Nope.

Anything serious means 911 (or hopefully surviving to kick myself for not carrying a SPOT, if I'm out of cell range). Anything minor means it can wait until I get to a convenient store to wash, bandage, or ice it.

As far as lubricating blisters, I do carry a 1/4 oz jar of shea butter that I use as for chamois cream, and it works on blisters too if I should need it. There's a couple of nitrile gloves in my seat pack, that are mostly there for fixing rear tire flats or anything else that means I have to touch the chain - but they could come in handy if I have to touch someone else's blood. I always wear a bra, so if I need a piece of cloth to put pressure on someone's wound, there's always my jersey. I think it would be very unusual for a bici accident to result in life-threatening external bleeding though - I don't think I've ever heard of that happening.
