Gloved hand holding a hypodermic syringe. This syringe has a capacity of 2 millilitres (ml), and is fitted with a needle for shallow injections - into a blood vessel for example. A stream of fluid is seen coming from the needle, as the plunger is pressed in order to remove air bubbles from the syringe barrel and needle. Injection of an air bubble into the bloodstream is potentially dangerous.
