Trachea catheter

Abstract

The invention discloses a trachea catheter. The trachea catheter comprises a catheter body, a first gasbag and a second gasbag. An encapsulating structure which is used for sealing an opening is arranged at the opening of the front end of the catheter body, the first gasbag is arranged at the outer wall of the catheter body and is communicated with a first inflating pipe, the second gasbag is arranged at the outer wall of the catheter body and is communicated with a second inflating pipe, and the second gasbag is located at the rear side of the first gasbag. The catheter body is provided with a vent hole, and the vent hole is located between the first gasbag and the second gasbag. In the trachea catheter, by arranging the first gasbag and the second gasbag on the catheter body, and forming the vent hole in the catheter body between the first gasbag and the second gasbag, one-lung ventilation and dual-lung ventilation can be conveniently achieved, and the trachea catheter can be switched between the one-lung ventilation and dual-lung ventilation. The trachea catheter is simple in operation, the frequency of inserting and extracting the trachea catheter is reduced, and the harm to patients is reduced as much as possible.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a trachea catheter. Background technique [0002] When a patient's left or right lung is diseased, it is necessary to isolate the left and right lungs so that the left and right lungs can be ventilated separately to prevent the affected lung from infecting the healthy lung. During the treatment, both lungs need to be ventilated simultaneously or only one lung should be ventilated. For these purposes, an endotracheal tube is required. [0003] There are three types of common endotracheal tubes. The first type is a single-lumen endotracheal tube, which has a balloon on it. The single-lumen endotracheal tube is inserted into the main bronchi of one lung, and the air outlet of the single-lumen endotracheal tube is inserted into the single-lumen endotracheal tube. In the main bronchus of the lateral lung, the balloon is inflated, and the balloon blocks the main bronchus of one lung,...

[0003] There are three types of common endotracheal tubes. The first type is a single-lumen endotracheal tube, which has a balloon on it. The single-lumen endotracheal tube is inserted into the main bronchi of one lung, and the air outlet of the single-lumen endotracheal tube is inserted into the single-lumen endotracheal tube. In the main bronchus of the lateral lung, the balloon is inflated, and the balloon blocks the main bronchus of one lung, which isolates the two lungs and can ventilate one lung with a single-lumen endotracheal tube, but needs to switch to a double When the lung is ventilated, the patient needs to be intubated again, which is cumbersome to operate and makes the patient very painful, and cross-infection is prone to occur during the insertion and extraction process

The second type is a double-lumen endotracheal tube. The double-lumen endotracheal tube has two lumens, corresponding to the left lung and the right lung respectively. There is also an air bag on the double-lumen endotracheal tube. When the air bag is inflated, the left lung can be isolated from the right lung. Open, but the double-lumen trachea has the following disadvantages: the outer diameter of the catheter is relatively thick, which is easy to damage the respiratory tract during tracheal intubation, and is not suitable for patients with thinner trachea; the inner diameter of the single side of the double-lumen tube is small, which is not conducive to ventilation prone to airway hypertension

The third type is a single-lumen endotracheal tube combined with a bronchial occluder. During operation, the bronchial occluder is inserted into the main bronchus of one lung, and the air bag on the bronchial occluder is inflated to achieve isolation of both lungs, but the bronchi The inner diameter of the catheter of the occluder is small, and it is difficult to install a suction tube in the catheter of the bronchial occluder to suck out the secretions of the lungs
