In order to achieve the above purpose, the utility model adopts the following technical scheme: a Y-shaped tracheal catheter with a one-way valve comprises a tracheal catheter, wherein the tracheal catheter comprises a tracheal tube, the front end of the tracheal tube is provided with a cuff, the rear end of the tracheal tube is connected with a catheter joint, an inflation connecting tube is connected to the outer side of one end of the tracheal tube close to the catheter joint and communicated with the cuff, and the tail end of the inflation connecting tube is connected with an indication balloon; the side pipe is communicated with the other side of the air guide pipe with the position different from that of the inflating connecting pipe, the inner diameter of the side pipe is the same as that of the air guide pipe, an acute angle is formed between the side pipe and the air guide pipe, a one-way valve is arranged in the side pipe, a spiral is arranged at the opening of the end part of the side pipe and is provided with a spiral cover, the narrow end of the one-way valve faces inwards, and the wide end of the one-way valve faces the spiral cover.
The utility model discloses following beneficial effect has: when the device is used, the suction in the airway or the bronchofiberscope examination can be carried out under the condition of not interrupting the mechanical ventilation in the operation, the device is particularly beneficial to a part of patients needing to be treated under the bronchofiberscope for a long time, and the oxygen deficiency in the operation and the interruption of the operation process are not needed to be concerned, so that the life safety of the patients are ensured, and the operation is smoothly carried out. The device designs endotracheal tube and side pipe into the Y type for mechanical ventilation and suction, fiberoptic bronchoscopy treatment no longer share an entry like traditional method, the device has two entries, mutual noninterference between them, the important thing is that the device has installed the one-way flap on the inner wall of side pipe, the one-way flap can avoid the interior gaseous leakage of lung to lead to the patient oxygen deficiency during operation, so the device has very positive practical application and spreading value.
