The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the cover of three among embodiment capsule double lumen endobronchial tube mainly is made up of the first pressure inflatable valve, 1 first gas tube 2, double lumen endobronchial tube main body 3, second gas tube 4, the second pressure inflatable valve 5, the 3rd pressure inflatable valve 6 and the 3rd gas tube 7.
As shown in Figure 1 and Figure 2, the front end of the single lumen catheter body 3b of described double lumen endobronchial tube main body 3 is provided with bronchial cuff 11, and this bronchial cuff 11 is connected with the first pressure inflatable valve 1 by first gas tube 2; The double lumen tube body 3a of described double lumen endobronchial tube main body 3 is provided with tracheal tampon 8, and this tracheal tampon 8 is connected with the second pressure inflatable valve 5 by second gas tube 4; The single lumen catheter body 3b of described double lumen endobronchial tube main body 3 also is provided with cover capsule 10 on the knuckle, and cover capsule 10 is positioned at after the bronchial cuff 11 on this knuckle, and cover capsule 10 is connected with the 3rd pressure inflatable valve 6 by the 3rd gas tube 7 on the knuckle; Double lumen endobronchial tube main body 3 on the described knuckle between cover capsule 10 and the tracheal tampon 8 is provided with passage 9.
As shown in Figure 1, among this utility model embodiment, described passage 9 is arranged on the single lumen catheter body 3b of double lumen endobronchial tube main body 3, and passage 9 is a plurality of, and described a plurality of passages 9 are circumferentially uniform on the single lumen catheter body 3b of double lumen endobronchial tube main body 3.
In this utility model, for easy to operate, on the described first pressure inflatable valve 1, the second pressure inflatable valve 5 and the 3rd pressure inflatable valve 6 be provided with distinguishing identifier.Described distinguishing identifier is different colours, or different profile, or different literals, or different colours and profile, or different colours and literal, or different profile and literal, or different colours, profile and literal.
During concrete the application, three cover capsule double lumen endobronchial tube rear ends of the present utility model connect respirator by the respirator interface, and front end inserts in patient's trachea, can carry out normal two pulmonary ventilation this moment.
When needs are good for the side one-lung ventilation, adopt location tube core guiding, the single lumen catheter body 3b front end of three cover capsule double lumen endobronchial tubes is inserted strong side lung A, adjust placed-depth, make bronchial cuff 11 be positioned at the bronchus of strong side lung A, and cover capsule 10 is positioned at the trachea of knuckle top on the knuckle, fixes three cover capsule double lumen endobronchial tubes; Give bronchial cuff 11 inflations by the first pressure inflatable valve 1, first gas tube 2, bronchial cuff 11 is heaved, and the single lumen catheter body 3b of three cover capsule double lumen endobronchial tubes and the gap between the strong side lung A bronchus are blocked; Give tracheal tampon 8 inflations by the second pressure inflatable valve 5, second gas tube 4, tracheal tampon 8 is heaved, and the double lumen tube body 3a of three cover capsule double lumen endobronchial tubes and the gap between the trachea are blocked; To cover capsule 10 inflations on the knuckle, cover capsule 10 is heaved on the knuckle, and the single lumen catheter body 3b of three cover capsule double lumen endobronchial tubes and the gap between the trachea are blocked (shown in Figure 2) by the 3rd pressure inflatable valve 6, the 3rd gas tube 7; Can give strong side lung A ventilation this moment by respirator, and Ipsilateral lung B keeps flat lung state.
When needs keep strong side lung A one-lung ventilation to put the tubulose attitude constant, when needing to carry out two pulmonary ventilation simultaneously, fall cover capsule 10 venting on the knuckle is flat, respirator also can be given Ipsilateral lung B ventilation (shown in Figure 3) by the passage 9 on the double lumen endobronchial tube main body 3 when giving strong side lung A ventilation like this.
But under some urgent rescue situation, the wrong situation of pipe can occur putting, namely the single lumen catheter body 3b front end of three cover capsule double lumen endobronchial tubes has been inserted Ipsilateral lung B, may delay the rescue time if reorientate.It is shown in Figure 5 that this moment, this utility model can cooperate bronchus blanking plug 12() the strong side lung A one-lung ventilation of realization, concrete operations are that bronchus blanking plug 12 is penetrated three cover capsule double lumen endobronchial tubes, make the obstruction air bag 13 of bronchus blanking plug 12 front ends enter the single lumen catheter body 3b of three cover capsule double lumen endobronchial tubes and be positioned at passage 9 the place aheads, give the bronchus blanking plug 12 inflations, obstruction air bag 13 is heaved, stopping up air bag 13 blocks the three single lumen catheter body 3b that overlap the capsule double lumen endobronchial tubes, three cover capsule double lumen endobronchial tubes are operated according to state shown in Figure 3 then, and can put the strong side lung A one-lung ventilation of realization under the pipe error situation this moment.
