Description

Technical Field

[0001] The utility model relates to the technical field of avian embryo allantoic fluid, in particular to a device for continuously harvesting avian embryo allantoic fluid. Background Art

[0002] Chicken embryos are chicken embryos. They are an important model for studying animal development and have been widely used in the study of developmental biology. Chicken embryos are placed on egg trays or egg racks with the air chamber facing upward. After disinfection with iodine tincture and alcohol, sterile tweezers are used to knock open the eggshell of the air chamber or remove the transparent tape of the artificial egg window to expose the egg membrane. Be careful not to let the egg shell debris fall into the chicken embryo. Allantoic fluid: After the air chamber is opened, use sterile ophthalmic tweezers to slowly tear off the egg shell membrane, then clamp the chorioallantoic membrane and gently lift it up. Use a Pasteur pipette to pierce the chorioallantoic membrane and directly absorb the allantoic fluid. To prevent the amnion from blocking the pipette mouth, use tweezers to gently press down the amnion and fetal membrane, and then absorb it. Each chicken embryo can generally collect about 8mL of allantoic fluid. In the production of avian embryo virus inactivated vaccines, the industry currently basically adopts a fully automatic harvesting method to harvest chicken embryo allantoic fluid (embryo fluid).

[0003] The existing avian embryo allantoic fluid harvesting device has a single structure, which is not convenient for continuous harvesting of multiple avian embryos. Moreover, when the sucked allantoic fluid is unclean or spoiled, it is easy to contaminate the harvested allantoic fluid, resulting in great waste. Utility Model Content
