Are there any organizations that donate money to purchase medical equipment for third world countries?

I'm looking to provide mobile clinics to groups that provide medical services in third world countries, especially in Africa. Most of these organizations do not have the resources to purchase these units, so I'm trying to find organizations that are willing to donate the money necessary to help. Foundations do not fund for just medical equipment, but want there to be some type of extensive research project attached to the equipment before they are willing to help.

Are there any organizations that donate money to purchase medical equipment for third world countries?
Email me a cover letter for this project and an Executive Summary (MAX 2 PAGES), with details of the first 120 day period budget and general overall budget spreadsheet and I will see what I can do. I think we can help you.
