Spraying quantitative flushing fluid into the simulated nasal cavity from the fluid inlet of the nasal cavity model by adopting a spray head so that the flushing fluid flows out of the fluid outlet from the nasal cavity channel of the simulated nasal cavity, and flushing before testing is completed;
weighing the nasal cavity model washed before the completion of the test to obtain the weight X of the nasal cavity model;
Opening the cover plate of the nasal cavity model, and smearing an adhesive with the weight of S in the frontal sinus cavity, wherein the adhesive is used for simulating human secretion;
The cover plate is covered on the base, and a spray head is adopted to spray quantitative flushing fluid into the simulated nasal cavity from the fluid inlet, so that at least part of the viscous matters flow out of the fluid outlet along with the flushing fluid from the simulated nasal cavity, and test flushing is completed;
Weighing the nasal cavity model after test cleaning, wherein the weight of the nasal cavity model is Y;
the weight Z of the stickies rinsed off was calculated as s+x-Y, resulting in a stickies removal of t=z/s×100%.
9. The nasal cavity simulation flushing method of claim 8, wherein after the flushing fluid is injected into the simulated nasal cavity from the fluid inlet of the nasal cavity model by using a nozzle, the nasal cavity simulation flushing method further comprises:
And observing the flushing process of the flushing liquid in the simulated nasal cavity through the transparent cover plate and/or the transparent base.
10. The nasal cavity simulation washing method of claim 8, wherein at least one of the base and the cover plate is made of a transparent material.
11. The simulated nasal irrigation method of claim 8, wherein an edge of the base forms a first seal and an edge of the cover plate forms a second seal, the first seal and the second seal being capable of cooperating with one another to seal the simulated nasal cavity.
12. The nasal cavity simulation flushing method according to claim 8, wherein the base is provided with a nasal wing made of soft material and positioned at the liquid inlet, and the nasal wing is formed with nostrils communicated with the liquid inlet.
13. The nasal cavity simulation washing method according to claim 8, wherein the nasal cavity model is formed by printing soft and hard materials through a 3D printing technology.
