Hahah nice shot... Lol. In all seriousness though when was the last time you checked your blood pressure? Sounds like you could be hypertensive with that kind of force exiting a vein.
I said what I said about blood squirting because that usually means arterial blood.
To OP, as mike said though there is certainly nothing to worry about a bit of blood... It happens. As to the amount of gear you lost, it would have been miniscule... If you even lost anything. Certainly nothing to worry about either
