Your circulatory system is under pressure due to the heart. You'll be pumping out blood and bleeding out before you start taking in air. 

Imagine a hose spraying water. Does air get into the hose? 

So yes, sometimes it does get in, especially with veins returning low pressure blood to the heart, but it's not going to happen with your average cut or wound.
