Need a How to Inject Insulin Video

My son was recently diagnosed with Type 1 and I'm looking for a video online that my parents can watch to learn about injecting insulin since they will be babysitting for me next month.  I didn't want to pick some random thing on You Tube and was hoping to find something professional and easy to understand, similar to what we saw in the hospital.  Does anyone know a web site where I can find this?

Thanks very much, I appreciate it.

No problem :)
