Abstract

The invention discloses a lung isolation catheter which comprises a main tracheal catheter, a bronchial catheter, a first opening and second openings, wherein a first air sac is arranged on the outer wall of the main tracheal catheter and connected with a first inflation valve; the bronchial catheter is connected with the lower end of the main tracheal catheter; a second air sac is arranged on the outer wall of the bronchial catheter and connected with a second inflation valve; a sealing member is arranged inside the bronchial catheter and connected to a third inflation valve through a ventilation pressure control device; the first opening is formed in the tail end of the bronchial catheter; the second openings are formed in the wall at the lower end part of the main tracheal catheter and positioned below the first air sac; and at least two second openings are distributed along the peripheral surface of the main tracheal catheter. The lung isolation catheter disclosed by the invention has more excellent ventilation function than that of the currently applied double-lumen tracheal catheter, is operated more safely, conveniently and efficiently and the risk of the existing double-lumen endotracheal intubation can be reduced.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a lung isolation catheter. Background technique [0002] Tracheal intubation is a commonly used medical consumable in the anesthesia department, especially in thoracic surgery. During the operation, when one-lung ventilation is required, a double-lumen tracheal intubation is required. The purpose is to block the lung ventilation at the surgical site, collapse the lung, expand the surgical field, and facilitate surgical operations. The function of the balloon can be independently ventilated to meet the oxygenation needs of surgical patients. However, in the process of use, we found that due to the different functions of each channel of the double-lumen tube, the diameter of the tracheal intubation tube is larger, and the glottis is usually smaller, and some patients even have unilateral vocal cord paralysis and cannot open it. , Therefore, it is easier to damage the vocal cords during intu...
