Without knowing more, I’d advise you to stop spending money on development and try to find a customer. The critical part of this project is not your software but the willingness of small hospitals to pay for your product. Maybe they would sign a letter of intent? Perhaps they would bankroll further development if you sell it as a custom software project. You don’t need a fully functional app before you can sell it. I’ve sold things when all I had was a Figma wireframe.
