Description
Technical field
This utility model relates to a kind of double lumen endobronchial tube with local anesthesia function, belongs to technical field of medical instruments.
Background technology
Double lumen endobronchial tube is mainly used in lung isolation operation, and separated by the arranged on left and right sides pulmonary ventilation pathway of patient, alternative carries out one-lung ventilation.Double lumen endobronchial tube is inserted in patient's main bronchus during use, the ventilation of left and right bronchus system is temporarily isolated, patient can be applied general anaesthetic, for pulmonary surgery and carrying out of other related surgicals provide convenience by side or bilateral tube chamber inhalation anesthesia gas like this.Because the catheter position of bronchial catheter is darker, be easy in during patient transfers wake states to by general anesthesia state because be equipped with conduit and cough reflection stress of etc.ing of choking in trachea, and when carrying out local anaesthesia with bronchial catheter, drop is comparatively large is directly also easy to allow patient choke when instilling inner surface of trachea and coughs.
Summary of the invention
The purpose of this utility model is to solve the problem easily causing malaise symptoms such as coughing of choking when existing double lumen endobronchial tube inserts in patient airway, providing a kind of structure simple, the double lumen endobronchial tube with local anesthesia function compact to design.
This utility model adopts following technical scheme: a kind of double lumen endobronchial tube with local anesthesia function, comprise main endotracheal tube, the outer wall of described main endotracheal tube is provided with bronchial catheter, the lower end of described main endotracheal tube is provided with the first inflatable cuff, the lower end of described bronchial catheter is provided with the second inflatable cuff, the lateral wall of described main endotracheal tube is provided with the first inflating catheter and the first nebulization catheter, the lower end of described first inflating catheter connects the first inflatable cuff, the lateral wall of described bronchial catheter is provided with the second nebulization catheter and the second inflating catheter, the lower end of described second inflating catheter connects the second inflatable cuff, the upper end of described first inflating catheter and the second inflating catheter is respectively arranged with charge valve, the upper end of described first nebulization catheter and the second nebulization catheter is connected with syringe respectively by check valve, described first nebulization catheter end forms the first atomization circle at the lower ending opening place of main endotracheal tube for one week along main endotracheal tube outer wall, described first atomization circle is provided with some apertures, described second nebulization catheter end forms the second atomization circle at bronchial catheter lower ending opening place for one week along bronchial catheter outer wall, described second atomization circle is provided with some apertures.
Further, the diameter of described first nebulization catheter and the second nebulization catheter is 0.5 ~ 1mm.
Further, the caliber diameter 0.8 ~ 1.5mm of described first atomization circle and the second atomization circle.
This utility model structure is simple, compact to design, easy to use, compared with traditional double lumen endobronchial tube, atomization circle is formed respectively at the lower ending opening place of bronchial catheter and main tracheostomy place, on the bronchus that local anaesthetics is sprayed to patient in vaporific in atomization circle and main inner surface of trachea, the effect of local anesthesia can be played, alleviate patient because of tracheal intubation and stimulate the discomfort caused.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: main endotracheal tube 1, bronchial catheter 2, first inflatable cuff 3, second inflatable cuff 4, first atomization circle 5, second is atomized circle 6, first nebulization catheter 7, second nebulization catheter 8, check valve 9, syringe 10, first inflating catheter 11, second inflating catheter 12, charge valve 13.
Detailed description of the invention
