So ladies & gents,
can I assume that unless you have a decent level of competency/skill/practice/knowledge that comes with working in the 'hands on' medical profession, then for us luddites its best to stop the bleeding using direct pressure & elevation of the area affected and if that doesnt work, use indirect pressure on the arterial points before the wound..... clean up and cover to prevent further contamination and then hightail it to medical assistance.
Bear in mind, the UK is not that big so a day is the furthest from contact in a worst cas scenario. AND I never travel alone so if 1 goes down others can cover.
