Abstract
The utility model relates to a single lumen tracheal catheter for a thoracic surgery and the single lumen tracheal catheter comprises a tracheal catheter main body. A front end of the tracheal catheter main body is provided with a tracheal cuff; and the tracheal catheter cuff is connected with a first pressure inflation valve via a first inflation pipe. The single lumen tracheal catheter for thoracic surgery is characterized in that the tracheal catheter main body in front of the tracheal catheter cuff is further provided with a long bronchia cuff along an axis direction of the tracheal catheter main body; the long bronchia cuff is connected with a second pressure inflation valve via a second inflation pipe; and the tracheal catheter main body between the tracheal catheter cuff and the long bronchia cuff is provided with at least one vent hole. The single lumen tracheal catheter for thoracic surgery is simple and compact in structure and convenient in usage; compared with common double-lumen bronchia tracheal catheter, airway pressure is lower when air is ventilated with one lung; compared with a bronchia tracheal catheter packer, the single-lumen tracheal catheter for thoracic surgery is simple in manufacturing technology and low in cost; and besides, the single-lumen tracheal catheter for thoracic surgery possesses an outstanding advantage of convenient application for children patients.
Description
Technical field
This utility model relates to a kind of endotracheal tube, and specifically a kind of thoracic surgery single-lumen bronchial tube belongs to technical field of medical instruments.
Background technology
Thoracic surgery often need be good for side one-lung ventilation and the flat lung of Ipsilateral lung and the operation of drum lung, need carry out two pulmonary ventilation after operation finishes again.Implement one-lung ventilation at present and mainly contain employing double lumen endobronchial tube and two kinds of methods of bronchus blanking plug, they respectively have superiority, and also respectively are weak: pressure is higher during the double lumen endobronchial tube one-lung ventilation, may cause strong side injury of lung; Cost is bigger during bronchus blanking plug one-lung ventilation, needs bronchoscope location.And for pediatric patient, no matter be the ventilation means that adopts double lumen endobronchial tube or bronchus blanking plug, all use because of comparatively narrow thin being difficult to of air flue.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and providing performs the operation in a kind of thoracic cavity uses single-lumen bronchial tube, and it is simple and compact for structure, and is easy to use, also can conveniently implement at pediatric patient.
The technical scheme that provides according to this utility model: operation single-lumen bronchial tube in the thoracic cavity, comprise the endotracheal tube main body, described endotracheal tube body front end is provided with tracheal tampon, this tracheal tampon is connected with the first pressure inflatable valve by first gas tube, it is characterized in that: also be provided with one on the endotracheal tube main body in described tracheal tampon the place ahead along the tracheal tampon of drawing money on credit of endotracheal tube main body axis direction, this tracheal tampon of drawing money on credit is connected with the second pressure inflatable valve by second gas tube; Described tracheal tampon and the endotracheal tube main body of drawing money on credit between the tracheal tampon are provided with at least one passage.
As further improvement of the utility model, the described little rear end of tracheal tampon front end of drawing money on credit is big, and the tracheal tampon front end of drawing money on credit is positioned at bronchus in use, and the tracheal tampon rear end of drawing money on credit is positioned at the trachea of knuckle top in use.
As further improvement of the utility model, described passage is a plurality of, and they are circumferentially uniform on the endotracheal tube main body.
As further improvement of the utility model, the described first pressure inflatable valve and the second pressure inflatable valve are provided with distinguishing identifier.
As further improvement of the utility model, 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.
This utility model compared with prior art, advantage is:This utility model is simple and compact for structure, and is easy to use, compares with common double lumen endobronchial tube, and airway pressure is lower during one-lung ventilation; Compare with the bronchus blanking plug, manufacturing process is simple, and is with low cost; In addition, this utility model also has the outstanding advantage that can also can conveniently implement on pediatric patient.

The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: operation mainly is made up of the first pressure inflatable valve, 1 first gas tube 2, endotracheal tube main body 3, the second pressure inflatable valve 7 and second gas tube 8 with single-lumen bronchial tube in the thoracic cavity among the embodiment.
As shown in Figure 1 and Figure 2, described endotracheal tube main body 3 front ends are provided with tracheal tampon 4, and this tracheal tampon 4 is connected with the first pressure inflatable valve 1 by first gas tube 2; Also be provided with one on the endotracheal tube main body 3 in described tracheal tampon 4 the place aheads along the tracheal tampon 6 of drawing money on credit of endotracheal tube main body 3 axis directions, this tracheal tampon 6 of drawing money on credit is connected with the second pressure inflatable valve 7 by second gas tube 8; Described tracheal tampon 4 and the endotracheal tube main body 3 of drawing money on credit between the tracheal tampon 6 are provided with a plurality of circumferential uniform passages 5.
In this utility model, the described tracheal tampon 6 of drawing money on credit preferably is arranged to the big calabash shape version in the little rear end of front end, and tracheal tampon 6 front ends of drawing money on credit are positioned at bronchus in use, and tracheal tampon 6 rear ends of drawing money on credit are positioned at the trachea of knuckle top in use.
In this utility model, for easy to operate, the described first pressure inflatable valve 1 and the second pressure inflatable valve 7 are provided with distinguishing identifier.Described distinguishing identifier can be different colours and/or profile and/or literal.
During concrete the application, endotracheal tube of the present utility model rear end connects respirator by the respirator interface, and the endotracheal tube front end inserts in the trachea (shown in Figure 2), 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 endotracheal tube front end is inserted the single lung of strong side, adjust the endotracheal tube placed-depth, make tracheal tampon 6 front ends of drawing money on credit be positioned at the bronchus of the single lung of strong side and the trachea that the rear end is positioned at the knuckle top, fixedly endotracheal tube; Give tracheal tampon 4 inflations by the first pressure inflatable valve 1, first gas tube 2, tracheal tampon 4 is heaved, sealing endotracheal tube and trachea gap; Give tracheal tampon 6 inflations of drawing money on credit by the second pressure inflatable valve 7, second gas tube 8, the tracheal tampon 6 of drawing money on credit is heaved, the bronchus gap (shown in Figure 3) of the single lung of sealing endotracheal tube and strong side, and can give strong side one-lung ventilation this moment by respirator.
When the two pulmonary ventilation of needs, tracheal tampon 6 venting of drawing money on credit are flat to be fallen, and respirator can be given both sides pulmonary ventilation (shown in Figure 4) simultaneously by the passage 5 on the endotracheal tube main body 3 and endotracheal tube master chamber.
