Knuckle Infection - Friction Burn (basically)

[Defend]

I have a bit of a small knuckle problem at the moment - improper use of an improvised heavy bag (aka sand filled rice bag) yesterday led to several layers of skin on the knuckle of my right hand disappearing.

Shortly after finishing the workout I noticed a large amount of oozing. I flushed the wound, but no sterile water was available. This morning it was red and sore, about the same as when I went to bed. By late afternoon a yellow film had formed. I cleaned it again, this time with an alcohol wipe. The yellow film reappeared, and then grew into a bubble (see picture). I noticed when I took the picture there was still some foreign material in the wound, so I cleaned it out again. I meant to grab the alcohol wipe but grabbed Benzalkonium Chloride wipe instead - but regardless the foreign material is gone now.

If I was stateside I would just wait it out for a while and see what it does, but since I'm fairly remote and don't have quality medical care at my finger tips, I want to play it a little safer and make sure I'm doing what I should from the start.

Here are the immediate questions, and information that may be relevant to the question:

1) Should I cover the wound? I am in SE Asia, in a jungle environment.

2) How/How Often should I clean the wound? The water I have to work with is rain water. There is some purified drinking water (from what I can tell it is boiled and then put into coke bottles). I have Alcohol, Benzalkonium, and Iodine wipes in my kit. I grew up self-cleaning wounds with rubbing alcohol, so that one is my first instinct but I don't know if it is best.

3) Is there any other way I should be treating it? I did a search... ran across a conversation about leeches and maggots. Too bad i didn't have a finger transplant... I could change the leeches every day after a run. I have to pull 20 of those suckers off anyway. I can get a hold of Cipro, and there's always a chance of obtaining anything else if I know what to request.

Thanks for the help.

note: No formal medical or first aid training. Extent of knowledge is what I've figured out from trial and error self treating, growing up as a country boy. I'm willing to do pretty much anything that needs done myself, but not qualified to advise or treat anybody else.
