Abstract
A disposable double pointed injection needle has a needle hub to which a thin needle cannula is permanently fastened and which needle hub can be mounted on to a syringe comprising a dose setting and injection mechanism and a cartridge containing a liquid medicine to be injected subcutaneously into a human body. The needle hub is provided with a safety shield guided on the needle hub. The safety shield is urged in a direction away from the needle hub by a spring located between the needle hub and the safety shield. After injection the shield is moved away from the needle hub by the spring and locked in an irreversible position where the safety shield covers the needle cannula and prevents accidental needle stick injuries.
