiple air monitoring components 4, each corresponding to a different culture base 21. Since air contains many pathogens, directly introducing air into the independent culture space can easily contaminate the embryos; therefore, treated clean air is required.

[0047] The air monitoring component 4 includes: an air inlet pipe 41, a heating plate 42, a humidity sensor 43, a temperature sensor 44, a CO2 sensor 45, and an oxygen sensor 46. The air inlet pipe 41 is mounted on the vertical plate 3312 and connects to the culture holder 21, i.e., it connects to the independent culture space of each culture holder 21. During use, clean air can be introduced into the independent culture space through the air inlet pipe 41. The air used for embryo culture typically consists mainly of oxygen, nitrogen, and CO2. The humidity sensor 43 monitors the humidity within the independent culture space, and the humidity can be adjusted by humidifying or dehumidifying the independent culture space through the air inlet pipe 41.

[0048] Temperature sensor 44 is used to monitor the temperature in the independent culture space. Heating plate 42 is arranged in the corresponding culture seat 21 along the length direction of the corresponding culture seat 21 and is located below the culture tank 22. The temperature in the independent culture space can be adjusted by heating plate 42.

[0049] In addition, CO2 sensor 45 and oxygen sensor 46 can monitor the concentrations of CO2 and oxygen respectively, and adjust the concentrations of CO2 and oxygen through the air inlet pipe 41. CO2 sensor 45 can be an infrared absorption sensor, and oxygen sensor 46 can be a paramagnetic sensor, or other suitable sensors. Humidity sensor 43, temperature sensor 44, CO2 sensor 45, and oxygen sensor 46 can all be fixedly connected to the bottom of horizontal plate 3311, that is, to the side wall of horizontal plate 3311 facing the culture tray 21.

[0050] Furthermore, such as Figure 8 As shown, sealing gaskets 47 are fixedly connected around the bottom of the culture base 21, and the sealing gaskets 47 mainly serve a sealing function. The sealing gaskets 47 on both sides selectively seal with the corresponding cover plate 331, the corresponding isolation plate 351, the corresponding side plate one 31, or the side plate two 32, while the multiple sealing gaskets 47 in the middle seal with the corresponding cover plate 331 and the two adjacent isolation plates 351 respectively. Specifically, the sealing gaskets 47 near the side plate one 31 seal with the corresponding side plate one 31, the corresponding isolation plate 351, and the corresponding cover plate 331 respectively; the sealing gaskets 47 near the side plate two 32 seal with the corresponding side plate two 32, the corresponding isolation plate 351, and the corresponding cover plate 331 respectively; and the multiple sealing gaskets 47 in the middle seal with the corresponding cover plate 331 and the two adjacent isolation plates 351 respectively. This allows for better protection of the cultured embryos.

[0051] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
