Description

Technical Field

[0001] The utility model belongs to the technical field of embryo freezing dishes, and in particular relates to a biopsy embryo freezing dish. Background Art

[0002] At present, embryo freezing is one of the important components of assisted reproductive technology. Embryo freezing can reasonably preserve reproductive resources, limit the number of transplanted embryos, reduce the multiple pregnancy rate, increase the cumulative pregnancy rate, reduce patients' medical expenses, and prevent ovarian hyperstimulation syndrome.

[0003] Existing embryo freezing is performed in a standard 60mm culture dish. After squeezing the freezing solution into droplets, the embryos are placed into the droplets. Existing freezing dishes have flat bottoms, but the droplets bulge due to tension. Accidentally shaking the dish can cause the droplets to roll, making it easy for the droplets to collide with other droplets and fuse, potentially mixing up the embryos. Furthermore, biopsied embryos must be strictly numbered. Before freezing, a small number of cells from each embryo must be biopsied and tested. The test results must correspond one-to-one with the embryo's serial number. Embryos with different serial numbers receive different scores and are transplanted in order of their serial numbers. Any confusion during freezing requires a second biopsy of some of the embryo's cells, potentially damaging the embryo. The freezing dish lacks a locking mechanism, which can lead to accidental opening.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the problem that the operator accidentally shakes the freezing dish during the freezing operation, the droplets are easily fused, resulting in the need for a second biopsy of the mixed embryos and the locking mechanism of the freezing dish may be accidentally opened, the basic concept of the technical solution adopted by the utility model is:

[0006] A biopsy embryo freezing dish comprises a freezing dish bottom, wherein the freezing dish bottom is provided with eight embryo storage holes, and the freezing dish bottom is provided with eight cleaning holes, wherein a cleaning hole is correspondingly provided next to each embryo storage hole;

[0007] Two guide grooves are symmetrically provided on the bottom of the freezing dish, a sliding groove is provided below the guide groove, and the guide groove and the sliding groove are connected, a sealing protrusion is provided on the bottom of the freezing dish, a freezing dish cover is nested on the freezing dish bottom, an annular groove is provided inside the freezing dish cover, and two guide blocks are symmetrically provided on the freezing dish cover.

[0008] As a preferred embodiment of the present invention, the cross-section of each embryo storage hole is trapezoidal, each embryo storage hole has a certain slope and depth, and cannot be too steep or too narrow.

[0009] As a preferred embodiment of the present invention, an embryo serial number is printed next to each embryo storage hole, and the embryo serial number is printed on the bottom of the freezing dish.

[0010] As a preferred embodiment of the present invention, a unique freezing dish serial number is printed on the bottom of each freezing dish.

[0011] As a preferred embodiment of the present invention, a sealing ring is installed on the freezing dish cover.

[0012] As a preferred embodiment of the present invention, a mounting groove is provided at the bottom of the freezing dish, and a non-slip rubber pad is installed in the mounting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model has a groove design on the bottom of the embryo freezing dish to prevent the operator from accidentally shaking the freezing dish so that droplets merge with each other, ensuring that the biopsied embryos are not easily shaken out of the liquid and confused with embryos in other droplets during the freezing process. A locking mechanism is provided to prevent the freezing dish from being opened by mistake. The addition of a sealing ring, a sealing protrusion and an annular groove improves the sealing performance of the freezing dish. A non-slip rubber pad is installed on the bottom of the freezing dish to improve the anti-slip performance of the freezing dish, solving the problem that the freezing dish is easy to slip when the operator operates on the operating table. Embryo serial numbers are set for the embryo storage holes to distinguish different embryos, and a unique freezing dish serial number is set for each freezing dish for easy management and query.

