According to the above tracheal intubation tube, the balloon tube is connected to the intubation tube body by hot melt adhesive, and the diameter of the tube is the same as that of the intubation tube body.

According to the above-mentioned tracheal intubation tube, the balloon tube is provided with a balloon that is integrally formed in the tube and covers the outer wall of the tube.

As described above for the tracheal intubation tube, the end of the balloon tube away from the inflation tube is provided with an olecranon.

As for the above-mentioned tracheal intubation tube, the tube wall of the olecranon part is provided with a Murphy hole.

Compared with the prior art, the beneficial effect of the tracheal intubation of the present application is that the intubation tube is provided with a plastic elastic support such as a plastic spring, so that the overall compression resistance and flexibility of the tracheal intubation are better than that of a steel wire spring, avoiding When the tracheal intubation is collapsed and the trachea is blocked to cause poor ventilation, it can still keep the tracheal intubation unimpeded under the discounted situation, so as to prevent medical accidents.

【Description of drawings】

Fig. 1 is a schematic structural view of the endotracheal tube of the present application.

【Detailed ways】

The present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to accompanying drawing 1, a kind of endotracheal intubation, comprises intubation body 1 and the balloon tube 2 that is connected with intubation body, and described balloon tube 2 is provided with cavity, and the tube wall of one side of described intubation body 1 An inflation conduit 3 communicating with the cavity is provided, and a hollow plastic elastic support body 6 extending into the conduit of the airbag is provided in the cannula body 1 between the inflation conduit and the other side wall, so that The inflation pipeline 3 is connected with an inflation line 4 arranged outside the cannula body 1, and the inflation line 4 is provided with a control device 5 for controlling the on-off of the inflation line. In this embodiment, the intubation tube body and the plastic elastic support body are made of PVC material, so that the endotracheal intubation tube has good elasticity and flexibility. Specifically, the plastic elastic support body is made of a helical material such as a plastic spring, so that the overall compression resistance and flexibility of the tracheal intubation are better than those of steel wire springs, and avoid the collapse of the tracheal intubation and blockage of the trachea resulting in poor ventilation The problem.

Further, the balloon tube 2 and the cannula body 1 are connected by hot-melt adhesive, and the bonding is dense to avoid air leakage from the tube body, and the diameter of the balloon tube 2 is the same as that of the cannula body 1, which is overall beautiful and easy to insert into the patient. The trachea is relatively smooth. The air bag pipeline 2 is made of medical silica gel, and includes an inner tube 21 and an air bag 22 arranged on the outer periphery of the inner tube, and the air bag cavity is arranged between the air bag 22 and the inner tube 21 . In this embodiment, the airbag 22 is directly blow-molded by the outer tube wall of the airbag duct, integrally formed on the airbag duct and coated on the outer wall of the duct. To prevent the front end of the endotracheal tube from causing damage to the patient's throat airway during intubation.

The control device 5 includes an indicating balloon and a control valve arranged in the indicating balloon. In this embodiment, the control valve is a one-way valve. When the tracheal intubation is inserted to the designated position, the medical staff will inflate the airbag and the indicator balloon through the one-way valve. When there is no pressure monitoring equipment, according to the inflation of the indicator balloon The degree can roughly determine whether the expansion degree of the airbag has reached the standard. The inflated air bag seals the space between the endotracheal tube and the tracheal wall, which facilitates breathing assistance or control, and also prevents vomit, oral secretions, or blood from flowing into the trachea.

In order to facilitate endotracheal intubation without damaging the patient's organs and tissues when the tube is placed and taken out, in this embodiment, the end of the balloon tube 2 far away from the inflation tube 3 is provided with an olecranon part 23, and the tube wall of the olecranon part 23 is provided with ink. The phenotype hole 24 is easy to pass through the narrow human cavity, and avoids the damage of the trachea by the tube body.

In addition, the tracheal intubation tube is also provided with a tracheal intubation joint 11, which can be connected with a ventilator or anesthesia machine to supply oxygen or medicine for the patient.

In summary, the advantages of the tracheal intubation of the present application are as follows:

1. The intubation tube is equipped with a plastic elastic support such as a plastic spring, which makes the overall pressure resistance and flexibility of the tracheal intubation better than that of a steel wire spring, and avoids the problem of poor ventilation caused by the collapse of the tracheal intubation and blockage of the trachea. It can still keep the tracheal intubation unblocked under the condition of discount, and prevent the occurrence of medical accidents.

2. The airbag is blow-molded directly through the outer tube wall of the airbag pipeline, and is integrally formed on the airbag pipeline. The manufacturing process is simple, and it has no folds, which makes it smoother when inserted into the patient's trachea, and avoids the front end of the tracheal intubation. Injury to the patient's throat airway during intubation.

3. The air bag tube is connected to the main body of the endotracheal tube by hot-melt adhesive connection, and the segmental connection is adopted, and the air bag tube is formed separately. Compared with the previous whole endotracheal tube, the production of the tube body is greatly reduced cost.

The above descriptions are only preferred embodiments of the present application, and are not intended to limit the implementation scope of the present application. Others whose principles and basic structures are the same or similar to the present application are within the protection scope of the present application.
