Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to many gasbags two-chamber endotracheal tube.
Background
The single lung ventilation is very important for thoracotomy or thoracoscopic surgery assisted by a television, because the single lung ventilation makes the operation side lung collapse so as to be convenient for exposing the operation field, and the two side lungs are isolated, thereby avoiding the operation side lung secretion or blood from polluting the healthy side lung. Double-lumen tubes (DLTs) are mainly used for unilung ventilation.
When the catheter is inserted into the glottis, particularly when a difficult airway is encountered, repeated intubation is often needed, the situation that the main tracheal cuff of the catheter is easily torn by the teeth of a patient occurs in the process that the catheter goes in and out from the oral cavity, and the catheter is directly scrapped. 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. Furthermore, the double lumen bronchial tubes are expensive and replacing a new tube increases the medical costs for the patient.
