摘要：
A disposable secure insulin injection needle, comprising a needle body (6), a needle seat (2), a main housing (3), an outer sheath (8) and a trigger tube (5). The needle seat (2) is formed by fixedly connecting a seat disc (23) and a seat rod (24). An outer edge of the seat disc (23) and an inner edge of the main housing (3) have a slide positioning connection relationship. That is, during mounting of the injection needle, the seat disc (23) moves from a first locating position to a second locating position using an axial thrust at the head of an insulin pen, the rear part of the trigger tube (5) is sheathed on the seat rod (24), and the front end abuts against an inner end face of the front part of the outer sheath (8) a third locating structure is disposed between the trigger tube (5) and the seat rod (24) when the trigger tube (5) is located at a third locating position with respect to the seat rod (24), the seat disc (23) is located at the first locating position with respect to the main housing (3) and when the seat disc (23) moves from the first locating position to the second locating position in the main housing (3), third locating between the trigger tube (5) and the seat rod (24) is removed so as to form slide connection. The injection needle associates a state whether the trigger tube (5) is unlocked after being located with a state whether the insulin pen and the injection needle get ready for injection, thereby improving the use security and convenience.Cette aiguille hypodermique à insuline jetable sécurisée comprend un corps daiguille (6), une embase daiguille (2), un corps principal (3), un manchon de protection externe (8) et un dispositif de poussée (5).
