I use them, becuase they are what the diaphragm on my stethoscope is. It doesn't have the hard, traditional diaprhagm. I love using them. Since I'm in nursing school, and only come in contact with 1-2 patients a week, I usually change it about once every 2-3 weeks, depending on the patients I have. The covers are real neat.... they have antimicrobial stuff impregnated in them that is supposed to kill 99.9% of MRSA after 24 hours. After reading the back of one of them, I guess if you use them, you're suppposed to remove the hard diaphragm from your stethoscope before using them too. Their website is www.SafeSEALdiaphragm.com
and I know you can buy smaller quantities on there.... I think they are about $1 each. Could you let me know if you find them cheaper anywhere else???
I just figured out that you can't actually buy them from the safeSeal website, but you can get a sample from there. If you google SafeSeal, a whole bunch of sites come up that you can buy them from.
