Abstract: A portable, self-cleaning or flushing evacuator apparatus aspirates and removes sinus fluids from nasal and sinus cavities. The apparatus includes a housing having a vacuum producing compartment, a mucus collecting compartment, a sterilizing compartment and a storage compartment. A suction pervious barrier separates the mucus collecting compartment from the vacuum producing compartment. A rotatable propeller is mounted to a drive motor and located in the vacuum producing compartment. The propeller is effective to produce only a suction to draw through a catheter which is inserted into a nasal opening at one end and connected to the mucus collecting compartment at the other end thereof. The vacuum producing propeller is effective to produce an amount of suction sufficient to withdraw mucus material from the sinus cavities without causing irritation of the soft nasal tissues.
