Trachea cannula

Abstract

A trachea cannula comprises a main trachea, a trachea connector installed at the top end of the main trachea, an air bag installed at the bottom of the main trachea, an inflation pipe connected with the air bag, and an inflation valve installed at the top end of the inflation pipe. A left bag upper suction tube and a right bag upper suction tube are arranged on the two sides of the main trachea. Two groups of side openings on the left side and the right side are formed in the position, 5-10 mm above the air bag, of the main trachea. Each group of side openings includes 2-4 side openings. The lower port of the left bag upper suction tube and the lower port of the right bag upper suction tube correspond to two groups of side openings, wherein one group of side openings are air inlets, and the other group of side openings are fluid exhaust openings. Sputum, extravasated blood and other secreta generated by a respiratory tract of a patient can be sucked out, the pressure in the respiratorytract is balanced, the symptoms of respiratory distress, oxygen saturation rapid drop and the like are avoided, and the critical illness risk of the patient is reduced.

Description

technical field [0001] The present invention relates to a medical device, in particular to a tracheal intubation tube. Background technique [0002] Endotracheal intubation is an important medical device in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. Endotracheal intubation can provide sufficient oxygen for patients and keep the airway open at any time. The most effective and quickest way to establish an artificial airway. During the process of tracheal intubation, the laryngeal tube will produce secretions such as sputum and congestion. The existing tracheal intubation cannot remove the secretions produced in the laryngeal tube in time. Or when the flow out of the incision opening, it will cause the pressure in the patient's airway to increase, and symptoms such as respiratory distress and a rapid drop in oxygen saturation will occur, and the risk of the patient's critical illness is high.
