Oxylance™ 220 Multi Purpose Oxygen Concentrator, is a clinic type concentrator for Health Units which does not have their own central oxygen system. This device is developed for when it is hard or expensive of supplying oxygen and it is producing oxygen constantly. It does not require fillment or additional raw material. It can be also use for aspiration and nebulization. This device has three main purpose; Concentrating oxygen Turn liquid into aerosol form when used as a nebulizer Suction of secretion Oxylance™ 220 takes its energy from the mains supply and its power consumption is maximum 5 amperes. Device, takes the envorimental air as a oxygen source (with a filter system which eliminates at least 0.5 micron) and passes from molecular sieves. This system seperates nitrogen and other gases from oxygen and it raises the oxygen concentration of ambient air (%21) up to %92 +/-3 which is needed for oxygen therapy. This process continues as the device operates so it does not require refilling. It fulfils the need of long term and constant oxygen therapy. Moreover it does not generate any waste.
