Zusammenfassung: | The cannula protector (1) has a tubular sleeve (2) for axially moveable accommodation of a disposable syringe. A bellows (6) is axially compressed by a pre-determined compression length by applying compression force. A radially acting clamp spring (8) is arranged at the sleeve. A length of the sleeve is shorter than a length of a syringe cylinder, the compression length is equal to a length of a cannula, and a sum of the sleeve length and a stretched length of the bellows is equal to a sum of the length of the syringe cylinder and the length of the cannula. An independent claim is also included for a disposable syringe system comprising a cannula protector. |
