Description
Technical Field
The embodiment of the utility model provides a relate to the air flue and trade pipe technical field, concretely relates to visual air flue trades pipe device.
Background
In clinical work, when a patient needs mechanical ventilation, the tracheal intubation bi-pulmonary ventilation is adopted in clinical practice. Or performing unilateral lung blocking and single lung ventilation during thoracic surgery. Endotracheal tubes have been an important airway tool widely used for assisted ventilation of patients, which allows for rapid and efficient establishment of artificial airways. However, due to the complexity of human anatomy and the difference of tolerance of airway mucosa, airway mucosa injury, difficult intubation and displacement of the tube body of the endotracheal tube often result in poor ventilation and even the tube falls out of the trachea, which finally results in ventilation failure and even causes serious complications such as asphyxia. In addition, the traditional trachea cannula, the double-cavity trachea cannula and the bronchus stopper can not carry out visual management on the airway of a patient in the ventilation process, if the depth or the position of the tracheal catheter needs to be adjusted in clinical work, the depth or the position of the tracheal catheter is often invisible to naked eyes, so the adjustment process of the tracheal catheter in the trachea belongs to blind detection operation, the injury to the airway and accessory structures of the airway, such as a glottis, a cricoarytenoid and the like, even irreversible physiological structure damage is caused, time is wasted, the hypoxia time of the patient is prolonged, and even the rescue time of the patient is delayed. The main reasons are as follows:
firstly, the trachea intubation technology is used as an important ventilation method used in the general anesthesia operation or cardiopulmonary resuscitation and the rescue process of critically ill patients accompanied with respiratory dysfunction, and the key problems in the current clinical work are how to improve the success rate of intubation of the trachea and difficult airways under the oral direct vision, shorten the intubation time and reduce the damage to the airways in the routine clinical trachea intubation process. In clinic, if a patient with a difficult airway needs to replace a tracheal catheter, or a patient in the thoracic department needs to replace a double-lumen tracheal catheter with a single-lumen tracheal catheter, a tube exchanger is often used as a guiding tool, namely, a thin tube exchanger is firstly inserted into the tracheal catheter inserted into the airway, then the inserted tracheal catheter is pulled out to the outside along the tube exchanger, after the inserted tracheal catheter is pulled out to the outside and is separated from the tube exchanger, a new tracheal catheter is sleeved into the tube exchanger, the catheter is placed into the airway along the path of the tube exchanger, and finally a tracheal cannula is placed under the guidance of the tube exchanger, so that the purpose of guiding the tracheal catheter or tube replacement is achieved. The traditional tube exchanger is a bendable and scale-free plastic solid guide core and is mainly used for guiding a tracheal catheter to be placed into a trachea, but after the traditional tube exchanger is placed, an operator cannot visually see the placing process of the tube exchanger, so that whether the placing depth of the tube exchanger is positioned in the trachea or not cannot be accurately judged, whether the front end of the tube exchanger punctures the trachea wall or not cannot be judged when the tube exchanger is placed, and the failure of placing the tracheal catheter due to the fact that the tube exchanger does not break off the gas channel in the process of replacing the tracheal catheter by using the tube exchanger cannot be ensured.
Secondly, the double-cavity tracheal catheter is used as an important tool for assisting mechanical ventilation in the operation of a patient in the department of thoracic diseases, and the double-cavity tracheal catheter is arranged in the operation and can separate the sick side lung and the healthy side lung of the patient in an isolating way so as to prevent the secretion and pathogenic bacteria of the sick side lung from spreading to the healthy side lung to cause acute respiratory obstruction or the risk of infection of the healthy side lung. The double-cavity tracheal catheter can realize independent or synchronous ventilation of the single lung of a chest cavity lung operation or a critical patient, ventilation of the healthy side lung and the single lung of an intraoperative healthy side lung and ventilation of an affected side lung pause, so as to meet the requirements of intraoperative operations. After the operation, the two lungs are ventilated to avoid atelectasis and lung collapse after the operation. The operation of clinical double-cavity tracheal catheter implantation is complex, a large amount of clinical treatment is needed, and the standard ventilation method for effectively establishing pulmonary isolation ventilation and single-lung ventilation in clinical work is provided at present. However, in clinical practice, the main tube of the conventional double-lumen endotracheal tube has a large cross-sectional area, and no visible probe is provided, so that the damage of the blind intubation process of the conventional double-lumen endotracheal tube is large, which may cause damage to the physiological anatomical structure of the glottis, scratch or even tear of the tracheal wall, and serious adverse clinical events. In addition, the double-lumen tracheal catheter has the external force oppression on the trachea in clinical work due to the thick outer diameter, so the tracheal external force oppressive injury of a patient is easily caused in the maintaining process and the tube drawing process after the double-lumen tracheal catheter is placed.
Namely, the problems of airway damage and inaccurate positioning of the traditional trachea cannula, the double-cavity bronchial cannula and the like in the prior art under the condition of non-visual operation.
