Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blastocyst size measurement, in particular to a blastocyst classification dish. Background Art
[0002] The embryo begins to divide from a single-cell fertilized egg into two-cell, multi-cell, primary blastocyst, expanding mid-blastocyst, and expanded complete blastocyst stages. Among them, the size of the embryo remains almost unchanged from the single-cell fertilized egg to the primary blastocyst, and the size of the embryo gradually increases in the subsequent stages. When transplanting embryos of animals such as cattle and sheep, the embryo needs to develop to the blastocyst stage. The size of the embryo is the key to embryo quality assessment and embryo transplantation, and it is very important to accurately measure the size of the embryo. In the prior art, when classifying blastocysts, there is a lack of convenient tools for measuring the size of blastocysts in the laboratory. Summary of the invention
[0003] The utility model aims to provide a blastocyst classification dish to solve the problems raised in the above-mentioned background technology and quickly determine the diameter size range of the blastocyst.
[0004] A blastocyst classification dish comprises a classification dish body, a blastocyst storage pool, and a plurality of measuring pools; the blastocyst storage pool and the plurality of measuring pools are arranged on the bottom of the classification dish body, and the diameters of the plurality of measuring pools are gradually increased in sequence.
[0005] Furthermore, the plurality of measuring cells are hemispherical.
[0006] Furthermore, among the multiple measuring cells, the diameter of the smallest measuring cell is 130-150 microns.
[0007] Furthermore, the diameters of the multiple measuring cells are an arithmetic progression, and the diameter of each row increases gradually from left to right, and the diameter of each row also increases gradually from top to bottom.
[0008] Furthermore, the diameters of the multiple measuring cells are 130 microns, 150 microns, 170 microns, 190 microns, 210 microns, 230 microns, 250 microns, 270 microns, 290 microns, 310 microns, 330 microns, 350 microns, 370 microns, 390 microns, 410 microns, 430 microns, 450 microns, 470 microns, and 490 microns, and the sizes are marked near the corresponding measuring cells, preferably uniformly marked above the corresponding measuring cells.
[0009] Furthermore, the classification dish body is square or round.
[0010] Furthermore, the classification dish body, the blastocyst storage pool and the measuring pool are integrally formed.
[0011] Furthermore, the blastocyst storage pool is a cylinder arranged above the bottom of the classification dish body, and the height of the cylinder is lower than the height of the classification dish body.
[0012] Furthermore, the blastocyst storage pool is a groove arranged at the bottom of the classification dish body.
[0013] Furthermore, the blastocyst storage pool is detachable from the classification dish body, and the blastocyst storage pool is fixed to the bottom of the classification dish body by a suction cup or a buckle.
[0014] The blastocyst measurement method of the utility model is as follows: the blastocysts to be classified are concentrated in a blastocyst storage pool, and the blastocysts to be classified are placed one by one from the blastocyst storage pool into a measuring pool close to the size of the blastocyst under a microscope. If the blastocyst is exactly half in the measuring pool and half out of the measuring pool, the diameter of the measuring pool is the diameter of the blastocyst; if the blastocyst is less than half in the measuring pool and more than half out of the measuring pool, that is, the part of the blastocyst out of the measuring pool is more than one half, the blastocyst is moved to the next measuring pool for measurement until the blastocyst is exactly half in the measuring pool. If half of the blastocyst is exposed in the measuring pool, or the part of the blastocyst exposed in the measuring pool is close to the part in the measuring pool, then the diameter of this measuring pool is the diameter of the blastocyst; if more than half of the blastocyst is in the measuring pool and less than half is exposed in the measuring pool, that is, the part of the blastocyst exposed in the measuring pool is less than half, then the blastocyst is moved to the previous measuring pool for measurement until the blastocyst is exactly half in the measuring pool and half exposed in the measuring pool, or the part of the blastocyst exposed in the measuring pool is close to the part in the measuring pool, then the diameter of this measuring pool is the diameter of the blastocyst. The operator classifies the blastocyst according to the measurement results of the blastocyst diameter. This measurement method can be used to classify the blastocyst according to the diameter size, providing a scientific basis for embryo transplantation.
[0015] By adopting the above technical scheme, convenient measurement of blastocysts is achieved, and classification is convenient according to the measurement results. Suitable blastocysts are selected for transplantation according to the needs of embryo transplantation, thereby improving work efficiency and the success rate of transplantation. Compared with the prior art, the beneficial effect of the utility model is that by using the blastocyst classification dish of the present application, the operator can simply compare the blastocyst with the diameter of the measuring pool to determine the diameter of the blastocyst, which is easy to operate and improves the efficiency of blastocyst classification.
