[0002] An ampoule is a hard glass container that can be melt-sealed. It is usually in the form of a small glass bottle with a long neck and a narrow mouth. It is widely used in the medical field for carrying or packaging injections. In the prior art, before opening, a scratch is made on the bottleneck with a grinding wheel to disinfect the bottleneck. The ampoule head is turned upward to allow all the liquid medicine to flow into the bottle body. Then, the bottle body and the ampoule head are held with both hands and forced apart to break the bottleneck. There is also an easy-to-break ampoule on the market. The ampoule head is marked with the part pre-cut by the manufacturer, and the ampoule head can be directly broken in this direction.

[0003] However, the traditional operation of opening an ampoule is to scratch the bottleneck of the ampoule with a hard object and then break off the bottle head by hand. In this process, the bottle head will inevitably be broken or the bottle body will be damaged, resulting in drug contamination. Medical staff may be scratched by the fragments, increasing the risk of infection. In order to open the ampoule more safely and protect medical staff, an ampoule opener for clinical use in hematology is designed. Utility Model Content
