You want to know if an existing patent exists as much to protect you --- as to protect your product. If someone else has a patent and you violate it... that to me in your situation would be at least an equal concern than whether or not you can patent yours. If you can't research patents find someone that can. There are cheap online research services that will do this for you. Again, the ONLY one that can make a definitive decision (other than an OPINION) on this is the USPTO. Even the service you might hire to research this for you... can only give you their opinion based on their research.
In most countries, if two people independently make the same invention, the first one to file a patent application gets the patent. The USA has a "first-to-invent" system, in which the first inventor gets the patent even if he filed an application later.
