When Daniel has his blood taken, the medic who takes it already has the vial attached to the needle. Medical vials are vacuum sealed, it is this vacuum that draws the blood through the needle, without a vacuum the procedure would not work.

When a medic takes a blood sample they insert the needle first and then insert the vial, this ensures the integrity of the vacuum.
