Method to control spraying of high-velocity infected blood droplets during arterial catheterization

Spurting of blood from standard arterial needles during guide-wire insertion can be controlled easily with a syringe and a simple needle inserted along the syringe plunger. With this method, blood droplets that may be infected with the hepatitis or human immunodeficiency virus will not come into contact with the head and neck of the angiographer or interventional radiologist.
