Description

Single cavity double sac bronchial cannula
Technical field
The invention belongs to medical apparatus, be specifically related to a kind of bronchus plug-in unit, be mainly used in adult and child's thoracic surgery One-lung ventilation needed for middle pulmonary sequestration.
Background technology
Due to the fast development of less invasive techniques, increasing thoracic surgery needs One-lung ventilation, at present, and one-lung ventilation Isolating frequently with double lumen endobronchial tube, Dual-channel tracheal cannula is relatively thick because of caliber, and operation easier is big, easily causes respiratory tract Complication, it addition, for infant, owing to its trachea breathed is thinner, it is impossible to insert thicker intubating, 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, Must increase an air bag in bronchus, be used for blocking bronchus and realize one-way ventilating, current this cannula inner diameter is both greater than 6.5mm, less than loading air bag in the pipe of 6.5mm, the most just cannot produce, and ultimately results in infant patient available without pipe;No Can meet clinical needs, it is therefore necessary to research and development one 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.
Summary of the invention
The problem to be solved in the present invention be to provide one can double pulmonary ventilation, again can one-lung ventilation, catheter diameter has Different model between 3.0mm-10.0mm, can meet adult and the bronchial cannula of infant use simultaneously.
For solving the problems referred to above, the technical solution used in the present invention is: single-chamber double bolloon bronchial cannula, leads including trachea Pipe, catheter adapter, tracheal tampon, bronchial catheter, bronchial cuff, tracheal tampon charge valve and bronchial cuff charge valve, Endotracheal tube is provided with scale, and the endotracheal tube side between described tracheal tampon and bronchial cuff is provided with an endotracheal tube Side opening, the bronchial catheter in described bronchial cuff is provided with bronchial catheter side opening, and bronchial catheter side opening is provided with bullet Property film, described elastica can cave inward and is close to the inwall of bronchial catheter in the case of bronchial cuff is inflated, thus seals Closing bronchial catheter, described tracheal tampon connects with tracheal tampon gas tube, and described bronchial cuff is inflated with bronchial cuff Pipe connects.
Further, the internal diameter of described endotracheal tube is 3.0-10.0mm, due to by current single-chamber bronchial cannula at conduit Set air bag in tube chamber to make in main bronchus cuff inner conduit wall, design side opening and apply elastica to close, so a gas It is thinner that pipe can do, and uses current single-chamber bronchial cannula and be difficult to when internal diameter is less than 6mm.
Further, the side opening in described main bronchus cuff is oval or circular, and oval or circle is more beneficial for Elastica is sunk in conductive pipe when main bronchus sleeve bag gas-filling, effective occlusion catheter far-end.
The invention have the advantage that owing to having made air bag inner catheter side opening into by setting air bag in existing single-chamber bronchial cannula The structure of elastica is fixed in upper covering, reduces manufacture difficulty, and uses single cavity double sac to reach the lung isolation effect of single-chamber three capsule Really, internal diameter can be done make the different sizes such as 3.0mm-10.0mm by intubating, needed for meeting different age group patient's one-lung ventilation, Not only can effectively reduce and intubate the injury to patient, moreover it is possible to significantly drop production difficulty, the present invention can be not only used for unilateral ventilation, also May be used for bilateral ventilation, it is most important that one-lung ventilation in adult and infant thoracic surgery can be met simultaneously and use, significantly Improve universal performance.

Detailed description of the invention
Referring to Fig. 1, the single-chamber double bolloon bronchial cannula of the present invention, including endotracheal tube 2, catheter adapter 1, air pipe sleeve Capsule 8, bronchial catheter 10, bronchial cuff 11, tracheal tampon charge valve 5 and bronchial cuff charge valve 6, on endotracheal tube 2 Being provided with scale, the side of the endotracheal tube 2 between described tracheal tampon 8 and bronchial cuff 11 is provided with an endotracheal tube side opening 8, the bronchial catheter 10 in described bronchial cuff 11 is provided with bronchial catheter side opening 12, and bronchial catheter side opening 12 sets Flexible film 13, described elastica 13 can cave inward in the case of bronchial cuff 11 is inflated and be close to bronchial catheter 10 Inwall, thus close bronchial catheter 10, described tracheal tampon 8 connects with tracheal tampon gas tube 3, described bronchial cuff 11 Connect with bronchial cuff gas tube 7;The upper end of described tracheal tampon gas tube 3 and bronchial cuff gas tube 7 is equipped with pressure Power display ball 4 and sleeve bag gas-filling valve.
The internal diameter of described endotracheal tube 2 is 3.0-10.0mm.
Described bronchial catheter side opening 12 is oval or circular, by bronchial cuff gas tube 7 to bronchus set When capsule 11 is inflated, the lower elastica 13 of bronchial cuff 11 air pressure promotion is to bronchial catheter 10 tube chamber internal projection, at bronchus set Before capsule 11 effectively closes bronchus, springform 13 closes bronchial catheter 10 tube chamber in advance, is conducive to effectively sealing bronchus Conduit.
During Clinical practice, intubate oral insert trachea, when bronchial cuff 11 arrives the suitable position of human body bronchus When putting, close trachea by tracheal tampon gas tube 3 to tracheal tampon 8 inflation, to patient ventilation in pipe, verify two pulmonary ventilation Situation, if without exception, then bronchial cuff 11 is inflated, along with bronchial cuff 11 is intrinsic pressure by bronchial cuff gas tube 7 Power is gradually increased, and springform 13 is gradually prominent in bronchial lumen, first closes bronchial catheter tube chamber, continues bronchial cuff 11 inflations, after bronchial cuff 11 effectively closes bronchus, stop inflation, verify two pulmonary respiration situations, need as reached clinical Ask, then achieved the purpose of one-lung ventilation by endotracheal tube side opening 9.
When needs bilateral is ventilated, by bronchial cuff charge valve 6 by evacuating air in bronchial cuff 11, allow elasticity Mould 13 bounces back, and bronchial catheter 10 tube chamber is open, thus realizes bilateral pulmonary ventilation.
The body of the present invention can produce left and right two kinds and the pipe number of the various internal diameter of 3.0-10.0, and length can be according to not With age patients design, according to lung insulation request, select its suitable class, select suitably pipe number to use according to patient age.
Another embodiment of the present invention, the bronchial catheter 10 in described bronchial cuff 11 disconnects one section, disconnects Part spring-backed quill 14 connects, and when bronchial cuff 11 is not inflated, spring-backed quill 14 internal diameter is close to bronchial catheter 10, permissible Ventilation, after bronchial cuff 11 is inflated, spring-backed quill 14 can be narrowed down to 0 by compression internal diameter, and equally closure bronchus is led Pipe, it is achieved unilateral ventilation.
