Technical Field

[0001] This utility model belongs to the technical field of culture dishes for embryo transfer and in vitro fertilization, and relates to culture dishes for embryo transfer and in vitro fertilization. Background Art

[0002] Chinese patent CN208440644U discloses an in vitro fertilization (IVF) culture dish, comprising a dish body with a functional section. The functional section includes a functional groove containing a sperm loading groove, multiple oocyte storage grooves, and multiple fertilized egg culture grooves. The sperm loading groove is connected to the oocyte storage grooves via multiple flow channels. Each fertilized egg culture groove corresponds to one of the oocyte storage grooves. The height of the walls of the sperm loading groove, oocyte storage grooves, and fertilized egg culture grooves is lower than the height of the walls of the functional groove. This IVF culture dish, by providing flow channels between the sperm loading groove and the oocyte storage grooves, can simulate the natural fertilization process to select the best sperm before fertilization. However, existing technologies make it inconvenient to separate embryos after IVF, and the culture dish is inconvenient to fix during use. Therefore, there is an urgent need for culture dishes suitable for embryo transfer and IVF. Utility Model Content

[0023] By adjusting the height of the first lifting plate 2 and the second lifting plate 3, the placement cylinder 6 is adjusted to a suitable height. During the adjustment of the height of the placement cylinder 6, the culture dish 8 is fixed in the placement cylinder 6 by the clamping component, which facilitates the observation of the fertilization of the fertilized eggs in the culture dish. The height of the first arc-shaped groove 10 is higher than the height of the second arc-shaped groove 11, which facilitates the movement of the fertilized eggs to the position of the second arc-shaped groove 11. The sliding connection between the S-shaped blocking plate 12 and the S-shaped guide plate 9 facilitates the movement of the fertilized eggs in the first arc-shaped groove 10 to the second arc-shaped groove 11.

[0024] The guard plate 1 is rotatably connected to a power rod. A handle 4 is fixedly connected to one end of the power rod extending out of the guard plate 1.

A first connecting rod 19 is fixedly connected to the left side of the receiving rod 18, and a second connecting rod 20 is provided to the right side of the first connecting rod 19. All the rotatable connections mentioned above are achieved through bearings. The second connecting rod 20 is rotatably connected to the receiving rod 18. The first lifting plate... 2 and the second lifting plate 3 both have placement slots 21 on the inner left side. The first connecting rod 19 and the second connecting rod 20 are hinged to the upper side of the first cross scissor connecting rod 24. The first cross scissor connecting rod 24 is hinged to the upper side of the second cross scissor connecting rod 23. The upper two sides of the second cross scissor connecting rod 23 are fixedly connected to the second sliding rods. The two second sliding rods are slidably connected to the upper placement slot 21.

[0025] By rotating the handle 4, the handle 4 drives the power rod to rotate, the power rod drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, and the worm wheel drives the receiving rod 18 to rotate. Due to the fixed connection between the receiving rod 18 and the first connecting rod 19, and the rotational connection between the second connecting rod 20 and the receiving rod 18, the first lifting plate 2 and the second lifting plate 3 are adjusted to a suitable height position through the transmission of the first cross scissor connecting rod and the second cross scissor connecting rod.

[0026] The clamping component includes two locking rods 14 that are slidably connected to the front and rear sides of the placement cylinder 6. The placement cylinder 6 has through holes through which the locking rods 14 pass. The locking rods 14 pass through the through holes and extend into the placement cylinder 6 to achieve a slidable connection between the locking rods 14 and the placement cylinder 6. An arc-shaped clamping piece 15 is fixedly connected to the inner side of each locking rod 14. A tension spring is fitted onto each locking rod 14.

[0029] Figure 1 In this device, the sliding plate 7 is located in the middle of the top plate 16. At this time, the tension spring is subjected to an external force. When the first lifting plate 2 and the second lifting plate 3 move upward, the second lifting plate 3 drives the placement cylinder 6 to move upward. During the upward movement of the placement cylinder 6, the sliding plate 7 moves away from the top plate 16. At this time, under the force of the tension spring, the two locking rods of the sliding plate 7 move inward at the same time, thereby driving the two arc-shaped clamping plates 15 to move towards the culture dish 6 at the same time, so as to clamp the culture dish 8 in the placement cylinder 6.

[0030] The base 5 has multiple evenly distributed countersunk holes.

[0031] The locking screw can be passed through the countersunk hole to secure the device to the worktable.
