Get on FB & Twitter. Have some memes, links to videos, testimonials, links to your site, links to blog posts about your product - basically any content that you can repurpose - and try to automate them (IFTTT, socialjukebox, etc.)

It's not enough to say "This can save lives." For people to connect with it you need to humanize the product. With promotional things you have to message it out as if you're talking with someone - not talking AT them.
