Problems solved by technology

[0002] At present, the anti-hepatitis Yanhuanglian injection small injection made of the traditional Chinese medicine Yanhuanglian as the main component is injected intramuscularly, and the therapeutic effect is relatively slow. In addition, there are the following deficiencies. First, it is inconvenient to use. It is necessary to break the ampoule first, which will inevitably cause the ampoule bottle to fall into pieces more or less; secondly, it needs to be given local high temperature during its production and sealing, which will inevitably affect the stability of the drug; The third is that the main component of the drug, petrizine, is unstable when exposed to light, and the drug in the small injection is highly dispersed to increase the photosensitive surface, which makes the drug easy to deteriorate and unstable; the fourth small injection ampoule is fragile and fragile, and it is inconvenient to carry, transport and store
