Compared with the prior art, the beneficial effect of trachea cannula of this application lies in, is equipped with plastics elastic support body like plastic spring in the intubate for the holistic crushing resistance of trachea cannula and pliability are better than adopting steel wire spring, avoid appearing trachea cannula and roll over flat and block up the trachea and cause the problem of ventilating not smoothly, and it can still keep trachea cannula unblocked under the condition of rolling over, prevents the emergence of medical accident.

[ description of the drawings ]

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

[ detailed description ] embodiments

The present application will be further described with reference to the following drawings and specific embodiments.

Referring to the attached drawing 1, the trachea cannula comprises a cannula body 1 and a gasbag pipeline 2 connected with the cannula body, a sac cavity is arranged in the gasbag pipeline 2, an inflation pipeline 3 communicated with the sac cavity is arranged on the pipe wall on one side of the cannula body 1, a hollow plastic elastic support body 6 extending into the gasbag pipeline is arranged between the inflation pipeline and the pipe wall on the other side in the cannula body 1, an inflation line 4 arranged outside the cannula body 1 is connected to the inflation pipeline 3, and a control device 5 used for controlling the on-off of the inflation line is arranged on the inflation line 4. In this embodiment, the intubation tube body and the plastic elastic support body are made of PVC material, so that the endotracheal intubation has good elasticity and flexibility. Specifically, the plastic elastic support body is made of a spiral material such as a plastic spring, so that the overall pressure resistance and flexibility of the tracheal cannula are better than those of a steel wire spring, and the problem of unsmooth ventilation caused by blockage of the trachea due to collapse of the tracheal cannula is avoided.

Further, the gasbag pipeline 2 is connected through hot melt adhesive with the intubate body 1, and the adhesion is closely knit, avoids body gas leakage, and the pipe diameter of gasbag pipeline 2 is the same with the pipe diameter of intubate body 1, and is whole pleasing to the eye, inserts patient's intraductal more smooth. The air bag pipeline 2 is made of medical silica gel and comprises an inner tube 21 and an air bag 22 arranged on the periphery of the inner tube, and the air bag cavity is formed between the air bag 22 and the inner tube 21. In this embodiment, gasbag 22 is direct through the outer pipe wall blow molding of gasbag pipeline, and integrated into one piece is in gasbag pipeline and cladding in the pipeline outer wall, and preparation simple process, and it does not have the fold for it is more smooth when inserting patient's trachea, avoids trachea cannula's front end to cause the damage to patient's laryngopharynx air flue at the intubate in-process.

The control device 5 comprises an indicating balloon and a control valve arranged in the indicating balloon. In this embodiment, the control valve is the check valve, inserts the assigned position back when trachea cannula, and medical personnel will inflate toward the gasbag and instruction sacculus through the check valve, when not having pressure monitoring equipment, can judge about according to the degree of inflation that instructs the sacculus whether reach the standard. The inflated air bag seals the space between the tracheal cannula and the tracheal wall, so that the auxiliary breathing or the control of breathing are facilitated, and vomit, oral secretion or blood can be prevented from flowing into the trachea.

In order to facilitate the trachea cannula not to damage the organ and tissue of the patient when the trachea cannula is placed and taken, in the embodiment, the end, far away from the inflation pipeline 3, of the air bag pipeline 2 is provided with the olecranon part 23, the pipe wall of the olecranon part 23 is provided with the Murphy's eye 24, and the trachea is easily prevented from being damaged by the trachea body through a narrow human body cavity.

In addition, the trachea cannula is also provided with a trachea cannula joint 11, and the trachea cannula joint 11 can be connected with a breathing machine or an anaesthesia machine to supply oxygen or administer medicine for a patient.

In summary, the tracheal cannula of the present application has the following advantages:

1. be equipped with plastics elastic support body like plastic spring in the intubate for the holistic crushing resistance of trachea cannula and pliability are better than adopting steel wire spring, avoid appearing the trachea cannula and roll over flat and block up the trachea and cause the problem of not smooth of ventilating, and it can still keep trachea cannula unblocked under the circumstances of folding, prevents the emergence of medical accident.
