How To Verify The Authenticity Of Medical Oxygen Concentrators

Check product certification information: First, check if the oxygen concentrator has a medical device registration certificate. Enter the official website of the National Medical Products Administration and verify the authenticity of the product by entering the "registration certificate number/registrant name/product name" for inquiry.
Check product labeling: Genuine medical oxygen concentrators will not use vague descriptions such as "medical grade" or "health type", but will be clearly labeled as medical device registration certified products. Avoid purchasing products that have not obtained medical device registration certification and only use words such as "household" or "health" to describe them.
Verify oxygen flow rate and oxygen concentration: A true medical oxygen concentrator should meet the relevant regulations of the National Food and Drug Administration, which stipulate that while the oxygen concentration is not less than 90%, the equivalent oxygen output of 3 liters per minute should meet medical standards. Avoid purchasing oxygen concentrators that advertise high traffic but do not meet the oxygen concentration standards for each output flow.
Check portability: If you purchase a portable oxygen concentrator, the actual weight of the portable oxygen concentrator should not exceed 2.4kg, and it needs to have a built-in battery with a usage time of not less than 2 hours. This helps identify oxygen concentrators that claim to be portable but do not actually meet the true portability standards.
Contact manufacturer: There is a 400 phone number for legitimate medical oxygen concentrators. The SN code on the machine (similar to a person's ID card) can be used to contact the manufacturer for verification, ensuring that it is a legitimate product from the manufacturer
