But often encounter operation failure, can not extract the blood. This article describes a method of subclavian vein puncture to take the body of blood, for peer reference. 1 operation method The body was placed in the supine position, the disposable syringe (50mL) of the piston back out 2cm, about 2cm outside the sternoclavicular clavicle oblique downward 45 ° into the needle puncture, piercing 1cm Into the needle, while pumping the piston. If the process of feeling too much resistance, the syringe can be the air
