| 摘要 |
The invention concerns a syringe comprising a syringe body (12) provided with a needle (22) and a plunger (14) mounted mobile in the body (12). The syringe comprises a mobile guard (36) protecting the injection end (22A) of the needle. The guard (36) is mobile relative to the body (12) between a retracted position inside the body (12) and an active protective position. The guard (36) and the body (12) comprise associated protuberances projecting and recessed for maintaining the guard in retracted position. It comprises a retractable member (70) for positively retaining the engagement of said associated protuberances, when the guard (36) is in a retracted position. The plunger (14) and said retaining member (70) are adapted to retract said retaining member (70) under the action of the plunger being pushed (14) into the body, after injection, thereby releasing the positively retained engagement of the associated protuberances.
