Description

Technical Field

[0001] The invention relates to the technical field of liquid dripping control, in particular to an automatic oil dripping device and a control system. Background Art

[0002] Assisted reproductive technology in vitro fertilization-embryo transfer (IVF) is currently the main means of treating infertility. In the mother's body, the embryo can obtain the appropriate amount of nutrients it needs and is protected by the mother from damage by adverse external factors. However, outside the mother's body, the embryo is completely dependent on the liquid we prepare during in vitro culture. During the reagent preparation process, one person needs to assist the culture dish with his left hand and drip liquid with a dropper in his right hand to prepare the liquid, while another person uses a pipette to quickly cover the previous person's culture dish with oil to complete the reagent preparation.

[0003] The culture dish used in in vitro operation is an extremely important part of the operation. Because the droplets in the prepared culture dish are small, about 20-30ul, if exposed to the air, the water is very easy to volatilize, and the osmotic pressure and pH value will change significantly in a short time. In addition, the droplets exposed to the air are likely to increase the risk of contamination. These factors will have adverse effects on gametes and embryos. Therefore, two people are required to prepare the liquid, one person prepares the droplets, and the other person uses a pipette to absorb paraffin oil to quickly cover the droplets in time, so that as little as possible is in contact with the air, and quickly cover the culture dish with the droplets with oil seals to avoid changes in the liquid composition caused by long-term light and temperature.

[0004] Assisted reproductive technology involves in vitro manipulation of gametes (oocytes, sperm) and embryos, and both gametes and embryos are extremely precious. In vitro manipulation can easily cause damage to gametes, and any minor improper manipulation can lead to assisted pregnancy failure. In the reagent preparation process of assisted reproductive technology, there is not only the problem of labor cost, but also the two people are prone to improper manipulation. Therefore, the present invention proposes an automatic oil dripping device and control system to solve the above problems. Summary of the invention
