Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a trachea cannula.

Background

The trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction. Generally, a large amount of saliva, phlegm and other secretion are generated due to natural reaction of the oral cavity to inserted foreign matters, various liquids are mixed together to form accumulated phlegm, and the secretion is easy to adhere to the tracheal cannula, so that discomfort on the sense of a patient is caused, the ventilation effect of the tracheal cannula is influenced, a space for permanent planting and growth of germs is provided, and infection is easy to cause. Therefore, sputum on the tracheal cannula needs to be sucked regularly during the nursing process of the tracheal cannula, but some of the secretions are viscous, so that the sputum is difficult to be sucked completely, and serious diseases such as pneumonia and the like are easily caused if the sputum flows to the lung carelessly. Because trachea cannula stretches into patient's respiratory track, medical personnel can't learn the condition in the respiratory track, can't judge whether have sputum to block up the intubate, and when driving thick sputum in the intubate sometimes, need extract the clearance with the intubate, intubate again, and repeated many times intubate not only increases medical personnel's working strength, still increases patient's misery simultaneously.
