Oxygen Concentrator
We manufacture and sell medical oxygen concentrators that provide concentrated oxygen to patients with chronic respiratory failure who are receiving home oxygen therapy.
Oxygen concentrator for medical use “O2 Fresh-5G”
We provide concentrated oxygen to patients with chronic respiratory failure who are receiving home oxygen therapy.
Our oxygen concentrators are easy to operate with their unique LCD screens and large, easy-to-understand operation buttons. In addition to the industry's top-class energy savings and quiet operation, our oxygen concentrators are also compatible with remote monitoring systems, which support the operation of medical institutions and dealers, as well as allow patients to breathe oxygen comfortably.
What Is “Home Oxygen Therapy (HOT)?”
This therapy involves supplying air containing more oxygen than normal to patients suffering from chronic respiratory disease at their homes from an oxygen concentrator or other device. Oxygen treatment such as this is prescribed by doctors for patients with a lung condition such as respiratory failure or chronic obstructive pulmonary disease (COPD) that prevents them from taking a sufficient amount of air into their bodies.
Principle of Operation of Oxygen Concentrator
How Pressure Swing Adsorption (PSA) WorksAir, the source gas for the concentrated oxygen that is supplied to the patient, is made up of about 20% oxygen and 80% nitrogen. High-concentration oxygen is generated by separating this air into oxygen and nitrogen inside the oxygen concentrator.
Pressure Swing Adsorption (PSA) technology is used to suck in air via an air inlet which is then fed to an adsorption column by a compressor. Adsorption agent in the adsorption column adsorbs nitrogen, so air that passes through the adsorption column contains less nitrogen and more oxygen than normal to become oxygen-concentrated air. The oxygen concentrator is equipped with two adsorption columns. While nitrogen is being adsorbed in one of the columns to turn air into high oxygen content air, the other column discharges adsorbed nitrogen so that the adsorption agent is regenerated. Oxygen concentrated air is supplied continuously to the patient by alternately using the two adsorption columns in this way.
