What kind of media should I choose for the advertisement of medical device products now? Why? What aspects should be highlighted in publicity?

I don't know what kind of medical equipment you do. If it is a large-scale medical equipment, I think it is better to attack the main person in charge according to the individual. If it is a small medical device, products such as oral spray are aimed at the public. If you have money, you can advertise in the newspaper. If you have no money, you can advertise in buildings or buses. If you do brand promotion, you can consider large-scale intensive investment in a region or city, and the short-term effect is ok.
