The trachea cannula technology is widely applied to various emergency sites in emergency departments, various ICUs, anesthesia departments, various wards and outside hospitals. The technology can provide optimal conditions for ventilation, oxygen supply, respiratory tract suction and the like.

Trachea cannula generally includes the intubate body and sets up the gasbag on the intubate body, and the gasbag is aerifyd the back and is fixed on patient's trachea, avoids intubate body not hard up. In practice, the body of the cannula will typically reach the trachea near the bronchi. After the operation is completed, the medical personnel will generally release a portion of the gas within the bladder in order to reduce the pulmonary pressure and discomfort to the patient. However, this results in a reduction in the stability of the fixation of the endotracheal tube. When the emotion of a patient is excited or the action amplitude of the patient is large, the tracheal intubation can move up and down in the trachea, and the air bag can move along with the tracheal intubation in the up-and-down movement process. If the trachea cannula moves downwards into one of the trachea, when the air bag blocks the mouth of the bronchus, only one lung lobe on one side works, and the lung lobe on the other side is extruded, so that blood supply of a patient is influenced, and great discomfort is brought to the patient.

For the above situation, it is now common practice to pull out the endotracheal tube and then reinsert it after the patient is calm. Reinsertion of the endotracheal tube still causes discomfort to the patient and does not completely solve the above problems. Therefore, it is desirable to provide an endotracheal intubation structure that effectively solves the above problems.

Detailed Description

As shown in fig. 1 and 2, the present invention discloses an endotracheal intubation structure, which includes an intubation body 10, wherein a first airway 11 and a second airway 12 isolated from each other are formed in the intubation body 10, and the first airway 11 penetrates the intubation body 10 in the length direction of the intubation body 10. An annular air bag 20 is arranged outside the cannula body 10, a buffer strip 30 is formed between the air bag 20 and the cannula body 10, the second air passage 12 is communicated with the second air passage 12 through the buffer strip 30, and the air bag 20 is isolated from the first air passage 11.

The utility model discloses set up gasbag 20 into cyclic annular to set up the buffering area 30 between gasbag 20 and intubate body 10. When the intubation tube body 10 moves, the buffering belt 30 is firstly driven to shift, only when the intubation tube body 10 moves for a larger distance, the airbag 20 is driven to move together, and the moving distance of the airbag 20 is far smaller than that of the endotracheal intubation. Therefore, when the patient is excited or moves greatly, the caused trachea may not move the air bag 20 or only can move the air bag 20 for a small distance, thereby effectively avoiding the occurrence of the phenomenon that the air bag 20 blocks the bronchus and effectively avoiding the discomfort brought to the patient.

With continued reference to fig. 2, in the present embodiment, the cushion belt 30 includes two cushion sheets 31, a channel 32 is formed between the two cushion sheets 31, and one end of the channel 32 is communicated with the second air passage 12, and the other end is communicated with the air bag 20. In one embodiment, the cushion sheet 31 is made of a flexible material, so that the flexible material itself can generate a certain cushion distance, thereby reducing the moving distance of the airbag 20. In another embodiment, as shown in fig. 3, the cushion 31 is configured to be wavy, and when the endotracheal tube moves, the cushion 31 is moved with the cushion, and the balloon 20 is moved after the wavy shape of the cushion 31 is expanded as much as possible, thereby further reducing the moving distance of the balloon 20.

The endotracheal tube is generally connected to a ventilator when in use, so one end of the tube body 10 is a ventilator port 13, and the other end is a ventilation opening 14. The second airway 12 is disposed within the cannula body 10 between the ventilator interface 13 and the balloon 20.
