摘要

The utility model provides a medicinal liquid injection mouth, it can improve the yield and the extension life expectancy. Medicinal liquid injection mouth (100) possess casing portion (10), liquid storage part (50), connector portion (36), top frame (60), below frame (70) and diaphragm portion (20). Liquid storage part (50) have opening (56) to by the endocyst in casing portion (10) and stockpile the liquid medicine. Connector portion (36) communicates with the outside of casing portion (10) from liquid storage part (50). The relative casing portion (10) in top frame (60) and below frame (70) has higher rigidity to intercombination and constitute annular framework. Diaphragm portion (20) is formed by the elastomer by in the framework of impressing to cover opening (56).
