Abstract

A medical injection device has a syringe. The syringe has a container for the medium to be injected and an injection cannula, which communicates with the container. A needle guard of the injection device can be moved between an injection position and a safe position. In the injection position, the injection cannula can be uncovered in order to inject the medium. In the safe position, a cannula tip of the injection cannula is recessed in a protective component of the needle guard. A securing device securely fixes the protective component in the safe position. The result is an injection device having a needle guard that can be manipulated intuitively and operated safely.
