In PA you need a prescription to get a syringe used for injections, but I know some hobby stores like Cranberry Hobby carry a syringe that is not used for injections, I think they call it an oiling syringe. In the medical world they are called a needleless syringes for IV uses. They can have a plastic or metal tip(metal would be better) like a syringes, but they are not sharpened. They are probably much safer to use also.
I think Jason is selling some at under the see in cranberry also.
I'm not sure if a medial supply store will sell the needleless syringe or not.
