A needle holder or adapter can be used as a combination system with both a syringe and a vacuum tube. This allows for easy transfer of blood samples between the syringe and the vacuum tube during blood collection procedures.

The syringe needle was invented in the United States by Charles Pravaz and Alexander Wood in the mid-19th century. They developed the concept of a hollow needle attached to a syringe for medical injections.
The needle of the syringe is put into a container that has medicine in it. The handle of the syringe is pulled back, drawing the medicine into the tube. The needle is then jabbed into the body and the handle is pushed forward, sending the medicine from the tube, through the needle, into the body.

Hypodermic needle.
No, a tuberculin syringe is intended for use in intradermal injections and the flu shot is given intramuscularly. The needle on a tuberculin syringe is not the right size.
The pressure generated by a syringe is a result of how hard the plunger is pushed and the internal diameter of the needle, not the size of the syringe.
It depends what substance is going into the syringe. If it is a medication, sometimes the doctor will attach a hollow needle to the syringe and place the needle into a bottle of medication - this way he can draw up the medication into the syringe via the needle. The needle will then be removed from the syringe and discarded. The alternative method is that some bottles have a silicone stopper around the top, with a tiny hole in the middle where the (needle-less) syringe fits. You stick the tip of the syringe into hole so that it fits snugly, turn the bottle upside down and draw up the medication. The snug fit means that the medication doesn't drip everywhere when you turn the bottle upside down.
To expel an air bubble from a syringe, first hold the syringe with the needle pointing up. Then gently tap the side of the syringe to move the air bubble towards the needle. Finally, push the plunger slowly to expel the air bubble out of the syringe.
