What are the registration numbers of medical devices?

Look at the first word and the fourth word of the registration certificate first. If it is a country and equipment, it is imported equipment. If the fourth word is equipment and the first word is not country, it is a kind of domestic equipment.

Secondly, if the fourth word is "gold", look at the fifth place after the word "gold". What is the number? What are the types of products? Numbers 6-7 are product classification codes.

If the fourth word is not "gold", look at the first word. If it is "country", it is divided into three categories, and the fifth number is also 3, which can correspond to each other and can be checked. If the first word is not "Guo", then it will be divided into two categories, and the fifth number will also be 2.

This is my profound summary.
