Embryo culture device and carrier thereof

Abstract

The invention relates to an embryo culture device, which comprises a culture tank, wherein the culture tank is provided with a cover; the culture tank and the cover are in threaded matching; air vents are formed in a covering screw thread of the culture tank; a carrier holding platform is arranged in the culture tank; the carrier holding platform is higher than the air vents; a carrier is arranged on the carrier holding platform; the bracket is of a hollowed porous structure which comprises a porous plate; and a convex ring is arranged on the porous plate. With the application of the device disclosed by the invention, the number of carbon dioxide incubators required by a test-tube baby laboratory can be remarkably reduced, so that the space of the laboratory can be greatly diminished and the consumption amounts of carbon dioxide and nitrogen can be greatly reduced; and the safety, stability and embryo quality of human embryo culture in vitro as well as the safety of the laboratory can be improved.

Description

technical field [0001] The invention relates to an embryo culture device and its bracket, belonging to the technical field of in vitro fertilization-embryo transplantation. Background technique [0002] Human in vitro fertilization-embryo transfer technology (InVitro-Fertilization and EmbryoTransfer, IVF-ET) has been developed for more than 30 years and has made great progress. The current in vitro fertilization and embryo culture are all completed in a carbon dioxide incubator, relying on the interaction and communication between the constant temperature and constant concentration of carbon dioxide in the incubator and the chemical components in the medium to maintain the sperm and egg fertilization and embryo growth. physiological environment. However, there are some defects or deficiencies in the existing culture system, whether in the hardware equipment (cultivation device or incubator) or in the culture medium. As far as the hardware is concerned, the existing culture...

Problems solved by technology

As far as the hardware is concerned, the existing culture device (incubator) is an open system. The gas in the carbon dioxide incubator needs to communicate with the air outside the box, that is, the embryo laboratory, to maintain the gas in the incubator or the device. Therefore, such an open system has the following obvious deficiencies or defects: First, the gas concentration and temperature in the device are actually in a dynamic equilibrium state, and the gas concentration and temperature fluctuate within a certain range. The size of the fluctuation depends on the type and quality of the device or incubator and the frequency of opening the door of the incubator; second, volatile organic compounds and harmful physical and chemical factors such as ozone in the laboratory can enter into the laboratory through this open gas exchange system. In the carbon dioxide incubator, it will cause damage to the embryo, or even death; the third is that when the door of the carbon dioxide incubator is opened, the gas in the incubator will overflow a large amount, which will inevitably cause the gas concentration and temperature in the incubator to fluctuate violently. The degree of embryo damage caused by such violent fluctuations also increases

However, this kind of equipment is relatively expensive, and it is difficult for hospitals with poor conditions to afford the equipment purchase cost. At present, the age of marriage is gradually increasing, and the success rate of natural pregnancy for older couples is relatively low. Mother's dream, in vitro fertilization-embryo transfer technology must be promoted
