Description
Technical field
This utility model belongs to medical apparatus, and in particular to a kind of bronchus plug-in unit, is mainly used in adult and child thoracic cavity
One-lung ventilation in operation needed for pulmonary sequestration.
Background technology
Due to the fast development of less invasive techniques, increasing thoracic surgery needs One-lung ventilation, at present, one-lung ventilation
Isolated frequently with double lumen endobronchial tube, Dual-channel tracheal cannula is thicker because of caliber, operation difficulty is big, easily causes respiratory tract
Complication, in addition, for infant, due to the trachea which breathes it is thinner, it is impossible to the thicker intubation of insertion, in existing product
Also there is single-chamber bronchial cannula, but this single-chamber bronchial cannula should realize two-way ventilation, if realizing one-way ventilating again,
An air bag must be increased in bronchus, one-way ventilating is realized for blocking bronchus, this cannula inner diameter is both greater than at present
6.5mm, less than loading air bag in the pipe of 6.5mm, also cannot just produce, and ultimately result in infant patient available without pipe；No
Can meet clinical needs, it is therefore necessary to which research and development one kind is simple to operate easily, be readily produced manufacture, and clinical complication is few, and
The tracheal intubation of different age group patient's one-lung ventilation demand can be met.
The content of the invention
Problem to be solved in the utility model be provide one kind can double pulmonary ventilation, and can one-lung ventilation, catheter diameter
There is different model between 3.0mm-10.0mm, the bronchial cannula that adult and infant are used can be met simultaneously.
To solve the above problems, the technical solution adopted in the utility model is：Single-chamber double bolloon bronchial cannula, including gas
The inflation of pipe conduit, catheter adapter, tracheal tampon, bronchial catheter, bronchial cuff, tracheal tampon charge valve and bronchial cuff
Valve, endotracheal tube are provided with scale, and the endotracheal tube side between the tracheal tampon and bronchial cuff is provided with a trachea
Conduit side opening, the bronchial catheter in the bronchial cuff are provided with bronchial catheter side opening, set on bronchial catheter side opening
Flexible film, the elastica can cave inward in the case of bronchial cuff inflation and be close to the inwall of bronchial catheter, from
And bronchial catheter is closed, the tracheal tampon connected with tracheal tampon gas tube, the bronchial cuff and bronchial cuff
Gas tube is connected.
Further, the internal diameter of the endotracheal tube be 3.0-10.0mm, due to by current single-chamber bronchial cannula in conduit
Set air bag to make into side opening to be designed in main bronchuss cuff inner conduit wall and is closed using elastica in tube chamber, so a gas
It is thinner that pipe can do, and internal diameter is used current single-chamber bronchial cannula when being less than 6mm and is difficult to.
Further, the main bronchuss cover intracapsular side opening and are more beneficial for for oval or circle, ellipse or circle
Elastica is sunk into conduit in main bronchuss sleeve bag gas-filling, effective occlusion catheter distal end.
The utility model has the advantages that：Air bag inner catheter is made into as air bag will be set in existing single-chamber bronchial cannula
The structure of fixed elastica is covered on side opening, manufacture difficulty is reduced, and using single cavity double sac reach the lung of three capsule of single-chamber every
From effect, intubation can be done internal diameter and make the different sizes such as 3.0mm-10.0mm, meet different age group patient's one-lung ventilation
It is required, not only can effectively reduce injury of the intubation to patient, moreover it is possible to significantly drop production difficulty, this utility model can be not only used for list
Side is ventilated, and can be also used for bilateral ventilation, it is most important that can meet one-lung ventilation in adult and infant thoracic surgery simultaneously
Use, substantially increase universal performance.

Specific embodiment
Refer to Fig. 1, single-chamber double bolloon bronchial cannula of the present utility model, including endotracheal tube 2, catheter adapter 1, gas
Pipe box capsule 8, bronchial catheter 10, bronchial cuff 11, tracheal tampon charge valve 5 and bronchial cuff charge valve 6, endotracheal tube
2 are provided with scale, and the side of the endotracheal tube 2 between the tracheal tampon 8 and bronchial cuff 11 is provided with an endotracheal tube
Side opening 8, the bronchial catheter 10 in the bronchial cuff 11 are provided with bronchial catheter side opening 12, bronchial catheter side opening 12
Elastica 13 is provided with, the elastica 13 can cave inward in the case of the inflation of bronchial cuff 11 and be close to bronchial catheter
10 inwall, so as to close bronchial catheter 10, the tracheal tampon 8 is connected with tracheal tampon gas tube 3, the bronchus set
Capsule 11 is connected with bronchial cuff gas tube 7；The upper end of the tracheal tampon gas tube 3 and bronchial cuff gas tube 7 is all provided with
There is pressure to show ball 4 and sleeve bag gas-filling valve.
The internal diameter of the endotracheal tube 2 is 3.0-10.0mm.
The bronchial catheter side opening 12 is oval or circular, is passing through bronchial cuff gas tube 7 to bronchus set
When capsule 11 is inflated, 11 air pressure of bronchial cuff promotes lower elastica 13 to 10 tube chamber internal projection of bronchial catheter, in bronchus set
Before the effectively closing bronchus of capsule 11, springform 13 closes 10 tube chamber of bronchial catheter in advance, is conducive to effectively sealing bronchus
Conduit.
During Clinical practice, the oral insert trachea of intubation, when bronchial cuff 11 reaches the suitable position of human body bronchus
When putting, by tracheal tampon gas tube 3 to the inflation closing trachea of tracheal tampon 8, from pipe to patient ventilation, two pulmonary ventilation are verified
Situation, if without exception, then is inflated to bronchial cuff 11 by bronchial cuff gas tube 7, with bronchial cuff 11 it is intrinsic pressure
Power gradually increases, and springform 13 gradually to prominent in bronchial lumen, first closed bronchial catheter tube chamber, continued to bronchial cuff
11 inflations, after the effectively closing bronchus of bronchial cuff 11, stop inflation, verify two pulmonary respiration situations, such as reach clinical need
Ask, then the purpose of one-lung ventilation is realized by endotracheal tube side opening 9.
When needing bilateral to ventilate, by bronchial cuff charge valve 6 by evacuating air in bronchial cuff 11, elasticity is allowed
Mould 13 bounces back, and 10 tube chamber of bronchial catheter is opened, so as to realize bilateral pulmonary ventilation.
Body of the present utility model can produce the pipe number of left and right two kinds of classifications and the various internal diameters of 3.0-10.0, and length can be according to
According to all ages and classes patients design, according to lung insulation request, its suitable class is selected, select suitable pipe number to make according to patient age
With.
Another embodiment of the present utility model, the bronchial catheter 10 in the bronchial cuff 11 disconnect one section,
Breaking part spring-backed quill 14 connects, and when bronchial cuff 11 is non-aerating, 14 internal diameter of spring-backed quill is close to bronchial catheter 10,
Can ventilate, after bronchial cuff 11 is inflated, spring-backed quill 14 can be narrowed down to 0 by compression internal diameter, can equally block a gas
Pipe conduit, realizes unilateral ventilation.
