Have you considered COMPEX? It works very well. I have information online and stock it at my clinic. It might be exactly what you have been hoping for.
Please visit my old site: http://www.xpeditionsmagazine.com/wills/index-B.html
and scroll down to COMPEX. There are 2 links there. One is of my experiences and the other has pictures from the experiences of others.
I hope this helps you.
God Bless
