Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a lacrimal passage teaching model comprises a base plate 1, wherein the base plate 1 is a foam plate, is light and convenient to move, a nasolacrimal duct 2, an upper lacrimal canaliculus 3 and a lower lacrimal canaliculus 4 are connected on the base plate 1, the nasolacrimal duct 2 is connected with the upper lacrimal canaliculus 3 and the lower lacrimal canaliculus 4 through a lacrimal main pipe 5, a lacrimal sac 6 and a lacrimal regulation switch 7 are connected on the lower end of the nasolacrimal duct 2, the top ends of the upper lacrimal duct 3 and the lower lacrimal canaliculus 4 are respectively connected with an upper lacrimal punctum 8 and a lower lacrimal punctum 9, an upper lacrimal canaliculus 3 and a lower lacrimal canaliculus 4 are respectively provided with an upper lacrimal regulation switch 10 and a lower lacrimal regulation switch 11, physiological saline is injected from the lacrimal punctum by using a blunt round needle, and the non-blocking and blocking positions are judged according to the flow direction of flushing liquid. There are generally several situations:
the resistance is not generated during flushing, and the liquid smoothly enters the nasal cavity or the pharyngeal portion of a person, which indicates that the lacrimal passage is smooth;
flushing liquid completely returns from the original injection path to block the lacrimal canaliculus;
injecting flushing fluid from the lower punctum and making the flushing fluid reflux from the upper punctum to block the common lacrimal duct or nasolacrimal duct;
fourthly, the flushing is resistant, part of the flushing returns from the punctum and part of the flushing flows into the nasal cavity, so that the nasolacrimal duct is narrow;
fifthly, the washing liquid flows back from the upper lacrimal punctum and has mucus and sexual secretion which is the obstruction of nasolacrimal duct and the combination of chronic dacryocystitis.
