Filth & "Large" Amounts

Isa Martin asks:
One of the causes of minor ritual impurity (hadath)in the Hanbali madhab is something exiting from the body, whether the slightest amount of urine or feces from the uretha or anus, or a large amount of filth exiting from somewhere else.

I would assume that this would include a large amount of blood or pus flowing from the body or a person vomitting.  My question is what exactly is considered a "large" amount.  Thank you.

The definition of "large" amount is determined by the person himself. If he considers it to be a lot, then it is. This means that a large amount of blood differs for a butcher and a baker.
