ABSTRACT:
A mucus suction device includes a pump housing, collection vessel connected to the pump housing, and a fluid conduit connected to the vessel and adapted for placement in a nostril. The pump housing, vessel, and conduit together define an air path. The pump housing encloses a flexible diaphragm and a motor to pulsate it. Behind the diaphragm is an air chamber communicating with the fluid conduit and with a discharge passage to atmosphere. The collection vessel includes a first nipple for connection with the conduit and a second nipple for connection with the air chamber. The fluid conduit includes a mucus tube for placement into a nostril. The air path also includes check valve, one between the tube and the air chamber, and the other between the air chamber and the discharge passage. Pulsation of the diaphragm moves air through the discharge passage and generates vacuum pressure in the fluid conduit to draw mucus into the fluid conduit.
