A safety needle cap (3) for a syringe completely covers the hypodermic needle (4) during non-use or between injections. The needle (4) can be easily exposed with a reduced danger of accidental needle-stick injury. The needle cap (3) can be unlocked from the closed position by being rotated, and then slid backwards onto the syringe barrel (1) by a defined travel distance. Several settings, up to the full extension of the needle, are possible. After use, with the needle retracted into the cap (3), needle stick injuries are once more prevented. |
