| Zusammenfassung: | A disposable syringe having a double hook element, causing, after a piston stroke toward the end of the socket element of the needle, allowing retraction within the reservoir during the reverse stroke of the piston. A spring between the double hook element and the end of a reservoir lip, when compressed, maintains the double hook element in its position, and when extended, acts to cause the return of the needle within the reservoir. |
