Description

Scratch-resistant double-cavity tracheal catheter with easily-positioned air bag

Technical Field

The utility model relates to a tracheal catheter, especially an easy location gasbag prevents scraping brokenly type two-chamber tracheal catheter belongs to two-chamber tracheal catheter's technical field.

Background

The lung isolation technology is an important and indispensable component for ensuring the safety of a patient and the smooth operation during the chest surgery anesthesia, wherein the double-cavity tracheal catheter is the most main and ideal instrument for the lung isolation operation, single-side lung ventilation or double-side lung ventilation can be carried out through the double-cavity tracheal catheter, so that secretion and blood of an affected lung cannot flow into a healthy side bronchus, and the leakage test and lung refolding of the affected lung can be carried out without the need of putting the double-cavity tracheal catheter into an air passage before closing the chest after the operation.

Although the existing double-cavity tracheal catheter can ventilate the left lung and the right lung respectively, the key to the success of the existing double-cavity tracheal catheter is to accurately position the left lung and the right lung: when the double-cavity tracheal catheter enters too deeply, the ventilation opening of the main ventilation tube is completely or partially embedded into the healthy side main ventilation tube, so that the collapse of the lung at the affected side is bad, the operation is affected, meanwhile, the tip tube wall of the branch ventilation tube or the cuff of the branch ventilation tube can block the opening of the lung lobes at the healthy side, so that part of the lung lobes are not ventilated, hypoxemia is caused, and when the double-cavity tracheal catheter enters too shallowly, the isolation of the double lungs is failed.

Therefore, how to quickly and accurately position the dual lumen tube has been a difficult problem! Especially right side two-chamber endotracheal tube, because the terminal cuff middle part of ordinary right side two-chamber endotracheal tube is equipped with the side hole to the upper right lung lobe opening ventilation, it is often difficult with the upper right lung lobe opening counterpoint in the use, and the two-chamber endotracheal tube that the intraoperative two-chamber endotracheal tube has the slight forward movement or retreat of the two-chamber endotracheal tube that tractive or position slightly change etc. cause can lead to the upper right lung lobe opening by cuff or the pipe wall of two-chamber endotracheal tube block up, cause hypoxemia, often need repeatedly to adjust in the art, both influenced the operation process, can cause the damage to the air flue.

Because the diameter ratio of the double-cavity tracheal catheter is larger than that of the general tracheal catheter, the curvature is special, and the side hole design of the right double-cavity tracheal catheter and the design that the main sleeve sac body is longer (about 50 mm), the distance from the upper edge of the main sleeve sac to the main pipe interface of the main tracheal catheter is longer (about 130 mm), and the distance is just close to the distance between the incisors and the glottis (130 mm-150 mm), therefore, when the double-cavity tracheal catheter is inserted into the glottis, particularly when a difficult airway is encountered, repeated attempts are often needed, the situation that the main sleeve sac of the double-cavity tracheal catheter is hung by the teeth of a patient easily occurs in the process that the double-cavity tracheal catheter goes back and forth from the oral cavity, and the double-cavity tracheal catheter is. In addition, due to the particularity of the posture of the thoracic surgery, once the cuff rupture is found after the start of the surgery, it is very difficult to replace the catheter, which causes great troubles to the surgery. Moreover, double lumen endotracheal tubes are expensive and replacing a new tube increases the medical cost of the patient.
