Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples：Adjustable plugging type artificial trachea as shown in fig. 1
Casing is equipped with the pipe shaft 3 of hard, usually the metal tube of slightly curved song, and pipe shaft head and the tail penetrate through, and the periphery of pipe shaft one end is fixed with
Pipe cap 2, pipe shaft, which is inserted in throat's body, connects tracheae, and pipe cap stays in vitro, and diameter is more than pipe shaft, can prevent pipe shaft from sliding into body
It is interior.
Sealing pipe close 1 is equipped in the pipe shaft of 2 one end of pipe cap.The sealing pipe close 1 of the present invention, which plays, blocks artificial trachea
Effect, also acting as can be taking human as the effect for adjusting the unimpeded degree of tracheae.
Such as Fig. 2,3, the sealing pipe close 1 is mutually nested outer plug 4 and Nei Sai 8, and outer plug 4 and Nei Sai 8 is that inner end is small
The big rounding mesa-shaped in outer end, the lateral wall of interior plug are bonded with the madial wall of outer plug.The effect of outer plug is fastened with pipe shaft 3, interior plug
Internal rotating can be filled in outside.
Pipe shaft inner wall in pipe cap one end is equipped with and axially vertical corrugated curved surface.In the artificial trachea of corresponding position
Wall is equipped with corrugated curved surface, and the protrusion of corrugated curved surface and rubber gasket is made to be staggered, and to enhance the outer fastening filled in, prevents outer
Plug loosens.To increase the frictional resistance between outer plug 4 and pipe shaft inner wall, prevent pipeline air pressure inside from crossing the abjection of ambassador's pipe close.
Such as Fig. 4,5, the interior plug 8 is the inner plug body 11 with full circle lateral wall for part on cross section, carries concentric
The fan-shaped radian of fan-shaped interior plug chamber 10, inner plug body 11 is 180 °~190 °, and interior plug chamber 10 is axially through interior plug 8.
Interior plug chamber is set as side, inner plug body is the other side, relative to use multigroup cavity and entity to structure for,
The stroke of adjusting is big, is easy to grasp, manufacture technology is simple；And it is big to play filtering using the structure of multigroup cavity and entity pair
Impurity and fibre object enter the effect of tracheae.
Interior plug chamber and inner plug body can be column, can also be helical form, and columnar ventilatory effect is slightly better than helical form.
It is column in Fig. 4, i.e., the interface of interior plug chamber and inner plug body is in one plane.
It is described it is interior plug 8 top surface be integrally formed with it is outwardly directed carry handle 9, carry handle with it is interior plug 11 circle centre position of inner plug body connect
It connects, junction is rod-shaped.Interior plug can be taken out and be filled in by carrying handle 9, and interior plug is rotated plug inside outside, adjusted
The size of vent openings.
Such as Fig. 2,3, the outer plug 4 is equipped with outer plug closedtop 6 in top surface, and the outer plug closedtop 6 is sector, and circle centre position is equipped with and carries
The concentric sector of handle slot 12.It is to carry handle 9 to merge out space to carry handle slot 12, to propose the dynamic interior plug rotation of grip strip, prevents the rotation of interior plug
Turn to be stopped by outer plug closedtop.
The fan-shaped angle of outer plug closedtop 6 is more than or equal to the segment angle of interior plug chamber, is less than+10 ° of the segment angle of interior plug chamber, outside
The rest part for filling in top surface is opening, and the fan angle of outer plug closedtop is slightly larger than interior plug chamber.
Outside plug closedtop 6 with the boundary edges on outer plug chamber cross section, the bottom edge of concordant outer plug closedtop 6 is provided with outward
The flexible one-way valve 13 that cavity direction stretches out 2~4mm is filled in, opening is fully sealed when playing the role of closure, when intracavitary negative pressure, with
Ensure to cover interior plug chamber with leaving no gaps in complete block.
Inwardly plug cavity direction is equipped at the top end opening of plug chamber, along the edge of interior plug chamber and inner plug body stretch out 2~4mm inside
Flexible one-way valve 13, when playing the role of closure, opening is fully sealed when positive intraluminal pressure.
The circular arc outer end face and side wall airtight connection of outer plug closedtop 6, i.e., the outer outer peripheral sidewall filled in are a complete convolutions
It is whole, meanwhile, the side wall of interior plug is also that a complete convolution is whole, is conducive to the integral strength for keeping outer plug and interior plug.
In order to compensate for inner plug body to tracheal tube the space occupied, pipe shaft 2 is that outer end is gradually big round table-like in pipe cap part,
The unilateral drift angle of round platform side wall is 0~20 °, actually expands the internal diameter of year tracheal tube, improves ventilation fluency.Pipe
The unilateral drift angle of round platform side wall is consistent with the unilateral drift angle of round platform side wall of outer cock body at the top of body or is slightly less than the round platform of outer cock body
The unilateral drift angle of side wall, to ensure being fastenedly connected for outer cock body.
In order to further strengthen the connection tightness of outer cock body, the lateral wall of the outer plug 4 is with axis perpendicular equipped with convex
For the rubber gasket 7 of lateral wall.Preferably, the rubber gasket 7 is equipped with 2 circles or 3 circles.The rubber gasket 7 of protrusion is conducive to
Reinforce the local pressure with tracheal tube madial wall, increasing friction force reinforces bonding strength.If necessary, and convenient for removing more
It changes.
