The bottom of body 5 and along the length of catheter body 5 to arranged two；Gas tube 3 (3a and 3b are expressed as in the figure) connection
It is used to carry out inflation/deflation to air bag 6 (being expressed as 6a and 6b in figure) in air bag 6 (being expressed as 6a and 6b in figure)；The humidification fluid is led
Pipe 4 and the endoporus of catheter body 5, which are mutually common in guide tube body 5, imports humidification fluid；In the insertion patients with respiratory tract of catheter body 5
Afterwards, catheter body 5 is fixed in respiratory tract by being inflated into air bag 6 (being expressed as 6a and 6b in figure), alternately use
Two air bags 6 (6a and 6b are expressed as in figure), are avoided that tissue ischemia, necrosis and infection that same position oppression is caused etc.
Complication, the gas tube 3 (3a and 3b are expressed as in figure) is two, and two gas tubes 3 (3a and 3b are expressed as in figure) are one by one
Corresponding to be connected to air bag 6 (6a and 6b are expressed as in figure), two gas tubes 3 (3a and 3b are expressed as in figure) pass through from the outside to the core
The upper portion side wall of catheter body 5 simultaneously extends downward into corresponding air bag 6 (6a and 6b are expressed as in figure) along the inwall of catheter body 5
Place；Elastic buffer bag is equipped with two gas tubes 3 (3a and 3b are expressed as in figure), and elastic buffer bag passes through gas tube 3
(3a and 3b are expressed as in figure) communicates with corresponding air bag 6 (6a and 6b are expressed as in figure), and elastic buffer bag bulges after inflation, and profit
The gas in air bag 6 (being expressed as 6a and 6b in figure) is kept certain pressure with its resilience, improve air bag 6 and (be expressed as in figure
6a and 6b) position stability between respiratory tract, humidifying fluid catheter 4 is connected to after humidification fluid supply arrangement, can be according to trouble
Humidifying is carried out the need for person to its respiratory tract, the humidifying fluid catheter 4 passes through upper portion side wall and the edge of catheter body 5 from the outside to the core
The inwall of catheter body 5 is extended in the bottom of catheter body 5, the present embodiment, using at 1/2 length of catheter body 5 as boundary, is led
The top of tube body 5 is the upper semisection of catheter body 5, and the bottom of catheter body 5 is the lower semisection of catheter body 5, due to humidification fluid
Conduit 4 extends to the bottom of catheter body 5, therefore can play guiding function to humidification fluid, it is to avoid humidification fluid flows back.
In the present embodiment, the upper end of the catheter body 5 is provided with respirator joint 1, and two gas tubes 3 (are expressed as in figure
3a and 3b) upper end be equipped with gas-charging connection 2, convenient use, gas-charging connection 2 be provided be used for control gas tube 3 (in figure represent
For 3a and 3b) valve of opening and closing, the valve includes the valve seat that connect with gas tube 3 (3a and 3b are expressed as in figure) and rotation company
The check valve of valve seat is connected to, because check valve is rotationally connected with valve seat, therefore rotation check valve can make its inlet and outlet in valve
Switch between the inlet and outlet of seat, therefore gas is can only flow into air bag 6 (being expressed as 6a and 6b in figure) in inflation, deflate
When can only be flowed out from air bag 6 (6a and 6b are expressed as in figure), the switching fill, deflated need to only rotate check valve, check valve bag
The steel ball and spring for including valve body and being installed in valve body, valve body is rotationally connected with valve seat, valve body along its rotor shaft direction and fixed
There is a handle, handle stretches out in valve seat, be rotatable whole check valve by rotary handle, it is simple and quick.
In the present embodiment, the outer wall of the catheter body 5 is provided with the scale value for representing its length, and the scale value is with conduit
The tip of the lower end of body 5 is starting point, is easy to the length in accurate control catheter body 5 insertion patients with respiratory tract.
In the present embodiment, the bottom side of the wall of the catheter body 5 is provided with side gas outlet 7；The side gas outlet 7 is located at two
The lower section of air bag 6 (6a and 6b are expressed as in figure), when the lower end of catheter body 5 is blocked, can be carried by side gas outlet 7 for patient
For the passage of breathing, for Emergency use；The outlet of humidifying fluid catheter be located at two air bags 6 (6a and 6b are expressed as in figure) with
Under, side gas outlet more than 7.
In the present embodiment, the lower end of the catheter body is provided with dividing plate 11, by the dividing plate 11 by under catheter body
End endoporus is divided at least two airways, each airway and is equipped with a valve plate 8, and forming at least one can only outlet
Gas off-take 12 and at least one can only return-air return-air road 13, valve plate 8 is connected to dividing plate 11 by flexible conjoined 14, makes valve plate 8
Can be along flexible conjoined 14 upsets, catheter body inwall, which is provided with, to be used to carry out valve plate 8 spacing block 9, makes valve plate 8 can only be to
Interior or outside upset, what valve plate 8 can only inwardly be overturn, corresponding is return-air road 13, and the gas for patient to be breathed out is exported；Valve
What plate 8 can only outwards be overturn, corresponding is gas off-take 12, for patient's Invivo oxyger-supply, in the valve plate 8 in each gas off-take 12
The heart is the structure of diaphragm 10, and the material of diaphragm 10 is identical with catheter body, and the thickness of diaphragm 10 is not more than 0.1mm, for implantation
The patient of tracheal catheter, the hidden danger of current generally existing is that tracheal catheter is easily blocked by phlegm, although there is provided the energy of side gas outlet 7
The situation is tackled to a certain extent, but side gas outlet 7 relatively closely can even fit apart from respiratory tract inwall, poor reliability, this reality
Example is applied to separate the lower end endoporus of catheter body, and form can only oxygen donator one-way flow air flue, due to there is air-flow
Impetus, therefore only return-air road 13 can be caused to block, when there are all situations of blocking of return-air road 13, pass through lung ventilator pair
Valve plate 8 in gas off-take 12 is pressed, and the diaphragm 10 on valve plate 8 is ruptured under pressure, now gas off-take 12
Two-way ventilation, it is ensured that carry out Emergency Oxygen Supply in the case of being blocked in return-air road 13 for patient.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme, it all should cover among the claim of the present invention and the scope of specification.
