An MIE apparatus has a blower, a valve system, and a mask hose connector. The blower is connected to the valve system which is connected to the hose connector. During insufflation, the valve system connects exhaust of the blower to the hose connector to cause positive pressure at the hose connector. During exsufflation, the valve system connects the blower intake to the hose connector to cause negative pressure at the hose connector. The apparatus has an automatic mode in which switching between insufflation and exsufflation is based on one or more preset time intervals and a manual mode in which switching between insufflation and exsufflation is based on a manual input from a user.

Insufflation/exsufflation airway clearance apparatus

An MIE apparatus has a blower, a direction valve, an oscillator, and a mask hose connector. The blower is connected to the direction valve, which is connected to the oscillator, which is connected to the hose connector. During insufflation, a direction valve connects exhaust of a blower to an oscillator, causing positive pressure at the hose connector. During exsufflation, the direction valve connects the blower intake to the oscillator, causing negative pressure at the hose connector. The oscillator is a butterfly valve with a 360&#xb0; rotating disc. During insufflation, the disc is fixed to steadily modulate the airflow. During exsufflation, the oscillator is inactive or in flutter mode. When inactive, the disc is fixed to allow maximum air flow. In flutter mode, the disc continuously rotates so that the air flow rapidly alternates between maximum and minimum.
