How does it work?

How do the glass balls draw the blood out? It appears as though they are suctioned onto his back, so I guess if there's a vacuum in there it would help draw the blood out? How do they create the vacuum?

I wonder ir it's something nasty like they press the globe to his back with a small tube inside, then suck some air out, and then slip the tube out?
