Hello, I would like to ask you a song question, is the oxygen concentrator for home use a medical device? My mom bought an oxygen concentrator for a class with the elderly.

Oxygen concentrators are classified as Class 2 medical devices. If the oxygen concentrator you bought does not have a medical device approval number, it is an unauthorized product.

Regular home oxygen concentrator in the scope of application of the product will be marked, such as the following oxygen concentrator:

Registration No. 粤械注准20152540058
