Double-cavity tracheal catheter with air bags capable of being adjusted to be at multiple angles

Abstract

The invention discloses a double-cavity tracheal catheter with air bags capable of being adjusted to be at multiple angles. The double-cavity tracheal catheter with the air bags capable of being adjusted to be at the multiple angles comprises a main pipe, an adjusting mechanism, a left branch pipe, a first air delivery pipe, a second air delivery pipe and a right branch pipe; one end of the main pipe is connected with the adjusting mechanism, and both the left branch pipe and the right branch pipe are connected with the adjusting mechanism; the main pipe communicates with an inner cavity of the adjusting mechanism, the left branch pipe communicates with the inner cavity of the adjusting mechanism, and the right branch pipe communicates with the inner cavity of the adjusting mechanism; in afree state, the left branch pipe and the right branch pipe are splayed, and the adjusting mechanism is used for adjusting a splayed degree of the left branch pipe and the right branch pipe; the leftbranch pipe is sleeved with a first air bag, and one end of the first air delivery pipe is connected with the first air bag, and communicates with the first air bag; and the right branch pipe is sleeved with a second air bag, and one end of the second air delivery pipe is connected with the second air bag, and communicates with the second air bag. According to the double-cavity tracheal catheter with the air bags capable of being adjusted to be at the multiple angles, an orificium fistula in a bronchial bifurcation formed by the right bronchus and the left bronchus can be effectively sealed conveniently according to the requirements, so that the risks of severe pneumonia and asphyxia in a perioperative period are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-lumen endotracheal tube capable of adjusting air bags at multiple angles. Background technique [0002] At present, the incidence of esophageal malignant tumors is high, and patients are generally elderly, with poor physiological functions, and often accompanied by tracheoesophageal fistula. There are symptoms of choking on drinking water and long-term chronic pneumonia, both of which are caused by water or food in the esophagus entering the trachea through the fistula. If such patients need painless gastrointestinal endoscopy or surgical treatment, general anesthesia and tracheal intubation are required to ensure the basic ventilation and airway safety of the patients. At the same time, because the position of tracheoesophageal fistula is variable and the size of the fistula is different, it brings a great test to the treatment. Moreover, when the fistula is l...
