You should be more specific -- he gets hurt a lot. But grievously hurt? Well, eppy 19, Sesshomaru shoves his hand through Inuyasha's chest: Go Home to your own time, kagome! The Deadly Trap of Kagura, The Wind Sorceress: Koga hurts inuyasha, and he passes out. In The Wind Scar Fails, Inuyasha gets his wind scar thrust back at him by Kanna and Kagura. The one right after it, Tetsusaiga Breaks, is good, too -- he's already hurt and fights a powerful incarnation of Naraku. There's a spray of Inuyasha's blood in that one. *devilish grin* And he turns into a demon!
Inuyasha's Soul, Devoured, and The Demon's True Nature are pretty good; he gets trapped in a poisonous cocoon, with poison already in his system. And Sesshomaru gets in a few good whacks. Fateful Night in Togenkyo Parts 1 and 2 have a black-haired Inuyasha getting hurt.
The ones in between here I don't know so well. But I don't think they're as juicy as some of the ones I am listing.
In Vanished in a River of Flames, it seems for awhile like he dies... but that's brief and he's not actually hurt. In Divine Malice of the Saint, and Fare Thee Well - Jakotsu's Requiem, he fights Jakotsu as a mortal. That's pretty bloody.
In Destroy Naraku w/ Adamant Barrage, Inuyasha fights Hosenki and gets cut up with adamant. In Possessed by a Parasite: Shippo, Our Worst Enemy, Inuyasha gets a faceful of set beads, and he feels terrible. That one is not very noteworthy, but I included it anyway. In the final episode, a black jewel shard takes him over. He's not actually injured there, but if you're like me, you like the eppies where he turns into a demon.
That oughta do it. Those are the ones in which Inuyasha gets really hurt.
Um... When Sesshomaru was full demon? Or Inuyasha full demon? Well anyway, I'll say both. When Sesshomaru is full demon while fighting Inuyasha it is episode 007. They are there fathers grave fighting over tessaiga. When Inuyasha is full demon fighting Sesshomaru it is episode 52- A demon's True nature.
