Ask HN: Apple DevOps question

Hello, I developed an interactive story app for young children about a medical device. I was given a license by the manufacturer to use its image. Apple will not approve it to its App Store, claiming that it is a non-iOS device. The intention of the app is to introduce the medical device to children outside of doctors' offices in a less-scary way.

Does anyone have any suggestions as to how to get an app published to Apple's App Store using a non-Apple manufactured medical device?
