Description

a veterinary syringe

technical field

The utility model relates to the technical field of veterinary medical equipment, in particular to a veterinary syringe.

Background technique

Syringe is a common medical tool. As early as the 15th century, Italian Cartinel proposed the principle of syringe, which mainly uses a needle to extract or inject gas or liquid. Syringes can also be used in medical equipment, containers, such as some scientific instruments in chromatography to inject through a rubber septum, injecting gas into a blood vessel will cause an air embolism. The way to remove air from the syringe to avoid embolism is to turn the syringe upside down, tap it lightly, and squeeze out a bit of fluid before injecting into the bloodstream. Each animal inside is injected with anti-epidemic drugs, and it is necessary to repeatedly extract anti-epidemic liquid and then carry out anti-epidemic injection. The method is simple, and the epidemic prevention operation of each animal needs to be operated once, which is repetitive and labor-intensive.
