Description

Single cavity double sac bronchial cannula
Technical field
The invention belongs to medical apparatus, and in particular to a kind of bronchus plug-in unit, is mainly used for adult and children's thoracic surgery One-lung ventilation needed for middle pulmonary sequestration.
Background technology
Due to the fast development of minimal invasive techniques, more and more thoracic surgeries need One-lung ventilation, at present, one-lung ventilation Isolated frequently with dual cavity bronchus vessel, for Dual-channel tracheal cannula because caliber is thicker, operation difficulty is big, be easy to cause respiratory tract Complication, in addition, for infant, since the tracheae of its breathing 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, current this cannula inner diameter is both greater than 6.5mm, can not load air bag in the pipe less than 6.5mm, also can not just produce, ultimately result in infant patient and can use without pipe;No It can meet clinical needs, it is therefore necessary to research and development one kind is easy to operate easily, is readily produced manufacture, and clinical complication is few, and It can meet the trachea cannula of different age group patient's one-lung ventilation demand.
The content of the invention
The problem to be solved in the present invention be to provide one kind can double pulmonary ventilation and one-lung ventilation, catheter diameter have Different model between 3.0mm-10.0mm, can meet the bronchial cannula that adult and infant use at the same time.
To solve the above problems, the technical solution adopted by the present invention is:Single-chamber double bolloon bronchial cannula, including tracheae are led Pipe, pipe joint, tracheal tampon, bronchial catheter, bronchial cuff, tracheal tampon charge valve and bronchial cuff charge valve, Tracheal catheter is equipped with scale, and the tracheal catheter side between the tracheal tampon and bronchial cuff is equipped with a tracheal catheter Side opening, the bronchial catheter in the bronchial cuff are equipped with bronchial catheter side opening, and bronchial catheter side opening is equipped with bullet Property film, the elastic membrane can be recessed inwardly in the case where bronchial cuff is inflated and be close to the inner wall of bronchial catheter, so as to seal Bronchial catheter is closed, the tracheal tampon is connected with tracheal tampon gas tube, and the bronchial cuff is inflated with bronchial cuff Pipe connects.
Further, the internal diameter of the tracheal catheter is 3.0-10.0mm, due to by current single-chamber bronchial cannula in conduit Set air bag in tube chamber to make into design side opening in main bronchus cuff inner conduit wall and closed using elastic membrane, so branch gas Pipe can be done thinner, and internal diameter is used current single-chamber bronchial cannula and is difficult to realize when being less than 6mm.
Further, the main bronchus covers intracapsular side opening for ellipse or circular, and ellipse or circle are more advantageous to Elastic membrane is sunk in main bronchus sleeve bag gas-filling into conduit, effective occlusion catheter distal end.
It is an advantage of the invention that:Air bag inner catheter side opening is made into since air bag will be set in existing single-chamber bronchial cannula The structure of the upper fixed elastic membrane of covering, reduces manufacture difficulty, and reaches the lung isolation effect of three capsule of single-chamber using single cavity double sac Intubation, can be done internal diameter and make the different sizes such as 3.0mm-10.0mm by fruit, be met needed for different age group patient's one-lung ventilation, It not only can effectively reduce injury of the intubation to patient, moreover it is possible to significantly drop production difficulty, the present invention can be not only used for unilateral ventilation, also It can be used for bilateral ventilation, it is most important that can meet that one-lung ventilation uses in adult and infant's thoracic surgery at the same time, significantly Improve universal performance.

Embodiment
Referring to Fig. 1, the single-chamber double bolloon bronchial cannula of the present invention, including tracheal catheter 2, pipe joint 1, air pipe sleeve Capsule 8, bronchial catheter 10, bronchial cuff 11, tracheal tampon charge valve 5 and bronchial cuff charge valve 6, on tracheal catheter 2 Equipped with scale, the side of the tracheal catheter 2 between the tracheal tampon 8 and bronchial cuff 11 is equipped with a tracheal catheter side opening 8, the bronchial catheter 10 in the bronchial cuff 11 is equipped with bronchial catheter side opening 12, is set on bronchial catheter side opening 12 Flexible film 13, the elastic membrane 13 can be recessed inwardly in the case where bronchial cuff 11 is inflated is close to bronchial catheter 10 Inner wall, so as to close bronchial catheter 10, the tracheal tampon 8 is connected with tracheal tampon gas tube 3, the bronchial cuff 11 Connected with bronchial cuff gas tube 7;The upper end of the tracheal tampon gas tube 3 and bronchial cuff gas tube 7 is equipped with pressure Power shows ball 4 and sleeve bag gas-filling valve.
The internal diameter of the tracheal catheter 2 is 3.0-10.0mm.
The bronchial catheter side opening 12 is ellipse or circular, by bronchial cuff gas tube 7 to bronchus set When capsule 11 is inflated, 11 air pressure of bronchial cuff promotes lower elastic membrane 13 to 10 tube chamber internal projection of bronchial catheter, in bronchus set Before capsule 11 effectively closes bronchus, springform 13 closes 10 tube chamber of bronchial catheter in advance, is conducive to effectively seal bronchus Conduit.
During Clinical practice, oral insert tracheae is intubated, when bronchial cuff 11 reaches the suitable position of human body bronchus When putting, closing tracheae is inflated to tracheal tampon 8 by tracheal tampon gas tube 3, to patient ventilation out of pipe, verifies two pulmonary ventilation Situation, if it is without exception, then bronchial cuff 11 is inflated by bronchial cuff gas tube 7, with 11 internal pressure of bronchial cuff Power gradually increases, and springform 13 is gradually prominent into bronchial lumen, first closes bronchial catheter tube chamber, continues to bronchial cuff 11 inflations, after bronchial cuff 11 effectively closes bronchus, stop inflation, verify two pulmonary respiration situations, and such as reaching clinical needs Ask, then the purpose of one-lung ventilation is realized by tracheal catheter 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 opens, so as to fulfill bilateral pulmonary ventilation.
The tube body of the present invention can produce the pipe number of left and right two categories and the various internal diameters of 3.0-10.0, and length can be according to not With age patients design, according to lung insulation request, its suitable class is selected, selects suitable pipe number to use according to patient age.
Another embodiment of the present invention, the bronchial catheter 10 in the bronchial cuff 11 disconnect one section, disconnect Part spring-backed quill 14 connects, and when bronchial cuff 11 is non-aerating, 14 internal diameter of spring-backed quill, can be with close to bronchial catheter 10 Ventilation, after bronchial cuff 11 is inflated, spring-backed quill 14 can narrow down to 0 by compression internal diameter, can equally block bronchus and lead Pipe, realizes unilateral ventilation.
