Or general disease is unsuitable for the chronic dacryocystitises patient of operation, puss injection of medicine treatment lacrimal passage infection in lachrymal sac can be removed,
Mitigation symptoms；Normal developing before and after dacryocystorhinostomy, removes the secretions of lachrymal sac accumulation or eliminates postoperative blood coagulation or ooze
Go out thing；Neonatal dacryocystitiss merge the Therapeutic Method of obstructed lacrimal passage.Acute dacryocystitis general nasion portion lachrymal sac area skin occurs
Red, swollen, hot, pain phenomenon, or even homonymy facial swelling, sometimes with before ear and submandibular lymph nodes enlargement and tenderness, eye stream
Tear, can overflow with purulent secretion at lacrimal point hole, can be from skin surface ulceration when abscess is limited to, and usual most of patients has
Chronic dacryocystitises medical history.
The teaching mode of syringing of lacrimal passages of the prior art, student can be by viewing and emulating when learning lacrimal passage exception case
Lacrimal passage structure within model, needs during use to clamp the corresponding site of lacrimal passage with the clip of different model, and simulation lacrimal passage is abnormal
When irrigation of lacrimal passage performance, but can not simulate acute dacryocystitis disease performance, can not be controlled in lacrimal passage using clip simultaneously
The flow of liquid is it is impossible to more accurately simulate lacrimal passage model.
Content of the invention
Of the prior art for solving the problems, such as, the present invention provides a kind of teaching mode of syringing of lacrimal passages, can mould
Intend the disease performance of acute dacryocystitis, and operator can be made to grasp different parts blocking and without degree irrigation of lacrimal passage when narrow
Result.
The purpose of the present invention is achieved through the following technical solutions：
A kind of teaching mode of syringing of lacrimal passages, including in set the head model of cavity, and the one side in head model sets

It is provided with lacrimal point hole at angle, and is provided with the drainage mechanism being connected with lacrimal point hole in the cavity of head model, drainage mechanism includes a left side
Utricule and right utricule, left utricule is connected by left dispatch tube with the lacrimal point hole of left eye model, right utricule and right eye model
Lacrimal point hole is connected by right dispatch tube, left utricule is additionally provided with the left extension tube that can transmit to outside head model, right utricule sets
There is the right extension tube being sent to outside head model, also include the lachrymal sac section model being arranged in facial model, described lachrymal sac area
It is provided with luminous and sounding type device in model, described left dispatch tube, right dispatch tube, left extension tube and right extension tube are respectively provided with
There is screw switch.
Bolt on described screw switch is provided with graduation mark.
The beneficial effects of the utility model：
This utility model can simulate the performance of acute dacryocystitis, helps operator's clear and definite irrigation of lacrimal passage during exercise
Absolute contraindication.Simulate the obstruction of different parts lacrimal passage and the narrow effect without degree using screw switch simultaneously, make
Operator grasps different parts and blocks and the result without degree irrigation of lacrimal passage when narrow.

1. the right prolongation of the left extension tube 7. in the right dispatch tube of the right utricule of the left utricule of left dispatch tube 2. 3. 4. 5. lacrimal point hole 6.
Pipe 8. screw switch 9. luminous and sounding type device
Specific embodiment
It is described in further detail below in conjunction with the accompanying drawings and to this utility model.
As shown in figure 1, a kind of teaching mode of syringing of lacrimal passages, including in set the head model of cavity, and in head mould
The one side of type is provided with the facial model of simulation face, and facial model is provided with two eye model in left and right and nose model, eye
It is provided with lacrimal point hole at the canthus of eyeball model, and be provided with the drainage mechanism being connected with lacrimal point hole, discharge opeing in the cavity of head model
Mechanism includes left utricule 2 and right utricule 3, and left utricule 2 is connected by left dispatch tube 1 with the lacrimal point hole of left eye model, right utricule 3
It is connected by right dispatch tube 4 with the lacrimal point hole of right eye model, left utricule 2 is additionally provided with the left side that can transmit to outside head model and prolongs
Long tube 6, right utricule 3 is provided with the right extension tube 7 being sent to outside head model, as shown in Fig. 2 described left dispatch tube 1, right transmission
It is provided with screw switch, the bolt on screw switch is provided with graduation mark, respectively pin in pipe 4, left extension tube 6 and right extension tube 6
Situation operation to obstruction of lacrimal canaliculus, tear duct obstruction, stenosis of naso lacrimal duct and dacryocystisises, the bolt in rotating screw switch 8, no
With any part pressing from both sides in flat drainage mechanism of degree, simulation different parts block or without degree irrigation of lacrimal passage when narrow
Result.When the screw switch 8 on the left dispatch tube 1 screwing bottom or right dispatch tube 4, from the punching of lower lacrimal point hole 5 inserting needle row lacrimal passage
Wash, flushing liquor will backflow from former lacrimal point, and unobstructed from upper lacrimal point hole 5 inserting needle irrigation of lacrimal passage, illustrate that this model blocks up for lower lacrimal canaliculi
Plug.When the screw switch 8 on the left dispatch tube 1 screwing top or right dispatch tube 4, from upper lacrimal point hole 5 inserting needle row irrigation of lacrimal passage,
Flushing liquor will backflow from former lacrimal point, and unobstructed from lower lacrimal point hole 5 inserting needle irrigation of lacrimal passage, illustrate that this model blocks for superior canaliculus.
When screwing the screw switch 8 in left extension tube 6 or right extension tube 7, from up or down lacrimal point hole 5 inserting needle row irrigation of lacrimal passage, rinse
Liquid all backflows from upper and lower lacrimal point, illustrates that this model is nasolacrimal duct obstruction.Pushed away with syringe in lacrimal ductule within head model
Enter dense sexual secretion, screw left extension tube 6 or the screw switch 8 of right extension tube 7 passage, from up or down lacrimal point hole 5 inserting needle row tear
Road rinses, and flushing liquor all backflows from upper and lower lacrimal point hole 5, has purulent secretion to flow out for chronic dacryocystitises performance simultaneously.When all
All when unscrewing state, flushing liquor flows out the screw switch of passage from nostril, is unobstructed lacrimal passage.When in screw switch 8 wherein
When not exclusively screwing at one, stricture of lacrimal passage state can be simulated.The teaching mode of described syringing of lacrimal passages also includes being arranged on face
Lachrymal sac section model on portion's model, is provided with luminous and sounding type device 9 in described lachrymal sac section model.With syringe along left dispatch tube
1 and right dispatch tube 4 yellow secretions are pushed lachrymal sac body, after opening the switch of luminous and sounding type device 9, pressing lachrymal sac area, religion
Learn model and then send sound：" having tenderness ", and have red led to flash simultaneously, lachrymal sac area takes on a red color, and presses lachrymal sac area simultaneously
Visible yellow color secretions, the above performance for acute dacryocystitis.Acute dacryocystitis are the contraindication of syringing of lacrimal passages, and this practicality is new
Type can help the absolute contraindication of operator's clear and definite irrigation of lacrimal passage during exercise.
