Newly developed 3-liter oxygen concentrator with a built-in respiration detection sensor (pressure sensor) has the respiration synchronizing function allowing maximum oxygen flow of 5-liter during inhalation. While the conventional concentrator keeps oxygen being supplied at the set flow rate, this new type with respiration synchronizing mechanism enables oxygen saving during exhalation and supply of required amount of oxygen during inhalation. This mechanism similar to natural respiration makes the supply system friendly to a patient needing an oxygen concentrator. As a safety means, this new model assures continuous 1.5-liter/min oxygen supply to protect the patient from abrupt lack of oxygen, even when respiration detection fails. This new concentrator model, based on the 3-liter/min type, is ligh (-10kg), consumes about 50% less electricity, and makes less noise (-2 dB or more) than the conventional 5-liter/min type with the large follow rate of up to 5-liter/min. These features will not only save electricity cost, and reduces operating noise, but also does not require having two models of 3 and 5 liter/min prepared to meet the patient's but also does not require having two models of 3 and 5 liter/min prepared to meet the patient's symptom. The lighweight concentrator enables installation in the patient's home by a single person. The new development will surely be of great help to the patient and the nursing people.
