Device of drainage nasal cavity secretion

The utility model discloses a device of drainage nasal cavity secretion, the device including: chamber, nasal cavity connector are stored to negative pressure generator, the one -way gas vent of negative pressure generator, the one -way air inlet of negative pressure generator, negative pressure conduction pipe, secretion, have the switch of a discharge secretion on the secretion storage chamber, and negative pressure conduction pipe and secretion are stored the chamber and is transparently. Connecting patient's the outer nasal cavity in one side through the nasal cavity connector, pressing negative pressure generator, negative pressure generator's gas is discharged through one -way gas vent, and the secretion of nasal cavity enters secretion storage chamber along negative pressure flow direction negative pressure conduction pipe, cocurrent flow. It can be clear away by drainage in time to guarantee nasal cavity secretion. Secretion in patient's nasal cavity flows when storing the chamber along the negative pressure of conduction pipe, and transparent negative pressure conduction pipe and secretion are stored the chamber and is guaranteed the perusal and arrive the property and the volume of nasal cavity secretion.
