Description

Tracheal tube with segmented air bag

Technical Field

The utility model belongs to the technical field of medical equipment, and in particular relates to a tracheal cannula with a segmented air bag.

Background Art

Tracheal cannula technology refers to a medical treatment method in which the trachea is cut open at the patient's throat, a metal cannula is inserted at one end, and the airway is connected to the outside to ensure that the airway is unobstructed and facilitate ventilation and oxygen supply. The tracheal cannula is generally used in conjunction with a ventilator. Tracheal cannula is widely used in patients with respiratory obstruction, those whose airway is blocked by lower respiratory tract secretions, patients with respiratory failure, and patients with cardiac or respiratory arrest who need ventilator-assisted ventilation. It is also an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. When performing tracheal cannula surgery, the patient's airway needs to be cut open, the cannula is inserted into the patient's airway, and the pipeline is fixed by means of an airbag, and then the tracheal cannula is connected to the ventilator. Some critically ill patients with weak spontaneous breathing need to keep the tracheal cannula connected to the ventilator for a long time. Fixing the airbag to open the airway can prevent oral saliva from flowing into the airway, prevent bleeding from the incision, and play a role in compression and hemostasis, which plays a certain preventive role in diseases such as lung infection. Leaving the tracheal tube in place for a long time will cause the fixed airbag to compress the tissue in the same part of the airway for a long time, affecting the blood supply to the tissue, causing tissue damage, and even causing tissue necrosis in severe cases.
