<p>The invention relates to a medical instrument, particularly to an injector with self-destruction structure. The injector comprises a syringe assembly (100), a needle stem assembly (200), and a needle stand assembly (300). The syringe assembly (100) comprises a syringe (110) and a needle cap (120). The syringe consists of a syringe body (111). One end of the needle cap (120) is connected to the bottom of the syringe body (111). A through hole (112) is provided at the bottom of the syringe body (111). The other end of the syringe body (111) is open. The needle stem assembly (200) goes through the open end (114), and can slide within the syringe body (111). The needle stand assembly (200) is provided in the bottom of the syringe body (111). There is a through hole (311) for medicament on the needle stand assembly (300). There is a rest (310) for needle on the needle stand assembly (300). The rest (310) for needle goes through the through hole (112) at the bottom of the syringe body (111). There is a self-destruction structure between the needle stem assembly (200) and the needle stand assembly (300). The needle stem assembly (200) is connected to the needle stand assembly (300) so that the needle stem assembly (200) slides along the inner side of the syringe body (111) with the needle stand assembly (300). The injector according to the invention can be destroyed by itself after being used. Thus the opportunity of spreading diseases is decreased.</p> |