[0025] like Figures 1 to 6 As shown, a biopsy embryo freezing dish includes a freezing dish bottom 1, eight embryo storage holes 3 are opened on the freezing dish bottom 1, and eight cleaning holes 4 are opened on the freezing dish bottom 1, and a cleaning hole 4 is correspondingly provided next to each embryo storage hole 3;

[0026] The freezing dish bottom 1 is symmetrically provided with two guide grooves 5, guide groove 5 belows offer sliding groove 6, and guide groove 5 and sliding groove 6 are connected, the freezing dish bottom 1 is provided with sealing protrusion 8, the freezing dish bottom 1 is nestedly installed with freezing dish lid 2, freezing dish lid 2 inside offers annular groove 9, and two guide blocks 7 are symmetrically installed on the freezing dish lid 2. In this arrangement, embryo storage hole 3 is used for isolating different embryos, ensures that biopsy embryo is difficult for swinging out from liquid and is confused with the embryo in other droplets during freezing process, cleaning hole 4 is arranged on embryo storage hole 3 and is convenient for operator to clean embryo, guide groove 5 makes operator need guide block 7 align guide groove 5 just can freezing dish lid 2 be covered on the freezing dish bottom 1, when covering the bottom, freeze dish lid 2 is rotated, guide block 7 slides in sliding groove 6, now, freezing dish bottom 1 and freezing dish lid 2 are locked, this mechanism can prevent freezing dish from being opened by mistake, thereby avoids contaminating embryo.

[0027] like Figures 1 to 6 As shown, in a specific embodiment, each embryo storage hole 3 has a trapezoidal cross-section, and each embryo storage hole 3 has a certain slope and depth, and cannot be too steep or too narrow. In this configuration, the embryo storage holes 3 are provided with a certain slope and depth, and cannot be too steep or too narrow, in order to ensure that even the slightest shaking does not shake out the liquid and embryos, and when the embryos need to be taken out, the operator can also easily suck the embryos out of the embryo storage holes 3.

[0028] like Figures 1 to 6As shown, further, each embryo storage hole 3 is printed with an embryo serial number 11, and the embryo serial number 11 is printed on the bottom of the freezing dish 1. In this setting, because each embryo state is different, the embryo serial number 11 is used to distinguish the embryos to prevent the operator from confusing the embryos.

[0029] like Figures 1 to 6 As shown, each freezing dish bottom 1 is printed with a unique freezing dish serial number 10. In this arrangement, the freezing dish serial numbers 10 can be arranged according to certain rules, such as coding according to the experiment serial number, date, etc., and the freezing dish serial numbers 10 are recorded in a record book or electronic spreadsheet for easy management and query.

[0030] like Figures 1 to 6 Shown, a sealing ring 12 is installed on the freezing dish cover 2. In this arrangement, the sealing ring 12 improves the sealing performance for the freezing dish.

[0031] like Figures 1 to 6 As shown, the bottom of the freezing dish bottom 1 is provided with a mounting groove 13, and a non-slip rubber pad 14 is installed in the mounting groove 13. In this arrangement, the mounting groove 13 is used to install the non-slip rubber pad 14, which improves the anti-slip property of the freezing dish and solves the problem that the freezing dish is easy to slip when the operator operates on the operating table.

[0032] The implementation principle of a biopsy embryo freezing dish of this embodiment is as follows: the operator first places the freezing dish on the operating table, the anti-skid rubber pad 14 can prevent the freezing dish from sliding, and after the freezing liquid is squeezed into the embryo storage hole 3 to make droplets, the embryo is placed in the droplet. The embryo storage hole 3 is provided with a certain slope and depth, and cannot be too steep or too narrow, to ensure that a slight shaking will not shake out the liquid and the embryo, and when the embryo needs to be taken out, the operator can also easily suck the embryo out of the embryo storage hole 3. A cleaning hole 4 is provided next to each embryo storage hole 3 to facilitate the operator to clean the embryo. Different cooling liquids can be placed in the upper and lower rows of embryo storage holes 3 to obtain a variety of Embryos, thereby facilitating the screening of better embryos. After the operation is completed, the guide block 7 on the freezing dish cover 2 is aligned with the guide groove 5 on the freezing dish bottom 1 to cover the freezing dish cover 2 on the freezing dish bottom 1. After covering to the deepest point, the freezing dish cover 2 is rotated to lock the freezing dish bottom 1 and the freezing dish cover 2. When the cover is tight, the sealing protrusion 8 will slide into the annular groove 9, thereby increasing the sealing of the freezing dish. After the operation is completed, the operator can record the freezing dish serial number 10 on the freezing dish bottom 1 in a record book or electronic spreadsheet for easy management and query. At the same time, the results of each embryo biopsy can also be recorded in the record book or electronic spreadsheet through different embryo serial numbers 11.
