Fine idea! But (Thankfully,) I use a full face mask. But I have used them, Sanitary pads, on wounds that were "leaking" after surgery. Works Great! I also had a time were a blood vessel just would not heal. Blood would actually shoot out of my arm across the room. My Dr just could not understand, because he never saw it or the mess. But you should have seen the nurses at dialysis scramble when it happened there! I just got to were I would grab a pad and put over it and then would go looking for help to wrap coban(that stuff that sticks to itself and not you) around it. This worked super and saved a lot of cleaning and laundry.
