Description

Technical Field

[0001] The utility model relates to the technical field of culture dishes, in particular to a novel embryo culture. Background Art

[0002] Artificial assisted reproductive technology (abbreviated as "assisted reproductive technology") refers to the technology of using medical assistance to make infertile couples pregnant. The most widely used one is in vitro fertilization-embryo transfer technology and its derivative technologies, which is commonly known as test tube babies, that is, the fertilization and embryo cultivation stages will be carried out in glassware, and the embryo and fetal development stages will be carried out in the mother. In order to improve the success rate of pregnancy, multiple embryos are generally implanted into the mother, but this may cause multiple pregnancies, and complications of multiple pregnancies are more common than single pregnancies. Therefore, evaluating the embryos and selecting the embryo with the best developmental potential from multiple embryos for transplantation, and ensuring the success rate while implementing single embryo transplantation is the true meaning of assisted reproduction. A large number of literatures show that embryo collective culture is conducive to the formation of blastocysts. Embryo collective culture refers to culturing multiple embryos together in a single culture drop. The growth factors and other substances secreted by the embryos promote the growth and development of adjacent embryos. The blastocysts obtained by this embryo collective culture method are of better quality and have a higher survival rate.

[0003] The existing new embryo culture dishes have the following problems:

[0004] 1. Different stages of embryo cultivation require different nutrient solutions, and the process of changing the nutrient solution is too cumbersome;

[0021] like Figure 1 , Figure 2As shown, a novel embryo culture dish comprises an outer dish 1, an inner dish 2 is arranged inside the outer dish 1, first blocks 3 are connected to the outer sides of the inner dish 2, a dish cover 4 is arranged above the inner dish 2, and a second block 5 is arranged at the lower end of the dish cover 4. A support plate 6 is arranged at the bottom of the outer dish 1, and the support plate 6 divides the bottom of the outer dish 1 into a first receiving chamber 7 and a second receiving chamber 8. A liquid container 21 is arranged in the first receiving chamber 7, and a first liquid discharge pipe 22 is arranged at the top of the liquid container 21. The first liquid discharge pipe 22 is connected to the hole 11. A second liquid discharge pipe 23 is arranged at the left end of the liquid container 21, and the end of the second liquid discharge pipe 23 passes through the outer dish 1. A valve 25 is arranged on the second liquid discharge pipe 23. The inner dish 2 comprises a cleaning chamber 9 and a culture chamber 10. A hole 11 is arranged at the bottom of the cleaning chamber 9, and a culture unit is arranged in the culture chamber 10. The culture unit comprises a culture tank 12, a trapezoidal tank 13 and a liquid outlet pipe 14. The liquid outlet pipe 14 is connected to the culture chamber 10 and the second receiving chamber 8. The diameter of the liquid outlet pipe 14 is smaller than the diameter of the embryo. The embryo will not enter the second receiving chamber 8 from the liquid outlet pipe 14, but will be fixed in the culture unit. A waste liquid pipe 15 is provided on the side wall of the inner dish 2. A waste liquid tank 16 is connected to the end of the waste liquid pipe 15. A first air bag 17 is provided on one side of the waste liquid tank 16. A liquid storage tank 18 is connected to the top of the dish cover 4. The liquid storage tank 18 is connected to a liquid inlet pipe 19. A second air bag 20 is provided on the top of the liquid inlet pipe 19.

[0024] When in use, the direction of the inner dish 2 is adjusted according to the position of the first liquid discharge pipe 22, and the inner dish 2 is clamped on the outer dish 1 by the first stopper 3, and the culture unit is placed in the inner dish 2 to complete the basic assembly. The embryo is placed in the culture unit to facilitate the observation of the growth and development of a single embryo. The culture unit including the embryo can also be directly taken out according to the actual situation to avoid picking them up one by one. The dish cover 4 is clamped on the top of the inner dish 2 by the second stopper 5 to complete the overall fixation.

[0025] The culture fluid required for culture is injected into the liquid storage tank 18, and the second air bag 20 is squeezed so that the culture fluid in the liquid storage tank 18 is injected into the culture chamber 10 through the liquid inlet pipe 19 under the action of the siphon effect, and the height of the culture fluid in the culture chamber 10 is observed. When it reaches a certain height, the injection of the culture fluid is stopped; when the fluid needs to be replaced, the first air bag 17 is squeezed, and the waste fluid to be discharged enters the waste liquid tank 16 through the waste liquid pipe 15 under the action of the siphon effect.

[0026] By adjusting the opening and closing of the valve on the second liquid discharge pipe 23 , the liquid in the cleaning chamber 9 can be replaced conveniently.

[0027] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here.
