Embodiment one
A kind of constant pressure contained eustachian tube as shown in Figures 1 to 5, including：Contained eustachian tube 1, constant-voltage equipment 2；Permanent
Pressure device 2 includes：Connecting tube 3, air valve seat 4, steel ball 5 of calming the anger, regulating bolt 6；One end of connecting tube 3 is arranged on air valve seat 4
On inwall, the other end of connecting tube 3 is connected with the side wall of the escape pipe of contained eustachian tube 1；Connecting tube 3 is connected with air valve seat 4
The inwall of one end be set to curved surface；Air valve seat 4 is columnar structured, and air valve seat 4 is internally provided with regulating bolt 6；Calm the anger steel
Ball 5 is placed in curved surface.
Wherein, the side wall of the escape pipe of contained eustachian tube 1 is communicated with constant-voltage equipment 2, and constant-voltage equipment 2 is used for regulating and controlling pharynx drum
The outlet air pressure of pipe inflator 1, and so that outlet stable gas pressure is in the range of an approximately constant；Constant-voltage equipment 2 includes：Even
Adapter 3, air valve seat 4, steel ball 5 of calming the anger, regulating bolt 6, the side wall of the escape pipe of the insertion contained eustachian tube 1 of connecting tube 3, when need
During the outlet air pressure of escape pipe to be increased, user can utilize regulating bolt 6 of the instrument extruding on 4 inwall of air valve seat,
And then regulating bolt 6 can extrude steel ball 5 of calming the anger, the inwall of the one end being connected with air valve seat 4 due to connecting tube 3 is set to curved surface,
In extrusion process, steel ball 5 of calming the anger can be progressed in curved surface, and is gradually in close contact with connecting tube 3, extrude connection with this
Gas inside pipe 3, and then increase the outlet air pressure of escape pipe；When the outlet air pressure for needing to reduce escape pipe, user can
Pulled outwards slow for the regulating bolt 6 on 4 inwall of air valve seat using instrument, as regulating bolt 6 is displaced outwardly, pressure
Extruding degree between the inwall of gas steel ball 5 and connecting tube 3 can also reduce, and what now the gas inside connecting tube 3 was subject to extrudes
Degree reduces, and then reduces the outlet air pressure of escape pipe；After regulating bolt to be moved 6 is finished so that contained eustachian tube 1 goes out
Gas air pressure meets using required air pressure size, and position of the regulating bolt 6 in air valve seat 4 will not be changed again easily, this
When, the outlet air pressure of contained eustachian tube 1 can be stablized in the range of an approximately constant.
In a kind of possible implementation of the utility model, the inwall of air valve seat 4 is provided with the first internal thread 7, adjusts
The outer wall of bolt 6 is provided with first external screw thread 8 supporting with the first internal thread 7.
Wherein, if air valve seat 4 and regulating bolt 6 are adopted thread connecting mode, the inwall of air valve seat 4 is provided with
One internal thread 7, the outer wall of regulating bolt 6 are provided with first external screw thread 8 supporting with the first internal thread 7, then user can be just
Sharp ground is controlled to the movement of regulating bolt 6, and now user is provided with several grooves in the afterbody of regulating bolt 6, by work
In tool insertion groove, then turning tool, and then rotation regulating bolt 6, you can regulating bolt 6 is moved in or out, is entered
And increase or reduce outlet air pressure.
In the alternatively possible implementation of the utility model, regulating bolt 6 is provided centrally with steam vent 9.
Wherein, the stable gas pressure for being provided centrally with steam vent 9, can keeping inside air valve seat 4 in regulating bolt 6, keeps away
Exempt from the air pressure inside air valve seat 4 when user moves regulating bolt 6, regulating bolt 6 is caused to hinder.
In the utility model in another possible implementation, this constant pressure contained eustachian tube also includes：Seal pipe 10,
Seal pipe 10 is wrapped on the outer wall of connecting tube 3, and one end of seal pipe 10 is connected with air valve seat 4.
Wherein, due to during air pressure adjustment, needing the sealing for ensureing device, therefore this constant pressure pharyngotympanic tube catheterization
Device also includes seal pipe 10, used as seal means；User when mounted, seal pipe 10 is arranged on the side wall of escape pipe,
And fluid sealant is set, when air pressure adjustment is carried out, good sealing effectiveness can be played.
In the utility model in another possible implementation, this constant pressure contained eustachian tube also includes：Spring 11, bullet
One end of spring 11 is fixed on the surface of steel ball 5 of calming the anger, and the other end of spring 11 is fixed on the center of regulating bolt 6.
Wherein, if directly calming the anger steel ball 5 carrying out air pressure adjustment, the speed of air pressure adjustment using regulating bolt 6
It is difficult to control, the speed that air pressure changes is difficult to control to, spring 11 is now set, will be calmed the anger steel ball 5, regulating bolt using spring 11
6 couple together, and can play cushioning effect, and in mobile regulating bolt 6, spring 11 can play cushioning effect, slow down and calm the anger
The translational speed of steel ball 5, is easy to user to be controlled.
In the utility model in another possible implementation, the outside of spring 11 is cased with rubber protecting jacket 12；Rubber
One end of protective case 12 is fixed on the surface of steel ball 5 of calming the anger, and the other end of rubber protecting jacket 12 is fixed on the table of regulating bolt 6
Face.
Wherein, as the both sides of spring 11 are susceptible to bend, if only by spring 11 will calm the anger steel ball 5, adjust spiral shell
Bolt 6 is coupled together, then the internal structure of this constant pressure contained eustachian tube can be caused not firm enough；Now in the outside peace of spring 11
Dress rubber protecting jacket 12, on the one hand can play certain fixation, place spring 11 and bend, on the other hand, due to
Rubber protecting jacket 12 has pliability, does not therefore also interfere with the compression of spring 11, and then does not interfere with air pressure adjustment.
In the utility model in another possible implementation, 5 inner hollow of steel ball of calming the anger.
Wherein, steel ball 5 of calming the anger is set to the spheroid of inner hollow, can effectively mitigates this constant pressure contained eustachian tube
Weight, and in squeeze adjustments bolt 6, the resistance that steel ball 5 of calming the anger gives can also reduce.
Finally it should be noted that：Above example only in order to the technical solution of the utility model to be described, rather than a limitation；
Although being described in detail to the utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
Which still can be modified to the technical scheme described in previous embodiment, or to which part or all technical characteristic
Carry out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from the utility model embodiment
The scope of technical scheme.
