In today's society, there is a huge base of visually impaired patients, but there is no rational drug use system for them. The accuracy, safety, and compliance of medication for visually impaired patients are very low.This product is an audible instruction ring set, which consists of a ring that can scan a QR code, a wireless headset that broadcasts medicine instructions, and a matching charging box. By touching the special Braille printed with uv concave and convex, find the position of the QR code and scan it, and finally the earphone plays the medicine instructions. This will help the visually impaired in the use of drugs.
