Description

Multifunctional trachea cannula

Technical Field

The invention relates to the technical field of medical ventilation equipment, in particular to a multifunctional trachea cannula.

Background

The artificial airway is a gas channel established by placing a catheter into the trachea through the upper respiratory tract or directly into the trachea. The artificial airway is an effective connection established between the physiological airway and air or other air sources for ensuring the airway to be unobstructed, and provides conditions for effective drainage, obstruction, mechanical ventilation and treatment of pulmonary diseases of the airway. The most common artificial airways are tracheal intubation (oral, nasal) and tracheotomy. Most patients who perform endotracheal intubation and tracheostomy have sputum formation for several reasons: diseases such as pulmonary infection and pulmonary edema due to the disease itself; the cough reflex and the weakening of functions are eliminated due to the self and sedation of the artificial airway, and the accumulation of sputum is increased, because the establishment of the artificial airway loses the cough and expectoration capacity; insertion of an artificial airway into the trachea stimulates the tracheal mucosa resulting in increased secretions.

At present, a sputum suction method during trachea cannula and trachea incision catheterization is usually adopted at certain intervals, sputum accumulates in a certain amount in a trachea, and the sputum suction pipe is inserted into an artificial airway to reach the trachea so as to suck and clean the sputum reaching the trachea and the artificial airway in the lung. The insertion of the sputum suction tube stimulates the patient greatly, and repeated insertion of sputum suction can also cause damage to tracheal mucosa. During sputum aspiration, ventilation of the patient through the artificial airway is affected, sputum aspiration time can only be controlled within 15-20 seconds each time, discomfort and hypoxia of the patient can be caused due to overlong time, and sputum aspiration of the patient with more sputum is carried out for several times, so that time and labor are consumed, and discomfort of the patient is increased. In the process of sucking sputum, the tail end opening of the sputum suction tube is often blocked by sucking soft tissues, not only the inconvenience of sputum suction operation is caused, but also the injured tissue part is easily caused by the excessively strong suction force of the sputum suction tube, so that the artificial airway used at present is really to be improved.
