This invention discloses a hospital navigation device and its navigation system, including a mounting ring and an outer ring. The mounting ring extends outward on both its upper and lower sides, forming an upper edge and a lower edge, respectively. Both the upper and lower edges are circular ring structures. The outer ring is located outside the mounting ring, and a mounting cavity is formed between the outer ring and the mounting ring. Multiple sets of covers are arranged around the upper surface of the mounting ring. Each cover is a hollow structure with an outer opening, and an audio guide is installed inside each of the multiple sets of covers. The beneficial effects are: this invention solves the problem of returning the navigation device after use by setting a coin-operated unlocking mechanism at the storage location of the navigation device. The coin is used to unlock the navigation device, and the coin is automatically returned after the navigation device is returned. This avoids the problem of carelessly leaving the navigation device after use, making it highly practical.
