GF - don't worry, I'm pretty sure they won't make you insert any IV needles! I think you have to have some kind of license for that, even.
From what you described, I'm pretty sure I had something along these lines after I broke my leg. You could call it a "short term IV" but rather than having it hooked up to saline, the flexible plastic tube stayed in the vein, hooked up to some medical tubing that was taped to my arm. The end piece was a thick plastic thing that had a spot in the middle where you could either screw on a syringe, or push a needle into the tubing. (am I totally butchering this description yet? ).
All they had to do was clean off the plastic thingie, flush the tubing with saline by screwing on the syringe, and then inject the antibiotic via the plastic tube. The only blood was when they first put in the IV, or if they pulled back at all on the saline syringe. Even then it was very diluted and you just saw it in the tube - not too bad.
I don't know what setup they have for him obviously but I'm hoping it's something similar - that was pretty "ick-free".
