Description

Technical Field

[0001] The utility model relates to the technical field of livestock epidemic prevention, in particular to a uterus and ovary multi-position precise drug delivery and artificial insemination device specially designed for cows. Background Art

[0002] Endometritis in dairy cows is a common and frequently occurring disease in dairy farming, mostly concentrated within 2 weeks after delivery, with a general incidence of 20% to 35%. Endometritis in dairy cows is usually a mucous or purulent inflammation of the uterine mucosa. The toxic substances produced by inflammation can kill sperm and embryos and cause infertility in dairy cows. Endometritis in dairy cows has become one of the common causes of infertility in dairy cows, and endometritis in dairy cows usually causes various complications such as ovarian cysts. In my country, endometritis-type infertility in dairy cows accounts for more than 17% of infertility in adult cows. Endometritis in dairy cows can not only affect the estrus and pregnancy of dairy cows, reduce the milk production of dairy cows, and induce diseases such as mastitis, but also cause the loss of reproductive capacity of dairy cows in severe cases. Some acutely ill cows even die of sepsis caused by endometritis in dairy cows. Therefore, endometritis in dairy cows is a serious hazard to the dairy industry and may cause great economic losses. Endometritis in dairy cows has become a disease that is generally valued and urgently needs to be solved in veterinary clinics.

[0003] The existing cow uterus and ovary drug delivery device is easy to fall off when inserted into the cow's vagina during use, which affects the drug delivery efficiency and the treatment effect. Therefore, we have introduced a new cow-specific uterus and ovary multi-site precise drug delivery and artificial insemination device. Utility Model Content
