Blood Blister

[Sch3mat1c]

I've had this damn thing for nigh on a week now.. last tuesday/wednesday I got pinched in pliers I think, and got a blood blister right in the middle of the useful area of my right middle finger..

So should I've popped it by now? Leave the flap of skin? Cut/peel it off? Leave it be for another week?

P.S. Today I cast a 6x6x2" solid aluminum chassis, 3/16" thick walls! By the nature of sandcasting, I can make more..anyone interested? At the moment I can't make any bigger chassis because I don't have enough sand or large enough flasks to mold it in, but I'm working on that.

i would like to see pictures!

(of the chassis, not the blood blister).

I get blood blisters all the time, and i find the best thing is to pop them with a pin, drain the blood and cover with a band-aid and polysporin for a day or two until the skin looks like it wants to peel. Then peel it of and recover. You should have a useable finger in a week.

Thats just what i do, although a doctor might advise against it.

Any doctors on this forum?

Wait a minute why would a doctor be browsing this forum, they could just buy all thier high end audio gear

i got a bottle of some stuff called new-skin a few years ago, and its still about half full (includes at least one partial spill). its basically a coating that you paint on with the internal applicator brush, wait to dry, and youre good to go with much less annoyance than a band-aid. in a pinch, krazy glue does the same thing but dries harder. its great because you can still do everything without it hurting when stuff touches the raw skin. tear that blister off and paint over, and itll be like nothing happened.

Last time I got a blood blister(from a needle nose pliers, even) I simply took an #2 exacto knife and cut it, then drained it. I find it's far better then having that bump.

Actually, we do have at least one doctor on this forum, Mefinnis. Whether he feels like giving medical advice on these pages or not is another issue.

One thing: if you are going to go popping that blister, at least sterilize the instrument. Boil up a pot of water and boil the knife or whatever for a couple of minutes. Spray alcohol on the instrument and the blister, and alcohol or peroxide afterward.

I am not a doctor, and I don't even know if this is precaution enough. But if you are going to take medical advice from people, like myself, whose sole credentials to dispense it are that we are interested in audio and we haven't dropped dead yet, at least give yourself the edge.

Please sterilize.

The chassis casting sounds very interesting. How are you going to finish it? Will it have a textured surface or are you going to grind or machine it?

Too bad about the blood blister. Makes me think that maybe we should start a scars and mutilation thread. My worst audio related accident came from a rushed jack panel job. I was drilling a whole for a ¼” phone plug when the clamp came loose on the drill press. The steel swung around and caught my finger between it and the upright coulomb on the drill press. Seven stitches and I feel lucky to still be a member of the decimal club.

Then there was the Replacements concert I attended. Think I might have lost 3dB above 12 Khz in my left ear from that one. OUCH! Sound shocked for two days. Would have rather lost an eye.

I am probably going to be sinbinned for this dangerous advice but when I get a blood blister I pop it the second it is poppable. Usually I bite it off or use the same pliers or tool that did it to me in the first place (notice how it was not me who did anything wrong?). It is a superficial wound and as suggested I do use alcohol but never the way suggested above. Usually I take a nice old single malt and sit down in front of the TV and recover. Never had any problems with infections in them so far...

You would probably do equally well just leaving it until it dries up and heads south.

Ok, I'll scan the chassis and pop the blister..
If sterilization is such a worry, fine, I'll use a bit of 22AWG Cu heated to redness, burn through it!

(Since I don't have the tools (mill/shaper) or patience (for sanding or filing) I'll be leaving the chassis as-is.)

It's not a proper job if blood isn't involved somewhere. Be careful though, blood can make nasty stains on aluminium that can be difficult to remove. Methylated spirits works. Oh. You wanted medical advice?
