Protection from Needle-Stick InjuriesThe Monoject hypodermic safety needle is a hinged safety device designed to protect healthcare workers from exposure to needle-stick injuries. The integrated safety shield can be activated using your thumb by gently push down on the shield, or activated using a flat surface by gently pressing the safety shield against the surface. An audible and tactile click verifies the safety device has been activated. Your thumb remains above the needle at all times, preventing possible needle sticks. The Monoject safety needle and syringe combination also available.
