Abstract

A respirator system is composed of a blower unit for supplying and vacuuming air, a control valve for selecting a positive pressure and a negative pressure from the blower unit to send a vibrating air pressure, a diaphragm for vibrating in connection to the vibrating air pressure to send respiration gas to a patient, and a hollow housing partitioned by the diaphragm into a first pressure chamber cooperating with the vibrating air pressure and a second pressure chamber cooperating with the respiration gas. In addition, the respirator system is further composed of a sensor for sensing the position of the diaphragm in the hollow housing, a pressure regulator for increasing or decreasing the positive pressure and the negative pressure, and a pressure controller for driving and controlling the pressure regulator based on data on the diaphragm position outputted from the sensor. In the respirator system, the pressure regulator increases or decreases the positive pressure and the negative pressure. Thereby, responsiveness can be remarkably improved.
