Description

Wall-attached bronchial occluder of combined tracheal catheter
Technical Field
The invention belongs to the technical field of design of medical mechanical equipment, and particularly relates to a tube wall attached type bronchus stopper combined with a tracheal catheter.
Background
When a patient in a thoracic operation is ventilated in one lung, the plugging device is a common medical instrument for closing one side of the lung to ventilate. At present, the bronchial occluder is often combined with a single-cavity tracheal catheter in clinic. The bronchus occluder comprises an inflatable structure, a sleeve and an air bag, and in practical operation, the bronchus occluder is inserted into a ventilation tube cavity of a tracheal catheter for use, then the air bag of the bronchus occluder is inserted into a bronchus at a target side under the guidance of a fiberbronchoscope, and the air bag is inflated, so that the air bag of the bronchus occluder occludes the bronchus at the target side, and after a lung at the target side is collapsed, the bronchus occluder is beneficial to expanding the operation visual field, so that a surgeon can observe a diseased organ more clearly, and operation is facilitated. However, for infants or infants, the inner diameter of the ventilation lumen of the tracheal catheter is small, which is not enough for placing a bronchial stopper in the tracheal catheter and is not beneficial to special operations such as sputum suction. The external bronchus stopper of the tracheal catheter can become an effective choice at this time.
However, there are still many problems with the external bronchus stopper, for example, the conventional bronchus stopper placed outside the trachea needs to be fixed by an adhesive tape, and there are many inconveniences when the position of the stopper needs to be temporarily replaced or adjusted. If the external bronchus stopper fixed by the adhesive tape is not firmly fixed, the external bronchus stopper is easy to displace, and particularly, the external bronchus stopper which is not firmly fixed is easy to displace in the process of placing the surgical body position. Therefore, the change of a series of respiratory parameters such as ventilation change, airway pressure increase, end-expiratory carbon dioxide increase and the like of the infant is caused, the blood oxygen saturation is instantly reduced, the life of the infant is endangered by serious patients, and unnecessary risk factors are brought to the infant.
In some related arts, based on the foregoing problems, there is a method of disposing the related bronchial stopper outside the endotracheal tube so as to no longer occupy the inner space of the ventilation lumen, but there is a risk of injury to the trachea of the patient in the manner of disposing the related bronchial stopper outside the endotracheal tube, and there are many disadvantages in terms of positioning of the bronchial stopper.
