These wheels have ratchets inside them so they're locked when facing downslope on one side and roll when facing downslope on the other side. This would cause the seat and rider to spin as they slid down. The faster they slide, the faster they spin.

The centrifugal force should project most of any resulting vomit over the sides of the slide to keep the water relatively clean.

You could also make versions for snow and if you're really insane, just put on larger wheels and ride it down a hill. Body bag not included.

After the accident we kept asking him if he knew his blood type for when the ambulance arrived. He just kept saying "Be positive", but it was hard under the circumstances.

He was obviously more optimistic than the last accident victim I helped. I told him he was going to die unless we knew his blood group, and he just said "Oh."

Maybe he just knew it was his time. Gotta be respectful of that.

If it didn't cost much it would be centrifrugal.
