Patrick was out bowling last night and hurt himself, so we went and got some bandaids. But just like everything else in life, as it goes on it gets more complicated. Bandaids come in different sizes and shapes, but also different purposes - more complicated. Let's take a closer look.
As you can see there's a wide array of different types of bandages - even more than what Patrick has on head here. But they can be broken down into different types of categories. There's a standard bandage like this that Patrick has on with differnet sizes and shapes depending on your needs. Also there's what's called occlusive or semi-occlusive bandages which are very useful in certain situations. They can be left on for two or three days, they generally keep the air out, which is good for certain types of wound healing, and they keep the wound moist. Those are occlusive or semi-occlusive.
There are also different types of bandages that have antibiotic oinment on them and it's recommended that you don't use those types of bandages. Better yet, put the Bacitracin or antibiotic ointment on first, then the bandage. There's also bandages like this to stop bleeding - again, not such a good idea. And lastly bandages like this that supposedly stop scarring - they generally don't work - but if you want to try it, let the wound heal first then put the anti-scarring bandage on last.
The bottom line with bandages is: tailor it to the wound, but more importantly, wound care. If you have a puncture wound or a dirty wound, take care of that wound because it could get infected. Also if it's a bite, an animal bite or human bite, it could be real trouble. The human bite is much worse than the animal bite, by the way. And lastly, if you're diabetic, get to your doctor because it could be a serious problem.
