Description

Technical Field

[0001] This utility model relates to the field of dairy farming equipment technology, and in particular to a needleless injection device for dairy cows. Background Technology

[0002] Syringes are common medical instruments. They are mainly used to draw or inject gases or liquids using a needle. Veterinary syringes usually have needles. When administering vaccines or other drugs to animals in large quantities, a single needle is often used for multiple purposes, which can easily lead to cross-infection of animal diseases. Using a single needle for one purpose would also be a huge waste of resources. At the same time, the needle piercing the cow's skin causes irritation, and the resulting stress can reduce milk production. Manual needle insertion is difficult to control well within the skin, and it usually reaches the muscle layer, resulting in the immunized animal not producing a proper immune response. Syringes with needles also pose certain safety risks during injection.

[0003] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the need for frequent needle replacements in existing dairy cow syringes and the fact that injection needles are too stimulating to dairy cows and easily startle them.
