Medical‑grade concentrators are regulated by the National Medical Products Administration (NMPA), which certifies and issues a medical device registration certificate. They are primarily intended for patients with respiratory conditions su...
Our portable oxygen concentrators do not require 3C certification when carried on airplanes or high‑speed trains. Currently, 3C certification only applies to power banks, not to the dedicated lithium batteries used in our concentrators. As...
For a desktop (stationary) concentrator, 5L means a flow rate of 5 liters per minute. Take our 5L portable concentrator as an example: it actually delivers 1.0 L/min. Under the concept of equivalence, this is multiplied by 5 (1.0 × 5 = 5),...
Blood oxygen is one of the key indicators of human health. Blood oxygen saturation (SpO₂) refers to the concentration of oxygen in the blood and is a critical physiological parameter of the body's respiratory and circulatory system. By...
The core principle of portable oxygen concentrators is based on molecular sieve adsorption technology (PSA), which physically separates nitrogen and oxygen from ambient air to achieve a continuous output of high‑concentration oxygen. Ambie...
