The clinical operation of the tracheal intubation is shown in fig. 1, an anesthesiologist stands at the head side of a patient, the left hand takes the laryngoscope 100 to enter the oral cavity of the patient, gently lifts the tongue and the epiglottis of the patient forwards and upwards to expose the glottis 300 (namely, the tracheal opening), the right hand takes the tracheal catheter 200 to be placed into the oral cavity, the tracheal catheter is placed into the trachea of the patient to a proper depth through the glottis (namely, the tracheal opening), then the laryngoscope is taken out, a proper amount of air is injected into the inflation port of the balloon by the injector to fill the balloon so as to seal the trachea of the patient, the tracheal catheter is fixed in the trachea to prevent and treat the escape, and finally, a breathing machine or an.

In the operating room, most patients to be treated by surgery are also intubated with a trachea after general anesthesia to maintain the patient's oxygen needs during surgery. Generally, patients are under general anesthesia before tracheal intubation, namely intravenous injection of analgesics, sedatives and muscle relaxants is performed, spontaneous respiration and laryngopharynx reflex of the patients are eliminated, and choking or spasm of the throat and the airway of the patients caused by stimulation of the tracheal catheter is avoided. However, sometimes the patient still may have throat reflex and cough when inserting the tracheal catheter under general anesthesia, for example, when rescuing the patient, the patient may not have time to wait for the sufficient effect of the anesthetic, and the possibility of choking cough of the patient is very high when the anesthetic intubates the trachea of the patient needing to be rescued.

When the tracheal catheter is placed in the throat and trachea of a patient, if the patient is choked and severely breathes, the throat or trachea of the patient is extremely easy to spray respiratory secretion, aerosol and blood in the respiratory tract to pollute the face, head, hand or chest clothes of a intubator. At present, no tracheal catheter or device capable of preventing the tracheal intubation doctor from being polluted by the respiratory secretion choked and coughed by the patient exists clinically, and the problem needs to be solved urgently.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, an object of the present invention is to provide a tracheal catheter set capable of preventing respiratory tract secretion from polluting doctors, and to solve the technical problem that the respiratory tract secretion easily pollutes doctors in the existing tracheal intubation process.

The utility model adopts the following technical scheme:

the tracheal catheter set capable of preventing respiratory secretions of a patient from polluting doctors comprises a concave cover, a main pipe is led out from the inner top of the concave cover, and an air hole is formed in one end, facing the concave cover, of the main pipe.

Furthermore, the edge position part of the concave cover extends outwards to form a duck tongue wing.

Furthermore, the air holes are round air holes or strip-shaped air holes and are arranged on the outer wall of the main pipe.
