Description

A new visual tracheal tube with subglottic double suction

technical field

The invention relates to a medical catheter, in particular to a tracheal catheter.

Background technique

The ventilator has become a commonly used life support device in the critically ill unit, and mechanically ventilated patients need to use a tracheal tube to establish an artificial airway. The tracheal tube not only has the common inherent disadvantage of destroying the respiratory defense barrier, but more importantly, damages the epiglottis and glottis. Physiological defense function, leading to a significant increase in the chance of aspiration of oropharyngeal secretions and gastric contents into the airway. Studies at home and abroad have confirmed that transient air sac pressure reduction and body position changes will cause the retentate on the air sac to enter the lower respiratory tract through the gap between the inner wall of the trachea and the catheter, which is one of the important pathogenesis of VAP. Although the endotracheal tube with subglottic suction has been used clinically, it is still impossible to completely remove the retention in the fold between the air bag and the endotracheal tube and at the lowest point of the air bag, due to the mechanical compression and stimulation of the endotracheal tube on the oropharynx and glottis , falling back of the tongue, etc., the airway cavity above the airbag is often in a negative pressure state when removing the retentate on the airbag. In the process of suction, it is easy to damage the airway wall mucosa, resulting in bleeding, erosion, and even ulceration. In addition, due to the inherent shortcomings of the shape of the endotracheal tube used in clinical practice, the fixed radian tends to cause the lower end of the endotracheal tube to always be close to the front wall of the trachea, mechanical friction caused by various reasons (such as body position changes) When the endotracheal tube is used, it can damage the mucosa of the tracheal wall and cause local mucosal ulceration. At present, it is impossible to avoid this problem by adjusting the position of the tip of the endotracheal tube clinically.
