Hi Chris,
You`ll need to be more specific. "Health care product" can mean anything from healthy food, to exercise equipment to vitamin supplements to electrical muscle stimulators. Who can help you design it will depend a lot on what `it` is. Many of these types of products are regulated by the US government (FDA, FCC, USDA, etc.) and who would know how to deal with these design constraints depends a lot on the product.
Success to You!
