摘要：
An insulin injection needle with a needle tip protection function, comprising a needle body (6), a needle seat (2), a main housing (3) and an outer sheath (8). The insulin injection needle is characterized in that: a trigger tube (5), a front sleeve (4) and a spring (7) are disposed in the main housing (3)； the trigger tube (5) is configured to protect an injection section of the needle body (6) before the needle is used； and the front sleeve (4) is configured to protect the injection section of the needle body (6) after the needle is used. Before the needle is used, the trigger tube (5) extends from the main housing (3) and is in a needle body protection state, and the front sleeve (4) is located in the main housing (3). After the needle is used, the trigger tube (5) is located in the main housing (3), and the front sleeve (4) extends from the main housing (3) and is in a needle body protection state. Unlocking of the trigger tube (5) and the front sleeve (4) is associated with a state whether the injection needle gets ready for injection. During mounting, unlocking of the trigger tube (5) and the front sleeve (4) is triggered using a tail cover (1) and the needle seat (2), thereby improving the use security and convenience.Cette aiguille hypodermique à insuline dotée d'un manchon de protection de pointe d'aiguille comprend un corps d'aiguille (6), une embase d'aiguille (2), un corps principal (3), un manchon de protection externe (8) et se caractérise en ce que le corps principal (3) renferme un dispositif de poussée (5) destiné à protéger le segment d'injection du corps d'aiguille (6) avant utilisation, un manchon avant (4) destiné à protéger le corps d'aiguille (6) après utilisation et un ressort (7). Avant utilisation, le déclencheur (5) s'étend depuis le corps principal (3) jusqu'à l'état de protection du corps d'aiguille, alors que le manchon avant (4) se trouve dans le corps d'aiguille (3). Après utilisation, le dispositif de poussée (5) vient dans le corps
