Abstract

The invention discloses a bidirectional imaging system for embryos, oocytes and stem cells. The system comprises an objective carrying pallet and an optical device, the objective carrying pallet is provided with multiple recesses for carrying the embryos, oocytes and stem cells, and the optical device shoots the objective carrying pallet, and comprises a first light source, a first optically focusing device, a first object lens, a second light source, a second optically focusing device, a second object lens, a first charge coupling device image sensor and a second charge coupling device imagesensor. Compared with the prior art, the system comprises two light source, optically coupling device and object lens sets, a sample can be shot from two directions simultaneously, the imaging defectof single direction shooting can be overcome, the form of the embryos, oocytes and stem cells can be presented more comprehensively, and evaluation is more accurate.

Description

technical field [0001] The invention relates to a biotechnology medical auxiliary device, in particular to a two-way imaging system for embryos, oocytes and stem cells. Background technique [0002] Over the past 30 years, assisted reproductive technology (ART) has revolutionized the treatment of human infertility and has become widespread. However, ART requires the use of multiple embryos, which leads to a high incidence of multiple pregnancy, which greatly increases the mortality and suffering of infants and mothers, and has a large economic cost. [0003] One of the main reasons for the low success rate of ART is the lack of methods for evaluating embryo quality. The most reliable method currently available for predicting embryo quality is the photographic examination of embryo morphology prior to transfer using a standard transmission light microscopy system. Usually, the embryo is photographed in a certain direction to evaluate the quality of the embryo, but since the...
