Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drug injection, in particular to a drug injection device. Background Art
[0002] Syringes are a common medical device. As early as the 15th century, Italian Catinel proposed the principle of syringes. It mainly uses a needle to extract or inject gas or liquid. Syringes can also be used for medical equipment, containers, and some scientific instruments in chromatography to inject through rubber diaphragms. The emergence of syringes is an epoch-making revolution in the field of medical devices. The process of extracting and injecting gas or liquid with a needle is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod. It is used to inject a small amount of liquid or liquid into or extract it from areas that are inaccessible by other methods. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in.
[0003] When people need to perform long-term and multiple injection operations, such as vaccinating livestock, they either need to buy specially developed livestock vaccine syringes to operate, but their prices are relatively high and they are more suitable for use in large-scale livestock breeding. Therefore, there is an urgent need for a low-cost and labor-saving drug injection device. Utility Model Content
