This invention relates to the interdisciplinary field of assisted reproductive technology and artificial intelligence, specifically to a system and method for constructing an embryonic developmental trajectory map that integrates morphological features. By deeply integrating static morphological features with dynamic morphodynamic parameters, a more comprehensive panoramic map of embryonic development with richer information dimensions is constructed, overcoming the one-sidedness of single-dimensional assessment. Automated analysis of the map using an AI model reduces the influence of subjective human factors, enabling the discovery of subtle developmental patterns and potential differences that are difficult to discern with the human eye, significantly improving the accuracy of selecting high-quality embryos. The provided developmental trajectory map allows embryologists to intuitively examine the entire developmental process of the embryo and the performance of each key node, enhancing the interpretability and credibility of the assessment process. Through more scientific embryo selection, it is expected to improve embryo implantation and clinical pregnancy rates, and reduce multiple pregnancy and miscarriage rates.

The invention provides a fertilization result prediction method and device for in-vitro fertilization and electronic equipment, and relates to the technical field of assisted reproduction. Comprising the following steps: performing oocytoplasm segmentation processing on each frame of collected image, and determining an oocytoplasm image area of each frame of image; dividing the oocytoplasm image region of each frame of image to obtain a plurality of oocytoplasm proton image regions of each frame of image; according to the information of each pixel point in each oocyte proton image region of each frame of image and a preset pixel coordinate offset range, generating average displacement information and average speed information of a particle swarm under each oocyte proton image region of each frame of image, and further generating various motion time sequence feature data corresponding to the target oocyte; and predicting a fertilization result corresponding to the target oocyte according to the multiple motion time sequence characteristic data corresponding to the target oocyte. The method improves the prediction accuracy of the fertilization result, and provides a judgment basis for early fertilization remediation of an embryologist.

The utility model discloses a two-channel manual electric pipette suitable for an embryo laboratory, and relates to the technical field of pipettes. The two-channel manual type electric pipette suitable for the embryo laboratory comprises a pipette body and a pipette cabin used for transferring embryos, the pipette cabin is detachably installed on the pipette body, and the pipette body pumps and exhausts air to the pipette cabin to achieve the liquid suction and drainage functions of the pipette cabin; the pipetting cabin with the two large-capacity cabin bodies is adopted, the storage capacity is large, the pipetting requirement in a laboratory can be met at a time, the two cabin bodies can transfer different liquids and can be independently controlled, frequent pipetting gun heads can be omitted by combining the large capacity, installation is easy, the pipetting cabin and the pipetting gun body can be stably installed only through simple inserting operation, and the pipetting gun is convenient to use and popularize. Moreover, rapid pipetting operation can be realized through electric operation, the two cabin bodies of the pipetting cabin can be selectively mounted, and the two cabin bodies can be mounted together or independently, so that different requirements are met.

The present invention discloses a sheep umbilical cord and placenta development promoting feed, which comprises a TMR daily ration and rumen bypass coated folic acid, and the addition amount of the rumen bypass coated folic acid in each kilogram of feed dry matter is 16 mg. The invention relates to the field of animal nutriology and embryology, aims to improve the survival rate and growth performance of fetuses, and specifically comprises the following steps: adding rumen bypass coated folic acid of a specific dose into daily ration of pregnant sheep, and continuously feeding the pregnant sheep from mating to lambing. According to the method, the fetal umbilical cord diameter can be remarkably increased, the sheep umbilical vein cross section area can be improved, the nutrient substance transportation capability of the umbilical cord can be enhanced, the placenta structure and function can be improved, the placenta trophoblast cell density can be improved, and the maternal-fetal nutrient substance transmission efficiency can be enhanced. The method has the advantages of simplicity and convenience in operation, remarkable economic benefit and the like.
